STUDIES IN AUSTRALIAN THYSANURA

NO. 4 MACHILIDE (BRISTLE-TAILS)

BY H. WOMERSLEY

Summary

The Machilidae or Bristle-tails, together with the Lepismatidae or Silverfish, form the ectotrophic

division of the old order Thysanura. Apart from several primitive characters, however, they have

very little in common with the entotrophic division which includes the families Campodeidae,

Japygidae and Projapygidae. The present tendency of taxonomists is to regard them as two distinct

orders, the Ectotrophi ( Thysanura. str.) and the Entotrophi (Diplura).

STUDIES IN AUSTRALIAN THYSANURA

No. 4. MACHILIDAE (BRISTLE-TAILS)

By H. Womers ey, F.R.E.S., A.L.S.

{Read 11 November 1937]

The Maclulidae or Bristle-tails, together with the Lepismatidae or Silverfish,

form the ectotrophic division of the old order Thysanura. Apart from several

primitive characters, however, they have very little in common with the ento-

trophic division which includes the families Campodeidae, Japygidae and Pro-

japygidae, The present tendency of taxonomists is to regard them as two distinct

orders, the Ectotrophi (Thysanura s. str.) and the Entotrophi (Diplura).

The two families of the Ectotrophi may be separated as follows :—

Compound eyes large; ocelli present. Abdominal segments I-VII usually with

one or two pairs of exsertile vesicles. Stylets present on sternites IJ-IX and

usually on some of the thoracic coxae. Thorax generally well arched and not

flattened. Body always scaled. Machilidae

Compound eyes small or absent. Abdomen usually with some stylets and

exsertile vesicles. Thoracic coxal stylets absent. Body much flattened and fish-

shaped, or elongate and parallel-sided. Body scaled or not. Lepismatidae

Bristle-tails or rock-jumpers are rare in Australia, but in many parts of the

world they are to be found in large numbers. Such is the case along the coasts

of Europe, where they frequent the sandstone cliffs. In other parts they can be

found on and under stones on hilly woodsides, as on the lower slopes of Table

Mountain, South Africa. Little is known of their food, but it apparently consists

of minute algae growing upon the rocks where they are found.

These insects are moderately large, measuring up to three-fourths of an inch

in body length, fish-shaped and of a brownish colour which often shows remark-

able reflections as the light falls upon the scaling. They are furnished with two

long filamentous antennae composed of from 30 to 40 segments, each of which

may be subdivided into 10 to 14 small parts. Compound cyes are always present,

generally of large size and touching each other in the medial line for more or less

of their length. Below the compound eyes lies a pair of large ocelli of peculiar

form, often being dumbbell-like or triangular with the broadest part near the

middle line. More anterior still is a simple organ which is spoken of as the

single ocellus,

In the head the epicranial suture can frequently be seen, and the labrum and

clypeus are well developed. The mouth parts themselves are cxserted and con-

form to the primitive type as exhibited in the more generalised of the higher

Trans. Roy. Soc. S.A., 62 (1), 22 July 1938

insects such as the cockroaches. The mandibles are simple in form, consisting

of a single sclerite furnished with a well-developed molar plate and several apical

teeth. These latter are often much worn by use and are renewed at each ecdysis.

In general the mandibles show much similarity to the corresponding organs in

some of the higher Crustacea. The superlinguae are well developed, each organ

consisting of two lobes and a vestigial palp. The maxillae are conspicuous organs

having a toothed lacinia and a hood-like galea and are furnished with a 7-seg-

mented palp. In the male scx the first and second segments often exhibit

specialised sensory organs. The labium or lower lip has a broad mentum and

submentum, a paired prementum and a 3-segmented palp. Both glossae and para-

glossae are present, each being divided into lobes. The terminal segment of the

labial palp is supplied apically with sensory sctae.

The thorax is comparatively large and considerably convex dorsally, some-

times being even gibbous. The coxal segments of the legs are large, and often

the second and third pairs carry movable stylets, which have been correlated by

some authorities with the exopodites of crustacean limbs. The tarsi are

3-segmented, ending in paired claws and sometimes having ventral scopulae

of hairs.

The abdomen has eleven segments, the last ending in the long tail filament,

while the penultimate segment carries the paired cerci. On some of the sternites

are one or two pairs of exsertile vesicles, and also a pair of stylcts. The median

sclerite of the sternites may be large and triangular or more or less completely

hidden by the coxal plates.

The genitalia are simple, usually consisting of one or two pairs of gona-

pophyses which, in the female sex, form the valves of a long ovipositor, and in

the male are short and accompanied by a short median penis.

Of the life-history of these insects little is known except in the European

genus Petrobius. In this there are at least six instars, each of which closely

resembles the adult except in size. ‘The first two instars, however, are entirely

scaleless and without the thoracic coxal stylets of the later stages. There also

appears to he a subimaginal instar in which the genitalia are developed but sexual

maturation is not attained.

CLASSIFICATION OF THE MACHILIDAE

The following three subfamilies are recognised, of which the first only is as

yet known to occur in Australia :-—

1. Abdominal segments all with median sternal sclerites almost if not quite invisible.

At most each abdominal sternite with only a single pair of exsertile vesicles.

Meinertellinae

Abdominal segments II-VII with relatively large and visible triangular median

sternal sclerites. 2

2. Only a single pair of exsertile vesicles on any one segment. Proaemachilinae

Some sternites with two pairs of exsertile vesicles. Machilinae

Subfamily MEINERTELLINAE

Two genera only, Allomachilis Silv. and Machiloides Silv. (= Nesomachilis

Till.) are, so far, known to occur in Australia, while but a single representative

of the latter is found in New Zealand. Careful search in the kinds of localities

indicated above may reveal other genera and species, and for this reason the

following key to the known genera of Machilidae is given :—

1. Exsertile vesicles present on sternites I-VII. 2

Exsertile vesicles only on sternites II-IV. Legs II and III with coxal stylets.

Paired ocelli triangular. Gen. Allomachilis Silv.

2. Coxal stylets on legs II and III. Paired ocelli transverse, elongate. Second scg-

ment of maxillary palp in male with subapical process and sensory setae or rods.

Gen. Machiloides Silv.

(= Nesomachilis Till.)

Coxal stylets only on leg III or wanting. 3

3. Coxal stylets on leg III. 4

Coxal stylets wanting on all legs. 6

4. Eyes large, much deeper than wide. Cerci slightly longer than body. Subapical

process of palp II of male not hook-like Gen. Megalopsobius Silv.

Eyes normal, wider than deep. 5

5. Coxal stylets on leg JIT reduced. Male gonapophyses absent.

Gen. Hypomachiloides Silv.

Coxal stylets on leg ITI normal. Gen. Machilontus Silv.

6. Male sex without tarsal scopulae. 8

Male sex with dense tarsal scopulae. 7

7. Tarsal scopulae present in both sexes. Gen. Meinertellus Silv.

Tarsal scopulae confined to the male. Gen. Meinertelloides Wom.

8. Paired ocelli not elongate, subrotund and almost touching lower margin of eyes.

Gen. Machilinus Silv.

Paired ocelli transverse. 9

9. Eyes large, deeper than wide. Paired occlli transversely oblique. Median sternal

sclerites almost invisible. Gen. Macropsontus Silv.

Eyes normal. Median sternal sclerites visible. Male gonapophyses present or not.

Gen. Machilellus Silv.

Genus ALLOMACHILIs Silv., 1904

Allomachilis froggatti Silv., 1904

Hitherto, this species was the only one recorded from Australia. It was

described in 1904 by Prof. F. Silvestri from specimens collected by the late Mr.

W. W. Froggatt on the coast of New South Wales. All the original specimens,

however, were females.

Through the kindness of Prof. G. E. Nicholls the writer was able, while

working at the University of Western Australia, in 1930, to examine about a

dozen specimens of a Machilid collected by Prof. Nicholls and Mr. K. C. Richard-

son at Herring Cove, Two-people Bay, near Albany, Western Australia, in

January, 1925. This material was labelled provisionally, “Allomachilis, sp. nov.,”

and again all the specimens were females. On re-examination it was possible

to definitely identify the specimens with Silvestri’s 4. froggatti.

While holidaying in the Albany district in January, 1932, an attempt was

made, with the aid of a friend acquainted with the district, to locate the spot

where Prof. Nicholls had obtained his specimens, in the hope of finding the

unknown male.

The habitat was found to be a small sandstone outcrop on the eastern end

of Herring Cove; all the rest of the coast thereabouts being granite. About half

a dozen specimens were secn, but owing to their extreme agility only two were

captured. Of these, one was lost on the way back to Perth, but the other, on

examination, proved to be a fully developed male. The following description of

this sex deals mainly with the points in which it differs from Silvestri’s descrip-

tion of the female :—

Description of Male—-Dimensions, eyes, paired ocelli, antennae, thoracic and

abdominal stylets and exsertile vesicles as in the female. Second segment of

maxillary palpi simple and without sensory organs. Penis short; gonapophyses

wanting.

Locality—Herring Cave, Two-people Bay, Western Australia, in January,

1932.

Remarks—This species also occurs in South Australia, where it has been

found by the writer at Marino Rocks and at Yvonne Bay, Kangaroo Island. It has

also been collected on Flinders Island, Bass Strait, Tasmania, by Mr. J. W. Evans.

Genus MAcuHiIvoives Silv.

= Nesomachilis Tillyard, 1924

In 1924 the late Dr. R. J. Tillyard erected the genus Nesomachilis for a

New Zealand species, N. maoricus, In his description and figures there appears

to be no characters by which the genus can be separated from Muachiloides of

Silvestri. That this is so has been confirmed by the writer, who, through the

courtesy of Dr. J. Millar, of the Cawthron Institute, Nelson, New Zealand, has

been able to re-cxamine Tillyard’s type material, as well as fresh material from

Nelson, kindly supplied by Mr. J. W. Evans.

About 1934 Dr. Tillyard informed me that he was making a biological study

of a species of Machilid which he had obtained from the neighbourhood of

Brisbane. Upon request he kindly sent a number of specimens for specific

determination, Study of this material showed that, while closely allicd to the

New Zealand form, it belonged to a new and distinct species.

In the collections of the South Australian Museum was a single carded

Machilid labelled “Stanwell Park, New South Wales,” which had possibly been

‘collected by A. M. Lea many years ago. On dismounting and dissecting, this

specimen was found to be a female of the Brisbane specics. Two other females,

collected by Miss M. E. Fuller at Sydney in 1933, are also of the same form.

Description of the new species is as follows :—

Machiloides australicus n. sp.

(Text fig. A-E)

Length of body to 7 mm. Colour in spirit brownish, in life probably dark

fuscous. Antennae thin, except the basal segments, reaching to two-thirds length

of body; basal segment twice as long as broad, distal segments with 9-10 sub-

divisions. LEyes large, round, touching medially for two-thirds of their depth.

Paired ocelli pear-shaped, transverse, widely separated medially. Labial palpi

normal, apical segment with few but large setac or rods (fig. A-B). Maxillary

Machiloides australicus n. sp. (Male)

A, apical segment of labial palp; B, a single sensory seta from apex of above;

C, first and second segment of maxillary palp; D, leg I; E, leg HI.

palpi with the usual triangular and bulbous processes on segment I; II in the

male with a subapical bent parallel-sided lobe, below which are a number of short,

blunt, black rods; below these rods are some black-pointed setae which extend

right across the segment. This structure somewhat resembles that described by

Evans in 1927 for M. maoricus (Till.), but in the latter species the rods are

placed in a distinct pocket formed by the subapical lobe and do not lie free as in

the new species (fig. E). The remaining segments of the maxillary palpi are

simple. The relative lengths of the segments of the maxillary palpi are :—male,

17: 20: 23: 20: 32: 25: 20; female, 10: 15: 13: 13: 20: 15: 15;

lacinia shorter than galea. Mandibles normal with toothed apex and well

developed molar plate.

Thorax moderately arched; legs I strong and somewhat raptorial, the

femora and tibia being swollen inwardly, II and III longer and thinner with well

developed stylets on coxae,

Abdominal segments with median sternal sclerites practically invisible,

II-VII with a single pair of exsertile vesicles, I]-IX with stylets, those on IX

twice as long as those on VIII and with the apical seta two-thirds of their length.

Median tail appendage two-thirds of body length, cerci rather shorter.

Male: penis short, gonapophyses absent.

Female: ovipositor short, annulated, scarcely reaching tip of ninth stylet.

The whole body is heavily scaled, the scales arranged in the manner described

by Evans for M. maoricus (Till).

Remarks—tIn the original description of M, maoricus the exsertile vesicles

are given as present on sternites ]-1X. This is a printer’s error, for in no species

of Machilidae so far known do these organs occur beyond sternite VII. ‘The

new species described above is a rare and apparently very local one. It appears

to be an inland and not coastal form and should be searched for in stony woods.

AN EXAMINATION OF THE BROWN COAL OF MOORLANDS

PART II

BY W. TERNENT COOKE

Summary

The results presented in this paper serve as an extension of the work on Moorlands coal previously

&en in this journal (Trans. Roy. Soc. S. Aust., 1937, 61, 80).

Carbonization-Shaw (6) has made thorough carbonization tests with a charge of 97 lbs. of the coal,

followed by an examination of the products. He used the apparatus of the Geological Survey of

Victoria, following the procedure applied to the examination of the brown coals of that State.

AN EXAMINATION OF THE BROWN COAL OF MOORLANDS

PART II

By W. Ternent Cooxe, D.Sc., AVA.C.TI.

[Read 11 November 1937]

The results presented in this paper serve as an extension of the work on

Moorlands coal previously given in this journal (Trans. Roy, Soc. S. Aust., 1937,

61, 80).

Carbonization—Shaw (6) has made thorough carbonization tests with a

charge of 97 Ibs. of the coal, followed by an examination of the products. He

used the apparatus of the Geological Survey of Victoria, following the procedure

applied to the examination of the brown coals of that State.

For the sake of comparison, tests have been made with the “Fischer”

aluminium retort, an apparatus of semi-official status, using 50-gramme samples.

The coal, as distilled, contained 16% moisture. Results are tabulated in Table I.

During the tests samples of the gas were collected over varying intervals of

temperature, and analysed for their content of carbon dioxide and sulphuretted

hydrogen, The data relative to these gases have been combined and plotted as a

curve. The large content of sulphuretted hydrogen is noteworthy, and

suggests possibilities of recovering some of the sulphur content of the coal.

Similar results have been obtained by Bone (7) with a sample of South Austra-

lian coal, doubtless from Moorlands.

The Char—The residue from the distillation is a finely divided black powder.

Analyses gave carbon, 64°85%; hydrogen, 2°45%; ash, 24°30%. The ash

contains 8'54% of sulphur as sulphate, equivalent to 2°08% of the 3°49% total

sulphur content of the coal (with 16% moisture), leaving 1°41% “volatile”

sulphur. The analysis then becomes: carbon, 64:85% ; hydrogen, 2°45%; ash,

24-30% ; sulphur, 1-41%. Difference (oxygen and nitrogen), 6°99%.

The ash of the char contains also 26°5% insoluble in acid, and 26°7% of

iron, alumina, titania, besides the 8°54% of sulphate.

Nitrogen Content—A previously found value for nitrogen (1) is 0°4%.

The author’s sample gave 0°45% for the moisture-free coal. This low content

is usual with lignites. Experiments showed that none of the nitrogen is extract-

able with dilute acid.

Chlorine Content--The percentage found for the bulk coal was 0°035%.

Carbonate Content—Calculated as CO,, the value 0°2% was found.

Calorific Value—The official figure (2) given is 7,548 B.T.U. per pound.

Taking the moisture content as given (2) 14°3%, one obtains 8,808 B.T.U. for

the dry coal. Further, taking the value for sulphur 3:7% for moist, or 4°32%

for dry coal, and applying Parr’s formula, (3), the value 12,450 B.T.U. is obtained

for “unit” coal. The corresponding values for Noarlunga (4), and Balaklava~-

Inkerman coal (5), are, respectively, 12,655 and 12,430.

True Mineral. Content—King and others (8) have deduced a formula for

arriving at an estimation of the true mineral content of a coal from a knowledge

Trans. Roy. Soc, S.A., 62 (1), 22 July 1938

of the amount and composition of the “ash” and other analytical data. The

values of certain factors in King’s formula are based on a study of black coals,

English mainly, but these factors should in general be applicable to brown coals.

Thus the water content of the air dried shale associated with the black coal has

an average value of 8%; the black clay found above the Moorlands clay has a

water content of 61% (9). King’s formula is :—

Mineral matter = 1:09% ash +- 0°5% pyritic sulphur + 0:8% CO,

+ SO, in coal + 0°5% Cl — 1:1 SO, in ash.

Inserting the following percentage figures:—15:°9% ash, 0°91% pyritic

sulphur, 0°2% CO,, 0°965% SO, in coal, 0°035% Cl, 2°81% SO, in ash, the final

value 15-84% is obtained, almost identical with that of the “ash.”

Erdmann and Dolch also have given a formula for calculating the true mineral

content (10). This formula gives a value of 15-6%, which again differs but

slightly from that of the “ash.”

King has also given formulz for calculating the composition of the actual

coal substance, te., on the moisture and ash-free basis. Using the values already

found for the bulk sample (9), the calculated composition is carbon, 65:49% ;

hydrogen, 4:80% ; nitrogen, 0°53% ; sulphur, 3-45% ; oxygen, 25-73%.

Effect of Moderate Preheating on the Coal—It is known that a slight

improvement in the quality of a lignite can be effected by heating to a tempera-

ture short of active decomposition; some combined oxygen is driven off as water

and carbon dioxide. The effect was studied by heating portions of air-dried coal,

containing about 13% of moisture, in a stream of dry, oxygen-free nitrogen.

Heating was in two stages, first to about 120° C., and then to about 230° C.; the

water and carbon dioxide formed over each temperature interval were collected

and weighed, and the loss in weight of the coal found. Over the lower interval

the loss is almost entirely hygroscopic water; over the higher, the carbon dioxide

is about one-half of the water. There is no appreciable amount of other volatile

products, as shown by the concordance between the sum of the weights of the

collected products and the loss in weight of the coal. Taking the average figures

of three typical experiments, the weights of volatile products over the two ranges

of temperature are, respectively —carbon dioxide, 0°4% and 1°8% ; water, 13-3%

and 3°2%, giving a total of 18°7%, of which 5% is evolved after loss of hygro-

scopic water. The total loss in weight of the coal was also 18°7%. At about

230° C. there is evidence of the beginning of more pronounced decomposition—

the characteristic smell of heated brown coal is noticeable. ‘Che preheated product

has the composition:—C. 56°70%, H.4:02%, O.18-12%, S.4-32%, and ash

16°84%. That a slight improvement has been effected is shown by a comparison

of the composition of the preheated with that of the original coal, both calculated

on an ash and moisture-free basis (original coal in brackets) :—C. 68-19%

(65-55%), H. 4°83% (498%), O. 21:79% (24-60%), S. 519% (487%).

ON THE OCCURRENCE OF A FOSSIL PENGUIN IN MIOCENE BEDS IN

SOUTH AUSTRALIA

BY H. H. FINLAYSON

Summary

The specimen herein noticed was found by Mr. W. Burdett in the cliffs above Christie's Beach on

the east shore of St. Vincent Gulf, at a point about 16 miles south of Adelaide, South Australia. The

site has been examined by the late Professor Walter Howchin, who has pronounced the beds to be

of undoubted Miocene age, and it is satisfactory that this, the first record of the tertiary

Spheniscidae in Australia, should be free from the chronological uncertainties which attach to some

other of the occurrences of the family elsewhere.

ON THE OCCURRENCE OF A FOSSIL PENGUIN IN MIOCENE BEDS

IN SOUTH AUSTRALIA

By H. H. FINLAyson

[Read 14 April 1938]

The specimen herein noticed was found by Mr. W. Burdett in the cliffs

above Christie’s Beach on the cast shore of St. Vincent Gulf, at a point about

16 miles south of Adelaide, South Australia. The site has been examined by the

late Professor Walter Howchin, who has pronounced the beds to be of undoubted

Miocene age, and it is satisfactory that this, the first record of the tertiary

Spheniscidae in Australia, should be free from the chronological uncertainties

which attach to some other of the occurrences of the family elsewhere.

The bone (pl. i, fig. A-B), which is a left humerus, is held in a friable

matrix of calcareous grit. Originally only the proximal surface of the head and

the outer surface of the shaft were exposed, but by careful flakeing with a steel

point, all its margins have been satisfactorily developed without damage, except

in the region of the sesamoid articulation at the distal extremity. Here the matrix

proved harder than elsewhere and, as the bone was weakened by a transverse

fracture, little pressure from a tool could be applied and some slight indefiniteness

of outline has been allowed to persist.

The bone is in excellent preservation and is complete except for the tuberculum

externum, which has been broken away anciently. The outer exposed layers of the

cortex have become somewhat chalky by weathering, but the main mass of the

shaft is strongly mineralized and has a dense flinty texture. Although the shaft

shows four transverse fracture lines, there is no evidence, of crushing or distortion.

In addition to the humerus, some fractured laminae probably derived from

a radius, and another fragment showing a porous cancellated structure, are also

present.

Lowe (1), in his excellent paper on the primitive characters of penguins,

reviews the fossil humeri from Seymour Island, figured and described by

Wiman (2), and singles out five structural characters, of functional significance,

which distinguish the humeri of these and other tertiary penguins from those of

recent species.“ In describing the present specimen, therefore, it seems

expedient to concentrate upon these points, rather than to embark on a detailed

account of its morphology.

1. A more pronounced inturning of the articular surface of the head of

the humerus, than in recent species, was claimed by Wiman. This was doubtfully

conceded by Lowe, who considered that in the fossil birds it might be correlated

with less freedom of rotary movement within the joint.

©) With the partial exception of the primitive Eudyptula

Trans. Roy. Soc. S.A., 62 (1), 22 July 1938

In the present specimen the humeral head is somewhat abraded, the can-

cellated tissue being exposed, and its dimensions possibly somewhat reduced.

Making full allowance for this, however, it still supports Wiman’s claim. In a

posterior view, the onsetting of the head to the shaft is appreciably more axial

than in Aptenodytes forsteri, for example. In the present fossil the long axis of the

shaft passes almost through the vertex in this aspect of the head, whereas in

A. forsteri the vertex is displaced about 6° mesiad. (See pl. i, fig. B.)

2. The smaller size of the fossa pneumatica (f. subtrochanterica) in the

tertiary species.

This is strikingly illustrated in the present bone, both as regards width and

capacity, though some allowance must be made for attrition in the fossil. More-

over the cavity is simple, without or at most with slight indications of the

secondary cavity on the internal wall, as in Aptenodytes forsteri. The total

capacity of the fossa (as preserved) is just one quarter that of the cavity in a

rather small A. forstert.

3. In the tertiary humeri the trochlea ulnaris and trochlea radialis occupy

sites upon the lower angle of the preaxial border, rather than upon the distal

margin, and their articular surfaces face outwards rather than downwards as

in the recent genera. ‘This leads to the articulation of the antibrachium at a smaller

angle with the humerus than in recent penguins. Lowe interprets this as evidence:

of inferior natatory specialization.

In the present fossil the facets of the two condyles are confluent, as in the

humerus attributed by Hector (3), to Palaceudyptes antarcticus Huxley (4),.

but the site of the conjoined surface is exactly as in Wiman’s humerus No. 3,

as refigured by Lowe (loc. cit.).

4. The preaxial border is without an angular prominence and the maximum

width of the bone is towards the proximal rather than the distal extremity. Both

conditions are clearly exhibited by the fossil.

5. Wiman (loc. cit.) suggested that in the Seymour Island humeri the

entepicondylar process bearing the sesamoid grooves was less produced than in

recent penguins. Lowe considered that the differences observable were due to abra-

sion of the fossils. But it is quite clear in Hector’s figure of the Nelson (N.Z.}

humerus, and somewhat less so in the present specimen, that the angle is much less

prominent than in Lowe’s hypothetical outline (loc. cit., fig. 12a), or in the modern

Aptenodytes, though it may find a parallel perhaps in other modern genera.

While possession of the above listed structural features satisfactorily allies

the South Australian fossil with others of like geological age from widely

sundered localities in the Southern Hemisphere, the question of generic identifica-

tion remains a difficult one; partly owing to the impossibility of instituting com-

parisons with forms founded on bones other than humeri, but still more to the

uncertainties which, in the Spheniscidae, surround the diagnostic value of the bone.

The activities of Ameghino, Moreno, Mercerat, and Wiman (loc. cit.) have

greatly expanded the list of names of fossil penguins, so that it now includes

35 species referred to 22 genera (5-6). The form which is geographically nearest

to the site of the present find is that which was first described, Palageudyptes

antarcticus Huxley, 1859 (loc. cit.), from beds of similar age in New Zealand.

Huxley founded the species on a tarsometatarsus only, but in 1871 Hector obtained

other bones from the same horizon as the first find, which he ascribed to the same

species. ‘he second find included an almost perfect humerus, which is excellently

figured (loc. cil.) pl. viii, figs. 1:2:3). Comparison of the South Australian speci-

men with this figure reveals a very close correspondence both in dimensions and

structural detail, and the few points of difference are of such kind as to be readily

accounted for by differing age of the individual birds, and varying degrees of ero-

sion of the fossils, which is considerably greater in the South Australian specimen.

While such an agreement in macroscopical features might be regarded as a

valid identification in Palaeontology, it cannot be overlooked that in the present

case there are other considcrations, both morphological and zoogeographical,

which introduce an clement of doubt, and these may be briefly noted.

1. While the tertiary genera may be satisfactorily distinguished from

the recent by osteological characters, contemporary recent genera show amongst

themselves a much smaller range of diversity in such structural points. Both

Watson (7) and Pycraft (8) have unequivocally stated that in some recent

genera, which are markedly distinct in external characters and habits, the humeri

may be virtually identical, A similar state of things in the tertiary forms, while

fess probable perhaps, is still possible, and the birds which became fossilized at

Nelson and Christie’s Beach, respectively, may have shown much greater total

differences than can now be found in their humeri.

2. The New Zealand and Australian finds are located in zoological sub-

regions of marked and long-established distinctness ; a distinctness exemplified by

a very large proportion of both the fossil and recent avifauna of the two.

In the existing penguins, the pelagic habit has been so perfected that voyages

of many hundreds of miles are annually made by the migratory species, and on

oceasion these normal distances are enormously exceeded, as is shown by the

records of extralimital occurrences of several species, and the accounts of eye-

witnesses who have observed the birds in the open oceans (9).

Obviously the existence of such pelagic habits in the tertiary penguins would

tend to nullify the zoogeographical distinction by providing the means (though not

necessarily the incentive) for transgressing the boundaries of the two subregions.

3, However, in the case of the tertiary penguins of the Antarctic Archi-

pelago, which lived under temperate or even subtropical climatic conditions, Lowe

considers there is evidence in the tarsometatarsus and humerus of superior

terrestrial and inferior aquatic specialization, respectively. This suggests the

probability that a comparatively sedentary coast-frequenting habit then prevailed

(which has persisted to some extent in one existing species of Aptenodytes), and

that the truly pelagic, deep sea-going habit of some of the modern species was a

much later accomplishment, acquired in response to increasing severity of climatic

Plate I

conditions imposed by later glaciation. In this connection, it is significant that

in several existing species it is only the more southerly colonies which undergo

an annual migration.

4. That all conclusions as to relationship drawn from such considerations

as are set out in (2-3) are fallible, unless the original centre of dispersal of the

forms is known, seems to be indicated by the presence of Eudyptula minor in

both New Zealand and South Australian waters; Eudyptula being the most

primitive of the existing genera, and that which in its coast-wise and relatively

sedentary habit seems least adapted to bridge the gap between the two areas.

In view of the uncertainty in the value of the evidence derived from the

humerus and the conflict in the theoretical considerations bearing on distribution,

I have not felt justified in applying a name to the fossil. As the chief object of

the present note is to record the occurrence, it will suffice to point out again its

apparently close relation to Palaeeudyptes antarcticus Hux.

In conclusion I have to thank Mr. W. Burdett for an indefinite loan of the

fossil for purposes of description; and Messrs. J. Sutton and H. Condon, of the

Department of Ornithology of the South Australian Museum, who have made

available material for comparison and assisted in other ways; and the authorities

of the Public Library of Melbourne, and the Australian Museum, Sydney, for

timely Joan of books.

A LEGEND OF THE TANGANEKALD, COORONG, SOUTH AUSTRALIA

BY NORMAN B. TINDALE

Summary

The traditions and beliefs of the Tangane people of the Coorong, in South Australia, seem to belong

to several cultural strata. Some stories relate to the behaviour and adventures of heroic ancestral

beings "who made the country, and prepared it for the present natives." Such beliefs may deal with

the life-story of Ngurunderi ['njurunderi] and other superhuman man-like beings, collectively called

[‘maldawuli]. Other stories are centred around the behaviour of numerous [qaitje] or totemic beings,

most of whom are considered to be birds (e.g., crow, eagle, silver gull, pelican), although when the

events of the stories are taking place they usually are manifesting more of their human attributes

than of their bird-like ones. A further stratum of stories relates to individuals of unequivocably

human origin, who possess [njaitje] like present-day folk and about whom there is no suggestion of

an alternative or subsequent translation into the [njaitje] form.

PRUPE AND KOROMARANGE

A LEGEND OF THE TANGANEKALD, COORONG, SOUTH AUSTRALIA

By Norman B. TInpALE, B.Sc.

[Read 14 April 1938]

Pate IT

The traditions and beliefs of the Tangane people of the Coorong, in South

Australia, seem to belong to several cultural strata. Some stories relate to the

behaviour and adventures of heroic ancestral beings “who made the country, and

prepared it for the present natives.” Such beliefs may deal with the life-story

of Ngurunderi [‘gurunderi] and other superhuman man-like beings, collectively

called [’maldawuli]. Other stories are centred around the behaviour of numerous

[yaitje] or tolemic beings, most of whom are considered to be birds (e.g., crow,

eagle, silver gull, pelican), although when the events of the stories are taking

place they usually are manifesting more of their human attributes than of their

bird-like ones. A further stratum of stories relates to individuals of unequi-

vocably human origin, who possess [naitje] like present-day folk and about

whom there is no suggestion of an alternative or subsequent translation into the

[yaitje] form.

The Prupe story belongs to the last-named category. Its elements are

simple :—

Cannibalistic behaviour of an aged blind woman.

The good grandmother and her bad sister.

Exchange of feeble eyes for good.

The leaking vessel which she strives to fill.

Destruction of the bad woman and her camp by a sudden catastrophe.

The site of the present story is connected with a strange circular depression

about thirty metres in diameter and ten deep, of unexplained origin, situated near

McGrath Flat homestead, on Section 24, Hundred of Glyde.

According to one suggestion this may be a meteorite crater; its form being

such as to encourage this view. However, there is no evidence of the presence

of meteoric material on the surface near the supposed crater, and the suggestion

cannot be accepted until confirmation is forthcoming; nevertheless, definite asso-

ciation exists between such a depression and a story of a catastrophic event

accompanied by a blaze of fire. It seems possible that the story, in its present

form, may be the dramatisation of an actual meteorite fall at this spot.

The story was obtained by the writer several years ago, and the phonetic

rendering of the vowels is somewhat broader than in more recent work.

Trans. Roy. Soc. S.A,, 62 (1), 22 July 1938

The phonetic system employed is that adopted at the University of Adelaide

and described by the writer in 1935.

Differences between the series n d t, and the interdentals, n d t, are well

marked in this language. In the text the sounds of the second series are

denoted by black letter type, while on the sketch map they are indicated by

a vertical black line under the letter. In the interdental series the sounds

are made with the tongue protruding about 0°5 centimetre between the teeth.

NORTHERN PORTION OF THE HUNDRED or GLYDE COORONG, SOUTH AUSTRALIA

Fig. 1

This feature has been noticed previously by the writer in Jaraldekald texts.

(1937), and since by Miss McConnell among the peoples of Cape Yorke Peninsula,

and by Capell (1937) among the Kurnu.

The following short story is the first Tanganekald prose text to be published ;

some songs were given, however, in a recent paper (Tindale, 1937). Prose texts

in several other languages of the South-East of South Australia await collation

and publication.

The earliest indication of any element of this story seems to be the bare

mention in Meyer’s Raminjeri vocabulary (1843, p. 57) that brupe means “bad

or old”; the present story gives a fuller meaning to the word.

In several places the translations suggested by the informant do not give the

exact sense. With larger vocabularies and a more detailed gathering of details

of grammar, etc., this may be remedied. Where an informant has almost ceased

to use his own language, owing to Jack of fellows, it is not surprising when he

finds difficulty in explaining his meaning in a foreign tongue, even when it has

been known to him since early manhood.

The accompanying figure (pl. ii) shows Milerum, narrator of the legend

drinking from a human skull vessel [’merikin] similar to the one used by the old

woman of this story. Such vessels are made waterproof by being plastered with

a mixture of red ochre and oil of the emu or whale.

A sketch map shows the northern half of the Hundred of Glyde and records

the positions of places mentioned in this story. Upon it are also inscribed the

names of all other known native place-names in the area, together with some

‘Tangane [’keinari] or clan boundaries. This sketch map is a portion of one of

the many “hundred” maps covering the South-East of South Australia, upon

which have been marked about 1,500 significant native place-names of the

Tanganekald and adjoining tribes. When published in full they will give a com-

prehensive idea of the nomenclature and geographical knowledge of members

of a typical South Australian tribe. The names are of necessity crowded, but if

they are studied in conjunction with the Hundred map, a close approximation to

the location will be obtained.

When recording this information in the field informants frequently had

cause to lament the physiographic changes which have been wrought by the

clearing of sandy ground, the stocking of the Coorong with sheep and cattle,

and its invasion by rabbits, leading to rapid drifting and alteration of old fixed

sandhills, lookouts and other landmarks. As one old man expressed it: “Our

[’maldazeuli] told us, long, long ago, to ‘beware of ants.’ White men must be

the ‘ants’ he spoke of, for they have eaten away all my people, my herbs, my

game, and even my sandhills.”

The Coorong is an example, on a gigantic scale, of a lagoon locked behind

an offshore bar which extends from Port Flliot in the north to beyond Kingston

in the south, a distance of well over one hundred and forty miles. ‘This bar and

lagoon was preceded by an earlier onc, the remains of which form the landward

shore of the present-day Coorong lagoon. This older dune series, the Woakwine

Terrace, was preceded by similar still earlier physiographic features, which

dominate the country further inland in alternating belts of dune and swale, for

as much as sixty miles.

The second sketch map gives a generalised view of a portion of the Coorong

to illustrate six descriptive terms used by Tanganekald people.

To Tangane folk the grass-covered sandy limestone slopes of the Woakwine

Terrace, forming the landward shore of the Coorong, were known as [’tengi].

Along this strip were many favourite camping places, all of them exposed in some

degree to the attacks of strangers from out of the inland scrub. Inland from

[‘tengi] was [/lerami], mile upon mile of mallee and swampland, fit only for

hunting. [’Lerami] was literally the “back country”.

The shallow Coorong lagoon itself was [’pandalapi], source of the fish which

formed the staple food of their economic system. [’Parinari], the seaward

shore of the lagoon provided the ideal home of the Tangane. Here, with their

backs to the ocean, a high fixed dune to serve as lookout and a clear view in the

GREAT SOUTHERNOCEAN

Fig. 2

landward direction, they felt safe from their enemies. Behind them was

[’natuni’juru], a continuous belt of dunes, from one to three miles wide and a

hundred miles long, separating them from [‘jurli], the ocean beach. In the

season their womenfolk repaired daily to [‘jurli] to gather cockles, the Donax

deltoides whose remains today are strewn thickly on every foot of old dune from

Middleton to Kingston.

These native terms appear so often in Tangane description and conversa-

tion that it is desirable that they should be on record. Lerami, Tengi, and other

terms are so euphonious, and supply such a want that they might well be used

by the geographer and physiographer as names for these outstandingly interest-

ing features of the South-East of our State.

1. Koromarange feared to allow Prupe to come down to her lest she find the child

and eat it or exchange eyes with it.

2. Prupe noticed that K. had started to bring fish up to her; never done this

before, she was suspicious. She said, “Once upon a time I used to go down

to my sister.”

3. On one occasion when Prupe went down K. rushed out of her hut to give

her fish.

4, P. pretended that she was K. The word-for-word translation is here doubtful.

5. K. arrived soon after, as P. was preparing to exchange her bad eyes for

those of the child.

6. K. pretended she was tired and sent P. for water. She pierced a hole in

the human skull water-dish so that it would leak.

7. P. baled out water; the skull leaked; she dipped again and again, finally put

her finger in the hole. While she was away K. made a snare to trap her.

P found she had been tricked, rushed out of the hut; was snared.

8. P. kicked the fire, causing a great hole in the ground; she burnt herself to

death. This place is now a large cavity in the ground to the north of the

McGrath Flat homestead, on Section 24, Hundred of Glyde. The original

text here was not completely translated.

9. K. fled across the Coorong with the child and watched the fire from the top

of the sandhill called [’Jungu’run bar. ]

A GENERAL RENDERING OF THE STORY

Prupe and Koromarange were two Marntandi clan sisters who lived near

McGrath Flat on [tengi|, i.e., the landward shore of the Coorong. They had the

same [yaitje] totem. One lived at a place just behind the present McGrath home-

stead, called [Prupa’ynawand]; the narrator was first shown the place when he

was a boy. It is a big hole in the ground. The other sister lived a mile away to

the west along the Coorong, on Rabbit Island, at a place called [’Koro’maray’gul ]

or [’Kuruma’rayk].

At first Prupe had good eyesight, but she began to go blind and became a

very savage person, who ate all the children in the country. Her sister Koro-

marange had a grand-daughter named [’Koa’kangi] who, owing to the depreda-

tions of Prupe, was almost the last child left in the district. To prevent P.

coming down to her camp, K. began suddenly to take her offerings of fish, food,

herbs and grasses. P. became suspicious.

“Once upon a time I used to go down to K. That woman is very good to

me. I will go down and see what she is doing. I feel she has a grand-daughter

down there.”

On one oceasion she went across to [’Koro’maran’gul}], K. saw her and

rushed out of the camp with a present of fish. As time went on Prupe lost her

sight altogether. She wanted more than ever to catch the child.

By exchanging eyes with it she would be able to sce once more. She came

down again; K. was away, fishing with nets. The little girl cried out for water.

P. gave her water, then seized her and escaped to her own camp at [’Prupa’na-

wand]. On her return K, missed the child, and tracked P. to her camp. She

arrived just as her sister was about to operate on the eyes of the child. She

pretended to be pleased that P. had found the infant and asked P. to fetch water

for it, as she (K.) was tired from fishing. With a spear she poked a hole in a

human skull water-dish and handed it to her sister. The dish leaked so badly

that P. was a long time obtaining the water. Meanwhile K. prepared a snare

and gave a deceiving cry, pleading for water. P. hastened into her camp with

the water. She found K. had fled with the child and she had been tricked. She

rushed out, was snared and, in her excitement kicked the fire; it blazed up, burnt

her and the camp she was in. A great pit took the place of her camp. K. fled

back to her camp and then away over the Coorong lagoon, by the shallow water-

crossing to [’Jungu’run’bar], a high scrub-covered hill on [jurli], i.e., on the

ocean beach side. She looked back and saw the big fire blaze up as her evil sister

perished.

LARVAL TREMATODES FROM AUSTRALIAN TERRESTRIAL AND

FRESHWATER MOLLUSCS

BY T. HARVEY JOHNSTON AND E. R. CLELAND

Summary

Specimens of the terrestrial gastropod, Succinea australis (Ferussac), collected by Mr. F. Jaensch at

Elwomple, near Tailem Bend, on June 24, 1937, were examined a month later, and in one a large

pulsating sac which contracted rhythmically for some hours, was found alongside the liver. Upon

dissection the main part of the sporocyst to which the sac was attached was uncovered. It consisted

of a central portion from which arose about six juvenile pulsating structures and numerous knob-

like, club-like and finger-like projections, many of the latter being of considerable length and

ramifying for some distance through the tissues of the snail.

Leucochloridium australiense, n. sp.

Specimens of the terrestrial gastropod, Sxccimea australis (Ferussac),

collected by Mr. F. Jaensch at Elwomple, near Tailem Bend, on June 24, 1937,

were examined a month later, and in one a large pulsating sac which contracted

rhythmically for some hours, was found alongside the liver. Upon dissection the

main part of the sporocyst to which the sac was attached was uncovered. It

consisted of a central portion from which arose about six juvenile pulsating struc-

tures and numerous knob-like, club-like and finger-like projections, many of the

latter being of considerable length and ramifying for some distance through the

tissues of the snail.

‘The main part of the sac (fig. 3) was white with distally-situated coloured

bands, separated by slight constrictions. The most proximal of these bands was

‘an incomplete brown ring, the second and third were complete brown bands, the

fourth a pale shade of green, the fifth a complete brown ring, the sixth an

incomplete brown band, and the tip of the sac was brown. Each of these rings

was separated by a colourless band, in the centre of which (except between the

fifth, sixth, and tip of the sac) was an opaque white line at the point of

constriction.

THE CERCARIAEUM

About twenty fully developed cercariaea were found in the large pulsating

sac. Each was enclosed within a thick gelatinous sheath (fig. 2) interrupted at

both the anterior and ventral suckers. In the outer part of the sheath faint

concentric and radial lines were seen.

Each cercariaeum (figs. 1, 2, 4) was capable of much contraction and expan-

sion, and a typical one was 616 » long and 347 uw broad when contracted, and 308 p»

broad when extended. The almost circular anterior sucker, which was surrounded

by an elevated margin more pronounced dorsally, measured 193 » across, and the

mouth was subterminal on its ventral surface just below the tip. A powerful,

almost circular, pharynx, 69 » long, was present, and from its dorsal aspect arose

a very short oesophagus. This divided almost immediately to form the two

intestinal caeca which arched upwards and outwards, and then passed backwards

on either side of the ventral sucker to the level of the genital pore.

Trans. Roy. Soc. §.A., 62 (1), 22 July 1938

The ventral sucker lying in the anterior part of the second half of the body

was 154 in diameter. The anterior sucker, pharynx and ventral sucker (figs. 11,

12, 20) were formed of radiating muscle fibres associated with large vacuolate

myoblasts with prominent nuclei. Circular sphincter-l-ke and longitudinal to

oblique muscle fibres were present just beneath the cuticle, while internally to

the radial fibres they were most strongiy developed. At the junction of the anterior

sucker and pharynx the circular fibres were much more numerous, and at the

rim of the two suckers were grouped io form sphincters.

The intestine was lined by cuticle and cuboidal cells, and beyond the latter

a few circular muscle fibres.

The general body surface was covered with a thick cuticle, but no trace of

cilia was seen, though Magath (1920) and Zeller (1874) reported their presence

in other species. Underlying the cuticle were circular, longitudinal and oblique

muscle fibres supported by large connective-tissue cells (fig. 15). Scattered

muscle fibres were seen throughout the body.

The nervous system (fig. 11) was typical and consisted of two lateral brain

masses, one on either side of the anterior sucker and pharynx and connected

dorsally by commissures. A large ventral nerve could be traced backwards on

each side, and the root of each narrow dorsal nerve was seen. The anterior

sucker was supplied by nerves from the brain.

Sense cells (figs. 13, 14, 20) were present on the surface of both suckers

and an occasional minute one was scen in the cuticle of the body surface in the

level of the pharynx. They were specially prevalent at the edge of the mouth

and varied considerably in size, the largest being at the base of the anterior sucker

immediately before its junction with the pharynx. They were cither stalked or

sessile, and consisted of a central clear parenchymatous part (fig. 14), in which

was embedded the nerve fibrils, the whole surrounded by a substance having the

consistency and colour of the cuticle. Dorsally and laterally from the pharynx

a small number of cclls similar to these in size and structure and staining pro-

perties were seen embedded in the parenchyma, but it is difficult to account for

their function in such a situation.

REPRODUCTIVE SYSTEM

The two oval testes were diagonally placed, the anterior on the right-hand

side (as viewed through a compound microscope) a little distance behind the

ventral sucker; the posterior slightly dorsal to it but on the left-hand side. Above

the posterior testis and slightly dorsal and median to it was the oval ovary, the

three gonads thus forming a triangle (figs. 1,4). Jn some specimens the ovary

was found lying slightly in front of the anterior margin of the anterior testis.

From the posterior testis the vas efferens (fig. 17) passed obliquely upwards

ventral to the ovary and was joined by the shorter duct from the anterior testis.

From this point the vas deferens (figs. 8, 16) travelled backwards, then turned

sharply dorsally and passed through an undifferentiated cell mass to open at the

\ SE ae

gonopore on the dorsal side of the animal (figs. 6, 19, 20) a short distance from

the posterior end, No seminal vesicle or true cirrus could be seen. The undifferen-

tiated cell mass (figs. 1, 4, 6, 19, 20) near the gonopore was large and sur-

rounded the end parts of the uterus and of the vas deferens, and thus could not

be described at this stage as a cirrus sac. It gradually tapered ventrally and

anteriorly away from the gonopore and then became separated into two parts,

one of which surrounded the vas deferens and the other the uterus.

The short oviduct (fig. 10) travelled towards the mid-line, where it was

joined by Laurer’s canal (figs. 7, 8, 9, 19, 20), which passed posteriorly to enter

the excretory canal just before the latter reached the excretory pore. Magath

(1920, 109, 111) reported that a similar condition was present in L. prablematt-

cum, and was described by Looss (1899) for L. insigne. Near the junction of

Laurer’s canal with the oviduct was a slightly swollen part of the canal, probably

the anlage of the fecundarium, The oviduct, after its junction with Laurer’s

canal, turned ventrally and was then joined by a very short vitelline duct (figs. 8,

9) which passed backwards to become widened into a small reservoir receiving

the two yolk ducts. The latter ducts curved ventrally and anteriorly to the

slightly developed yolk glands lying laterally from the intestinal caeca. Surround-

ing the oviduct, yolk reservoir and fecundarium was a large mass of undifferen-

tiated tissue, the albumen gland (figs. 1, 4, 7-10).

After its junction with the yolk duct, the oviduct continued to the mid-

ventral line, where it passed forwards into the ascending uterus (figs. 8, 9).

This travelled upwards and outwards on the inner side of the anterior testis,

formed a loop around the dorsal portion of the ventral sucker (figs. 1, 4) and

descended on the other side, passing gradually towards the median line until,

just behind the sucker, it lay alongside its ascending branch. It then proceeded

posteriorly to the level of the gonopore, turned sharply dorsally, became asso-

ciated with the tissue of the undifferentiated cell mass, and joined the vas deferens

immediately before the latter opened at the gonopore.

EXxcRETORY SYSTEM

The excretory pore (fig. 5) was on the dorsal surface immediately above

the genital opening, and led into a small rounded excretory bladder (fig. 7). The

latter received Lauret’s canal dorsally (figs. 4, 7, 20), while laterally it gave rise

to two main collecting tubes (fig. 6) which passed upwards, external to the

intestinal caeca, to well beyond the base of the anterior sucker. Here these

canals bent backwards until they reached the level of the posterior region of the

sucker, where they became dilated just before giving rise each to an anterior

and a posterior collecting tubule.

The anterior tubule passed forwards and, in the region of the ventral sucker,

gave rise to a dorsal branch and a short ventral branch which appeared to join

the main ascending tube; the main stem then continued to the level of the

pharynx, where it divided into three branches; one of these passed dorsally

Figs. 6-12 drawn to scale below fig. 6; figs. 13-15, to scale below fig. 14,

below the pharynx, while the second and third travelled forwards, one lateral and

the other ventro-lateral to the pharynx.

The short posterior tubule almost immediately gave rise to several accessory

branches. The first passed upwards alongside the anterior collecting tubule, the

second between the ascending and descending main tubes; the third, fourth and

fifth were terminal, the third proceeding anteriorly to end behind the ventral

sucker, the median fourth lying between the other two and travelling backwardly

towards but below the excretory bladder, and the fifth dorsally towards but

above the bladder. The bladder and the proximal ends of the main excretory

tubes were lined with cuticle.

The correct number and arrangement of the flame cells and excretery tubules

could not be determined owing to the small number of cercariaea available for

study, their thickness, and the small size of the flame cells. The figure and

descriptions of this system, therefore, give only an approximation of their

arrangement.

RELATIONSHIPS

The cercariaeum stage of Leucochloridiwm australiense differs from that of

L. macrostomum (Rud.) and L. problematicum Magath in size, and also in the

absence of cilia on the general body surface. It is slightly smaller than

L. macrostomum which is 0-85 mm. long and 0°45 mm. broad, and much smaller

than L. problematicum which is 2°2 mm. by 0-85 mm. The anterior sucker,

pharynx and ventral sucker also differ considerably and in L. australiense are

almost circular, measuring, respectively, 193 », 69», and 154 in diameter. In

L.. problematicum they measure, respectively, 0-4 mm. long and 0-24 mm. wide;

0-17 mm. and 1°15 mm.; and the almost circular ventral sucker 0°34 mm,

Laurer’s canal in the Australian species opens into the excretory bladder as

in L. problematicum, and not on the dorsal surface as in L. mecrostomum; while

the intestine resembles that of the former species.

The reproductive system differs in the relationships of the ovary and the

two testes from L. assamense Sewell (1922), and is similar to that of L. macro-

stomum and LL, problematicum, except that in our specimens no true cirrus sac

is present as the uterus and vas deferens pass together through an undifferen-

tiated cell mass prior to opening at the gonopore. This condition may perhaps

become altered in later larval development.

Our species appears to come nearest to L. problematicum and L. tmsigne.

In the study of species of Leucochloridium more attention has been paid to the

natural history of the mother sporocysts than to the cercariaeum, with the result

that few of the latter have been adequately described. The first of these,

L. macrostomum (Rud.), was described by Heckert in 1888 under the name ot

L. paradoxum, and an account of its histology, morphology and life history

was given.

In 1920 Magath described a new species, L. problematicum, from North

America, which greatly resembled the marita of L. insigne described by Looss in

1899 from European birds. Magath suggested that L. problematicum was the

parthenita stage of L. insigne, although the host of the latter, Fulica atra, was

stated not to occur in the region from which his material was derived, In view

of later data on the host specificity of species of Leucochloridium, Magath’s

suggestion is probably incorrect.

Sewell, in 1922, described the third cercariaeum as L. assamense, which does

not seeni to us to be a typical member of the genus.

Sinitsin (1931, 796) gave a brief summary of investigation on the family

Hatmostomidae, and included a revised classification of the Harmostominae

(thus excluding the Leucochloridiinae) and descriptions of various species. He

pointed out that the parthenita stage of the latter is specific and the marita stage

indiscriminate in regard to host relationship. But such a statement does not apply

to the Leucochloridiinae.

McIntosh (1933) described six new species of Leucochloridinm (marita

stage) and included a key for the differentiation of all known species. This was

largely based upon the distribution of the vitellaria, size of fecundarium, etc.;

characters which could not be determined satisfactorily in the larva, and were,

thercfore, not of much assistance to us in placing our new form. An important

deduction from this paper, mentioned by Woodhead (1935), is that species of this

genus are specific in their bird hosts.

Wesenberg-Lund (1931) gave a full account of the biology of L. paradoxum

(i.e., macrostomum) and discussed ihe papers of Heckert, Magath and Monnig.

He believed that Magath had erected his new species L. problematicum on insufh-

cient data, and suggested that the brown sacs described by that investigator in

America belonged to the same species as those found by Heckert and Moénnig in

Europe. But it seems to us possible that sporocysts, apparently similar, may give

rise to different cercariaea. In one of his figures, Wesenberg-Lund (193], 95,

fig. 3) shows a cercariaeum from a brown sac and one from a green sac, and

mentioned a slight difference in regard to the sizes of the suckers. His figure

indicates the ratio of the anterior to the ventral sucker as 5:4 in the case of

the cercariaeum from brown sac, and 1:1 from that from a green sporocyst. In

his later figures (Wesenberg-l-und, 1934, pl. xxxii, figs. 7, 8) a slight difference

is to be observed in the sucker ratio of the two cercariaea assigned to L. para-

doxum. This ratio is 4:3 in the cercariaeum in fig. 8, and 10:9 in the ccrcariaeum

in fig. 7, but Wesenberg-Lund does not state from what kind of sac they were

obtained.

Liihe (1909, 209, fig. 188) has drawn a lateral view of the cercariaeum of

L. macrostomum. Woodhead (1935) gave a description of four new Leucoch-

loridium sacs, one of which is very like, and may prove to be identical with, that

already described by Magath. He remarked upon the specificity of Leucoch-

loridium maritae as regards their hosts, implied in McIntosh’s paper, but this

theory, according to Wesenberg-Lund (1931, 133, 134), is not substantiated on

account of the presence of the maritae of 1. macrostomum and L. insigne in a

number of different bird hosts. In 1936 he referred to an extraordinary case of

multiple infection of Succinea retusa with the sporocysts of Leucochloridium.

Gower (1936) gave a description of a new sporocyst of Leucochloridium

from Louisiana and included a camera-lucida drawing of the cercariaeum. This,

he stated, differed from L. problematicum in the sucker ratio, which was approxi-

mately 2:1 in his specimen, but he gave no account of the anatomy.

Yamaguti (1935, 173) described a new marita, L. sime, which resembled most

closely L. variae McIntosh (1932).

ADDENDUM

Since this paper was accepted for publication, Monnig’s (1922) important

paper on Leucochloridium macrostomum has become available. His account of

the female ducts does not agree with their disposition in our material, and we

would suggest that he has probably confused the ascending and descending limbs

of the uterus in the vicinity of ihe albumen gland. We were unable to find any

connection between the albumen gland and the enlarged part of the descending

uterus such as he indicates in his fig. 21.

The sense cells referred to in our paper as occurring in the vicinity of the

mouth and pharynx may perhaps be similar to structures indicated in his pl. v,

fig. 27, and which he has called “epithelial cells” and “pharyngeal pocket epithe-

lium” respectively. The distribution of colouration of the pulsating sacs differs

considerably for the Australian and European forms as figured by him.

NEW SPECIES FROM AUSTRALIA AND THE FIJI ISLAND

WITH SOME REVISIONAL NOTES

| Read 14 April 1938]

In my first paper on the Australian Fauna“ I neglected most of the

Cryphalinae and merely recorded others. Since then the South Australian

Museum has kindly placed more types at my disposition, which now affords me

the opportunity to publish more on some of these very difficult species.

Other material I have received from the Imperial Institute of Entomology

in London, the Dominion Museum at Wellington, New Zealand, and the Museum

Royal d’Histoire Naturelle de Belgique at Bruxelles. Some of the original

descriptions are so brief that determination necessitates a more detailed descrip-

tion, aside from some illustrations. Both shall be given below. From all the more

difficult specimens balsam mounts of the antennae have been prepared.

HYLESINUS CORDIPENNIS Lea

Aside from the type, | have not seen any specimens. Cordipennis is a true

Hylesinus, 3°3 mm. long, 1*7 times as long as wide, widest at the middle, oval

in outline, the apical margin of the pronotum and the elytra broadly and similarly

rounded. Elytral interstices with inconspicuous short and dark scales.

Leperisinus tricolor, n. sp.

A bright coloured species, 3:1 mm. long, 2:1 times as long as wide. Easily

separated from the other Australian species, . bunaculatus m., by its size and

vestiture.

Front opaque, convex, densely granulate punctate, with short, rather dense

and yellow pubescence, a shallow transverse impression just above the epistomal

margin.

Pronotum wider than long (40:32), base bisinuate, postero-lateral angles

rectangular, strongly rounded, sides feebly arcuate, subparallel on the basal

half, strongly constricted in front, antcrior margin moderately broadly

rounded, disc with a strongly developed transverse impression along the anterior

constriction, otherwise feebly convex, densely covered with short, smull and

dark reddish-brown scales, intermixed with scattered larger and pale yellowish

ones, these more numerous along the median line behind and on the postero-

lateral corners on each side of the median line with a dark semi-circular marking.

Elytra wider (49:40) and 2:1 times as long as the pronotum, each elytron

broadly arcuate at the base, sides parallel up to the middle, then gradually

narrowed, apex rather narrowly rounded, declivity commencing at the middle,

gradually and somewhat obliquely declivous; striate punctate, striae very narrow,

punctures indistinct, interstices feebly convex, densely covered with scales of

different colour, each interstice also with a somewhat irregular double row of

larger erect scales, ground colour a deep dark reddish-brown, with three wavy

transverse and brighter coloured bands, the first near the base indistinct, produced

by pale yellowish top scales only, the second more distinct, top and ground scales

of the same colour, the third broad, on the declivital convexity and laterad abruptly

ceasing, of a reddish-brown colour, another patch of similar colouration along

the suture and on the sides behind.

Hyleops, new genus

True Hylesinidae of the general shape as in some species of Leperisinus

Reitter, with 7-segmented antennal funicle (fig. 1), large elongate 3-segmented

antennal club, long oval eyes, finely and uniformly sculptured pronotum, striate-

punctate elytra and ascending abdominal sternites. Characters which do not

permit including it in any of the known genera are: the absence of scale-like

vestiture on the pronotum and elytra, and especially the development of the front

tibiae. The latter is widened distally, strongly compressed, with a series of small

equal-sized serrations on the outer margin. All allied genera show at least on

the front tibiae several large teeth on the apical edge. The groove for the

reception of the tarsus is short and subtransverse, the front coxae are moderately

remote,

Hyleops glabratus, n. sp.

Female—Dark reddish-brown, 3°4 mm. long, 2:2 times as long as wide.

Front convex, subshining below, opaque above, with a very shallow semi-

circular impression in the lower half, very densely and very finely punctured,

with fine and inconspicuous pubescence.

Pronotum wider than long (15:10), widest in the basal third, base as in

the allied genera strongly bisinuate, postero-lateral angles rectangular, feebly

rounded, sides parallel on the basal third, obliquely narrowed in front, the anterior

Redescription of the Genus

General shape long cylindrical, very similar to that in the genera Dendroc-

fonus Er., Hylurgus Latr. and Blastophagus Eichh.

Front convex, more or less transversely impressed, the rostrum short and stout,

antennal funicle 7-segmented, club pear-shaped, not at all compressed, 4-segmented.

Pronotum rather feebly convex, anteriorly with a well-developed constriction,

usually with a well-defined impunctate smooth median linc, sculpture uniform all

over, punctate.

Elytra cylindrical, declivity convex, rather coarsely sculptured, ninth inter-

space carinate and serrate in the posterior half, projecting over the lateral margin,

declivity usually with two types of vestiture, short, stout and densely placed

scales and long stiff bristles. Tibiae triangularly widened distally, with apical

teeth, abdominal sternites II-IV as long as V or II.

Pacuycores (HyLEsiNuS) PEREGRINUS Chap.

= Pachycotes ventralis Sharp

Chapuis’ type is dark reddish-brown, 4-0 mm. long, 2°3 times as long as wide.

Three specimens which I received from Dr. Clark, of the New Zealand State

Forest Service, and which apparently have been compared with Sharp’s type, are

somewhat larger, 4°8 mm. long, but otherwise agree in all respects with Chapuis’

species.

Front convex, with a subcircular shallow impression between the eyes, the

centre of it and the lower part of the median line polished and impunctate, remain-

ing surface densely granulate-punctate. Epistomal process as in Dendroctonus

simplex Lec.

Pronotum longer than wide (52:45), base strongly bisinuate, postero-

lateral angles rectangular, feebly rounded, sides subparallel, then strongly

narrowed, anterior constriction well developed, dise feebly convex, with a shallow

transverse impression along the anterior constriction and a second one along the

base, the latter more strongly developed on the sides; surface subshining, densely

covered with large but shallow punctures, median line impunctate. Scutellum

very small and shining.

Elytra hardly wider (58:52) and nearly twice as long as the pro-

notum, sides parallel, broadly rounded behind, declivity commencing behind the

middle, evenly convex; disc deeply striate-punctatc, strial punctures small and

elongate, interspaces wide and convex, covered with densely placed transverse

rugae; declivity with the strial punctures larger and more circular, the inter-

spaces narrower, less convex, very finely and irregularly punctured and covered

with very small scale-like hairs, each interstice also with a row of remotely placed

small setose granules, the latter more strongly developed at the commencement

of the declivital convexity.

The type is a male. The female has the front evenly convex, without the

circular depression but with the median line finely carinate on the lower half.

Pachycotes australis, n. sp.

Male—Piceous, 3:7 mm. long, 2:2 times as long as wide. Of the same

general shape as the genotype, but somewhat stouter and with different sculpture.

Front, convex above, flattened and feebly concave below, epistomal margin

developed into an oblique transverse strip, the upper lmit strongly elevated,

especially in the middle, median line narrowly carinate on its lower third, entire

surface subshining, sparingly and finely punctured, the centre of the impression

impunctate.

Pronolum wider than long (50:38), general shape as in P. peregrinus Chap.,

the punctures larger, intermixed with some smaller ones, shallow and disclosing

the bottom, near the apex and along the median line the punctures becoming

smaller, more remotely placed and with the outer margins asperity-like elevated.

Elylra as wide (52:50) and twice as long as the pronotum, opaque, in

outline and general shape as in P. peregrinus Chap., the declivity more strongly

convex; the strial punctures shining and circular throughout, smaller on the

declivity, interstices more coarsely and less densely wrinkled on the disc,

between the rugae with minute irregularly placed punctures, declivity with the

tubercles comparatively larger, the interspacial punctation very minute, the scales

very densely placed.

The female is larger, 3-8 mm. long, somewhat more slender, the front dull,

rather coarsely granulate-punctate, without median impression, but with an arcuate

impressed line shortly above the similarly constructed epistomal margin; pronotum

less strongly constricted in front, the sides more evenly rounded; the elytra with

the rugae of the interspaces much coarser and comparatively fewer in number.

Pachycotes clavatus, n. sp.

Male—Piceus, 3°6 mm. long, 2°2 times as long as wide. The peculiar frontal

characters, the inseration of the antennal funicle and the sculpture separate this

species easily from its allies.

Front deeply coneave on

the greatest part, concavity

extremely small, somewhat larger but hardly more distinct on the declivity,

interspaces subshining, less convex than in the two preceding species, the

uniseriate setose granules larger and on the first three interspaces extending over

the apical two-thirds, on the basal third with rather fine and moderately closely

placed transverse rugac, the irregularly placed small interspacial punctures

numerous, the scales not as densely arranged as in P, australis (abraded ?), the

declivital convexity slightly projecting over the apical margin.

Female with the front evenly convex, granulate-punctate, more strongly

Cryphalus subcompactus, Lea

dorsal aspect and elytral detail

HypocrypHaLus Hopk. and DacrypHatus Hopk.

The generic differences between Hypocryphalus and Dacryphalus seem to

me not very convincing, especially because Hopkins did not say much about the

retuse clytral declivity in the description of the species. Yo use the number of

sutures, more correctly the rows of bristles, indicating the number of sutures for

separating the genera, even in a group where antennal characters are of greatest

importance, will hardly prove of value. Therefore, the question still has to be

settled whether both genera stand or one of them has to be withdrawn, For the

present I unite the species having a 5-segmented antennal funicle, the club more

or less evenly rounded in outline, and with the sutures indicated by rows of

bristles on both sides of the latter under the name of Hypocryphalus Hopk.

When more is known about the variation of the elytral sculpture, etc., and

characters have been found to justify the separation in the sense of Hopkins, it

will be easy to refer corresponding species to the genus Dacryphalus Hopk. again.

THE RED-BROWN EARTHS OF SOUTH AUSTRALIA

BY C. S. PIPER

Summary

From an economic standpoint the red-brown earths constitute one of the most important soil groups

in South Australia, the most productive wheat-growing areas being on soils of this type. These soils

assumed considerable importance at an early period in the settlement of the State, both on account

of their geographical situation and the readiness with which they could be brought into pastoral or

agricultural production. However, following the initial period of development, there was a general

decrease in their fertility, and it was not until after the introduction of superphosphate towards the

close of last century, and the adoption of better farming methods, that increased yields were

obtained.

I INTRODUCTION

From an economic standpoint the red-brown earths constitute one of the

most important soil groups in South Australia, the most productive wheat-growing

areas being on soils of this type. These soils assumed considerable importance at

an early period in the settlement of the State, both on account of their geographical

situation and the readiness with which they could be brought into pastoral or

agricultural production. However, following the initial period of development,

there was a general decrease in their fertility, and it was not until after the

introduction of superphosphate towards the close of last century, and the adoption

of better farming methods, that increased yiclds were obtained.

The principal occurrence of these soils is along the western slopes of the

Mount Lofty Ranges and on the central highlands of the Middle North of South

Australia. They are developed as a longitudinal belt extending for about 150 miles

north of Adelaide. Most of this country lies between the 500 feet and 2,000 feet

contours. The physiography has been dealt with by Fenner (1930). In the

northern portions of the area the soils are typically developed in a series of wide

and roughly parallel valleys which run for considerable distances in a general

north and south direction. The soils of this group also extend along the coastal

portion of the Mount Lofty Ranges, south of Adelaide. Typical red-brown earths

are also found on the coastal plain, north of Port Lincoln, but so far no samples

from this locality have been examined in the laboratory.

Figure 1 shows the localities from which profiles have been examined, and

this gives an indication of the general distribution of the soils throughout the

central and middle northern districts of South Australia. For details showing

the limits of distribution of the red-brown earths Prescott’s Map of the Soils of

Australia (1931) may be consulted.

The soils under discussion are typically brownish loams to sandy loams in

the surface horizons, becoming redder and heavier with depth. Geologically, they

have been developed on Pre-Cambrian shales, slates and schists, or on alluvial

deposits derived from these rocks, Where the soils occur on alluvial deposits, as

on the plains and in valleys, they are very uniform over large areas and the profiles

are deeper than on the rises of undulating country. The geology of the area has

been dealt with by Howchin (1918), but his Lower Cambrian Series is now

recognised as Pre-Cambrian (Ward 1928). More recent geological information

will shortly be published by Segnit.

While red-brown carths normally occur on the shales and slates in this area,

grey to greyish-brown soils, related to the rendzinas, frequently develop in places

where the parent rock is more highly calcareous. Areas of these grey soils may

be surrounded by typical red-brown earths, and some examples of such occurrences

are included in Table ITI of the Appendix to this paper.

The mean annual rainfall throughout the area varies from 16 to 25 inches

per annum. The seasonal distribution shows a very marked winter maximum,

approximately 75 per cent. of the total falling during the months of April to

October. The average rainfall per wet day is greater than that in the Mallee

areas, varying from 0°19 to 0-24 inches, The Meyer ratio of precipitation to

saturation deficit ranges from 75 to 150. The climatic control of this soil group

has been dealt with by Prescott (1934).

The efficiency of leaching of the rainfall is stich that well-defined soil

horizons have been developed and calcium carbonate has generally been com-

pletely removed from the upper part of the profile. However, cyclic salts have

not been entirely removed from the region as a whole and there is a tendency for

some acctimulation to occur, in isolated cases, under favourable topographical

conditions.

Ecologically, the red-brown earths are clearly distinguished, on the one hand,

from the drier Mallee areas, and, on the other hand, from the sclerophyll forests

which occur on the more highly podsolized soils of the Mount Lofty Ranges.

The vegetation is typically open savannah woodland, peppermint gum (Eucalyptus

odorata) being the most prominent tree. ‘lowards the drier northern limits

this species frequently develops a mallee habit of growth. However, some of

the plains country (e.g., Booborowie Flats) was open grassland in its original

state and never carried timber. The surrounding hills carried blue eum

(Eucalyptus leucoxrylon) and she-oak (Casuarina stricta), Around Jamestown

the plains originally carried small acacia and peppermint gum with a mallee habit,

while the hills were covered with she-oak and tussock grass.

Blue gum (Eucalyptus leucoxylon) replaces peppermint gum as the charac-

teristic tree in the wetter portions of the area, while she-oak occurs extensively

in the drier regions as well as on the shallower and more stony soils clsewhere.

The vegetation has been recently described by Wood (1937).

The experimental farms of the Waite Institute and Booborowie have been

established on soils of this group, although experimental work at the latter place

was discontinued in 1930, For the response to various fertilizer and cuitural

treatments, the reports of these centres should be consulted. Statistics showing

the average wheat yields over a period of twenty years for each individual

hundred have been published by Perkins (1936), and Phipps has summarized

the mean yield and its variability for the Agricultural Development Com-

mission (1931).

During 1934 samples representing thirty typical profiles of the red-brown

earths were collected throughout the Lower and Middle North of South Aus-

tralia. ‘Three profiles representing greyish calcareous soils associated with this

group were also sampled. In addition to these, four other red-brown earth

profiles were available in the Waite Institute soils collection, Altogether thirty-

seven profiles, consisting of two hundred and eleven individual samples, have been

examined in the laboratory. The localities from which these profiles were

collected have already been indicated in figure 1. For permanent reference a

more detailed description and the complete analytical data for each profile are

recorded in the Appendix to this paper.

II THE WAITE INSTITUTE PROFILE

Since the soils at the Waite Institute are very typical of the red-brown

earths, two profiles have been sampled and examined in considerable detail (see

Appendix, Table 1). At this locality the soil has developed on an alluvial fan

from the foothills of the Mount Lofty Ranges and the parent material is derived

from the adjacent Pre-Cambrian shales and slates. In one profile (U69)

samples have been collected at each successive inch to a depth of 46 inches, so

that the variations in the profile can be very fully followed.

The surface soils have a characteristic brown colour, due to the presence of

organic matter in this horizon, but as its amount decreases in the profile the

colour of the mineral portion of the soil predominates, gradually changing to a

reddish-brown at 12-18 inches and to red in the deep clay.

Although calcium carbonate has not been removed [rom the lower horizons,

the soil is weakly podsolized and cluviation of the clay has occurred. This change

in the mechanical composition of the profile is very clearly seen in figure 2.

The surface soi! consists of a friable loam: with a very pronounced fine sand

fraction. The proportion of clay decreases somewhat during the first few inches

and then gradually increases to a well-defined illuvial zone of heavy clay. The

inch by inch profile (U 69) was not sampled below this zone, but the nature of

the lower horizons can be seen in the second profile (U 151) which represents

a slightly shallower phase, having its clay horizon nearer the surface. Below this

illuvial horizon the amount of clay again decreases, and at this point calcium

carbonate appears in the profile, having been completely leached from the over-

lying A and B, horizons.

There is a remarkable constancy between the relative proportions of fine sand,

coarse sand, and silt throughout the profile, and this is shown graphically in

figure 3. The nearly constant proportion of these three fractions, which together

constitute the non-colloidal framework of the soil, shows clearly the uniform

nature of the original parent material throughout the profile, and it also shows

that the changes in the colloidal fraction (clay) of the different horizons has

been brought about by a process of eluviation. This accumulation of clay in

the B, horizon has occurred as a result of its dispersion and mechanical eluviation

under the slightly acid conditions existing in the surface soil, An examination

of the silica: sesquioxide ratios for profile U 151 shows that there has been only

a small amount of leaching of the sesquioxides from the surface layers into the

lower horizons. The values for the free ferric oxide in the different parts of the

profile (Table I) also show that there has been little actual decomposition of the

clay to silica and sesquioxides, as occurs in podsols.

amounts of coarse sand and coarse sand -+ fine sand,

respectively, in the non-colloidal fraction of profiles

U 69-U 111 (left) and U 151-U 157 (right).

The amounts of organic carbon and nitrogen decrease progressively through-

out the profile, and the carbon: nitrogen ratio changes from about 13 in the

surface horizon to a value of 7-8 at a depth. The humus content of U 151 profile

has been determined by Mr. A. B. Beck and the values, given in Table I, show a

gradual decrease in amount with depth.

The amount of potash extracted by digestion with hydrochloric acid is closely

related to the amounts of silt and clay in the profile, and this relationship for

the U 69 profile is shown graphically in figure 4, From this diagram it is seen that

% K,O = 0.0155 * (Clay Percentage + $ Silt Percentage),

Although the soils are somewhat unsaturated with bases in the surface

horizons, the values ranging from 60 to 65 per cent. of full saturation, the per-

ceritage saturation increases progressively with depth and the horizons below

the appearance of calcium carbonate are fully base saturated. The corresponding

values for soil reaction range from pII 6-0 at the surface to pH 8-6 in the lower

horizons. Calcium is the dominant exchangeable base in the surface soil and

accounts for the good texture in the field. The proportion of magnesium, how-

out the profile, indicating that the leaching conditions and calcium status of the

soil are sufficiently good to remove cyclic salts, without an accumulation of

exchangeable sodium.

During the course of other investigations a number of the physical constants

have been determined for the Waite Institute soils, and for convenience these

values are recorded in Table I]. Although the various determinations have been

made on samples from different portions of the Waite Institute experimental

fields the soil is of sufficient uniformity for comparisons to prove of interest.

III LABORATORY EXAMINATION OF THE SAMPLES

(a) Mechanical Analysis

As already mentioned, the parent material on which the red-brown earths

are developed is such as to give rise, naturally, to soils of medium to heavy

texture. Since the surface soils are generally neutral to slightly acid in reaction,

some downward leaching of the clay has occurred, resulting in a surface soil of

lighter texture overlying a marked zone of clay accumulation in the B, horizon.

This downward leaching of the clay under neutral to slightly acid conditions is

very typical of the group as a whole, although a few profiles have been encountered

in which the accumulation of clay has probably resulted from its peptization and

greater mobility in the presence of important amounts of exchangeable sodium.

Such profiles, however, are not typical and only occur where topographic or

climatic conditions have produced an accumulation of soluble salts.

Figure 5 shows graphically, in the usual triangular diagram, the proportions

of sand, silt and clay in the red-brown earth profiles examined. It will be seen

that the surface soils are generally sandy loams, loams, or clay loams, while the

subsoils are much heavier in texture with a very large proportion falling into the

heavy clay group. Silt is almost always over 8 per cent. and is generally a

characteristic fraction amounting to 10-35 per cent. of the carbonate-free. mineral

fraction of the soil. In a few profiles, particularly one from the Booborowie

Flats (3810-3814), the silt fraction is dominant. In the soils examined, all of

the texture classes except sand, sandy clay loam, and sandy clay are represented.

The amounts of coarse sand, fine sand, and silt plus clay are represented

graphically in figure 6, and this triangular diagram shows very clearly the high

ratio of fine sand to coarse sand. In 60 per cent. of the samples examined this

ratio was greater than 3. The mincralogical composition of the parent material,

no doubt, accounts for the low amounts of coarse sand in these profiles.

(b) Calcium Carbonate.

The majority of the surface soils of this group are free from calcium

carbonate, or contain only very small amounts, owing to the leaching of the

carbonate into the lower horizons. The maximum concentration generally occurs

in the B, horizon, immediately below the zonc of clay accumulation. Below this

horizon the amount decreases somewhat.

Table HI gives the frequency distribution of the calcium carbonate per-

centages in the series of soils examined, and shows clearly the enrichment of

the subsoil.

The surface soils of the red-brown earths are slightly acid to slightly alkaline

in reaction while, owing to the frequent occurrence of calcium carbonate in the

lower horizons, the subsoils are nearly always neutral to alkaline. Most of the

surface soils with a reaction greater than pH 7 occur in the more northern areas

where, owing to the drier climatic conditions (lower rainfall and higher evapora-

tion), leaching has not been so complete.

The presence of small amounts of exchangeable sodium in the lower horizons

of some of the profiles has resulted in values for soil reaction in excess of pH 8-4.

In two or three profiles, in which the larger amounts of exchangeable sodium

were found, values up to pH 9-6 have been recorded.

All determinations have been made on a 1:2°5 water suspension, and the

glass electrode was used throughout. Table IV shows the frequency distribution

of these soils with respect to hydrogen ion concentration.

(d) Nitrogen and Organic Matter

The typical brown colour of the surface soils is due to the effect of organic

matter in modifying the red colour of the mineral fraction. The amount, how-

ever, is seldom great except in a few profiles. In the latter cases, as a result of

an increase in the water supply to the soil, brought about either by underground

sources or by the topographical features of undulating country diverting the

surface run-off to the lower lying flat areas, there has been an increased growth

of vegetation leading to these particular soils containing somewhat higher

quantities of organic matter than average.

The amounts of organic carbon and nitrogen present in the surface nine

inches have been computed for 33 profiles, for which figures are available and the

following are the mean values :—

Organic carbon - - 0°94%

Nitrogen - - - 0:097%

The organic matter decreases rapidly with depth throughout the profile,

resulting in a much redder colour in the subsoils. Tables V and VI show the

frequency distribution of the percentage of nitrogen and organic carbon, respec-

tively, in the soils and subsoils examined.

The carbon: nitrogen ratio varies within wide limits, as is seen in figure 7.

The ratio becomes narrower with depth, and a number of subsoils show values

less than 5:1. For the majority of the surface soils to a depth of 9 inches the

ratio lies between 12:1 and 8:1.

The continued cultivation of these soils for cereal production under the older

rotations, in which a period of bare fallow alternates with one of crop, must

inevitably lead to a serious decline in the organic matter reserves. No quantitative

data bearing on this question are available, but the consensus of opinion among

farmers who have cultivated these soils for long periods is that it is becoming

increasingly more difficult to secure a good tilth during cultivation. From this

it would appear that the reserves of organic matter are already being depleted.

black circles represent subsoils.

In order to maintain the fertility and to improve the mechanical condition of these

soils the organic matter content should be built up. A system of rotation which

includes a period under pasture is highly desirable.

(e) Potash and Phosphoric Acid

Only potash and phosphoric acid have been determined in the hydrochloric

acid extracts of these soils. All the soils examined are well supplied with potash,

amounts above 0°5% K,O being general in the surface soils. Larger amounts

are present in the subsoils. While the correlation between the clay and silt

content of the soil and the amount of potash does not hold so closely for this

group of soils as it does for the Waite Institute profile, the same general relationship

is noticeable and the percentage of potash ranges from 0-015 to 0:029 * (Clay

Percentage + % Silt Percentage), From the values for exchangeable potassium,

which are given in another section, it will be seen that the soils are well supplied

with this element in a readily available form.

Phosphoric acid generally ranges from 0:03 to 0°07 per cent. in the surface

soils, with somewhat smaller amounts in the subsoils. It will be noted that these

soils contain distinctly more phosphoric acid than do the mallee soils, the latter

seldom exceeding 0°03 to 0°04 per cent.

Table VII illustrates the frequency distribution of the potash and phosphoric

acid contents of these soils, while the individual values are tabulated in the

Appendix.

Two profiles (3778-3781 and 3782-3784), collected in the Hundred of Belalie,

show the relatively high phosphoric acid content of 0°16 to 0°18 per cent. P,O,.

Although these particular soils occur in association with the red-brown earths,

they do not belong to the group, having been developed on a highly calcareous

parent material. The soils are greyish-brown in colour and contain considerable

amounts of calcium carbonate in all horizons. In view of the higher phosphoric

acid content of these soils, it is interesting to note that Jack (1919) has reported

the occurrence of small phosphate deposits, in a formation of a similar descrip-

tion, seven miles to the north of this locality.

(f) Reactive Manganic Oxide

The amount of manganese brought into solution by leaching with a normal

solution of ammonium acetate, adjusted to pH 7 and containing 0-2 per cent. of

hydroquinone, has been determined for one complete profile (U 151) and for the

surface soils of the remainder, According to Leeper (1934) this gives a measure of

the reactive forms of manganese, which may be considered to be readily available

to plants. The high values obtained, typical surface soils ranging from 160 to

750 parts of manganese per million parts of soil, indicate that these soils are

very well supplied with manganese. The mean value for 32 soils was 345 p.p.m.

In the few cases in which the amounts of exchangeable manganese and manganic

oxide were determined separately it was found that by far the larger portion of

the manganese occurred in the oxidized form. Exchangeable manganese was

absent in the alkaline subsoils, the reactive manganese existing in these entirely

as oxide. Evidence of the occurrence of reactive manganic oxide in these soils

is also furnished by the rapid drift which occurs when attempts are made to

measure their reaction by the quinhydrone electrode.

In the Waite Institute profile (U 151) the reactive manganic oxide decreases

steadily from its maximum concentration of 430 p.f.m. in the surface horizon

to a minimum of 110 p.p.m. in the B, horizon. It then begins to increase again,

reaching 230 p.p.m. at the lowest depth sampled. Since manganese is most

mobile as the manganous ion, it would appear that its concentration in the surface

horizon is connected with the more oxidizing conditions in this layer bringing

about its precipitation as oxide.

(g) Soluble Salts

Accumulations of soluble salts are not frequent in the soils of this group,

although occasionally, where such factors as topography and drainage have led

to their concentration, some difficulties have been experienced. In the samples

examined chlorides only have been determined, and the results are expressed

as sodium chloride. At a few localities appreciable amounts of chlorides were

present in the lowest depth sampled, but only in three profles did the total sodium

chloride content of the top 36 inches of soil exceed 0°10 per cent.

In order that a comparison may be made with the results published for

South Australian and West Australian mallee soils, the amounts of sodium

chloride present in the top 24 inches of soil have been computed for 31 profiles

and the values are set out in the form of a frequency table (Table VIII). From

this table it will be seen that the majority of profiles contain less than 0-02 per

cent. of sodium chloride in the top two feet of soil, and the mean value of all the

profiles examined is 0-025 per cent,

(h) Exchangeable Bases

The exchangeable bases have been determined in twenty-three profiles and

the individual results are tabulated in the Appendix. The values for seven typical

profiles, including that from the Waite Institute, which has been examined in

considerable detail, are represented graphically in figure 8. It will be seen that

calcium is the most important of the exchangeable bases in the surface horizons,

but appreciable amounts of magnesium occur, as is so frequently the case in

Australian soils. The proportion of magnesium increases with depth, and in

many of the subsoils it even exceeds the calcium in amount. Significant amounts,

of exchangeable sodium are also present in certain of the subsoils, especially

where soluble salts in excess of the average occur. As already mentioned,

valuable amounts of exchangeable potassium occur in all of these soils and the

proportion is highest in the surface soils, probably as the result of the enrich-

ment by plant residues.

As a check on the values for total exchangeable bases, the amounts of

ammonium absorbed by the soils, after leaching wilh a normal solution of

ammonium chloride, were determined for a number of samples, and the values so

obtained agreed very well with the sum of the individual bases displaced. For

the thirty soils for which figures are available the mean amount of ammonium

absorbed was 16-05 milligram equivalents per 100 grm. of soil, and the correspond-

ing values for the total exchangeable bases was 16°85 milligram equivalents.

The mean values for the percentage composition of the exchangeable bases

in the surface, subsurface and subsoils of twenty-two red-brown earth profiles

are presented in ‘lable IX. For comparison the corresponding values are given

for nine South Australian mallee profiles.

Illustrating graphically the exchangeable bases in seven representative red-brown

earth profiles. The amounts of clay are also indicated by means of the open circles..

It will be noticed that the red-brown earths are significantly lower than the

mallee soils in exchangeable sodium, especially in the deeper horizons of the

profile. With the exception of the Parafield profile (3694-3699) which, on

account of impeded drainage, cannot be regarded as normal, the exchangeable

sodium in the subsoils of the red-brown earths never attains the average value

for the mallee subsoils. Calcium and magnesium occur in about the same propor-

tion in the surface soils of both the above groups. However, while the propor-

tion of magnesium increases at approximately the same rate throughout the

profiles of both groups, the proportion of calcium does not decrease so rapidly

in the red-brown carths as it does in the mallee soils.

Exchangeable hydrogen has also been determined in these soils in order to

obtain a measure of their base exchange capacity and percentage base saturation.

The mean values for the twenty-two profiles are included in Table IX. These

figures show the slightly podsolized nature of the surface horizons, while the

subsoils tend towards full base saturation. The general relationship between

soil reaction and percentage base saturation is shown in figure 9,

By means of graphical methods, the contribution of the clay and organic

matter to the total base exchange capacity of the soil has been determined for

each profile. The values so obtained show that the base exchange capacity varies

in the different profiles from 0°39 to 0-61 milligram equivalents per grm. of clay,

while the soil organic matter has a base exchange capacity ranging from 2:2 to

61 milligram equivalents per grm. of carbon (Table X). Figure 10 shows

graphically this relationship between base exchange capacity and the amounts of

clay and organic matter. In the left-hand portion of the diagram the actual base

exchange capacity of the soil has been plotted against the calculated base exchange

capacity due to clay and organic carbon, using the values deduced for each profile

as given in Table X. In the right-hand portion of the figure the same relationship

has been plotted by using the mean values for the base exchange capacity of the

clay and organic matter, namely, 0°48 milligram equivalents per grm. of clay

and 3:8 milligram equivalents per grm. of organic carbon.

An examination of the values for the base exchange capacity of the clay

fraction of the red-brown carths shows only a general correlation with the silica:

alumina or the silica: sesquioxide ratio of the clay. The more siliceous clays

tend to have the greater base exchange capacity. This latter is apparently

influenced by other factors in addition to the above, and in this respect it is con-

sidered that the “International Clay” fraction includes too wide a group of

particles. Since base exchange is a surface phenomenon, the smaller particles

in the fraction would tend to contribute more to the total effect than would the

larger particles. A better correlation would probably be obtained with a fraction

of a smaller diameter than “International Clay.”

appropriate values given in Table X for each separate profile. In the right-hand

portion the average values for clay and organic matter, namely, 0-48 m.e. per grm.

of clay and 3-8 me. per grm. of organic carbon, have been used for all the soils.

(i) Composition of the Clay Fraction

A clay fraction with a maximum settling velocity of 0-O001 cm. per second

(corresponding to the former “British Clay”) was separated from each sample

of fifteen typical profiles and silica, alumina and ferric oxide were determined.

Table XI shows the frequency distribution of the silica: alumina and silica:

sesquioxide ratios in the soils examined, In general these ratios decrease from

the surface horizons to the B, horizon of clay accumulation, at which part of the

profile a small enrichment of sequioxides has occurred and the minimum ratios

are reached. In every case the ratios again become wider as soon as the calcium

carbonate horizon is reached.

IV THE POSITION OF THE RED-BROWN EARTHS IN THE

WORLD CLASSIFICATION

At the present time it is not possible to define clearly the position of the red-

brown earths in the World-Group classification of soils. They appear to have

certain affinities with the Mcditerranean red earths (terra rossa) and the brown

earths of northern Europe, but it is probable that they will be found to correspond

more closely with the former than the latter when further comparisons can be

made. This resemblance to the Mediterranean type would be expected from a

consideration of the climatic conditions, the South Australian red-brown earths

being developed in a zone of winter rainfall and summer drought. The occurrence

of rendzinas on the more calcareous parent materials throughout this zone also

suggests a further similarity with the soils of southern Europe, where the terra

rossa is associated with the development of rendzinas on the soft limestones. Like

the Mediterranean red earths, the South Australian red-brown earths are typically

slightly unsaturated in the surface layers and contain calcium carbonate in the

lower horizons. Unfortunately, owing to the paucity of good published descrip-

tions of representative red earth profiles, a more detailed comparison cannot be

made at present.

The red-brown earths are formed under open savannah woodland, the climatic

conditions being favourable to moderate leaching. The humus, although low in

amount, is well distributed throughout the top soil and shows no tendency to

accumulate either as a peaty surface layer or in the B horizon, as in podsols.

The soils are formed under conditions of free drainage.

The red-brown earths differ from the brown earths in that they show a

marked accumulation of clay in the B, horizon, while calcium carbonate occurs

in the B, and lower horizons. In this accumulation of clay the red-brown earths

show evidence of slight podsolization which may be the result of a smaller return

of bases to the surface soil than occurs under deciduous forest—the typical vegeta-

tion of the brown earth zone of northern Europe. Although mechanical eluvia-

tion of the clay has occurred under the slightly acid conditions prevailing in the

surface soil, the free sesquioxides, which are present in small amounts, have not

been leached out of the surface horizon to any great extent. In spite of the

evidence of incipient podsolization in the surface horizons, the red-brown earths

are more basic than the brown earths in the lower horizons owing to the presence

of calcium carbonate.

The silica: alumina and silica: sesquioxide ratios of the clay fractions of the

red-brown earths differ significantly from those of the podsols, corresponding

more closely with those of the brown earths and the terra rossa soils. A marked

decrease in the ratios on passing from the A to the B horizon, which is so charac-

teristic of podsols, is not observed in the red-brown earth profiles examined.

Although the ratio decreases slightly on passing from the A to the B, horizon,

it gradually widens again to equal or surpass that of the surface soil. According

to Robinson (1936) typical brown earth profiles are characterised by a fairly

constant silica: sesquioxide ratio down the profile, with a value generally

approximating to 2. This value is somewhat lower than that commonly found

for the present soils. Figures for the silica: sesquioxide ratio of the clay through-

out terra rossa profiles are not available, but the average value of 2°43 reported

by Reifenberg (1933) for surface soils agrees well with that found for red-

brown earths in the present investigation.

The red-brown earths differ in many respects from the South Australian

mallee soils. Texturally the former are heavier and contain important propor-

tions of silt. Mallee soils are more alkaline than the red-brown earths, calcium

carbonate generally being present in the surface of all but the sandier types of

the mallee group. The organic carbon, nitrogen, and phosphoric acid status is

also lower in the mallee soils, while the soluble salt content of the latter is greater.

The important differences in the exchangeable bases of these two soil types have

already been discussed. Another significant difference seems to be in the reactive

manganic oxide content of the surface soils of the two groups. The amounts

present in the red-brown earths are very much higher than in the heavier type of

mallee soils, while the mallee sands are much lower again,

V AGRICULTURAL PROBLEMS ASSOCIATED WITH

THE RED-BROWN EARTHS

Although these soils as a group are among the most fertile of the South

Australian wheat-growing soils, certain difficulties have arisen in limited areas.

Perhaps the most important is the phenomenon of “setting” after rain, exhibited

by a few soils of this type. When this is severe the top layer of the surface soil

runs together and sets to a hard compact crust when it dries out. This crust is

about half an inch thick and, under unfavourable weather conditions the

germinating wheat plants are often unable to force their way through it. This

leads to an uneven germination of the crop. The badly affected areas are irregular

in shape and occur scattered throughout the more normal soils. They are always

noticeably redder in colour than the normal soils because of their lower content

of organic matter.

In one example investigated near Riverton (Soil Nos. 3701-3708) the surface

soil of the setting type appeared to correspond to a B horizon. Its clay content

was somewhat greater than the normal phase, but the exchangeable sodium was

particularly high for a surface soil and constituted 26 per cent. of the total bases.

The corresponding value for the exchangeable sodium in the adjoining normal soil

was only 2 per cent. The “setting” soil was also much lower in organic matter.

The occurrence of the B horizon at the surface suggests that these soils may have

resulted from the loss of the surface layers by sheet erosion.

The most successful treatment of this condition would probably lie in the

building up of the organic matter content of the soil by a suitable system of crop

rotation and green manuring. Applications of gypsum should also assist in

reducing the proportion of exchangeable sodium and so improving the physical

properties of the soil. However, the effect of the increased organic matter would

probably be the more important since, in addition to its direct effect on the soil

tilth, it would also increase the biological activity in the soil. The carbon dioxide

produced as a result of this increased biological activity would assist in the replace-

ment of exchangeable sodium by calcium. The areas of “setting soils” are slowly

extending, due to the depletion of the soil organic matter as a result of the crop

rotations practised.

A second problem, also of limited importance, is the local development of

salt patches, where the topography is such that the soluble salts tend to accumulate

at the surface. A few such patches were seen, near Riverton, irregularly distributed

over some gently sloping country. Under a bare fallow crop rotation the area

of these patches gradually increases. “This extension can be checked, and the salt

concentration of the surface soil reduced, by maintaining a grass cover on the

land, so decreasing the actual evaporation from the surface soil, If kept under

pasture for a period of years, the salt gradually leaches to the lower soil horizons,

under the influence of the winter rainfall. However, even when the salt con-

centration is decreased, the composition of the exchangeable bases is altered and

the proportion of sodium increases. This change in the composition of the bases

adversely affects the soil texture. Here again the use of gypsum and a system

of rotation that increases the organic matter in the soil should be beneficial.

VI NOTES ON THE ANALYTICAL METHODS USED

The analytical methods used were those published elsewhere (Prescott and

Piper, 1928, and Piper and Poole, 1929), although many recent and unpublished

improvements have been adopted. The fractions separated in the mechanical

analysis were those adopted internationally.

The clay fraction separated for silicate analysis corresponded to the former

British clay fraction and had a settling velocity of 10-* cm. per second. Silica was

determined in this separate by the standard methods of rock analysis involving

fusion, double evaporation, ignition and purification by hydrofluoric acid.

Titanium was determined colorimetrically in an aliquot of the filtrate, iron and

titanium in another aliquot by precipitation with cupferron, while aluminium,

iron, and titanium were determined in a third portion by precipitation with

ammonia.

Organic carbon was determined gravimetrically by dry combustion. When

carbonates were present in the soil they were removed in a preliminary treatment

with sulphurous acid. Chlorides were determined by electrometric titration

(Best, 1929). The glass electrode was used for all pH measurements.

The exchangeable bases were obtained by leaching the soils with ammonium

chloride. Calcium was precipitated as oxalate, magnesium as phosphate or

8-hydroxyquinolate, potassium as perchlorate and sodium as a complex uranyl

magnesium acetate. When calcittm carbonate was present, it was necessary to.

determine exchangeable calcium and magnesium in sodium chloride extracts by a

slight modification of the method of Hissink (1923). The method of de’Sigmond

and Iyengar (1935) was tried, but was found to give erroneous results. Exchange-

able hydrogen was determined by the m-nitropheno! method (Piper, 1936), and

reactive manganic oxide by extraction with ammonium acetate and quinol at

pH 7 (Leeper, 1934).

U69-Utli* These samples represent a typical profile from No. 1 Experi-

mental Ficid at the Waite Institute, the profile being sampled in

inch layers to a depth of 46 inches. The surface soil consists of

brown loam or fine sandy loam and overlies a reddish brown clay

loam to clay with heavy red clay at a greater depth. Calcium

carbonate occured below the depth sampled.

GRAMINEAE

Stipa elatior, Hughes. Near Clare, E. C. Black.

LILIACEAE

Xcnthorrhoea quadrangulata, F. v. M. Grown from seed in Dr. E. C. Black’s

garden at Magill and fruiting in second year (December, 1937). Capsule brown,

glossy, l-seeded, rarely 2- or 3-seeded, about 15 mm. long, on a conical ribbed

rigid stipes about 5 mm. long, each of the three valves ending in a pungent mucro;

seed compressed, triquetrous, dull-black, about 10 mm. long. At this early stage

the plant has no stem, the older leaves lying flat on the ground.

PROTEACEAE

Hakea chordophylla, F. v. M. Fraser River 4 miles E. of MacDonald

Downs, C.A., 1930, J. B. Cleland. Wrongly recorded as “G. chordophylla,” p. 242

of last year’s Transactions.

Grevillea stenobotrya, F. v. M. Between Alice Springs and the Granites,

C.A., Sept. 1936, £. C. Black. The fruit is at first smooth and dark-reddish-

brown; after a time this dark epicarp breaks away in pieces and discloses a pale-

brown pitted endocarp. G. livea, Ewart et Archer, Fl. N. Terr. 84, t. 8 (1917),

is apparently a synonym of G. stenobotrya, F. v. M. (1875).

CRUCIFERAE

Blennodia blennodioides (F. v. M.) Druce in Rept. Bot. Exch. Club, 1916,

609 (1917). Hermannsburg, C.A., Aug. 1929, J. B. Cleland. First record for

Central Australia—Erysimum blennodioides, F. v. M. in Linnaea 25: 367 (1852) ;

Blennodia lasiocarpa, F. vy. M. in Trans. Phil. Soc. Vict, 1: 100, in adnot. (1855).

This last name was adopted by Bentham in the FL. Aust., but is not correct under

the International Rules of 1905 and 1930, which only forbid the use of specific

names “when they exactly repeat the generic name.”

Blennodia brevipes, F. v. M. in Trans. Phil. Soc. Vict. 1: 100 (1855) in

adnot. This small annual, found in all the southern States except Tasmania,

possesses the following synonyms :—Erysimum brevipes, F. v. M. in Linnaea

been found in South Australia.

LEGUMINOSAE

Cassia oligophylla, F. v. M. Vhe Granites, C.A., Aug. 1936, J. B. Cleland.

First record for Central Australia. Previously collected in north-west of

Western Australia and in western Queensland,

Leaflets silvery with a close appressed pubescence; pods 3-5 em. long, by

12-16 mm. broad. The flowers are in 6-flowered umbels, not in “short racemes.”

C. desolata also has the flowers usually in umbels.

Acacia Kempeana, F. v. M. Neepabuuna, Flinders Range, 1937, J. B.

Cleland. A new locality.

Psoralea pustulata, F. v. M, The Granites, C.A,, Aug. 1936, J. B. Cleland.

First record for Central Australia. The specimen agrecs with Bentham’s descrip-

tion, except that the terminal leaflet is lanceolate-oblong and 4-7 cm. long.

Jacksonia anomala, Ewart et Morrison. Between the Granites and Thom-

son’s Waterhole, C.A., Aug. 1936, J. B. Cleland. The two keel-petals are not

merely separate but are distant from each other and placed immediately against

the inner face of the two narrow wings (pl. iv, fig. 1).

Indigofera Georgei, E. Pritzel in Engl. Bot. Jahrb. 35: 268 (1904) = I. bovi-

perda, Morrison in Journ. Bot. 50: 166 (1912).

Centr. Aust —The Granites; Archibald’s Soak, near Coniston Station; W. of

Brook’s Soak, June 1936, J. B. Cleland.

This grey-tomentose plant, recognisable by its constantly five obovate leaflets

and its small red flowers, was also found on the Lander Creek by G. F. Hill in

1911 and recorded (as /. boviperda) by Ewart and Davies in Fl. N. Terr., p. 142.

Morrison distinguishes his I, boviperda from I. Georgei by stating that “the

leaves and pods are shorter and the racemes attain a greater length.” Neither of

these distinctions appears valid. Both descriptions agree as to the number, shape

and size of the leaflets, Pritzel says the racemes are 2-5 cm, long, his specimens

being in flower, with unripe pods (“legumen submaturum”) 3 em. long. In

Morrison’s specimens the petals had fallen, the pods were ripe and 12-28 mm.

long, and the racemes were 2-19 cm. long. Both these types came from the central

and northern parts of Western Australia. In our specimens from Central Aus-

tralia the leaflets are usually 6-12 mm. long, the long terminal ones rarely reach-

ing 25 mm.; the racemes are short and dense at first, but in fruit become loose

and lengthen to 15 cm. or more. The ripe pods are 2-4 em. long, with a rigid

mucro. The caducous bracts are broad-lanceolate and shorter than the flowers

they subtend.

Indigofera linifolia, Retz. The Granites, C.A,, Aug. 1936, J. B. Cleland.

Already recorded from the MacDonnell Ranges.

103

Indigofera lursuta, L. Pine Hill (north of MacDonnell Ranges and near

Hanson River), C.A., Aug. 1936, J. B. Cleland. The hairs of the stem and of

the leaf-rhachis are less spreading than in North Australian and Asiatic specimens.

Standard pubescent on back and keel pubescent on midrib; bracts about 5 mm.

long, oblanceolate, channelled above.

Indigofera viscosa, Lamk. Coniston Station; the Granites, C.A., Aug. 1936,

fruiting, J. B. Cleland, Recorded by Tate for Hermannsburg,

Crotalaria crispata (F. v. M.) Benth. The Granites, C.A., Aug. 1936, J. B.

Cleland. First record for Central Australia.

Tephrosia phaeosperma, F. v. M., ex Bentham, 20 miles south of the Granites,

C.A., Aug. 1937, J. B. Cleland, First record for Central Australia.

Tephrosia eriocarpa, Benth. The Granites, C.A., Aug. 1936, J. B. Cleland.

First record for Central Australia. In our specimens the flowers are mostly in

racemes, which in fruit become 15 to 20 cm. long.

Ptychosema stipulare nov. sp. Plantula procumbens, omnino (corolla

ovarioque exceptis) patenti-pilosa; caules plures, graciles, 10-20 cm. longi,

dichotome ramosi; folia distantia, 3-foliolata; foliola brevissime petiolulata,

obovata, 4-6 mm. longa; petioli filiiormes, 5-10 mm. longi; stipulae conspicuae,

orbiculari-acutae, circa 4 mm. longae; pedunculi, axillares, 1-flori, 15-20 mm.

longi, prope apicem articulati ct bracteati; bractea linearis, pedicellum brevem

superans; calyx 5 mm. longus, lobis lanceolatis, tubum subaequantibus, duobus

superioribus brevioribus; bracteolae 2, tubum calycis aequantes; vexillum ungui-

culatum, circa 7 mm. longum, cum alis brevioribus purpureo-punctatum; carina

flava, vexilla paulo brevior; stamina in tubum fissum connata; ovarium planum,

glabrum, 6-7-ovulatum, stylo brevi; legumen immaturum pl!anum, glabrum lineari-

oblongum, circa 25 cm. longum, 6-7 mm. latum, conspicue stipitatum (tab. iii, fig. 4).

Near Bundoona railway station, C.A., Aug. 1936, J. B. Cleland,

Resembles P. trifoliolatum, F. v. M., in habit, but differs in its covering of

spreading hairs, instead of being almost or quite glabrous; also in the leaflets,

which are not obcordate, and especially in the conspicuous stipules, which are

orbicular instead of small and linear. The upper lip of the calyx is not almost

truncate-emarginate, as in P. trifoliolatum, but consists of the two upper lobes,

which are lanceolate, like the three lower ones, although united for a short

distance. The colour of the flowers is also different, the standard and wings being

purple-dotted, while in P. trifoliolatum they are yellow, and in the latter species

the keel is longer than the standard.

Piychosema trifoliolatum, F. vy. M. Coniston, C.A., Aug. 1936, J. B. Cleland.

Recorded by Tate from near the James Range, C.A.

Desmodium parvifolium, DC. (pl. iii, fig. 1). The drawing is from a

specimen collected by Leichhardt at Archer’s Station, Queensland, and lent by

the Victorian National Herbarium. Not yet found in Central Australia. The

single leaflets are quite as numerous as the ternate ones; the hairs of the pod are

not hooked.

104

Desmodium Muelleri, Benth. (pl. iii, fig. 2). The drawing is from a fruiting

specimen collected by Dr. Maurice Holtze, probably near Darwin, in 1890, and

kindly lent by the Government Botanist of Victoria, Mr. I’. J. Rae. Another

specimen, from the Upper Victoria River, F. Mueller, also obtained on loan, has

unripe pods and longer leaflets, 14-3 cm. long. The leaflets in both specimens

are conspicuously reticulate and the hairs of the pods are hooked. Not yet found

in Central Australia. The late Prof. Ewart records (Fl. N. Terr. 150) specimens

collected on the Adelaide River, N.A., with pods indented on both sutures, and

which he refers to D. Muelleri, They may be D. neurocarpum.

Desmodium neurocarpum, Benth. (pls. iii fig. 3, and iv fig. 2). Archibald’s

Soak (between Coniston and the Granites), C_.A., Aug. 1936, J. B. Cleland. First

record for Central Australia. In the specimens from Archibald’s Soak the plant

is small and apparently procumbent, the leaflets are more often solitary than three,

mostly broad-oblong, 10-18 mm. long, 5-10 mm. broad. In the type-specimen

(pl. iv, fig. 2), collected by Mueller on the Upper Victoria River and kindly lent

by the Victorian National Herbarium, the leaflets are 15-35 mm. long and

5-8 mm. broad. In all specimens the terminal leaflct is the longest and the reticu-

lation is prominent, especially on the undersurface. The fruiting peduncles are

very slender and attain a length of 10-25 cm. Very near D. Muelleri, Benth.,

differing chiefly in the pod, which has the upper margin indented between the

articles, which are rather more strongly reticulate, and the hairs along the margin

are straight, while in D. Muelleri the upper margin is straight or almost so and

the hairs are hooked at summit.

It is probable that our Central Australian specimens are the same as

D. neurocarpum, Benth. var. queenslandicum, Domin in Bibl. Bot. 89: 768, which

is described as having shorter and broader leaflets than the type and very slender

prostrate branches. The variety is recorded by Domin from the Queensland

coasts and from near Hughenden, on the Flinders River.

MALVACEAE

Hibiscus

The position of Hibiscus brachychlaenus and its immediate allies was in-

correctly defined in the FI. S. Aust. 381 (1926) and an attempt is here made to

place them more satisfactorily.

SOLANACEAE

Solanum phlomoides (A. Cunn.) Benth, The Granites, C.A., Aug. 1936,

J.B. Cleland. First record for Central Australia. Ouly differs from Bentham’s

description in the leaves (5-9 cm. long by 24-34 cm. broad) being all obtuse and

none acuminate. The very large globular or ovoid fruit (3-4 cm. long) is exceeded

by the narrow-pointed calyx-lobes, which are about 4 cm. long, the whole calyx,

including the broad tube, being about 5 cm. long or rather more. The sceds are

very numercus and black. The fruit is (in our specimens) only produced by

the lowest flower of each raceme, the upper flowers being apparently male only

and caducous. The berry is eaten by the natives.

Solanum nemophilum, F.v. M. The type, from Queensland, had no prickles,

and the plant was so described; owing to this error it was re-described by me as

all our specimens show prickles, sometimes rather numerous, on the branches.

This species was collected by H. UH. Finlayson in January 1934, 60 miles south

of Ernabella, in the Musgrave Ranges—the only record for South Australia—and

the specimen was compared with the type in the Victorian National Herbarium.

MARSUPIALS

BY HARVEY T. JOHNSTON AND PATRICIA M. MAWSON

Summary

The collection of Filarial parasites from Australian marsupials at present under consideration was

obtained chiefly in Queensland, New South Wales and Central Australia. References to recorded

occurrences of these and other entozoan from this order of mammals in the Australian region were

brought together by one of us (Johnston, 1909, 191 1, 1916), but many were listed merely as Filaria

sp. Oldham (1933) gave a list of the entozoa reported from Australian and American marsupials.

AN ACCOUNT OF SOME FILARIAL PARASITES OF

AUSTRALIAN MARSUPIALS

By T. Harvey Jounston and Patricia M. Mawson

Zoology Department, University of Adelaide

[Read 12 May 1938]

The collection of Filarial parasites from Australian marsupials at present

under consideration was obtained chiefly in Queensland, New South Wales and

Central Australia. References to recorded occurrences of these and other entozoa

from this order of mammals in the Australian region were brought together by

one of us (Johnston, 1909, 1911, 1916), but many were listed merely as f*ilaria sp.

Oldham (1933) gave a list of the entozoa reported from Australian and American

marsupials.

In the present paper four species of Dipetalonema are described as new

(D, dasyuri, D. rarum, D. annulipapillatum and D. tenue), and an account is given

of D. roemeri (Linstow), D. spelaea (Leidy), and D. trichosuri (Breinl). Brief

relerence is also made to female specimens, listed as Dipetalonema sp., and

Filaria (s.l.) spp., from four different host species. Of the filariae already

described from Australian or New Guinea marsupials, three species have not

been identified amongst our material—Breinlia dendrolagt Solomon, 1933,

described from Dendrolagus inustus (New Guinea); Filaria dentifera Linstow,

1898, from Trichosurus vulpecula (Queensland) ; and Dipetalonema capilliforme

Baylis, 1934, from Dasyurus hallucatus (North Queensland).

The various parasites studied in the present paper are listed under their

respective hosts as follows :—

Macropus major Shaw—Dipetalonema roemeri (Burnett River, Queensland).

Macropus robustus Gould—D. roemeri (Cockatoo Creek and Mount Liebig,

Central Australia) ; D, tenue n, sp. (Cockatoo Creek and Mount Liebig,

Central Australia).

Macropus parryi Bennett—D. roemeri (Burnett River).

Macropus melanops Gould——D, roemeri (North Western Australia).

Macropus dorsalis Gray—D. annulipapilatum n. sp. (Burnett River).

Macropus ualabatus Less. and Garn—D. roemeri (Lower Hawkesbury, New

South Wales).

Macropus welsbyi Longman—D. roemeri (Stradbroke Island, South Queens-

land).

Dendrolagus lumholsti Collett — Dipetalonema sp. (? roemeri) (North

Queensland, from Melbourne Zoological Gardens).

Dendrolagus bennettianus De Vis—D. spelaea (North Queensland, from

Sydney Zoological Gardens).

Petrogale penicillata Gray—D. spelaea (Burnett River).

Trans. Roy. Soc. S.A., 62, (1), 22 July 1938

108

Onychogale frenata Gould—Dipetalonema annulipapillatum n. sp. (Burnett

River); D. rarum n. sp. (Victoria) ; D. roemer: (Burnett River).

Trichosurus vulpecula Kerr—D. trichosurt (Burnett River).

Trichosurus caninus Ogilby—Fuilaria (s1.) sp. (Townsville, Gosford, Lower

Hawkesbury River, New South Wales).

Potorous tridactylus Kerr—Filaria (s.1.) sp. (Dorrigo, New South Wales).

Dasyurus maculatus Kerr—Fuilaria (s.1.) sp. (Brisbane).

Dasyurus viverrinus Shaw—Duipetalonema dasyuri n. sp. (Victoria).

The last-named two hosts belong to the Polyprotodontia, all the others to the

Diprotodontia.

The host name Macropus major has been used instead of M. giganteus, of

which the former has long been regarded as a synonym. The confusion regarding

the correct name of the Great Kangaroo has been discussed by Iredale and

Troughton, who have pointed out that M@. major Shaw is the correct name for it.

M. giganteus of Erxleben and of Zimmermann belongs to the species seen by

Captain Cook in the vicinity of what is now Cooktown, North Queensland, this

species being a much smaller form, in fact, a wallaby, Wallabia cangaru Muller,

1776, whose range cxtends northwards to Cape York Peninsula (Iredale and

‘Troughton, Mem. Austr. Museum, 6, 1934, 55; Rec. Austr. Museum, 20, (1),

1937, 67-71). In our paper we have not utilized the subdivisions of the old genus

Macropus. We take the opportunity to correct an crror im Linstow’s paper (1898)

dealing with some parasites collected in the Burnett River region by Semon: the

name Dasypus hallucatus should be Dasyurus hallucalus, sloths (Dasypus) being

absent from Australia. The parasite referred to by Linstow was a larval ncma-

tode, recorded, perhaps incorrectly, as Ascaris sp.

We des:re to acknowledge assistance in regard to material from the late

Dr. T. L. Bancroft and from his daughter, Dr. J. M. Mackerras, for specimens

trom the Eidsvold district, Upper Burnett River, Qucensland; Mr. A. S. LeSouef,

Director, Taronga Zoological Park, Sydney, for worms from Dendrolagus and

Potorous; Professor O. W. Tiegs, University of Melbourne, for specimens from

Dasyurus viverrinus; and our colleaguc, Professor J. BR. Cleland, for parasites

from Macropus melanops, The remaining material was collected by the senior

author, much of it during the various anthropological expeditions to Central

Australia (1929-1937).

Types of new species have been deposited in the South Australian Museum,

Adelaide.

Wehr (1935, 87) erected the family Dipetalonematidae (Syn. Dirofilariidae

Sandground) to receive two subfamilies, Dipetalonematinae (to include Oncho-

cercinae Leiper as well as Loainae and Setariinae Yorke and Maplestone (in

part), and Dirofilariinae (a new subfamily for Dirofilaria and Loa). Chitwood

and Chitwood (1937) have accepted, in part, Wehr’s classification. We regard

Dipetaloncmatidac as a synonym of Sandground’s family, which has priority.

We follow Baylis (1934) in using Dipetalonema instead of Acanthocheilonema.

109

Dipetalonema dasyuri n. sp.

Figs. 1-7

The specimens occurred in large numbers in the body cavity of a “native

cat,” Dasyurus viverrinus, from Victoria. They are long, slender and much coiled.

The head is the shape of a truncated cone. There is a tapering tail on which are

a pair of sub-terminal papillae. A little back from the anterior extremity are two

pairs of large papillae, 0-008 mm. long in the male.

The male attains a length of 20 to 40 mm., and a maximum breadth of

0:17--26 mm. The head at its widest part is 0°1--13 mm. wide, and the breadth

taken just in front of the cloaca 0-092-:1 mm. The cuticle at about the middle

of the body is 2-7 thick. The nerve ring is 0°16-:22 mm. from the anterior

end. The tail region is coiled in a close spiral of three or four turns. The cloaca

is 0-4--5 mm. from the posterior end, so that the tail is one seventy-fifth of the

body length, Around the cloaca are four pairs of papillae, two pre-anal and two

post-anal. The spicules are unequal, one being 0-12 mm. and the other 0-2 mm.

long. They are of approximately the same shape, cylindrical at the upper or

proximal end, spatulate and curved at the distal end, to terminate in a point which

is more drawn out in the longer spicule. The testis tubule begins in a swollen

portion just posterior to the ocsophagus, and is straight for some distance, then

coiled. The wide oesophagus consists of an anterior narrower portion, 0°29 to

*32 mm. in length, and a longer wider region 1:1 to 1:2 mm. in length, 7.¢., about

one twenty-eighth of the body length. The straight intestine is relatively wider

in the male.

The female dimensions vary considerably with age. The adult is 83 to

97 mm. long, with a maximum breadth of 0°36 to -37 mm. The head is 0°2 mm.

wide, and the cloacal region 0°12-:15 mm. The tail is 0-35 to -7 mm. and bears,

like the male, a pair of subterminal papillae, 0-01 mm. long. The cuticle is

13-19 ». The nerve ring is about 0-21 mm. from the head end. The anterior

part of the oesophagus is about 0°28-:38 mm., and the longer succeeding portion

1:7-2'1 mm., 7.e., about one forty-sixth of the body length. The vagina is much

coiled in the adult, extending forward almost to the anterior end, then bending

' back and curving around the position of the vulva, ending in a muscular enlarge-

ment from which a narrow tube leads to the exterior. The vulva in the adult

female divides the body from head to tail in the ratio 1:15, in young females

the ratio is 1:12. The vagina leads into the uterus and this divides into two uteri

which become continuous with the oviducts towards the posterior end. The

coils of the ovarian tubes extend almost to the tip of the tail. The uterus is

packed with eggs, and among these was found one larva. The eggs are 25 » by

21-5 », and the larva 0:15 mm. long and -009 mm. wide.

The species differs from D. roemeri and Filaria australis in having sub-

terminal papillae, also in the number and arrangement of the anal papillae in the

male, and in the dimensions of the worms; from F. dentifera Linstow in the

absence of a dorsal papilla on the head, in being much shorter (especially the

males), in the position of the vulva, and in the number of cloacal papillae; from

D. capilliforme in having the oesophagus longer and differentiated into two parts,

two pairs of cephalic papillae, the nerve ring further back, tail shorter, spicules

relatively of different sizes, the vagina bending forwards and the vulva situated

further back. It differs from Dipetalonema dendrolagi in the shorter length,

relative lengths of two spicules, and the arrangement of the papillae in the

cloacal region.

DIPETALONEMA ROEMERI (Linstow)

Figs. 8-13

Specimens have been examined from Macropus major (knee joint),

M. robustus (knee joint and in body cavity), M. melanops, M. dorsalis (knee

joint), M. parryi, M. ruficollis (tail muscles) and in Onychogale frenata.

These agree with Linstow’s description, but in view of the large number of

specimens examined, his account can now be amplified. As Baylis (1925) has

noted, the larger spicule consists of a cylindrical proximal portion and a needle-

like distal portion with which is associated inrolled alae. The number of cloacal

papillae has been found to be subject to variation, there being usually four pairs

of pre-anal, but we have found some with three pairs, others with four on one side

and six on the other. There have always been found one pair of adanal,

one pair immediately post-anal, and five pairs of lateral papillae, as well as a pair

of small papillae near the mid-line behind these.

In the male there are eight papillae around the mouth, arranged in pairs

laterally, dorsally and ventrally as in the diagram, and in the female four single

papillae in these positions.

In the female the position of the ovarian tubes and oviducts varies with the

age of the specimen, appearing in the older ones in the anterior region, even in

front of the vulva. The oviducts pass back leading to the uteri which travel to

the posterior end of the body, and return, joining near the end of the oesophagus.

The vagina which begins soon after this junction, twists about before entering

the vulva. The position of this varies with the age, the ratio of the total body

length to the distance between the vulva and anterior end varying from 30:1 to

50:1. Females with this difference have been found either together or with the

characteristic male of D. roemeri, and their general anatomy and dimensions such

as the relation of length to thickness, the anterior end, the nerve cord and tail, are

similar. The vulva, moreover, in almost all cases bears the same relation to the

oesophagus, extending forward from the posterior end for one-half to one-quarter

the length of the latter organ.

D, roemeri was described originally by Linstow (1905, 356-8) from material

collected from the subcutaneous tissue of Macropus antilopinus Gould. No locality,

except Australia, was given. The range of this species is the Northern Territory.

Linstow quoted some references to Filaria websteri, but remarked that no descrip-

tion of it had been published.

In the catalogue of the Royal College of Surgeons, London (1830-37), there

is reference to the Filaria macropi majoris, worms found in the capsular ligaments

412

of the knee joint of a kangaroo. Diesing in 1851 altered the name to F. macropodis

gigantet. Cobbold (1879, 433) renamed it F. websteri after its discoverer and

mentioned that Bancroft had also found it in the great kangaroo. The latter

sent much parasitic material to Cobbold from Queensland, and no doubt this

record relates to material from that State. Bennett, in his “Wanderings in New

South Wales” (1, 1834, 293), reported finding long thin white filariae encysted

in the knee joint of M. major in New South Wales. Fletcher (P.L.S., N.S.W.,

8, 1883, 388) found F. websteri in the same species, also from New South Wales.

Other authors (e.g., Molin, Linstow) have referred to some of the foregoing

occurrences. Railliet and Henry in 1910 (C.R. Soc. Biol., 68, 1910, 251) suggested

that the species might belong to Onchocerca. Yorke and Maplestone (1926, 395)

placed it under Dirofilaria. T. L. Bancroft (‘lrans. Inter. Med. Congr. Austr.,

1889, 50; Austr. Med. Gaz., 12, 1893, 258) also referred to the parasite from

kangaroos, undoubtedly Queensland occurrences. Crisp (P.Z.S., 1853, 68)

mentioned the presence of Filaria sp. in the knee joint of a kangaroo. Johnston

and M. J. Bancroft (P.R.5, Queensland, 32, 1920, 45) referred to its occurrence

in the knee joint of Macropus parryi and M. giganteus in the Burnett River

district, embryos having been taken from the blood of the former.

In spite of the numerous refercnces to the parasite, no information regarding

it has ever been published, apart from its location in certain species of kangaroos.

Its specific name is consequently a nomen nudum, D. roemeri is undoubtedly the

same parasite, as our expericnce has shown that it commonly frequents the knee

joint of many species of Macropus, including the type host for F. websteri.

Accordingly, we consider that the valid name should be D. roemeri (Linstow )

instead of Dipet. websteri (Cobbold), which has no nomenclatorial standing.

DIPETALONEMA sp. (? D, RoEMERI)

Specimens from the coelome of a tree kangaroo, Dendrolagus lumholeu, are

all immature females. They are from 6-3 to 9:5 ems. long and 1-38 to 1:69 mm.

in maximum diameter. The rounded anterior and posterior ends taper a little,

the head being about 0-107 mm. broad and the width in the region of the anus

0-15 to -2 mm. The distance from the anterior end to the nerve ring is about

0°42 mm.

The head has no lips or teeth and only two pairs of small lateral papillae.

The walls of the most antcrior portion of the oesophageal tube are slightly

chitinised. The wide oesophagus is 2°7 to 3-1 mm. long, but is not straight. The

intestine is wider, and can be seen by the naked eye as a brown-green line passing

down almost to the anus. It narrows suddenly about 0-2 mm. from the anus,

with which it is connected by a narrow tube. The tail is very short, 0°13 to

*21 mm. long, and bluntly conical.

There is in these young specimens no sign of ovarian tubes, but the uterus

and the vagina can be distinguished in the anterior part of the body. The vulva is

0-54 to 6 mm. from the anterior extremity.

This must be regarded as an immature form, but its general anatomy, length

and thickness agree most closely with those of D. roemeri, The oesophagus is,

however, wider and somewhat sinuous.

Lumholz in 1884 (P.Z.S., 1884, 409) referred to the presence of parasitic

worms in the subcutaneous tissues of this tree kangaroo, which he discovered in

Northern Coastal Queensland.

Dipetalonema rarum n. sp.

Figs. 17-19

Specimens from Onychogale frenata comprised one whole female, the

posterior end of another, and the anterior end of a male. They were taken from

small subcutaneous nodules.

The worms are relatively thin and elongated, the female being 51-5 mm. long

and 0-187 mm. maximum diameter. ‘The head is rounded, bearing four lips and

four small papillae; it is 0-126 mm. wide in the female and 0°059 mm. in the

male. The tail is tapering, ending in a rounded point, and bears two rather large

subterminal papillae. Across the anus the body width is, in the female, 0°09 mm.

The tail is 0-27 mm. long. The oesophagus is 3:15 mm. long in the female and

2-7 mm, in the male. From the anterior extremity to the nerve ring is 0-252 mm.

in the male, and 0-12 mm. in the female.

The testis tube starts with a bulb-like portion near the posterior end of the

oesophagus and continues to a coiled part about the middle of the body, where it

enters the vesicula seminalis; the rest of the body is missing just beyond this level.

The ovarian tubes extend almost to the anus; the two uteri unite a little

behind the vulva, one of them being much bent just before this junction. The

vagina is slightly coiled, then straight for a short distance before ending in a

muscular bulb from which a narrow tube leads to the exterior. The vulva is

just behind the posterior end of the oesophagus, being 3°55 mm. from the

anterior end.

There is some difficulty in classifying this worm as the posterior end of the

male is absent; the head, and the posterior end of the female, indicate the genus

Dipetalonema; the papillae of the head and the position of the vulva do not agree

with any species so far described.

Plimmer (1912a, 407; 1912b, 137) referred to finding microfilariae in the

blood of Onychogale frenata in the London Zoological Gardens, but originally

from New South Wales. The adult worms occurred in the body cavity of the

mother and of the foetus within the pouch. The species may, perhaps, have been

D, spelaea.

DIPETALONEMA SPELAEA (Leidy)

Figs. 20-24

Leidy, in 1875, gave an account of this species from a “whallabee” as

Filaria spelaea, Linstow (1897) described a parasite from a rock wallaby

(Petrogale) as Filaria australis, Breinl (1911) described a worm from the body

cavity of Trichosurus vulpecula as F. trichosuri. Leiper (P.Z.S., 1919, 620) |

115

recorded F. australis from a wallaby in London Zoological Gardens. Walton

(1927, 111-113) re-examined Leidy’s material and found it to belong to the same

species as Linstow’s, hence Leidy’s name should stand. Baylis (1925) described

a filariid from the common opossum, Trichosurus vulpecula, which resembled

F. australis Linstow (or F. spelaea), except that the major spicule was much

shorter and there was a difference in the anal and the caudal papillae, but decided

that his material belonged to Linstow’s species which he placed in Acanthocheilo-

nema. Boulenger (1928) stated that he had examined specimens from Hal-

maturus sp. (i.e., a wallaby) which agreed very closely with Linstow’s, but not

with Baylis’s description. He concluded that Baylis was dealing with a form

closely allied to, but distinct from, Linstow’s species. Oldham (1933, 30) listed

the parasite as Setaria spelaea, as also did Railliet and Henry (1911). Thwaite

(1927, 465) republished Leidy’s account.

In 1934 Baylis published a list of synonyms of Dipetalonema spelaea (Leidy),

including F. australis Linstow, F. trichosuri Breinl, 1913, and Acanthocheilonema

austvale Baylis, 1925. He stated that the most important difference lay in the

length of the major spicule, and he assumed that this feature was variable within

the species.

We have examined numerous worms from Trichosurus vulpecula and from

Petrogale penicillata, and find that in males from the latter host the major spicule

is always long, agreeing with Linstow’s account, but that in .those from

Trichosurus it is short, agreeing with Breinl’s description. The difference in

size, moreover, is so great that we are unable to agree with Baylis in his identifica~

tion, and we agree with Boulenger that there are two closely allied species

(1) Dipetalonema spelaea (Leidy) ; found in the body cavity of Petrogale

penicillata. Synonyms: Fuilaria spelaea Leidy, 1875; F. australis

Linstow, 1897; Setaria spelaca Railliet and Henry, 1911; Acanthocheilo-

nema spelaea Walton, 1927; Dipetalonema australe Boulenger, 1928.

(2) Dipetalonema trichosuri (Breinl); found in the body cavity of

Trichosurus vulpecula. Synonyms: Filaria trichosuri Breinl, 1913;

Acanthocheilonema australe Baylis, 1925; Breinlia trichosuri Yorke and

Maplestone, 1926.

We have also found males corresponding to Linstow’s and to Boulenger’s

description from the subcutaneous tissues of Dendrolagus benettianus, a tree

kangaroo from North Queensland.

Parasites belonging to Dipetalonema. spelaea are long thin worms with

rounded anterior end and tapering tail. The cuticle is marked with definite trans-

verse striations which are. close together. The male is about 11 to 12 cms. long,

with maximum diameter of 0°32 mm.; the female is 23 to 24 cms. long with a

maximum diameter of 0°66 mm. There are two large and four small papillae

on the anterior end; the mouth leads to a short vestibule surrounded by a chitinous

ring. The oesophagus is not divided into two parts; in the male it is 1-9 mm.

116

and in the female 1:55 mm. long. The nerve ring is about 0°246 mm. from the

anterior end in the male, and 0:28 mm. in the female. The intestine is rather

narrower than the oesophagus and is straight. The tail is long, 1-3 mm. in the

female, 0°86 mm. in the male.

The spicules are unequal, the longer, 1-01 mm., is cylindrical proximally,

and then flattened out, the distal half of its length being needle-like, curved and

tapering. The smaller is about a quarter of its length, 7.¢e., 0°25 mm., and has a

massive proximal part and a spatulate distal part rolled at the edges. There is

an accessory piece projecting back from the distal end. Only three pairs of pre-

anal and three pairs of post-anal papillae were distinguished. The tail is in a

spiral of two or three turns.

The vulva is 5-1 mm. from the anterior end, and is associated with a pyriform

muscular bulb from which the vagina leads back, more or less coiled according

to the age of the specimen, to the uterus which divides into the two branches

after a short distance (1°7 mm.). It is opisthodelphous. The ovarian tubes do

not extend to the anal region.

This species is somewhat like Filaria trichosuyi but is distinguished from it by

the length of the major spicule and the position of the vulva, which in Breinl’s

specimens is further forward.

It differs from F. dentifera Linstow in the absence of a dorsal head-papilla,

relative sizes of the spicules, and the position of the vagina.

117

In general anatomy and measurements the present specimens are to be

identified with Linstow’s F. australis, although only three pre-anal and three

post-anal papillae have been detected. The female of F. spelaea, as described by

Walton 1927, agrees with F. australis, so Leidy’s specific name should, as Walton

points out, take precedence. As the specific name is the plural of a Latin sub-

stantive and not an adjective, we have not altered it to agree with the genus.

Eisig (Z. f. wiss. Zool., 20, 1870, 99-102) gave an account of Vilaria sp.

from the pericardium of Halmaturus bennetti in the Ileidelberg Zoological

Gardens. Only females, 90-100 mm. in length, were present. There were stated

to be two rows of papillae, each with six, at the head end, and the oesophagus

was reported to be one-fortieth of the total length. One of us has pointed out

(Johnston, 1909, 518) that the host is a Tasmanian wallaby, Macropus ruficollis

var. bennetiw. The arrangement and number of the head papillae prevent us from

assigning the species to any of the filariids described from Australian marsupials.

D. roemeri and D, tenue seem to be nearest.

DIPETALONEMA TRICHOosURI (Breinl)

Fig. 25

We have examined many specimens of this species from the common opossum,

Trichosurus vulpecula, from Queensland, including a female from Breinl’s type

materia!, and find them to agree with Breinl’s PF. trichosuri in every way except

that there appears to be only one pair of subterminal papillae and the tail ends

in a small median papilla. It is to be distinguished from D. spelaea by the position

of the vulva and the relative lengths of the spicules; and from F. dentifera by the

absence of dorsal head-papilla, in the shape of the spicules, and in the number

of cloacal papillae. The spicules of this species are shown in fig. 25.

Yorke and Maplestone (1926, 400) published figures (fig. 273) and made

the species the type of a new genus Breinlia, but Baylis (1934, 551) and sub-

sequent workers regard the latter as a synonym of Dipetalonema.

Scott (P.Z.S., 1926, 237) reported finding filarial larvae in an opossum,

Pseudochirus lemuroides, in the London Zoological Gardens. The habitat of the

host is north-eastern Central Queensland. Linstow (1898, 460) described

Lilaria dentifera from the body cavity of Phalangista (= Trichosurus) vulpecula,

collected by Semon in Queensland—probably in the Burnett River district. Stiles

and Hassall (Index Cat. Med. Vet. Lit. Roundworms, 1920, 466) have, in error,

quoted the host as Trichiurus vulpecula, The parasite has not been satisfactorily

placed generically.

Dipetalonema annulipapillatum n. sp.

Figs, 26-29

Only males of this species were found; specimens being obtained from the

knee joint of Macropus dorsalis, the coelome of M. ualabatus and the sub-

cutaneous tissue of Onychogale frenata.,

118

It is a long thin worm, 5 to 7 cms. long, and with a maximum breadth of

0-2 to 0-3 mm.; the tail is coiled in a tight spiral of four to six turns; the anterior

and posterior ends are rounded, the anterior having two lateral epaulette-like

structures, and the posterior with a median terminal and two subterminal papillae.

The tail is about 1-1 mm. long. The papillae on the anterior end are difficult to

distinguish, but there appear to be two large laterals and four smaller ones around

the mouth. The nerve ring is about 0°25 to ‘27 mm. from the anterior end. The

mouth is situated in a depression at the anterior end; the oesophagus is 1-6 to

2 mm. long, and the intestine, starting with a slight bulge, is narrower.

The testis tubule begins just posterior to the commencement of the intestine.

The vas deferens can be traced to the beginning of the cylindrical proximal end

of the larger spicule. The latter is about 0°4 mm. long, and the distal part is

spatulate with rolled edges, and ends in a blunt point. The shorter spicule is

0-3 mm. long and is broad and spatulate, forming a groove for the longer. The

cloacal region is somewhat elevated and with it are associated several papillae

arranged in a ring, consisting of three pairs of peri-anal, one pair of post-anal, and

one pair of pre-anal. This is a different arrangement from that in any species

of Dipetalonema described hitherto.

to 1:25 mm. from the posterior end. The tail tapers and is curved, the end being

bluntly pointed; there are two very small subterminal papillac.

The ovarian tubes do not extend to the anal region. The two uteri pass

forward to the region of the vulva, where they are united into a single uterus

The following specimens have not been fully examined because they could

not be cleared sufficiently:

and has four peri-oral and two large and low lateral papillae. The intestine

narrows a short distance before the anus. The tail is short and bluntly pointed,

0-154 mm. long, and ends in a narrower part like a huge papilla (figs. 34-35).

(2) From the peritoneum of Trichosurus caninus: two worms were found

which, judged by the absence of specialization in the anal region, are females.

They are about 7 cm. long, 0-88 mm, in thickness, There are four to six peri-oral

papillae. The head is 0°15 mm. across (fig. 36). The tail is short, in one

specimen ending in an elongated portion, like the one described above. The anus

lies between two papillae, 0-099 mm. from the tip of the tail (figs. 36-37).

seen, nor can any details of the anatomy be distinguished.

We record the occurrence of Dipetalonema sp. in the knee joint or in the

coelome of the rock wallaby (Petrogale xanthopus Gray), euro (Macropus

robustus Gould), and kangaroo (Macropus major Shaw) of the northern

Flinders Ranges and adjacent regions in South Australia, but, unfortunately,

specimens are not now available to determine whether they belong to D. roemeri

or D. spelaea, or to both.

ABORIGINAL MESSAGE STICKS FROM THE NULLABOR PLAINS

By C. P. Mounrrorp, Acting Ethnologist, South Australian Museum

[Read 9 June 1938]

This brief paper places on record the description of six message sticks, five

from the Nullabor Plains and one from Eucla, he significance of three out of

the six sticks, i.¢., figures 1, 6, and 7, is also given.

1 am indebted to Mr. Allen Musgrave for having, at my request, collected

from the natives of the Nullabor Plains the sticks shown in figures 1, 5, 6 and 7,

and having obtained the meanings of the above-mentioned three; also to Mrs. J.

White, and Miss A. Lock for the loan of those shown in figures 10 and 3

respectively.

P J DESCRIPTION

Figure 1 pictures a message stick, which was a communication from the

Karonie to the Ooldea tribe. The following is the meaning obtained from the

possessor of the stick.

Column 1 (fig. 2) The small dots are the “spinifex” natives“ who are

travelling towards, and expected at Cook before many days. The con-

centric circles, H, J, K, and L indicate the water-holes on which the

travelling party will depend. H is called Mulgeru; J, Nilida; K,

Mulunga; and L, Wadiga.

Column 2 A group of natives who are camping at Tarcoola.

Column 3 The aborigines at Ooldea.

Column 4 A second party of “spinifex” natives, who are expected to arrive

at Cook in advance of those indicated in Column 1. M, N, O, P

probably refer to water-holes, although this was not specified.

It is interesting to notice that only those natives who are obliged to travel

over the practically waterless desert of the Nullahor are associated on the message

sticks with the water-hole symbols,

Column 5 A small party of both sexes who have already arrived and are

temporarily camping at Cook.

The stick was 21 cm. in length and 2 cm. major diameter. It was circular in

section, tapering down to a blunt point at either end. When received it was

wrapped in a fragment of old clothing, and bound with’ European string. The

pattern had been incised with an engraving tool about 2 mm. in width.

bed

Q) ‘Atorteines who live in the inhospitable and unexplored novtheed enre et the

Nullabor Plains,

@) The natives, unaffected by European contact, used the front incisor toath of the

opossum, still in place in the skull of the animal, as an engraving tool. This is used in a

similar manner to that employed by a European craftsman, except that the aborigine,

not having a handle on his tool, that can be rested against the palm, has to exert the

necessary engraving force with his finger tips. The writer has observed an aborigine of

the Ngada tribe of the Warburton Ranges of Western Australia, whilst he was engraving

a design on the back of a spear-thrower, and the regularity of the design and the skill

displayed in the handling of the small awkwardly-shaped engraving tool was remarkable.

Trans. Roy. Soc. S.A., 62 (1), 22 July 1938

123

Figure 3 was collected by Miss Lock while in charge of the Ooldea Mission

Station. The engraved design, the meaning of which was, unfortunately, not

obtained, is shown in figure 4. The stick was 20 cm. in length, somewhat cigar-

shaped, with a major diameter of 21 mm. Mr. N. B. Tindale showed me an

aboriginal drawing from the above locality which was almost identical with O,

figure 4. The meandering line in this case represented the ancestral snake, Kanba,

and the dots, placed symmetrically on either side, the eggs of that reptile.

The message stick depicted in figure 5, had been engraved with a spiral

pattern of transverse marks which started at the three cuts at C, and terminated

at the two cuts at O, X. When received, the design was completely obscured by

a wrapping of woollen thread of European manufacture. This example was

11 cm. in length, 6 mm. maximum diameter and had been cut and smoothed from

a twig of circular section by means of a steel tool.

Figure 6 was obtained from a locality on the Trans-Australian Railway

Line approximately on the border of South and Western Australia. Three

tribal groups are indicated: one’ from Laverton, a town some 200 miles north,

one belonging to the Muramul tribe, and the other, the people whose territory

is adjacent to the Karonie Mission Station, which is situated adjacent to the rail-

way line and some 60 miles east of Kalgoorlie.

124

The meaning, as obtained from the sender of the stick, is as follows :—

B, figure 7, is the sender of the stick, and A the Karonie railway dam. (The

use of the U-shaped symbol for a dam is noteworthy.) The line of dots, 1 E,

represents the aborigines who reside permanently at the Mission Station; line

D, the end of which terminates at one limb of A, those who “sit down along

railway line,” i.e., camp beside the railway line. The group of natives from

Laverton is indicated by the line C, while G refers to the Muramul tribe,

which sometimes visit the Karonie Mission Station. M symbolizes the above

Mission.

The stick (fig. 6) is circular in section, 25 cm. long, and 13 mm. major

diameter, tapering to a blunt point at both ends. ‘The lines of dots, which are

arranged spirally, had been burnt in, probably by a heated piece of metal, although

the glowing end of a small fire stick is used for a similar purpose by the tribalized

natives who live to the north in the Mann and Petermann Ranges. When collected,

the stick was carefully wrapped in a discarded piece of clothing and bound with

string.

In figure 8 the cuts above F (fig. 9) are the aborigines at Ooldea. The long

incision F is the Ooldea soak,“ while those below this symbol indicate unspecified

individuals, as do the marks above symbol G. The latter rciers to the Mission

Station at Ooldea, and the symbols below that point are a message to the recipient

of the stick that the missionary at Ooldea only gives one meal a day, and that

only of wheat porridge.

This stick is of circular section, and slightly curved, and is 25 cm. long

and 17 mm. diameter. The cuts forming the pattern had been made with a

steel knife.

Figure 10 originally belonged to an aborigine whose tribal country was

adjacent to the now deserted Eucla telegraph station. The stick resembles those

collected on the Trans-Australian railway line, and for that reason is included.

This specimen is somewhat longer than the other examples described and has

a mass of spinifex gum attached to one end of the stick. The length is 25 cm., and

the diameter 16 mm, The design consists of more or less parallel engraved lines,

and rows of dots, which extend the wholc length of the stick. A steel tool had

been used to produce these marks.

Discussion

Message sticks are known over the greater part of Australia. Roth (1)

figures fourteen message sticks obtained from the aborigines of north-western

QOucensland. The associated meanings were given for the majority of those

figured.

Love (2) writes of the message sticks of the Worora tribe of North-West

Australia. He mentions that the sticks are crudely made and appear to act more

as passports than actual conveyors of messages.

@) The present camping place of the aborigines of this district. The name “soak” is

an outback term for a water catchment filled with sand.

125

The writer has been shown carved message sticks by the aborigines of

Melville Island which, according to the aborigine possessing them, figure

the locality from which the stick originated, a request for provisions, and the

mark of the sender himself.

Spencer and Gillen (3), however, claim that message sticks of the type

described in this paper, and also by Roth and Love, are not used by the aborigines

of Central Australia. The extent of the area in which message sticks are not

used is unknown, but it seems likely that Spencer and Gillen’s observation would

only apply to the Central parts of the continent.

Although one often hears of cases where natives have received and deciphered

message sticks, conveyed to them by Europeans who themselves were unaware

126

of the significance of the symbols, the writer has been unable to locate any one

such case, even after considerable correspondence. Roth describes in detail the

methods in use in his area for the transmission of the message, and both Love

and Roth agree that the engraved design is no more than some kind of mnemonic

aid, or form of passport.

It is likely, however that certain standard designs are used for specific pur-

poses, such as notifications or invitations for forthcoming ceremonials. The sig-

nificance of such sticks, even when presented without a verbal message, would be

apparent to the recipient.

SUMMARY

This paper places on record the details of six aboriginal message sticks, five

from the Nullabor Plain, adjacent to the Trans-Australian railway line, and one

from Eucla.

LARVAL TREMATODES FROM AUSTRALIAN TERRESTRIAL AND

FRESHWATER MOLLUSCS

PART IV CERCARIA (FURCOCERCARIA) MURRA YENSIS N.SP.

BY T. HARVEY JOHNSTON AND E. R. CLELAND

Summary

Cercaria mutrayensis was one of the commonest larval trematodes present in Limnaea lesson;

gathered from the River Murray near Tailem Bend. In May, 1937, fourteen of 119 specimens gave

off these cercariae in the aquarium; in June only five of these snails, all uninfected, were obtained;

in early December eight out of 135 were found infected ; in March, 1938, eight out of 41 ; and in

April six out of 48. In early December, during an excursion to Swan Reach, River Murray, under

the auspices of the newly-formed Tate Society, we collected 439 specimens of the Limnaea, 200 of

which gave off these cercariae in the aquarium.

LARVAL TREMATODES FROM AUSTRALIAN TERRESTRIAL AND

FRESHWATER MOLLUSCS

PART IV CERCARIA (FURCOCERCARIA) MURRAYENSIS n.sp.

By T. Harvey Jounston M.A., D.Sc, and E. R. Creranp, M.Sc.,

University of Adelaide

[Read 9 June’ 1938]

Cercaria murrayensis was one of the commonest larval trematodes present

in Limnaea lessoni gathered from the River Murray near Tailem Bend. In May,

1937, fourteen of 119 specimens gave off these cercariae in the aquarium; in June

only five of these snails, all uninfected, were obtained; in early December eight

out of 135 were found infected; in March, 1938, eight out of 41; and in April six

out of 48. In early December, during an excursion to Swan Reach, River

Murray, under the auspices of the newly-formed Tate Society, we collected 439

specimens of the Limnaea, 200 of which gave off these cercariae in the aquarium.

The parasites could be recognised easily when the tube containing them was

held against the light, the greater number maintaining a characteristic resting

position (fig. A), suspended in the water. In this the tail stem was usually per-

pendicular and the two furcae were separated by an angle of about 120°. The

proximal part of the tail stem was bent and in line with the body, making a con-

siderable angle with the rest of the tail. By far the greater number of cercariae

were motionless at any one time, and the resting period usually varied between

five and thirty seconds. This inactivity was broken by short bursts of movement,

and the cercaria would move rapidly tail foremost (fig. B) twisting itself spirally

and varying the rate of speed. As the greater number were hanging with the

tail stem more or less perpendicular, the general movement was upwards, but

could occur in any direction, the latter sometimes changing.

In measuring cercariae, the method outlined by Cort and Brackett (1937)

was followed and the material killed by adding to it an equal volume of boiling

10% formalin. Specimens were examined and the following are the measure-

ments of 30: length of body 1384-185 », average 158 4; breadth of body across

ventral sucker 32-46, average 37; anterior tip of body to centre of ventral

sucker 77-131», average 100,; length of tail stem 161-208», average 188 p;

width of tail stem 24-34», average 27°54; length of furcae 154-200 p, average

173 4; length of anterior organ 45-60 p, average 544; length of posterior sucker

22-29 p, average 25-9; breadth of posterior sucker 22-27°5 », average 25°7 u.

The body was finely corrugated, and thus it was extremely difficult to see

the body spines clearly. The large anterior organ showed no differentiation into

two parts, and the well developed ventral sucker lay just behind the middle of

and concentrated into two groups lying near the junction of the intestinal caeca.

About twelve large forwardly directed spines occurred on the highly con-

tractile anterior tip in front of the mouth (fig. 3). Surrounding this region was

a flattened spineless area on which opened the mouth and the ducts of the gland

cells. This was succeeded by a collar of spines of varying sizes arranged some-

what irregularly in from five to seven rows, with the largest spines in front.

Another spineless area separated these from the much smaller spines of the general

body surface. These latter, larger on the ventral than on the dorsal surface,

were arranged irregularly just below the collar, with a tendency to form rows

on the ventral surface, and behind this they were grouped in nine double rows,

the last being on a level with the middle of the ventral sucker. The spines posterior

to this were arranged irregularly on the ventral surface, and were much more

numerous at the posterior end near the tail. Two irregular rows were present

on the ventral sucker. We were unable to ascertain whether there were any

minute spines on the tail stem, but they appeared to be present on the furcae.

The mouth was subterminal, the pre-pharynx short and the pharynx well

developed. The oesophagus bifurcated just in front of the ventral sucker into the

well-defined caeca, which were characteristically bent and reached almost to the

bladder. hey were filled with a clear refracting substance which was not con-

tinuous but separated into masses, so that the intestine appeared at first sight to

be composed of a few large cells. It stained well with netitral red.

The four gland cells (figs. 1, 5) stainable with nile blue sulphate lay

behind the acetabulum, ventral to the caeca. They were coarsely granular and

slightly lobed with large clear nuclei, and arranged in two pairs, those in the first

pair being somewhat tandem, and those in the second opposite. The ducts passed

forwards in two pairs, following the course indicated, and in all but fully extended

specimens were twisted in the region of the pharynx. After entering the anterior

organ they became much enlarged, then narrowed before opening dorso-laterally

on the circumoral spineless area.

The genital primordium consisted of a mass of undifferentiated cells lying

between the ends of the caeca and the bladder. The nervous system was repre-

sented by an H-shaped mass of tissue lying posterior to the pharynx. Longi-

tudinal and circular muscle fibres were present in the tail stem, and there were

about forty caudal bodies of varying size with a tendency to become arranged in

indefinite groups.

From each of the antero-lateral borders of the small bladder, mushroom-

shaped when fully distended, arose a main excretory duct. Each was slightly

coiled and proceeded upwards and outwards to about the middle of acetabulum,

where it doubled back and, on a level with the posterior margin of the ventral

sucker, gave rise to an ascending and descending branch. The flame cell formula

was 2 X (6 + 2) = 16. Of the three flame cells connected with the anterior

tubule, one lay alongside the anterior organ, the second near the pharynx, and

130

the third just in front of the acetabulum. Of the three connected with the

descending branch, one was just posterior to the ventral sucker, the second about

midway between this and the posterior end, and the third alongside the bladder.

The descending tubules passed into the tail stem, each bearing two flame cells.

The island of Cort was small, and the main excretory tube passed down the

centre of the tail stem to divide into two just before reaching the furcae. Each

branch opened on the edge of the furca (fig, 2) about half-way along its length.

The sporocysts present in tangled masses in the liver were very hard to

separate. They were attenuated, one end being pointed with a birth pore just

behind the tip, and the other end bluntly rounded. They contained numerous germ

balls and developing cercariae. Older sporocysts had a thin wall formed of

cuticle and sparse, flattened epithelial cells (fig. 8), the latter being several layers

deep at the end of the sacs. Germ masses and mature germ cells were typical.

Cort and Brackett (19374) gave a bricf resumé of the Strigeid cercariae

obtained from Douglas Lake, Michigan, and of these our specimen resembles most

closely C, flexicauda and C. yogena, The behaviour in free life of our species

was almost identical with that of the former (Cort and Brooks, 1928), and its

average lengths of body, tail stem and furcae respectively were 158 », 188 », 173 p,

compared with 170 yw, 254 » and 226 in C. flexicauda, and 173 », 236 pand 221 p

in C. yogena. Our species was considerably smaller than both the American forms

and the furcae and tail stem both approximated more nearly to the length of the

body. The spination resembled most closely that of C. yogena, and the pigmen-

tation charactcristic of the American form was almost identical with ours, though

as yet no pigmentation has been seen in the tail stem. The caudal bodics and

excretory system resembled those of C. flexicauda, while differing from those

of C. yogena, There was no ciliation of the main collecting tubes as in the latter

131

and the position of the flame cells differed. The anterior organ was the same

length as in C. flexicauda, but the ventral sucker was smaller, being 26 » long

in our form and 35 in the American.

Cort and Brackett (1937b) published a paper on the identification of

Strigeid cercariae, utilizing differences in their behaviour during free life. Before

receiving their article we had already noticed such behaviour in our specimens,

and were able to distinguish the species with the naked eye from amongst a

collection of cercariae.

Wesenberg-Lund (1934) drew attention to that group of Strigeid cercariae

characterised by the presence of four penetration gland cells behind the ventral

sucker, which had been mentioned by Cort and Brooks (1928). ‘To this Proalaria

group of pharyngeal, longifurcate, distome cercariae of Miller (1926) our species

belongs, and appears to us to be a typical member, having for its intermediate

stage a Diplostomulum present in the eyes of certain freshwater fish.

We suggest the name Cercaria murrayensis for this Proalaria larva and

propose to give an account of experimental infections of various fish in a later

paper.

ON A NEW SPECIES OF POTORUS (MARSUPIALIA) FROM A CAVE

DEPOSIT ON KANGAROO ISLAND, SOUTH AUSTRALIA

BY H. H. FINLAYSON

Summary

To the generosity of the late Dr. A. M. Morgan, the South Australian Museum owes a collection of

mammal bones taken in the so-called Kelly's Hill caves on Flinders Chase in the south-western

portion of the island. While the collection is an interesting one as indicating the former presence on

the island of mammals which are now either absent or excessively rare, all the species represented,

save one, are identical with, or closely related to, those indigenous to the adjacent South Australian

mainland. The exception is found in a single skull of a rat-kangaroo, which is clearly an

undescribed species of Potorus, allied to the West Australian P. platyops.

ON A NEW SPECIES OF POTOROUS (MARSUPIALIA) FROM A

CAVE DEPOSIT ON KANGAROO ISLAND, SOUTH AUSTRALIA

By H. H. FInLtayson

Hon. Curator of Mammals, South Australian Museum

[Read 9 June 1938]

Piates V, VI and VIT

To the generosity of the late Dr. A. M. Morgan, the South Australian

Museum owes a collection of mammal bones taken in the so-called Kelly’s Hill

caves on Flinders Chase in the south-western portion of the island.

While the collection is an interesting one as indicating the former presence

on the island of mammals which are now either absent or excessively rare, all the

species represented, save one, are identical with, or closely related to, those

indigenous to the adjacent South Australian mainland. The exception is found in

a single skull of a rat-kangaroo, which is clearly an undescribed species of

Potoroiis, allied to the West Australian P. platyops.

On searching other collections of Kangaroo Island material in the Museum,

a second skull of the same animal, with a part skeleton, has been found. This

was forwarded to the Museum from the same cave in February, 1926, by Miss

Edith May.

CRANIAL CHARACTERS

Both skulls are damaged and that from the Morgan collection is without a

mandible. By a fortunate chance, however, the damage has not affected the same

areas in both skulls, so that taken together they give an almost complete version

of the cranial anatomy of the animal. Both skulls are from mature or even aged

aninals, with the secator and M+ in place, and in both the molar crowns show a

considerable amount of wear, One is appreciably larger than ihe other (see

table), and for purposes of comparison with the British Museum specimen of

P. platyops, measured by ‘Vhomas (1), this has been assumed to be a male also,

though, of course, it is by no means certain that such was the case.

The skulls are very small and delicate, and the animal evidently shared with

P, platyops the distinction of being the smallest member of the subfamily, and,

indeed, of the whole of the Macropodidac, with the exception of Hypsipymnodon.

In general shape the skull is quite Bellongia-like, roughly comparable to B. peni-

cillata for example; the shortened muzzle, smooth outlines and absence of crests

making it very unlike an adult of its congener, P. tridactylus. That its place is

with Potoroiis, however, is plainly attested by the characters of the dentition

and by the structure of the muzzle region, of the zygomata and of the mandible.

The nasals are relatively shorter than in tridactylus and much more expanded

posteriorly, though less so than in platyops. Their maximum breadth goes but

133

2-2 times into their length, and their minimum breadth along their junction with

the premaxillae, 5-8 times. The general shape of the nasals is similar to that of

platyops, but both postero-internal and postero-external angles are more acute

than in the West Australian species. ‘The posterior portion of the muzzle region

is greatly expanded from side to side, but at the maxillo-premaxillary suture is

suddenly constricted, and from that point to the anterior nares the nasal chambers

are narrow and tubular, with their vertical and transverse diameters about equal.

This is a good distinction of Potoroiis from Caloprymnus, Betiongia and Aeyp-

prymnus, in all of which the anterior nares show a more or less marked deepening

from above downwards, as in the typical Macropodinae. The relative areas of

premaxilla and maxilla on the walls of the nasal chambers are about as in

tridactylus, but the sharp procumbent spur on the anterior margin of the pre-

maxillae in the latter species is absent or only slightly indicated.

The frontal and interorbital region is quite parallel-sided and remarkably

broad; even more so than in platyops, In the larger oi the two skulls the inter-

orbital width is nearly half the maximum width of the skull across the zygomata.

The supraorbital margins are smooth and rounded, but in the larger skull there

is a slight tuberosity at the site of the post-orbital process, The brain case is

deeply vaulted and very smoothly rounded, the temporal ridges but slightly

indicated, the sagittal crest absent and the lambdoids very slight. The contours

of this part of the skull are practically those of a very young tridactylus at the

M? stage.

The plane of the occiput is less oblique to the basi-cranial axis than in

tridactylus, and does not differ notably from that in some Bettongia. There is a

thin crescentic interparietal. ‘The paraoccipital processes scarcely exist as free

projecting elements, but are bent forward and closely applied to the posterior

border of the bullae, as in some Peramelidae. The alisphenoid bullae are much

more expanded than in tridactylus, but variably so in the two skulls—the smaller

having considerably the larger bullae. In this example the antero-posterior

diameter of the expanded portion is 9 mm., the transverse diameter 5:6 mm., and

its projection below the level of the lower margin of the tympanic annulus 4-2 mm.

The zygomatic arch is curiously shaped in a lateral view, The anterior root

of the malar is broad and powerful, but rapidly narrows to a thin weak infra-

orbital bar. The upper margin of the squamosal portion is feebly concave and

it slopes down to the posterior root, though much less steeply than in tridactylus.

The squamosal makes a wide contact with the frontal.

The posterior palate has been damaged in both skulls, but the pterygoid

fossae seem to have been shallower than in tridactylus and, therefore, much

shallower than in the rest of the subfamily. The palatine vacuities are longer,

extending forward to the front of M? in one skull and the middle of M! in

another, Anterior palatal foramina very small, as in platyops.

The mandible shows the typical Poterois characters of slenderness, compara-

tively straight inferior border, a weak coronoid process meeting the alveolar

134

border at a wide angle, and a condyle relatively large, expanded from side to side,

and with its antero-internal angle produced to a spur.

DENTITION

All the teeth of the adult dentition are represented in either one or other of the

two skulls, except the upper second and third incisors, All the teeth are consider-

ably worn, and the finer detail of crown pattern in most cases lost. In the upper

series the first incisor is a comparatively short broad tooth, showing none of the

exaggcrated styliform specialization of iridactylus; it projects beyond the

alveolar margin only about 3 mm., as against 8 mm. in fridactylus, but resembles

its larger ally in that its anterior surface is nearly vertical and lacks the more

or less marked recurvature of all the other genera. In platyops this tooth is stated

to be “very long” (Thomas}. The alveoli of the missing second and third

incisors indicate minute teeth,

A single detached canine is a fairly strong functional tooth of about the same

relative proportions as in tridactylus. The secator is a reduced version of that

of tridactylus; the anterior lobe strongly developed into a subconical cusp pro-

jecting well below the general level of the blade; the outer surface strongly

emarginate and bearing two broad shallow grooves; the long axis parallel to the

basi-facial axis of the skull. The molar rows are less straight than in tridactylus,

converging gently towards M+. M? >> Mt>M&>M¥#4. ‘The crowns of all the molars

are squarer and less elongate antero-posteriorly than in fridactylus; their surfaces

smooth through wear, but originally quadri-tubercular and their pattern very

similar to tridactylus and the primitive species of Beftongia. M* a relatively

smaller tooth than in tridactylus; its crown area little more than that of the

posterior lobe of M*. The posterior lobe of M* reduced, but distinctly bifurcate.

In the mandible the incisor is a broad, somewhat round-pointed tooth, more

spatulate than in most of the Potoroinae and without the upward phalangerine

curvature of tridactylus and platyops. P4, 3-9 mm.; obscurely 2-grooved. M4,

quadricuspid, M? > M% > Mi > M4,

In comparing the skull characters of the present form with those of

P. platyops, T have had to rely entirely upon the first description of Water-

house (2), of Thomas (loc. cit., 121) and the supplementary remarks of

Bensley (3) upon the dentition. These notices, together with the single figure of

Thomas, leave the skull of platyops still very imperfectly described, and many

details which would have amplified the comparison are lacking. The chief

differences which have been brought to light may be summarized as follows:

1, the nasals in the South Australian animal are longer, less expanded posteriorly,

and with slightly different conformation of their posterior margins; 2, the inter-

orbital region is wider; 3, the palate is longer; 4, the molar rows are longer;

5, the first upper incisor is shorter; 6, the lower incisor is more specialized and

lacks some of the phalangerine characters of platyops.

135

While it is obvious that the Kangaroo Island form is closely allied to the

West Australian platyops, and possible that the first four differences might dis-

appear if adequate series of both could be measured, five and six appear to be

true structural differences indicating differing degrees of specialization. More-

over, the two localities (Kangaroo Island and Albany) are over 1,000 miles apart,

and while platyops is (or was in 1840) a living species, the circumstances of the

present find necessitate one regarding it as a fossil or subfossil form, with the

possibility of a considerable antiquity“ in post-Pleistocene time. For these

reasons I propose to distinguish it under the name Potorotis morgani with a part

skull without mandible, registered number P. 3413, and a part skull with mandible,

registered number P.168, as cotypes of the species, in the South Australian

Museum.

Associated with the larger skull is a part skeleton forwarded at the same

time. With the exception of three fragments evidently derived from a larger

animal, possibly Trichosurus, these bones arc in the same condition of preserva-

tion as the skull and show the same characteristic surface spattering (since

removed). They exhibit, moreover, morphological characters which place them

unmistakably with Potoroiis, and that they are derived from the same animal that

furnished the skull, I believe to be beyond reasonable doubt. Though I propose

to found the species, so far as diagnosis is concerned, upon cranial characters

alone, some account of the rest of the skeleton may be of interest, as those of

gilberti and platyops have never been examined, and the osteology of Potorots

as recorded, thus rests entirely upon the existing species, tridactylus, regarded by

Bensley as a comparatively specialized form.

The bones, like the skull, give evidence of considerable age in the animal

furnishing them, and in the examination which follows they have been compared

with a skeleton of a similarly aged male of tridactylus from ‘Tasmania, and with

skeletons of three other Victorian examples at varying stages of immaturity.

Wherever dimensions are given for tridactylus, however, they are derived from

the aged male alone. All dimensions in millimetres.

The fore limb

The clavicle, scapula, humerus, radius and ulna of both sides are present, but

the manus is represented only by a carpal element and some phalanges.

The clavicle has a maximum length across the are of curvature of 14:3, as

against 24-1 in tridactylus. It is of the same general form but more strongly and

suddenly expanded at the sternal extremity, and wider also below the attachment

to the acromion.

The scapula—Maximum length, 34-3; maximum breadth, 12-4. Somewhat

narrower than in tridactylus, the ratio length/breadth 2:7, as against 2:3. The

“ The appearance of the bones does not encourage this idea so far as the present

specimen is concerned. They are quite unmineralized and, when cleaned from some surface

spatterings, quite unstained and have a very “recent” look. It is possible that the animal

may have persisted on the island till quite recent times, or even still be extant there.

136

supra-scapular border more rounded, its angle with the glenoid border less acute,

and the anterior border approaching the coracoid, less decly emarginate.

The humerus—Maximum length, 31-1; distal breadth, 8-1; proximal breadth,

6:7. Agreeing closely with immature bones of tridactylus in structural features

and proportions, but the shaft relatively more slender than in the adult of that

species, and less expanded distally, The proportion of distal expansion to length

is 3:8, as compared with 3°3 in the larger animal.

The radius—tength, 38-1. Much as in tridactylus, in which the length is 51:8.

The ulna—Maximum length, 45°8. Tridactylus 64 (ca.). The shaft more

slender. somewhat rounder in section, and less flattened from side to side; taper-

ing rapidly distally to a very delicate styloid process. The anconeal process

appearing massive in comparison with the distal part of the bone, but its propor-

tion to the bone as a whole much the same in both species. Immediately distad

to the coronoid process of the notch, its lateral surface is conspicuously hollowed

out over a space of 6 mm., beyond which the surface is distinctly ridged for a

like distance—neither feature marked in the larger animal.

The proportion which the length of scapula, humerus and ulna individually

pear to the limb as a whole is exactly the same in both species.

The pelvis—The following figures give the chief dimensions of this bone in

morgani and tridactylus, respectively. The number in brackets is the quotient

obtained by dividing the maximum length by the value in question. This arrange-

ment is adopted in the succeeding sections as well. Maximum length, 54:1, 83-8;

ischial breadth, 31-9 (1-7), 54:9 (1°5); acetabular breadth, 30°5 (1-7), 50:0

(1:7); illiac breadth, 33-2 (1:6), 56°0 (1'5); length of pubic symphysis,

21°9 (2°5), 34:0 (2:5).

The pelvis presents several minor points of distinction. It is proportionally

longer and narrower, the ischial tuberosity is more developed, the illiac wing tapers

to the extremity, and the pubics along the symphysis are much narrower and more

fragile, with a corresponding alteration in the shape of the obturator foramen.

‘The epipubic of the right side has been preserved (detached) ; in shape and

relative size much as in fridactylus; its maximum length 10°7, and width 3-3.

The hind limb

This is represented by femur, tibia and fibula of both sides, quite undamaged,

and by a number of pedal elements.

The femur—The chief dimensions of this bone in morgani and tridactylus

are as follows: greatest length, 56°3, 85:4; proximal breadth across the

trochanters, 10°5 (3-3), 16:2, (5°3); diameter of head, 4:3 (12-0), 8:3 (10:3);

distal breadth, 9°6 (5°8), 14:0 (6:1); minimum (antero-posterior) diameter of

shaft, 4°0 (14-1), 7-8 (11-0).

The femur is thus in close agreement with that of the larger species in its

main proportions, but is more slender; the minimum diameter of the shaft going

2'6 times into the maximum breadth across the trochanters, as against 2:0 in

tridactylus. The disproportion between the antero-posterior and transverse

137

diameters is also greater in morgani, the bone being more distinctly compressed

from side to side.. The head is less developed, and so also is the tuberosity on

the posterior surface of the shaft.

The tibia—Maximum length, 64:1, 95-6; proximal breadth, 9°8 (6:5),

14:8 (6:5); distal breadth, 6°8 (9-0), 10-5 (9°1); minimum breadth, 2°8 (23),

5-5 (17). The structural features concerned with articulation and muscular

attachment are practically those of tridactylus in miniature. As with the femur,

however, the shaft is more slender in comparison with the extremities. Its medial

outline, as scen from behind, is slightly less sigmoid, and on the anterior border

the notch below the tubcrosity is deeper.

The fibula—In this bone the agreement in proportion is less exact, but no

considerable differences can be made out. Maximum length, 62-0, 92:7; proximal

breadth, 4:5 (13-7), 7:5 (12:3) ; distal breadth, 3-6 (17:2), 5°8 (16).

The pes—Twenty elements derived from both left and right feet are repre-

sented. Neither extremity can be reconstructed from them, but the main axis

of the left foot can be laid down sufficiently accurately to give the approximate

length of the pes.

Length of pes, 58-0, 90°5; calcaneum, 11°6 (5:0), 17°2 (5:2); second meta-

tarsal, 21:5 (2-7), 26-9 (3-4); fourth metatarsal, 25:0 (2:3), 32-7 (2:8); first

phalanx of fourth digit, 11-7 (4°9), 15-8 (5-7). In morgani the fourth meta-

tarsal makes a larger contribution to the length of the foot than in tridactylus,

presumably with a corresponding reduction in the astragalus and second and third

phalanges, and the metatarsals of the syndactylus digits also show a similar

elongation.

The changes in the appendicular skeleton, which occupy a prominent place

in the evolution of the Macropodidae from the Phalangeridac, are somewhat less

important in Potorotis than in the other genera, owing to the early adoption of

comparatively sedentary, and in the case of (ridactylus, partially fossorial habits.

Nevertheless, the specialization of the hind limb has already gone so far that

careful comparisons of the proportional dimensions of the limbs and their seg-

ments might well be expected to bring to light any considerable differences in the

phylogenetic standing of the two species under consideration. The most important

of the relationships which can be deduced from the figures are:

(1) The proportional contribution of each of the three segments to the total

length of both fore and hind limb. Under this head five out of the total

six sets of segments have been tested, and the agreement between the two

species found to be very close. The greatest divergence is in the pes,

where it amounts to no more than 3%.

(2) The length of the fore limb in relation to the general bodily size of the

animal, In assessing this relationship, I have taken the length of the

vertebral column from atlas to sacrum (inclusive) as a rough index of the

size of the animal, and expressed the length of humerus, plus antibrachium,

as a percentage of it. This gives 50% for morgani, 46% for tridactylus ;

a relative superiority of about 8% in the fore limb of the smaller animal.

138

(3) The length of hind limb in relation to the general bodily size of the animal.

Here the agreement is almost exact, the percentages being: morgant,

115% ; tridactylus, 116%.

(4) The relative disproportion in length of fore and hind limbs. It follows,

from (2) and (3), that the ratio of fore to hind limb in morgani is as

1:2°3, and in fridactylus 1:2°5. In the Phalangeridae the subequal or

superior fore limb is the rule, and the sole evidence of the retention of

primitive characters in the limbs of P. morgant is, therefore, this 8% reduc-

tion in the superiority of the hind limb, as shown by the most “advanced”

species, iridactylus.

Ribs—Twenty are represented, of which 11 are from the left side, the

absentees being the eighth and thirteenth.©? The maximum length across the

are of the first and sixth are 9-9 and 31-9, and in tridactylus 14°8 and 49-2,

respectively. They agree closely with those of the larger species.

Vertebrae—Thirty-seven elements are present, representing 4 cervicals, 12

thoracics, 6 lumbars, the sacrum, 5 precaudals, and 9 caudals. As a disarticulated

column of a sufficiently aged tridactylus is not available, comparison of a single

accessible dimension of one vertebrae in each of five groups has been made.

(The figures in brackets are the quotients of the values for tridactylus divided by

those for morgant.)

Maximum transverse width of atlas, 14-1 (1:0), 23:3 (1°6); maximum

height of first thoracic, 17-3 (1:0), 33:2 (1-9); maximum transverse width of

sixth lumbar, 6°8 (1:0), 31:2 (1°8); maximum transverse width of sacrum,

18:9, (1:0), 32°6 (1:7); maximum transverse width of second precaudal

16°3 (1:0), 28-7 (1°7).

The disproportion between the two species is greatest in the thoracic series

and is due chiefly to the exaggerated development of dorsal spines in tridactylus.

This is, no doubt, correlated with a heavier nuchal musculature, which, in turn,

is a response to the much longer and heavier head and to the greater develop-

ment of the habit of rhinal excavating.

Slernum—This is represented by the manubrium, intact. It agrees exactly

in form with the same segment in two immature skeletons of fridactylus from

Victoria, but differs from the aged Tasmanian example. In the manubrium of

this specimen two pairs of lateral processes are developed—possibly as an

abnormality, however, as the bone is warped and unsymmetrical, Maximum

breadth, 12-0 (1-0), 19-1 (1-6).

Bensley (loc. cit.), from a study of the dentition of P. platyops, P. gilbertt,

and P. tridactylus, was lead to a belief in the much more primitive position of the

former, as “a form which shows an interesting approximation in many of its dental

and cranial characters to Petaurus, suggesting an affinity with Gymnobelideus,”

etc., etc.

@?) Assuming 13 to be the normal number as in tridactylus.

139

While an intimate comparison of the skulls of morgani and platyops has not

been possible, enough has been done in this direction to suggest that the two are

upon much the same evolutionary level. It is somewhat surprising, therefore, on

extending the comparison to skeletal characters, to find a relatively close

correspondence between morgani and the much larger, (and in cranial anatomy)

more specialized tridactylus, Though there are definite minor structural differ-

ences to be seen, and minor differences in proportion have been demonstrated,

these are mostly of a kind to be associated with inferior size, weight and muscu-

lature, and surface, rather than subsurface feeding habits. The attempt to

disclose a greater residuum of primitive phalangerine characters in the smaller

animal by systematic mensuration, has served chiefly to emphasise the close detailed

correspondence of bone for bone; a correspondence which might well be further

increased if the range of individual variation could be taken adequately into

account.

On the whole (if morgani can be taken as representing platyops), it would

appear that the osteology of Potorotis as a genus is at least as stereotyped as that

of Bettongia, and that the differentiation of tridactylus from the smaller species

is a comparatively superficial and perhaps very recent change.

ON THE ECOLOGY OF THE GROWTH OF THE SHEEP POPULATION IN

SOUTH AUSTRALIA

BY J. DAVIDSON

Summary

Considerable attention has been focussed, during recent years, on the biology of animal populations.

Several investigators have studied, quantitatively, the influence of various factors affecting the

growth of populations. For each species of animals in an area, the number of individuals varies from

time to time, according to the intensity of the struggle going on between the forces which enable the

species to reproduce and the physical and biotic forces in the environment; the latter may favour the

birth rate and survival rate during certain periods and depress them during other periods. In order to

make a quantitative study of the growth of natural populations it is necessary, therefore, to obtain a

census, from lime to time, of the individuals composing the population. In a natural environment

great difficulty is experienced in obtaining reliable samples representative of the population in a

given area at the time the samples are taken. It has been shown by several experimenters, notably by

Raymond Pearl and his associates, that in the "closed" system of a laboratory experiment, the

growth of a population follows a definite course, which appears to be clearly represented by the

Verhulst-Pearl logistic curve (5). Pearl and Reed (6) applied this curve in order to interpret the

course of the growth of human populations; Belz (1) applied the same principles to the population

of Australia.

ON THE ECOLOGY OF THE GROWTH OF THE SHEEP POPULATION

IN SOUTH AUSTRALIA

I INTRODUCTION

Considerable attention has been focussed, during recent years, on the biology

of animal populations. Several investigators have studied, quantitatively, the

influence of various factors affecting the growth of populations. For each species

of animals in an area, the number of individuals varies from time to time, according

to the intensity of the struggle going on between the forces which enable the

species to reproduce and the physical and biotic forces in the environment; the

latter may favour the birth rate and survival rate during certain periods and

depress them during other periods. In order to make a quantitative study of the

growth of natural populations it is necessary, therefore, to obtain a census, from

time to time, of the individuals composing the population. In a natural environ-

ment great difficulty is experienced in obtaining reliable samples representative

of the population in a given area at the time the samples are taken. It has been

shown by several experimenters, notably by Raymond Pearl and his associates, that

in the “closed” system of a laboratory experiment, the growth of a population

follows a definite course, which appears to be clearly represented by the Verhulst-

Pearl logistic curve (5). Pearl and Reed (6) applied this curve in order to

interpret the course of the growth of human populations; Belz (1) applied the

same principles to the population of Ausiralia.

The growth of a sheep population is subject to the controlling influence of

the sheep farmer. The position in South Australia is of interest, since the genial

climate permits of the sheep leading a comparatively free life, and a century of

annual records of the sheep numbers are available. Prior to 1836, when the

Province of South Australia was founded, the inhabitants of the country were

aborigines who did not practise agriculture. Therefore, the natural vegeta-

tion was undisturbed, except for light grazing by marsupials and occasional bush

fires. The early settlers imported sheep from Tasmania and elsewhere to form

the beginnings of the sheep industry. At the end of 1838 there were 380,000

sheep in the Province. The pastoralists aimed at increasing their flocks, so as

to occupy the expanding area of grazing land which was gradually being opened

up in the virgin country. Jt was necessary to protect the sheep from natural

enemies such as wild dogs (dingoes)}, and later on from foxes and blowflies. The

introduced rabbit (Oryctolagus cuniculus) increased rapidly in numbers after

about 1870; an Act of Parliament was passed in 1875 “to provide for the

suppression of the rabbit nuisance.” It is not possible from the data available

Trans. Roy. Soc. S.A., 62 (1), 22 July 1938 J

142

to assess, quantitatively, the effect of these biotic factors on the growth of the

sheep population.

When all the areas in the Province suitable for sheep-raising had been

occupied, it would be expected that the sheep population would attain a saturation

density. The number of sheep would be determined primarily by the “permanent”

fecding value, or “carrying capacity” of the pastures; the latter would depend,

to a great extent, on the management of the pastures in this respect. Economic

factors, associated with supply and demand of the products of the sheep industry,

would also exert an influence.

The object of the present paper is to examine the annual records of sheep

numbers for South Australia, and interpret the growth of the population in terms

of the Verhulst-Pearl logistic curve.

Il Fittinc tHe Data To THE VERHULST-PEARL Locisric CURVE

The annual numbers of sheep in South Australia since 1838 are given in the

published livestock statistics prepared by the Government Statist. Records were

not taken for the eleven years 1841, 1851, 1855, 1885-8, 1893-5 and 1906, but

reliable estimates are available for these years. The number of sheep for each

year is plotted in figure 1. The average annual number for each five-year period

since 1838 is given in Table I; in each case the number is allotted to the mid-year

for the period.

The data given in Table I have been fitted to a logistic curve, having the

formula: K

Let €

143

where y= population; x=time (year); d=0; K—=distance between the

upper and lower asymptote; @= 2°71828 (base of Naperian logs); a and b are

calculated constants. The value K == 7115-3 (thousands) was calculated from

the average sheep numbers for 1850, 1865 and 1880. For each of the observed

values for y, and the appropriate values for x from 1845 to 1880 (Table I), the

K-y

values of log

were calculated. These values were fitted to a straight line

by the method of least squares for eight observations. The formula for the line

is y==a-+ bx where a = 1°351005 and b = —0'29031.

Taking the values for log ‘ when x == 1845 and 1875 respectively, and

changing these values into Naperian logarithms (N), the constants @ and b in

a— bx

1+e were calculated, by substituting the appropriate values for x and N

in the formula: N = a—bx

This gave a = 249°106686; b = 0°133693. Substituting these values in the

formula: K

y=d+

a — bx

i-+e

we obtain the calculated logistic curve 7445.3

249. 106686 — 0-133693x

1+e

The curve is shown in figure 1; the observed and calculated values for the popula-

tion (y) are given in Table I.

The curve illustrates the trend of the population up to about 1890, when the

density approximates to its upper asymptote (7115-3 x 1000). This is the

theoretical saturation density for the sheep population under the environmental

conditions obtaining up to that time. It might be expected, with a stable environ-

ment, that the future population would oscillate about this density, but the exten-

sive fluctuations after this date (fig. 1) “show that profound changes must have

taken place in the environment. These changes and their influence on the popula-

tion are discussed in the next section.

ITI Procress of TIE SHEEP POPULATION

South Australia has an area of 380,000 square miles, of which 83%, con-

sisting of the northern portion of the State, has an annual rainfall of less than

10 inches. The characteristics and distribution of the native vegetation are

primarily related to rainfall; apart from economic considerations, the availability

of food (pasture) and water are the major factors affecting the progress and

distribution of the sheep population (8).

144

The gradual opening up of the savannah woodland and sclerophyll forest

by the early settlers afforded excellent pasturage for sheep; the clearing of the

mallee lands came later with the development of wheat farming. The flocks

gradually progressed northwards into the saltbush steppe and by 1866 had

extended to about the thirtieth parallel of latitude, a northern limit determined

ANNUAL RAINFALL

Fig. 1

The sheep numbers taken from official records are shown for each year (small

black circles); the average number for 5-year periods, since 1838, are also shown

(larger, open circles). The rainfall for the years 1839-60 on the Adelaide Plains

is shown; from 1860 onwards the rainfall data are for the Lower North (Central)

districts. The shaded area shows the years in which rainfall was below the average

by rainfall and distance from the occupied areas (7). With the proclamation of

the first counties in 1842, the area under cultivation, particularly for wheat,

gradually extended; by 1891 approximately 24 million acres were under cul-

tivation (3, 7).

145

Rainfall plays a dominating part in producing fluctuations in the number of

sheep from year to year, due primarily to its effect on the pastures. In figure 1

is shown the annual rainfall for 1839-60 over the Adelaide Plains; and for 1860-

1931 over the Lower North (Central) district of South Australia. The rainfall

figures were taken from the official publication of the Commonwealth Bureau of

Meteorology, “Results of Rainfall Observations made in South Australia and

the Northern Territory,” by H. A. Hunt, 1918, 17; additional data were kindly

supplied by Mr. E. Bromley, Government Meteorologist for South Australia.

The shaded portions of the graph indicate the years and amount in which the

rainfall was below the average of 18-4 inches and 18°6 inches, respectively. The

rainfall for these restricted regions does not give a complete picture of the annual

march of precipitation over the whole of the State; but the chart shows those

years in which the State received adequate rains, and those in which it experienced

dry conditions. There is considerable agreement between dry years and thd

reduction in sheep numbers; for instance, during the periods 1895 to 1902, 1911

to 1915, and 1926 to 1930,

(a) Period 1838-1891

The population follows closely the trend of the calculated curve throughout

this period. The sheep numbers for 1838 and 1839 are dominated by importations

and fall below the calculated curve. From 1840 to 1868 they follow the curve

closely, and the dry years appear to have had little effect in reducing the popula-

tion. This may be attributed to the extensive, unoccupied country available for

grazing during this carly period. For this reason, cattle, which attained their

maximum numbers of 375,000 in 1860 and rapidly fell away again, do not appear

to have entered seriously into competition with sheep for pasture. The fall in

the population during 1869-72 is associated with the dry years, 1868, 1869, and

the economic depression which obtained during this period (3). The persistent

fall in the population during 1884-89 is related to the dry years of the 1880's;

under the influence of good rains in 1889-90 the numbers again rose rapidly. At

the end of 1891 there were 7,646,239 sheep in the State, a density which was not

attained again until forty years later. Adequate feed (pasture) appears to have

been available about 1891 to support this density for a time. Considering the

rapid fall of the population in the following years, it is evident that the pastures

could not support this density permanently. The saturation density which might

be expected from the calculated curve is 7,115,300. It is seen from Table I that

the values of the five-year averages for 1895, 1905, 1910 and 1920, lie about a

straight line drawn through the average value (6285-75 thousands) for these

four periods (the mid years 1900 and 1915 have been excluded, because they

represent the population during severe periods of drought). The average value

6285-75 (thousands) for the above periods is 856-55 thousands less than the upper

asymptote of the calculated curve. It may be concluded that the conditions

obtaining throughout these years tended to keep the population about this lower

level, whereas we would expect from the trend of the growth of the population

146

up to 1890 that the ultimate density would oscillate about a value of 7115-3

thousands. The maintenance of the population about this theoretical value would,

however, depend upon the stability of the environment, particularly with regard

to the food factor; but the amount of feed available in the pasture areas fluctuates

considerably, owing to the character of the rainfall (2,8). The following features

associated with the development of the sheep industry appear to have played an

important part in keeping the population at the lower level after about 1890.

(a) By 1890 practically all the suitable grazing areas in the State had been

occupied. In certain areas, particularly in the more arid districts, the

sheep had heavily grazed much of the perennial native vegetation, and

regeneration was slow owing to the arid conditions; this reduced the

sheep-carrying capacity of these areas. In the regions having more reliable

rainfall, certain of the earlier grazing areas were gradually taken up

for cultivation with the development of agriculture.

(b) The marked increase in the number of rabbits after about 1870 intro-

duced an additional factor which assisted in reducing the carrying

capacity of the pastures,

selection and “culling,” which grew a heavier fleece, so that fewer sheep

could be carried on the pastures, for an cquivalent weight of wool, com-

pared with the earlier types.

(b) Period 1891-1902

With the exception of a temporary rise in 1899 and 1900 the sheep numbers

show a persistent decline during this period, which continued, notwithstanding

good rains in 1893-4, The whole decade of the 1890’s appears to have been a

period of great economic stress in South Australia (3). The situation was

accentuated by the succession of dry years from 1895 to 1902 which resulted in

the most devastating drought in the history of the State. Agriculture was push-

ing out into the lesser rainfall areas and the difficulties of climate and agricultural

practice were becoming more pronounced.

Under the influence of a succession of good seasons, the population steadily

increased during this period to 6,898,451 in 1908, This approximates closely to

the calculated saturation density, and notwithstanding the continuation of good

rains in 1909 and 1910 the population declined after 1908. It would seem that,

under the conditions of agriculture and pasture management obtaining in the

State up to that time, the country could not permanently support the density of

population which might be expected from the course of the growth curve.

(d) Period 1908-1915

There was a steady fall in the population during this period, which was

accelerated during the dry years leading up to the severe drought of 1914.

147

(e) Period 1915-1936

During the war years, in the early part of this period, the population increased

rapidly to 1919, under the influence of good rainfall in 1916 and 1917 and

sustained prices for wool. The temporary fall in 1920 is associated with the dry

years 1918, 1919. After 1920 the sheep numbers steadily increased to 1927, due

to a succession of years with good rainfall and sustained satisfactory wool prices.

The pronounced fall in the population from 1928 to 1930 is associated with dry

seasons and the drop in wool prices, due to the econcmic depression of this period.

With a return to good seasons after 1930, and the gradual lifting of the depression,

the sheep numbers rose rapidly to a record density of approximately 8 millions

in 1933, which density has been maintained in subsequent years.

The post war period of agricultural development in Australia is noteworthy

for the improvements in pastures and their management. These developments

have raised the sheep-carrying capacity of the pastures in South Australia. It

will be noted that the reduction in sheep numbers during the adverse years of

1928-30 is less pronounced than in the 1890’s and in the years about 1914. This

is due to pasture improvements, particularly by the marked increase in the applica-

tion of artificial manures to natural pastures. The area of top-dressed pastures

increased from 250,000 acres in 1928-9 to 900,000 acres in 1936-7. The areas

under sown grasses in 1921-2 were practically nil; there were 28,000 acres of

lucerne. By 1936-7 there were 250,200 acres of clover, 63,900 acres of sown

grasses and 51,700 acres of lucerne. With the development of mixed farming

methods during recent years, a greater number of sheep is being carried in

association with wheat-growing.

In the arid pastoral regions improvements in water storage and in the manage-

ment of pastoral properties enable the pastoralist to carry his sheep through

drought years more successfully. It should be noted, however, that the increase

in sheep numbers during recent years is particularly due to pasture improvements

in the agricultural areas. The arid portion of the country north of the 10-inch

isohyet carries approximately 21% of the sheep of the State (8).

The first cultural epoch in the pastoral industry, which consisted primarily

in stocking the natural pastures, is being replaced by a second cultural epoch,

the main features of which are illustrated by the pasture developments referred

to above. Under the influence of this new epoch the sheep population is tending

to a new growth curve having a higher upper asymptote. It is not possible to

predict the trend of this curve at present, owing to the incompleteness of the

pasture developments which are in progress.

SUMMARY

The number of sheep present in South Australia, cach year from the founda-

tion of the Province in 1836, is given in the published livestock statistics.

148

These data have been analysed and fitted to the Verhulst-Pearl logistic curve,

illustrating the course of the growth of the population. The formula for the

curve is:

7115-3

249 .106686 — 0.133693x

l+e

The progress of the sheep population during the past 100 years is discussed

with reference to this curve. It illustrates that the saturation density of the sheep

population, which a natural pasture area can permanently carry, is determined

primarily by the feeding value of the pasture, and the regrowth of plants eaten

by the sheep. When the density exceeds this value, the balance is upset and the

carrying capacity of the area will decline. The effect on the area in this respect

will depend upon the degree of overgrazing and the power of the pasture to

recover. In the arid climate of South Australia, the recovery is mainly dependent

on rainfall and may be considerably delayed.

A CENSUS OF THE FREE-LIVING AND PLANT-PARASITIC NEMATODES

RECORDED AS OCCURRING IN AUSTRALIA

By T. Harvey Jounston, M.A., D.Sc., University of Adelaide

[Read 9 June 1938]

The outstanding contributor to the study of Australian free-living and plant-

parasitic nematodes was the late N. A. Cobb, who was for many years associated

with the Department of Agriculture in New South Wales. Most of his work

relating to our subject appeared in the Agricultural Gazette of that State (1890-

1902); the Proceedings of the Linnean Society of New South Wales (1890-

1898) ; and in the Macleay Memorial Volume (1893), published by the latter

Society. Many of Cobb’s articles in the Gazette were re-issued as Miscellaneous

Publications by the Department, as also was his important paper on “Nematodes,

mostly Australian and Fijian” from the Macleay Volume (Misc. Publ. No. 13).

It was in the publications of the Department that Cobb made known his “nematode

formula” (1890, 1893, 1898, 1902), and described his differentiator (1890, 1898)

which has since been used so extensively as part of a technique for staining,

dehydrating and clearing minute and delicate objects, including free nematodes.

His papers included several in the Proceedings of the Linnean Society of New

South Wales dealing with free nematodes, chiefly marine, from Arabia, Ceylon, the

Mediterranean and Western Europe (1890, 1891, 1894). Iis main article on Aus-

tralian marine species appeared in 1898. In some of his accounts of plant-parasitic

forms (Agr, Gaz. N.S.W.; Macleay Volume), information is given regarding

many species which were not then known to occur in Australia.

In the Agricultural Gazette, New South Wales, for 1898 (296-321, 419-454,

figs. 1-127), there appeared his “Extract from M.S. Report on the Parasites of

Stock.” This abundantly illustrated article devotes a great deal of space to free-

living species, but, unfortunately, though well figured, there is usually no indication

of locality regarding them. Many are known to occur elsewhere than in Aus-

tralia and, consequently, in the present census there are included only references

to the figures of stich as are known from information published elsewhere to

belong to Australian free-living or plant-parasitic species. Cobb’s report was re-

published as Miscellaneous Publication No. 215, Department of Agriculture, New

South Wales (62 pp.), under the same title, but the cover bears the legend,

“Nematode Parasites, their Relation to Man and Domesticated Animals.” Two

new figures were interpolated and numbered 40 and 47; consequently there is an

alteration in the numbering of all figures from figure 40 onwards, when compared

with that of the original article. In this census, the original pagination and

numbering of figures are quoted.

In 1917 (1918) Miss Irwin-Smith published an excellent anatomical paper

dealing with some species of Chaetosomatidac from the coast in the vicinity of

Trans. Roy. Soc. S.A., 62 (1), 22 July 1938

Sydney. Allgen (1927) described a number of Tasmanian marine species from

the Derwent River, near Hobart (Brown’s River), from material collected during

the visit of Larsen’s Antarctic (Ross Sea) whaling expedition of 1923-4.

Michaelsen and Hartmeyer, in their collecting trip to south-western Australia in

1905, obtained very few free nematodes, judging from Steiner’s brief account of

them (1916). Most of the remaining references relate to observations by various

workers concerning a few species of great economic importance, ¢.g., some of

those belonging to Tylenchus or Heterodera or allied genera.

Many parasitic nematodes (e.g., Strongylata) have a free-living larval stage,

while certain others, such as Rhabdias and Strongyloides, are heterogamic and

have a free stage represented by males and females. Reference is made to the

few Mermitidae recorded from the Commonwealth, since maturity is attained in

the free-living stage. Though the Gordiacea are regarded as only distantly

related to true nematodes, the few references to the occurrence of representatives

in Australia are included. Plant-parasitic nematodes have received considerable

attention from Goodey in his recent book on the group (1933).

The classification utilized in this paper is based mainly on the recent contribu-

tions of Filipjev (1934) and of Chitwood and Chitwood (1937). The earliest

reference to the presence of free-living nematodes in Australia appears to be that

by Whitclegge (Proc. Roy. Soc. N.S.W., 23, 1889, 307), who in his “List of the

Marine and Freshwater Invertebrate Fauna of Port Jackson and the Neighbour-

hood,” stated that numerous species of Anguillulidae occurred in the local fresh

waters. The earliest records of plant-parasitic species in the Commonwealth seem

to be that of Crawford (1881) relating to car cockle of wheat in South Australia,

and that by Bancroft, whose account of a nematode attacking roots of grape vines

and bananas in Queensland, led Cobb (1890, 166) to state that the figures seemed

to represent Tylenchus arenarius. The latter is a synonym of T. radicicola (of

authors), more correctly known as Heterodera mariont.

Some changes in nomenclature have been made in this paper. Anguillulina

(Fergusobia) temifaciens Currie 1937, pre-occupied by A. tumefaciens (Cobb

1932) Goodey, is renamed A. (F.) curriei; Rhabditis allgeni is proposed for

R. australis Allgen 1932, nec Cobb 1893; Monhystera pactfica for M. australis

Cobb 1893 (1894), nec Cobb 1893; Monhystera gracilior for M. gracillima Man

1921, nec Cobb 1893; M. kreisi for M. gracillima Kreis 1929, nec Cobb 1893, nec

Man 1921; Dorylaimus steinerianus, for D. steineri Thorne and Swanger 1936,

nec Micoletzky 1921; Chromadora cobbiana for C. dubia Cobb 1930, nec Butschhi ;

Epsilonematina for Epsilonema Steiner 1931, nec Steiner 1926 (a renaming of

Rhabdogaster pre-occ.), with type E. steineri (Chitwood 1935) ; Prochactosoma

Baylis and Daubney 1926 is pre-occupied by Prochaetosoma Micoletzky 1921, and

accordingly is replaced by Epsilonema Steiner 1926 nec 1931, and the family name

Prochaetosomatidae is replaced by Epsilonematidae; Drepanonematidae nom nov.

replaces Chaetosomatidae; Chaetosoma haswelli lrwin-Smith and C. falcatiuim

Irwin-Smith are transferred to Tristicochaeta.,

151

RHABDITIDAE

Anguillula aceti (Mueller), the vinegar eel-worm. Peters (1927) proposed

Turbatrix to receive it, but Filipjev (1934) doubted the propriety of the change.

Though apparently unrecorded from the Commonwealth, it occurs in Brisbane,

Sydney, Melbourne and Adelaide, and probably in other parts of Australia.

Rhabditis australis Cobb, Macleay Volume, 1893, 278, from grass, Sydney,

New South Wales. Micoletzky, 1921, 252. In 1932 Aligen described FR. australis

n.sp. (Nyt. Mag., Oslo, B, 70, 1932, 192-4), from Campbell Island; but as the

specific name is pre-occupied, R. allgeni is now proposed for it.

Rhabditis cylindrica Cobb, Agr. Gaz., N.S.W., 9, 1898, 448, fig. 125. No details

are given other than those indicated in Cobb’s formula and figure. No locality

is mentioned, but it is presumably New South Wales. Micoletzky (1921, 258)

stated that Cobb’s species was possibly only a variety of R. strongyloides Schn.

Rhabditis filiformis Bitschli? Cobb, Macleay Vol., 1893, 276-7, pl. 36, from

grass, Sydney; Agr. Gaz., N.S.W., 4, 1893, 832-3, fig. 46, from soil around moss

roots, Clarence River. Micoletzky (1921, 263) included Cobb’s two queried

identifications under R. filiformis, but pointed out that the figure in the former

publication apparently belonged to the species, whilst that in Agr. Gaz., 1893,

fig. 46, is that which Cobb had utilized in the Macleay Volume to illustrate

R. monhystera. Man (Cap. Zool., 1 (1), 1921, 32) stated that Cobb’s species was

probably distinct from, though closely related to, Biitschli’s, because of differences

in the sizes of the eggs and of the genital ducts in the two cases. The Australian

species requires re-examination.

RHABDIASIDAE

Some Australian frogs, especially Hyla aurea in New South Wales and

Victoria, harbour lung worms, Rhabdias sp., which pass through a free-living

generation with distinct males and females.

152

STRONGYLGIDIDAE

Strongyloides stercoralis (Bavay) has been reported from Australian

localities, especially in coastal Queensland, the references having been collected

in a recent paper by Johnston and Cleland (Tr. Roy. Soc. S. Aust., 61, 1937,

276). S. papillosus (Wedl.) has been recorded from sheep, etc., in New South

Wales by Ross and his colleagues, and in Queensland by Roberts. It occurs

also in sheep in South Australia. The free-living generation of these two species

has not received particular attention in the Commonwealth. Heydon and Green

(Med. Jour. Austr., 1931, (1), 626) pointed out the probability of the earlier

published infection rates for humans in North Queensland being inaccurate

because of the common presence of coprophilic Rhabditis spp. in stale faeces.

sheep dung, Moss Vale, N.S.W.; genus stated to be near Cephalobus; no speci-

mens preserved. Micoletzky (1921, 209-10), as well as Baylis and Daubney

(1926), placed the genus in Cylindrolaiminae, Filipjev (1934) regarded it as a

synonym ot Auleolaimus (Diplogasterinae). Chitwood (Jour. Wash. Acad.

Sci., 1933, 512) placed it under Cylindrogasteridae,

CEPTIALOBIDAE

Acrobeles sp., found in garden soil, Reedbeds, Adelaide.

ANGUILLULINIDAE (ANGUINIDAE syn. TYLENCHIDAE)

Anguillulina tritici (Steinb.), more commonly known as Tylenchus tritici,

q.v., also T. scandens. Chitwood (1935) has indicated that Anguina Scopoli has

priority over Anguillulina, but Stiles (Nature, 138, 1936, 34; Zool. Anz., 115,

1936, 110) has suggested that in this case priority should be waived.

Anguillulina dipsact (Kiihn), more commonly known as Tylenchus devas-

tatrix, q.v. Millikan, Jour. Agr. Vict., 33, 1935, 563-6, bulbs, Victoria. Vulipjev

(1934) has assigned the species to Ditylenchus, Syn., Tylenchus dipsaci, q.v.

Anguillulina radicicola Greef, more commonly known as Heterodera radici-

cola or Tylenchus rad., q.v. Goodey (1932; 1933) has indicated that the specific

name should be restricted to the eel-worm known as Tylenchus hordei, whereas

the species generally called T. radicicola should be known as Heterodera marion

q.v.

Anguillulina (Fergusobia) tumifaciens Currie, Pr. Linn. Soc., N.5.W., 72,

1937, 158-163, figs. 26-28, pl. 6-7, from Eucalyptus galls, associated with an

Agromyzid fly, Fergusonia carteri, N.S.W. Type of subgenus. Currie has given

an excellent account of the nematode, which passes through a free-living stage,

with males and females, in leaf galls of Eucalyptus Stuartiana and E, macro-

rhyncha in the vicinity of Canberra. Then there follows a parasitic female

generation in the body cavity of the gall flies. Currie also referred to this

“symbiotic association between flies and nematodes in galls of eucalypt trees” in

Nature, 136, 1935, 263. Unfortunately, the specific name (which should be

amended to tumefaciens) is pre-occupied in the genus by A. tumefaciens (Cobb,

1932) Goodey, 1933, syn. Tylenchus tumefaciens Cobb, from galls in the grass,

Cynodon, in South Africa. Dr. Currie’s attention was drawn to this fact, but he

has requested the author to undertake renaming, if considered necessary. In

recognition of the excellent account of the biology of the species, the latter is

here renamed A. (f*.) curriet.

Anguillulina (Fergusobia) curriei nom. nov. Type of subgenus. See

A, (F.) tumifaciens.

Aphelenchoidées fragariae (Ritzema-Bos), the cause of “cauliflower disease”

of strawberry, “red plant,” or “strawberry bunch” (Cobb, 1891). Cobb, Agr.

Gaz., N.S.W., 2, 1891, 390-400; unnamed nematodes reported as the cause of

the disease in New South Wales, the species being described in the same year by

Ritzema-Bos as Aphelenchus fragariae. Goodey (1933) transferred it to

Aphelenchoides, The disease occurs in South Australia.

Aphelenchus spp. Cobb (Jour. Parasit., 8, 1921, 95) referred to the presence

of twenty-six species of nematodes, including four new (unnamed) species of

Aphelenchus, collected from material about the roots of Kentia palms.

Cobb, Agr. Gaz., N.S.W., 4, 1893, 813, figs. 32-33, as Tylenchus setiferus, from

soil, Clarence River; transferred by him to Entylenchus in 1913 (Jour. Wash.

Acad. Sci., 1913, 437). Micoletzky, 1921, 577. Baylis and Daubney (1926)

regarded the genus as a synonym of Anguillulina, but Micoletzky (1921), Goodey

(1933), Filipjev (1934) and Rauther (1930) considered it valid.

Zuider-Zee (1922-232), stated that a species of the genus had been described

from South Victoria, Australia. He must have confused Cobb’s species, A. polaris

(1914) from Cape Royds, South Victoria Land, collected by Shackleton’s

Antarctic Expedition. The same species was identified by Cobb (1930) from

material obtained by the Australasian Antarctic Expedition from Commonwealth

Bay. Coninck and Stekhoven (1933) transferred the species to Odontophora.

Cobb stated that the genus (which he had just erected) would probably have to

be united with Siphonolaimus. Cobb, Agr. Gaz. N.S.W., 1898, 318, fig. 41 (no

locality given). Steiner (1921), Allgen (1930), Rauther (1930), and Vilipjev

(1934) regarded the genus as a synonym of Siphonolaimus. It may be men-

tioned that Allgen in 1932 and 1933 described new species from Norway and

Sweden, apparently regarding the genus as valid.

Eps1LONEMATIDAE

In 1926 Steiner erected Epsilonema to replace Rhabdogaster Metchnikoff

(pre-occupied), basing its characters on a species which he believed to be the

genotype, A. cygnoides. Baylis and Daubney (1926) had, a few months pre-

viously, proposed Prochaetosoma for it. Steiner (1931) recognised the latter as

valid, gave a diagnosis, and named P. holocricum Steiner, 1931 (an Antarctic

species which was not an original member of the genus) as type. He reported

that the diagnosis given in 1926 was based on a species distinct from Metchni-

koff’s and that, consequently, he retained Epsilonematidae rather than Prochaeto-

somatidae as the family name, In addition to P. cygnoides, he referred to many

new species or varieties fotind in Antarctic and Subantarctic waters by the

“Gauss” Expedition (1931, 312, 316-7, etc.). Ep. cyrtum Steiner, which was not

an original species, was named as type.

161

Steiner (1931) indicated in his key, as also did Cobb (1935), that

Prochaetosoma and Epsilonema Steiner, 1931, were not congeneric because of

differences in the structure of the cttticular annulations. Numerous species or

varieties were described as belonging to the latter genus. Chitwood (Proc. Helm.

Soc., Wash., 2, 1935, 54) designated Lp. stemneri, a new name proposed for

Rhabdégasier cygnoides Steiner nec Metchnikoff, as type of Epsilonema Steiner.

From the foregoing it is obvious that Steiner’s generic name has been applied

to two different groups. In the first place it was a renaming of Rhabdogaster

(Steiner, Jour. Parasit., 14, 1927, 65), as also was Prochaetosoma B. and D.,

the type of this group being XR. cygnoides Metchnikoff. Then, later, the name was

deliberately retained for an allied group, including R. cygnoides Steiner nec

Metchnikoff, renamed Ep. steineri by Chitwood. The second group is admittedly

not congeneric with the former and should be renamed. Epsilonematina is now

proposed for it, with Ep. stemer: (Chitwood) as its type, all the species described

by Steiner in 1931 as belonging to Epsilonema being included under it. As

Prochactosoma B. and D., 1926, is pre-occupied, the name having been used by

Micoletzky (1921, 416), Epsilonema Steiner, 1926, remains as the valid generic

nates for the species included by Steiner (1931) under Prochaetosoma

B. and D.

Epsilonematina spp. Species occur in the littoral zone near Adelaide and

Port Willunga (South Australia) ; Portland and Port Phillip (Victoria) ; Derwent

River (Tasmania); Port Jackson, Broken Bay and Long Reef (New South

Wales).

DREPANONEMATIDAE nom nov,

The new name, Drepanonematidae, is given to the group of nematodes to

which the following terms have been applied :—Chaetosomatiden by Schepotietf

1908 ; Chaetosomidae by Southern 1914, Chaetosomatidae by Steiner 1916, Mico-

letzky 1921, Baylis and Daubney 1926, Allgen 1932, and by later authors generally ;

Chaetosomatinae by Rauther 1930; Draconematidae by Cobb 1929, Steiner 1931,

@) Under Epsilonematina would be included the following species and varieties described

under Epsilonema by Steiner :—Epsilonematina ateles, allohystera, antarctica, aphana, brachy-

craspedota, colobathrophora, cyclophora, cyrta, camptocrica, campta, corynodes, dictyotacrica,

dichotoma, dicrocrica, desmocrica, eucraspedota, frigida, homalocrica, herpeta, homoicrica,

hexastoicha, hetcrocrica, ilyspastica, leptothorax, leptomercs, leptotricha, metchniko fi, mixta,

nana, oligechon, oligoschista, poicilothrit and its varieties strongylota and macra, primitivas

polycrica, philopsychra, pnewmatica, rhogmacrica, rhabdota, simoloma, signatoides, sphalera,

symbiotica, semeionoides, trachelogaster, thinophila, trachelota, thyridocrica and tricola, as.

well as steinert (Chitwood),

Under £psilonema should be included the following species and varieties described by

Steiner under Prochactosoma:—Ep. apionipherum, aschistocricum, atechnum with varieties

heterocrica and lophocrica, cosmetocricum, charactocricum, docidocricum, dynatocricum,

cumecum, eucalobates, eustegum, gcometroides, glaphyrum, glottocricum, hygrum, holocricum,

hadrocteum with varieties asymmetrica and epstlonoides, leptatrachelum, labidurum, monadicum

and varieties conaccphala, microclenum, oligistocricum, oligostequm, placipherum, polyschistum,

penionoides, pachymeriun, EPhenostenaih, striatum, stenocricum, sterrurum, stolidotum, tenue

and fegocricum, as well as cyynoides (Metchnikoff nec Steiner).

162

Allgen 1932, Schuurmans-Stekhoven 1935, and by Chitwood and Chitwood 1937;

and Draconematinae by Filipjev 1934. The correct name is, of course, linked

with that of the type genus, originally Chaetosoma Claparéde, 1863 (pre-

occupied). Tristicochaeta Panceri, 1878, is commonly regarded as a synonym,

and if so, would be the valid name, but Southern (1914) pointed out that they

were distinct. Irwin-Smith (1917) grouped the two under the former name.

In 1913 Cobb erected Draconema. Micoletzky (1921, 416) listed the latter as a

synonym of Chaetosome, considered Notochaetosoma Irwin-Smith as valid, and

proposed Prochaetosoma, with P. primitivum (Steiner) as type, as an additional

genus in the Chaetosomatidae. In 1929 Cobb regarded Draconema as distinct

from Chaetosoma and stated that the latter name should be replaced by Noto-

chaetosoma, which he regarded as synonymous, and that if the family be con-

sidered as containing only one genus, then the name of the latter would be

Draconema, family Draconematidae. In 1933 Cobb proposed Drepanonema to

replace Clapartde’s name, the Zoological Record incorrectly quoting the date as

1922. In 1926 Baylis and Daubney (1926) regarded Tristicochaeta and perhaps

Draconema, as synonymous with Chaelosoma, Rauther in 1930 considered

Draconema a synonym. In 1934 Filipjev erected Claparediella to replace

Chaetosoma, and referred to the differences between Draconema and Noto-

chaetosoma. In 1935 Cobb quoted Draconema as synonymous with Tristicochacta,

and listed Notochaetosoma as valid. Schuurmans-Stekhoven (1935, 100) con-

sidered Filipjev’s name to be the correct one, and placed Chactosoma tristi-

chochacta Panceri under Draconema (p. 101).

From the foregoing discussion it will be seen that the correct name for

Chaetosoma is Drepanonema Cobb, with Claparediella as a synonym, and that the

family should be known as Drepanonematidae nom. nov. (or Drepanonemiatinae,

if only subfamily rank be accorded).

MERMITIDAE

Australian members of this family have not been studied. The adults are

free-living, and the young stages parasitic. Wheeler (Psyche, 40, 1932, 20-32)

referred to Mermis parasitism in some Australian ants. I have seen adults of

Mermis sp. collected from a claypan in the Bordertown district of South Australia.

MISCELLANEOUS REMARKS

Cobb (Agr. Gaz. N.S.W., 1898, 421, fig. 65) illustrated the anterior end of

a nematode, apparently a free-living form, “Labyrinthostoma n, gen.,” but gave

no description, nor did he mention any species or locality. It must be regarded

as anomen nudum. The figure stiggests an Enoplolaimus near E. caput-medusae.

In the same publication Cobb (p. 320, fig. 45) figured Streptogaster

papillatus n. gen., n. sp. without any information regarding habit or locality.

Baylis and Daubney (1926) quoted the habitat as “not mentioned (presumably

free-living)” and placed the genus in an appendix to Rhabditidae. Travassos

(1919) allotted it to Hystrignathinae. Artigas stated that the species was based

on the male of Heth and was, therefore, a synonym of the latter, If this be

correct, Streptogaster must be a parasite of a millipede, and since Cobb in the

same article (1898, 299, fig. 10) figured Heth juli (female) from Julus sp., from

Moss Vale, New South Wales, S. papillatus probably came from that locality and

perhaps from the same host species. Artigas and Travassos (1929) both placed

the genus in Ransomneminae (Atractidae), as also did Filipjev (1934). Cobb

(1935) did not mention the genus in his key to the genera of free-living nematodes.

The species can be placed definitely amongst the parasitic forms.

GORDIACEA

The Nematomorpha may be referred to in this paper, though they are not

true nematodes. Only a few species have been described from Australia. The

group is represented in all Australian States. Though some of the following

references relate to the parasitic stage, they are included, since the worms pass

through a free-living adult phase. No attempt has been made to allocate species

to their proper genera or families.

IT Intrropuction

The interesting occurrence of a large area of augen-gneiss in the neighbour-

hood of the Humbug Serub has been noted by a number of writers, particularly

Brown and Weodward (1885), Howchin (1906 and 1925), Benson (1909) and

Hossfeld (1935). These gneisses constitute an important part of the Older Pre-

Cambrian (Barossian) rocks of the Mount Lofty Ranges in this area.

Howehin (1906, 258) has shown that the adjacent metamorphosed pelitic

sediments pass gradually through a stage of pegmatitic impregnation into the

typical augen-gneiss. He suggests, therefore, that the augen-gneisses have been

derived fram the injection of pegmatite along the cleavage planes of the slaty

sediments. Hossfeld (1935, 24-25), on the other hand, although agreeing with

the field observations of Howchin, “believes that the augen-gneisses may represent

an altered igneous intrusion, changed partly while still in the plastic condition,”

and cites a contact between augen-gnciss and the surrounding injected schists in

Section 3,279, Ilundred of Para Wirra.

Over a large part of the arca in which the augen-gneisses occur the Barossian

rocks are obscured by overlying Tertiary gravels and drift, and the few exposures

consist of rock much altered by weathering. The gorge of the South Para River,

however, gives an excellent section through the northern extremity of the Humbug

Serub region, and the present writcr’s observations are based largely on this

section.

Some years ago the writer, in the course of making chemical analyses of a

number of South Australian rocks, analysed a specimen of a typical augen-gneiss

(S.P.1) from the bed of the South Para River near Section 3,779, Hundred of

Para Wirra. This analysis gave grounds for suspecting that the rock was not

Trans. Roy. Soc. S.A., €2. (1), 22 July 1938

169

of purety igneous origin. The analysis is shown in Table A, column i, where

its composition may be compared with those of typical igneous rocks of this

region.

It will be seen that the augen-gnciss bears no very close chemical resemblance

to any of the analyses quoted. Analyses ii and iii in Table A are typical of the

great majority of granites“) from this part of South Australia. It will be noted

that the K,O and Na,O are approximately equal, One of the rare exceptions

to this is shown by analysis iv, in which K,O exceeds Na,O by 2%. This

analysis has some resemblance to that of the augen-gneiss, but the similarity is not

a close one. Analysis v is representative of the dioritic rocks of Houghton type

which W. N. Benson (1909) and H. N. England (1935) have shown to be of

widespread occurrence in the Mount Lofty Ranges.

Considered alone the chemistry of the South Para augen-gneiss shows no

convincing signs that it may be in part of sedimentary origin, although the

presence of nearly 5% of corundum in the norm and the considerable excess

(34%) of K,O over Na,O may give some slight suggestion of this. However,

the composition of this rock, as will be shown later, is perfectly typical of many

undoubted injection gneisses. It has been shown by the field work of Llowchin

(1906, 258), of Benson (1909, 108), and of Hossfeld (1935, 24), and by the

present writer’s own observations that the augen-gneisses pass outwards through

a region of banded-gneisses and pegmatized schists into pelitic schists which have

undergone a varying amount of pegmatitic injection. The field evidence seems

to support very strongly the idea that the augen-gneisses are the result of a period

of intense injection-metamorphism followed by a period in which the meta-

morphism was of dynamic type. The main object of this paper is to consider

the chemical and mineralogical changes involved in these processes.

Il AUGEN-GNEISSES AND [NJECTION-GNEISSES

The occurrence and limits of the augen-gneisses along the South Para

section have been very well shown by Llossfeld (1935, 23), whose map shows

the South Para River cutting through the northern extremities of the Mumbug

Scrub encisses. The augen-gneisses, which lie within the fringing zones of banded

injection-gneisses and pegmatized schists are of extraordinarily constant com-

position. This constancy of chemical composition is illustrated in Table B. The

three rocks whose analyses are given in columns i, ii and iif in that table were

collected at well-spaced intervals along the South Para section.

A typical hand-spetimen of the augen-gneiss has “augen” of light grey or

pale pink felspar and quariz in a fine dark grey micaceous groundmass. ‘The

quartz may be colourless or slightly blue. The felspar and quartz have obviously

been subjected to extreme granulation. The average size of the prominent felspar-.

quartz augen is about 24 x 3 cm., although a few are much larger than this figure

indicates. Occasionally the augen are so drawn out that the rock consists of light-

() These rocks should more strictly be referred to as adameilites

170

coloured strings of felspar-quartz separated by darker bands of the fine micaceous

material. Such a rock may be referred to as a “banded augen-gneiss.”

Under the microscope the augen are seen to consist of strained quartz and

felspar, generally microcline or microperthite (pl. ix, fig. 5). These are the

dominant minerals of this group of rocks. Acid plagioclase, which usually has

the composition of oligoclase, is generally present but in subordinate amount and

myrmekite is sometimes developed in the potash felspar. The edges of both the

felspar and the quartz are frequently granulated, and these two minerals may

show sutured junctions. This fact, with the varying sericitization of the felspars,

usually more advanced in the plagioclase, gives evidence of the dynamic meta-

morphism to which the rocks have been subjected. The augen are set in a

groundmass of fine sericite in which wisps of biotite and chlorite show very

clearly the foliation direction. Strings of fine granules of sphene are often asso-

171

ciated with this biotite. Occasionally small nests of biotite flakes, most of which

may be transverse to the foliation direction, are apparently the results of retro-

grade changes on some former component. There are no relics to indicate with

certainty the nature of the pre-existing minerals, Iron ore in spongy masses is

common and is frequently associated with sphene and sometimes with biotite.

Accessory minerals which may be present are epidote, muscovite, calcite, orthite

and tourmaline (pl. viii, fig. 3).

of this table the analysis of an augen-gneiss from the island of Bru, near

Stavanger. This rock has been shown by Goldschmidt (1920) to have been

produced by injection-metamorphism, and further reference to it will be made at

a later stage in this paper.

172

In general the central mass of augen-gneiss passes outwards into fringing

zones of banded injection-gneiss and veined schists. Occasionally, however, near

the edge of the true augen-gneiss occur small exposures of a massive rock, of

fine to medium granularity, which does not appear to be of purely igneous

parentage. For convenience the name “‘soda-hybrid” is applied to these rocks.

‘Typical examples occur in the South Para River near the southern corner of

Section 179, Hundred of Barossa (e.g., BA. 21), and near the southern extremity

of Section 183, Hundred of Barossa (e.g., BA.52). In form these small masses

of hybrid rock seem to be in irregular bands or lenses, a few feet in thickness,

which are paralle! to the foliation direction of the augen-gnciss and the surround-

ing gneisses and schists. ‘lhe exact shape of the hybrid masses is, however,

difficult to determine.

Under the microscope a typical soda-hybrid (BA.21) is seen to consist of

porphyroblasts of quartz and microperthite in a finer granoblastic groundmass

of oligoclase, quartz, orthoclase and biotite with a gocd deal of scricite. Spongy

iron ore, apatite and muscovite with small quantitics of epidote and sphene are

also present (pl. ix, fig. 4). The sutured margins of contiguous quartz grains

and the general marginal granulation of the larger minerals mdicate the strong

dynamic-metamorphism to which the rocks have been subjected. A chemical

analysis of this rock is given in Table C. Other examples of this type (e.y.,

BA. 52) have less prominent porphyroblasts but are mineralogically similar to that

described above.

It will be seen from the analysis that silica, alumina and the alkalis comprise

over 90% of the rock, also that soda is in considerable excess over potash. In the

norm these points are reflected in the absolute dominance of alkali felspar over

the other normative minerals. The bulk analysis of the rock cannot be very

different fram that of a soda-rich perthite. The genetic relationship between this

soda-hybrid and the associated augen-gneisses (see Table B) appears, at first

sight, to be obscure.

In a number of places in the section along the South Para River the augen-

gneisses are seen to merge outwards into fine banded-gneiss and thence into schists

(of sedimentary origin) which contain a few bands of felspathic material. The

banded-gneisses appear from their field relations to be directly related both to the

augen-gneisses and to the schists, and this relationship appears to be confirmed

by the texture and mineral composition exhibited by specimens of the rocks

themselves. Mineralogically the banded-gneisses resemble the augen-gneisses,

as fine bands of pinkish quartz-felspar, occasionally swelling into small augen,

are separated by equally fine bands of grey sericitic material. Texturally they

appear to be related to the slightly pegmatized grey sericite schists, the chief

differences being in the greater number and size of the quartz-felspar layers in

the banded-gneisses.

The chemical analysis of a rock which can be taken as typical of the banded-

gneisses (BA. 49) is given in Table D. This is im situ in the bed of the South

Para River, near Scetion 3,279, Hundred of Para Wirra, and fringes a great

“enclave” of schist in the augen-gneiss. With a decrease in the number and size

of the quartz-felspar bands the banded-gnciss merges into the slightly pegmatized

schist. With an increase in the prominence of the quartz-felspar the same rock

passes into typical augen-gneiss.

The average thickness of the light quartz-felspar layers and of the dark

sericitic layers in a typical banded-gneiss is about the same, cach being slightly

more than 1 mm. thick. Under the microscope the felspar is found to be essen-

tially microperihite. Flakes of pale brown to greenish-brown biotite are arranged

in the direction of foliation. Spongy iron ore, much of it showing the change

to leucoxene, is plentiful. Also present are small grains of epidote, an occasional

grain of orthite and a sprinkling of calcite (pl. viii, fig. 2).

If the composition of the banded-gneiss (BA.49) is compared with that of

any of the augen-gneisses given in Table B (columns i, ii and iii), it will be seen

@) Anal. A, R. Alderman

174

that the closest relationship exists between them. It has also been noted that in

its field relationships and texture the banded-gneiss is closely related to slightly

pegmatized schist of sedimentary origin, the main apparent difference between

these two types lying in the greater size and number of the quartz-felspar bands

possessed by the banded-gneiss. It would appear, therefore, that these two rock

types, the banded-gneiss and the schist, were originally similar and that they now

differ only in the degree in which they have been pegmatized.

The banded-gneisses thus seem to provide a most interesting link between the

augen-gneisses and the sedimentary schists, and in order to investigate this

suggestion the composition of the latter rock types will now be discussed.

Tl] THe Scuists

The broad field relations between the main body of augen-gneiss and the

surrounding schists in the South Para section have been excellently shown by

Hossfeld (1935, 23). The more intimate relations between these two rock types

have already been mentioned in this paper,

The schists which are to be seen in the section seem to be of very uniform

type and composition. In some localities, ¢.g., the southern corner of Section 180,

Hundred of Barossa, definite bands of extreme granulitization may be recognised.

The trend of these granulitic bands is north-south, this being in conformity with

the direction of foliation of both the schists and the augen-gneisses. On the

whole, however, the schists which are adjacent to the augen-gncisses exhibit a

great uniformity of texture and appearance. They are, for the most part, fine-

grained grey rocks in which very fine bands of light-coloured quartz and felspar

are often to be seen parallel to the foliation (pl. viii, fig. 1). These rocks are also

intersected by comparatively coarse veins of pegmatite or of quartz, the veins

measuring up to an inch or so in thickness. These coarser veins may cut across

the direction of foliation and seem to belong to a later stage in the rock’s meta-

morphic history.

Analyses are given in Table E of two rocks which may be taken as typical

of the grey schists. Of these, BA.23 occurs in the gorge of the South Para

River a few yards from the augen-gneiss near the north-east corner of Section 289,

Hundred of Para Wirra. S.P.3, which was collected and incompletely analysed

a few years ago, occurs in a similar situation but near Section 3,279, Hundred of

Para Wirra. Under the microscope these rocks are seen to consist largely of

fine sericitic mica containing small flakes of biotite. The direction of foliation

is strongly marked in these micaceous minerals, and is also well shown by the

plentiful micro-augen of quartz and of microperthite. In this same direction the

rock is sometimes strongly granulitized in narrow bands. Of the same general

size and shape as the micro-augen of quartz and microperthite there may be seen

lenticular aggregates of fine chloritized biotite with fine flakes of muscovite,

powdery iron ore and some exceedingly fine needles which may be rutile. In

these aggregates the mica flakes do not follow the direction of foliation of the

175

rock, and the aggregates themselves seem to represent some former mineral on

which retrograde changes have acted. The usual accessory minerals in these

rocks are iron ore, tourmaline, apatite, epidote and occasional grains of rutile.

The analyses stated in Table E indicate several points of interest. Firstly,

that the grey schists have a very constant composition, The analyses in columns i

and ii are of rocks occurring approximately a mile apart. Secondly, a comparison

of columns i and ii with columns iii and iv indicates that the South Para schists

have a composition which is quite usual for rocks of that type. Thirdly, a com-

parison of the norm in column i with the norms of any of the augen-gneisses

shown in Table B, shows that the only important points of difference in the

normative compositions of these two very different rock types lie in the greater

amount of corundum and smaller amount of albite in the schist. It will be seen

that if more soda and silica were to be added to the schist, thus converting its

corundum into albite, a rock very similar in composition to the augen-gneiss would

be produced.

TV PEGMATIZATION OF THE SCHISTS

The above description of the Humbug Scrub augen-gneisses and of their

field relations is believed to indicate the following points:

(i) The chemical and mineralogical composition of the augen-gneisses suggests

that these rocks are not of entirely igneous origin. Further, they differ

materially from the known igncons rocks of the region (Table A) and

resemble rocks whose origin is recognised as being due to injection-

metamorphism (Table B).

(ii) The augen-gneisses merge outwards into banded-gneisses, which in turn

pass, with decreasing pegmatization, into grey schists. The banded-gneiss

has been shown to be chemically identical with the true augen-gneiss

(Table D).

(iii) If banded-gneiss is formed by pegmatitic injection of the grey schists it

would then appear that the augen-gneisses owe their origin to the same

process.

lf an examination of these rocks was based on field evidences alone the

injection-metamorphism would appear to be a comparatively simple process cou-

sisting of the lit-par-lit injection into the schists of quartz-felspar pegmatite.

The textural properties of the augen-gneisses and their associates would have

developed in a subsequent period of dynamic metamorphism.

A comparison of the chemical composition of the schists with that of the

banded- and augen-gneisses shows, however, that the injecting material cannot

have been quartz-felspar pegmatite. On the other hand, it will be seen that by

adding to the schist a mixture consisting largely of sodium silicate the product may

have a composition identical with that of average augen-gnciss, if some water is lost

in the process. ‘lable F shows the effect of adding to an average South Para schist

(column i, average of two analyses in Table E) a mixture of 35°7 parts of silica,

2-7 parts of soda, 1-3 parts of potash and 0°8 parts of lime. Water in the propor-

tion of 1°2 parts is subtracted (column ii). Column iit gives the resulting mixture

and column iv the composition of average augen-gneiss taken from the threc

analyses in ‘Table B.

It will be seen that an adequate explanation of the chemistry of the injection-

metamorphism can be offered if it is assumed that the added material consisted

of alkali-lime-silicate. It is interesting to compare this explanation with that of

Goldschmidt (1920), who showed that the augen-gncisses of the Stavanger region

were probably produced from phyllites by the addition of a mixture consisting

of SiO, 34 parts, CaO 2 parts, Na,O 3:3 parts, K,O 2:3 parts, and the loss of

2°6 parts of H,O.™> Goldschmidt’s conclusions were based on a very complete

series of analyses. The same writer has also shown in a later paper (1922) that

if the concentration of such alkali-silicate solutions—‘a kind of water-glass”—

is greater than a cerlain minimum they constitute highly potent metasomatic

agents.

The close correspondence between the apparent mctasomatic reactions in the

South Para and the Stavanger regions is very notable. ‘here is also a striking

similarity between the calculated compositions of the incoming alkali silicates in

both localities. Another locality where a similar action may have taken place is

Cromar, Deeside, Aberdeenshire, where, it has been suggested by Read (1927),

oligoclase-porphyroblast-schists may owe their origin to a similar type of injection-

metamorphism,

The injection-metamorphism in the South Para region may thus be pictured

as a lit-par-lit injection into the sericite schists of alkali-silicate solutions. This

would be accompanied by a certain amount of permeation from the main narrow

channels of injection and a metasomatic change of the sericitic mica, alkali-

felspar being the main product of this metasomatism. The chemistry of this

change may be simply reptesented by the following equation:

(OH), Al, [Al Si,O,,]K 4+ Na,SiO, + 5SiO,

sericite “water-glass” solution

K[AI S1,0,]

= 2Na/ Al Si,O.] + I1,0

alkali-felspar water

(microperthite)

The type of metasomatism displayed by such a reaction is that in which

excess alumina—im this case in the sericite—is bound by the incoming alkalis.

Goldschmidt (1922, 120) has shown that in such metasomatic processes a

minimum concentration of the alkali silicate is necessary, at a given temperature

and pressure, to cause the separation of felspar at the expense of mica. If this

minimum concentration of alkali silicate does not exist, the circulating solution

can only leach the mica, but not deposit any felspar.

Jt is thus evident that where the alkali solution is of low concentration it will

gradually become saturated with alumina, and with falling temperature will

eventually solidify as a rock or pegmatite largely composed of felspar. In

Table G the calculated composition of such a felspar rock is given. ‘This is

obtained from the calculated composition of the “water-glass” solution by adding

enough alumina to saturate the alkalis and lime.

It will be seen that the calculated chemical composition of the felspar rock

—formed by the solution of alumina in “water-glass”—has a surprisingly close

correspondence with that of the soda-hybrid (BA. 21) previously described

(Table C). The addition of about 7% of iron, magnesium and water to the

felspar rock would make the two compositions almost identical. This comparison

thus seems to provide an adequate explanation of the genesis of the soda-hybrids,

as well as a confirmation of the activity of the water-glass solutions.

Vo Meramorpuic History AND CORRELATION

In a review of the processes of injection-metamorphism Read (1931, 146-

150) concludes that the conditions necessary for such injection are ‘‘activity of

stress and prevalence of high temperatures in the country-rock of the complex.”

In mountain-building movements accompanied by intrusion of magma these condi-

tions are provided immediately after a tectonic maximum, In the Loch Choire

complex in Sutherland Read has shown that the metamorphic grade of the

injected rocks is raised, and sillimanite occurs only within the injection complex.

In the South Para section sillimanite and other high-grade minerals have

not been detected. This may be due to one or both of two factors: (1) The

South Para gneisses having apparently been produced from a process of injection

combined with permeation, the formation of sillimanite and allied minerals may

have been prevented by the presence of alkali-silicate solutions; or if such

minerals had already developed in the schists, these solutions may have converted

them back to mica. Read (1927, 333) has described the change of sillimanite,

andalusite, garnet and staurolite to micaceous “shimmer-aggregates” in the injec-

tion complex of Cromar, and suggests that these changes are due to the passage

through the rock of alkali-silicate solutions; (2) minerals of high metamorphic

grade may have been changed by retrogression during the subsequent stage of

dynamic metamorphism. In such a change mica would again be the main product

of the retrograde processes.

179

Occasionally some rounded inclusions and other enclaves of schist occur in

the augen-gneiss. These seem to be blocks of country rock which have resisted

or been protected from injection. They may resemble the rounded inclusions of

eclogite which occur in the injection-gneisses of Inverness-shire (Alderman, 1936,

527) and thus be residual kernels of the country-rock which have escaped injec-

tion. It would appear that the contact between augen-gneiss and schist mentioned

by Hossfeld (1935, 25) is of this nature, the country-rock forming a promontory

or large enclave which has not been injected.

The source of the alkali-silicate solutions is as yet indefinite. At Stavanger

the source has been convincingly traced to an igneous intrusion of trondhjemitic

composition. At Loch Choire and at Cromar the parent igneous rock is not

obvious, but it would appear that one of trondhjemitic composition is again the

most likely. In the Barossa district intrusive igneous rock may be hidden in the

Humbug Scrub region to the south of the South Para River, but information

and evidences on this point are very vague. Hossfeld (1935, 52) mentions the

possibility of the pegmatization of the Barossian schists being contemporaneous

with the intrusicn of the igneous rocks at Houghton and Mount Kitchener. The

diorite described by England (1935) from Section 257, Hundred of Barossa,

would also be included in this possibility. The other large igneous masses of this

region, the Tanunda Creek and Palmer adamellites, seem to be of later date than

the period of injection-metamorphism,

Following or perhaps partly contemporaneous with the injection-period the

augen-gneisses, and the other rocks of the South Para section, were subjected to

strong dynamic metamorphism, This may have immediately followed on the

injection stage and produced the final effects of the single tectonic period. With

falling temperatures the kind of metamorphism would change from an injection

type to conditions in which shearing stress was dominant. The presence of

granulitized bands with a north-south trend in the schists, and particularly in the

region to the south and west of the South Para section, seems to indicate strong

thrusting movements from the west (pl. ix, fig. 6). These were evidently of

later date than the injection period.

That the rocks within the injection complex must have been subjected to

strong internal stresses produced by the injection is evident from a consideration

of the mineralogical changes. It will be seen from Table F that about 100 parts

by weight of schist react with about 40 parts of “water-glass” to produce augen-

gneiss. However, it will be seen from the following equation that, theoretically,

scricite and water-glass can react in approximately equal amounts to form felspars.

Molecular weights are given beneath the empirical formulae.

From these considerations it would appear that about % of the schist was

effected by the metasomatic change. The increase, produced by this meta-

somatism in the volume of the rock is shown by comparing the volumes of the

constituent minerals before and after the reaction. The sizes of the molecules

of muscovite, orthoclase and albite are given by the volumes of each mineral in

cubic Angstrom units per oxygen atom. These figures are for muscovite,

19-2, orthoclase 23, albite 21-6. The volume change of the solid constituents is,

therefore:

muscov.te orthaclase + albite

192x122 — 23x8 2x21:6x8

230°4 529°6

This shows that at normal temperatures and pressures about two-fifths of

the rock would increase to about two and a quarter times its original volume as

a result of the metasomatism. The whole rock would, therefore, nearly double

its volume.

Although these calculations cannet give an exact idea of the volume changes

produced under natural conditions and under high temperatures and pressures,

they at least indicate that the metasomatism will cause a great increase in the

volume of the rocks concerned. ‘This volume change would, undoubtedly, set up

great internal stresses in the augen-gneisses and may thus account for much of

the retrogressive change and granulation exhibited by these rocks,

VI SuMMARY

The Humbug Scrub augen-gneisses, which are an important feature of the

Rarossian (Pre-Cambrian) series in South Australia, are w ell shown in the gorge

ot the South Para River. They appear to have been developed during a period

of injection-metamorphism in which alkali-silicate solutions reacted wil the

seticite-schists of the complex. This process normally produced augen- gneisses

and banded-gneisses, but when the concentration of the metasomatic solutions fell

below a certain level hybrid rocks rich in soda were formed. One of the results

of the injection and metasomatism would be a large increase in volume, to which

may be ascribed many of the effects apparently due to subsequent dynamic-

matomorphism.

Summary

In view of the relative poverty of our knowledge concerning the ecology and distribution of the

herpetofauna of the central area of the continent, it seems advisable to publish the following notes

based on part of the collection gathered by Mr. H. H. Finlayson during some of the journeys which

he made through that region in 1933-1935.

In view of the relative poverty of our knowledge concerning the ecology

and distribution of the herpetofauna of tie central area of the continent, it seems

advisable to publish the following notes based on part of the collection gathered

by Mr. Il. I. Finlayson during some of the journeys which he made through

that region in 1933-1935.

Most of the material comes from Officer Creek, which lies midway between

the Everard and Musgrave Ranges in the far north-west of South Australia;

others [rom Palm Creck in the Mucdonnel Range. The homogeneity of the fauna

throughout “his area is emphasised by noving that of the twenty-two spectes taken,

no fewer than thirteen were also collected at [Icrmannsburg on the Finke River,

Northern Territory, in 1931, by Mr. W. E. Schevill on behalf of the Museum

of Comparative Zoology.

In the following notes the letters H.H.F. denote that the specimen is still in

the Finlayson collection, while M.C.Z. precedes the catalogue number of those

presented to this Museum. Scale counts, or other pertinent matter likely to be

of use to future investigalors, are given as a check on my determinations. Anno-

tations as to the aboriginal name, colour in life, ete., made by the collector are

included, together with some observations on breeding and dict. Attention is

particularly directed io the voraciousness displayed by the gecko, Nephrurus lacvis,

as well as the discovery of the adult skink, Egernia imornata.

except for the anterior four; labials 6, the third and fourth entering the orbit.

‘Total length 200 (178 + 22) mm.

The top of the head presents a very different appearance from that of the

example figured by Kinghorn (1929, p. 155), it is wholly black except for a light

area in the centre of each of the scales anterior to the frontal and eye. There

are 24+ 5 annular rings on body and tail, “the interspaces are orange in life.”

In her stomach is a young gecko (hyuchocdura ornata), a large scorpion,

and many parasitic nematodes (Psysaloptera sp.).0? The smaller $ has an

apparently regenerating tail of a more granular and less spinose appearance.

flat white tubercles like those on the back, but each forming the centre of a circle

of black granules. Larger gecko measures 68 (42 + 26) mm.

Keels of the upper dorsal series obliquely directed towards the vertebral line;

nostril a little nearer the orbit than to the tip of the snout; tail roundish. ‘This

identification is made with the same reservation as regards the raidity of

quatinorfasciatus Sternfeld as T (1934, p. 329) have already made. No lower

hight streak on the flank is discernible. Mr. Finlayson, however, states than ‘“‘an

area of blue is present on the sides during life, though it is now absent.” Te

adds that the species is very conimon over most of Central Australia, is readily

tamable, and is a good fly-catcher,

This individual agrees with our long series of gouldii as defined (1934, p. 332),

except that it is immaculate bencath, apart from some obsolescent dusky streaks

on the throat. In this respect alone it would appear to conform to giganteus

Native Names: Moatinga for the spotted or striata type; fuleeri for the

uniform or inornala type; tcharcoora for the handsome adults.

For reasons stated below, the scale counts, ete, of the two feharcoora are

discussed independently of the series from Officer Creek, which are:

Midbody scale-rows 36-44; length from snout to anus, alter elimination of

those with regenerated tails, is included sn length of tail from 1:01 in the largest

to 1:2 in the smallest. ‘Uhese two skinkg measured 95 (43 + 52) and 208 (103 +

105) mm., respectively.

The teharcoora (M.C.Z. 43749) is the specimen which formed the subject of

the photograph facing page 62 of Mr. Finlayson’s book, “The Red Centre.” In

life its dorsam was a rich shining cupreus red, the flanks were banded alternately

with red and yellow (possibly also with bluish-green, according to Mr. Finlayson’s

recollection); the undersurface was a very clear, bright Iemon-ycllow. These

colours have faded in the alcoholic-preserved reptile, but are present to some

extent in the salt-prepared skin from Toonunnya water; this is particularly the

case with the belly, which has retained its bright Icmon-yellow hue.

The midbody scale-rows are 46 or 48 in these two big skinks, whereas the

range shown by the twenty-four examples from ITermannsburg and Teatree Well

(Loveridge, 1934, p. 337) was only 38-46, those from Teatree averaging higher

than the more westerly :lermannsburg series. As none of these skinks exceeded

228 mm. in length, I dissected several but without finding signs of enlarged

gonads in any, so that I was Iead to the conclusion that both they and the Officer

Creek series listed above are immature individuals. On dissecting the 376 mm.

Pundi tcharcoora, however, she was found to be a gravid female bearing four

embryos when killed on 8 January, 1934. These embryos varied a good deal in

tail length, onc, a @, measured 78 (43 + 35) mm. and had 46 midbody scale-rows.

It is interesting to compare its length with that of an active juvenile from Ofhcer

Creek as given above. ‘The length from snout to anus of mother and embryo is

included in the length of tail 1:005 and -81 times, respectively.

Mr. }Inlayson, not unnaturally, concluded that the feharcoora represented

a distinct species, but in the absence of any scale characters which serve to separate

188

them, and for the reasons stated above, I conclude that he has secured the first

adults of imornata, a species with a midbody scale formula of 36-48; whether

striata may eventually be recognised as a race remains to be seen.

Coming, as they do, from the far north-west of South Australia, these skinks

assist in bridging the gap between the nominate form and the race which is

common in central and north-west Australia.

Midbody scale-rows 40; supraoculars 2; supraciliaries 5; frontonasal

separated from frontal. Bands on body 4, on tail 3. Larger skink measures

405 (275 + 130) min.

Native name, Culameer, ie., differing from that in use at Anningie.

Midbody scale-rows 40; auricular lobules 4; frontonasal separated from

frontal. Transverse bands on body 12, on tail 10; in life these “were orange,

the intermediate areas olive green” (H.H.F.). My colleague, Dr. P. J. Darling-

ton, could only detect the remains of ants, though of several species, among the

masticated mass which distended the stomach and enormous intestinal tract.

1 (M.C.Z. 43127), Officer Creek, S.A., Jan., 1934,

Midbody scale-rows 26; supraoculars 3; digits 5; toes 5; agreeing in all

respects with our topotypical material (vide Loveridge, 1934, p. 366). Total length

175 (95 + 80) mm.

1&9

While the finding of this skink in South Australia removes my doubts as to

muilleri and petersi being syonymous, the status of miillert is unaffected by its

transfer to the genus Vuliqua, for the name remains preoccupied in Lygosoma.

This species, the length of whose hind limb equals the distance between the

centre of the eye and the fore limb, differs in this respect from the definition of

Section I (Sphenomorphus, inc. Hinuli«) of Lygosoma as given by Boulenger

(1887, p. 212). In 1934 I followed ‘Sternfeld in referring it to Omolepida.

Recently Malcolm Smith (1937, p, 233), in studying the status of many skinks

formerly included in the genus Lygosoma, found that in dentition, as well as in

having the parietals completely separated by the interparictal, casuarimae agrees

with Tiligua. We also transfers to that genus branchiale, gastrostigma and

woodjonesi. While the two c. casuarinae and three topotypical c. petersi have

the parietals completely separated, in the Officer Creek specimen they are just in

contact behind the intcrparietal.

It might be as well to invite attenlion here to the fact that Dr. Malcolm

Smith (1935, p. 279) has also shown that certain oriental species so bridge the

alleged gap between Lygosoma (sensu strict) and Sphenomorphus that it is

impossible to retain the latter as a distinct genus, and considers that it should be

treated only as a section. If this vicw is accepted, then the Australian species

referred to Sphenomorphus and Leiolopisma must revert to the older name of

Lygosoma, which will involve some radical changes in their nomenclature.

The largest measures 43 mm., a juvenile only 26 mm. Two of the adults

were in embrace, the pale yellow male superimposed on the duller brown female.

All exhibit the more extensive webbing of the toes characterising a new species

being described by Mr. H. W. Parker (in press) as distinct from ornatus. Shere

is, however, remarkable divergence in the extent of webbing as between the frogs

from Ernabella and Palm Creeks, not more so, however, than is to be observed

in a series from [lermannsburg or than has been figured by Spencer under the

name of ornatis.

Tt might be remarked here that the Mermannsburg material (M.C.Z. 18530-

46) which, following Spencer, I erroneously referred to ornatus, and of which

examples were sent to most Australian museums under that name, was sub-

sequently studied by Parker, who has designated them paratypes of his recently-

described species.

This young frog, only 24 mm. in length, undoubtedly represents gilleni,

which I (1935, p. 39) tentatively referred to the synonymy of caerulea, Unfor-

tunately the shrivelled condition of this specimen makes it impossible to reach a

decision as-to whether my action was justifiable. It does exhibit a light ante-

brachial patch, and apparently the whole upper lip as far as the tympanum was

pale blue in life.

I juvenile (M.C.Z. 22380), South’s Range, N.T., 20 Jan., 1935.

The largest of these three young frogs is only 19 mm. in length, but they are

obviously specifically identical with our Lake Barrine, Queensland series (M.C.Z.

18051-2). The dorsum of the young is greyish while the limbs and lateral line

on the flanks are finely punctate, thus presenting a somewhat different appear-

ance from that of the adults. Spencer (1896, p. 170) has already recorded this

species from Palm Creek and other localities in Central Australia.

Of this and the two preceding species Mr. Finlayson writes: “T took these

frogs in midsummer during heavy rain; an hour after the storm commenced the

rocks were swarming with them. The dark ones were rich green; the others red-

brown, I think.”

Ll INTRODUCTION

This is the third of a scrics of papers dealing with investigations into the

characters and origin of the peculiar glassy objects called australites, found widely

and almost universally distributed over the greater part of the southern two-thirds

of the Australian continent, including Tasmania and adjoining islands.

Part J of the serics (103) dealt with the classification of the Shaw collection,

a representative series of forms numbering 3,920 pieces. Part IL (112) con-

sisted of an enquiry into the numbers, forms and distribution of australites, with

some speculations as to origin.

In this paper additional facts concerning the forms and distribution of

australites are set down, and evidence is presented concerning the probable

sequence of development of the “round” forms of australites, together with

speculations concerning probable methods of cosmic origin.

During 1937 the writer was privileged to examine the chief tektite collec-

tions of the world, and to discuss the associated problem with authorities on such

matiers in Europe, North America, and South Africa. Further, by the courtesy

of Professors von Koenigswald and H. O. Beyer, a considerable amount of new

tektite material from Java and Philippine Islands was placed at his disposal.

Professors 1. A. Cotton and H. C. Richards generously lent their complete

collections of Darwin Glass. With this and other material the writer is at present

engaged upon a comparative study of the internal and external structures of

tektites.

Warmest thanks are due to Mr. W. Baragwanath, Director of the Geo-

logical Survey of Victoria, for his continued assistance. Tor the photographic

work acknowledgment is made to the Director of Lands, Mr. E. J. Field, and to

Mr. M. FE. Sherrah; and for the microscopic photographs of smoke bombs to Mr.

R. A. L. Laughton, of the S.A. School of Mines. The kindly assistance and

encouragement of Dr. L. J. Spencer is deeply appreciated.

The australite problem can be adequately considered only when viewed as

a part of the greater tektite problem. To assist Australian workers in this’

direction the attached bibliography has been compiled, and it is, for the most part,

limited to those papers that are likely to be accessible to and necessary for Aus-

tralian workers. These references are set out in chronological order, indicating

to some extent the development of scientific opinion upon the question.

II THE PRESENT STATUS OF THE TEKTITE PROBLEM

While there may be some truth in the statement that the geologist, petrologist,

and mineralogist have done all that they can towards the solution of the tektite

problem, and that the work of the physicist, mathematician, and astronomer are

now required, it scems likely that the majority of workers in this field will con-

tinue to be geologists and mineralogists.

Nevertheless, as instanced by the work of Kerr Grant (41), ‘Tilley (72),

and La Paz (122), the contributions from the physical and mathematical points

of view are decisive and important. ‘he next significant move probably les with

these methods of study.

The unfolding of the tektite story has taken place over 150 years, slowly at

first, but with accelerated pace during the present century. Bits of green glass

found in Moravia were analyzed by Dufrenoy (1) in 1787. German and French

travellers, in the early 1800’s, referred to various glass balls occurring in nature,

but these were possibly of volcanic origin.

Moldavites thus appeared in the picture in 1787, 151 years ago. Australites,

not under that name, first came into literature with Darwin’s reference and figure

in 1844 (2), 57 ycars later, Billitonites were first described by Van Dijk (8)

in 1878, another 34 years onward, quoted by Beyer (109). Thus, in the first

century of this account, there had been no more than three simple descriptions,

with no suggestion of correlation, and no important efforts to discuss the question

of origin.

Meantime, in Australian geological and mineralogical literature, there had

been numerous records of specimens and localities, usually with an acknowledg-

ment of the mystery of their origin and distribution. At the same time a con-

siderable literature grew up around the moldavites. mostly in the German and

Czech languages. Makowsky (quoted by Beyer, 109), conrpared billitonites and

moldavites in 1881, and in 1893 Wichmann discussed and compared moldavites,

billitonites, and australites.

By the year 1900, despite the bias given towards volcanic theories by Darwin

and others, there had grown up a conviction that an extra-terrestrial origin was

indicated. The number and ingenuity of the suggestions put forward then and

since are well known. Throughout the story the remarkable shapes and distribu-

tion of the australites have exerted a special influence upon the investigations.

It seems likely that Streich (18) was the first to advance a meteoritic theory of

origin; that was in 1893, in a private letter to Professor A. W. Stelzner, of Frei-

berg (ref. 18, p. 112).

In 1898, Suess (27) clinched the idca of cosmic origin, and grouped all the

known series together as “tektites”. This theory has been generally accepted on

the Continent, in south-eastern Asia, and in Australia. Although no accepted

tektite groups have been reported from the Americas, there are at least six

localities in those continents from which claims have been put forward for the

existence of tektites.“

Since 1900 the outstanding suggestions, from the Australian point of view,

have been Dunn’s bubble hypothesis, which has proved to be quite unacceptable,

the “burning light-metal meteorite” hypothesis, and T.. J. Spencer’s theory of

meteoritic impact. While the latter cannot be accepted for the australites, nor for

any of the major groups of tektites, it has given a powerful stimulus to discussion

upon these matters, and is favoured by some workers as the explanation of the

less widely distributed silica glasses.

In a recent paper (122) La Paz discusses the Great Circle theory of dis-

tribution of the tektites, from the point of view of the probability of their

occurrence along such great circles under the varying conditions attached to

voleanic, fulguritic, meteoritic, and other theories. His investigations deal

primarily with the David—de Boer Great Circle (77, 80). Since The Ivory Coast

Tektites of Lacroix (106) and the Jibyan Silica Glass of Spencer (104) both

@) A curious statement is made as a foutnote to la Baz's paper (122), to the effect

that “Tektites are exhibited occasionally in placer mining camps in the United States.

However, it is the author’s experience that persistent questioning discloses always that

such specimens come originally from the tektite-sprinkled goldfields of Australia.’ There

may be some association between this fact and the Australian goldficld superstition that

where tektites abounded the gold was richer.

lie outside that Circle, he postulates a second, the Lacroix-Spencer Great Circle,

and suggests that further discoveries of the alignment of tektite areas and

meteorite craters might thereon be anticipated.

‘Yhe theory of a burning light-metai meteorite, shedding blobs of contained

siliceous material, was put forward and elaborated by Lacroix (88), and

Suess (87), having been developed from the somewhat different cosmic theories

of Goldschmidt (74) and Michel (75). This hypothesis overcomes many

difficulties of age, composition, distribution, and form that were not reconcilable

with terrestrial theories, and may be regarded as being at present the most

acceptable that has been put forward. Hardcastle (76) produced a very interest-

ing theory on somewhat similar lines.

Eyen with the acceptance of a cosmic theory of origin there still remains

considerable doubt as to the precise manner in which the tcktites were brought

to the earth, were melted, and were distributed. Most of the references published

since 1900, 94 of which are given in the attached bibliography, are cither descrip-

tive of the properties and distribution of different groups, or are efforts to more

clearly define an acceptable cosmic theory for the tektites as a whole.

Hl ADDITIONAL FACTS CONCERNING THE DISTRIBUTION

OF AUSTRALITES

In a previous paper (103, pp. 127-8) cxampies were given to show how

widely and generally australites were distributed, On the accepted figures, there

must have been at least one to every two square miles, and while in some areas

they are mach more abundant (vide Dodwell’s collection of 250 pieces on one

square mile), it seems possible that there are few regions within the known strewn-

field where australites did not fall.

Two interesting examples should be added to those already quoted, one

reported from a locality near Port Campbell, Victoria, and the other from near

Moonta, South Australia. Neither of these places, so far as { know, had hitherto

been recorded as australite localities.

In 1936 George Baker published a paper (115) telling how he had collected,

near Port Campbell, a representative series of 83 tektites, spread over an area of

three square miles, mostly resting on the surface. Like most specimens found

by “collectors,” as coutrasted with those found by gold-miners or tin-miners, the

pieces were relatively fresh and unweathered in appearance. Later, Mr. Baker

found 52 additional specimens on the same area, [A further account by Mr.

Baker states that he has since increased his finds to 250 specimens, all of them

to the east of Port Campbell, and none to the west, vide “Walkabout,” July,

1938, p. 36.|

‘The Moonta area in South Australia was equally unsuspected for the

presence of australites until Mr. J. KE. johnson commenced to take an interest in

these objects. Le commenced his search among the Moonta sand-dunes, adjoin-

ing the coast of Spencer Gulf. Tle found one in July, 1937. Since then, in less

196

than a year, he has found 72 pieces. It should be mentioned that these dunes were

the sites of aboriginal camps. Australites are known to have been used by these

people, both for magic purposes, and as material for cutting-tools. Mr. Johnson

is of the opinion that many of the specimens collected had not been carried by

the blacks. Most of the picces were found exposed after wind storms, and the

whole arca where they were collected was but a few acres in extent.

These two instances support the examples already published as evidence of

the general distribution of australites throughout southern Australia, as indicated

in the map of distribution (114) ; but they emphasise the fact that some localities

are rich in specimens and others very poor.

IV NOTES ON SMOKE BOMBS FROM LOCOMOTIVE ENGINES

In a previous paper (103, p. 72) the writer has referred to the valuable

information to be garnered from a study of the smoke bombs (also called slag

bombs) ejected from the chimneys of locomotive engines.

By the courtesy of Mr. E. H. Shapter, of the South Australian Railways,

the writer has been enabled to study this material further. Samples were obtained

of the cinders deposited, (a) on the rear of the tender of a locomotive of the RX

type, (5) on the front of the tender of a mountain type engine, 47 feet from the

chimney, (c) on the rear of the tender of a mountain type engine, 73 feet from

the chimney.

There proved to be no outstanding differences in the samples. In each case

about 99 per cent. of the material collected consists of cellular coke fragments,

etc., and about one per cent. (by bulk) of the beautifully-shaped and many-

coloured tiny glassy blobs that show regular forms. Sample (b) naturally con-

tained more large specimens than sample (c), but the richest in these bead-like

forms was that from the RX engine, sample (a).

The separation of the material is easily carried out, first by running water

which takes off the lighter coke fragments, and then by a cautious “panning off”

process similar to that of the alluvial (placer) gold-miner. The photographs

shown in pl. x illustrate a sample obtained in this way, as well as scleeted

specimens of the oval, dumbbell, and teardrop types.

As the photographs show, the dominant forms are very beautiful and almost

perfect spheres, perhaps cighty per cent. of the total. These are of various

colours: dead black, china white, amber, green, vellow, etc. Some of them are

tubercled, by the attachment of smaller spheres, and many of them contain gas

bubbles, both spherical and drawn out. Ovals and flat discs are fairly common,

and the dumbbells and teardrops least common; the more fragile teardrops and

dumbbells are casily broken by rough treatment of the sample.

The microscopic examination of smoke bombs is a matter of exceptional

fascination. Despite the limitations of form and colour, already mentioned, there

is remarkable variety and beauty to be found. The forms vary considerably in

size. The largest I have seen, a veritable “giant,” almost a hand specimen among

197

these tiny forms, was a flattened spheroid, the greater diameter of which was one

millimetre. Below this there are forms of all sizes, and as one increases the

magnification, particularly by micro-photography, smaller and smaller forms

appear, quite perfect in shape, among the particles of fine dust that accompany

the material.

Similar forms to these smoke bombs have been recorded from volcanic

sources, as well as from the sites of meteoritic impact. Moore (65) records some

among Pele’s tears from Hawaii, while Spencer (91) figures related shapes

from Henbury and Wabar. In both cases the objects are similar to smoke bombs,

not having suffered any subsequent ablation, as the australites have done. The

dumbbell forms figured from Billiton (48) and Java (108) appear also to be

quite similar to forms found among smoke bombs.

‘The significant facts to be considered in connection with the bearing of smoke

bombs on the australite problem are: (aj the remarkable similarity of the chief

form-types to those of australites, and the relative abundance of cach type;

(b) the fact that while smoke bombs and australites secm to be so much alike.

there is not one form among the slag bombs which is exactly paralleled among

the australites. ‘That is to say: each australite has undergone some secondary

alteration of form.

The suggestion is inevitable that both series were born from burning material

that contained a proportion of siliceous glass, and that blobs of incombustible

silica glass were generated, instantly attaining their primitive forms of sphere,

oval, dumbbell, and teardrop, the first-named of the series being by far the

commonest.

The smoke bombs, however, entered cold air just beyond the engine chimney,

and consequently cooled and fell. he australites, born under conditions that

gave rise to much larger forms, some thousands of times larger, sped through

the air on their spinning flight, wearing by ablation, and thus taking on the

secondary forms that are characteristic of the australites, which are reduced in

size and “flattened’ compared with the smoke bombs (see pl. xi).

This evidence for the dominance of the sphere among the smoke bombs,

combined with the abundance of “round” forms among the australites, is an

important part of the foundation upon which is based the discussion contained

in Section VI. The photographs shown in the accompanying plates support ihe

evidence brought forward in this section.

V. THE POSSIBLE EVOLUTION OF VARIOUS TYPICAL

AUSTRALITE FORMS

In 1934 the writer advanced a theory (ref. 103, p. 132) that all the “round”

australite forms (i.e., round in plan) had been developed from spheres. Effort

will be made here to claborate that theory.

(a) Origin of the Glass Blobs—There was a time in the early stages of

development of the cosmic theory when a belief was held that the tektites had them-

198

selves entered the atmosphere from outside space as a swarm of glass blobs.

Speculation was even made as to the cosmic or lunar origin of such blobs. But

Fletcher Watson (107), Ernst Opik (121), and others have shown that the

amount of heat that could be generated by the passage of such bodies through

the air, considered in conjunction with the heat conductivity of the material, is

not sufficient to melt them to the extent that they obviously have been melted

during the period immediately preceding their arrival on the carth’s surface.

It is clear, therefore, that whatever the actual mode of origin may have been,

it involved the generation of these blobs within the atmosphere in a molten con-

cition, with their instantaneous adoption of the regular forms of spheres, ovoids,

dumbbells, ete. The two sets of internal flow lines, one set associated with the

original spherical form, and one set associated with the frontal melting and How,

are clearly to be seen in the sections shown in plate xi.

We are compelled to assume that, whatever their origin, the sphercs of silica

glass sct cut upon their short, swift journey through the atmosphere as molten

bodies. Moving through the upper air, rotating in a plane normal to the direction

of flight (ref. 121, p. 36), the front and sides of each sphere would be re-heated

by friction, while the rearward surface would cool. At the rear of each flying

sphere would be a space of low pressure and low temperature. ‘he fused material

from the front of the sphere would flow backwards round the body of the object,

evaporating or being swept away, but in special cases adhering to the circum-

ference of the dimimishing sphere, forming the “flange” of the well-known

“button” forms (see sections, pl. xi). During the last portion of the flight the

mass would rapidly cool, after the manner of meteorites generally, arriving on

the suriace of the earth as a solid glassy body. Both internal and external

evidence supports this general hypothesis.

(b) Predominance of Round Forms—The predominance of round forms

among australites is notable. In the Shaw collection (103) there were 1,993

periectly preserved specimens; of these no less than 1,369 (over 68 per cent.)

were round; among the 1,583 fragments in that collection, over 60 per cent. were

derived from round forms. Inspection of other collections of australites confirms

this proportion, It may be significant also, as shown elsewhere in this paper,

that the great majority of silica-glass blobs (smoke bombs) formed in the

chimney gases of locomotives are spheres.

The evolution of the various australite forms is here being considered purely

from the evidence available from “round” forms, for the following reasons:

(7) round forms (lenses, buttons, cores, bungs) predominate to the extent

of two-thirds of all forms;

(ii) round forms present the most definite and clear-cut material upon which

to carry out a series of measurements; and

(1) since the remaining forms (ovals, boats, dumbbells, teardrops) are

gencrally accepted as being derived from the round forms, the con-

clusions based cn a study of the round forms could readily be applied

to the others.

199

There is a very small number of rare aberrant forms that would perhaps

justify special enquiry, such as those known as large bubbles, air-bomhs, peanuts,

coins, pine-seeds, and crinkly-tops; all these can, I think, be explained as examples

of variation from the more common types.

(c)

Characterislics of Round Forms-—Careful examination and measurement

of a considerable number of the round ferms of australites leaves one with a clear

impression of several characteristics :

(t)

(ii)

(iit)

(d)

The general outline of complete forms is bounded by two main suriaces,

each of which is part of a sphere; this has been noted by several

observers from Walcott (30) onwards. (See also pls. x and x1) ;

there is a general harmonious relation between the major diameter

(width) of such australites and the minor diameter (depth); for

instance, the writer’s first effort to establish this connection suggested

that the relation in flanged buttons (neglecting the flange in the measure-

ment) could be expressed by a ratio of 16 to 10, while the ratio for

lenses averaged 24 to 10. ‘This approximate result was sufficiently

encouraging to justify a more complete series of measurements. ;

there seemed indeed to be a third general fact concerning the sizes of

these forms. The largest were always of the large core (“bung”) type,

the smallest were always lenses. while the flanged buttons were always

of intermediate size between these two series;

finully, there was the question of number. Bungs were not only the

laryest of the round forms, but also the rarest, while lenses were not

only the smallest, but also the most abundant. In the Shaw collection,

80 per cent. of the round forms were lenses. Possibly 50 per cent. of

all australite forms are or were lenses.

Graph of Diameter Ratios—lt was decided to investigate these points

by measurement of a number of the most perfect specimens of the round types

available

From the South Australian Museum collection (including the Shaw

collection), by the courtesy of Sir Douglas Mawson and the Director, Mr. H. M.

Hale, and irom my own specimens, the following were selected:

Thirty-eight large cores (bungs), being every complete specimen avail-

able;

Twenty-seven small cores, being all the specimens of this type of which

reliable measurements could be made; these forms are relatively common,

but have a characteristic strong tendency to flake away at their margins;

Forty-two flanged buttons, all the specimens available (the width of

flange neglected in the measurements ) ;

Eighty-two lenses, being a selection of the different sizes from the

largest to the smallest.

In the case of the lenses, however, so abundant are they that another 800

forms were available for measurement, but were not considered necessary. The

200

remarkable preponderance of the lens type will be recalled later as evidence

concerning the development of australite forms.

The range of measurements was as follows:

Vig. 1

Graph showing the ratio of major diameters (width) to minor diameters

(thickness) of 189 selected well-preserved round australite forms. These

ranged from the smallest lenses, through the buttons and small cores, to the

largest type, called bungs. The smallest lens approaches one-third gram

in weight, the largest bung is over 100 grams: this embraces almost the whole

range of sizes. The ratios preserve a remarkable and significant relation to

the forms, and to the relative sizes of these forms, and suggests an evolu-

ticnary development from spheres, through bungs, small cores, flanged

buttons, and lenses.

201

Upon graphing the whole of these measurements, major diameters against

minor diameters, there emerged the very interesting arrangement shown in fig. 1.

It will be seen that the graph bears witness to the truth of the generalization

suggested earlier in this section concerning the progressive development from

sphere to lets, and it also suggesis a great deal more concerning the probable

mode of development of round australite forms.

The graph indicates that throughout the whole scrics of forms a gencral

ratio of measurements is preserved, and that this ratio tends to become greater as

we move downward from the larger “bungs” to the smaller “lenses”. The

relative cventess and unbrokenness of the series, as testified by the graph,

suggests that the specimens available were representative of all the various sizes

and types that occur. ‘here is, moreover, a striking suggestion of an evolutionary

progress in the way the bungs merge into the smaller cores, the latter into the

buttons, and these in turn into the extremely abundant final product, the lenses.

(e) Suggested Evolution of Rowand Forms—Starting from the assumption

that all these “round” forms were developed from spheres, and this is practically

undoubted, we may further develop the series of events suggested by the actual

australite forms and supported by the graph.

The preliminary evidence for the assumption of spheres as the starting point

of all the round forms is:

(i) The abundance of spberes among smoke bomhs ;

(ii) the spherical nature of the remaining “rear” surfaces of round

australites ;

(iii) the evidence of the graph, which suggests an approach to a 1:1 ratio

at a diameter of about 54 centimeters (see fig. 3).

In figure 2 is set out a serics of six progressive stages, intended to represent

the evolution cf the commonest and best known of the australite forms. These

are to be corre'ated with the graph, figure 1.

Stage 1 represents the original glass sphere. Whether shed from a burning

light-metal meteorite (T.acroix, 84; Suess, 87), or swept from the sides of some

more common cometary visitor (Michel, 75; Hardcastle, 76), or shot out from

some other hot siliceous centre, these spherical forms took their shape at the

instant of their separation from the parent body. From the known facts con-

cerning the temperatures and the fusion of meteorites, these spheres must have

commenced their journey through our atmosphere from somewhere less than

70 miles above the carth, at a temperature close to their melting point. On account

of atmospheric ablation none of these spheres, as such, reached the earth’s surface.

Stage 2 represents the development after perhaps one or two seconds of

atmospheric flight. The “back” (upper) surface is often pitted by the bursting

of small gas bubbles that came to the surface in that low pressure area. ‘Vhe

“front” (lower) surface has re-melted under the heat gencrated by atmospheric

friction, some part of this’ material has flowed backwards along the sides of the

sphere, and a considerable part of the front and sides of the material within the

202

sphere itself has re-melted and developed “strain” lines. (See also pl. xi.) With

the rapid cooling of the hotter portions of the bodies that reached the carth while

at this stage an unstable condition of the glass resulted, so that they tended to

lose much of their material by cracking and flaking, leaving the more stable portion,

the centre and back (that had cooled less quickly), to be preserved in the

characteristic shape known as the bung (see the upper dotted line in stage 2).

This is the general shape of all the larger round unworn australites,

Stage 3 represents the next development, no more than a progressive ablation

and back-flowing of the material in the front of the spinning blob. The facts

Sketches of cross-sections of a series of six stages in the development of

australites. Stage 1 (the sphere) is hypothetical, but it cannot be doubted

that it was the initial form in the great majority of cases, Stages 2 and 3 are

hypothetical in part, being drawn to represent the probable shapes between

stages 1 and 4; but the central more stable portions of these forms are well

known, that of stage 2 as the bung, and that of stage 3 as the small core.

Stages 4, 5, and 6 are representations of actual common forms. The sketches

should be correlated with figure 1, and compared with the photographs in

plates x and xi,

suggest that at this stage there is an even more marked instability of the

“equatorial” portions, so that cracking and flaking of the solid specimens are more

common, and from this stage we get the smaller cores. These. though they have

usually well-preserved back (upper) surfaces, are much more deeply and more

irregularly flaked on their sides and fronts than any other australite forms. The

shape of the cores at this stage is suggested by the upper dotted line. The

203

assumption in the figures of a flange for stages 2 and 3 is pure speculation, based

on analogy with the flanged button (stage 4). Stages 2 and 3 may have had no

flanges at all: there is no positive evidence available. Indeed, the evidence quoted

in reference 112, pages 130-131, suggests that in some cases at least there was no

flange present in the large cores and bungs.

There is clear evidence in the transition from flanged button to unflanged

lens, to prove that the backward-flowing melted material did not as a rule procced

beyond a certain line. Here apparently the molten material was affected by the

probable intense cold of the sheltered rear low-pressure zone, so that the glass

material solidified. As later suggested, there may have been some exceptional

cases where the conditions permitted matcrial to flow farther back.

Opik (reference 121, page 47), speaking of the liquid that flows backward

from the front and sides of a speeding meteorite, remarks that it “is collected in the

portions less exposed to aerodynamic pressure (reat side, especially rear pole of

rotation).” This may be so for meteoritic irons or stones, but it is clearly not so

in the case of glassy blobs, as witnessed by the external form of the flanged

buttons (pl. x), and more definitely by the photographs of thin sections of

buttons (pl. xi).

Stage 4 represents an actual, characteristic cross-section of a flanged button.

At this stage more than half the material of the sphere has disappeared. It is only

at or before this stage that the conditions permit of the development of the

beautiful flange that forms the most arresting feature of the button type. At

earlier stages this material was either swepl away or has flaked off; at later

stages (5 and 6) only the rear portion of the sphere is preserved, as a lens.

It is at this stage that a more stable condition of the whole mass is reached, and

though flaking and fracturing due to internal tension are testified to by numberless

button fragments, there are still numbers of flanged buttons perfectly preserved,

while all such larger forms as cores and bungs are invariably diminished by flaking.

Flanged buttons are the largest forms that preserve the regular waves of flow

upon their forward surfaces.

Stages 5 and 6. These are two successive stages in the final development of

the round forms. Thus are formed the Icnses, larger and smaller. The largest

lenses have major diameters that are just cqual to the zone beyond which the

backward-flewing glass of the flange did not normally advance.

‘The smallest known lenses are so tiny that only the acute vision of the

aborigines would ever have detected them among the sands and rubble that cover

the carth’s surface where most of them were picked up. Doubtless there were

smaller lenses that have never been found, or that have been too fragile to resist

fracture. Doubtless also many spheres went beyond this stage of devclopment

during their journey, being completely consumed. Eighty per cent. of all the

©) There are a few rare examples of australites in which the backward-flowing

material appears ta have advanced beyond the poiuts shown in stages 2, 3, and 4 of

figure 2. Among these T would place the “crinkly tops” (ref. 103, type A2g, 69, pl. ixF)

and the curious forms figured hy Dunn (ref. 67, pl. xxiii).

204

original spheres were ablated down to the Iens stage, so far as the evidence of the

Shaw collection is concerned.

(f) Relations of Forms and Siges—Some natural speculations follow this

analysis. If all the original spheres had been of the same size, of the same

temperature, composition, and speed, and had the same distance to travel through

the air, there would have been one similar type of final product: lens, button,

core, as the case may be.

We know them to bave kad approximately the same chemical composition.

It is reasonable to asstime equal temperatures within certain limits. Measure-

ments oi the residual spherical surfaces show, however, that the primary spheres

were of many sizes, up to about five centimetres diameter. The chief causes of the

difference in the stages at which these glass spheres reached the earth, it is sug-

gested, were variations in the distances travelled, and in the speed of travel, both of

which factors must have varied according to the direction in which the objects

moved relative to the earth’s surface and to the moving body from the surface

of which they are presumed to have been swept. We must remember, also, that

the parent meteorite was probably rotating, thus giving a variety of speeds and

directions to the glass blobs.

A special effort was made to determine the actual sizes of the original spheres

of the five separate australites shown in plate x. These proved to be as follows,

and give some idea of the actual range of sizes of the original spheres:

(i) The bung type - - - - 4-7 mm. diameter

(ii) The core type - - - - 31,

fut) The button type - - - 16, 4

(iz!) The large lens type - 4 ~ TK oy hi

(v) The small lens type - - - ASO 4g f

These measurements correspond with and support the theories elsewhere

put forward in this paper concerning the spherical origin of “round” australites,

and also the range of sizes. The original glass sphere from which the “bung”

was derived was somewhat over 100 times as large as the original sphere that

resulted in the “small lens.” It will be noted also that, although the button looks

larger than the Jens (pl. x), on account of the flange, it was actually derived from

a somewhat smaller original sphere.

In figure 3, curves A and B, there appear to be two conclusions which support

cach other. Though arrived at from a basis of fact, the conclusions are equally

hypothetical. In A, a median curve, drawn from the data of figure 1, is con-

tinued upwards; the sphere type is found (ratio of diameters 1:1) at about

53 cm. ‘This may be interpreted to mean that the largest original spheres were

of this size. ‘The graph confirms the harmonious relations that suggest the

development from spheres of the forms measured, but is valuable more for its

suggestiveness than for any definite numerical implication; the value of the upper

part of the curve is lessened by the fact that the measurements are of specimens

that had undergone flaking since their formation.

205

In the second curve, figure 3 B, the numbers of specimens are sct out in

groups according to size. First group, up to 1 cm. diameter; second group,

1 to 2. cm. diameter; and so on, The latter part of the curve is quite clear, and

indicates the rapid decrease in numbers of the larger specimcus, with a suggestion

that there were few or no specimens larger than 54 cm. diameter.

In the first part of curve B, however, there is some uncertainty. The actual

numbers of the smallest group are less than those of the sccond group. But there

is reason to believe that there may actually be much higher numbers of the small

distribution given previously (reference 103, page 78). ‘The part of the curve

marked P is an alternative interpretation, suggesting that the great majority of

forms were very small and remain uncollected.

(g) Comparison with the Stony Metcoriles—An idea of the possible manner

of the shecding of the glass blobs may be gained from a microscope study of

the fused surface of a stony meteorite. There the thin skin of fused vitreous

residue bas the appearance of a scries of irregular waves and wrinkles. In places

the material is arranged in long sub-parallel wave-like ridges, probably formed

at right angles to the direction of movement. The ridges rise higher at some

206

points than at others, and one could imagine the “knobs” or crests becoming

large enough to be swept off from the meteorite surface as independent blobs.

(h) Conclusions—Summing up the evidence of this section we have these

tentative conclusions:

(7) most of the original australite blobs were spheres ;

(ii) during their spinning flight they were reduced in size in a regular way,

developing ultimately to the button and then to the lens stages ;

(iii) a small percentage never developed beyond stages 2 and 3;

(iv) somewhat more than 5 per cent. reached the stage of flanged buttons;

(v7) the majority (80%) remained in the air long enough to be ablated away

to stages 5 and 6, the lenses.

(zi) possibly others were completely evaporated during flight.

VI SPECULATIONS CONCERNING TITE THEORY OF

COSMIC ORIGIN

Every theory of terrestrial origin that man’s ingenuity has becn able to put

forward during 150 years of discussion having now been elaborated, discussed,

and for the most part rejected, there remains the theory (or theories) of cosmic

origin.

Many workers, themselves inclined by the facts of their experience towards

the cosmic theory, have expressed an opinion that the only method of proving

this theory would be the witnessing by man of an actual shower of glass

meteorites. That would indeed be an excellent confirmation, devoutly to be

wished, but it is unlikely. Meantime, other workers are steadily moving onward,

selecting fresh criteria, and endeavouring to discover positive evidence to prove

from the available material that tektites are of cosmic origin,

Even if we accept the meteoritic or cosmic theory, on the grounds that it is

the only one that satisfies all the known conditions, we are still far away from

an ultimate solution of the problem.

Let us take, for example, the most popular of the cosmic theories that have

lately been entertained and discussed, namely, that of a burning, light-metal

meteorite (or a “swarm” of such meteorites) passing above the earth and shedding

its content of silicous material in small glassy blobs. We may endeavour to apply

this theory to the australite problem, but it seems clear, from the numerical facts,

that we must postulate a swarm of meteorites, and not a single meteorite.

The strewnfield of the australites (114, page 134) covers over 2,000,000

square miles of land; it is over 2,000 miles from south-east to north-west, and

about 1,500 miles in width. It is generally agreed that the “shower” travelled

from south-east to north-west, though there is no actual evidence that it did sO;

the direction of travel might even have been at right angles to this.

In the case of the moldavites there is a narrowing of the strewnfield from

west to east, as well as an accompanying change in physical characters (125).

With the australites, Summers (52) suggested that there was a variation in

207

density towards the west, and Hardcastle (76) stated that more of the larger

forms fell towards the west. But these suggestions have not been followed up,

and there is no extensive evidence of appreciable difference in average composi-

tion, density, or size across the area.

We may first try to form a mental picture of a meteorite swarm travelling

for over 2,000 miles through the air, relatively close to the earth’s surface (within

70 or 80 miles), and continuing to burn throughout the passage. ‘Uhis brings up

questions of speed, path, weight, friction, heat, and so on, as well as of the manner

in which the glass blobs were swept off the parent body. First, we shall consider

temperatures and conductivity.

In considering these aspects of the problem I have had the privilege of many

discussions with Mr. G. F. Dodwell, B.A., Government Astronomer of South

Australia, and he has kindly supplied the following statement, with permission

for its inclusion here:

“The mechanics of meteor phenomena are not easy. Opik, of Tartu Observatory

(Esthonia), has a very interesting and long paper on it, containing a great deal of helpful

information and calculation (ref. 121). In his Table VI he gives the characteristics of

fusion for a stony meteorite. In this, R is taken as the radius of the solid nucleus,

AR the effective thickness of the liquid layer (a liquid surface condition being the result

of friction in the carth’s atmosphere), T is absolute temperature, AT is the temperature

difference between the surface of the liquid film, and the bottom of the film (taken as

constant at 1800°, the temperature of fusion, which, he says, is effectively the same as

for iron); M is the apparent stellar magnitude of the meteor, and W its velocity. The

table then is:

R=1cm. R=0:lem., R = 0-02 cm.

| AR AT M | AR AT M | AR AT M

W. Cm. | Cm. 4 | Cm.

16 Km./Sec. 0-035 (24,000°) —-1 0-011 sone 7 | 0-005 70°) 13

40 ‘fale 0-054 (92,000°) —-5 0-017 (3,100°) 5 | (0-008) 270° 10

90 fy wt 0-081 (320,000°) -9 | 0-026 (10,000°) 2 (0-012) 870° 7

“We might take 1 centimeter radius as representing a medium-sized australite. Then

for R=1 cm. the values of AT are enormous; this means that the layer never reaches

the computed thickness AR, but starts boiling when its thickness is of the order of

1,000

; such a thin layer sticks to the surface by reason of viscosity.

ARx

“Thus for R= 1 cm. the substance of the nucleus is practically vaporized, so to speak,

on the spot, the thickness of the liquid layer being of the order of 0-001 cm. only; most

of the solid nucleus remains cold inside. This case evidently resembles the phenomena

obseryed in large metorites reaching the ground.

“Opik concludes that stone meteors brighter than the seventh apparent magnitude

are vaporized from the surface of a thin liquid layer, the nucleus remaining solid. This

agrees with what Nininger says in ‘Our Stone-pelted Planet, page 29, where he gives

his belief that owing to the brief flight of a meteorite through the air, only a few seconds

(in general 3 to 6 seconds), the surface heat for ordinary-sized meteorites is unable to

penetrate into the interior, which remains cold. On page 89 he says that the envcloping

crust of fused material is, in most cases, about five-tenths of a millimeter in thickness.

This motten Alm is being constantly swept off and dissipated by currents of air sweep-

208

ing across the face of the meteorite at the rate of several miles per second. On page 89,

also, he gives the upper limit of visible meteors as approximately 70 miles above the earth.

“On page 24 he gives the average heliocentric velocity of meteorites as 26:2 miles

per sccond, As the carth’s velocity is 18-5 miles per second, this gives the range of

velocity of meteorites, according as they are travelling with or against the earth’s direction,

26°2— 18-5 = 7-7 miles per second, up to 26-2 + 18:5= 44-7 miles per second. This

agrees with the data in the Von Niessl-Hoffmeister Catalogue of 611 great meteors, and

analysed by Maltzev. The range of geocentric velocitics is given there as from 6 to 43

miles per second (Popular Astronomy, April, 1937, 213).

“In view of Opik’s calculations, it seems to me difficult to reconcile the occurrence

of australites with the disintegration of a large meteorite, weighing many tons, and

travelling over the required distance. Is it possible for such a large meteorite to travel

such a distance, say 3,000 miles, at only 70 miles or less from the surface of the Earth,

without being drawn in by gravitation within a small fraction of that distance? Examining

this with reference to say an 8-inch globe, the moving body, reduced to scale of the model,

would have to traverse a circular path, parallel to the globe and only one-tenth of an

inch above it! On the other hand, of course, one thinks of the exceptional case of the

‘great meicorite procession of 9 February, 1913’ (See P. Astr., Feb., 1938, 109.)”

Nininger’s reference to the meteorite procession of 9 February, 1913 (“Our

Stone-pelted Planet,” pages 85-86) includes the following: “This great procession

of meteors was witnessed along a course of 5,700 miles. It consisted of six to

ten groups of fireballs, four to six in each group. ‘They procceded across Canada,

to the south-east, growing more brilliant as they went; they seem to have plunged

into the sea somewhere south-east of the Bermudas.” C. P, Olivier (“Meteors,”

page 242) says that the procession seems to have consisted of “ten groups, with

20 to 40 members in each group. In Canada it is said to have taken 3-3 minutes

to pass a given place.” See also La Paz (122, page 227).

We see, then, that the track of the hypothetical australite meteor swarm, so

far as distance is concerned, is within the bounds of what a meteorite group has

actually been observed to do.

We have now to account for the width of the area over which the blobs have

been scattered. This, as already stated, is about 1,500 miles. We may assume, as

is commonly done, that the australite shower was derived irom a group of

meteorites travelling from the south-east to the north-west. The problem is

somewhat similar whatever direction we assume. If, however, the direction were

from south-east to north-west, the period of travel across the strewnfield would

possibly oceupy no more than 45 seconds; if from north-west to south-cast, this

period would be nearer five minutes.

Tt must perhaps be emphasised, for the information of those unfamiliar with

the strewntield of the australites, that there can be no doubt that their widespread

distribution is associated with the manner of their coming. It is not something

done subsequently either by man, or birds, or winds, or glaciers. All these

theories have been advanced and rejected. When the australites arrived at the

surface of the earth they were spread over the area shown, approximately, in the

map on page 134 of part If of this series of papers,

This means that the hypothetical parent meteorite swarm, something less

than 70 to 80 miles above the earth, travelling at from cight to forty-five miles

209

per second, according to direction, must have flung blobs of glass, broadcast

fashion, over 750 miles to either side. There was nothing comparable to this in

the Great Meteorite Procession of Canada. Nininger says, “Detonations and

earth tremors were caused along their pathway to a distance of 20 to 70 miles on

either side.’ So far as we know, no actual blobs were shed from these meteorites,

and the observations suggest a very narrow range of influence. We must recall,

however, that this was a meteoritic “procession,” presumably a long line, one

behind the other; we may conceive a meteorite swarm that moved with a wide

and irregular front.

In order that we may better discuss the problem of distribution, let us con-

sider the question of the total size of our hypothetical meteor swarm, ‘The total

number of australites is estimated at from one to ten millions. The average weight

per specimen is one gram, and the average w eight for each original blob, say,

three grams. This gives a total of from 3,000,000 to 30,000,000 grams, approxi-

mately, and involves a minimum of three Lons of silica- glass up to a maximum of

thirty tons.

There is no means of knowing with what amount of combustible metal this

had been associated, but it may net be unreasonable to suggest the siliceous

content at 10 per cent. This gives 30 to 300 tons of material in our meteor swarm.

This is necessarily a very approximate and tentative estimate, just to give some

definition to this aspect of the discussion.

Tt is difficult to form a satisfactory mental picture of this hypothetical meteor

swarm, shedding its silica content across 750 miles on either side. Moreover,

although there are possibly few parts of southern Australia that did not receive

some of the australites, specimens are very rare over some areas and very

abundant over others. The areas of abundance are not along the central

axis of the strewnfield, nor in any regular arrangement.

So far as width is concerned the T.eonid swarm of meteorites, in its most

densely packed part, is from 100,000 to 120,000 miles in diameter (estimates by

Sir Robert Ball and C. P. Olivier); there are also cometary bodies with com-

parable size. It is thus not inconceivable that the particular meteorite swarm

that gave rise to the australites should have extended over a path some 1,000

miles or more in width, and we shall assume this to have been the case.

VIL SUMMARY OF HYPOTIILESIS

Following upon this account of the tektite problem, as viewed from a study

of the australites, it may be worth while to formulate a specific hypothesis as a

basis for further discussion.

The suggestion is therefore put forward that, in the case of the australites, at

a time “geologically recent but historically remote,” the earth was visited by a

large and widespread swarm of combustible metallic meteorites. The swarm was

not less than 30 tons, and possibly 300 tons, in total weight, containing (say)

ten per cent. of siliceous material. The component bodies travelled across Aus-

tralia in a wide and irregular formation on a front of 1,000 miles or more, at a

210

height of 80 miles or less, burning as they went. Possibly some were burnt up

relatively early, while others entcred the atmosphere later and farther on. The

period of transit of the swarm across Australia occupied at least 45 seconds and

at the most five minutes... Their residual incombustible siliceous content was shed

in molten glass blobs, these being for the most part swept backwards by the rush

of air from the rotating parent bodies, and thence shot outward in many direc-

tions. The glassy blobs, to the number of from one to ten millions, averaging

about three grams in weight, sped to the carth, rapidly rotating and undergoing

ablation and flow from their forward parts, reaching the earth’s surface in from

three to six seconds, having been chilled to solidity during the last portion of

their flight. The blobs, as they formed, instantly assumed the shapes of spheres

and allied forms common to rotating liquid bodies, and these by ablation were

reduced to the lens, button, and other form-types known as australites, They

were thus distributed in an irregular way over the southern portion of the Aus-

tralian continent.

DESCRIPTION OF PLATES

PLATE X

Upper: Three views of typical specimens of round australite forms: (a) bung,

(b) small core, (c) button, (d) large Jens, (c) small lens. The first row shows the top

(rear) view, the second row shows a side view, and the third row shows an oblique view.

These are the form-types dealt with in figures 1 and 2. (The largest specimen shows

the sub-radial groovings that are found occasionally on the upper surfaces of the largest

australites.)

Lower: Photograph of the characteristic types of smoke bombs. Spheres pre-

dominate in the material collected from railway engines, as shown in the photograph on

the left side. In the right-hand photograph a selection has been made to show various

fess common forms that occur. The range of specimens in the latter photograph varies

irom one “giant” round form of 1 mm. diameter, down to a tiny specimen of bent dumb-

bell type that was apparently blown on to the slide as a dust fragment; left side x 4;

right side x 7. Microphotos: R. A. L. Laughton.

PLATE XT

Upper: Two photographs of thin median section of flanged buttons, x 4, repro-

duced from negatives made for E. J. Dunn, Bull. 27 (ref. 50), and lent by the Mines

Department of Victoria. These photographs show the internal flow lines in two series,

as postulated in this paper, and also show certain characteristics of the upper (rear) and

lower (front) surfaces of australites. The secondary frontal melting and flow towards

the equator into the flanges is well shown; in the lower specimen part of the flange has

been lost and a new one is in process of formation.

Lower: Magnifications of the smoke bomb (slag bomb) forms, x 20, to emphasise

the differences between (a) the primary forms of the molten blobs, and (b) the ablated

and diminished forms characteristic of australites, the latter x 3. When seen “side on”

the smoke bombs are the same as they appear from a top view; the side-on views

of australites show the results of ablation and the development of flanges and rims.

IT INTRODUCTION

Even a casual survey of the specimens of South Australian Scaphopoda,

and of the literature upon them, reveals much confusion and haphazard identifica-

tion of species. The following short account is, therefore, submitted as an

attempt to point out discrepancies to those students w ho find difficulty in the

correct naming of already known forms.

Both recent and fossil specimens have been examined, the latter chiefly from

the Tate Museum, Adelaide University (including the Abattoirs Bore material),

and the Commonwealth Palaeontological Collection at Canberra, The recent

shells are well represented in the South Australian Museum in the Verco Collec-

tion, which has provided data for the elucidation of numerous errors in previous

accounts of the Scaphopoda.

TI RECENT SPECIES

‘The majority of the recent South Australian Dentaliwm species form a fairly

distinctive subgenus, Paradentalium (subgenotype D. bednall: Pilsbry and Sharp,

1898), introduced for shells with six to fourteen intercal ating ribs, usually con-

tinuing to the aperture or becoming obsolete, the intervals apparently smooth but

microscopically concentrically and longitudinally striate ; apex small; orifice simple,

without terminal pipe, slit or notch,

In this subgenus can be included D. bednalli, D. octopleuron, D. hemuleuron,

D. francisense, PD. flindersi sp. nov., and D. lasmaniensis.

In the second subgenus Eudentalium (genotype D. quadricostatum Brazier )

Cotton and Godfrey, 1933, we place D. beachportensis sp. nov.; the subgenus

being distinguished by the small, solid, square tube, serrate primary ribs and

Trans. Roy. Soc. S.A., 62, (2), 23 December 1938

218

smooth interstices. The two specics D. bordaensis sp. nov. and D. hyperhemi-

leuron probably belong to the subgenus Episiphon Vilsbry and Sharp, while

D, verconis sp. nov. and D. jaffaensis are placed in the subgenus Fissidentaliuim

Tvpe Locality—Gulf St. Vincent, S. Aust.

This is the correct name for the shell previously known in South Australia

as D. intercalatum. Cotton and Godfrey, in introducing the subgenus Paradenta-

fit, based it on the South Australian species D, bednalli Pilsbry and Sharp,

but D. intercalatuin Gould was quoted as genotype following Verco’s incorrect

identification of the South Australian shell. The South Australian species had

already been described as D. bednailli Pilsbry and Sharp, and that was the species

under discussion. ‘The latter should now be regarded as the subgenotype.

D. katowense and D. decemcostatum have also been incorrectly used for

some South Australian specimens of this species. The nearest allied species is

D. tasmaniensis T. Woods (north-west coast of Vasmania) which has been

recorded from Port Adelaide, but is not represented in our collection from South

Australia. Subfossil specimens so named from the Port Adelaide River are

somewhat intermediate between D. bednalli and DD. tasmaniensis; mature

specimens show the typical intercalate ribbing of the so-called South Australian

“mtercalatum,

Shell of medium size, very slightly curved and very gradually tapering,

circular, polished, white; accremental striae fine and regular; aperture round,

peristome thin; apex large with a narrow tube projecting from the centre of the

disc, closing the posterior end; this appendix is visible in very early life, when

the shell is extremely narrow. In the still carlicr stages of growth, when the

appendix is absent, the shell resembles J). jaffaensis, but has straighter sides, as

it does not widen so rapidly; the present specimens have more marked concentric

Shell large, white, very solid, slightly curved towards the posterior end;

aperture irregular, dorsally produced; peristome thin and sharp, displaying the

numerous longitudinal ribs; apex fairly large, orifice small, walls thick; a simple,

short, ventral fissure about 2 mm. in length; sculpture of numerous (about twenty )

primary, narrow, rounded ribs at the anterior end, of subequal strength, with

only two cr three in all minor intercalations; interspaces wider, both ribs and

interspaces crossed by regular, fine, cblique, growth-striac.

Dimensions—Length, 47 mm.; breadth, 6 mm.

Type Locality—Beachport, S.A., 200 fathoms.

Recent, Flindersian, deep water,

Observations—This species has been recorded as D. selandicum Sowerby

protoconch an elliptical bulb with a very short, slightly contracting, round, tubular

posterior prolongation set somewhat obliquely to the axis of the bulb and directed

222

towards the convex side of the shell; opaque transverse rings appear in the first

1-5 mm. of the shell, and the adult has a slit at the posterior end on the convex

or ventral side.

Dimensions—Length, 24 mm.; breadth, 2-7 mm.

Tvpe Locality—Cape Jaffa, S.A., 90 fathoms.

Recent, Flindersian, deep water.

Observations—Related to the Peronian LD. lubricatum Sowerby and D. virgula

Hedley, but more slender, straighter, and less rapidly expanding than

D. lubricatum.

WI FOSSIL SPECIES

For the most part, fossil species have provided little difficulty. Almost all

were described by Tate in 1887 and 1899, lists of localities being published in each

case. Further localities have been recorded by Chapman in his work on the

Mallee and other Victorian bores, including (with Miss I. Crespin and R. A.

Keble) the Sorrento Bore, and by Howchin in papers upon bores in the Adelaide

basin. Additional localities are here listed, specimens from which, unless other-

wise stated, are in the Commonwealth Palaeontological Collection at Canberra.

223

Type Locality—Oligocene, The Cliffs, Nelson, New Zealand.

The very lengthy synonymy of D. mantelli is here reduced to references con-

cerning Australia only; those relating to the occurrence of the species in New

Zealand are listed by Suter, N.Z. Geol. Surv. Pal., Bull. No. 2, (4), 32.

This is a very variable species, common in both Australia and New Zealand.

It presents difficulty in that the early references do not properly designate the

type. Both Zittel and Suter place The Cliffs near Nelson first in the list of

localities, thus apparently excluding Mantell’s Onekakara shell. It seems that

one must accept Zittel’s figured specimen from The Cliffs as the holotype, which

Suter states is in the K.K. Héfmuseum, Vienna.

The type locality, morcover is a poor collecting ground, so that it is difficult

to obtain specimens of true mantelli, Tate (1877) states that a comparison of

authentic specimens was made by him; Suter’s figures of plesiotypes agree with

Australian specimens, in view of which we here retain the identity of the Aus-

tralian with the New Zealand species.

Holotype—Tate Mus. Coll., Adel. Univ.

Shell large, white, boldly sculptured with intercalating ribs numbering in the

holotype 13; interstices average about the width of the ribs or a litt'e narrower;

the ribs split towards the anterior end by gradually deepening sulci; accremental

striae irregular and rather coarse in places; aperture rounded, peristome regular,

fairly thick, undulated on the exterior by the section of the ribs; posterior open-

ing small.

Dimensions—Length, 45 mm.; breadth, 7 mm.

Type Locality—Ahbattoirs Bore, S.A., Lower Pliocene (Howchin “Ade-

laidean,’’ Upper Pliocene).

Paratypes—In various specimens, the number of primary ribs varies from

7 to 16; splitting of the ribs towards the anterior by gradually deepening sulci

frequently doubles the number of ribs.

Observations—This is a very variable species, related to D. mantelli, from

which it differs in being much more boldly sculptured and in having a dominant

intercalating system of ribs. It is somewhat like the common New Guinea fossil

species D. subrectumm Mart., which has narrower ribs.

THE CLIMATE OF TROPICAL AUSTRALIA

IN RELATION TO POSSIBLE AGRICULTURAL OCCUPATION

By J. A. Prescorr

[Read 14 July 1938]

INTRODUCTION

The study of agro-climatology has received considerable impetus during

recent years owing to the concept of climatic factors which simultaneously take

into account rainfall, temperature and relative humidity and which can be related

to soil moisture. Reference may be made to the recent summary of the principles

involved (Prescott, 1938) and, as regards the practical application of the method

to an agricultural problem in South Australia, to the work of Trumble (1937).

The purpose of the present contribution is to analyse the factors, principally

those relating to moisture conditions, that are likely to determine the trend of

agricultural and pastoral occupation in those parts of Australia which lic north

of the Tropic of Capricorn, with particular emphasis on the areas receiving

seasonal rainfall typically monsoonal in character. For purposes of comparison,

a similar analysis has been made of the climate of Nigeria, using the data of

Brooks (1916, 1920), which data have been amplified by personal access to the

records of tie London Meteorological Office, through the courtesy of Dr. Brooks

himself

The parallel between tropical Australia and West Africa is only complete for

the strictly monsoonal areas; the east coast of Australia is a trade wind coast,

whereas the wetter parts of West Africa have an equatorial climate. A comparison

with the French territories of Senegal, Upper Niger and Upper Volta would

possibly be more instructive as lying in latitudes more similar to those of tropical

Australia, but the data for these territories are not so complete nor so readily

accessible as those for British Nigeria.

In the analysis of the data, use has been made of the ratio of the mean

monthly rainfall to saturation deficit, the first expressed in inches of rain and the

second in inches of mercury. No data for evaporation are available for the Aus-

tralian area under consideration except for Boulia, which is on the desert margin.

An evaporimeter tank has only recently been installed alongside the aerodrome

in Darwin.

Monruty Rarios oF RAINFALL TO SATURATION DEFICIT

Two critical values for the ratio cf rainfall to saturation deficiency have been

adopted. The first, a monthly ratio of 5, is based on the previous work of

Prescott (1936, 1938) and Trumble (1937) and represents the limiting ratio

required to keep the surface soil above the wilting point of plants. Where this

value is not reached for any of the twelve months of the year, desert conditions

may be expected to prevail; the length of the agricultural or pastoral season can

be regarded as the period during which this value is exceeded.

Trans. Roy. Soc. S.A., 62, €2), 23 December 1938

230

‘The second monthly ratio is that of 35, which is based on the evaporation

from a saturated soil or from an actively growing dense crop under ideal condi-

tions. Under either of these conditions the evaporation from the soil or crop

tends to a value of about 1°6 to 1-7 times that from a free water surface, and

it is obvious that more rain will be required than that just sufficient to balance

the evaporation from a water surface if the native vegetation or the crops grown

are to be vigorous.

These ratios of the rainfall to saturation deficiency have therefore been

calculated for the tropical stations of Australia from the data published in

Pamphlet No. 42 of the Council for Scientific and Industrial Research and the

isologs of the ratio mapped from the values so obtained and by interpolation on

maps on which were successively superposed altitude, temperature, humidity,

saturation deficit and rainfall. The maps showing the values of this ratio for the

twelve months of the year are shown in figs. 8a, 8b, and 8c, in which the march

of the monsoon into tropical Australia can be readily observed. The possibility of

agricultural or pastoral occupation will be determined, so far as climate is con-

cerned, by these monthly trends.

This series of maps reveals that the greater part of tropical Australia is

subject to seasonal drought for cight months of the year, and that the very wet

conditions corresponding to a ratio of P/s.d. of 35 prevail only for three months

of the year along the northern coast line, and with small areas along the east

coast with up to eight months as at Innisfail in North Queensland.

During the driest months a narrow belt which is practically completely rain-

less moves westward, starting in August from the south-west coast of the Gulf

of Carpentaria, moving along the coast of the Kimberleys, finishing in October,

and continuing in November at Onslow in Western Australia. A further feature

indicated in fig. 1A is the small area, including Townsville, Charters Towers and

Ayr, which has the benefit of the “lesser rains” for a brief period in mid-winter,

the prevailing low temperatures enabling a relatively low amount of rain to be

efficient in maintaining soil moisture. This period cannot be regarded, however,

as a reliable feature of the local climate.

LENGTIE OF SEASON

The essential facts with respect to the length of the season are indicated in the

maps of fig. 1, where the number of months during which soil moisture condi-

tions may be considered to be satisfactory (P/s.d. being greater than 5), and

where conditions of real wetness prevail (P/s.d. being greater than 35) are

indicated as isochrones. This pair of maps may be compared with the tropical

part of the bioclimatic map of Davidson (1936), the principles employed in their

construction being essentially similar to those employed by Davidson.

These maps reveal that the characteristic feature of the climate over most

of the area is its extreme seasonal character, the length of the seasonal drought

being as important as the length of the wet season and determining to a con-

siderable extent the character of the native vegetation. The geographical limits

231

of the grasslands and open savannahs on heavy soils correspond approximately

to the seasonal isochrones of three and four months. With a scason of from four

to six months in length, savannah woodlands prevail. Where the middle months

of the rainy season are very wet, local swamps become important in low country

and sclerophyll forests are encountered on the higher ground. The true rain

forests of the Queensland coast are associated with short seasonal droughts and

with several months of very wet conditions. Many so-called rain forests in the

monsoonal belt are essentially “corridor” forests along the banks of permanent

rivers, and the trees and palms growing in them are usually capable of with-

standing a considerable degree of atmospheric dryness. The trees of the savannah

woodlands and savannahs are also adapted to the dry conditions of the winter

and many of them, typified by the Bauhinia, lose their leaves at the end of the dry

season.

An excellent comparison and contrast for two localities having semi-hunid

climates with seasonal rainfall is afforded by that between Adelaide and Darwin.

Both are near the coast of a large gulf protected by a large island. The rainfall

si)

252

in Adelaide falls in winter, that in Darwin in summer, the length of the wet

season being in each case 6°6 months. It is the drought period which is of some

significance—the mean saturation deficit for the winter six months at Darwin is

0-40 inches, and in Adelaide for the summer six months it is 0°42 inches, so that

evaporation in the dry season is probably the same in both places. The mean

temperature for the winter six months in Darwin is, however, 81° F., while in

Adelaide for the summer six months it is only 70°F, Adelaide is in the heart

of a thriving agricultural community based on the cultivation of Mediterranean

annual crops and drought resisting perennial trees and pastures. Any possible

agriculture in the vicinity of Darwin must similarly be based on specialized crops

suited to monsoonal conditions.

AGRICULTURE AND SEASONAL RAINFALL

Betore proceeding to a further discussion of possible agricultural develop-

ments in tropical Australia, it would be well to define the climatic requirements

of an agricultural system based on the acceptance of a period of seasonal drought.

Experience at the Waite Institute, near Adelaide, may be taken as affording

some evidence. The crops successfully grown are wheat, barley and oats, the

principal grasses and all the clovers are Mediterranean annuals. Perennial grasses

and forage plants are limited to Phalaris, perennial rye grass selected for drought

resistance, the native grasses such as Danthonia and Themeda, and lucerne, The

climate ts too cold in winter and too dry in summer for cocksfoot or for red and

white clover. Both peas as a crop and subterranean clover as a pasture plant

need to be selected for earliness, so as to set seed before the beginning of the

summer drought. Being shallow rooted they are not able to rely on reserves of

subsoil moisture. The monthly trends of the ratio of rainfall to saturation

deficiency at this centre are indicated in fig. 2, in which the relationship of

these ratios to the agricultural season for different crops is also shown

diagrammatically.

In the same diagram is set out information regarding two centres in Nigeria,

Nano and Ilorin, for both of which cropping records are available in the Bulletins

of the Nigerian Agricultural Department (1930, 1931). Kano is typical of the

true monsoonal belt and, as will be noted later, the seasonal rainfall js equal in

amount to that of Katherine in the Northern Territory. The crops that are

possible are strictly limited to those suitable for short seasons. Kano is the most

important Nigerian centre for the cultivation and export of the peanut. Lorin

is transitional in climate between the monsoonal and equatorial regions. Both

early and late sown maize are possible at this centre, although the latter is rare,

yains become important as a crop. The most important tropical grain crop is

guinea corn (Sorghum vulgare). Where the seasons are shorter and the rainfall

less, guinea corn is replaced by bulrush millet (Pennisctum typhoides). It is to

be noted that farming is practised to the northern boundary of Nigeria and for

some distance beyond, into French territory. In the far north-east, Geidam, with

233

a rainfall of 14-3 inches and a season 2°4 months in duration, is on the extreme

boundary of agricultural occupation.

A grcat assortment of crops has been listed for the West African territories,

and an equally great variety for any one crop. Reference in this connection may

As the whole of Nigeria with the exception of the region of Lake Chad is

potentially agricultural, a detailed comparison between the climates of selected

stations in tropical Australia and in Nigeria may next be attempted. ‘he

isochrories of the length of the agricultural season in Nigeria are shown in the

map of fig. 7, which is also a guide to the localities discussed in the text, The

comparison between the pairs of stations has been done diagrammatically in

figs. 4and 5. Three aspects are to be compared; these are: (1) seasonal rainfall,

(2) length of season, (3) temperature. The differences in latitude and the

proximity to the Sahara make the Nigerian stations hotter than Australian stations

in the dry season, but in the wet season the temperatures more nearly compare

with those of Australia. Another feature which the diagrams bring out is that

the dry season is virtually rainless in Northern Nigeria. Each of the pair of

stations has approximately the same rainfall. The agricultural season has been

defined as the period during which the monthly ratios of rainfall to saturation

deficiency exceed the value of 5, and the very wet season the period during which

the value of 35 is exceeded.

For cultivated crops adapted to seasonal rainfall and capable of high yields,

the agricultural season should probably exceed six months, one month of which

should be very wet in terms of the above ratios. Where the agricultural season

is shorter, crops especially adapted to these conditions are required, the most

important of which will be millets and peanuts.

The data relating to the above-mentioned pairs of stations are summarised

numerically in Table I.

Generally speaking, from the diagrams and from the tables, it will be seen that

for equal rainfalls in the more arid regions the moisture conditions with regard

to both the length of the season and the efficiency of the rainfall are in favour of

Nigeria. The temperatures at Atherton and Herberton do not compare with the

corresponding stations, Zaria and llorin, owing to the position of the Australian

stations on the Atherton tableland.

RELIABILITY OF SEASONAL RAINFALL

A very important factor making for the permanent agricultural occupation

of Nigeria is the reliability of the rainfall, anda comparison between West African

stations and Australian stations is instructive in this respect. Tor this purpose

the rainfall records at a number of selected stations have been examined and the

rainfall for each season determined, winter rains being excluded. In the case of

Katherine the monthly rains were excluded at the beginning and end of the season,

which were below the values required to give a value of 5 to the ratio of rainfall

to the assumed average saturation deficit for the particular month.

The data for a group of stations are given below, the variability of the

seasonal rainfall is expressed as the standard deviation.

Mean Seasonal Rainfall and Standard Deviation (Inches)

AUSTRALIAN STATIONS Wesr AFRICAN STATIONS

Darwin - - - 596 +4 10°3 Bathurst (Gambia) 46°7 + 12-4

Normanton - - 37°04 139 Kano - - - - 344+ 5:5

Wyndham - - 25°06 + 86

Daly Waters - - 24:94 8:7

Hall’s Creek - - 19°44 7:2

236

The variability at Bathurst is seen to be of the same order as in Australia,

for the Nigerian stations the variability is only half that of the Australian stations.

An instructive comparison is available in the two stations Katherine and Kano.

The seasoral rainfall in each case is 34°5 inches, and both are centres for the

cultivation of the peanut. The standard deviation at Katherine over the 65 seasons

from 1872 to 1937 is + 10°44 inches, the effective length of the season has varied

from 3 months to 6 months, with a mean of 4:45 months, while the lowest seasonal

rainfall has been 16°7 inches and the highest 70°7 inches.

Frequency distribution curves of the seasonal rainfall at Kano and Katherine.

Both stations have the same seasonal rainfall, but the proportion of years likely

to receive within 5 inches of the mean is over 70 per cent. for Kano and less than

40 per cent. for Katherine. The differences in the range between the lowest and

the highest likely seasonal rainfall should also be noted.

At Kano, over a period of 17 years, the standard deviation of the seasonal

rainfall has been + 5°48 inches, and the range has been from 26°6 inches to

45°7 inches,

The distributions are sufficiently close to normal to justify a comparison of

the theoretical frequency distribution curves (fig. 3). The essential facts regard-

ing the comparison are well summarised in these curves. Reliability of rainfall

CoNCLUSION

The climate of the greater part of tropical Australia may thus be said to be

characterised by its seasonal character. Any system of agriculture suitable for

this region must seek its counterpart in other parts of the world where such

systems have been developed. West Africa has been selected for comparison as

having a long tradition in this respect and of affording numerous parallels with

respect to soil and climate. ‘The areas suitable for such systems in Australia are

restricted to those of fig. 1 B, in which for some period of the year the monthly

ratio of rairfall to saturation deficit of 35 is exceeded, with a marginal fringe

along the southern boundary. These areas will be seen to be restricted to the

Kimberley coastline, to the northern part of Arnhem [and and its western settled

extension and to the Cape York Peninsula. In these arcas a season of five months’

duration includes one month of very wet conditions, this combination probably

representing the ideal conditions for high yields of most tropical crops adapted to

short seasons.

Apart from these areas, the coastal belt of Queensland should be noted. The

conditions here are entirely different and the length of season is much greater.

‘The map, moreover, reveals the reason for the necessity for irrigating sugar-cane

in the Burdekin delta at Ayr. An important factor which is to be noted is the

great variability of the seasonal rainfall in tropical Australia. No attempt has

heen made to map this variability—examples only have been given. The subject

is suggested as one for further study by a statistician. VF urther limitations to the

scope for agricultural development are likely to be imposed by soil conditions in

these areas. More information is required, however, before any quantitative

assessment of this factor can be attempted.

ABORIGINAL CRAYON DRAWINGS _ III

THE LEGEND OF WATI JULA AND THE KUNKARUNKARA WOMEN

By C. P. Mountrorp, Acting Ethnologist, South Australian Museum

[Read 14 July 1938]

INTRODUCTION

In August, 1935, the author was afforded an opportunity to accompany an

expedition to the Warburton Ranges of Western Australia under the auspices

of the Board of Anthropology of the University of Adelaide, assisted by funds

from the Rockefeller Foundation. ‘These were administered by the National

Research Council.

While stationed at the base camp at Warupuju—a native water on the

junction of the Elder and Warburton Creeks—the writer was able to collect

drawings [vom the aborigines of these parts. Some of these drawings, which

were exected on sheets of brown paper with red, yellow, black and white crayons,

are described below.

As explained in a previous paper (Mountford, 1937C), special care was

taken to avoid influencing the choice of either subject or colour. Until the

aborigines became conversant with the author’s wishes, the only direction given

them was to make zealka (marks) on the paper. In a few days, however, such

a request was not necessary; the natives became so cager to “make marks” that

the author was unable to gather all the relevant information, The supply of

paper and crayons had then to be curtailed accordingly. The significance of the

various symbols and the relevant legends were recorded on a sheet, together with

the registration number of the native and the date. K is the symbol for the

Warburton Range expedition and precedes the number of the particular native.

‘The drawings relate to the wanderings and exploits of the aborigines’

ancestors who inhabited the surrounding country in far-off mythical times. The

aborigine referred to these beings—of which there were many—as tjukur, or

people of the dream time. A suggested parallel of this “dream time” would be

that of the Creation as recorded in Genesis. The drawings obtained were, for

the most part, of a sacred nature, and were not seen by the women, children, or

uninitiated youths. This applies particularly to the suite under review.

In a previous paper (Mountford, 1937C) the author dealt with drawings

which related to the travels and adventures of two ancestral beings, the Wat

Kutjara (IVati—men, Kutjara—two). Those recorded in this paper tcll of a

human ancestor, Wati Jula, and a number of Kunkarunkara women. (Kunka

or Kunkawara—fully developed woman).

Trans. Roy. Suc. S.A., 62, (2), 23 Decemher 1938

242

The Ngada tribe of the Warburton Ranges, amongst whom the members

of the expedition worked, is divided into two divisions, the Tjindulakalngurit

(tjindu—sun, nguru—camp) (literally, those who camp or sit in the sun), and

the Wiltjalanguru (wiltja—shade, nguru—camp) (those who camp in the shade),

(Tindale, 1935, 171). The Watikutjara belong to the anccstral beings of the

former class, and Wati Jula to those of the latter.

According to ‘Tindale, both ancestors came from the cast and travelled

towards the west. The Wati Kutjara passed close to the north of Warupuju,

visiting Telele (Mountford, 1937C, fig. 2), a waterhole some ten miles north-

west. In fig. 7 of this suite, Wati Jula is associated with the same locality.

Similarly, the Wati Kutjara visited Julia in the distant north-cast (Mountford,

1937C, fig. 12). In fig. 3, the man Jula stayed at Kapi Jukata, which was close to

Julia. In fact, the place name Julia suggests some connection with the,

ancestor Jula.

Again, both the Wati Kutjara and Wati Jula possessed a group of women

called the Kunkarunkara; with, however, the distinet difference that whereas the

Wati Kutjara were the protectors of the women (Mountford, 1937C, 20), Jula

seems to have always been their pursuer.

In both cases the ancestors, as well as their women, were transformed into

stars, the Wati Kutjara becoming the Gemini; of which a Gemini is Mumba, the

younger, and 8 Gemini, Kurukadi, the elder.

Jula, on the other hand, is represented in the sky by a series of stars forming

part of Orion; the a and y, i¢., Betelgeux and Belectrix, being the knees, and

Orion’s belt, the toes. Between Jula’s knees are three red stars, which represent

the Kunkarunkara women whom Jula pursued with such pertinacity.

In the interpretation of the drawings, Jula’s women were always referred to

as the Kunkarunkara. Tater on, when discussing the women depicted in the

Wati Jula drawings with Pitawara, our interpreter, he said that, although they

were called the Kunkarunkara, they were not the real Kunkarunkara, but only

resembled them. As the Wati Kutjara were Pitawara’s totem ancestors, it is quite

understandable that he would not consider the women belonging to the ancestral

human being of the other moiety of the tribe—even though they bore a similar

name—to be the same as those of his own totemic being.

The drawings of the Wati Kutjara (Mountford, 1937C) and the Wati Jula

suites have several points in common. In the Wati Kutjara legend Mountford

1(1937C), in fig. 16, depicts an almost identical object constructed and discarded

under similar circumstances by the Wati Jula. Fig. 8 (1937 C) is the mark

made by the dragging of the wanigi by the Wati Kutjara; while fig. 4 of the

present series is almost identical. ‘The Wati Kutjara left two nose bones behind

which turned into hills (see Mountford, 1937 C, fig. 3, R and S). Wati Jula

did the same thing (see fig. 9 of this paper), and two similar natural features

arose. From these comparisons it is evident that each moicty of the tribe has a

248

similar legendary story which relates to the doings of their own particular human

ancestors. In both the Wati Kutjara and Wati Jula legends, the men had women

who bore the same name, and were later transformed into stars; the men also

becatne stars, and both ancestors travelled from east to west, visiting similar

waterholes, all of which lie to the north of W arupuju. In many other ways,

recorded in both the Wati Kutjara and Wati Jula drawings, these people had

adventures in common.

A point worthy of note is the eastward direction of travel of both the Wati

Kutjara, the Wati Jula and the Kunkarunkara. These routes may be those taken

by the first inigrating group of aborigines. Such an aspect requires further study.

DESCRIPTIONS

Fig. 1 illustrates Wati Jula and the Kunkarunkara women (Kunk

young woman) at Kapi Kurubalqua (kapi—water). This was drawn by K 36,

a young aborigine about 20 or more years of age. Six drawings in this suite

Fig. 1

were his work and all referred to the topography and legends of his tribal area.

Wati Jula is shown at A, lying on his abdomen, watching the women prepare their

camp at K. OP, OR and N indicates his arms, legs and head, respectively. A is

now a long hill that resembles Jula’s body. From this place he walked to C, where

he urinated, thereby creating the waterhole Kapi Kurubalqua. Some drops of

Wati Jula’s urine were responsible for the small waterholes at D. B, Jabu Muarlili

(Jabu—hill or rock) was made where the ancestor sat down for a rest. T, and

EF are the hills that rose up where his buttocks and feet rested, respectively.

é er The colours used in this and other drawings of the present series are indicated

on fig. 2.

244

The next stage in Jula’s journeyings was from Jabu Murlili (B) to Jabu

Inbunda (U). The footmarks are indicated at G. At U, the man again rested,

and a similarly shaped hill appeared, U representing the depression made by the

buttocks, and L and M those of the legs.

Wati Jula still had in mind the capturing of the women, and with this object

in view approached them from the direction of their windbreak, J, He was un-

successtul, however; the women, seeing him coming, ran away towards the north-

west, closely pursued by Wati Jula.

A point of interest in connection with fig. 1 is the dissimilarity of the two

symbols, B and U, both of which are used to denote the same thing, /.e¢., the

RED ||

Fig. 2

impression in the sand made by the seated Wati Jula. B, is represented entirely

by rectangles, and U, by more or less circular markings.

Among the Aranda (Mountford, 1937 A, 93), the U within U design has

a similar significance, /.¢., a man’s camp, or where he was seated on the ground.

Fig. 2 was also the work of K 36, and depicts the natural features created

by three animal ancestors, i.c,, Wali Jula, Nurlu, a large mouse (unidentified)

and Nuna, a snake. Starting from the upper hight-hand corner are the tracks,

M, N, of Nurlu, which, judging by those shown at O, is one of the indigenous

marsupials. The animal-being passed through the semi-permanent waterhole,

Kapi Widjul (indicated by the large spiral H), only a short distance north of

our base camp. Continuing on his journey, Nurlu travelled through rock holes,

F and A to R; the former waterholes being named Kapi Ningaru. © indicates

the hind feet and tail tracks of this small ancestral animal, and the small ovals

at G its tracks.

245

Nurlu apparently gave birth to young at R (although the artist did not say

so), for S, 1, V and W are the young Nurlus, which, at the present day are

small hills situated in the middle of a stony plain. R is now a totemic stone that

represents the body of the mother Nurlu. The ground around this place is

tended by the natives of that totem, who erected the wind break P, Q to

assist in keeping the stone clean. R was described as a “pretty stone,” similar

to another totemic stone adjacent to Warupuju. In order to give some idea as

to the probable appearance of R, the wallaby or /awalpa, totemic stone is

illustrated on pl. xili, fig. 1.

Fig. 4

X is a tali, sandhill, Y is a windalka, mulga tree, and W is a semi-permanent

waterhole, Kapi Kaldura, all of which features were the work of the mythical

snake, Nuna.

Ancestral Wati Jula passed through this country; starting at A, Kapi

Ningaru, he travelled to H, Kapi Widjul. His tracks are shown as C. D and F.

While at the latter locality Jula made the waterhole and camped for the night.

Here he constructed a wanigi,“@) which he left at J. It is now a large. stony hill.

Tig. 3 depicts a wanigi made by Jula. The artist, Mungalo (K 14), did

not say whether it is the same as that shown on ,fig. 2. The middle stick T is

made of a spear, on which cross pieces A, B, are fixed. String made of fur is

wound in the manner shown in the drawing. W, X, and Y are the footmarks of

Jula, and V a waterhole, Kapi Jakuka, adjacent to Julia. Fig. 3 is similar

a wanigi.

246

Tig. 4 refers to a large hill, X, called Jabu Wiraruba, situated north-east

of our base camp. I 14, the middle-aged artist, said that Jula came from the

west dragging a wanigi with him (see fig. 3). The broad red line outlined with

white across the centre of fig. 4 signifies the mark made by this object.

Although the significance of Y was not obtained, it no doubt refers to some

part of the topography of the country, probably a deep valley. In fig. 9, Kapi

Wiraruba is again figured, the large hill having, apparently, been created from

a portion of Jula’s genitalia.

Fig. 5 was the work of a young aborigine (K 52), aged about 25, called

Ndanundja. The drawings illustrate some fourteen water catchments in the

country north of Warupuju. Jula entered this territory—indicated on the left of

the page—in company with the Kunkarunkara women. At every place along

the route where the women camped for the night a waterhole appeared, i.c., at

P, O, M, L, Kk, J and I. The parallel lines that connect these places indicate

the ranges of hills that rose up under the feet of Jula as he walked along in

company with the women. Reading from the left, the waterholes are named thus:

P, Kapi Elagudjara; O, Kapi Wunan; M, Kapi Muriga; L, Kapi Murumbal;

Kk, Kapi Jurimba; J, Kapi Kunkarunkara; and I, Kapi Kunjunura. Wati

Jula and the women left these parts in the direction indicated by the arrow. ‘The

meaning of the circles at QO was not given.

The upper group of concentric circles is symbolical of a line of waterholes

ercated by Tjakobari, a mythical emu. Entering this part of the country at I,

a waterhole was created at every camping place, i.e., at H and G, both called Kapi

Ewari; F, Kapi Nurien; E, Kapi Tinkulmungata; D, Kapi Watundja; C, Kapi

Widjul, a place north-west of our camp (see H, fig. 2); and B, Kapi Nulungari.

The parallel lines connecting these localities are hills that rose up from the tracks

of the emu.

247

A comparison between this drawing and that in fig. 2 shows that Kapi Widjul

was created by two ancestors, 7.e., Jula in fig. 2 and the emu Tjakoberi in fig. 5.

As the routes of the wanderings of the totemic ancestors cross the country in

many directions, it is not surprising that more than one totemic group would

claim that some more important waterhole or natural feature was the work. of

their particular forbear.

The particularly decorative sheet, fig. 6, was produced by an aged aborigine,

K 3, named Tolaru. The numerous symbols with which the old man laboriously

filled the sheet represent a number of Kunkarunkara women travelling from

Kapi Lelele, A, B. These waterholes, created by the Kunkarunkara, were situated

some ten miles north-west of Warupuju. The women were all moving toward

the west, carrying their digging sticks, wana, with them. IK 3 was not aware of

their destination, but only knew that in far-off mythical times they had travelled

through the sandhill country north of our camp. The figures, such as C, D, E, F

and so on, are the women who, as they travelled, trailed their digging sticks in

the sandy soil; W, X, Y and Z signify these marks. At F, the details of the

women themselves are shown. S, is the head; [., the body; M, the buttocks;

and K, the hair string bound around their hair. Tolaru made no reference to

Wati Jula. Mountford (1937 C, fig. 2) records a drawing, also the work of K 3,

that relates to one of the Watikutjera at Lelele.

An elderly, one-eyed aborigine named Jandjibalana (K 24) made the draw-

ings of fig. 7, These illustrate a number of waterholes, hills, creeks, and springs

248

made by Wati Jula. The latter is indicated at B. Entering this area in the direc-

tion of the arrow on the lower left-hand corner, the ancestor made C, Karu Wanba

(Raru—creek), In this creek there is good spring water. From there he travelled

through F, G, H, J, K, 5, L, M. He created the large hill N, Jabu Pukuna,

and the three waterholes P, Q, and R. Starting from F, the names of the

localities in which water can be found are: F, Kapi Dudina; D and H are

unnamed, H being only a small catchment; J, Kapi Widjul (see fig. 5); K, Kapi

‘Lyjilida. L, M and P and Q were unnamed, except that Q was specified as a

large waterhole situated in a northerly direction. R was called Kapi Tarkulkura.

The departing tracks of the ancestor appear in the upper right-hand corner at O.

The significance of the groups of concentric circles in the lower part of the

sheet was not obtained, but it is reasonable to suppose that these have a similar

meaning to those already indicated. Wati Jula did not meet anyone whilst in

this locality.

Tig. 8 was drawn by Mungalu (K 14), an elderly aborigine who produced

several unusual drawings, particularly those dealing with the Wati Kutjara

(Mountford, 1937 C, pl. i). In this case the drawing shows the waterholes made

by three beings, t.¢., the Kunkarunkara women, Tjidowri, a snake, and Nirunba,

a small unidentified bird. The bird itself does not appear to have travelled about,

but created the hills R, 5S. G. H, O, J, and C. Q, Kapi Wilkurul, a large rock

hole, is also his handicraft. This ancestral bird lives at the present day in the

249

hills.) Vhe Kunkarunkara created hills D, K and P, but Mungalo, the artist,

was not aware of the women’s destination. A mythical snake, Tjidowri, made

Kapi Kamina, E, and Kapi Ngunduluga, L and M.

Tig. 9 was the work of K 36 and depicts an area of his own tribal country.

Its natural features were created when Wati Jula came across the camp of the

Kunkarunkara women, with whom he wished to co-habit. IJlis advances, how-

ever, were repulsed.

‘The series of small circles at U and W, which are now low rises, are repre-

sentations of the women. A large hill, A, Jabu Wilraburuba, is the transformed

wibu (phallus) of Wati Jula. F are the pubic hairs, and G a hill called Jabu

Wiraruba (see fig. 4).

Some of the symbols shown to the right of A (Jabu Wilraburtuba), in the camp

of the Kunkarunkara, are of intercst. “Phe A-shaped marks at T, superficially

resemble T and W of fig. 1; and, being associated with a camping place, may;

represent a seated aborigine. The semi-circular figures adjacent to U, the enclosed

circles, and the parallel straight lines at X, are somewhat like sketches of camps

@) This particular belief regarding ancestral beings living in waterholes was met

with repeatedly during our work with this tribe. Spencer and Gillen (1904, 252) give

details of an ancestral snake who lived more or less permanently in the waterhole. The

bird menticned in fig. 8 is the first case observed by the author in which an ancestor

still lives in the hills,

made by the natives of these parts. In this case the semi-circular lines represent

the windbreak, the circle within, the woman, and the parallel straight lines, the

sticks of firewood laid in readiness for the evening fires.“ A number of natural

features was created by Wati Jula. R, one of Jula’s camps, is now a large hill.

By the same agency S, Kapi Wunan (see fig. 5), was created. O and Q are hills,

Jabu Ngenga, previously the nose bones left behind by the ancestor.“ D is

recorded as Windulka. This is the aboriginal name for the mulga tree (Acacia

aneuris), but whether D represents such a tree, or is a natural feature bearing

that name, was not ascertained.

While at this place, which is close to a waterhole called Mamai, the ancestral

women played and danced from A to B, the gutters produced in the sand by their

feet forming the spinifex covered flats between the present lines of parallel sand-

hills. The white outer lines of the long rectangles, C in fig. 10, are those flats, and

the inner yellow or black lines, the intervening sandhills.

Ry good fortune, the author, while at Warupuju, witnessed a similar dance

to that performed by the mythical Kunkarunkara women. At the commencement

of the circumcision ceremony the women perform a short dance, nangbi,

in which they move along abreast, shuffling their feet in a peculiar manner (pl. xiii,

fig. 2). The resulting marks made in the sandy soil resemble, in a remarkable

manner, the alternate swales and ridges of the sandhill country. A photograph

of the actual parallel sand ridges“) (pl. xiv, fig. 2), illustrates the similarity

between the tracks of the women and the sandhills,

A similar legend to fig. 10 is connected with fig. 11. In this case the

Wunkarunkara made the hill, A (Jabu Jenabunda), and then danced away back-

ward toward the west. The white lines are the marks made by her feet, now the

crests of fali (sandhills), while the space coloured yellow, i.c., B, C, D, and so on,

around the waterhole, Meitika, situated in the artist’s tribal area.

At this place the ancestral women camped; the series of circles adjacent to

Q indicating the place where they seated themselves. R is a long hill, Jabu Meitika,

that rose out of the ground to form a windbreak for the resting women.

lt was in the bulba (cave), at Meitika, that the ancestral women prepared a

cake by grinding grass seeds. Previous to this the floor of the cave was level,

but since that day a hole exists, worn by the women in their efforts to reduce the

grass seed into flour. This depression is now filled with water, and forms Kapi

Meitika, one of the well-known supplies of the neighbourhood. T is the outline

of the cave. When the women had roade the damper (or cake), they placed it

at N. From notes provided by Mr. N. B. Vindale, it appears that Wati Jula

surprised the women at this place, and was successful in catching one while she

was preparing the cake for cooking. Ie crept towards another sleeping woman,

but, being too eager, slipped and took the skin off his shins. This misfortune

allowed the woman time to escape. Possibly all the women fled at the same time,

for the damper, the bottom grinding stone, and the wooden dish that contained

the grass seed were left at N and D. The grinding stone and dish were trans-

formed into a large hill at the back of Mcitika, the bottom portion being the

grinding stone, the upper the wooden dish, while the damper is now a hill that

slopes downward toward the waterhole.

The women entered this country from the direction of U (lower right-hand

corner) and travelled in a south-easterly direction, V. Various other natural

features are depicted on this sheet. K, M, O, P are hills. 5 is a mulga, and 1. an

unidentified tree called Pulguru. F, G, and Ho are small waterholes, while Ff,

Kapi Purdi. is a large rock hole inside of a cave.

Discussion

The drawings of the Wati Jula legend are somewhat similar in design and

general meaning to those of the Wati Kutjara, and, as in the case of the latter,

the designs, colours used, meaning of the various symbols, and the ages of the

artists, were analysed and fully discussed, no good purpose would he served in

repeating that discussion.

Of the present material, six out of the twelve drawings were the work of

one man, K 36, who was of the Wati Jula totem. The drawings executed by this

aborigine, figs. 1, 2, 3, 9, 10 and 12, most of which relate to his own tribal area,

contain much more detail and interest than those produced by other men, who

were obviously not as conversant either with the legend of Wati Jula or the

topographical features created by him. All the drawings of K 36 referred to

his country, and the doings of his ancestor. It is difficult for the average person

to appreciate an aborigine’s intense interest in and knowledge of his country;

but when we consider that every hill, every creek, every large Uree, every water-

hole is, in the mind of the native, created by semi-human beings who were the

ancestors of his tribe, we can better understand the intimate association between

the native and his country. This understanding and affection for his tribal arca

was strongly exemplified in Pitawara, our interpreter.

254

While on our outward journey we passed through an area of drifting sand-

hills and spinifex-covered flats, which, from the European’s viewpoint, could

hardly be less inviting. Yet Pitawara, turning to one of the members of the!

expedition, remarked, “This good fellow country, this my country.” Here he

pointed out, with obvious pleasure and pride, the creeks made by the Wati

IWutjara, his own forbears, and told us of the doings of his and other ancestral

beings who created the few natural features that the country possessed. To him,

this barren, uninviting area was full of interest because of the adventures and

exploits of the mythical progenitors of his tribe.

A remarkable example of the association in the native’s mind of incidents

of the present day with those of the “dream time” is shown in the legend that

explains the existing parallel lines of sandhills as the marks left in the ground

by the mythical women when they performed the ceremonial dance (see pl. xiv,

figs. 1 and 2). Similarly, in text fig. 12, the likeness of the hill at Mecitika to a

wooden carrying dish resting on the lower grinding stone (a common enough sight

in any native camp), no doubt suggested the first part of the myth. Subsequently,

the other details would be built up concerning the spot, until today we meet the

legend in its present form.

SUMMARY

This paper records twelve crayon drawings that relate the exploits of a

mythical human being, the Wati Jula, and a group of women, the Kunkarunkara.

The similarity between this legend and that of the Wati Kutjara, as recorded

in a previous paper, the aborigine’s relation to his own totemic area and the

possible source of such legends are discussed.

CAMBRIAN AND SUB-CAMBRIAN FORMATIONS AT

PARACHILNA GORGE

By D. MAWSON D.Sc., F.R.S.

Summary

The occurrence at Parachilna Gorge of Cambrian limestone with well preserved Archaeocyathinae

fossils has long been known [Howchin, 1922 and 1925]. In the papers cited, Howchin has accepted

as of Cambrian age a great thickness of beds underlying the fossiliferous Cambrian horizon. The

evidence available appears to indicate that Archaeocyathinae of our beds are indicative of a Lower

Cambrian age. This assignment is in accordance with David's views [Sir Edgeworth David, 1932],

which are based on the findings of Dr. F. W. Whitehouse. As there is in the Flinders Range an

immense thickness of unfossiliferous strata below the Archaeocyathinae horizon, it would appear

probable that such are all Pre-Cambrian with the exception of a very thick arenaceous series which

immediately underlies the Archaeocyathinae — containing limestone series, and with which it

appears to be conformable wherever I have examined it. I am adopting this interpretation, which

seems the most reasonable unless, and until, definite Cambrian fossils are discovered at a lower

horizon. For the present, the beds lying immediately below this quartzite will be referred to as sub-

Cambrian.

CAMBRIAN AND SUB-CAMBRIAN FORMATIONS AT PARACHILNA GORGE

By D. Mawson, D.Sc., F.R.S.

[Read 11 August 1938]

The occurrence at Parachilna Gorge of Cambrian limestone with well-

preserved sirchacocyathinae fossils has long been known {Howchin, 1922 and

1925]. In the papers cited, Howchin has accepted as of Cambrian age a great

thickness of beds underlying the fossiliferous Cambrian horizon. The evidence

available appears to indicate that Archaeocyathinae of our beds are indicative of a

Lower Cambrian age. This assignment is in accordance with David’s views [Sir

Edgeworth David, 1932], which are based on the findings of Dr. IF. W, White-

house. As there is in the Flinders Range an immense thickness of unfossiliferous

strata helow the Archacocyathinae horizon, it would appear probable that such

are all Pre-Cambrian with the exception of a very thick arenaceous series which

immediately underlies the Archacocyathinae-containing limestone series, and with

which it appears to be conformable wherever I have examined it. [ am adopting

this interpretation, which seems the most reasonable unless, and until, definite

Cambrian fossils are discovered at a lower horizon. For the present, the beds

lying immediately below this quartzite will be referred to as stb-Cambrian.

Howebin [1925, 22] states that “no occurrence of fossiliferous Cambrian

age is known to exist between Wilson and Parachilna, a distance of 65 miles.”

Nevertheless, outcrops of Archaeocyathinae limestone do occur over the greater

part of this length. Wherever I have examined outcrops of Archaeocyathinae

limestone in the Flinders Range area, it is found always to overlic with apparent

conformity a great quartzite horizon, which | am accepting as the basal formation

of the Lower Cambrian of South Australia. This is the quartzite of the range

to the west of Wilson, of the Elder Range, of Wilpena Pound, of the Aroona

Range, and of the Chase Range. It is, in fact, the greatest single feature of the

Flinders Range. As this quartzite is responsible for the physiographic feature

known as Wilpena Pound and other pound formations in the Flinders Range,

I propose that it be designated the “Pound Quartzite.” Thus the Pound Quartzite

is accepted as the base of the true Cambrian of the Flinders Range.

I have made many traverses in the Flinders Range establishing the above

contention, but only one, that across the strata at Parachilna Gorge which

illustrates the relation of the beds, is included herewith. Other sections and an

account of the Cambrian and sub-Cambrian beds as far down as the Sturtian

tillite horizon will be published shortly.

Ilowchin [1922] has shown that the Flinders Range in the neighbourhood

of Parachilna Gorge is composed of a thick series of beds arched over Blinman,

which is located in the centre of the Range, and, on either flank, dipping down

steeply beneath the plains bordering Lake Torrens on the west and Lake Frome

on the east. He thus explains the location of Archacocyathinae limestones skirt-

ing the Range on either flank but absent in the central region. However, though

fossils were absent, he regarded all the formations of the central area as Cambrian.

The sections submitted herewith, completed in 1936, traverse the fossiliferous

Cambrian formation on the west flank of the Range and extend some distance

below. The arst section was selected over suitable ground to illustrate the nature

and sequence of the fossiliferous Cambrian beds. The second section is a traverse

across a belt of sub-Cambrian strata lying immediately below the fossiliferous

Cambrian.

Marble, rich in Archaeocyathinae, occupies a limited area at the entrance

to the Gorge. but at that point the succession of the beds is disturbed by faults.

Accordingly, the section of the upper beds, illustrated herewith, was run across

the line of strike (which trends about 10 degrees west of true north) at a point

about a mile north of the Gorge entrance. There the main body of the quartzite

and the overlying limestones are not seriously disturbed by dislocations. How-

ever, in this section the sub-Cambrian beds are badly shattered and dislocated.

Consequently, only the upper portion of these is included ta show general relation-

ship with corresponding beds well tilustrated in the second section.

This second section was run across the strike on an approximately east to

west line at about one mile to the south of the Gorge entrance. Actually, the

castern extremity of the section was close to the Blinman road at a point about

four miles bv road towards Blinman from the Gorge entrance. At this spot the

beds immediately underlying the Pound Quartzite are undisturbed by dislocations

until the eastern limit of the section is reached.

The tabulated data below give details of 54 divisions recorded in the upper

section, and 21 divisions in the lower section. It will be seen that two horizons

of chocolate-coloured tuffaccous shales are recorded in the sub-Cambrian included

within this purview.

In the limestones immediately underlying the Pound Quartzite a band

characterised by what is referred to as micro-cryptozoGn structure, is recorded

in both sections, This is a fine mesh-like fossil or pscudo-fossil structure, which

will be discussed in another publication dealing with algal fossils and pseudo-

fossils of the Cambrian and Pre-Cambrian of the Flinders Range.

A feature of the Pound Quartzite is, that at several horizons in the forma-~

tion the weathered face is studded with nodules as a result of the superior hardness

of the cementing material in clots distributed through the stone. The nodular

or “clot” feature of this quartzite has been observed at widely separated localitics

in the Flinders Range.

The Cambrian calcareous series in this area has been extensively re-

crystallized and partially dolomitised in some places. As a result, the fossil

forms have been largely obliterated. Silicification, usually in irregular patches, is

evidenced in these limestones. Jn one horizon it is in the form of large chert

nodules. Elsewhere, it is in small branching or honeycomb-forms ramifying

through the marble.

258

The upper limit of the Cambrian beds is not reached in this section, being

lost to sight beneath the alluvial accumulations of the plains. The total thickness

of Cambrian strata illustrated amounts to about 3,500 feet of a calcareous forma-

tion, and 1,500 feet of a basal quartzite. This latter, however, is intersected in

its lower portion by crush and faulting, and may, therefore, be short of the true

thickness of the Pound Quartzite.

The sub-Cambrian beds shown are merely a portion of a more extensive

series which stretches away towards Blinman. Included here is a total of about

3,800 feet, which represents only the topmost formations of this series.

STRONGYLE NEMATODES FROM CENTRAL AUSTRALIAN

KANGAROOS AND WALLABIES

By T. HARVEY JOHNSTON and P. M. MAWSON, University of Adelaide

Summary

The senior author took the opportunity, whilst accompanying anthropological expeditions to Central

Australia between 1928 and 1936, to examine for the presence of parasites many of the larger

marsupials shot in order to supply meat for the aborigines assembled at the various camping places.

Generally, only the stomach was searched because of the lack of time and the prevalence of very

persistent muscid flies. In those cases where the intestine was examined, nematodes were not found

in it. This accounts for the absence of trichostrongyles amongst the material studied. In spite of the

long periods of dry weather and the low rainfall of the regions visited, the very heavy infestation of

nearly all stomachs examined was remarkable. No doubt the scanty soil in the vicinity of the few

springs and rockholes becomes heavily contaminated with eggs and larvae. The great number of

different species and of individual worms to be found reminds one of similar conditions often

encountered in the digestive tract of other herbivores such as the horse, ox, sheep, elephant, etc.

STRONGYLE NEMATODES FROM CENTRAL AUSTRALIAN

KANGAROOS AND WALLABIES

By T, Harvey Jounston and P, M. Mawson, University of Adelaide

[Read 11 August 1938]

The senior author took the opportunity, whilst accompanying anthropological

expeditions to Central Australia between 1928 and 1936, to examine for the

presence of parasites many of the larger marsupials shot in order to supply meat

for the aborigines assembled at the various canrping places. Generally, only the

stomach was searched because of the lack of time and the prevalence of very

persistent muscid flics. In those cases where the intestine was examined, nema-

todes were not found in it. This accounts for the absence of trichostrongyles

amongst the material studied. In spite of the long periods of dry weather and

the low rainfall of the regions visited, the very heavy infestation of nearly all

stomachs examined was remarkable. No doubt the scanty soil in the vicinity of

the few springs and rockholes becomes heavily contaminated with eggs and

larvae. The great number of different species and of individual worms to be

found reminds one of similar conditions often encountered in the digestive tract

of other herbivores such as the horse, ox, sheep, elephant, ete.

The iwo main animals searched were the rock wallaby, Petrogale lateralis

Gould, which has a wide distribution in Central Australia and adjacent parts of

South Australia, though restricted to the very rocky areas; and the curo,

Macropus robustus Gould, occupying the less rocky parts of the hilly country in the

same regions. The local subspecies was M. r. erubescens Sclater. Occasionally

a kangaroo. Macropus rufus, Desm., was taken on the great plains. We have

included in our examination some material from M. isabellinus Gould, a species

(or perhaps a subspecies of M. robustus) inhabiting a part of North-western

Australia, the actual host specimens having died in Sydney Zoological Gardens,

the material having been received through the kindness of the Director, Mr.

A. S. Le Souef.

The localities mentioned in this paper are Mount Licbig, now included in the

northern partion of the Aboriginal Reserve in Central Australia; Cockatoo Creek,

lying further to the northward; Ilermannsburg, in the Macdonnell Ranges; also

the following localities in northern South Australia: Ernabella in the Musgrave

Ranges, and Nepabunna in the northern Flinders Ranges. The types of all new

species described in this paper have been deposited in the South Australian

Muscum.

Labiostrongylus longispicularis Wood; L. petrogale.

Cloacina minor; C, parva; C. macropodis; C. petrogale; C. hydriformis;

C. ernabella; C. elegans.

Unless otherwise indicated, all species of nematodes mentioned above are

considered new. The absence of species of Macropostrongylus and the abundance

of species and individuals of the related genus Cloacina are noteworthy.

Pharyngostrongylus was found only in rock wallabies (Petrogale). Labio-

strongvlus was represented in all host species examined.

Of the species found in Macropus robustus, Cloacina minor, C. parva and

C. communis were by far the most common; C. frequens and C. macropodis very

common ; C. australis, C. magna and C. curia not uncommon; C. dubia was recog-

nised only once; and a few Labiostrongyles were found in nearly all examinations.

Only one stomach from Macropus rufus from Central Australia was searched,

most of the parasites being species of Cleacina, but worms obtained many years

ago from a red kangaroo from the western plains of New South Wales were

identified as L. longispicularis, as also were worms from Macropus isabellinus

from North-western Australia.

The commonest parasites of the stomach of Petrogale lateralis were Cloacina

manor, C. parva, C. petrogale, C. hydriformis, Pharyngostrongylus alpha, P. beta,

and Labiostrongylus petrogale, C. ernabella was fairly common. The remainder

were much less frequently met with.

All parasites described in this paper were collected from the stomach.

Pharyngostrongylus alpha n. sp.

Figs. 1-5

Host—Petrogale lateralis, Mount Licbig.

Short, thin, 6-7°5 mm. long in both sexes. Cuticle with very fine striations.

Anterior end with six small rounded papillae, inwardly from these are six rounded

inner lips surrounding narrow mouth, 5 diameter. A short passage, 7 » long,

with slightly chitinised walls, leads into a vestibule, 0-04 mm. long, 0-012 mm.

wide, with strongly chitinised striated walls. Ocsophagus differentiated as in

succeeding species. Excretory pore behind nerve ring and lying at junction of the

two oesophageal regions. Cervical papillae thread-like; about 0°12 mm. from

anterior end. Anterior end of intestine with thick sacculate walls.

265

Male—Ventral lobes of bursa quite separated from each other and almost so

from the long lateral lobes; dorsal lobe well defined with slight median cleft.

Inside wall of bursa with small rough papillae of various sizes, very small on

dorsal and ventral lobes, largest near bursal edge, most abundant on lateral lobes.

Ventral rays close together, parallel, passing into apex of ventral lobes; externo-

lateral short like externo-dorsal, both forming projections on lateral wall of

bursa; lateral rays run together to bursal edge in longest part of lobe; externo-

dorsal arises separately; dorsal ray bifurcates just beyond half its length, each

part giving rise to a short lateral branch, none of these branches reaching bursal

edge, Genital cone, small, rounded; accessory cone with two finger-like processes

on each side; spicules 1-36 mm. long, straight, with striated alae extending for

almost their whole length, tips curved; gubernaculum heart-shaped when viewed

dorsally.

Female—Uteri parallel, joining near vulva; vagina straight, rather short

and, except in very young specimens, projects through vulva and sometimes is

rolled back like a cuff. Anus 0°3 mm. and vulva 0-082 mm. from tip of thin tail.

266

This species differs from P. beta in the characters of the head, position of

excretory pore, relative length of oesophagus and of spicules, and in total length

of body. It resembles P. australis in many features, but differs in dimensions of

vestibule and in possessing no leaf crown. Neither Wood nor Monnig noted the

presence of an accessory genital cone, and the continuation of the dorsal ray noted

by them was not observed in the present species.

Pharyngostrongylus beta n. sp.

Figs. 6-8

Host—Petrogale lateralis, Mount Liebig.

Short, thin, more or Iess straight when preserved. Male, 3-9-5 mim.; female,

7-8 mm. long. Cuticle very finely striated. Mouth collar with six small papillae,

each with an antero-lateral projecting portion, bearing a delicate process 7 » long.

Inwardly from the collar arises the smooth dome-like anterior extremity surround-

ing the circular mouth. No leaf crown. Buccal capsule 18 in diameter, 9p in

length, with chitinous ring at its base. Vestibule about 0-04 mm. long in young

specimens, with annulate chitinous wall. Oesophagus long, narrow, with longer

anterior region and shorter narrower posterior portion widening into a bulb before

joining intestine. Cervical papillae bristle-like, about 0-08 mm. (in young

specimens) from anterior end. Excretory pore just anterior to junction of the

two regions of oesophagus. Nerve-ring just in front of level of excretory pore.

Male—Inside of bursa with numerous, very small, papillae, fewer and smaller

on dorsal lobe. All lobes separated by deep clefts; dorsal lobe with short median

cleft. Externo-lateral and externo-dorsal rays give rise each to a lateral projec-

tion on bursa. Medio- and postero-laterals extend almost to edge of bursa.

Dorsal ray bifureates just beyond half its length, each part giving off a shorter

lateral branch; no part of dorsal ray reaches edge of bursa. Genital cone short;

accessory cone with two finger-like projections. Spicules straight, 1-4 mm. long,

with striated alae and curved tips. Gubernaculum not seen.

Female—Uteri parallel ; vagina straight; distance from vulva to anus about

equal to that from anus to tip of tail. Body narrows from level of vulva to form

a thin tail.

P. beta differs from all described species in the absence of a leaf crown

and in the character of the head papillae. The anterior end suggests that of

P. australis in general form, but the latter has a narrower vestibule and its anus

and vulva are much nearer to each other. The oesophagus and dorsal ray of the

bursa resemble those of P. brevis, but the new species differs from the latter in

having longer spicules, papillae on the bursa and in the absence of a leaf crown.

Labiostrongylus macropodis n. sp.

Figs. 9-14

Host—Macropus robustus, Mount Liebig, Cockatoo Creck.

Males, 21-30 mm. long; females, 24:8-31-2 mm. Maximum breadth, 1-1 mm,

Long stout worms with anterior end prolonged into eight lip-like processes—four

267

of them large bilobed submedian, two rather shorter simple lateral, one short

simple dorsal, and one short simple ventral. Each submedian with long conical

papilla, each lateral with small rounded papilla. Buccal capsule 0°08 mm. long,

0-15 mm. wide, lined by cuticle. Oesophagus long, about one-fifth body length,

straight. Anterior end of intestine surrounded by granular mass forming two

pairs of lateral lobes. Nerve-ring at about 1 mm, from anterior end, and just in

front of excretory pore. Cervical papillae not observed.

Male—Spicules long thin striated, sometimes much curved, 9°4-11:1 mm.

long, about 1-2°5 of body length. Bursa large, lobes well differentiated, ventral

lobes separate. Ventral rays reach almost to bursal edge. Externo-lateral rays

short, close to medio-latcrals; medio- and postcro-laterals long, reaching almost

to bursal elee; externo-dorsal arises from same root as laterals, is thick, inter-

mediate in length between medio- and externo-laterals. Dorsal ray relatively

narrow, dividing at about half length, each branch terminating in two short

rounded processes reaching almost to bursal edge.

Female—Uteri parallel, uniting at some distance from vulva; ovejectors

0-8 mm. long; vagina 3 mm., narrow. Anus about midway (0°94 mm.) between

vulva and tip of tail. Tail long, narrow, tapering, with rounded extremity.

The species differs from L. labiostrongylus and L. longispicularis in dimen-

sions, structure of the dorsal ray, and length of spicules.

LABIOSTRONGYLUS LONGISPICULARIS Wood 1929

Figs. 15-17

Wood’s unfigured account was based on a male specimen from Mecropus

robustus var. woodwardi, a race living in the Murchison district of Western

Australia. Our material was taken from J. robustus var. erubescens, from

Nepabunna, Northern Flinders Ranges, South Australia.

Long stout worms; male, 4-4 cm.; female, 5°6 cm.; slightly tapering

anteriorly, Six lips, four submedian, two lateral, submedian lips broadened,

slightly bifurcated at tips and bending inwards over mouth; each submedian with

short bristle just behind its midregion; each lateral with small rounded papilla

near tip; no leaf crown. Buccal capsule 0-115 mm. long in male, slightly longer

than broad, walls thinly chitinised, cavity as wide anteriorly as posteriorly.

Oesophagus 8-7 mm. long in male, 9 mm. in female (1:3 and 1:6°2 of body

length respectively), narrow, without definite bulb, though wider near base than

anteriorly. Nerve cord about 1°6 mm. from anterior end; excretory pore about

2mm, from head end. Cervical papillae not observed.

Afale—Bursa stout, lobes definite, ventral lobes distinct from laterals and

separated from each other ventrally. Ventral rays parallel, arising near laterals

but soon bending ventrally to the corner of corresponding ventral lobe, Ventro-

lateral ray short, bending outwards to form slight projection (5) on side of

bursa. Medio- and postero-laterals much longer, travel together, the correspond-

ing part of the lateral lobe forming a horn-like projection when seen dorsally or

ventrally. Externo-dorsal ray short, ariscs with laterals, and projects like the

ventro-lateral. Dorsal lobe separated from lateral by deep fissure. Dorsal ray very

stout, giving off a lateral branch on each side midway from its origin, the branch

extending almost to bursal edge at lateral termination of dorsal lobe; main ray

divides into two parallel branches. Dorsal lobe long, its posterior edge forming

two or three lappets, the two outer (which contain the ends of the dorsal ray)

rounded; between these may he a third more or less devcloped, sometimes con-

taining an abortive median continuation of dorsal ray. Genital cone short, conical

with small button-like papilla at tip. Accessory cone wider, not quite so long,

with several elongate processes laterally. Spicules 17-8 mm. long (1:2°5 of body

length), stout, fairly straight, striated, with striated alae.

Female—Uteri joint about 3:8 mm. from vulva; vagina narrow, coiled; anus

1-4 mm. from tip of short narrow pointed tail; vulva 2-5 mm. from tip of tail.

A male Labtostrongylus was found in the stomach of a rock wallaby,

Petrogale lateralis, {rom Mount Liebig, Central Australia, agreeing in its head

characters with L, longispicularis, The position of the nerve cord was similar,

but the excretory pore was posterior to the oesophagus instead of being near the

nerve-ring, the oesophagus was about one-seventh of the body length, and the

spicules 1: 5-6 of body length instead of 1:2°5. The specimen was only 24 mm.

long. The bursa was asymmetrical and the dorsal ray differed somewhat from

that described above.

269

As there was only one specimen available, we deem it unwise to erect a new

species for it. It seems to be most closely related to L. longispicularis.

A number of specimens taken from Macropus rufus from western New

South Wales and from M. isabellinus (which is probably a variety of M. robustus)

from North-western Australia (from Sydney Zoological Gardens) also belong

to L. longispicularis.

Labiostrongylus grandis n. sp.

ventral. shorter than submedians. Laterals, ventral and dorsal lips simple, conical.

Submedian and lateral lips cach with papilla, conical on submedians, small and

rounded on laterals. Apparently small rounded papillae about 0-2 mm. from

anterior end, two of them lateral and perhaps one ventral and one dorsal. Cervical

papillae long, thread-like, arising from cuticular depression 1-1 mm. from anterior

end. Buccal capsule shallow, 0°12 mm. wide, with chitinised portion 0°08 mm.

long; from tip of lips to floor of capsule 0°15 mm. Nerve-ring 1-3 mm. and

excretory pore 1:8 mm. from anterior end. Ocsophagus long, straight,

0-8-0'9 mm. (one-fifth body length) in male, one-sixth in case of female.

270

Male—Bursa with well-defined dorsal, lateral and ventral lobes; ventrals

quite separated from each other and smaller than laterals. Ventral rays equal,

parallel. Externo-laterals, laterals and externo-dorsals arise from same root, the

first shortest, the other two reaching nearly to bursal edge. In posterior view of

bursa externo-lateral and externo-dorsal rays appear to form projections on

lateral walls. Dorsal ray stout, bifurcating at beginning of second half of its

length, each branch subdividing at half its length into an inner club-shaped and

an outer short ray, neither reaching bursal edge. Spicules 12-4 mm. long, 1: 3-3

of body length, fairly straight, striated, with alae extending nearly to the rounded

tips. Accessory genital cone not observed.

Female—Body narrows suddenly after vulva; tail long, thin, with rounded

end bearing two small lateral subterminal papillae, 0-2 mm. from tip. Vulva

2°6 mm. from posterior end. Uteri wide but narrowing greatly into ovejectors

just before the two join about 4 mm. from vulva; vagina narrow, twisted, Eggs,

0-145 by 0-11 mm.

The species differs from L. labiostrongylus in its spicules; from L longi-

Sspicularis in its lips; and from other species in the structure of the dorsal ray.

Labiostrongylus petrogale n. sp.

Figs, 21-22

From Petrogale lateralis, Mount Liebig. Male up to 4:4 cm., female up to

6 cm. Four submedian lip-like prolongations bilobed at distal end, almost meet-

ing over buccal capsule. Lateral lips shorter, conical, with small rounded papilla

near tip; submedian lips each with thin pointed papilla arising from slight bulbous

cuticular enlargement. No dorsal or ventral lips. Buceal capsule with thick

chilinous lining (0°11 mm. long) continuous at its base with lining of ocsophagus ;

floor of capsule 0-195 mm. from anterior end of lips. Oesophagus 6°66 mm.

long in male, te., one-sixth body length, narrow, surrounded by mass of dark

cells at junction with intestine. Cervical papillae thin, about midway between

nerve-ring and anterior end. Nerve-ring and excretory pore at about level of

end of first quarter of oesophagus.

Male—Bursa large; ventral lobes separated from each other, distinctly

marked off from laterals; dorsal lobe with short median cleft. Ventral rays long,

parallel, reaching bursal edge. Externo-lateral shorter than laterals, which extend

almost to edge and are cleft for nearly half length; externo-dorsal thick, arises

with laterals, and longer than externo-laterals. Dorsal ray very thick, bifurcat-

ing at two-thirds length, each branch giving off a lateral, all final branches

slightly bulbous and extending almost to bursal edge. Genital cone long, conical ;

accessory cone with two short thick processes, each ending in one or two finger-

like projections. Spicules about 7°25 mm., i.¢., one-fourth to one-sixth body

length, curved, with striated alae along most of length. Gubernaculum present.

Female—About 0-2 mm. in maximum diameter. Anus about midway

between vulva and tip of tail; latter rather short, tapering, with rounded end

terminating in button-like structure. Vagina long, narrow, twisted.

271

The species resembles 1. longispicularis in its head region, but differs in the

length of spicules and the character of the dorsal ray.

Croacina Linstow (emend.)

Linstow's original diagnosis (1898, 287) indicated that the genus ditfered

from all known nematode genera in having the vulva and anus united into a

female cloaca. Railliet and Henry (Bull. Soc. Path. exot., 6, 1913, 506) stated

that the two apertures were distinct and that the genus was synonymous with

Zoniolaimus. York and Maplestone (1926) gave a much more satisfactory

diagnosis based on Linstow’s account and figures of the type C. dali, as also did

Baylis and Daubney (1926). The original material came from Macropus brownt

Ramsay, from Ralum, New Britain. The genus has been placed in Strongylidae ;

Cloacininac; Cloacinidac; Trichoneminae; and amongst the Strongyloidea “in-

sufficiently known.”

Amongst our material from Australian marsupials we have found numerous

species which we have been able to assign to Linstow’s genus as amended by us.

A revised diagnosis is now given.

Trichoneminac—Mouth directed straight forwards. Mouth collar with

6-8 lips, four of them submedian and two lateral, with in some cases a dorsal

and a ventral: each submedian lip with a prominent papilla; on lateral lips usually

an insignificant papilla. Buccal capsule cylindrical, broader than long; leaf crown

of six elements arising from its internal surface and projecting through mouth

opening. Ocesophagus with more or less developed swelling at its posterior end.

Male—Well developed bursa; ventral lobes joined in front; ventral rays cleft

distally ; externo-dorsal may or may not arise with laterals, medio- and postero-

laterals lying side by side; dorsal ray bifurcates after an half to one-third of its

length, and the two branches subdivide further back. Spicules usually long, thin,

with striated alac. Gubernaculium present or absent.

Female—Body tapering behind vulva; tail usually pointed; distance between

vulva and anus usually about equal to that between anus and tip of tail, Uteri

parallel,

Parasites of the stomach of marsupials. Type C. dahli Linstow.

he chief distinctions between this genus and Macropostrongylus are the

presence of lips and the relative sizes of the lateral and submedian papillae.

rays thin, straight, almost reaching bursal edge; externo-lateral and externo-

dorsal project slightly on lateral wall of bursa; laterals long, slender, almost reach-

ing edge. Dorsal ray stout, soon dividing, each branch passing postero-laterally

DATA SHOWING RATE OF DEVELOPMENT OF

TRUNK OF TREE FERN

On 15th November, 1921, close to the foot of Mount Dandenong, Victoria,

in company with Mr. A. G. Campbell, of Kilsyth, Victoria, I collected a young

tree fern, Alsophylla australis, which I brought back and planted in my “brush

house” at Blackwood. The tree was found in swampy ground and had a few

fronds of only slightly over 3 inches in length.

In November, 1937, the following measurements of this specimen were

obtained :

Trunk: Circumference at ground level, 33 inches; at 3 feet above ground,

28 inches; at one foot from crown, 27 inches; height from base to crown,

51 inches.

Fronds: One of the larger ones, 7 feet 3 inches long; thus, when fully

expanded, the expanse was nearly 14 feet.

Average annual growth, 34 inches.

L INTRODUCTION

The above bore was sunk on the ground of the Metropolitan Abattoirs

Works, situated six miles in a direct line, north by cast direction, from the

Adelaide Post Office, and rather more than a mile from the Dry Creek Junction,

As the sediments passed through proved, at certain levels, very fossiliferous,

the Museum and University authoritics undertook jointly to secure and bring

to Adelaide a drayload of the fossiliferous material for detailed examination.

The late Sir Joseph Verco and the senior author spent some time together in

passing the loose sandy material through sieves and collecting the fossils so

separated,

It was agreed between Sir Joseph and the senior author that the former

should deal with the Mollusca and that the geological features, together with the

foraminifera and other fossils, should be described by the latter. It became a

matter of deep regret that in consequence of ill-health Sir Joseph had to relinquish

this work, but he generously placed his notes on the fossils he had examined at

the disposal of Miss N. H. Woods, M.A. (now Mrs, Ludbrook), who had pub-

@) This paper was begun by the senior author, but, owing to his death, was not

completed by him. The plates, with the exception of two or three figures, had been drawn

and most of the paper up to the end of the section dealing with the Upper Pliocene

foraminifera had been written. At the request of the Director of the South Australian

Museum, to which the late Professor Howchin bequeathed his collection ot fossils,

Mr. Parr undertook the completion of the paper. In doing so, he has revised, as far as

possible, the earlier determinations and utilized Professor Howchin's notes, and accepts

joint responsibility for the work.—-Epiror.

lished some original observations in the determination of new species in the

Transactions of this Society.

It is unfortunate that a scientific examination was not made during the

course of the boring operations, but the main geological horizons are so well

defined lithologically and palaeontologically that it is an easy matter to classify

the section into three main geological ages.

Phe thanks of the authors are due to J. H. Horwood & Co. Ltd, the con-

tractors who carried out the work at the Abattoirs Bore, and especially to Mr.

W. J. Barker, Managing Director of the company, who in response to the senior

author’s request, courteously supplied the boring log which follows.

IlI STRATIGRAPHICAL DIVISIONS

Section 1. Recent to PueisroceNe: From surface to 341 ft. Alluvial

sand and gravel, some very coarse, representing the superficial deposits of the

Adelaide Plains.

Section 2. Upper Priocrne: From 341 to 500 ft. Mostly a clean white sand

with a shallow-water marine fauna, generally of Recent aspect. It was from

this horizon that the large quantity of material to which reference has been made

was obtained.

Section 3 Mtocene: From 500 to 820 ft. (bottom of bore). Geologically

uncomformably related to the overlying sediments, carrying a distinctive fauna

which is comparable with that of the lower portion of the Miocene of Victoria.

‘Two horizons are represented in the material examined, the upper, between 575

and 620 feet, and the lower, which carries a number of species characteristic of

the Lower Miocene of Batesford and Muddy Creek, in Victoria, between 710 and

820 feet.

The geological section revealed in the present bore agrees essentially with

others which have been obtained by borings within the great Adelaide sunken

basin, antecedently described in the Dry Creek and Croydon Bores, and, lately,

from the Brooklyn Park, Glanville, and Cowandilla Bores (Ilowchin, 1935 and

1936), in which the geological features of the group have been under discussion.

Note—The senior author has previously recognised a geological stage of Upper

Pliocene age, in the Adelaide Basin, to which he gave the name of Adelaidean. This

consists of fussiliferous marine beds occupying a limited area along the western and north-

eastern sides of the city of Adelaide, following the direction of: Cowandilla, Brooklyn

Park, Lockleys, Croydon, Glanville, the Metropolitan Abattoirs, Dry Creek, and Salisbury.

The occurrence of these beds in the Brooklyn, Glanville, and Cowandilla Bores is dealt

with at length and an explanation of their origin given in Professor Howchin’s' papers

published in the Transactions of this Society for 1935 and 1936. The beds now recorded

from the Abattoirs Bore as of Upper Pliocene age belong to, the same stage.

Mrs. N. H. Ludbrook, M.A. (née Woods), who has examined the pelecypods irom

the Abattoirs Bore and the mollusca of the Hindmarsh Bore, recently (Rept. A.N.Z.

Ass. Adv. Sci., 1937 Meeting, pp. 444-446) expressed the view that the beds assigned by

Howchin to the Upper Pliocene (Adelaidean) are all of Lower Phocene (Kalimnan) age.

She states: “In no case are the “Adelaidcan’ beds proved either to underlic or overlic

the Lower Pliocene, though Howchin (1936) has suggested that they may overlie the

Lower Pliocene in the Cowandilla Bore. Accumulation of evidence made possible by

the extensive boring operations in search of water in the neighbourhood of Adelaide during

recent years has shown that faulting has taken place on a large scale, details of which it

is hoped will be available in the future; it is no longer completely improbable that such

faulting could account for the position of the ‘Adelaidean’ beds, while they may be

synchronous with other beds of Lower Vliocene age in Southern Australia, Further-

more, it is suggested that sufficient attention must be given to the change in the fauna,

due to varying conditions, at different localities along a coastline; this can be demon-

strated along any coastline today.”

On the evidence of the foraminifera and with knowledge of ‘the foraminiferal

faunules occurring in the Lower Pliocene (Kalimnan) at Kalimna, and at McDonald’s

and Forsyth’s, near Hamilton, in Victoria, I am in agreement with Professor Tlowchin’s

reference of the upper marine beds of the Abattoirs Bore to the Upper Pliocene, It

might be suggested, as Mrs. Ludbrook has done in regard to the mollusca, that facies

290

may account for the differences between the assemblage of foraminifera in the Abattoirs

Bore and those of the Victorian Kalimnan localities. This does not, however, appear

a satisfactory explanation, as the beds at the Victorian localities mentioned are all shallow-

water, more or less sandy clays and facies alone would not account for the differences

between the foraminifera of the present bore and those of the Victorian localities. The

Victorian beds contain certain restricted species such as Flintina intermedia (Howchin),

which occurs at Kalimna as well as in the Hamilton district and elsewhere, and Mabularia

howehini Schl, (Hamilton district only), and the assemblages otherwise differ in many

respects from that in the Abattoirs Bore. On the other hand, we have in the Bore very

distinctive forms such as I’lintina triquetra (Brady) and Nubecularia lucifuga Detr., var

lapidea Wiesner, which have not been previously recorded fossil and have not been met

with in the Kalimnan of Victoria. The presence of several genera of the family

Peneroplidae also gives the faunule a strong Recent aspect. Still further evidence is:

provided by the record by Professor Howchin of the occurrence, in the Adelaidean of the

Brooklyn Park, Glanville, and Cowandilla Bores, of Cribrobulimina polystoma (BP. & J.),

hitherto known only from the Pleistocene and Recent seas of southern Australia.

Mr. F. Chapman has informed me that he is also in agreement with Professor

Howchin’s opinion that the Adelaidean beds are younger than Kalimnan. He has kindly

furnished the following note.

“The Adclaidean series of the Abattoirs and Hindmarsh Bores show a molluscan

fauna similar to that of Hallett's Cove, largely of a Recent aspect and with such

older species as Neodiastoma provisi (Tate) (not Kalimnan). The Eucrassatellae I

examined for Howchin were not in every case typical of the Kalimnan forms, many

showing annectant characters between the Upper Muddy Creek and the Jemmy’'s

Point, Kalimna, forms, whilst others again were non-typical of cither.

“In the present case the position in the vertical scale appears to be better

indicated by the comprehensive series of the foraminifera, which comprise so many

species new to the Kalimnan of the type locality and the Muddy Creek area.”

It will be noted that Mr, Chapman disagrees with Professor Howchin’s reference

(1935, p. 85) of the Hallett’s Cove beds to the Kalimnan.

In the Abattoirs Bore no beds of Kalimnan age have been recognised. [t is possible

that they may be represented between 500 and 575 feet, but fossil evidence on this point

is lacking, the foraminifera examined coming from between 341 and 500 feet and irom

575 feet downwards, : W. J. P.

Clavulina pacifica Cushman, 1924, p. 22, pl. vi, figs. 7-11; 1937, p. 25, pl. ut,

figs. 17, 18.

This species was described irom Pago Pago Harbour, Samoa, and is well

distributed through the warmer portions of the Indo-Pacific region in shallow

water. It has not been previously recorded as a fossil. Australian Recent

occurrences are at Murray Island, Torres Strait, Port Denison, Queensland, and

Geraldton Harbour, Western Australia. It is rare in the Abattoirs and Cowandilla

Bores.

C. difformis Brady Cushman, 1921, p. 156, pl. xxxi, figs. 2 a, b; 1937, p. 23,

pl. iii, figs. 4-10.

Like the preceding species, this is widely distributed as a living form in the

Indo-Pacific region and is frequently associated with C. pacifica. lt may be

distinguished from C. pacifica by its coarse-textured shell-wall; the test is also

polygonal in transverse section, while that of C. pacifica is triangular. There is

one example, not quite perfect but otherwise typical, from the present bore. The

junior author has Recent specimens from the coast of Victoria.

CLAVULINA MULTICAMERATA Chapman

Clavulina parisiensis d’Orbigny var. multicamerata Chapman, 1909, p. 127,

C. multicamerata Chapman: Parr, 1932, p. 4, pl. i, figs. 4, 5. Cushman, 1937,

p. 24, pl. ili, figs. 13-16.

This was described by Chapman from Shoreham, Westernport, Victoria,

as a varicty of C. parisiensis, and was later given specific rank by Parr. It is

common in shallow water on the southern coast of Australia, and also occurs as

a fossil in the Upper Beds (of Lower Pliocene age) at Muddy Creek, Victoria.

Verco dredged some fine examples off the Neptune Islands (South Australia).

In the Abattoirs Bore the species is moderately common. A noteworthy feature

is that some of the specimens are limited to the triserial portion of the test, when,

but for the presence of the adult form, they would be referred to the genus

Valuulina. The figured specimen is a slender, delicate one, the remainder being

perfectly typical.

Family MILIOLIDAT

Genus QuringueLocuLtna d’Orbigny, 1826

QUINQUELOCULINA AGGLUTINANS d’Orbigny

(PL xv, fig. 1)

Ouinqueloculina aggliutinans d’Orbigny, 1839, p. 195, pl. xii, figs. 11-13, Cushman,

1929, p. 22, pl. i, figs. 1 a-c.

This species is represented by four very typical examples, one of which

measures 1:7 mm. in length. It is a common form in shallow water in the West

Indian region.

QUINQUELOCULINA AMMOPHILA Parr

(Pl. xv, figs. 3, 4)

Quingucloculina ammophila Parr, 1932, p. 8, pl. i, figs. 10 a, b; text fig. 1 E.

Chapman and Parr, 1935, p. 3.

There are five examples of this species which was described from shallow

water in Westernport Bay, Victoria. Like Q. agglutinans, the test is coarsely

292

arenaceous, but it is much compressed, with strongly depressed sutures, and the

aperturs has a single plate-like tooth, so it may readily be distinguished from the

older species.

QUINQUELOCULINA SEMINULUM (Linné)

Serpula seminulum Linné, 1767, p. 1,264.

Quingueloculina seminulum (Linné): Cushman, 1929, p. 24, pl. ii, figs. 1, 2.

This is represented by a few fine examples.

QUINQUELOCULINA vuLcaris d’Orbigny

Quingueloculina vulgaris d’Orbigny, 1826, p. 302, No. 33. Schlumberger, 1893,

p. 207, text figs. 13, 14; pl. ii, figs. 65, 66, Cushman, 1929, p. 25, pl. ii,

figs. 3 a-c.

This is closely related to the previous species but is more rotund in outline,

being about as wide as long and with well-defined sutures. It is rather scarce in

the bore, but is a common form in Recent shore sands from Victoria and South

Australia.

QUINQUELOCULINA BoscIANA d’Orbigny

(Pl. xv, fig. 15)

Quinqueloculina bosctana d’Orbigny, 1839, p. 191, pl. xi, figs. 22-24.

Miliolina bosciana (d’Orb.): Chapman, 1900, p. 177, pl. i, fig. 7.

‘The test of this species is comparatively long and narrow, as in Triloculina

oblonga, but the chambers are arranged on a quinqueloculine plan and the sutures

are oblique. The types were from shore sand, Cuba, and it is common on the

Victorian coast. The three examples from the Abattoirs Bore are typical.

QUINQUELOCULINA LAMARCKIANA d’Orbigny

Quingueloculina lamarckiana d@’Orbigny, 1839, p. 189, pl. xi, figs. 14, 15.

Cushman, 1929, p. 26, pl. 11, figs. 6 a-e.

The present specimens are not typical, being intermediate between this species

and Q. vulgaris, but are nearer the former. In its typical form, QO. lamarckiana

has the chambers triangular in transverse section, the margins to the test being

subacute. The bore examples are poorly developed and have much blunter angles.

The two forms occur together in shallow water on the coasts of South Australia

and Victoria.

QUINQUELOCULINA POLYGONA d’Orbigny

(Pl. xvi, fig. 14)

Quinqueloculina polygona d’Orbigny, 1839, p. 198, pl. xii, figs. 21-23. Cushman,

1929, p. 28, pl. iii, figs. 5 a-c; 1932, p. 25, pl. vi, figs. 5, 6.

This species is common in the bore material, the examples being similar in

form to that figured by Cushman from off Levuka, Fiji (1932, loc. cit., fig. 6).

The types were from the West Indies and the species is common in the tropical

Pacific and also on the southern coast of Australia, in shallow water.

293

QUINQUELOCULINA LIMBATA d’Orbigny

Quingueloculina limbata d’Orbigny, 1826, p. 302, No. 20. Fornasini, 1905,

p. 66, pl. iti, fig. 9.

Miliolina limbata (d’Orb.): Wiesner, 1923, p. 45, pl. vi, fig. 51.

Fornasini’s figures of this species, based on the drawings by d’Orbigny in

the “Planches inédites,” show it to be nearly three times as long as broad, with the

chambers flattened and the periphery somewhat truncate, The outside margin

of cach chamber is ornamented with five or six strong, longitudinal costae, The

aperture is produced and a little flared, with a simple tooth. The types were

from the Red Sea. The example figured by Wiesner from the Adriatic is pro-

portionately shorter, being about twice as long as broad, and the chambers are

rounded in transverse section. The five specimens from the Abattoirs Bore are

about twice as long as broad, but otherwise agree fairly well with Fornasini’s

figures, except that the number of costae to a chamber varies from five to two.

Quinqueloculina adelaidensis sp. nov.

(Pl. xv, figs. 5, 7)

Description—Test elongate, slender, quinqueloculine ; chambers rounded ;

sutures slightly depressed; apertural end extended into a long cylindrical neck ;

aperture circular with a phialine lip and simple tooth; wall thin, with a rough

surface, coniposed of minute quartz grains on a base of porcellaneous shell

material. Length, 1-1 mm.; breadth, 0-3 mm.; thickness, 0°25 mm.

Holotype in Howchin Collection, South Australian Museum.

Seven samples of this species were found in the material from the bore.

We have not previously met with anything closely resembling it in any of the

Recent or fossil Australian material we have examined nor is it figured by

Millett, Heron-Allen and Earland, or Cushman in their papers on Indo-Pacific

Recent foraminifera. Cushman (1932, p. 23, pl. v, fig. 12) has figured, under

the name of Quinqueloculina cf. gracilis d’Orb., a specimen from the tropical

Pacific which is perhaps nearest to the present form, but differs from it in having

a polished porcellaneous test with slight traces of longitudinal markings.

Genus Sprrotocurina d’Orbigny, 1826

SPIROLOCULINA ANTILLARUM d’Orbigny

Spiroloculina antillarum d’Orbigny, 1839, p. 166, pl. ix, figs 3, 4. Cushman,

1929, p. 43, pl. ix, fig. 3. Parr, 1932, p. 9, pl. 1, fig. 11.

‘This species was described as a Recent form from the West Indics and is

widely distributed through the Indo-Pacific region, particularly fine examples,

similar to the one figured by Parr, occurring on the South Australian coast. As

a fossil, it is found in the Lower Beds, of Lower Miocene age, at Muddy Creek,

Victoria.

294

Spiroloculina lapidigera sp. nov.

(PI. xv, fig. 10)

Spiroloculina sp, cf. arenaria Brady: Parr, 1932, p. 220, pl. xxii, figs. 41 a,b,

Howchin, 1936, p. 4.

Description—Test irregularly elliptical ; periphery broadly rounded ; chambers

comparatively few, oval in transverse section, evenly curved and each larger in

diameter than its predecessor, resulting in the central portion of each face being

depressed, the final chamber embracing its predecessor at each end and with the

apertural end produced into a short neck, with a phialine lip; the aperture is

rounded and with a simple tooth. The wall is composed of agglutinated sand

grains, mostly of comparatively large size; the larger grains are strongly defined

and highly coloured as black, saffron, and transparent, which show conspicuously

on the white cement background. Length, up to 1:8 mm.; breadth, 1°5 mm.;

thickness, 0°52 mm.

ITolotype from Upper Pliocene, Cowandilla (Government) Bore, 420 feet,

in Howchin Collection, South Australian Museum. ‘There are three examples

from the Abattoirs Bore.

This striking species was recorded by the senior author (loc. supra cit.) as

being one of the most remarkable objects in the Upper Pliocene of the Cowandilla

Bore, from which the holotype has been selected. Parr has also recorded and

figured it, also under the name of Spiroloculina sp. cf. @renaria Brady, as a Recent

form from Westernport Bay, Victoria. It is, however, very distinct from

S. arenaria, from which it may be distinguished by the much larger aperture,

shorter apertural neck, depressed sutures, and the concave centre of the test.

Genus Haverina d’Orbigny, 1839

TIAUERINA ORNATISSIMA (Karrer)

(PI. xv, figs. 8, 9)

Quingueloculina ornatissima Karrer, 1868, p. 151, pl. iii, fig. 2.

Hauerina ornatissima (Karrer): Brady, 1884, p. 192, pl. vii, figs. 15-22.

This beautiful species is represented in the bore by a single example measur-

ing about 0-4 mm. in diameter. It is very well defined, both by its unique

ornamentation and its cribrate aperture. Its usual Recent habitat is in shallow

waters of tropical seas, its range extending from the West Indies through the

tropical Pacific to the Kerimba Archipelago, off Portuguese East Africa. It

occurs on the Great Barrier Reef and in Northern Australian waters, but has not

been previously recorded either as a living form or as a fossil from South Aus-

tralia. It is, therefore, interesting to note that, in addition to the specimen from

the Abattoirs Bore, a similar example was met with in the Upper Pliocene of

the Cowandilla Bore. Figures are given of both specimens,

295

Genus Trtocunina d’Orbigny, 1826

TRILOCULINA OBLONGA (Montagu)

Vermiculum oblongum Montagu, 1803, p. 522, pl. xiv, fig. 9.

Triloculina oblonga (Montagu): Cushman, 1929, p. 57, pl. xiii, figs. 4, 5.

Test long and narrow, of a porcellaneous white, showing three visible

chambers and a simple or bifid tooth, are the fundamental characters on which

considerable variations of a minor kind have been based, resulting in numerous

synonyms. According to the published records, it is very widely distributed.

In the present bore it is moderately common.

TRILOCULINA TRICARINATA d’Orbigny

Triloculina tricarinata d’Orbigny, 1826, p. 299, No. 7; Modeles, No. 94,

Cushman, 1929, p. 56, pl. xii, figs. 3 a-c.

The test, like the preceding species, has three visible chambers, very distinctly

triangular, with a sharp periphery. It 1s common in shallow water on the coasts

of South Australia and Victoria. In the Abattoirs Bore examples are scarce, and

whilst distinctly tricarinate, the segmental angles are a little more rounded than

is generally the case. It occurs also in the Cowandilla Bore.

‘TRILOCULINA CULTRATA (Brady)

Mitiolina culirala Brady, 1881, p. 45: 1884, p. 161, pl. v, figs. 1, 2.

Triloculina cultrata (Brady): Parr, 1932, p. 10, pl. i, figs. 14 a, d.

The records of this species. with the exception of that by Parr from off

Black Rock, Victoria, are from tropical shallow water. It is here represented

by a single example, which appears to be the first occurrence as a fossil.

Genus Frrxtina Cushman, 1921

This species has hitherto been krown only as a Recent form and is one which

has been rarely recorded. In the bore it is, therefore, remarkable that it is very

common, over 200 fine examples having been obtained, the largest measuring

4-2mm. The average diameter of the bore specimens is about $°3 mm., or more

than three times the dimensions given by Brady. Brady’s records were from

Bass Strait, 38 fathoms; Vorres Strait, 155 fathoms; and Humboldt Bay, Papua,

37 fathoms.

It will be noted that, in the figures we give, the aperture is much larger and

at the end of a shorter neck than those figured by Brady. ‘This is merely due to

the much larger size of our specimens, as we find, in a series of specimens from

Bass Strait, the largest specimens (larger than those figured by Brady) have an

aperture similar to that of the bore examples, the apertural neck and aperture

296

becoming respectively shorter and larger with the increase in size of the test.

Besides the bore specimens, the senior author has had the species from Pliocene

beds to the south of Hallett’s Cove, South Australia.

Genus Pyrco Defrance, 1824

Pyrco sp. cf. nuLLomeEs (d’Orbigny )

(PL xv, fig. 6)

There are three specimens which, in external characters, bear a considerable

resemblance to the European Eocene species, P. bulloides. The example figured

has since been accidentally broken, showing the shell to be megalospheric, with

a large proloculus, 0°6 mm. in diameter, followed by three chambers added in

planes 180° apart.

Family OPHTHALMIDIIDAE

Genus NopopacuLarieLtA Cushman and Hanzawa, 1937

Nodobaculariella cultrata sp. nov.

(Pl. xv, fig. 14, a, 6)

Description—Test strongly compressed, periphery subacute with a thin keel ;

chambers in the early portion consisting of an ovoid proloculus, directly followed

by a planospiral chamber extending half way round the proloculus, remaining

chambers roughly triangular in outline with the aboral end recurved, inflated in

the middle, not generally involute, the centre of each face of the shell being

depressed and showing portions of the earlier whorls, three chambers to the adult

whorl; wall ornamented by numerous, fine costae which are parallel to the out-

side margin; aperture elongate, narrow, terminal, with a slight everted lip.

Maximum diameter, 0°65 mm.

Holotype in Howchin Collection, South Australian Museum.

This genus has only very recently been described, and it is therefore of much

interest to find it typically represented in the Abattoirs Bore. Until its early

stages were studied by Cushman and Hanzawa, it was identified with the genus

Vertebralina, which has a different plan of growth, the early chambers being

arranged in a trochoid spiral.

N. cultrata is represented by a single example in the bore material, but the

same form is common in the Lower Beds (of Lower Miocene age) at Muddy

Creek, Victoria, so we fecl justified in dealing with it here as new. The only

specics resembling it is N. aflantica, described by Cushman and Hanzawa (1937,

p. 42, pl. v, figs. 7, 8) from the eastern coast of United States, The chambers

of this are proportionately shorter and it lacks the knife-like keel of N. culirata,

which also differs in having a long, narrow aperture of even width.

This species, which is so common and finely developed in shallow water in

Gulf St, Vincent, is well represented in the bore material. The protean forms

assumed by it in present-day seas are here present and both free and attached

specimens occur. In one case, a colony of seven individuals exhibiting a

Placopsilina-like plan of growth was found attached to a sand grain measuring

5 mm. x 3 mm.

pl. v, fig. 7.

N. lucifuga Defrance var. lapidea Wiesner, 1923, p. 94, pl. xix, fig. 282.

Normally the test of N. lucifuge is wholly porcellaneous, although Brady, in

the “Challenger” Report, noted that the shell at times shows a tendency to

agglutinate sand grains, as in the Miliolidae. ITis fig. 12, on pl. xv, represents

one such example. According to Brady (1884, p. 134), the examples of

N. lucifuga figured by him were from the coast of Tripoli and from the beach

near Melbourne, Australia, but he did not give the locality for each specimen.

Nuttall (1927, p. 211), in his paper giving the localities whence the foraminifera

figured in the “Challenger” Report were derived, states that figures 13-15 repre-

sent specimens from the Gulf of Bombah, Tripoli. Tt is probable that the remain-

ing figured specimens were from Australian waters. The locality given, “beach,

near Melbourne,” suggests that the material was some of that studied by Parker

and Jones (1865, List No. 30) and which Parr has stated (1932, p. 1) was almost

certainly from the coast of South Australia. We have seen nothing like the

specimens under discussion in any Victorian material, although they can be

matched in almost any shallow water gathering from Gulf St. Vincent.

The agglutinated form of N. lucifuga, to which Wiesner has given the name

of var. lapidea, is common in Gulf St. Vincent, and Parr has found it to be

frequent in shore sand at Port Fairy, Victoria, where it occurs to the exclusion

of the typical form. Outside Australian waters, it seems to be of very rare

occurrence, the only records of it appearing to be the two given above. Millett’s

was from the Malay Archipelago, and that of Wiesner, who named the variety

on a single specimen, from the Adriatic.

Specimens occur fairly commonly in the Abattoirs and Croydon Bores, the

best examples being obtained from the latter. Most of them have been attached

during life, but one, apparently free, specimen, which is figured (pl. xv, fig. 2)

was found, This shows an irregular slit-like aperture, which has not been

observed ir, any of the adherent examples. The shell of var. lapidea is more

strongly built and generally larger than is usual in the typical form of N. lucifuga.

In the bore, incomplete specimens 5 mm. in length were met with. The sand

grains incorporated in the wall consist of clear quartz and, in cross sections, are

seen to be embedded in the cement but have an even face at the surface.

Elphidium rctatum sp. nov.

(PI. xvii, figs. 1, 2, 4)

Elphidium (?) macellum (Fichtel and Moll): Howchin, 1936, p. 3.

Description—Test strongly compressed, slightly umbonate, sides sloping

evenly in most cases from the umbo to the subacute periphery, occasionally the

sides are slightly depressed near the margin; chambers very numerous, up to

56 in the adult whorl, not inflated, of nearly uniform height throughout; sutures

distinct, limbate and raised, recurved at the outer end, except in the last quarter

whorl, when they are straight; retral processes extending as cross bars across

the full width of the chamber, 30 or more in the adult chamber, towards the

outer end of the chamber the retral processes are crossed by one or more ridges

running parallel to the sutures and so forming a delicate, cross-lines meshwork

on the marginal surface of the chamber; umbo with numerous small irregular

pits, aperture a series of small rounded openings at the base of the sharply-

triangular apertural face. Diameter, up to 2°9 mm.; thickness, to O-7 mm.

Holotype from shore sand, Kingston, South Australia, collected by Dr. W. G.

Torr and in Howchin Collection, South Australian Museum.

In Part IT of the senior author’s series of geological notes on the deep

borings in the Adelaide Basin (loc. supra cit.), he drew attention to the occurrence

of a species in the Cowandilla Bore which he doubtfully referred to Elphidiuim

macellum. Subsequently, on examining some shore sands from Kingston, South

Australia, collected many years ago by Dr. W. G. Tort, the same form was Tound

to be very common. When further examples of a like kind were met with in

the Abattoirs Bore, it was decided to give them specific distinction. The slinmness

of the test, as well as the sharp peripheral edge, renders the shells liable to injury

by weathering, which is seen in the Recent specimens in part, as well as the fossils.

Under such circumstances, it has been deemed advisable to select a Recent example

as the holotype.

300

As already noted, the species is common in the shore sand from Kingston.

As a fossil, it appears to be limited to the Upper Pliocene in the Adelaide Basin,

where it is of rare occurrence, one example having been found in the Abattoirs

Bore and another in the Cowandilla Bore. The former is 2:0 mm. in diameter,

and the latter 1-80 mm,

Elphidium adelaidense sp. nov.

(PI. xvili, fig. 7; pl. xix, figs. 5, 6)

Description—Test strongly compressed and umbonate, periphery acute, but

not keeled; chambers very numerous, 40 or more in the adult whorl, of about

uniform height throughout, low and slightly recurved; very slightly inflated ;

sutures indistinct; retral processes numerous, up to 22 in the adult chamber,

extending across the surface of the chamber, or occasionally only a little forward

and backwards from the suture line and so forming a double series of shallow

pits bordering each chamber, the large umbo with numerous, very shallow,

irregular pits; aperture a series of small, obscure, rounded openings at the base

of the sharply-triangular apertural face. Diameter, up to 2-9 mm.; thickness, to

1-1 mm. Usually the specimens do not exceed 1-7 mm. in diameter.

Holotype in Howchin Collection, South Australian Museum,

This species is not uncommon in the Upper Pliocene of the Abattoirs Bore

and appears also to occur in the Miocene of the bore. ‘The most closely related

species is possibly 1. chapmani, described by Cushman (1936 (2), p. 80, pl. xiv,

figs. 6 a, b) from the Miocene of Neumerella, Victoria and herein recorded from

the Miocene of the bore. ‘his is a much smaller form, with fewer chambers

(25-30), a proportionately thicker test, and a different development of the retral

processes.

Small examples of this species, which was described from the T.ower Miocene

of the Altona Bay Coal Shaft, near Melbourne, are common in the Upper

Pliocene of the bore. It was also recorded from beds of similar age in the

Cowandilla Bore by the senior author, who noted its wide distribution in the

Australian Tertiaries. While it has hitherto been referred to the genus FRolalia,

it appears to be a trochoid form related to Elphidium and is accordingly trans-

ferred to the genus Polystomellina,

conditions, and is also known from the West Indies. Two specimens were

This species is better known as Orbitolites duplex, under which name it

was described by Carpenter in his work on the Orbitolites of the “Challenger”

Expedition. Cushman, however, after an examination of the types of Amphisorus

hempriciii in the Ehrenberg colleciion in Berlin, considers that Carpenter’s

species is a synonym of the older form.

A. hemprichii occurs on the Great Barrier Reef and elsewhere in the warmer

seas of the Indo-Pacific region, as well as in the Mediterranean and the West

Indies. Two specimens, both very characteristic, have been obtained from the

Upper Pliocene of the Adelaide Basin; the larger, from the Croydon Bore, has

a diameter of 5 mm. The other is from the present bore. When these are

mounted in fluid and examined by transmitted light, a clear distinction is seen

between the single layer of chambers around the centre and the duplex arrange-

ment of chambers in the latter portion of the shell.

This species frequently occurs in great numbers in shallow water in the

warmer parts of the Indo-Pacific, often attaining a large size. its most southerly

record appears to be that by Chapman and Parr (1935, p. 3) from the Great

Australian Bight, off the coast of Western Australia. In the Lower and Upper

Pliocene of South Australia it is a frequent fossil. In the present bore material

fragments occur in the fine sand, and in one of the sandy nodules which occur

in the “white sand” horizon, an impression measuring 20 mm. in diameter

was seen.

There is a small example which measures 0°55 mm. in diameter. It is inter-

mediate between the typical form of this species and Discorbis australis Parr,

which has heavily limbate sutures. It also bears some resemblance to

Tretomphalus concinnus (Brady), when the balloon chamber of the latter is

missing. 7. concinnus attains a diameter of 0°25 mm. only and the shell is very

thin and transparent, with the perforations much smaller and less conspicuous

than those of D. globularis.

This species has been dealt with at length by the junior author (loc. cit.)

in 1932 as a variety of the European Eocene D. vesicularis. He now considers

that the Australian form should be given specific rank, and it is here treated

accordingly.

D. dimidiatus is perhaps the most distinctive foraminifer occurring in

shallow water on the southern coast of Australia reaching its finest development

in Gulf St, Vincent. In the present bore a few examples were found, one measur-

ing 1-2 mm. The species also occurs in the Lower Pliocene of the Muddy Creek

area, near Hamilton, Victoria.

Discorbis cycloclypeus sp. nov.

(PL xvi, fig. 11; pl. xviii, figs. 5, 12; pl. xix, fig. 13)

Description—TLest trochoid, almost cireular in outline, biconvex, the central

portion of the superior face dome-shaped and surrounded by a flattened border,

inferior surface only slightly convex; periphery subacute; chambers 10 to 11 in

the last-formed whorl, increasing gradually in size as added, not inflated; sutures

303

on dorsal side barely visible unless the shell is moistened, oblique, flush, gently

recurved on the ventral side and very much depressed; wall smooth and not

distinctly perforated in the earlier whorls, coarsely perforated in the last-formed

whorl; wall thickened at the centre of the inferior face; aperture an arched slit

at the base of the last-formed chamber. Diameter up to 1°5 mm., height to 1 mm.

Holotype in Howchin Collection, South Australian Museum.

This species is one of the D. vesicularis group and appears to be quite

distinct from any previously described form. It connects /). balcombensis

Chapman, Parr, and Collins, from the Miocene of Victoria, with D. dimidiatus

var. acervulinoides Parr, from Gulf St. Vincent, but has consistently a larger

number of chambers to the whorl than these two species. It may also be dis-

tinguished from D. balcombensis by its strongly-depressed sutures on the ventral

side, and from the other form by the shape of the upper side of the shell, which

recalls a rounded, convex shield, thickened in the centre. Examples are fairly

common in the Upper Pliocene of the Abattoirs Bore and the species also occurs

in the Lower Pliocene of the Muddy Creek area, in Victoria.

This rarely recorded species was originally described from “Australian coral

reefs,” and, with the exception of some fossil specimens attributed to it by

Heron-Allen and Earland from Selsey Bill, Sussex, England, it appears io be

confined to the warmer parts of the Indian and south-western Pacific Oceans

and the late Tertiary of Australia. It is here doubtiully referred to Galloway’s

genus LEpistomaria, the genotype of which is Discorbina rimosa Parker and

Jones. The characters of this genus are defined by Cushman in the second edition

of his book, “Foraminifera. Their Classification and Economic Use” (1933,

p. 240), as follows: ‘lest trochoid, dorsal side with regular chambers, ventral

side with supplementary chambers or alar projections toward the umbilicus,

which is covered; wall calcareous, finely perforate; apertures ventrally at the

304

periphery of the secondary chambers, with supplenientary apertures dorsally at

inner edge of chamber along the suture between it and the preceding chamber,

narrow, elongate.” These do not accord with the structure of the present species,

which has been worked out by Heron-Allen and Earland (1915, p. 698) in their

Kerimba Monograph. The junior author, who has devoted a considerable

amount of time to the investigation of the position of the species, is inclined to

the opinion that it represents a new generic type, but, pending the examination

of the type specimen of Discorbina rimosa, this cannot at present be decided.

Eight examples of this form were met with in the Abattoirs Bore material,

and it occurs also in beds of similar age in the Glanville Bore. There is one

very large specimen from the Glanville Bore measuring 4 mm. across, the whole

of the shell wall being extremely thick and with the surface largely covered by

undulose ridges of imperforate shell material (pl. xvii, figs. 5, 6). Those from

the Abattoirs Bore are typical except one or two which are similar to Discorbis

dimidiatus, except that they have the second aperture in the septal face, which

is a feature of the present species (pl. xvii, figs. 11, 12).

Miniacina iminuta (Chapman)

Family LAGENIDAE

Genus Denratina d’Orbigny, 1826

DENTALINA OBLIQUA (Linné)

(PI. xvi, fig. 5)

For references, see this species under Part I.

There is one large example measuring 4°5 mm. in length. Similar specimens

are common in the Miocene of Victoria.

DENTALINA sp. cf. VERTEBRALIS (Batsch)

(PI. xvi, figs. 6, 7)

There are four specimens, one curved (pl. xvi, fig. 6) and three straight,

which may belong to this species. Batsch’s type-figure (cde Cushman, Contr.

Cushman Lab., vol. vii, pt. 3, 1931, pl. viii, fig. 20, where it is reproduced)

represents a broken specimen, almost straight, and increasing rather quickly in

diameter, with fairly numerous costae which are continued throughout the length

of the test. Cushman’s second figure (in the same work) of an example from

the type locality, Rimini, on the Adriatic, shows another straight shell, with well-

307

defined suture lines of clear shell material and only about eight costae. The

dentaline specimen we figure is, in the earlier portion of the shell, fairly close to

Cushman’s second figure, but additional costae are developed in the latter portion.

The three nodosarian examples are short, with a maximum of six chambers, and

the number of costae is respectively 8, 12, and 16. The sutures are somewhat

depressed.

Genus FronpicuLaria Defrance, 1826

FRONDICULARIA LORIFERA Chapman

(PI. xvi, fig. 4)

Frondicularia lorifera Chapman, 1913, p. 171, pl. xvi, fig. 6.

One typical example was found. This very distinct species was described

from the Miocene of the Mallee bores in Victoria and does not appear to have

been since recorded. The junior author has, however, specimens from the

Lower Beds at Muddy Creek and from Neumerella and Torquay, all in the

Miocene of Victoria. The shell varies considerably in outline. Normally it is

lanceolate, but may be rhomboid or spatulate. The surface is flat and occasionally

depressed along the median line. ‘he most characteristic features are the thick

shell-wall and the exceptionally heavy, raised, strap-like layers of clear material

on the suture lines. The proloculus bears, on each side of the test, two raised

costae of similar material.

Family POLYMORPHINIDAE

Genus PseupopoLyMorrimiNa Cushman and Ozawa, 1928

PskEUpOPOLYMORPHINA RUTILA (Cushman) var. PARRI Cushman and Ozawa

(PI. xvii, fig. 14)

Pseudopolymorphina rutila (Cushman) var. parri Cushman and Ozawa, 1930,

p. 100. Parr and Collins, 1937, p. 201, pl. xiv, figs. 4 a-c.

This species has hitherto been known only from the Miocene of Rocky

Point, Torquay, Victoria, where is was collected by the junior author, so it is

noteworthy that a typical example has been found in the Miocene of the

Abattoirs Bore.

Genus PotyMorPHINA d’Orbigny, 1826

PoLyMoORPHINA MYRAE Parr and Collins

(PL xvi, figs. 9, 10)

Polymorphina myrae Parr and Collins, 1937, p. 203, pl. xv, figs. 4 a-c.

‘The presence of this species in the Miocene of the bore calls for special

remark for, as far as we are aware, it does nut occur elsewhere in beds older

than the Lower Pliocene. The types were from the Upper Beds at Beaumaris,

Victoria, to which it has previously been confined. There are two specimens

from the bore, one, which is immature and with the initial end bearing a short

spine (pl. xvi, fig, 10), and another which is a mature, typical example measuring

2°35 mm. in length (pl. xvi, fig. 9).

308

Genus SIGMOMORPHINA Cushman and Ozawa, 1928

Sigmomorphina subregularis sp. nov.

(Pl. xviii, figs. 2, 11)

Description—Test comparatively large, oval or sub-rhomboidal, about 14

times as long as wide, and thickness half the width; a median sigmoidal longi-

tudinal ridge on both sides, margin of shell subacute; chambers numbering about

16 in the adult, compressed, long, arranged in a clockwise sigmoid series, each

chamber removed much farther from the base, those on the right hand side with

a pronounced median ridge; sutures on the right hand side of the median line of

the shell much depressed, on the left hand side slightly depressed; wall smooth

and comparatively thick; aperture radiate. Length of holotype, 2:55 mm.; width,

1:5 mm.; thickness, 0°78 mm.

Holotype in Mowchin Collection, South Australian Museum.

This very distinct species is represented by six examples. It may be com-

pared with S. pseudoregularis Cushman and Thomas (1929, Journ. Pal., vol. iii,

p. 178, pl. xxiii, figs. 5 a-c), from the Eocene of Texas, U.S.A. This is one-

third of the size of the present species; while the shell has a similar median fold,

the chambers are arranged in an anti-clockwise sigmoid series and the centre of

each chamber on the right hand side of the shell is not ridged.

Family NONIONIDAE

Genus Noniron Montfort, 1808

NoNioN NovozEALANDICcUS Cushman

(PI. xviii, fig. 15)

Nonion novogealandicum Cushman, 1936, (1), p. 66, pl. xii, figs. 6 a, b.

‘The types of this species were from the Upper Oligocene of Motutara Point,

Kawhia Iarbour, New Zealand. One typical example, 0°90 in length, was found

in the bore material.

Genus ErpHipium Montfort, 1808

Elphidium sp. cf. adelaidense sp. nov.

(Pl. xvii, fig. 3)

There is one specimen which may belong to this species which we have

described from the Upper Pliocene of the bore. It is more compressed than

those from higher in the bore.

ELPHipIUM CHAPMANT Cushman

Elphidium chapmani Cushman, 1936 (2), p. 80, pl. xiv, figs. 6 a, b.

Four examples were found. They measure about 1:2 mm. in diameter and

otherwise agree with Cushman’s description and figures, except that the edge

of the test is slightly keeled. The species was described from material forwarded

to the author by Parr from the Miocene of Neumerella, near Orbost, Victoria.

309

ELPHIDIUM sp.

(PI. xviii, fig. 8)

The figure represents a unique example of what is probably a new species.

The test is stout and umbonate, the thickness being one-half of the diameter in

side view. ‘There are 16 chambers in the outside whorl; these are of nearly

uniform size and shape and are slightly inflated. The sutures are rather indistinct

and depressed. The chamber walls are covered closely with raised cross bars

of shell material parallel to the periphery and, with the beads on the umbones,

giving an ornate appearance to the test. The diameter is 1-2 mm., and the thick-

ness O°6 mm. In the absence of further material, it has been deemed inadvisable

to make a specific determination.

Family CAMIERINIDAE

Genus OpercuLina d’Orbigny, 1826

(2?) Operculina umbonifera sp. nov.

(PI. xviii, figs. 3, 4, 6, 18, 14)

Desecriplion—Test a little longer than broad, slightly asymmetrical, periphery

rounded or subacute, rarely faintly lobulated in the last two or three chambers,

the central half of each side of the shell strongly umbonate, the umbo composed

of laminated shell material, finely perforate; whorls numbering usually three,

each whorl added obliquely so that the axis of the test in vertical section is curved ;

12 to 13 chambers in the last-formed whorl, of uniform shape, increasing slightly

in size as added; sutures indistinct or invisible, very slightly recurved; wall thick,

laminated, closely and distinctly perforate in sections of the shell; canal system

present but weakly developed, apparently consisting of interseptal canals and a

few tubular passages in the “marginal cord” in the plane of coiling; aperture a

narrow, curved slit placed a little to one side at the hase of the triangular face

and next the preceding coil, Length of holotype, 1-3 mm.; breadth, 1-1 mm.;

thickness, 0°75 mm.

Holotype in Howchin Collection, South Australian Museum,

It is difficult to place this species satisfactorily with the material available.

There can be little dowbt that its affinities are with the Camerinidae, near the

genus Operciulina, but the test of this genus and of related genera is invariably

bilaterally symmetrical. Possibly we have a new generic type, but, as there are

only five specimens, three of which have been used to make sections, further

specimens are required before the position of the species can be satisfactorily

ascertained.

OPERCULINA VICTORIENSIS Chapman and Parr

(PI. xviii, fig. 10)

Operculina victoriensis Chapman and Parr, 1938, p. 284, pl. xvi, figs. 3-8; text

fig. 2.

This species, which has just been described from the Miocene of Victoria,

is represented by three typical specimens, the largest of which measures 2°3 mm.

Its range in Victoria is from the Lower to the Middle Miocene.

Family ROTALIIDAE

Genus Rotatia Lamarck, 1804

Rotalia verriculata sp. nov.

(Pl. xix, figs. 8, 9, 11, 15)

Rotalina calcar Chapman (non Calcarina calcar d’Orbigny), 1910, p. 289, pi. hii,

fig. 2.

Rotalia caleay Weron-Allen and Earland (non Calcarina calcar d’Orb.), 1924,

p. 180.

Calcarina defrancii Weron-Allen and Earland (non d’Orbigny), 1924, p. 182.

Deseription—Test trochoid, plano-convex to biconvex, the ventral side always

the more convex, periphery lobulate, broadly rounded to subacute, sometimes with

irregular spinose projections on the later chambers, umbilical area with a coarsely-

beaded plug or closed and bearing one large rounded bead of shell matcrial;

chambers usually 12 or 13. in the last-formed whorl, increasing gradually in size

as added, strongly inflated on the ventral side, only the later chambers well

inflated on the dorsal side; sutures much depressed on the ventral side and

frequently in the last quarter of the outside whorl on the dorsal side, slightly

recurved on both faces; wall thick, closely covered on the ventral side with an

ornament of raised cross bars parallel to the periphery and sometimes numerous

large raised beads in the centre of the test and along the median line of the earlier

chambers, dorsal side thickly studded and at times completely covered with

tubercles of exogenous shell-growth; septa double; aperture an elongate slit at

the inner margin of the ventral side of the last chamber. Diameter up to 2-8 mm.;

height, to 1 mm.

Holotype in Howchin Collection, South Australian Museum.

This species is very common in the Lower Miocene limestone of the Filter

and New Quarries at Batesford, Victoria, and occurs elsewhere in Victoria in

beds of a similar facies and age. Chapman (loc. supra cit.), in his paper “A

Study of the Batesford Limestone,” has given photographs of four specimens

which illustrate well the variations found in the species, particularly in the gradual

loss of the umbilical plug. The specimens from the Abattoirs Bore alsa show

the transition from a form with a solid umbilical plug to one in which it is absent.

dieron-Allen and Earland have referred their Batesford specimens to two species,

those with a strongly biconvex test, solid umbilical stud and projecting spinous

processes to Rotalia calcar, and those with a plano-convex test, almost devoid of

spinous processes, and studded all over with beads of exogenous shell-growth to

Calcarina defrancu. From our material, however, it appears that none of the

features on which these authors have relied for their identification of the two

forms is constant, as, apart from the presence or absence of the umbilical plug,

the Fr. calcary form is frequently almost plano-convex and more often than not

without any peripheral spines, while the C. defrancit form may have a biconvex

test with peripheral spines (vide pl. xix, figs. 8, 9 and 15, and also Chapman’s

bottom left-hana figure). Reference to the original figures of Calcarina calcar

311

and C. defrancii and also C. gaimardii d’Orb., with which Heron-Allen and

Earland compared the present species, will show that the latter is quite distinct.

It appears to be confined to the lower part of the Miocene of Victoria and South

Australia.

Family AMPIISTEGINIDAE

Genus AMPHISTEGINA d’Orbigny, 1826

AMPHISTEGINA HAUERINA d’Orbigny

(Pl. xvi, fig. 1)

Amphistegina haucrina d’Orbigny, 1846, p. 207, pl. xii, figs. 3-5.

A, lessonii Chapman (non d’Orbigny), 1910, p, 294, pl. liii, fig. 6. Chapman and

Crespin, 1932, fig. 3.

This compressed, lenticular form of Amphistegina was described from the

Miocene of the Vienna Basin. Typical examples occur in the bore, and it is

frequently very common in the Lower and Middle Miocene of Victoria.

Family CHILOSTOMELLIDAE

Genus SpHAEROIDINA d’Orbigny, 1826

SPHAEROIDINA BULLOIDES d’Orbigny

(PI. xviii, fig. 9)

Sphaeroidina bulloides d’Orbigny, 1826, p. 267, No. 1; Modeles, No. 65.

Brady, 1884, p. 620, pl. Ixxxiv, figs. 1-7.

There is one example 1-3 mm. in diameter.

Family PLANORBULINIDAE

Genus Pranorsutina d’Orbigny, 1826

PLANORBULINA MEDITERRANENSIS d’Orbigny

(Pl. xix, fig. 12)

Planorbulina mediterranensis VOrbigny, 1826, p. 280, pl. xiv, figs. 4-6; Modeles,

No. 79. Brady, 1884, p. 656, pl. xcii, figs. 1-3.

There are two examples. This species was recorded by Heron-Allen and

Earland (1924, p. 173) from the Lower Miocene of Batesford, Victoria.

Genus PLANORBULINELLA Cushman, 1927

PLANORBULINELLA INAEQUILATERALIS (ITeron-Allen and Earland)

(Pl. xix, fig. 2)

Planorbulina larvata Parker and Jones var. inaeguilateralis Heron-Allen and

Earland, 1924, p. 174, pl. xii, figs. 83-90.

Planorbulinella inaequilateralis (H.-A. & E.): Crespin, 1936, pl. i, fig. 6.

There are two specimens, the larger measuring 1-4 mm. in diameter. This

form was described from the Lower Miocene of Batesford, Victoria, as a variety

of Planorbulina larvata characterised by a convex superior surface and a concave

312

inferior side. Heron-Allen and Earland also recorded P. larvata in the same

paper, this representing the flat form of inaequilateralis. We agree, however,

with Miss I. Crespin, B.A., the Commonwealth Palaeontologist, that P. larvata

does not occur in the Tertiary of Victoria and that the variety inaequilateralis

should, therefore, be given the status of a species. In P. larvata the chambers in

the outside ring are separated from one another by the chambers of the preceding

ring, while in P. inaequilateralis they are contiguous.

The present species has not been found outside the Lower Miocene of Vic-

toria and South Australia.

Genus GYPSINA Carter, 1877

GyYPsINA GLoBULUS (Reuss)

(PIL. xviii, fig. 16)

For references see this species under Part I.

One specimen was found. This widely distributed species is common in the

Lower Miocene of Batesford (vide Heron-Allen and Earland, 1924, p. 183,

pl. xiv, figs. 117, 118).

GYPSINA HOWcIlINI Chapman

Gypsina howchint Chapman, 1910, p, 291, pl. lii, figs. 4 a, b; pl. liii, figs, 3-5.

Heron-Allen and Earland, 1924, p. 183. Crespin, 1936, pl. i, fig. 8, ? fig. 7.

Miss Crespin’s fig. 8, which represents an example from the type locality,

Batesford, shows the surface features of this species very well. The test is dis-

coidal and the faces are slightly convex in the smaller specimens becoming flat

or slightly concave in the larger examples. ‘The surface of the small specimens is

sometimes pustular, but typically the chamber surfaces are flat and surrounded

by a raised limbate margin to each chamber. These margins form a reticulate

surface to the test, the intervening areas being coarsely perforate.

G. howchint has hitherto been known only from the Lower Miocene of Vic-

toria, so it is interesting to meet with a large typical example in the Abattoirs Bore.

This is 2°7 mm. in diamcter.

Family RUPERTIIDALE

Genus CARPENTERIA Gray, 1858

CARPENTERIA ROTALIFORMIS Chapman and Crespin

Parr, and Collins, 1934, p. 572, pl. xi, fies. 44 a-c.

Two typical examples were found in the bore material. his very distinct

species was described from the Lower Miocene of Victoria, in which it is widely

distributed. The present record is the first from outside Victoria.

313

Family HOMOTREMIDAE

Genus Mrntacina Galloway, 1933

MINIACINA MINUTA (Chapman)

Polytrema minutum Chapman, 1910, p. 292, pl. li, figs. 3 a, 6. Heron-Allen and

Earland, 1924, p. 184.

There are three typical specimens of this species, which was described from

the Lower Miocene of Batesford, Victoria, and occurs elsewhere in beds of the

same age in Victoria.

THE OCCURRENCE OF GALLIUM AND GERMANIUM

IN SOME LOCAL COAL ASHES

By W. TERNENT COOKE, D.Sc., A.A.C.I.

Summary

The frequent occurrence of traces of gallium and germanium in coal ash has been pointed out by

Ramage ( I ), Goldschmidt (2), and others (3), and more recently Morgan and Davies (4) have

shown that these elements may become concentrated in certain flue dusts to the extent of one per

cent. or more, so that their profitable extraction becomes possible. The previously known

occurrences of notable concentrations of these elements have been restricted to some very rare

sulphide minerals such as argyrodite and germanite, and therefore the recognition of their

apparently widespread occurrence in appreciable amounts in flue dusts from coal is a matter of

some theoretical and practicable importance. It has seemed of interest therefore to examine some

flue dusts from Australian coals for their content of gallium and germanium.

THE OCCURRENCE OF GALLIUM AND GERMANIUM

IN SOME LOCAL COAL ASHES

By W. TERNENT Cooke, D.Sc., A.A.C.L.

[Read 8 September 1938]

The frequent occurrence of traces oi gallium and germanium in coal ash has

been pointed out by Ramage (1), Goldschmidt (2), and others (3), and more

recently Morgan and Davies (4) have shown that these elements may become

concentrated in certain flue dusts to the extent of one per cent. or more, so that

their profitable extraction becomes possible. The previously known occurrences

of notable concentrations of these elements have been restricted to some very

rare sulphide minerals such as argyrodite and germanite, and therefore the recog-

nition of their apparently widespread occurrence in appreciable amounts in flue

dusts from coal is a matter of some theoretical and practicable importance. It has

seemed of interest therefore to examine some flue dusts from Australian coals

for their content of gallium and germanium.

The procedure followed was that advocated by Morgan and Davies, in which

the dust is distilled with hydrochloric acid of about 6°25 normal (20%). The

germanium was recovered from the distillate as sulphide, after separation of

arsenic, which is invariably present; the gallium was extracted from the residual

liquor by ether, after reduction of the iron to the ferrous state.

In the samples examined considerably less amounts of either element have been

found than those reported by Morgan and Davies for many English coal dusts,

but the presence of both elements has been noted in most of the samples examined.

By working with samples of the order of 100 grammes the analytical results give

a reasonable approximation to the actual amounts of gallium and germanium

actually present in the dusts.

The majority of the dusts available have been from black coal of permo-

carboniferous age, from Newcastle, New South Wales. Those supplied by the

courtesy of the South Australian Gas Company have been the richest so far

examined. Dust from the waste gas flues in the vertical retort house yielded

0-034% GeO,, and 0°084% Ga,O,, while corresponding dust from the horizontal

retorts showed 0°041% GeO,, and 0°073% Ga,O,. Dust from the flues of a

Lancashire boiler burning gas coke contained 0-004% GeQ,.

A sample of spent liquor from a still operating on ammoniacal liquor was

kindly provided for us in a concentrated form by the Gas Company; this liquor

was found to be practically free of germanium,

A sample of dust from the base of the chimney stack of the South Australian

Brewing Company, and derived from Newcastle coal, yielded only 0-002%

Ga,O,, and 0:007% GeO,.

Dust from a Tasmanian coal of mesozoic age, from Stanhope, supplied by

the Tasmanian Cool Storage Company of Launceston, was found to contain

0-005% GeO),, but showed only a trace of gallium.

Three dusts, supplied by the courtesy of the State Electricity Commission of

Victoria, from boiler flues at Yallourn were examined, These dusts from brown

coals of tertiary age yielded only traces of both germanium and gallium. This

relative deficiency of these elements in dusts from brown as compared with

those from black coal agrees with the observations of Tuchs (5), concerning

German lignite.

It has been found possible to effect a concentration in some cases by screen-

ing the dusts; for example, after screening through a 100-mesh sieve the fine

material is sometimes about twice as rich as the original dust.

The possibilities of selectively leaching the dusts with acid or alkaline

reagents with a view to concentration have been examined, but the results do not

indicate that such methods are applicable to this class of material. Germanium

can be leached from the dust by hot concentrated caustic soda, but gallium remains

for the most part in the insoluble residue. Subsequent extraction of the

germanium from the alkaline lye was difficult on account of the large amount of

sodium silicate present. The success achieved by Sebba and Pugh (6) in leach-

ing gallium and germanium from the mineral germanite by sodium hydroxide led

to the hope that their process might be applicable to flue dusts, but the fact that

germanite is a sulphide combination is evidently a factor in the success of the

operation. Apparently the gallium and germanium compounds present in flue

dusts are not in a very reactive form, and in view of the high temperatures to

which these dusts have been subjected, it seems probable that the elements are

present not as simple oxides but possibly as complexes analogous to alumino-

silicates.

Acknowledgment is here made of the courtesy of the several Companies who

supplied and forwarded the samples examined.

AN EXAMINATION OF SOME SOILS

FROM THE MORE ARID REGIONS OF AUSTRALIA

By J. A. PRESCOT and H. R. SKEWES, Waite Agricultural Research Institute

Summary

During the course of the last few years the opportunity has been taken of securing for the reference

collection of soils at the Waite Institute a number of samples from the more inaccessible and arid

regions of Australia through the courtesy of the members of expeditions of exploration into these

regions. Prominent amongst these collectors have been Mr. Michael Terry, Dr. C. T. Madigan and

Mr. N. B. Tindale. The anthropological expeditions from the University of Adelaide have also

afforded a number of opportunities for securing such samples. Material has been received in all

from some fifty localities, and in some cases from several sites in each locality. These localities

may be grouped as representing the following areas: (1) the southern margin of Gibson's Desert

between the Warburton Ranges and Laverton, (2) the Warburton Ranges, (3) the Musgrave Ranges

and adjacent country, (4) the country between the Granites and Lake Mackay and east thereof, (5)

scattered samples north and south of the Macdonnell Ranges, (6) the north-east pastoral country of

South Australia, (7) the Lake Eyre basin, and (8) the southern part of Nullarbor Plain. The localities

are indicated on the map (fig. 1) and in the accompanying key.

The soils are of such diverse origin and so widely scattered geographically

that it is not possible to group them very effectively, and no attempt will be made

in this account to do more than extract the major generalisations.

For a number of sites carefully sampled profiles are available, and the

analytical data for some of these are quoted in full.

MECHANICAL ANALYSIS

Soils from che Desert Interior

A characteristic feature of the samples from the interior proper is the

absence of marked differentiation in the texture of the several horizons. This

is especially so in the more sandy soils. It has proved possible, therefore, to treat

the samples from each site to a depth of 40 inches as one sample and to average

the mechanical analyses to this depth, where such a series was available. Fig. 2

represents, ou this basis, the mechanical analyses for all the sites in the central

and western desert areas and range country apart from one very heavy profile at

Lambina, which is not included.

The range of texture is small and the silt content is very low, the textures

falling into the range of sandy loams with the sands of the sandhills at one

extremity of the range and a few sandy clay Joams at the other. That soils from

such a wide geographical area should have such uniform textural characteristics

indicates some common process of mechanical sorting of the weathered parent rock.

Each dot represents the average composition of samples

toa depth of 40 inches or less. Samples from the sand-

hills are indicated by the hatched area.

Soils from the North-East Pastoral Areas of South Australia

In marked contrast with the true desert soils, the group from the north-

eastern pastoral area of South Australia may be noted. The mechanical analyses

of this group of soils are summarised in fig. 3. The distribution of these analyses

within the texture triangle shows approximately equal proportions of clay and

silt. Most of these soils are calcareous, and there is also evidence of profile

development so far as the occurrence of heavier textures in the subsoils may be

regarded as an index of such development.

Desert Sandhills and Drift Sands

A considerable proportion of the arid interior is covered by sandhills, and

reference in this connection may be made to the work of Madigan (1936). These

324

sandhills are in most cases fixed by desert grasses belonging mainly to the genus

Triodia; mulga is also characteristic of the sandhill country.

The sandhills extend into the less arid regions to the north-west, where they

are fixed by a low tree savannah woodland known as the “pindan,” and to the

south by the dwarf sclerophyll woodland known as the “mallee.”

In all such areas the removal of the native vegetation by stocking or cultiva-

tion results in drift taking place. A series of such loose drifts from the pastoral

areas of South Australia has been specially collected, and a comparison is possible

with samples from the sandhills of the less accessible parts.

The most characteristic feature of the table is the low content of silt and the

invariable presence of clay, varying in amount from 4 to 10 per cent. Even the

loose drifts show this clay, some of which is in the form of aggregates, no doubt

broken up during the course of mechanical analysis. The sandy soils of the

South Australian and Victorian mallee areas show similar characteristics. The

amount of salt present and the reaction is a regional characteristic. The drifts

from the north-east pastoral areas of South Australia are markedly alkaline and

contain calcium carbonate. Those from Gibson’s Desert in Western Australia

are distinctly acid. Gibson’s Desert is characterised by extensive rolling plains

of ironstone gravel, and the parent material from which the sandhills are derived

is undoubtedly acid in character.

Summation curves based on separations by means of sieves of the mechanical

analyses of drift sands. The virtual absence of silt is to be noted. The samples

in addition contain a small proportion of clay uot indicated in the above.

These samples were also subjected to mechanical analysis without a pre-

liminary acid treatment. The samples were dispersed by boiling with water to

which was added a small amount of sodium carbonate. Silt and clay were

removed by gentle rubbing and subsequent decantation. The clean sands were

327

then dried and separated by means of sieves. The summation curves obtained

in this way are indicated in figs. 4 and 5. In the case of the five drift samples,

the mean curve was determined and analysed to determine the frequency distribu-

tion of particles of each of a series of dimensions allowing of eight groups for

each of the standard fractions. The frequency curve of fig. 6 emphasises the

character of these sands which have a modal frequency near the conventional

separation between the coarse and fine sand. The virtual absence of silt in these

soils is also easily to be explained in terms of these distributions.

Two cf the samples (Nos. 2950 and 5199) show anomalies which can be

interpreted in terms of a mixture of two groups of sand grains. The latter sample

is the surface mulch subject to the combined sorting effect of wind and of the rare

heavy rains.

REACTION

All the samples have been examined for reaction (pH), using the glass

electrode. They form an interesting range, with the calcareous soils of the salt-

328

bush steppe of the north-eastern pastoral areas of South Australia as the most

alkaline.

significance

Samples from the Nullarbor Plain have the same character. The soils

range country are in general neutral to alkaline, and those from the

rack and Gibson’s Desert are neutral to acid. It is of some possible

e that these two latter groups of soils are representative of the great

Australian Peneplain. Presumably the acid conditions are an index of former

wetter climatic conditions thus confirming the evidence provided by the abundant

ironstone gravel.

SoLuBLE SALTS

The vast majority of the samples examined are relatively free of salt with

the exception of the South Australian samples from the pastoral areas and from

the regions of Lake Eyre and the Nullarbor Plains. None of the remaining surface

soils contains as much as 0:05 per cent. of total soluble salts, and few of the sub-

soils contain as much as 0°10 per cent.

The saltbush country shows, however, much higher amounts, and reference

may be made to the data given later relating to individual soil profiles. Some

exceptionally saline soils may be noted, however—these have usually been asso-

ciated with bare patches and wind-swept areas. It is apparent that many such

bare areas are not duc so much to erosion and loss of vegetation by stocking as

to inherent infertility through the natural presence of soluble salts.

Some examples of these more saline areas are tabulated below.

Reference may also be made here to the nature of samples from the immediate

vicinity of salt lakes and from the bed of the lakes themselves. Madigan (1930)

has already reported upon the muds from Lake Eyre. Samples have been

examined during the course of the present work from Lake Throssell, 200 miles

south-west of the Warburton Range, and from Lake Mackay. These results

are quoted in the following table.

CHEMICAL ANALYSES

As a measure of the fertility level of these soils analyses have been made on

representative samples using the standard hydrochloric extracts for phosphate

and potash, the method of dry combustion for carbon, and the Kjeldahl estima-

tion for total nitrogen. These data are given in Table V, together with correlated

information such as the clay content and total salts,

Two ratios have been calculated—those of carbon to nitrogen and of potash

to the clay as estimated by the international method of mechanical analysis. ‘Ihe

ratios of carbon to nitrogen tend towards the low side, with three very low values

for samples No. 5200, 5192 and 1306. ‘The phosphate levels are variable and

show some relation to the native vegetation. The outstanding feature in this

respect is the high level of phosphate in the soils of the north-eastern pastoral

region of South Australia—a level which is higher than that generally encountered

in the wheat belt further south.

The ratio of potash to clay shows again two outstanding generalisations—

the acid soils of the Granites country and of Gibson’s Desert showing low ratios in

this respect, further evidence of leaching during a former geological cycle, while

the alkaline soils of the pastoral region mentioned above show uniformly high

values.

This region has a high reputation amongst stock owners for the production

of healthy sheep, and from the point of view of soil fertility must be regarded as

one of the outstanding areas in South Australia.

Sample No. 3431 shows a very high level of fertility—this sample is taken

near the native waterhole at Ernabella in the Musgrave Ranges and is associated

with an aboriginal camping ground,

The native vegetation of these semi-arid and arid soils covers a range which

includes two main associations of Triodia, those of the desert sandhills and those

of the sand plains of Gibson’s Desert and of the Tanami country; the associations

including mulga and grasses, the low tree savannahs of the plains between the

ranges and the shrub steppes of saltbush or bluebush.

From the native vegetation recorded with many of the samples received, a

tentative scale of fertility may be attempted. Yriodia (spinifex or porcupine

grass) is an index of low fertility, while saltbush appears to be associated only

with the highest level of plant nutrients.

In general the level of phosphate is the main index of fertility, and on this

basis the following generalisations may be derived.

Vegetation Range of Phosphate Content (P,O,)

Porcup-ne grass _ ma ced 0-006 — 0-023%

Mulga with grass _.... core vat 0-023 — 0-053%

The table suggests three levels of fertility, the first up to 0-023%, the second

from 0-023% to 0-060%, and the third above 0-060% P,O,.

SOME CHARACTERISTIC PROFILES

Profile development in desert and semi-desert areas is little understood, and

much field work will be required before a full interpretation is possible. Field

estimates of structure and texture are not usually available owing to the conditions

under which the samples have been collected, but a selection of samples represent-

ing twelve profiles has been taken and the analytical data relating thereto are

given below.

The leaching factors responsible for the development of horizons in soil

profiles are not common in the desert environment, so that marked structural

differences in the successive depths of soil are not to be expected. Attention may

be called, however, to the lamination that occurs in soils from the semi-desert

regions of Western Australia (Teakle, 1936). The type of structure described

by Teakle can only occur in the closed basins of the areas of internal drainage,

characteristic of arid regions, and represents a process of accumulation and

cementation rather than of leaching and deflation. Gautier (1928) has called

attention to the importance of water as the main geological factor responsible for

erosion in desert regions—wind plays a subsequent part mainly in the modelling

of the surface features. No cases of lamination have been met in the samples

under present consideration.

One feature, however, of the desert grassland and of the shrub steppe is the

accumulation of a loose drift with plant debris round the base of the grass clump

or of the bush. This drift may be considered as a super-surface or Ao horizon

and is usually of loose texture and forms an admirable sced bed for the ephemeral

and seedling perennial vegetation. The destruction of the perennial grasses or

bushes which constitute the nurse plants, with the consequent loss of this charac-

teristic horizon, may be considered to be a major source of difficulty in the re-

generation of the vegetation of these areas.

The selected profiles will be dealt with individually, and the complete data

relating to them recorded as a source of reference material for other workers in

this field. The site numbers quoted are those given on the map of fig. 1..

This profile represents a heavy type of soil frequently associated with gibber

country.

The surface two inches differs markedly in texture from the soil at greater

depth. Surface wash and the removal of the finer particles by wind, rather than

leaching, no doubt contribute to this change. The absence of gravel or stone in

the lower horizon is noteworthy.

The reaction is neutral in the surface to markedly alkaline at the lower

depths. ‘Ihe fertility level is moderately high.

Site No. 20-—-Warburton Range, Western Australia. Collected by Michael

Terry. Camp 25 on expedition of 1931, 300 yards from

Warburton Creek.

The sample is collected from a travertine rise on the west bank of the creek.

The flood waters, in overflowing on the hot dry banks, deposit calcium carbonate,

giving rise to travertine or “opaline” rises which are specially characteristic of the

rivers of the Murchison and Gascoyne districts and of the north-west of Western

Australia,

The differences in the three horizons sampled are associated principally with

the differences in the content of calcium carbonate. ‘The fertility level in terms

of plant food is low.

All tae samples are very gravelly, the proportion of gravel in the three

original samples being successively 27, 55 and 51 per cent. This gravel was cal-

careous in character.

Site No. 17—Gibson’s Desert, Western Australia, 80 miles from Mazlett’s

Well, in the Warburton Range. Collected by Michael Terry.

The samples are taken from an ironstone gravel flat—the gravel repre-

senting, successively, 32, 41 and 37 per cent. of the original samples. The soils,

to a depth of 18 inches, are acid.

The fertility level with respect to phosphate is moderate, with respect to

potash it is low. The gravel has been found (Prescott, 1934) to contain 49-0 per

cent. of iron oxide (Fe,O,).

Site Nc. 10-——Muloorina Peninsula, South Australia; south of Lake Eyre,

5 miles from the Lake. Collected by J. A. Prescott.

This series of soil horizons is representative of the consolidated sandhills

characteristic of the immediate vicinity of Lake Eyre. The surface of the country

is relatively loose and, when eroded away, reveals a firm subsoil with a wide

polygonal pattern of gentle domes. No cracks were to be observed between them

at the time of sampling (Madigan Expedition, Camp 1, Bore 9, December, 1929).

The only vegetation was dead cotton bush (Kochia aphylla) and saltbush, with

occasional ncedlebush (Hakea).

In the vicinity of the Lake gypsum is very comrnon. The mud of the Lake

itself consists of a saturated solution of brine with crystals of gypsum and common

salt, some calcium carbonate and much sand. Reference may be made to Madigan

(1930) for further details. he mean annual rainfall at Muloorina is 4 inches,

so that leaching is restricted to the most soluble constituents. Calcium carbonate

is present throughout the profile but has been leached down to a certain extent,

reaching its maximum in the fourth nine inches. Sodium chloride is at its

maximum in the third nine inches, while gypsum becomes prominent at 54 inches.

For such light soils the phosphate content (0°039%) is fairly high. The samples

are all markedly alkaline.

Site No. 5—Glenorchy, South Australia. Springs paddock. Collected by

J. A. Prescott. Country carrying saltbush and bluebush, with

mulga in immediate neighbourhood.

The first sample represents the super-surface horizon (Ao) round the

bushes which act as nurse plants—this drift provides a favourable seed bed, and

it is the loss of this horizon by wind erosion which gives rise to the major soil

problem in relation to pasture regeneration in these areas.

The horizon is measured from the general surface of the soil upwards, and

not downwards. Soils at Glenorchy are affected by the neighbourhood of granite

outcrops. They are light in texture and not particularly rich in plant foods. The

samples contained 1 to 2 per cent. of quartz gravel.

Summary

Tasmania has an area of 16,778,000 acres, of which 47 percent consists of unoccupied country. A

relatively small area is cultivated; the area under crop in 1936-7 was 263,251 acres, together with

45,060 acres of fallow land. The land utilization regions of the country have been analysed in a

recent publication (Lowndes and Maze, 1937).

Tasmania has an area of 16,778,000 acres, of which 47 per cent. consists of

unoccupied country. A relatively small area is cultivated; the area under crop in

1936-7 was 263,251 acres. together with 45,060 acres of fallow land. The land

utilizaticn regions of the country have been analysed in a recent publication

(Lowndes and Maze, 1937).

The first European settlement in Tasmania was established by Lt. Bowen

at Risdon Cove, in September, 1803. Colonel David Collins moved the settlement

to the present site of Hobart, in February, 1804. In 1804, also, Colonel Paterson

formed a settlement near the mouth of the Tamar; it was removed to the present

site of Launceston two years later. ‘The northern and southern portions of

Tasmania were administered from [Launceston and Hobart, respectively, until

1812, when the colony was united under one administration with headquarters

in Tlobart. During the first 20 years of its development Tasmania was an

appendage of New South Wales; it was proclaimed a separate colony in 1825.

The native inhabitants of the island had not practised any form of agricul-

ture, so that the European settlers entered upon a country whose native vegetation

had been undisturbed except for occasional bush fires. A system of grants of

free lands to settlers was introduced within the first ten years of settlement; the

system remained in force until 1864, at which time the area of approved grants

amounted to 14 million acres. The early selections of land were naturally made

about Hobart and Launceston. Development extended from these centres along

the Derwent and the Tamar. The direction and rate of progress of the advance

of settlement was determined largely by the physical features of the country and

the native vegetation.

The sheep numbers for the five-year periods given in Table I have been fitted

to the Verhulst-Pearl logistic curve, having the formula:

1670

tae Le ee 780r8l245 - 018125

The upper asymptote, 1670, was obtained by taking the average population for

the five-year periods 1859-1924. The calculated curve is shown in fig. 1; the

observed and calculated figures are given in Table I.

The curve shows that, under the conditions of development of the sheep

industry up to 1846, the expected saturation density on the natural pastures of

the State would be 1,670,000 sheep. This density was attained towards the end

of the 1840’s. From the beginning of the 1850’s onwards the population oscillated

about this value for about 70 years. Compared with South Australia (Davidson,

1938) the rate of growth is slower. his is related to differences in the physical

features, climate and early political history of the two States. The marked

temporary fluctuations in sheep numbers found in South Australia, due to drought

periods, are less pronounced in the case of ‘Tasmania,

III Procress or THE SHEEP POPULATION

(a) First Period, 1804-1846

In the first decade of settlement, development was necessarily slow. Sheep

raising for wool production really began in 1820, when 300 merino rams were

imported into Tasmania from Capt. McArthur’s flocks in New South Wales. The

344

settlers placed their flocks on grazing lands along the Derwent and the Tamar

and extended into the Midlands. The savannah country of the Midlands afforded

excellent pasturage and the climate favoured the production of fine quality merino

wool. In 1843 the system was started whereby prisoners were hired out to

settlers on probation, at low rates of pay; this provided labour for pastoral

developments, and by 1846 the ordinary leased lands from the Crown amounted

to 337,000 acres. It was during this period, in 1836, that the two sons of Thomas

Henty went over from the Tamar and established a settlement at Portland Bay.

This was the beginnings of the foundation of Victoria, which became a separate

colony in 1850. Tasmania supplied rams with high quality fleece to the Victorian

graziers during these early years, which was a useful source of income for the

Tasmanian sheep farmer.

(b) Second Period, 1847-1858

The rapid rise in sheep numbers during this period suggests the influence of

environmental factors differing from those of the first period. These factors are

associated primarily with a marked expansion of grazing areas and heavy stocking

of sheep runs. Whyte (1871) states that, owing to the poor market for fat sheep

in Tasmania, the sheep farmer concentrated on wool production and sheep runs

were heavily overstocked. It appears to have been the practice of contractors

to supply the meat requirements of military and prison establishments in Tasmania

by importing sheep and bullocks from the mainland; the net imports of sheep

during 1849-54 were 290,400. With the marked extension of grazing activities

ful information about this period.

345

the area of ordinary leased Crown lands rose suddenly in 1847 to 1,063,000 acres ;

by 1853 the area had increased to 2,314,000 acres.

In the latter half of the period the sheep numbers decreased rapidly and

finally came to rest about the calculated curve. The conditions which led to the

temporary increase in sheep numbers were evidently unstable. The occupied

natural pastures could not carry permanently this high density of population.

This is clearly shown by the lower average level of saturation (1,670,000) which

obtained for the next 70 years.

Several factors were associated with this fall in sheep numbers. The area

of ordinary Crown lands held under lease decreased after 1853, and was 536,000

acres less in 1858. The sheep farmer was also learning from experience that it

was more profitable to stock his pastures with proper regard for their sheep-

carrying capacity ; a smaller number ot well nourished sheep carry more wool than

a larger number of impoverished shcep on overstocked pastures.

After 1851 there was an increased demand for fat sheep in Tasmania; the

importation of sheep declined from 65,089 in 1851 to 11,786 in 1858; the price

of mutton in Hobart appreciated from 3d. per Ib. in 1851 to 6d. in 1852 and

84d. in 1853. These factors revived the interest of the sheep farmers in fat sheep

for local markets, which would bring about a reduction in the number of sheep

carried on certain pastures.

The export of rams to the mainland declined as the graziers in Victoria and

the Riverina developed their own stud flocks, which considerably reduced the

income available to the Tasmanian graziers from this source.

The supply of labour available for pastoral pursuits was directly affected by

the discovery of gold in Victoria in 1851 and the cessation of the transportation

of convicts to Tasmania in 1853.

The events which occurred during the latter part of the previous period

tended to produce a more stable sheep population. With the election of the first

Parliament in Tasmania in 1856 the country settled down to steady development.

The sheep numbers oscillate about the calculated curve throughout this period,

the short-term oscillations being duc to the temporary influence of various factors.

The decrease in numbers about 1870 is associated with (a) the prevalence of

sheep scab, which necessitated the passing of the “Scab Act of 1870”; (b) the

prevalence of fluke in certain pasture areas; (c) the development of the rabbit

pest, which necessitated the passing in 1871 of “An Act to Provide for Destruc-

tion of Rabbits in Tasmania’; (d) the persistent fall in the price of wool which

dropped from 22d. a pound to 15d. a pound between 1862 and 1870.

(d) Fourth Period, 1925-1936

The upward trend in the population in this period is associated with the

improvernent in pastures and their management, together with the expansion of

the market for fat lambs. The area of top-dressed pastures has steadily increased.

346

In 1923/4 the total agricultural area manured with artificial manures was 193,453

acres; it had increased to 412,468 acres in 1936/7 with an increase of 14,000 tons

in the amount of artificial manures used. The area of top-dressed pastures

increased from 52,077 acres in 1929/30 to 191,928 acres in 1936/7. Improve-

ments of the natural pastures have increased their sheep-carrying capacity,

CoRRIGENDA

In my previous paper (Davidson, 1938, p. 141) the sheep population at the

end of 1838 should read 28,000.

THE MOUNT CAERNARVON SERIES OF PROTEROZOIC AGE

By D. MAWSON, O.B.E., D.Sc., B.E., F.R.S.

Summary

Mount Caermarvon is the highest point of a bold range of hills which forms the eastern flank of the

Flinders Range in the locality lying due east-south-east of Oraparinna Head Station. In that locality

exists a large unbroken block of Proterozoic sediments. Differential weathering has there brought

into strong relief the hard and soft members in the succession of strata, resulting in a series of

parallel ridges marking the hard beds. Mount Caernarvon is on the crest line of the most westerly of

these ridges which, as the beds dip regularly to the east, is the lowest (oldest) in order of deposition.

Looking eastward from the summit of Mount Caermarvon, other parallel ridges extend athwart the

view until, at a distance of about 5 miles, the low and nearly level plain leading to Lake Frome is

reached.

THE MOUNT CAERNARVON SERIES OF PROTEROZOIC AGE

By D. Mawson, O.B.E., D.5c., B.E., F.R.S.

[Read 13 October 1938]

Mount Caernarvon is the highest point of a bold range of hills which forms

the eastern flank of the Flinders Range in the locality lying due east-south-east

of Oraparinna Head Station, In that locality exists a large unbroken block of

Proterozoic sediments. Differential weathering has there brought into strong

relief the hard and soft members in the succession of strata, resulting in a series

of parallel ridges marking the hard beds. Mount Caernarvon is on the crest line

of the most westerly of these ridges which, as the beds dip regularly to the east,

is the lowest (oldest) in order of deposition. Looking eastward from the summit

of Mount Caernarvon, other parallel ridges extend athwart the view until, at

a distance of about 5 miles, the low and nearly level plain leading to Lake Frome

is reached.

Throughout a section meastired across the strike of these beds, as detailed

below, there was found to be a remarkable regularity in the dip of the beds and

no evidence of faulting. The average dip is about 28 degrecs, whilst the high

and low extremes of dip recorded are, respectively, 31 and 25 degrees. The

strike of “he beds, where undisturbed, is about 10° east (true).

At Jess than 3 miles northward from the Mount the beds are faulted and

twisted almost at right angles to their former alignment. To the south, the

undisturbed character of the block continues only for a few miles.

In view of the favourable features presented by this block, it has been

selected as an area for special study in connection with our investigations of the

Pre-Cambrian succession in the Flinders Range, which is the outstanding area

for Proterozoic rocks in South Australia.

In the following list of strata encountered in this section, the beds are dealt

with in order, from below upwards, and the thicknesses given in feet are the

reduced yalues of true thicknesses. The full thickness of the Mount Caernarvon

ereywackes at the base of the section was not ascertained for those beds extended

further west than the summit of Mount Caernarvon, which was the western limit

of the section. ‘he fact that the number 1 item on the list does extend beyond

the 100 fcet measured is indicated in the list by the plus sign attached.

The upper Hmit of the section was determined by the fact that beyond the

beds listed no outcrops appear near the line of section above the alluviated plain.

There is, however, no reason to suppose that the sequence does not continue below

the surface accumulations of the plain.

The accompanying line block illustrates the relation of the individual beds

to the surface topography.

dolomite beds exhibit “hieroglyphic” markings, others feature a thin

laminated (2 mm. thick) texture.

sandy bands suggests water-sorted tuffs. A 10-feet thick band of

sandstone forms the top of this section.

45 500 “t. of chocolate-coloured beds. This division is largely hidden beneath

soil but appears to be mainly chocolate shales. At 30 feet from the

base there are intercalations of thin (4 to 5 inches thick) bands of

dolomite. The upper 100 feet is reddish-chocolate-coloured and

becoming increasingly sandy above, finalising in thin-bedded, sandy

flagstones. Dip, 29° to the east.

These beds all lie at a lower stratigraphical level than those detailed in a

recent paper“ dealing with formations cxisting some 25 miles to the north-west

of Mount Caernarvon. No attempt will be made in this place to relate these

formations to those of the Parachilna locality or to discuss their significance, for

stich will come better at a later stage when the details of further critical areas

under review are published. It may be mentioned, however, that the deposition

of the lowest beds in this section was contemporaneous with some part of the time

occupied in the laying down of glacial and fluvio-glacial sediments in other parts

of South Australia.

The nature of the cryptozdonic and “hieroglyphic” markings of the dolomitic

limestones will be dealt with elsewhere.

The 10,711 feet of strata accounted in this contribution represents only a

portion of the depositions laid down in the Flinders Range geosyncline during

late Proterozoic time.

Iseilema

The discovery by C. E. Hubbard that Anthistiria membranacea, Lindl.

(1848) is the same as /seilema actinostachys, Domin (1915), necessitates the

following changes in the naming of our species as published in Trans. Roy. Soc.

Zoisia Matrella (L.) Merrill (== Z. pungens, Willd.) This small grass,

resembling Distichlis spicata, and collected by Prof. J. b. Cleland in damp places

near the Rocky River and Karatta, Kangaroo Island, has been provisionally deter-

mined as above by Mr. C. E. Hubbard, of Kew.—Coasts of Malaya, South India,

China, and the Philippines. Spikes about 1 cm. long; spikelets 25-3 mm. long.

CARYOPHYLLACEAE

Stellaria filiformis (Benth.), Mattf. in Fedde Repert., Betheft C, 148, t. vii,

figs. 1-8 (1938), instead of Drymaria filiformis, Benth. The change is made by

J. Mattfeld, on the ground that this plant has the characters of Stellaria (3 free

styles, a 6-valved cylindrical capsule and no stipules), whereas Drymaria, which

is almost entirely an American genus, has a single style surmounted by three

branches, a capsule usually ovoid or globular and opening in three valves, and

stipules.

This very slender little plant has only been found on the Murray and near

Ardrossan, Yorke Peninsula, in South Australia, and appears to be very rare,

but may have been overlooked on account of its insignificance. It is found

throughout temperate Australia,

THE RADIO-ACTIVITY AND COMPOSITION OF THE WATER AND

GASES OF THE PARALANA HOT SPRING

By KERR GRANT, M.Sc.

Summary

The general and geological features of the Paralana Hot Spring, which is situated on the eastern side

of the Flinders Range about 400 miles north-east of Adelaide, have already been described in a

paper presented by Sir Douglas Mawson to the Royal Society of South Australia (Proc. Roy. Soc. of

S. Aust., 51, 391, 1927). The present paper reports only the results of observations on its radio-

activity and gaseous content. These observations were made, in the first place at the spring, by an

expedition consisting of the writer (K. G.) and Messrs. Iliffe and Thompson, members of the staff of

the physics department of Adelaide University, which visited the spring in May of this year, and,

subsequently, in the physics laboratory of Adelaide University, upon samples of gas and water

collected at the spring and brought back for further examination.

THE RADIO-ACTIVITY AND COMPOSITION OF THE WATER AND GASES

OF THE PARALANA HOT SPRING

By Kerr Grant, M.Sc.

[Read 13 October 1938]

Pare XXI

The general and geological features of the Paralana Hot Spring, which is

situated on the eastern side of the Flinders Range about 400 miles north-east of

Adelaide, have already been described in a paper presented by Sir Douglas

Mawson to the Royal Society of South Australia (Proc. Roy. Soc. of S. Aust., 51,

391, 1927}. The present paper reports only the results of observations on its

radio-activity and gaseous content. These observations were made, in the first

place at the spring, by an expedition consisting of the writer (IK. G.) and Messrs.

Iliffe and Thompson, members of the staff of the physics department of Adelaide

University, which visited the spring in May of this year, and, subsequently, in the

physics laboratory of Adelaide University, upon samples of gas and water

collected at the spring and brought back for further examination.

The expedition left Adelaide by car on the afternoon of Monday, 23 May,

1938, and arrived at the old and now abandoned homestead of the Paralana Sheep

Station on Thursday, 27 May. The next three days were spent in collecting

samples of gas and water from the spring, which is about 24 miles distant from

the homestead, and in making such observations as were possible on the spot with

apparatus which had been brought for that purpose. This apparatus included

two electroscopes, each mounted on an ionisation-chamber with necessary

apparatus required for measurement of the amount of radium emanation con-

tained in the spring water (vide Appendix), and a Geiger-Muller electron-tube

counter which could be used for the detection of feeble sources of radio-activity

by means of their gamma ray activity.

As described by Mawson, the gas rises in a fairly continuous stream of bubbles

from a number of points, perhaps twelve or more in all, in the sandy bottom of

the pool. These points appear to be fairly definite in location, though the escape

of gas from any one may cease for a time and resume after an interval which

may range from a few seconds to several minutes. The gas was collected in

screw-top bottles by the usual device, namely, by inverting a wide-mouthed tin

funnel under water over the point from which the stream of bubbles issues and

inserting the upward-pointing neck of the funnel into the neck of a bottle which

had been previously filled with the spring water, the bottle being also supported

in an inverted pasition, The gas-bubbles entering the bottle gradually displace

the water, and when the bottle is nearly but not quite filled with gas, it is lifted

from the funnel and the screw-top mserted without permitting the mouth of the

bottle to rise above the surface of the water. The bottle is kept and carried

always in an inverted position, so that it is continually water-sealed. Even with-

out the water-seal there is no reason to think that any appreciable amount of gas

would enter or leave a bottle in which the top is screwed tightly home and, with

the water-seal, such escape is certainly impossible. These bottles had a capacity

of approximately one and one-third pints (760 c.c.) and the time taken for a

bottle to fill from a single stream of gas-bubbles was approximately half-

an-hour, though very variable. Assuming that twelve vents had this same produc-

tivity we get a daily (24-hour) output of gas of the order of twenty cubic feet

per day. It is possible, of course, that this output might be very greatly increased

by cleaning out the sand from the bottom of the pool and removing the huge rocks

which have fallen into it from the overhanging cliff. Judging by the sound of

bubbling, there was an issue of gas from a vent beneath the largest of these rocks

with an output larger than any of those in the open pools.

Radio-activity had previously been reported in the gas, though not in the

water, of the pool by Dr. C. Fenton, and confirmed by Mr. R. G. Thomas in a

sample sent by Dr. Fenton to Adelaide. The strength and character of the

radio-activity have not previously been definitely determined. Tested at the

Paralana homestead on the evening after collecting, the bottles of the gas showed

strong, those of the water much weaker but still definite radio-activity. The Geiger-

Muller tube counter was used for this first test. This instrument, which counts

the individual electrons liberated within the counting tube by gamma-radiation

passing through it, the number of these electrons liberated per second being

proportional to the strength of the gamma-rays, has always a natural or back-

ground count which has to be subtracted from the total count when a radio-

active source of gamma-rays is placed near the tube to give a figure determinative

for this latter.

This background count is due partly to the slight radio-activity always

present in the earth, in the air, and in the metal and other materials of tube and

accessory apparatus, partly to electrons liberated by cosmic rays. The count must

always be taken over a considerable interval of time in order to reduce the varia-

tions due to statistical fluctuations in the strength of the radiations. On a count

of 100 this fluctuation averages ten per cent., on 10,000 one per cent., ete. Only

when the count exceeds the background by a fraction definitely in excess of these

values can sound inference of the presence of radio-activity be made.

The background count of the counting-tube used on this trip was determined

in the physics laboratory and found to lie between 10 and 20 per minute; that

in the old Paralana homestead lay within the same range, though possibly some-

what higher than in Adelaide. ‘Lhe count at the spring itself, however, was

unmistakably higher, possibly three or four times as high. This high activity

was probably due to the continuous escape of radon from the spring and the

deposit of the products of its disintegration on the surrounding rocks, trees, etc.

When a bottle of gas from the spring was held within a foot of the counting-

tube the counts were invariably increased to a figure exceeding this background

by more than fifty per cent. The approximation of a bottle filled with the spring-

359

water to the same distance gave a smaller but still definitely significant increase

in the count. The radio-activity of the water thus put in evidence was such as

might be expected to result from radon gas (radium emanation) dissolved in the

water in consequence of the active gas bubbling through it. More accurate

measurements made next day at the spring indicated an activity in the water of

1,050 “Eran” units per litre (one “Eman” unit is 107° curie); in the gas of

7,800 “Emans” per litre.

An attempt was made to separate out any helium gas, which the spring gas

might contain, from the nitrogen and other common gases on the spot, by heating

the gas in contact with metallic calcium contained in a silica tube, a procedure

which has been successfully used for the purification of radon at the Adelaide

University. The attempt failed because it was found impossible in the open air

to heat the tube and its contained calcium with a plumber’s blow-lamp—the only

means available—to the temperature (600° C. or higher) at which it will combine

with nitrogen to form the nitride.

On return to Adelaide, Mr. ‘thompson undertook a series of systematic

measurements on the radio-activity of the gas dissolved in the water with a view

to ascertaining the rate of decay of its radio-activity, from which rate the nature

of the active constituent could be inferred. The measurements were made with

an ionisalion-chamber combined with an clectroscope, The apparatus was

standardised, in order to reduce these measurements to absolute value, by means

of solutiors prepared from standardised tubes of radium chloride solution supplied

to the writer by the Physikalische Technische Reichsanstalt, Charlottenburg,

Germany. ‘Lhe results of these measurements are as under:

Time (Day and Hour) Activity (in Arbitrary Units)

2320 - 7.6.38 - - - 262

1615 - 9.6.38 - - - 185

11442) - 10.6.38 - - ~ 168

If the alpha-ray activity—which is what is measured by the method

employed-—is due only to a single species of radio-active element, then the law of

radio-active decay with time is exponential, i.c., the activity decays by the same

fraction in the same time—and the plot of the logarithm of the activity against

the time is a straight line.

As the graph of Fig. 1 shows, this relation is obeyed very closely by the

measurements here recorded. ‘he slope of this graph gives the so-called “half-

period” o/ the radio-active element in question, and this half-period as obtained

from the graph is 3°82 days, agreeing very well with the accepted value 3°825

days for radon (radium emanation). This close agreement makes it improbable

that any active element other than those belonging to the radium series occurs in

360

the spring water. Nevertheless, the extrapolation of the graph back to the time

at which the observation was made on the water at the spring would give an

activity considerably less (by over 20 per cent.) than the value actually obtained

there, and this discrepancy could conceivably be attributed to the presence of the

short-lived thorium emanation. It is much more likely, however, that it arises

merely from variability in the radon content of water drawn from different places

in the pool and at different times, and hence there is little risk in assuming that

the only active constituent of the spring water is radium emanation and that this

is present to the extent of approximately 1,000 Eman units per litre of water.

TIME

Fig. 1

The graph shows the relation between the activity of the gas contained in

the water of the spring and the time. The logarithm of the activity is plotted

(on an arbitrary scale) in order to exhibit, from the strictly linear character

of the graph, the law of geometrical decay (i.e, that the activity decreases in

the same ratio in equal intervals of time) characteristic of a single species of

radio-active element. The slope of the graph indicates that the activity is

reduced to one-half (logarithm by 0-30) in 3-82 days, this value agreeing

satisfactorily with the accepted value of 3-825 days for radon gas

(radium emanation).

Although the waters of most thermal springs, in which, presumably, the water

has ascended from considerable depths, contain more or less dissolved emanation,

few contain so much as the Paralana Spring. In a list of fifty European Spa-

watcrs given by Professor Stefan Meyer in his authoritative work on Radio-

activity, there are only seven of which the radio-activity exceeds a value of

1,000 Emans per litre. This unusually high radio-activity of the Paralana Spring

361

is probably not unconnected with the fact that in the rocks of the area in which the

spring is situated there are frequent occurrences of uranium-bearing minerals.

THe NAruRE or THE SPRING GASES

No complete analysis of the gas which bubbles up through the spring appears

to have hitherto been made. The most usual constituents of gases collected from

bore waters in Australia are nitrogen, carbon-dioxide, methane, hydrogen and

oxygen, w:th the first of these usually greatly exceeding all the others.

The Department of Chemistry of the South Australian Government very

kindly undertook to make an analysis for these gases, the result of which is as

follows: Nitrogen, 88:1% ; carbon-dioxide, 11-9%.

Since, however, the inert gas, helium, commonly, and, in lesser quantity, its

congener, neon, occasionally, are found in the gases associated with thermal

springs, and since in this case the probable occurrence of helium is also indicated

by the radio-activity of the spring—tfor alpha-rays are nothing but electrically

charged helium atoms—an analysis for helium or other inert gas was undertaken

in the physics laboratory.

The problem to be solved in this analysis is to get rid of all gases other than

the inert by chemical action or absorption. After trying with very little success

three different modifications of a method involving the passage of electrical dis-

charge between electrodes of magnesium in the vessel containing the gas the

method first described by Soddy (Proc. Roy. Soc., London), viz., by heating

metallic calcium in a pyrex or silica tube was resorted to. The calcium combines

with the nitrogen at temperatures above 600° C., with the hydrogen at about 250°.

This method proved very successful, although to obtain a complete “clean-up” of

all active gases, and especially of the hydrogen, it was found advantageous to

supplement the calcium process by absorption in charcoal cooled with liquid air.

The apparatus and details of procedure employed in this analysis are more

fully described in the Appendix. After the “clean-up” was accomplished the

residual gas was forced into a small glass capillary fitted with electrodes and the

spectrum produced by an electric discharge between these examined, in the first

place usually with a direct-vision spectroscope, and subsequently by photography,

using a larger spectroscope and camera (pl, xx1).

Provided complete clean-up had been accomplished, not a single line could

be seen in the spectrum other than those characteristic of helium; with a less

perfect clean-up, hydrogen, especially the strong red line (Ha), was seen to he

present and, at a still earlier stage of the cleaning-up process, the bands of

nitrogen were also in evidence. Only on one of the many spectra examined could

any lines be seen which, though very faint, might possibly indicate the presence

of a trace of neon. If present at all in the spring gases, the percentage is less

than one-hundredth of one per cent, and such an amount might well be due to

contamination of the sample by atmospheric air.

Precise measurement of the percentage of helium was not easy because of

its very small amount—the volume extracted from 200 c.c. being little more than

362

one-tenth of a cubic centimetre. Three separate determinations made with the

gas collected in the 4-gallon iron drum gave the following values: 067, °053,

‘047, with a mean, therefore, of 0-056 per cent.

MINERAL CONTENT oF SPRING WATER

An analysis of the water for its mineral content has been made by the Assay Depart-

ment of the School of Mines. The results are as given in the table, in which, for the

sake of comparison, the figures given for the analysis reported in Mawson’s paper are

also given.

Tt will be seen that the only significant difference in the two analyses is in respect of the

magnesium, and even this is little more than one grain in the gallon.

Since the above analysis was confined to salts of the alkali and alkaline earth metals

and small quantities of the heavy metal might possibly have been present—though

improbably, because the presence of hydrogen sulphide which would have precipitated

these as sulphides was perceptible by its odour—I asked Dr, Allan Walkley, of the Waite

Institute, who has recently been using the “Polarograph” method of detecting zinc,

copper, and other heavy metals in solution, if he would be so good as to examine the

Paralana water by this method, This he has done and his report on the analysis is as

follows:

“Residue on evaporation oe se 0-1

Chlorides sh ate sty ve 0-03%

Copper, zinc, nickel, cobalt, iron and

manganese —— less than 1 p.p.m.

The brown precipitate present in the original sample was not examined.

Karlsbad and Joachimsthal are, in Y per litre.

Cu Bi Pb Zn Ni

0-2-30 0-2-0°6 0-1-1 0-7-65 0-02-8,”

It will be seen that Dr. Walkley’s determination of the total solid dissolved, wiz.,

0-1. per cent., agrees perfectly with that made in the assay department of the School of

Mines, and that the total amount of all heavy metals from jron and zine onwards amounts

to less than four parts per million, a practically negligible content.

The temperature of the water in the spring pool was given by Mawson as 144° F.

Numerous measurements made at different places in the spring by the present party

gave valucs as a rule much below this figure, but varying from place to place, and

363

especially with the depth to which the thermometer bulb was immersed in the water or

underlying sand, The highest temperature (140° F.) was recorded in the sand beneath

the large overhanging rock underneath which the outflow of water and gas seemed to be

greatest.

The depth of sand in and surrounding the open pool and the dense growth of

bulrushes in the creek below it rendered quite hopeless the intention af measuring the

amount of water issuing. Our opinion was that the amount issuing in the open pool

was today probably much less than the figure given by Mawson, vis., 1,000 gallons per

hour, The apparent diminution may well be duc to the decrease in size of the open pool

which Mawson gives as 20 yards but which is now not more than 5, so that the majority

of the vents and fissures in the bed-rock by which water and gas issued in 1927 are today

covered by sand and debris.

APPENDIX

Metiuop AXpd Resu.ts or MEASUREMENT or RADIO-ACTIVITY OF

Sprinc WATER AND GAS

The a-ray activity of samples of water and gas from the spring were measured with

an ionization chamber and gould leaf electroscope.

APPARATUS

; I

i 364

The electroscope A consists of a small brass cylinder, the gold leaf being attached

to a polished brass support projecting into the interior of the cylinder and insulated from

it by a sulphur bushing, The ends of the cylinder are provided with two small glass

windows for observation. The electroscope is supported immediately above the ionization

chamber B, a large well-sealed tin having a central rod insulated from it by a sulphur

bushing and provided with two side tubes for the circulation of gas through the chamber.

C is a calcium chloride drying tube, D a glass “bubbler” and E a rubber bulb provided

with valves allowing gas to pass in one direction only.

PROCEDURE

100 c.c.s of the spring water were introduced into D and the air in the chamber

circulated through the apparatus—bubbling through the water sample. This circulation

was continued for some minutes and a reading of the a-ray activity taken with the

electroscope, This procedure was repeated over a period of an hour or more, until the

electroscope gave a constant reading indicating that the system had reached equilibrium.

The rate of discharge of the electroscope was determined as follows: The gold leaf was

observed with a telescope having a micrometer eye-piece with a scale 100 divisions in

length. A suitable positive voltage (180 volts) was placed on the gold leaf which is

connected to the rod of the ionization chamber, the case of the electroscope being con-

nected to the chamber and the negative terminal of the H.T. battery. The telescope was

then adjusted so that one edge of the gold leaf was just beyond one end of the scale, The

battery connection to the rod was broken and the time for the gold leaf to traverse the

scale determined with a stop-watch.

The gas from the spring was measured in the same way, 100 c.c. being introduced

into D by displacement of water, D being inverted and the stopper with each outlet tube

closed by a piece of rubber tubing and a clip inserted under water.

STANDARDIZATION OF ELECTROSCOPE

A standard solution containing 4-00 x 10° grms, radium was prepared and intro-

duced in a flask similar to D. The side tubes were sealed and the flask left for at least

seven days to ensure that the radio-active disintegration had reached equilibrium. The

flask was inserted in place of D and the a-ray activity measured as before,

CORRECTIONS

Although the ionization chamber was large compared with the rest of the apparatus

it does not contain all the gas, and the volumes of the variotts components must be

measured in order to find what fraction the ionization chamber represents. The volume

of water is equivalent to an amount of air equal to its volume x the solubility of the

radio-active gas at the temperature at which the readings were taken. The gas was

shown to be radon (see below), and its solubility was obtained from tables.

Since the ionization chamber represented 93% of the total volume and the volume

of the rest of the apparatus varied only slightly, this correction reduces to a constant’

multiplier (variation <1%), and may be neglected in the calculations for relative

activities.

The electroscope readings have to be corrected for natural leak, #.¢., the rate of dis-

charge of the electroscope in the absence of radio-active material, Since this was at least

several hours and the normal reading at most a few minutes, this correction is quite small

and can be measured accurately.

The electroscope was tested for linearity, i.c., as to whether the time of discharge

was proportional to the radio-activity as follows. Readings were taken on a 10 mgm.

and 1 mgm. standard radium tube, placed in exactly the same position some two feet from

the chamber. After correcting for natural leak, these indicated a departure from linearity

All readings of the rate of discharge could be obtained to within 1%.

Standardizations with two separate standard solutions agreed to about 79%, and con-

stitute the main source of error. (Maximum error, < 10%.)

Thus a solubility of about 13% of the gas in the spring water would account for all of

the radio-activity of the water. -13 is the solubility of radon in water at 60° C.

with comparison spectra of helium plus mercury (top) and hydrogen (below).

The most prominent lines in the Paralana gas spectrum are those of helium (notably

6563 AU. and 5875 A.U.). The hydrogen lines (notably the strong red line

6563 A.U.) are also present. The mercury lines fie., 5461 AU. and 5769-90 A.U.)

are duc to the mercury present in the collecting tube. There is also a faint band

system, probably due to residual nitrogen. There is no trace of the neon spectrum.

SOME RECENT VOLCANIC DEPOSITS AND VOLCANIC SOILS FROM

THE ISLAND OF NEW BRITAIN IN THE TERRITORY OF NEW GUINEA

By J. S. HOSKING, Waite Agricultural Research Institute, Adelaide, South Australia

Summary

A suite of volcanic deposits resulting from the recent eruptions at Rabaul, the capital of the

Territory of New Guinea, together with a series of soils developed upon similar parent materials,

from the Island of New Britain, has been examined.

All the samples examined fall within a characteristic grouping with respect to the mechanical

composition of the mineral fraction.

While the recent deposits may contain up to 5 per cent. of soluble salts, the soils, despite their

possible proximity to continuous solfataric or fumarole activity are particularly free from salt owing

to the intense leaching effects prevailing under the heavy rainfall conditions.

The deposits and soils vary from slightly acid to neutral in reaction, and the latter are notable for

their natural fertility.

SOME RECENT VOLCANIC DEPOSITS AND VOLCANIC SOILS

FROM THE ISLAND OF NEW BRITAIN IN THE TERRITORY OF

NEW GUINEA

SUMMARY

A suite of volcanic deposits resulting from the recent eruptions at Rabaul,

the capital of the Territory of New Guinea, together with a series of soils

developed upon similar parent materials, from the Island of New Britain, has

been examined.

All the samples examined fall within a characteristic grouping with respect

to the mechanical composition of the mineral fraction.

While the recent deposits may contain up to 5 per cent. of soluble salts, the

soils, despite their possible proximity to continuous solfataric or fumarole activity

are particularly free from salt owing to the intense leaching effects prevailing

under the heavy rainfall conditions.

The deposits and soils vary from slightly acid to neutral in reaction, and the

latter are notable for their natural fertility.

INTRODUCTION

New Britain, the largest of the islands of the Mandated Territory of New

Guinea, is a long crescent-shaped island about 300 miles long and averaging about

60 miles wide lying about 4° to 6° south of, and roughly parallel to, the equator.

With the exceptions of the Gazelle and Willaumez Peninsulas the Island is little

known and remains practically unexplored, since, apart from the low-lying

coastal regions, it is mostly mountainous and heavily forested. Alienated land

seldom extends for more than 10 miles inland from the coast, and the greater

part of the settlements occur on the low coastal strip extending between the aforc-

mentioned peninsulas.

A considerable proportion of the cultivable soils of the island of New Britain

is of volcanic origin, and a number of these soils have been received from time

to time for examination in this laboratory from the Department of Agriculture

of New Guinea.

The recent eruptions in the neighbourhood of Rabaul towards the end of

May, 1937, permitted of fresh volcanic material being collected by the Department

for comparison with the soils derived from similar materials.

Trans. Roy. Soc. S.A., 62, (2), 23 December 1938

367

The soils received have been from Talasea on the Willaumez Peninsula, and

from Rabaul and Kokopo on the Gazelle Peninsula, The volcanic deposits were

all from Rabaul from the two craters of Vulcan Island and Matupi Island in

Blanche Bay, on which the harbour of Rabaul is situated.

The rainfall at Talasea is 171 inches, of which 78% falls in the summer six

months, while at Rabaul it is 88 inches and at Kokopo it is 86 inches, with

summer proportions of 71% and 63%, respectively. At no time of the year are

drought conditions likely to prevail, and leaching of the soil may be expected to

be active during at least six months of the year.

The staple industry of the island is the cultivation of coconuts and the manu-

facture of such coconut products as copra, desiccated coconuts and coir fibre.

Apart from the establishment of a small coffee industry and the successful grow-

ing of kapec, little has been done in the cultivation of other crops. The Depart-

ment of Agriculture is, however, investigating the possibilities of growing cocoa,

tobacco, cinchona, peanuts and other tropical crops.

Reference may be made to the report of Stanley (1922) for an account of

the geology and vulcanology of the island.

DESCRIPTION OF THE RECENT DEPOSITS

Seven samples of the recent deposits were collected from in and around

Rabaul shortly after the recent eruption, hey represented two samples of dust,

one of which had been protected from rain, from Vulcan Island; four samples

of mud and ash, two of which were hardened or compacted, while a third had been

considerably washed and sorted by the action of torrential rains, from Matupi

crater; and finally a composite sample of the total depth of deposit at Rabaul.

The deposits are fairly uniform in colour; those from Vulcan Island being

of a grey-white shade, while those from Matupi are somewhat darker and vary

from slate-grey to grey-black.

They are extremely light and floury, being composed mainly of particles of

the dimensions of fine sand and silt. From their mechanical analysis they appear

to vary in texture from sandy loams to loams bordering on clay loams. The dust

deposits from Vulcan Island and the washed and sorted material fall within the

former class, while the hardened mud and compacted ash from Matupi belong

to the fatter class; a mud layer from Matupi is intermediate in texture. From

their general physical reactions and a comparison with similar deposits from New

Zealand, however, they may more correctly be described as silty loams and

silty clays.

Only in the sorted sample is there any appreciable concentration of pumiceous

gravel and coarse sand; all the samples are, however, highly abrasive.

Analytical data for the deposits are given in Table I.

DESCRIPTION OF THE SOILS

Thirty-nine soil samples, representing two profiles from the vicinity of

Rabaul, two profiles from the subdistrict of Kokopo, and five profiles from the

district of Talasea, have been investigated, and the analytical data are given in

Tables I and II. Apart from the Rabaul profiles, one of which is from under

virgin forest and the other from under a Kunai grass cover, the soils have been

taken from plantations either under or cleared for cultivation.

The soils have developed on geologically recent deposits consisting of

volcanic showers of ash and mud and andesitic, rhyolitic or pumiccous sand, and

despite the high leaching effect of the rainfall are still extremely immature in

their development. From an examination of the stone within the profiles and

from a consideration of the mechanical analyses of the soils, it is apparent that

a number of showers have been deposited one on top of the other in each of the

areas. At least three distinct layers, in which the material varies from distinctly

pumiceous to andesitic or rhyolitic in character, are to be observed in the profiles

from Talasea. In the profiles from Rabaul and Kokopo, the layering is by no

means as definite, but, nevertheless, apparent. The pumiceous type of parent

material dominates the soils from Rabaul and Kokopo while the vitreous andesitic

or rhyolitic types are more pronounced, particularly in the lower layers, from

Talasea; gravel and stone are a very characteristic feature of the latter profiles.

The soils from the two centres, while showing little variation in their

chemical characteristics, show some marked differences in their physical and

mechanical composition, and the general profile from each district is best described

separately.

The profiles from Rabaul and Kokopo (see fig. 1) consist of from 9 to

colour varies somewhat from grey-yellow to almost white, the lightening in colour

becoming more pronounced with depth, and the texture is more definitely sandy.

There is only a small concentration of pumiceous stone in the profile, although

it may become somewhat pronounced in the lower and more sandy layers.

Layering is a much more definite characteristic of the soils examined from

Talasea ; there is a very definite break from the loamy textured layers to extremely

coarse sands at about 24 inches. ‘he soil profile, which is illustrated in figure 2,

medium clay to sandy loam. Below 24 inches the soil consists of extremely sandy

deposits of volcanic ejectamenta, somewhat variable in colour although a yellow

shade, increasing in intensity with depth, predominates.

While the surface layer of the soils to a depth of about 12 inches is practi-

cally free from stone, about 6%, principally pumiceous, occurs in the second foot.

Pumiccous and other stones reach a maximum concentration (up to 30%) in the

third or fourth foot, where lumps of pumice, up to several inches in diameter,

may be found. Below 36 inches the lumps of pumice decrease in size and

amount, and their place is taken by less scoreaceous and smaller fragments

of more vitreous material. In the lower layers these latter fragments together

with glassy material and large grains of heavy minerals are present, to the virtual

exclusion of pumice within the gravel fraction.

Like the fresh deposits all these volcanic soils, apart from the most sandy

samples, have a distinctly silty feel and may similarly be described as silty clays

and silty loams.

MECHANICAL COMPOSITION

The samples of both the volcanic deposits and the soils have been mechani-

cally analysed, and while the individual figures for clay and silt are given in

Tables I ard II, the complete results are summarised in Tables III and IV.

The major characteristic is seen to be a high very fine sand plus silt content,

which amounts to from 50% to 60% in the deposits and soils from Rabaul and

Kokope. The change in the sandiness of the soils with depth reflects the nature

372

of the deposition of the parent materials; the coarser deposits having settled first

and being covered in turn by medium and finer-grained materials.

In figure 3 the mechanical analyses of the samples have been plotted on a

distribution triangle. In addition the area of the triangle within which the compo-

sition of soils developed on similar parent materials from Mount Gambier in

South Australia‘) and from New Zealand (Grange et. al. 1932) may be found,

has been shown for comparison. All the deposits and soils fall into a charac-

teristic grouping with respect to the mechanical composition of the mineral

a definitely more pronounced silt content in relation to the clay, than those of a

more basic, andesitic or basaltic, origin. The pumiceous nature of the deposits

from the Vulcan Island crater and soils from Rabaul and Kokopo and the more

basic nature of the soils from alasea are indicated by their position in the

triangle. There is a very much more marked scatter in the case of the former

than the latter soils which lie practically on a continuous curve.

A more detailed analysis, by sieving of the sand fractions, was carried out

for a number of the samples and the summation curves and probable frequency

distribution curves derived therefrom, down to the lower limit of the silt fraction,

are shown in figure 4. A maximum concentration of particles with a grain size

around the fine sand-silt limit is characteristic of all the samples, and most pro-

the weight per unit volume (apparent specific gravity) of the surface soils, and

dust samples from Vulcan Island, emphasise their powdery nature, while the high

values for the water-holding capacity of the pumiceous samples are indicative of

their extreme porosity.

The very low to negligible volume expansion of the recent deposits shows

that the fraction determined as clay represents in reality the final stage in

mechanical disintegration of the original material rather than a final stage in

chemical weathering, and should strictly speaking be included with the. silt.

Following the operation of soil-forming processes, however, true mineralogical

clay species, with the normal property of swelling, are formed.

CHEMICAL CHARACTERISTICS

The deposits and soils have been examined by the usual standard methods

of chemical analysis, and the values, for the various constituents determined, are

given tn detail in Tables 1 and 11 and summarised in further tables of the text.

SOLUBLE SALTS

The recent deposits were examined for soluble salts by extracting 200 gms.

with one hitre of distilled water. Owing, however, to the approximate saturation

of the aqueous solutions obtained from the deposits containing the larger amounts

of calcium sulphate, it was necessary to determine the total calcium sulphate by

extraction with standard hydrochloric acid. The results are given in Table VI.

The salt content is seen to vary from 4% to 5% in the more acid deposits,

to about 1 % in the slightly alkaline Matupi mud layer. The rapidity with which

the salts may be leached from the deposits is indicated by the very low content,

less than 0°19, in the sample which has been subjected to the action of water.

Calcium sulphate (gypsum) and sodium chloride constitute the bulk of the

soluble salts, although potassium and magnesium salts are also present. While

the calcium sulphate is a natural result of the fumarole action during volcanic

activity, the high content of sodium chloride is undoubtedly due to contamination

with sea-water. At the bottom of Table VII the ionic concentrations are expressed

in terms of the probable salt species present.

Despite the close proximity of solfataric and fumarole action the soils are

particularly free from salts, due to the intense leaching under the prevalent heavy

rainfall conditions.

376

REACTION

The reaction of the samples was determined by means of the glass electrode,

using a ratio of sample to water of 1 to 5, and the results are summarised in

Table VII.

Despite the presence of sulphur dioxide and hydrogen sulphide in the gaseous

emanations during the volcanic activity the deposits contain no free acid, but it

may be observed that the deposits containing the larger proportions of calcium

sulphate show a slightly acid reaction. With a removal of the salts there is a

change to slight alkalinity.

The soils themselves all show slightly acid to neutral reactions. There is

little more than 1 pH unit variation from profile to profile, and within the indi-

vidual profiles there is generally a change from slight acidity in the surface layers

to neutrality or faint alkalinity at the lower depths.

The soils are particularly well supplied with organic matter down to a depth

of from 12 to 24 inches, but below the surface the content falls off markedly and

progressively in descending the profile.

A remarkable uniformity in the value of the carbon to nitrogen ratio through-

out the whole range of soils is to be observed. Only in the two surface samples

377

from Rabaul, where ratios of 15-8 and 12°4 are found, does the ratio vary more

than about 0°5 unit from a mean value of 10-3.

A small proportion of organic matter, about 0°1%, derived no doubt from

contact with the atmosphere, is present in the volcanic deposits.

The contents of both phosphoric acid and potash, as determined in the

standard hydrochloric acid extract (see Table 1X), are very satisfactory from

the point of view of plant nutrition.

The deposits and subsoil samples show a fairly uniform content of phos-

phoric acid, about 0-1%. In the surface soil samples the content is much higher

and the excess amount, over and above that extracted from the recent deposits,

appears to bear a close relationship to the organic matter content.

Some variation is seen to occur in the content of potash, not only of the soils

but also of the deposits, which in general show somewhat higher concentrations

than the former. Within the soil profiles there is no general variation with depth,

a similar range in the content of potash being experienced in each layer.

fiith year. From an early age, Meyrick took an interest in the Lepidoptera and

soon made the smaller forms his particular study, his first published note appear-

ing in 1875.

In 1877 he took up a scholastic post at Sydney, and a few years later a

similar post at Christchurch, New Zealand. During these years he found an

astonishing variety of micro-lepidoptera, and made thorough and intensive

collections. On his return to England in 1887 he became assistant master at the

public school at Marlborough, and from thence came a great succession of papers

dealing with these smal! moths from all regions of the world.

During his active work it has been estimated that he described some 20,000

species, besides many genera and families. ITis outstanding work was probably

the “Handbook of British Lepidoptera,” in which he placed the classification on

a sound basis.

He was clected an Honorary Fellow of this Society in 1898, and our Trans-

actions contain many papers dealing with his own groups.

Not only the Society, but entomology in general and Australian entomology

in particular, are poorer by the loss of this authority, for there are few younger

workers of his calibre to continue the much-needed work still to be done.

CHARLES ALLEN SEYMOUR HAWKER, M.A., M.ELR.

The late Capt. C. A. S. Hawker was born on 16 May 1894 at “Bungaree,”

Clare, South Australia, which estate was established by his grandfather, the

Hon. G. C. Hawker, M.P., who came to Australia in the “Lysander” in 1840.

Capt. Hawker was educated at Geelong Grammar School and Trinity College,

Cambridge, where he took his M.A. degree.

He erlisted in 1914 in the Somerset Light Infantry and saw service in

France and Belgium. Thrice wounded, he was invalided with the rank of

Captain and returned to Australia, where he took up pastoral pursuits. Me was

Vice-President of the Returned Soldiers’ Association in 1921, and a member of

the Commonwealth Board of Trade in 1927. In 1929 he was elected to the Com-

monwealth Parliament for Wakefield, which seat he retained until his untimely

death. During this time he held the position of Minister of Markets, of Repatria-

tion, and became the first Minister of Commerce.

He was elected a Fellow of this Society in 1924, and although he did not

take a very active part in the mcetings of the Society, his loss will be deeply felt.

The worst air tragedy of this country, on 25 October, has not only deprived us

of a valued member, but the country is the poorer for the death of a great

statesman and patriot who has carried on the highest traditions of a distinguished

family.

JOHN SUTTON

The late Mr. John Sutton was elected a Fellow of the Society in 1922. He

passed away on 22 November in his seventy-fourth year after a short illness.

Mr. Sutton took up the study of birds seriously at the age of 53, and after

the death of Mr. F. R. Zietz, when Dr. A. M. Morgan became Honorary

Ornithologist at the S.A. Muscum, he joined him as Assistant Honorary

Ornithologist. During his 15 years work in this position he put the large collec-

tions of birds on a sound and efficient basis of cataloguing, personally registering

about 15,COO specimens.

On the death of Dr. Morgan he became Honorary Ornithologist.

From 1922 until he retired in March last he was Honorary Secretary of the

South Australian Ornithologists’ Association. In 1927 he joined the editorial

committee of the “South Australian Ornithologist,” and to his enthusiasm and

ability the success of this publication was largely due.

Mr. Sutton was the author of many scientific publications on birds and their

habits, printed in the “Emu” and the “South Australian Ornithologist.”

Until recent years Mr. Sutton was a frequent attender at our meetings.
