SUMMARY

In this paper nineteen. species of planls are described as new to the State,

Details are given of the extended distribution of an additional eighteen species.

INTRODUCTION

The first part of this paper consists of an alphabetical list of plant species

considered new to South Australia, Of these, thirteen aré exotics now regarded

as established here, the remaining six are native species previously recorded near

the South Australian borders.

The second part of the paper consists of an alphabetical list of plant species

previously recorded here from restricted or widely differing localities, and the list

gives extended occurrences of nine exotic and nine native species.

Specimens of all the species listed are lodged in the Herbarium of the Waite

Agricultural Research Institate (ADW).

RECORD OF NEW PLANT SPECIES

Arum lL, (Araceae)

Perennial herbs with tuberous rootstocks. Leaves net veined, petioles sheath-

ing at the base. Inflorescence a dense flowered simple spadix supported at its

base by a leaf-like or coloured bract, the spathe, the upper part of the spadix

withont flowers, the flowers all unisexual female below, the upper ones sterile;

male above, the upper sterile. Perianth segments absent, Ovary 1-celled. stigmas

sessile.

Arum italtcum Mill., Gard. Dict. ed. VILL 2 (1765).

An erect glabrous perennial, 50 cm, tuber depressed globular 3-4 am diam.

Autumn leaves small, hastate uniform green, later leaves long pctioled, sagitate,

while patterned above the larger veins, about 15 cm long. Spathe 20-30 cm erect,

pale greenish yellow. Fruit L em fleshy, scarlet, the fruiting spike standing naked

and showy after the leaves have withered. Flowering in November-December.

A native of southern Europe and a garden escape here.

Fistablished at Mylor and Williarnstown.

long, gaping when mature, 2-3 Howered, breaking above the glumes but not

between the florets which fall together when ripe; florets pale or dark when

ripe, and sparsely or densely covered with long hairs; lemma 15-20 mm Jong, the

upper Horets smaller, lower foret awned, the upper florets with or without awns,

awn stout, 5 cm long, almost black,

A weed of cereal crop now widespread but nowhere as common as A. faiuit,

the common Wild Oat, from which it is readily separated by the spikelets falling

as a group and not readily separating. In England at least A. Iudoviciana is a

seriuus weed of cereals on heavy soils in the southern counties, and in South

Australia it has been collected from the better rainfall areas of the wheat belt,

Now established at Kybybolite, Melrose, Roseworthy, Turretfeld, Yongala

and in the Adelaide suburbs.

Black, Fl, S.A. ed. 1 (1926) 426,

An intricate shrub, the young branches pale with white leaf bases, the older

branches grey; the leaves 28-3 mm long, 1-14 mm broad trigonous in section,

the leaf edges and keel finely ciliate; flowers subsessile in the upper axils, solitary

or mre often forming terminal heads of 3-6 Howers; bractecles 2, seariaus,

keeled, 9 mm long including a mucro of 1 mm, scarcely united; receptable 12 mm

of which 7 mm is adnate to the ovary and the upper 3 mm is free and hollow;

sepals avate 5 x 22 mm and terminated by an awn Y mm long, petals 7 min,

acute, bright pink; stamens 30-40,

lt may be separated trom C. tetragena by the receptuble above the Ovary

being hollow and by the shorter leaves, and from C. imeolucrata by the absenve

vf an involucre of bracts surrounding the fluwers.

Although mentioned in the first edition of the Flora of South Atistralia as

likely to veeur in this State, no account was given in the second edition, The

species has now been collected from several localities in the far north, Mt.

Moulden, between Mt. Moulden and the Blyth Range and at Mt. Vivian.

Cassia glutingsa DC., Prod, 11 (1825) 495; Benth., Fl, Aust, 2 (1864) 286; Black,

F). S.A. ed. 2 (1948) 430.

Glabrous shrub with yiseid branchlets and pods. Leaves with 5-6 pairs of

oblong leaflets 8-15 mm ling and 2-3 mm wide, often with a short gland between

each of the lowest pairs of leaflets, Flowers 2-6 in an umbel, bright orange

yellow, relatively large, the petals 10-15 mm Jong. Pads with a varnished appear-

alice When fresh, 3-6 em Jong and 1 cm broad,

This species is listed and briefly described in the Flora of S.A. as likely io

decur in our far north. It is widely spread hut not common in northern Aus-

tralia, and has been collected from near the nickel mine at Mt. Davies, Tomkinstn

Range,

Cyperus arenarius Retz. Obs. 4 (1786) 9.

A perennial 15-30 em high with extensive, somewhat brittle, horizontal

thizames, covered with fibrous sheaths, no tubers are formed; from the rhizomes

arise vertical leafy shoots; leaves grass-like, distinetly grey-green in colour, chan-

nelled abave but not keeled below, the iargins often ineurved, 2 mm wide

and 10-20 em lang with loose sheaths; stems erect, terete, longer than the leaves.

the inflorescence subtended by about 3 leaf-like bracts the shortest of which

is 1-2 em Jang and the longest 7 em; inflorescence a compact umbel 10-15 mm

in diameter of about 12-14 spikelets; the spikelets 5-6 mm long and consisting

of 10-12 flowers, the flowering ghimce 3 mm long speckled brown; style 3

branched, stamens 3; nut abovoid, planoconves, 1 mm Jong,

This species is firmly established and is proving a difficult weed in a garden

on red sand at Port Augusta. It was reputedly brought in with soil filling, but

other established areas have not yet been found. It would appear to be a new

record for Australia.

Datura

The nomenclature of the genus Datura has been confused in South Australia.

Datura tatula may be considered y variety or calour form only of D. stramoninm

and. it is not usually maintained as a species. It should at least be reduced. in

rank from that of a species. Almost all specimens previously identified as D.

metel are in fact D. inoxia which has not previously been recorded for South

Australia. The only authentic specimen of D. mete! seen so far has been a double

flowered purple form, grown as an ornamental plant in a suburban garden, It

is doubttul whether D. mefel is in taut naturalised in South Australia.

Datura ferox L. is naturalised and should be added to the flora.

Most species of Datura contain powerful alkaloids and all the intraduced

species are declared noxious weeds.

The following key to the species in South Australia is offered.

This species could be added to the Flora as of limited occurrence in Suuth

Australia,

Prostrate or ascending annual, smooth, with long hairs near the ligule,

Spikes mostly 2-6 (5-6 in our specimens) flat, 4-9 cm long and 3-5 mm wide.

It is readily separated from Eleusine tristachya which has fewer (1-3), shorter

{1-2-5 cm). broader (5-10 mm) spikes, and is often purplish in colour. It is

now sparingly established at Whyalla.

to an awn 1-2 cm long. Lemma lanceolate, 3 nerved, very scabrous, with a

flat awn 5-10 cm long.

A native to Europe, this grass has become a bad weed on the range country

uf California and is a potentially bad weed here. The sparse foliage and very

long harsh awns make it of very little use as a pasture plant. It does not appear

to have been recorded for Australia before and was well established at Black

Springs, 10 miles south of Burra.

INTRODUCTION

Since an carlier record (Brookes, 1957) several specics of scale insects

(Coecoidea) that have become naturalized in South Australia, have been recog-

nized. These include tour that have not been reported previously from Australian

records,

A complete synonymy for each species has not been attempted; it has been

selected to give the following citations, if available: the original description;

the first recorded occurrence in Australia; the synonyms used in the Australian

literature and the currently accepted reference to the genus.

Specimens were examined after being treated by either of two methods: the

first involved partial maceration in 10 per cent aqueous potassium liydroxide,

staining with acid or basic fuchsin, and mounting in a synthetic neutral medium,

such as “Sire”; the second, clearing in lacto-alcohol and mounting i Berlese’s

fluid.

in Sydney.

Steinweden (1946) in describing the species P. hydrangeae stated that this

insect has frequently been misidentified in the past as P. floccifera (Westwood),

from which it is clearly distinct. Since none of the specimens identified by

Froggatt is now available for re-examination, it is possible that they too were

misidentified. Specirnens submitted for identification by the Department of

Agriculture of New South Wales were identified in 1960 by the author as

P. hydrangeae.

tralia in October, 1956, when it was found on a few peach trees growing in an

irrigated citrus orchard at Mypolonga. This occurrence involved a light infes-

tation of young laterals and a heavy infestation of older branches. Subsequently,

almond, apple and pear trees in thirteen additional orchards were found to be

infested, Following an intensive eradication campaign, two simall infestations

recurred in 1961 and 1962.

Small, isolated outbreaks of San José scale were discovered jn 1960 at Mount

Cambier in mature apple trees in three home gardens, and at Aldgate in the

Advlaide Hills, where 4 few old apple trees in a commercial nursery were very

lighily infested.

In February, 1961, an extensive outbreak was found on mature pear trees

in the irrigated orchards of Renmark, about thirty properties being involved.

Siuee then it has been identified an apple, plum, peach and walnut.

Smaller outbreaks of San José scale were feomnd on pear at Waikerie in

1961 and on peach at Lyrup the following year, At Waikerie the infestation

which was traeed from imported nursery stuck bus spread to many trées in a

newly planted area.

ALBIAN AMMONITES FROM FOSSIL CREEK, OODNADATTA,

SOUTH AUSTRALIA

BY R. A. REYMENT

Summary

Fifteen species of ammonites, of which one is new, are recorded from the South Australian part of

the Albian sequence in the Great Artesian Basin at Fossil Creek, 30 miles west-north-west of

Oodnadatta. Thirteen of the species are heteromorphs. They are assigned to Labeceras s. str., L.

(Appurdiceras) and to Myloceras. The non-heteromorphic species belong to Falciferella.

Connections with New Guinea are confirmed and relationships with the Albian of Portuguese East

Africa pointed out. The descriptive presentation is supported by some simple bivariate biometric

analyses. Remarks on the nekroplanktonic dispersal of heteromorphic ammonites are made. The

currently accepted correlation of the beds containing heteromorphs on the international zonal scale

is confirmed.

SUMMARY

Fifteen species of ammonites, of which one fs new, are recorded from the

South Australian part of the Albian sequenee in the Great Artesian Basin at

Fossil Creek, 30 miles west-northavest of Oodnadatta. Thirteen of the species

are heteromorphs. They are assigned to Labeceras s. ste, L. (Appurdicerus)

and to Myloceras. The non-heteroimorphic species belonyz to Faloiferella. Con-

nections with New Guinea are confirmed and relationships with the Albian of

Portuguesa East Africa pointed out. The descriptive presentation is supported

by some simple bivariate biometric analyses, Remarks on the nekroplanktonic

dispersal of heteromorphic ammonites ure made, The currently accepted cor-

relation of the beds cantaining heteromorphs on the international zonal scale

is confirmed.

INTRODUCTION

It is some 60 years since the first Albian ammonites were described from

South Australia by Etheridge (1508). Later work on the Queensland exten-

sions of the Great Artesian Basin disclosed the presence of a multitude of forms,

largely heteromorphic; these could be tied up with a few earlier discoveries,

including a small but important collection from New Guinea. The occurrence

of certain species of the genera Prohysteroceras and Mortoniceras permitted

incorporation of the Australian occurrences in the international zonal scheme.

This was indeed fortunate, as it had not been possible to base correlation on

the unique uncoiled forms, at Jeast not at that time.

There seems to have been a Inll in interest in the South Australian Lower

Cretaceous, until the exploration for ofl in the Great Artesian Basin once again

provided the necessary incentive to further work. Up to the early fifties the

South Australian ammonite faunas were badly known and it might have been

thought strange that there was so little agreement with the sequence in Queens-

land. However, it is now possible to demonstrate complete faunal agreement

between the two areas.

The material described and figured in the present paper has been deposited

in the collections of the Geological Survey of South Australia, Adelaide,

LOCATION OF THE AREA

The area lies at about the intersection of 27° south latitude and 134° east

longitude. The fossils were obtained from exposures in the Fossil or Wool-

diidge Creek, which lies roughly 30 miles west-north-west of Oodnadatta,

The ammonites were collected by the following people: Dr. R. O. Brunn-

schweiler (1955), Dr. H. Wopfner, Mr. A. Hess and Mr. D, Seott (1956), as

well as officers of the Geological Survey of South Australia, among them Mr.

J. Johnson.

DESCRIPTIVE SECTION

Family LABECERATIDAE Spath, 1925

(Syn. Aleteceratidae, Whitehouse (1925), Myloceratidae, Spath (1939) )

The encompassment given by Wright (1956) in the Treatise of Tuvertebrate

Paleontology is here observed. The family is then considered to comprise

heteromorphs which are at first coiled in an open spiral, but later whorls may

be in contact, the shell terminating in a hook. The aperture is provided with

weak to moderately prominent, rounded lappets. The whorl section is moder-

ately to fairly strongly compressed, All genera have fine, branching ribs that

cross. the venter, U:bilical or ventrolateral tubercles, or both, occur. The

suture consists Gf bifid saddles and smallish bifid lobes.

Genus Lasecrras Spath, 1925

Type Species—Laheceras bryani Whitehouse, 1926.

Description.—Rather small shells with an open spire of a few whorls, fol-

lowed by a curyed shaft and a final hook, with the aperture usually fieing inward,

The ribs are fine, slightly sinnous and Jean forwards; occasionally they bifureate.

Umbilical tubercles may occur on the shaft and hook, as also ventrolateral

tubercles.

Age—aAlhbian.

Subgenus Lasuceras

Remarks,—I., (Labeceras) is considered to comprise forms lacking ventro-

lateral tubercles.

1926 Laheceras papulatum, Whitehouse, p. 228, pl. 36, fig, 4; pl. 30. figs, 3a-b.

Desctription.—This species is characterized by the dense ribbing and its ten-

dency, on the bady chamber, to weaken, become less dense and to develop

tubercles on the umbilicus, The whorl section is inflated oval, the venter is

smoothly rounded, The last 4:5 em up to the Jast suture have 33 ribs, counted

on the venter (a rib density of «= 7-3/cm).

Remarks, —There are genuine differences between this species and L, (L.)

bryani Whitehouse with respect to the ribbing. The specimen studied has

part of the altered shell material preserved on the umbilical area — here umbilical

tubercles occur, whereas on the other (figured) side, on which the shell is

missing, tubercles aré only suggested. It would therefore seem that the presence

or absence of tubercles on the body chamber is largely a matler of preservation,

althogh infraspecific variation certainly plays a part.

Description —None of the specimens available is complete. The species is

characterised by clavate umbilical tubercles on the body chamber, from which

the ribs proceed in bundles of twos and threes, Two fragments may be from

the septate part of the shell; these are also provided with umbilical tubercles,

but these lie further down on the dorsolateral shoulders, The whorl sections of

these two smaller fragments are subquadrate, whereas that of the body chamber

is almost round.

Material—Three specimens, M 1440, M 1441, M 1442.

Remarks.—Whitehouse (1926, p. 229) thought that the seplate part of the

shell of this species might not be tuberculate. The evidence of the present

material, although not absolutely conclusive, suggests that the contrary may

be true. It is still not possible to give a picture of the suture line; however, the

fragment of the body chamber also has the last septal surface preserved. From

this it may be interred that the central lohe is narrow, the external saddle very

broad, the first lateral saddle is narrow, but not as narrow as the ventral lobe,

and the first lateral saddle is also broad. This accords well with the general

form of the labeceratid suture. The ribbing of the form referred here by

Glaessner (1958) appears coarser ard the ridges formed by the saddles on the

septal surface are wider than our matcrial, Nevertheless, the original figures

of Etheridge (1909, p, 49, figs. 7 and 9) indicate variability with respect to

costation. The East African material figured by Spath (1925) agrees closely

with the Australian.

were then subjected to regression analysis. It is worth mentioning that the

whor] dimensions do not increase regularly and there are frequent slight diminu-

tions shown by the largest specimen. In text Fig. 1 a plot of logy (breadth)

The logarithmic transformation is necessary as the measurements are non-linear,

thus indicating differential growth. The correlation coefficient between the

transformed variables is 0-926, which is highly significant.

PL 1, Fis, 3-4

1926 Labeceras compressum, Whitchouse, p. 228, pl. 36, fig, 5; pl. 39, fies, Sa-b,

Description.—This species is characterised by the compressed whorl section,

the numerous, thin ribs, which lean slightly forwards on the shaft of the body

chamber. but straighten up on the hook thereof, and the rather tight bend of the

ervok. The rihs may bifurcate at the dorsolateral margin or in the outer third

of the Hanks, The rib density of the body chamber studied is e=7-7/em. The

lappets run from the dorsolateral shoulder to the beginning of the vuter third

of the flanks. The suture line has a relatively broad external lobe, a broad

external saddle with a rather well developed median sublabe, a broad first

lateral lobe and a first lateral saddle of about the same width as. the first

lateral lobe.

Material—Two specimens. M 1415, M #443.

Remarks.—Unfortunately, the photograph of the holotype supplied by White-

house: (1926, p. 29, fig. 5a) is indistinct so that the details of the ribbing cannot

be made ont. However, the distinctive development of the lappets is clear,

as also the compressed whorl section,

Holotype.—A vomplete specimen, M 1444 and M 1445, fisured in Pl. 1, Fig, 5.

Diugnosis—A species of L, (Labeceras) with the following characteristics:

Whorl section strongly compressed, sigmoidal ribbing, simple and bifurcated,

leaning slightly forward, aperture not turned in towards shaft.

Description —The coiling is aucyloceratid, the tip of the shell lying only

about 1 mm, from the shaft. The body chamber takes up just less than one-half

of the total shell length (= 0-47 of total lenvth). The shell heightens rapidly

(see text Fig. 2) during the first part of its Jenzth and thereafter the increase

is less rapid. Height increase ceases around the hook of the shetl, where pevinds

of decrease in height also occur, The rib density is «= 6-5/em. The ribs are

slightly flexed, they widen slightly outwards. Most ribs bifureate either at the

dorsolateral margin or at the outer third of the fank. but simple ribs alse ovcur,

The aperture is not directed towards the shaft, but faces instead outwards, The

suture line is typical of Labeoeras. Maximum length = 62 mm.

Muterial—One complete specimen. This specimen is in twu parts, the one

an almost complete monld, lacking the first part of the shell, the other partly the

impression of the shell, but bearing the first part of the shell,

cation may ocour. Some ribs bear ventrolateral tubercles,

Description—This species is characterised by its subquadrate to circular

whorl section, and the stout, only occasionally bifurcated ribs, which lean for-

wards, about every filth of which is provided with a strong, spinate ventro-

lateral tubercle, The ribbing appears to hecome denser on the body chamber.

Genus MyLocenss Spath, 1925

(Syn, Aleteceras, Whitehouse, 1926, Flindersites, Whitchouse, 1926),

Type Species —Crioceras ammonoides Utheridge, 1909.

Description,—Shells larger than Labeceras s. 1. with the spire either crio-

ceratid or ancyloceratid and more closely coiled than Labecerus; at some stage

of development some whorls are in contact. The aperture does not face inward

to the same degree as in most Labeceras. "The whorl section varies from strongly

compressed to strongly depressed. Ventrolateral tubercles may occur.

Remarks. —The differences considered by Whitehouse (1926) to be of generic

importance in separating Myloceras, Aleteceras, and Flindersites are so slight

as to be hardly of specific importance. In the present connection, therefore, the

procedure adopted by Wright (1957) is adhered to and all are grouped under

Myloceras Spath.

Description.—The whorls partly embrace. The body chamber has a depressed

becoming depressed while the shell is still septate. The septate whorls bear

occasional ventrolateral tubercles (on about every sixth or seventh rib), The

later septate part lacks tubercles, There are both simple and bifurcated ribs,

simple ribs being most common on the hody chamber. The shell wall is almost

3 mm. in thickness. A complete final suture is shown in Text Fig, 3.

Remarks—The miaterial here described agrees with the specimen from

Aramac, Queensland, very well. The depressed whorl section of the body

chamber serves to distinguish the species well from other Myloceras,

Biometric Analysis—The ontogeny of the whorl section was studied by

plotting breadth of whorl against height of whorl (Text Fig. 4). There is

obvious non-linearity in the data and it may be concluded that the growth

rates for breadth and height change differentially with respect ta each other,

There is not sufficient material to permit 4 regression analysis.

pressed but by about a diameter of 45 mm. it is almost subquadrate. Judging

trom the materia] at hand there also appears ta be an ornamental chanye during

the ontogeny in that the early part of the shell has slightly flexed ribs, these

tending to become straighter, sharper, and slightly reclined at more advanced

growth stages, There seems to be some variability concerning the point at which

the ventrolateral tuberculation becomes apparent. The tubercles of the figured

not always be easy tu pick it out, It seems likely that Whitehouse based his

new species tardicostatum on the inner whorls of plectoides.

of the non-tuberculation of the outer whorls of the latter and the “different”

Description —This very large species is characterised by the clavate yentro-

lateral tubercle, which. seem to disappear on the last parts of the body chambers

of very large specimens and the sharp, though low, ribs, which may be almost

straight to slightly flexed. After one turn the whorls are in contact. At a

diameter of 19 mm, the ornament consists of single ribs, every fourth of which

is provided with a spinate tubercle. Here the rib density is roughly «= 8/cm.

A specimen with a radius of 46 mm. is somewhat more compressed than might

be expected, but this may be ua normal ontogenetic feature; it appears to have

been slightly crushed, At this stage each rib bears an almost clavate tubercle

and rib bifurcation is of frequent occurrence. Larger fragments are more

Biometric Analysis.—Pcrusal of the plot of the data on whorl height and

breadth in Text Fig. 7 indicates some departure from linearity, but this is not

of the order as to necessitate the logarithmic transformation. The figure also

indicates further support for the identifications of the fragments here made, as

deviating specimens would show up by falling outside the path of ontogenetic

development,

and Whitehouse (1926), and the accompanying descriptions, fails to bring

forth criteria of sufficient importance as to warrant specific separation of ammo-

noides and orbiculum. Thus, both are reported to be compressed, to he more or

less ovoid in section, to be densely ribbed with flexed costae that are straight

on the venter; only occasional ribs bear tubercles, and the ribs do not bifurcate at

the tubercles.

Remarks.—This species is the most richly represented one in the collection,

Unfertunately, yery few of the fragments permitted measurements. M. davidi

and M. ammonoides are not easy to hold apart, particularly in crushed speci-

mens, as both are compressed and have much the same tvpe of ornament. More-

over, one of the characteristics considered specific for M, ammonoides, namely,

the bundling of ribs at the ventrolateral tubercle, has been observed to oceur

in M. davidi, together with rib division. In fact, on the basis of the information

offered by the present material, it would seem that the whorl section offers the

only more or less relitble way of holding the two species apart. The two

specimens figured by Glaessner (1957) from New Guinea are typical of the

species.

ON THE DISPERSAL OF HETEROMORPUIC AMMONITE SHELLS

Growth of the heteromarphic shell. Changes in the coiling of a cephalopod

shell depend ou fluctuations in the allometric relations governing growth of the

same, Jor the purpose of simplilying the following discussion it will be taken

that growth occurs by mearis of two centres, one controlling the dorsal part of

the shell, and one its ventral part. If the growth rates of the dorsum and venter

we equal (isometric vrowth), a straight shell results (for example, straight

nautiloids). In ammonites, however, the growth rate of the yenter is asually

many times greater than that of the dorsum, and coiled shells with embracing

whorls result—the greater the ventral growth rate, the greater will be the

degree of involution of the shell. Hence, the position may be summarised by

saying that the growth of the venter is always positive allometric with respect

to the growth rate af the dorsum, apart from the special case of equality of the

42 K. A. REYMENT

aorta rates, A heferomorphic shell will result when the two rates of growth

uctuate. Tenee, in Labeceras the ventral rate of growth is initially slightly

greater than the dorsal rate of growth, the difference being so slivht, that the

whorls are never in contact. This stage is followed by a period of isometric

srowth, atter which a return to much the same growth differences us during

earlier ontogeny is made, For Myloceras the growth differences ure, for abarit

the fivst whorl, similar to thase pertaining in Labeceras, after which a period

of inevease in the positive allometric relationship takes place. Here, the whorls

are just in contact with each other. This growth stage is followed by a period

of isometric growth, after which a reversion to the earliest pattern occurs,

It is well known that the spiral of the ammonite shell may be described

by the Jogarithmiec spiral. That is: r=aci*, where a is a constant, r the shell

radius, » the angle of the spiral, and y is a factor which determines the shape

of the curve. The factor y thus decides whether the shell will be involute,

evolute or with the whorls not in contact (Llaarlinder, 1952). During part ot

the growth of both Laheceray and Myloceras the shell describes a logarithmic

spiral. Hewever, particularly in connection with the formation of the Imyly

chamber this is not so. ‘This is the most important difference between hetero-

morphic ammonites (excluding those in which the logarithmic spiral is folluwed

at all growth stages—in a sense these are not genuine heteromorphs) and

normal ammonites.

The Relationship Between Shell Shape and Shell Dispersal —iw this section

the importance of the shape of the shell with respect to nekroplanktonic dis-

persive possibilities is reviewed and some formulae for the yolume of certain

idealised shell types given. According to the results obtained by my investi-

gations on Laetors in the distribution of fossil cephalopods (Reyment. 1958)

the orthoconic type of shell is one with excellent Hoating capabilities; hence,

one Jikely to be widely spread nekroplanktonically. The volume of an idealised

orthocone is given by the simple expression: V= }4r°h, where r is the radius

of the hase and fh is the height of the shell. In this kind of shell the maximum

expusure of surface area is achieved and the maximum relative uplift results,

Far dead shells the buoyaucy is decreased by the weight of the body chamber,

it could be shown experimentally (Reyment, 1958, p. 122) that the body

chamber of an orthocone must exceed half of the total shell length it a shell

is ty sink, A rough expression for the mass of the aragonite In a conical shell,

assuming a thickness of 1mm. is M = 0°98 x (r*,hy—7%h.), where 1) and 1m are

the differences in racing due to wall thickness and fy and fs are the correspand-

ing differences in height. Similar expressions may be derived for shells of ellip

tical cross section (the baculitid type).

Tor cviled shells the effective volume depends on the degree of involution

vf the shell, the lesser the degree of evohttion the greater the elfective volume,

The effective volume of a cuiled evolute shell the whorls of which are just in

contact is given by the following expression (kindly derived for me by Dr.

ALBIAN AMMONITES FROM OODNADATTA, SOUTH AUSTRALIA 33

This will also apply to heteromorphic shells as long as the logarithmic spiral

is followed, Generally, the combination of the properties of straight shells and

evolute shells met with in heteromorphic ammonites, as in Labeceras and

Myloceras, indicates high huoyancy properties, owing to the maximum utilisation

of the entire length of the cone in the effective volume. Consequently, it is to

be expected that heteromorphic ammonites will be good floaters in the nekro-

planktonic state (Reyment, 1958, p. 172), depending | naturally on the length of

the body chamber, For Labeceras oodnadattaensis sp. nov. the bady chamber

makes up 47 per cent of the total shell length, which is within the bounds

required in order for the empty shell to float. In Fig. 9a-b the nekroplanktonic

floating positions for Labeceras and Myloceras are shawn.

B

Fig. 9 a, Floating position for Labeceras; b, Hoating position for Myloceras.

Kuidence for Nekraplanktonic Dispersal—This is of two kinds, geographic

and sedimentologic. The relatively wide geographic distribution of some of

the species treated in this paper is suggestive, Firstly, we have the expected

wide distribution of species in the Great Artesian Basin—practically all of the

forms among the heteromorphic ammonites treated by Whitehouse (1926) in

his monograph also vecur in the South Australian material. Secondly, there is

the occurrence of thesc heteromorphs in New Guinea, amongst them the forms

recorded by Claessner (1958), including Labeceras crassum Spath and Mylo-

ceras davidi Whitehouse. Finally, there is the important occurrence of Labeceras

erassum Spath and Myloceras axonoides (Etheridge) in Portuguese East Africa.

The buoyant structure of these shells suggests that possibilities of wide-ranging

oceanic transport, as has been observed for the shells of Nautilus (ef Reyment,

1958),

34 R, A, REYMENT

The nature of the sediment in which the ammonites occur is of the calcareous

tidal mud type, such as that forming in the Bahamas Islands area today (cf.

Reyment, 1958), and also in the Jurassic deposits of Solnhofen and Holzmaden,

Germany. The drifting shells finally fastened in the shallow water calcareous

sediment.

The actual living place of the ammonites was probably in the sea nearby

and cven further out, but this can, of course, only be a matter of speculation,

The only certain tact is that the places of occurrence of the ammonite shells do

not represent the area in which they actually lived.

STRATIGRAPHIC CONCLUSIONS

All ammonites are of Albian age and are to be correlated with the varicostm-

eyyatoriale zones of the standard English Gault succession (Spath, 1925), and

H, Wopfner of the Geological Survey of South Australia. Dr. Ludbrook also

kindly arranged publication of these results. The photographs were taken by

Mr, L. Kutnar, formerly of the Department of Geology, University of Stockholm.

tu connection herewith Mr, Kutnar devised a way of photographing plasticene

casts of ammonites.”

* All ammonites were coated with ammonium ¢hloride prior to photographing. Tt is,

however, not pussible to achieve a suiwoth distribution of this substance on plasticene casts

af wharls, which usually meang that the cast must be photographed without preparation,

Mr. Kutnar found that by first chilling the cast and then spraying with an acrylate fixing base

(Zapon plastic lacquer—used for fixing pencil drawings) a surface conld be produced on which

the ammonium chloride will fasten satisfactorily.

COILING AND FORM IN SOUTH AUSTRALIAN LABECERATIDAE

COILING AND FORM IN SOUTH AUSTRALIAN LABECERATIDAE

(ALBIAN; CRETACEOUS)

By BR. A. REyMentr®

[Read 9 April 1964]

SUMMARY

Observations are presented on the mode of eniling and the shell form of

some typical labeceratid ammonites from the Albian of Fossil Creek, near Ood-

nadatta.

There has been a recent awakening of interest in Lower Cretaceous hetero-

morphic ammonites. Wiedmann (1962) has published a rather far-gaing revision

vf many heteromorphs, including Labeceratidae, which he prefers to see as a

subfamily of Anisoceratidae. The purpose of the present note is to present

certain observations on the mode of coiling and shell form, particularly of the

apertural region, of a few typical laheceratids, selected from a large collection

of ammonites from South Australia, the taxonomic examination of which is the

subject of the foregoing paper.

The ammonites derive from a limestone in Fossil or Woolridge Creek near

Oodnadatta, South Australia.

It is not here proposed to enter into any form of phylogenetic discussion.

Suffice it to say that the writer is largely in agreement with Wiedmann’s analysis

of Anisoceratidac and related groups,

In order to assist the representation of the ammonites approximate sterco-

scopic photographs were made. Shadows tend to reduce the clarity of stersv-

scopic pictures of fossils. In an attempt to minimise the development of shadows

an electronic flash apparatus, mounted to the camera, was used (film Kadak 23

DIN). Coating with sal ammoniac gave unsatisfactory results owing to the

excessive reflection from the pure white surface produced. Better results were

obtained by using medium grey poster colour, Specimens are deposited in the

museum of the Geological Survey of South Australia.

Labeceras crassum Spath,

may appear planispiral. The stereopair in Pl. 2, Fig. 2a-b, show the form of

an almost complete specimen, and the nature of the aperture. The body

chamber begins at the point marked by an arrow in Pl. 1, Fig. 5. It is here

worth noting, that although Labeceras mostly has the aperture directed towards

the shaft, L. oodnadattaensis sp. nov. (Reyment, 1964) has the aperture directed

outwards.

Fig, 1 shows the plot of shell length against shell height. We observe that

these two variables are not linearly related; that is, whorl height and shell length

do not increase regularly with respect to cach other. The correlation coefficient,

computed from the Jogarithmically transformed measurements, is 0-9728, which

is highly significant.

units are (mm x LQ).

Myloceras davidi Whitehouse

TL. 1, fig. 3u-b (stereopair); pl. 2, fix. la-h (stereopair)

The specimen figures in Pl. 1, Fig. 3a-b, and Pl. 2, Fig. la-b shows the form

of the uncoiled part of a shell, including the aperture. The shell height in-

creases at first on the body chamber and then ceases to increase towards the

aperture. The plot of shell height against shell length is shown in Fig. 2; it

will be observed that there is some departure from an even growth relationship.

The correlation coefficient, computed from the logarithmically transformed

variables, is 0-6671, which is significant on the 1 per cent level.

Myloceras ammonoides (Etheridge)

PL 1, fig. la-h (stercopair). fig. 2a-b (stereppair); fig. 4; pl. 2. figs. 3-5.

This specimen shows well the spiral coiling of the early part of Myloceras

(Pl. 1, Fig. 2a-b; Pl. 2, Figs. 3, 5); this is not so clearly apparent in all species.

The specimen consists of the three initial whorls=the shaft and the hook are

missing. The whorls are barely in contact and in places do not touch (PI. 1,

Fig. la-b—space between dorsum of last whorl and venter of penultimate whorl

in the upper part of the specimen). The plot of shell length against shell height

in Fig. 3 shows an almost completely regular increase relationship to exist

between the two variables, The correlation coefficient, computed from logarith-

mically transformed observations, is 0-9579, which is yery highly significant,

REMARKS

The scattergrams of length and height of whorl suggest that one might

expect some sort of differential growth relationship between these variables.

The regression equations for each species were computed. to vield for:

Labeceras erassum: y = 6-76x"-44;

Myloceras davidi: y — 67-61x9 =";

Myloceras ammonoides: —y = 0-28x"")"

We have here the interesting result that the coiled whorls of Myloceras

ammonoides grow almost isometrically with respect to length and height of shell,

whereas the uneviled parts of Labeceras crassum and Myloceras davidi grow

in some kind of allometric relationship. :

Another interesting feature of the present analysis is that log length and

log height of shell are highly correlated for the shaft and crook of L. crassum

and for the whorls of M, ammonvides, but less strongly correlated for the shaft

and crook of M. davicdi,

rhynchus robustas from Sigenus lincetus (Cuvier and Vilonciennes }.

Figs, 1-5

Telesentiy Van Cleave, 1923; Colvan, LGN,

Host and Locality--One male and two female specimens collected by F. A,

Ballantyne, Oct., 1962, from the small intestine of Anguilla reinhardtii Stein-

dachner at Moggil Creek, Brisbane, Australia (specimens sent for identification

by Dr. J. Pearson, Dept, of Parasitulogy, University of Queensland).

Description—The length of the trunk of the male is 4-0 mim, and its maxi-

mum width in the middle of the trunk is 0-6 mm. The length of the females is

5-1-5-6 mm. ond their maximum width in the anterior half of the trunk is 0-65-

1-00 mm. The anterior region of the trunk is armed with numerous rows of

posteriorly directed spmes which extend for about one-third of the way along

the ventral surface. They are about 25-30 » long. The introvert of the male is

almost cylindrical; it; length is 0-72 mm. and inaximum width 0-14 min. The

maxiroum length of the introvert of the female is 0-78 mm. and the maximum

width 0-18 mm. The introvert is armed with 16 longitudinal rows of 23-26

hooks per row. The size and shape of some of the hooks is shown in Fig. 3.

The hooks on the anterior two-thirds of the introvert are largest and possess

rooting processes, The mast posterior hook of each longitudinal row is slightly

larger than those immediately anterior tu it. The difference in the size of the

dorsal and ventral hooks that is found in T. exiguis (von Linstow, 1901) and

in T. tenuicornis (Van Cleave, 1918) is not noticeable in the Australian specimens.

Although the body wall is thick, the outer epidermal layer itself seems to be

thin and easily distorted. The receptaculum is 1:2-1-5 mm. long and double

walled. The lemnisci are ag loug us or slightly longer than the receptaculuim.

The testes are ellipsoida] and about 0-3 mm. long; they lie almost one bebind

the other. The cement glands are long pyriform and pressed closely together;

their bumber was not able to be determined, The uterus is long and the vaginal

cummplex consists of twa bulbs. No genital spines were observed in the female

and only four in the pasteriur region of the male. The eggs are spindle-shaped

(535-54) p long and (10-13) » wide, and the female aperture is subterminal,

Systematic Positiou—The generic position assigned to these specimeiis is

nol altogether satisfactory. "They closely resemble species of the genus Telosentis

Van Cleave, 1923, but the female lacks genital spines, the presence of which

is a generic character. Golvan (1960, p. 159) says that the genital spines of

Telosentis arc fragile. This being so, | prefer to place them in the genus Telo-

gentis rather ihan create another genus within the family Rhadinorhynchidae

to. contain them,

The specimens differ from (1) T. moalini Van Cleave, 1923, the introvert of

which is armed with 12 longitudinal rows of 20 hooks and (2) T. exignus (von

Linstow, 1901) armed with 12 rows of 16-18 hooks. They are closely related to

T, tenuicornis (Van Cleave, 1918), the introvert of which is armed with 10-14

rows of 26 hooks. The introvert of the Australian specimens, however, possesses

more longitudinal rows of hooks than T. tentiicornis (Van Cleave, 1918, Plate

(11 B) and the spines on the anterior region of the trunk are relatively smaller

but far more numerous than those of T. fenuicornis as shown by Van Cleave

(1915, Plate IIT, Fig. 3). For these reasons they are regarded as a new species,

Host—One male and four female specimens were collected from the intestine

of the fish, Siganus lineatus (Cuy. et Val.), Cuallector Dr. J. Pearson (University

of Queensland ), June 2, 1956.

Locality—Heron Is., Queensland.

Description—The specimens show marked sexual dimorphism, the females

bemg about two and u half times as long as the males. The trunk of both sexes

is stout and curved yentrally to some extent in the anterior region. Posteriorly

it tapers gradually, Two lateral lacunae show up clearly in the body wall of

each of the specimens.

The trunk of the male is 15 mm. Jong and its maximum width—in the middle

of the trunk—is about 2. mm, A cylindrical introyert arises somewhat ventrally

from the anterior region of the trunk, Compared with the size of the trunk the

introvert is small, ‘Lhe armed part is 0-75 mm. long and 0-25 mm. wide, and

there is a short unarmed section about 0-08 mm, long. The former bears 14

longitudinal rows each containing 12-13 hooks per row. The posteriorly placed

hooks are smallest, The trunk is without spines. The receptaculum is double-

walled, 2-2 mm. Jong and 0-3 mm. wide. The Jemnisci are short and sac-like, The

testes are ellipsoidal and 1-2-1-5 mm. long, They overlap slightly, There are

four cement glands that are arranged in pairs und that arise at different levels.

The genital opening is terminal,

The trunk of the female is 28-37 mm. long and about 3-5 mm, wide in the

mid-region, The fully extended introvert is cylindrical, 0:9-1-0 mm, long and

about 0:3.mm. wide. There is in addition a short unarmed section 0-05-0-08 mm.

long. The introvert is armed with 14-16 longitudinal rows each of 12-14 hooks

per row. A double-walled receptaculum is 2-4-2-5 mm, long and 0-35 mm, wide,

The lemnisci are stout and sac-like and about as long as the receptaculum. The

female genitalia are about 4-5 mm. long and the anal aperture is sub-terminal.

Ripe eggs are (100-115) «long and (22-29) » wide and have polar prolongations

of the middle shell.

Systematic Position

These specimens from Queensland closely resemble Neogorgorhynchus

aspinosus (Fukui and Morisita, 1938) from the fish, Teuthis fuscescens. The

mtrovert of N. aspinosus according to Fukui and Morisita (1938) and Yamaguti

(1939) is armed with 17-18 longitudinal rows of 16-19 hooks per row while

that of the specimens from Siganus lineatus is armed with 14-16 rows of 12-14

hooks per row, The introvert of N, nudus (Harada, 1938), the only other species

in this genus, is armed with 14 longitudinal rows of 24-25 hooks per row. For

these reasons the specimens from Siganus lineatus are regarded as new and

because they are stout are given the specific name robustus.

INTRODUCTION

‘The nematodes described in this paper were collected by the Queensland

Institute of Medical Research, and sent to the University of Adelaide for exami-

nation by Dr. M. J. Mackerras, then of that Institute. I am very grateful tu Dr,

Mackerras for the opportunity pravided. Among these fresh and well-preserved

specimens it has been possible to identify one previonsly described species, and

two new species, for one of which a new genus, Purarugopharynx, is propused.

The material is plentiful, and it has been possible to measure ten mature

specimens of each sex for éach species; these measurements are given in Table 1.

The length of the vestibule and of the oesophagus is taken in each case from

the anterior end of the worm to the base of the structure,

The material received came from seven specimens of Protemnodon rufo-

grisea (all of which were parasitised in the oesaphagus as well as the stomach)

and one specimen of P. bicolor, with nematodes in both oesophagus and stomach,

All the hosts were from Logan Village, Queensland.

extending nearly to tips.

Posterior end of female narrows distal to vulva, tail hardly tapering, ending

in blunt point. Eggs about 100 p by 50 p.

The species resembles those of the genus Oesophagonastes in the shape of

the oesophagus, in the position of the associated structures, and in the tvpe of

bursa, Il is distinguished by the longer and more definite buccal capsule and

the form of the dorsal rays, as well as by the presence of an “accessory bursa”;

this latter structure is, however, present in O, leptos Mawson (in press).

Habitut—R, Helms’ speciniens were growing im a sandy place: the more

vigorous plants of the other collectors might have heen gathored from richer suil.

Characteristies—This variously appearing form, whiel: I treat as a distinct

species, bears a superficial resemblance to Pé indivisus Renl (= Pt. comphre-

noides Moq,, sin Mitt, Bot.StSammlg. Miinehen, 3:38, 1959). J. M, Black (in

schedulis). however, had already drawn attention to the most evident differ-

ences; “Differs from T. gomphrenoides in the branching hairy stem and want of

aciite tips in inner segments,” Besides, in Pt. indivisus the bracts and especially

the bracteoles are decidedly less tapering — they cannot be called awned there

The indumentum of the perianth is finer and considerably denser, the glabrous

tips of the tepals are shorter, Further differences concern the struature and the

proportions of inner flcral organs, particularly as regards the cupula, showing a

free ring only in P#, incivistis. There is, therefore, no close relationship between

these two easily distinguishable species,

Very young inflorescences of the new species resemble the corresponding

stages of Pt. manglesit (Lindl) Foy.Mucll. in their habit (colour, indumentum),

A blunt, naked and distinctly visible apex of the perianth-segments is a charac-

teristic feature not only of the above form, of P/, indivisus and Pt. manglesii, but

of some other species as well; yet they cannot be confused, The conspicuously

acuminate bracts and bracteoles represent an additional and noteworthy charuc-

teristic found also in a few other species (sc. 4: 80, 1961), From these,

however, the taxon in question is sharply separated.

Name—The plant is named in honmw of the well-known, distinguished

hotanist, J. M. Black (Flora of South Australia), who had dealt with this form

(in sehedulis) forty years ago, It was first defined by him as a varicty

Caristatum’) of ‘Trichinttum exaltatum’, then as “Urichinium beekerianwm’. One

annotation reads “appearing a new species”, but finally he misinterpreted it as

eas semilanatiwm Lindl, which is, by wo means, conspecific with Pe.

Material—The description is drawn up from a series of specimens differing

its habit and maturity. R. Helms’ plant (AI) 962 16 157), selected as holotype

becuse of its age, measures 22 cm to the top of the inflorescence and has more

than a dozen spikes more or less undeveloped. The Adelaide isotype resembles

the holotype in appearance and maturity; it consists of seyeral stems (11:3 to

19 em), apparently detached from one piece vf rhizome and each carrying, up

to & immature spikes. S$. A. White's specimen from Dalhousie (28 em) with

3 mature and 5 younger spikes is better developed, and the inflorescences carry

a greater number of fowers. S$, A, White's second sheet (AD 962 15 190) can-

sists oF two parts (35 and 26 em long, 3 to 4 mm thick) of stouter stems with

five and one spikes, respectively, and a slender stem (26 em) with one hall-

developed spike; it bears J. M. Black’s annotations and figures on the attached

label, The third paratvpe (AD 962 15 188) seems to be somewhat doubtful at

first sight. The scrappy material of a big and branched plant measuring 40 cm

in length and 7 mm in diameter does not carry any spikes; besides, the measure-

ments viven by J. M, Black on the shcet do not quite agree with those I ascer-

tained, However, a separate cover attached to the sheet contains two immature

spikes matching the holotype; and Black had evidently examined a young stage

af the Hower, On 4 label stuck to the same sheet he describes some details

of a Hower belonging to the same species, this lower being actually a part ot

Isatype—ldem, K.

Charaeteristics—At first glance the specimens cited above and misidentified

at Kew Herbarium with “Pt. cunninghamii Benth.’, do somewhat resemble our

Pi. lanatus A, Cunn. ex Mog. in general facies, But apart from its longer and

more densely standing spikes the newly established species is readily distin-

guishable from Pt, lanatus (var. lanatus and var. glabrobracteatus). Tt has,

wmongst other characters, a seantier pubescence of the rhachis, larger and dif-

ferently pilose bracts, a dissimilar appearance of the bracteoles (s. in Muelleria

1, 2: 107, 1959). The most conspicuous feature, however, is an unmistakably

different indumeutum of tepals: on the outside the lower part, in Pf. lanatus, is

es) G. BENL

covered with relatively thin erispy hairs, the rest with thicker, scarcely noduse

and very dense bristly hairs, like fur. In Pt. lophotrichus there is only a tuft

of relatively few, thin and distinctly articulate hairs. This is a striking pecu-

liarity of outstanding diagnostic importance. The three inner tepals of the Jatter

are Obviously woolly inside, whereas in Pt, lanatus all tepals are glabrous,

Nevertheless, a closer alliance between the two species may be taken for granted,

as they agree largely with regard to the structure (though not the proportions )

of inner floral organs, particularly the eupula.

Because of its characteristic tufts of hairs (hence the specific name!) on the

bracts and bracteoles as well as chiefly on the perianth-segments, Pt, lophetrichus

cannot be confused with any previously described species.

Material—The holotype-sheet consists of four fragments (21 to 24 cm each)

Irom two (?) plants. Taken together they give a very goad idea of the charac

teristic features of the new taxon, especially those of the Hower, since the Inug

spikes are well developed and preserved.

sioribus.

Differt a var, lancifolio Benl indumento multo ampliore, spicis pauci- et

Characteristics—The most striking feature of the present plant is its rela-

tively long and extremely pilose bracts, A grey or dull grey colour, not only of

the bracts but of the entire spike, is a result of the white hair growing on a

brown to dark brown epidermis. This has been unknown in Pt. obovatus so far,

Furthermore, the newly described taxon is conspicuous among the numerous

forms of the exceedingly variable species (s. in Mitt.Bot,St.Sammlg. Minchen

3: 310-512. 1960) for its quite uncommon indumentum in the vegetative purts:

the hairs, especially of the leaves, are not stellate but dendroid, as is usual in

Pl, incanus,

(a) bract; (b) bracteale; (co) outer perianth-segment, inner view; (d) pistil,

In spite of some outward resemblance with Pi. incanus there can, however,

be no doubt that the above form, following the general trend of Pt, obuvatus,

is correctly to be placed within the range of that species. This is indicated

not only by the habit of its inflorescences (long-pedunculated spikes, right-

angled inferior peduncles: s.l.c. 4: 280-281, 1962), but also by the floral details:

besides other characters, the aristae of the bracts and bracteoles as well as

the glabrous tips of perianth-segments are still considerably longer in Pt. incanus,

Among the representatives of var, obowatus bearing brown bracts there

can be found certain plants which may represent intermediates leading to the

present form, such as No. 408/1958 gathered by D. J. E. Whibley on Gawler

Range, S.A. (AD No, 959 31 010; B, K, M, UC). It looks like the typical obovatus

ts regards the kind of its indumentum of leaves and the intensity of pubescence

in the tepals, whereas its large long-acuminate brown, althongh less: pilose,

hract and the entirely glabrous pistil, seem to acvord better with the respective

organs In our well-defined plant, Entirely hairless ovaries may be found, it is

60 G. BENL

true, in var. parviflorus as well as in var. lancifolius. Either of them, however,

has quite a different facies of the spikes; specimens representing transitional

forms were not to be found, though.

In conclusion, the combination of the cited characters makes the new form

distinctive enough to be given a varietal name.

Material—The description is hased on one specimen only, measuring about

45 cm in height and 25 cm in width. But the well-prepared plant has more

than 30 spikes at the tops of its numerous branches and branchlets, thus repre-

senting a very good type-specimen of the new variety.

THE SPECIES OF BASSIA ALL, (CHENOPODIACEAE) IN AUSTRALIA

(Communicated by Hj. Eichler)

[Read 11 June 1964}

SUMMARY

All specinens of Bassia All. (sJat.) im the Australian State Herbaria andl

some private collections have been examined and a key is provided for the 79

species (of which «me is introdnced) and their varieties recognized in Australia,

Oue section, twenty-four species. and three varieties are described as new, neces-

sary nomenclatural changes are introduced, and important details are added to

some species. To many casts only a selection of the specimens examined is

quoted in, order to indicate the known geographical distribution, The index

provides an easy referenve ta the accepted names, synonyms and excluded or

doubtful species.

INTRODUCTION

Since my paper “Bassi uniflora (R.Br.)FvM. (Chenopodiaceae) and its

Allies” [Trans. Roy. Soc. S, Austral,, 48 (1961) 87-98], L have examined Bassia

specimens of all other species in the larger Herbaria in Australia, After having

examined specimens of B, muricata (L.) Aschers., the type species of the genus,

I fee] confident in still considering the Australian species concerned as congeneric,

It may appeal al first sight to segregate the species occurring in the two geo-

graphically isolated regions into Bassin All, comprising the Medilerrancan and

South-West Asian species, and Selerolaena K.Br., with the Australian species.

Sclerolaene R.Br. and Anisecanthu R.Br. are the oldest generic names available;

the type species of Anisacantha (A. divaricata R.Br.) was transferred to Sclero-

laena by Domin (1925), whereas none of the original species of Selzrvlacna

were ever transferred to Anisacantha, Hawever, I could not find any greater

discontinuily in the variation of morphological characteristics between B. muri-

cata (L.) Aschers, and the nearest Australian species than between some of the

Australian species and their closest allies. An wtimate segregation into various

genera may became reasonable when revised on the level of a tribe, but as the

distinction of genera as outlined by Clbrich [in Engler and Prantl, Nat Pflfam.

ed, 2, 16c (1934) 529-540] does not seem acceptable since many mure species

are now known which cannot satisfactorily be placed in either of these genera,

the complex genus Bussia All, is here maintained in the wide sense applied hy

Nove. The type specimen [Dr. H. Beckler, salt plains along the western side of the

Rarrier Range, N.S.Waleés, L861: MEL (/lelotype)| has 3 spines, 2 of them divergent and a

shorter recurved one on the opposite posterior face. Specimens have been collected with

spines up to @ and it is generally agreed to accept this inercase in the number of spines for

the species because of the agreement with the type in other respevts. An example of this is

Perry 5447, near Hale River Crossing, cx. 100 miles E.8.E. of Alice Springs, N.Terr., 8.1X,1955;

ont ol 20 fruiting perianths examined spines were noted as follows: 5 perianths, 4 spines

wl free and separated; 7 perianths, 4 spines ull free and separated; 7 perianths, 5 spines, 2

of which are collateral: ] perianth, 6 spines, 2 of which are collateral; one of the 2 collaterit!

spines ig usnally shart to very short, uot half as long as the other, none seen were equal in

length. ‘The similar, B. densiflora Vitvg. has consistently 5 spines, 2 of them collateral and

all equal in length, and T retyin it.as a valid species hevause T have seen no specimens of the

“lanicuspis” sroup haying the 2 collateral spines of ecuial Tength, B. dentiflara is endemic

in W. Austral, and does not appear to vary in the spine character. B. Janicuspis also occurs 1n

Norr, This species shows some variation in the collections, chiefly in the perianth and

spines. The holotype hag av oblong perianth and 4 spines, the shortest spints straight jul

often diverging upwards. Some specimens examined have a turbinate or obeonie perigath

abeait as Jong as wide; spines may be 3 enly ov 3 with a 4th rudimentiry or very short.

Sometimes the short spine iy horizontally curved across the posteriar face af the penanth.

The limh, however, appears ta be constantly bent inwurds (inunrved ) and definitely not erect.

Nore. The original description, in part, of B, spinosa Ewart and Day, is “fmitting

perianths connate into a hard inass of ahout 2’ diam.” T have examined isotype material

(AD) and cut sections of the “hard mass” and found in it several perianths and irregular

tunaelling in which was an empty case or shell of the vacated insect. This is proof zhat

the “hard mass” is a monstrous formation, an insect gall, Chippendale |Trans.Roy Soc,S.Austral,

INSUYFICIENTLY KNOWN “TAXA

80. Bassia sp. aff. B. brachyptera (FyM.)Anders—E, M. Packe; NSW

35253; Sandalong Golf Links, ca. 14 miles east of Mildura, Victoria, 29.1X.1949.—

The only specimen I have so far scen is a branch ca. 9 om long with several

short branchlets and a few flawers and perianths. ‘This specimen has. branches

and leaves sparsely pubescent; Ieaves 5-8 min long; spines straight, one more

obtuse arid longer than the others; base shallow, areole thin. Although the dif-

ferences between this specimen and B, brachyptera are fairly well marked it

sverns better to wait for more material before describing it as a new species,

$l. Bassia sp. afl. B. elubra (FvM.)FvM.—F. Mueller collected material at

Sturts Creck, N. Terr, (near W. Austral, border) in 1856. Part of the material

was named Bassia glabra and part Kentropsis glabrap longicuspis by Mueller,

but the latter was not pwhlished, However, t.66 figs. | and 6, le. Austral,Salsul.PI.

7(1891), illustrates this “variety, but.as no other material is available it is advis-

able to delay publication as a new species for the time heing.

$2. Anisacantha kentropsidea FvM., Trans.Vict.Inst. 1(1855)133.—This

name was tentatively placed as a synonym of B. diacantha (Nees)FvM, in Isiny,

Trans.Roy.Soc.$.Austral. §4(1961)91. As no type specimen could he located, the

application of this name remains doubtful.

$3. Bassia intrecala var. hirsula Black. FLS.Austral, (1924)194. “Branches

and Ieaves tomentose. Everard Range.” [ have searched for this specimen, but

have riot found it in any Australian Herbarium, It is not recorded in the second

edition of Black’s Flora,

which is probably ut Kew (K) and, therefore, am nnable to make any comment.

83. Kentropsis lanata Mog., Chenop.Enum, (1840)83; Moq. in DC., Prod.

FvM, [Sclerolaena bicornis Lind].] in Bentham, Fl.Austral. 5(1870)195. I have

not yet seen the type specimen [“In Nova-Ilollandia (Cunningh.). Salsola ?

mollis Cunningh, in herb, ... (v.s. in h.Mus.Paris.ct Hook,)"] and consider its

position, therefore, as doubtful.

86, Sclervolaena coriaeea Mog. in DC., Prod. 13/2(1849)123.—The only

specimen cited by Moquin is “In Novae Hollandiae ins,sterilibus (h.Mus,Paris! ).”

In his description he says .. . “calvce fructifero mutica...” Having no spines,

this specimen apparently is not a Bdssia, but as yet I have not scen the specimen,

Bentham, Fl.Austral. 5(1870)194, referring fo this specimen says that it was

unknown to him and doubted if it was a true congener as it had no spines, Ander-

son, Proc.Linn,Soe.U.S,Wales 48(1923)354, also mentions Bentham’s reference,

TWO NEW SPECIES OF AUSTRALIAN FROGS OF THE HYLID

GENUS NYCTIMYSTES

BY MICHAEL J. TYLER

Summary

The Hylid frog genus Nyctimystes is reported from Australia for the first time. Two new species are

described from montane rainforest in north-eastern Queensland, and it is suggested that the

distribution of Australian Nyctimystes will prove to be confined to similar environments within that

area.

SUMMARY

The Hylid frog genus Nyctimystes is reported from Australie for the first

time, Two new species are described from anontane rainforest in north-eastern

Queensland, and it is suggested thut the distribution of Australian Nyctimystes

will prove to be confined to similar environments within that are;-

INTRODUCTION

Within the Australian zoogeographical region the frog family Hylidae is

represented by two genera: Hyla and Nyctimystes. Nyctimystes (as re-defined

by Zweifel, 1958) may be distinguished from Hyla by the presence of a pal-

pebral venation and the shape of the constricted pupil (a@ vertical slit in Nyeti-

mystes as opposed to a horizontal slit in Hyla), Myla is widespread throughout

Australia and New Guinea, whercas Nyctimystes is believed to be confined to

New Guinea,

In 1956, Mr. William [losmer collected a small, conspicuously coloured

Hylid frog in north-eastern Queensland which subsequently proyed to be a

Nyctimystes species,

A seeond specimen of Nyctimystes from north-castern Queensland was

recently found by the author amongst a collection of unidentifed Australian

Hylids received on loan trom the Naturhistorisches Museum of Vienna. Com-

parison of this specimen with the one taken hy Hosmer reveals that they are

distinct species, each of which is new to. science.

Nyetimystes hosmert new species

Holotype—American Museum of Natural History No. 65538, a male from

Tully Falls, Cape York Peninsula, Queensland, Australia, collected by Mr.

Williain Hosmer on April 22, 1956,

Description of Holotype—The vomerine teeth are in two small, almost

cirenlar series which ure widely separated from oue another and situated he-

neath the posterior borders of the choanac. The tongue is halt as wide as the

mouth, cordiform in shape, its posterior border free and yery slightly indented.

The head is slightly longer than broad (head length 11-$ mm; head breadth

11:4 mm). The snout is rounded when viewed from above, and rounded in

profile with an obscure canthus rostralis and oblique loreal region, ‘UVhe nostrils

are inconspicuous and separated from one another by a distance which is slightly

less than the distance between naris and eye: cye to naris 3-4 mm: internarial

span 3°2.min. The eye is prominent with a horizontal diameter of 4-7 mm;

the pupil is almost completely dilated and nicked medially on its superior and

interior horders, The tympantum is small, 1-4 mm diameter, and indistinct and

separated from the eye by u distance equal to its own diameter.

The distance between the snout and the vent is 33-5 mm,

The ngers are long and slender with small terminal discs, and are approxi-

inately one-half webbed. The fourth finger is slightly longer than the second,

but does not quite reach the disc of the third; the dise on the third finger covers

approximately two-thirds of the tympanum. There is a rudiment of a pollex

which projects slightly

The toes are almost fully webbed, the webbing on the fourth tue reaching

the base of the penultimate phalanx and continuing to the disc as a fringe. The

toe dises are smaller than the finger discs; the disc on the fourth tue covers

slightly more than one-half of the tympanum. There is a narrow inner but no

outer metatarsal tubercle. The legs arc rather long; the tibia length is 18-8

mm and the ratio of tibia length to snout to vent length is 0-561, When the

hindleg is adpressed the heel reaches well beyond the tip of the snout; when the

limbs are laid along the sides the knee and elbow overlap considerably; when

the hindlegs are bent at right angles to the axis of the body the heels overlap

slightly,

: The skin covering the dorsal surfaces of the head and body is smooth except

in those smal] areas marked with cream where it is granular. The lateral surfaces

are slightly granular, and the throat, chest, abdomen and lower femur coarsely

granular. There is a weakly defined supratympanic fold, but no trace of a

skinfold across the chest,

The dorsa] surfaces of the head, body and limbs are dark brown, On the

head and hody are several ronghly circular, asymmetrically arranged, large cream

spots, Hach of these spots lus a black ventre. On the tibiae are traces ot

irregular banding or marbling of pale brown. The lower surfaces of the limbs

are at dull yellowish-brown; the posterior surfaces of the thighs are dark brown

and there are traces of pearl in the groin.

The palpebral venation consists of pearl-coloured veins distributed in the

form of a reticulum, with a tendency for most of the longer veins ta be orlentated

in the vertical plane,

Collector's Notes—The specimen was found on a leaf of a tree during the

daytime. Its colour in life was described as light green above with conspicunuc

white, black-centred, spots; below yellowish-white; anal region darker, Taker

at an altitude of 2,670 [eet ahove sea-level,

Comparison with other Spectes—The unusual colouration and the long

slender digits with their very small dises will distinguish N. hosmeri from the

sixteen other species known at the present time. Two species (N. humeralis

(Boulenger) and N. forleula Tyler) share with hosmeri a similar dorsal colour,

Init these species lack the distinctive markings exhibited by hosmeri. Nyctimystes

Remeralis is an extemely large species in which the males may attain a length

of up to 100 mm, and are characterised by the presence of a’ sharp projecting

spike on the interior face of the humerus, The palpebral venaliun of foricula

consists of extremely broad, oblique, black veins permitting light ta enter via

narrow slits, In hosmeri the veins ave extremely broad and torm aa irregular,

Holotype—Naturhistorisches Museum, Vienna, No, 17187, 4 female from

Mount Bartle Frere, Cape York Peninsulie, Queensland, Australia, collected Feb-

ruary, 1897, Collector nnknown.

Description. of Holetype—The yorncrine tecth are on two large, triangulur

elevations fused in the midline and lying beneath the small, oval choanae. The

tongue is one-third as wide as the mouth and cordiform in shape, its posterior

border free and very slightly indented, ‘the head is large, flattened and

broader than Jong (head breadth 18-3 mm; head length 17:9 mm), The snout

is large, rminded when viewed from above, and strongly raunded in profile,

The canthus rostralis is straight and inconspicuous; the loreal region is concave

and oblique, the upper lip flaring out strongly below it. The nostrils arc

promiment and separated from one another by a distance which is slightly less

than the distance between eye and navis; eye tu naris distance 5-0 mm: inter-

natial span 4-6 mm, Tho eye is large and prominent, its horizontal diumeter

5-8 mm; the pupil is dilated and nicked snedially on its superior und inferior

borders. The tyinpanum is small with a diameter of 1-8 mm, and indistinct,

only 4 portion of the tympanic annulus bemg visible; the lympanum is separated

from the eye by a distance whieh is nearly equal to the diameter of the

tympanum.

The distance between the snout and the vent is 53-2 am.

The fingers are broadly fringed and two-thirds webbed, the webbing on

the outer finger reaching slightly above the subarticular tubercle at the base:

of the penultimate phalanx; fourth finger longer than second, nearly reaching

disc of third, which covers about two-thirds of the tympanic urea. ‘The first

finger is almost completely opposed to the fourth. The finger discs do not

project laterally beyond the fringes,

The toes are fully webbed and the dise of the fourth toe covers slightly

more than two-thirds of the tympanic urea, There is a distinct, narrow, oval

immer but no outer metatarsal tubercle, The legs are rather long with a tibia

IL4 M. J. TYLER

length of 28-7 mim, and a tibia length to snout to vent length ratio of 0539.

When the hindleg is adpressed the heel reaches beyond the tip of the snout,

when the limbs are laid along the sides the knee and elbow overlap slightly,

wiiga, the hindlegs are bent at right angles to one another the heels overlap

slightly. :

The skin covering the dorsal surfaces of the head and body is minutely

clandular. The lateral surfaces of the body are slightly granular, and the thruat.

chest, abdomen and lower feraur coarsely granular. There is a wide patagium

extending from the back of the upper arm to the side of the body, a supri-

tympanic fold hiding the upper portion of the tympanum and w disrupted dermal

ridge along the outer edge of the forearm.

The dorsal surfaces of the head, bedy and limbs are light brown with

indistinet creamish-brown markings as follows: a poorly defined patch beneath

the canthns rustealis, and irregular mottling on the coccygeal region, thigh,

tibia, foot, forearm and hand. The posterior surfaces of the thighs. are very

dark brown. The lower surfaces of the body and limbs are cream; the palmar

and plantar surfaces are pale brown, and the anterior surface of the thigh a pale

slate colour.

The palpebral venation consists of a few fine, slightly disrupted, Jaryely

vertical veins.

Comparison with Other Species—The presence of extensively webbed fingers,

apposable first finger and the form of the palpebral venation distinguish N, vestiges

from N. hosmeri and all other Nyctimystes species known at the present Lime.

The finger webbing of N. perimetri Zweifel is almost as extensive as that of

vestigea but, in addition to the differences in the position of the first finger and

the form of the palpebral venation (a pattern of oblique to almast vertical lines

with a few horizontal connections in perimetri), pertmetri exhibits a triangular

dermal appendage on the heel and a distinct tympanum, and there is little

likelihood of confusing the twa specits.

DISCUSSION

‘The eighteen Papuan Nyctimnystes species known at the present ime are

confined to areas of subtropical rainforest, There are only two records of speci-

mens being found at altitudes of less than 1,000 feet above sea-level, and in

fact the vast majority have nat been taken helow 3,500 feet. As the N. hosmeri

holotype was collected at an altitude Gf over 2,500 feet at Tully Falls and it is

possible that the vestigea holotype could have been taken at a similar elevatiun

un Mt. Bartle Frere. it seems reasonable to predict that the distribution of

Nyctimystes in Australia will prove to be restricted to montane rainforest. Such

a Uistribution pattern would provide a parallel to that of the Australian specics

ct the predominantly Papuan Microhylid genera Cophixalus and Sphenophryne

reported by Zweifel (1962).

It is a mallee in habit, 3-4(7m) high with rough bark at the base, smooth

and grey in colour above. Cotyledons deeply bifid, seedling leaves at three

months of age number § pairs, the first pair being sessile, the others shortly

but distinctly pediccllate, narrow-lanceolate 3 em x -8 cm. Mature foliage pale

yellowish green when dried, to sub-glossy dark green when fresh; thick enough

to be rigid when dried, well spaced along branchlets, alternate, tapering at the

apex to a long acuminate point and at the base gradually into the petiole which

is sometimes twisted.

Venation obscure in dried material; central vein furrowed on upper surface,

of characters include a long peduncle of § mm (18 miles north of Curtin Springs,

This species is typically found on reddish sand dunes associated with well-

recognised drought resistant species, such as Triodia basedowii, T. pungens, and

Cassia nemophila. In the easier conditions of the ranges it is found associated

with Eucalypts, E. oleosa, E, gamophylla or E. oxymitra; and occasionally L.

terminalis (J. Johnson, personal communication).

Its position would seem to be in the series Subulatae (Blakely) because of

its longish, fragile subulate valves; but the broad, flat to raised disc to the capsule

separates it from the broad conical operculum forms of E. oleosa which appears

to be nearest to EB. mannensis.

PERMIAN-JURASSIC HISTORY OF THE WESTERN GREAT

ARTESIAN BASIN

By H, Worrnen®

[Read 13 August 1964]

SUMMARY

The Late Palaeozoic and Ue Mesozoic history of the western portion of the

Great Artesian Basin was characterisecl by periods of short-lived intereratonic

sedimentation which were scparated hy extensive intervals uf erosion, ‘he

periods of sedimentation were the Lower Permian and the Upper Jurassic-Lower

Cretaceous.

The Lower Petmian sequence, comprising in ascending order, glacigene,

marine and freshwater deposits, obtained their preatest thickness in deep, narth-

west to north-noerth-west trending troughs Sf derieehthy pre-Permian origin.

The upper Jurassic deposits consist substantially of terrestrial beds but become

freshwater in otigin towards the deener (eastern) portion of the basin, The

presence of Middle Jurassic freshwater strata is predicted beneath the urea of

Lake Eyre, ‘he western boundary of Middle Jurassic deposition is formed

by a north-north-west to north-west trending hinge zone, situated along the

western shore of Lake Eyre and termed the Lake Eyre lineament,

The interval between the Permian and the Middle to Upper Jurassic was

a petiod of erosion which, in conjunction with (?) pre-Middle Jurassic uplifts

in the area west of Lake Eyre, led to severe truncation of the Lower Permian

sediments and older rocks. As tnincation approached near-peneplain conditions,

Jateral tetpert gradually decreased and a strongly kaolinised, deep weathering

proms developed. Lateral transport was apparently eastward and led to the

eposition of the kaolinitic-Middle Jurassic sundstunes (Walloon and older equi-

valents) in the depressed arcas east of the Lake Fyre lineament.

The process ef peneplanation was terminated by the Lower Creticeous

Lianstression,

INTRODUCTION

Recent investigations of the Western Great Artesian Basin by the South

Australian Geological Survey have revealed some interesting aspects of the

pre-Cretaceous history of this portion of the basin. In addition, data became

available from recent exploration by the French Petroleum Company of Ans-

traliz and some of this information has been incorporated.

The purpose of this paper is to summarize available information and to

lry to answer a few of the many questions regarding the geological cyents con-

trolling the present distribution of the Lower Permian and Jurassic sediments,

THE AREA

The area dealt with in this paper comprises the western portion of the Great

Artesian Basin, approximately between 134° and 138° east longitude.

Monotonous plains and low table lands form the characteristic features of

most of the area, The monotony of the topography is only interrupted by the

Peake and Denison Ranges and the Stuart Range,

The Peake and Denison Ranges consist of a NNW trending chain of rngged

Upper Proterozoic hills which rise to a maximum elevation of 1,350 feet above

permission of the Director of Mines,

sea-level, As a morphological feature, these ranges are not older than Upper

Tertiary, as indicated by steeply dipping Mid-Tertiary duricrust, dragged along.

the taults which led to the present elevation of the raliges.

The Stuart Range consists of low, slightly west dipping cuestas formed by

Cretaceous and Tertiury strata,

Purely on the development of the Mesozoie sequence, the westerm Creat

Artesian Basin can be subdivided into a stable, western “shelf"-area and a newa-

tive, eastern basin-area. The stable area is characterised by thin Mesnavic

deposition whilst several thousand feet of Mesozoic sediments were laid down

in the negative basin area, The boundary between these two areas is formed

by a NW to NNW trending zone of faultmmg and monoclining situated approxi-

mutely along tie western shure of Lake Eyre. For convenience this zone js

referred to as the Lake Eyre Lineament. Faulting affecting Cretaceous strata

tan be observed on outerops at the lower reaches of the Neales River, abant

two to six miles east of the Lake Eyre shore. The latest movements are neat

older thai Upper Tertiary, similar to the movernents which tock place on the

easter margin of the Peake and Denison Ranges. However, syn-Mesozuic

movements must have taken place so as to aflect the deepening of the eastern

huisin avea., This is inclicated by some seismic evidence, as shown in Fig. 3.

The importance wf the Lake Eyre Lineament as a line of demarcation for

perMesuzoiv racks is problemutical,

STRATIGRAPHY

Pre-Perxuan

The oldest known rocks in the area are granites. hornblende-graniles,

adamellites and gneisses. They ave purt of the Australian shield and are Archean

wt Lower Proterozoic in age, They are widely exposed along the south-west

margin of the Great Artesian Basin and form the basement inlier of Mt. Wooils

Luke Eyre, where (hey occasionally protrude through the younger sediments ic

forin small, isolated inliers like Lagoon Hill, Mt. Charles, and Springhill.

The nature of the pre-Permian rocks beneath Lake Eyre is unknown but it

is generally thought that Upper Proteruzoie ta Lower Pulaenzoic sediments

underly this portion of the hasin.

PERMIAN

Permian sedimentation was initiated by ubiquitous deposition of glacigene

material, ranging from basal tills to fluvio-glacial and glacio-marine sediments

higher up the sequence, These glacial sediments are of Lowermost Permian to

perhaps Uppermost Carboniferous age and they rest unconformably on any af

the older racks described previously, The yvlacigene deposits eousist of pebble

to boulder beds with generally textureless cluyey or sandy matrix (Plate 1,

Vig. 1). Outerops of these beds along the Peake and Denison Ranges exhibit

a great abundance of soled, striated and saimetimes Huted pebbles (see Plate 1.

Fig, 2), They are dominantly locally derived from the underlying Upper

Proterozoic sediments and commonly facetted and striated cobbles or boulders

consisting of well-consolidated Sturtiin Tillite (Adelaide System) can be oh-

served, Some outcrops show indistinct, sometimes distorted bedding of the

sandy matrix, indicating deposition under fluvio-glacial environment.

The Lower Permian glacial sediments are widely distributed slong the

western Hank of the Peake and Denison Ranges. The same beds were also en-

countered at the base of the Permian sequence in the Lake Phillipson, Coorsie

Appa, Margaret Creek and Anna Creck bores (Ludhrook, 1981). They are further

known from Yellow Cliff near Finke, from where, in fact, the first Ceutral

Australian occurrence of Permian glacials was described (Tate, 1898). Tillites

of assumed Permian age and containing plentiful striated, soled and fluted

pebbles and boulders also occur in the Ficld River area (N.T.) on the northern

margin of the Great Artesian Basin. They rest unconformably on Upper Pro-

terozaie sediments and should nat he confused with the Upper Proterozoic “Field

River Glaecials” or overlying clastics of Mesozuic age.

There can be little doubt as to the true glacial nature of these basal Permian

beds, They show all the criteria one can expect to observe on a tillite except

glacial pavements. Furthermore, their age is identical with occurrences in

southern South Australia where ut several lovalities Lower Permian boulder

tills fest on well-preseryed glacial pavements (e.@. Inman Valley) (Campana

sud Wilson, 1955; Horwitz, 1960).

The basal glacigene horizon is followed by a few hundred feet of Tver

Sakmarian marine calearenites and shale. This horizan has not been recognised

in wutcrap, but was proyed in several bores, eg. Lake Phillipson, Boorthanna

arkL Coorie Appa (Ludbrook, 1961).

The marme horizon is overlain by a thick fresh-water sequence of Upper

Sakmarian to Lower Artinskian age (Balme, 1957; Ludbraok, 1981), Tt consists

af bituminous shale, carbonaceous siltstone and sandstone and is concluded by

widespread depasition of coal. This unit is known from many bores alony the

westernmost Arlesian Basin and its existence has been proyed as far north as

Malcolm's Bore, ahout 100 miles NE of Finke (Balme, 1959). The only knows

outerop is at Mt. Toondina where | B. Frevtag (1963) discovered glossopteris

and other Permian plant remuins in a distorted and steeply dipping siltstone,

shale and coul-sequence (Plate 1, Fig. 3).

The freshwater sequence appears to overlap the marine horizon (Rochuw,

1963). Considerable thinning of the freshwater sequence takes place actoss

stru¢tural highs, which demonstrates the existence of a pre- and/or syn-Permian

topography.

No Upper Permian strata have been recorded from the area and it is

assed that the deposition of the Artinskian freshwater and coal beds con-

chided the Permian sedimentation,

Present duy distribution of the Lower Permian is the result of the interplay

of several factors, viz. pre- and syn-Permian topagraphy and structure, pust-

Permian uplift and tilting of the southern portion of the area and pre-Upper

Jurussic truncation,

Two areas of major Permian distribution occur on the western side of the

Peake and Denison Ranges: the Boorthanna trough situated between the Pro-

terazoie ranges and the Archean of Mt. Woods, and the Lake Phillipson trough,

WSW of Mt. Woods (Fig. 1),

The Boorthanna trough is fault bounded on its eastern side but onlaps onto

the Archean of Mt. Woods on its western limit and onta Praterozvic ta the

south. Its axis tends NNW and shows a marked plunge to the north (Fig, 2},

vaused by post-Permian uplift of its southern portion, Aeromagnetics and recent

seismic reflection suryeys carried oul by the S.A, Department of Mines show a

miximim depth to the pre-Permian unconformity of about 4,500 feet in the

vicinity of Mt. Tvondina (pers. com, B, A, Milton and K, R. Seedsman).

Little is known about the Lake Phillipson trough and its configuration is

still somewhat problematic, The Lower Permian encountered in the Stuart

Range bores Nos, 1 and 2 probably belong te the same trough. A shallow inter-

veusection between the Lake Phillipson trough and the Boorthama trough in

the yieinity of Mt. Willoughby is indicated by sparce seismic evidence (see

Fig. 1).

No Permian sediments are known from the area between the Peake and

Denison Ranges and Lake Eyre. Except for a few shallow water bores which

penetrate only the Mesozoic sequence to the lop of the Algebuckina Sandstone,

there is litthe subsurface information available from this area,

A seismic reHection survey, comprising two-mile correlation shooling and

intermittent continnons profiling was carried out by the S.A. Department of

Mines behveen Mt. Dutton and the northern shore of Lake Eyre (see Fig. 3).

Between Mt, Dutton and shot point D.K. 28, the survey shows # thin Mesozoic

sequence (Algebuckina Sandstone and younger) resting directly on a shallow

high velocity lever. representing Proterozoic or Archean basement.

East of shot point D.K. 28, however. consideruble and rapid deepening of

the “hasement” reflector is observed, As shown in Fig. 3, the deepening of the

basement is effected by a series uf faults and flexures affecting both Mesuzeic

and pre-Mesozoie rocks. These faults are part of Ihe Lake Eyre Lineament ancl

a NW to NNW trend af these faults is indicated. In conjunction with the deep-

ening of the basement. however. additional séismic reHectors appear below the

horizon of the Algebuckina Sandstone (“C") and the “Basement” (“Z"). These

intermediate rcHectors, designated P; and P., are considered to represent Lower

Permian sediments.

In Fig. 1, the western limit of Permian reflectors is connected to the area

af Permian outcrop near Finke and this fine is considered the western limit of

Lower Permian suberop within the Lake Eyre Basin. This line has recently

heen substuntiated by two more seismic [raverses and by the French Petroleum

PERMIAN-JURASSIC HISTOHY OF WESTERN G.A.B. 123

Company's vil exploration wells, Witcherrie No. 1 and Purni No. b. which both

encountered Lower Permian sediments underneath the Mesozsic sequence.

The eastern and southern bourdaries vf Lower Permian distribution, as

shown on Figs. ] and 4, may be regarded as conjectural. However, seistuic

data obtained by the S.A. Department of Mines along the Birdsville track show

that Permian sediments are absent over this upwarped region, Furthermore, it

will be noted on Fig, 4 that no Permian was encountered in the Delli-Santes

Well Pandieburra No. 1,

Correlation between the Lower Permian of the western Great Artesian Basin

and the Permian encountered hy recent petroleum exploration work in the Innu-

ininicka-Gidgealpa area is still uncertain and beyond the scope of this paper, The

discussion of this problem cannot be attempted until reliable datings of this

eastern Permian sequence are available. From the sparse information ou lane

it appears that this sequence may extend well into the Upper Permian,

Jurassic-Cretackous

Within the western Great Artesian Basin, the oldest Mesozoic sediments

can he expected in the deeper parts of the basin, Le. east of the Lake Eyre

Lincament, The reader will recall the pronounced deepening of the basement

east of shot point D.K. 28, along the Mt. Dutton-Like Eyre seismic line. Together

with this deepening of the basement and the appearance of Permian reflectors,

one also observes a marked Increase of the interval “P"“C” (Fig. 3). This

thickening of the post-I'ermian section beyond the normally experienced thickness

of the Upper Jurassic seqnence is thought to be duc to the presence of Middle

Jurassic sediments (Walloon equivalents and older), similar to the known Middle

Jurassic succession as revealed by recent drilling us far west as 130°25’ vast

longitude (Delhi-Santos Pandieburra No, 1). Sediments of Middle Jurassic

age were also encountered in F.P.C.A, Purni No, | well. Unfortunately, how-

ever, it is not known whether the Middle Jurassic sediments overlap or outlay

the Lower Permian.

West of the Lake Eyre Linegment, Middle Jurassic sediments ace absent

and the oldest Mesozoic rock known from outerop as well as from subsurface

information is the Algebuckina Sandstone. It forms the basal stratigraphic unit

of the Mesozoic sequence in the westernmost portion of fhe Creat Artesian

Rasin.

The Algebucking Suidstane rests unconformably on either Permian, Pro-

lerozoic or Archean rocks (Figs. 2.and 4), which ure invariably and intensely

kaolinised beneath the contact (Plate 2, Figs. 1 and 2). This feature is particu-

larly evident on feldspar-rich metamorphics such as gneiss or schist in whicli

quarts romained the only unaltered constituent,

The busal beds of the Alecbuckina Sandstone consist of white, cogrse and

eross-bedded, kaolinitie sandstones and lenticular pebble conglomerates. The

dominant constituents. of the conglomerates are pebbles of milky quartz of au

average size of two to five inches diameter. Pebbles of quartzite, tourmnuline

quartzite and acid igneous rocks occur as accessories. The pebbles are generally:

well rounded but dreikanters and case hardened, hollowed and pitted pebbles

are commen. The hysal conglomerates also contain residual gold deposits

(Brown, 1894), These characteristics in conjunction with the strong kanlinisa-

tion of the underlying racks indicate that the basal Algebucking Sandstone was

furmed on a deep weathering profile under terrestrial and Huviatile conditions.

he basal terrestrial-fluviatile depusits are followed by clean, coarse to medium-

grained [acustrine sandstones, containing well-preserved plant fossils of Lymer

Jurassic to Lower Cretaccous age (Wopfner and Heath, 1963),

The Algebuckina Sandstone is considered to be an equivalent of the Upper

Jurassic formations of the Blythesdale Group.

The maximum thickness of the Algebuckina Sandstone measured on out-

eraps along the Peake and Denison Ranges is about 120 feet, Tlowever, the

thickness increases to. the north (186 teet in Suntus Oounadatta No, 1 well)

and to the east, particularly across the Lake Eyre Lineament.

The Algebuckina Sandstone tarms a nearly continuous blanket, shrouding

most alder rocks of the westera Great Artesian Basin, Its cover is interrupted

only where basement inliers break the surface (Fig, 4).

In the northern and eastern portion of the western Great Artesian Basin, a

transition zone leads from the non-marine Algebuckina Sandstone to the Lower

Cretaceous marine shale sequence. In the southern parts, however, a coarse,

transgressional facies is developed which commonly overlaps the non-narine

sequence, (Due to the small vertical seale, this sandstone is not separately

shown on cross-sections Figs. 2 and 4.)

GEOLOGICAL HISTORY

From the evidence presented in the previous part of this paper, the follow-

ing sequence of geological events can be deduced:

1, Deterioration of climatic conditions and lowering of the mean temperature

in the Uppermost Carboniferous Ied to extensive glaciation, covering « stable

and mature land surface of pre-Permian origin. ‘lo what extent and in what

manner this surface was controlled by geolovical structure is uw question which

still needs clarifying. '

2. The scouring action of the glaciers superimposed a distinctive glacial

topography onto this. pre-Permian landscape which led to the development of

well-defined Permian troughs. At the same time, widespread deposition of

moraines and other forms of glacial debris took place.

3. On the retreat of the ice-cover the sea advanced and the Lower Sakmarian

horizon was deposited. Glacial compovents were incorporated by means of

reworking and ice drift, whilst Huvio-glacial sediments were laid dawn in the

wake of the retreating glaciers,

4. Marginal uplift, perhaps induced by crustal rebound following the re-

moval of large parts of the ice cover, disrupted the connection with the open

sea in Upper Sukmarian time, A continuing and excess influx of freshwater

flushed out the remaining basin and subsequent sedimentation veeurred in a

substable, intracratonic freshwater basin or basins. As the troughs filled up

with sediments they became decidedly shallow and swampy, so forming the

enviroument in which the Lower Artinskian carbonaceous sequence was

deposited.

5. The succession of events in the Lower Permian, viz. glaciation — marine

incursion — freshwater deposition and swamp environment. is surprisingly similar

tu the sequence of Quaternary events in northern Europe. One might speculate

therefore whether the Lower Permian succession was not similarly cuntrolled

by isostatic adjustments and fluctuations of sea-level,

§. The interval between the Artinskian and the Upper Jurassic, eovering

some 80 to 90 million vears, was essentially a period of erosion, demidatian anc

peneplanation. As the surface reached the stuge of a near peneplain, deep

weathering profiles devcloped,

7, These processes were only briefly disturbed by minor uplifts and faulting

Which affected the area between the western margins of the Peake and Denison

Runges and the Lake Eyre Lineament. Positive movements also look place in ihe

Margaret Creek area and, following Upper Triassic sedimentation, also in. the

northern Flinders Ranges. These positive movements were responsible for the

narth-tilling of the Tower Permian troughs (Fig. 2), ‘The dating of these move-

ments is obscure. Evidence from the Leigh Creek region in the northern

Flinders Ranges suggests a post-Triassic age (Parkin, 1953), Furthermore, it

iy thought that the positive movements west of the Lake Eyre Linearnent were

compensated by down warping east thereof, thus conceding the deposition of

Middle Jurassic sediments, Todeed, the uplifted western regions wonld have

furnished the sdurce for the highly kaolinitie clastic material of the Middle

Jurassic deposits, [Tf this reasoning is correct, the movements have to be placed

in the upper Lower Jurassic. If would futher mean that the Lake Eyre Linea-

ment approximates the Middle Jurassic shore line,

8. West of the Lake Eyre Lineument, however, terrestrial conditions pre-

vailed and the country mderwent extensive peneplanation, whilst the uplifted

portions were eroded and truncated and substantial portions of the Permian

sections were stripped, particularly io the southern parts of the area (see Fig. 2).

Soon, however, the uplifted portions were reduced to a near peneplain again.

Rudiments of palaeosoily and ferruginisation of the Permian sediments at the

contact with the Algebuckina Sandstone (Heath, 1963) as well as the intensive

kaolinisation of ulder rocks at the same contact bear witness to prolonged ex-

posure to weathering.

9. The overlying basal units of the Algebuckina Sandstone also indicate

the existence of a Jurassic peneplain, The combination of the basal conglomerate

itself, consisting of the most resistant materials only, the presence of dreikanters,

the abundance of case-hardened, hollowed and pitted pebbles and the enrich-

ment of alluvial gold are together characteristics of a terrestrial residual depasit

developed by prolonged weathering under peneplain conditions. The compata-

tively small amonmnt of debris which was laterally removed was transported eust

and deposited in the shallow Middle Jurassic freshwater hasin which existed

east of the Lake Eyre Linewment.

10. Slight subsidence in the Uppermost Jurassic Jed to partial inundation

of this peneplain and the deposition of the plant bearing freshwater sandstone.

I. The Lower Cretaceous marine transgression finally covered the whole

of this ancient peneplain, Pronounced subsidence to the east of the Lake Eyre

Lineament resulted in the development of a thick Cretaceaus marine sequence.

The area west of the lincament, however, remained shallow and comparatively

stable througheut the existence of the Cretaceous sea.

LOWER CAMBRIALN STRATIGRAPHY OF THE FLINDERS RANGES'

BY C. R. DALGARNO

Summary

The distribution and relationships of Lower Cambrian units in the Flinders Ranges are illustrated by

a panel diagram and sketch maps.

A new rock name, Hawker Group, is introduced for six formations of Lower Cambrian age which

represent a phase of marine transgression following the deposition of the Pound Quartzite. An

archaeocyathid biostrome development associated with graben faulting above the Oraparinna Diapir

is noted.

The Billy Creek Formation is considered to lie disconformably on the Hawker Group in several

areas and to represent a widespread phase of uppermost Lower Cambrian marine regression. A thin

but persistent tuffaceous unit occurs in the lower half of this formation.

INTRODUCTION

The early reeards of Cambrian sequences in the Flinders Ranges are those

of Howchin (1922, 1925). in which he described the Bunkers Range and Wilson

sections, and Mawson (1937, 1938, 1939), who recarded two sections at Nepa-

bunna and the Parachilna, Ten Mile Creek and Balcoracana sections, Segnit

(1939) gave a description of the Mt. Svott Runge and exposures near Anda-

mooka to the west of Lake Torrens,

The only detailed biostratigraphic study has heen carried out by Daily

(1956), From the Flinders Ranges he discussed the Wilson-Quorn, Mt. Scott

and Yen Mile Creek sections. His paper vives a comprehensive historical

Regional mapping of Cambrian exposures of the northern Flinders Ranges

was largely completed by the Geological Survey by 1953. Subsequently, [orwitz

(1962b) mapped the sheet Arrowie and completed Cadnia using the work of

R. Grasso (unpub. M.Sc. Thesis, Uniy. of Adelaide). Webb and Von der Borch

(1962) have mapped the Cambrian synclines of the Wilson and Quorn areas

in the southern Flinders Ranges.

Sections measured during 1956 hy R. B. Wilson (unpub.) for Santos Petro-

leum were the first Cambrian traverses at Brachina and Bonyeroo on the western

Hank of the central Flinders Ranges. B. Daily (pers. comm.) identified from

fussils collected, the three important limestone units of the Lower and Middle

Cambrian. In 1959, Daily (unpub.) recognised the Wirrealpa Limestone in the

Mermmmema syneline and he subsequently tabulated the rock units and the

fannal assemblages present in that locality.

B. P. Webb (unpub.) compiled a sketch section of the Lower Cambrian

sequence east of Reaphook Hill alter a brief reconnaissance traverse in 196]

of the hitherto unknown Cambrian exposure.

STRATIGRAPHY OF THE FLINDERS RANGES 131

The Wirrealpa Limestone was recognised west of Wertaloona H.S. by R. P.

Coats; and brachiopods and trilobite fragments collected by J. E. Johnson and

the author from this limestone during 1960, were identified by B, Daily as

referable to his faunal assemblage ten. The sequence extending to the south

was faund to be a fairly complete development of the Lake Frome Group. East

of Mt. Frome, a further area of exposure of the Lower Cambrian sequence and

Wirrealpa Limestone has been mapped (Dalgarno and Johnson, 1963).

The present paper gives the general relations, distribution and approximate

thicknesses of the formations employed diving mapping of the central Flinders

Ranges together with details of the mapping im some of the areas which have

proved critical to the understunding of the relationships of the units. The

oceupy broad synclines with moderate dips. Faulting is relatively common and

oblique structures with displacements of a few hundred feet often show influ-

ence over the facies and thickness of the Cambrian sediments. Major faults

may have displacements of the order of several thousand feet and these often

bear close relationships to diapiric structures (Webb, 1958; Coats, 1964). These

intrusive bodies occur along fairly well defined trends particularly in the central

Flinders Ranges, and there is clear evidence from the [facies and thickness of

the Adelaide and Cambrian Systems that the cores were actively rising and

eroded during deposition.

The most significant feature of the Lower Cambrian Series in the Flinders

Ranges is the basinal structure described by Horwitz (1962a) in the Arrowie

area. <A thickness of 12,000-14.000 ft. of Lower Cambrian sediments has been

measured in this region (Tig. 1: 4). This contrasts with the more normal thick-

ness of approximately 2,000 ft. in the stable shelf zones (Fig. 1: 1, 6,8, 11, 12, 13).

Hawker Grove (new name)

The mapping of Lower Cambrian formations in the central Flinders Kanges

inclicates a natural grouping of the units proposed by Daily (1956) from the

Lake Frome region, The Parara Limestone, Bunkers Sandstone and Oraparinna

Shale and also the Narinu Greywacke (new name) are closely related and in

one locality all but the last unit change laterally to the facies of the Wilka-

willina Limestone (seu Fig. 3, point b).

The Hawker Group is defined comprising the seven formations listed above,

There is « distinct mappable contact at the top af the Pound Quartzite which

forms the boundary between the Wilpena and Hawker Groups; and the unit

uverlying the Hawker Group, the Billy Creek Formation, has a sharply defined

base in all areas. Locally, the Billy Creek Formation may be disconfornmable

au) the underlying units,

The geographic name for the Group is taken from the township of Mawker

(3L°53’S.; 138°25°E.).

A representative section for the Hawker Group js Ten Mile Creck south

of Wirrealpa (Fig. 3, XY). which ts the type area of Daily's units (Daily, 1956).

The Parachilna Formation and Narina Greywacke are not developed. Sections

which are convenient for examination aud which show imparfant unils of the

Hawker Group occur at Bunyeroo Gorge (Fig. 4), along ihe east flank of the

Wilson syncline a few miles novth or south of the old town, in the Mernmerna

syncline near the abandoned rail cottages and east of the Big Hill on the Blinmun-

Witrealpa Road. Alsc. the track north-west fram the bore near Old Wirrealpa

provides an instructive section of the upper units.

Howchin (1925) described the Cumbrian exposures in the vicinity of Wilson

and used the term “Wilson Series” although no definition was given — His

sequence as shown in bis seetions (Howehin, 1925, Fig, 6, p, 19) wus. incorrect.

Thus his nit A is variously the Bunyerou Formation (Thomson ef al, 1964)

of the Wilpena Group and the Oraparinna Shale. Although four formations of

the Tlawker Group are now recognized in this area, the name “Wilson” is not

adopted. For cartographic reasons it is desirable to have distinctive initial

letters lor the Group names; thus Wilpena Group, Hawker Granp, Further-

more, the name Wilson's Bluff Limestone (Singleton, 1954) is in common use

in Terliary stratigraphic nomenclature.

The Hawker Group represents ulmost the entire Lower Cambrian Series in

the Flinders Ranges. Glacssner (1963) has discussed the concept of the base

of the Cambrian and he states that there is commonly an interval where dating

is uncertain and that this should be indicated im map legends. However, in the

Flinders Ranges the base of the Parachilna Formation has been adopted as the

top of the Adelaide System (Thomson et ul. L964), and the Patachilna Farma-

lion is arbitearily assigned to the Cambrian, although the first recognizable

Lower Cambrian fossils appear in the Ajax and Wilkuwillina Limestones. The

hase of the Middle Cambrian is considered to fall somewhere within the Billy

Creck Formation (Daily, op. cit. ).

Pavachilna Formation (Glossary, Thomson et al, 1964).

Type Section—South side of Parachilna Creek 2) yards downstream from

the peint where the road from Parachilna to Blinman first enters the creek, The

unit corresponds to the “passage beds” of Mawson (1988), viz. units 28-38,

Thickness; 230 ft. It comprises white argillaccous sandstone with seuttered

pebbles at the base, overlain by 30 ft. of ferruginous weathering sandstone witli

vertical burrows. ‘This bed forms. a prominent marker buth in the Ranges and

at Ediacara (Nixon, 1963), The remainder of the Formation comprises sandy

unils and calcareous silts and shales with minor oolitic limestones. The upper

limit is marked by the appearance of dominant carbonates. In the Parachilna

section the top of the Formation corresponds to the base of Mawsan's unit 39,

comprising 918 £t. of massive, flaggy and oolitic limestones. This unit is referred

to the lower (unnamed) member of the Wilkawillina Limestone,

Iu the Mt. Seott Ranee, Segnit (1939) described the ParachiIna Formaticn

oe unit Ela) as a light grey, caleareons shale 150 f€. in thickness, tying discon-

ormably on the Pound Qnartzite, the hollaws at its base being filled with

arenaccous, material.

In the Nepabunna area, Mawson (1937) did not differentiate the beds with

worm burrows from the Pound Quartzite, but a mappable contact is clear here

as also ut Angepena and in the Arrawie syncline to the south. The Formatiun

reaches its maximum thickness of approximately 1,200 ft. in this area, The unit

diminishes to zero south of Wirrealpa. At Mt. Frome there isa thickness af 15 ft.

and further south quartz-pebble conglomerates vecur in the unit east of Reap-

hook Hill, Mere burrows penetrate into the top of the Pawnd Quartzite but none

originate within this formation, suggesting hiatus before deposition of the

Parachilna Formation..

At Brachina and Bunyeroo, the Formation does not exceed 80 ft. although

thicknesses of several hundred feet oceur in the region about Wilson, Worm

borrows und evidence of worm activity remain a consistent feature of the sand-

stones. Thomson (1962) has recognized the characteristic lithology aud

worn burrows of the Parachilna Formation in the Wilkatana Bore where the

Pound Quartzite is not distinguished.

The burrows have previously been designated Scolithus by the author

{ Dalgarno, 1962) althongh some examples of U-shaped burrows were known,

A critical examination on tle suggestion of M. F. Glaessner has revealed thut

the burrows are better referred to Diplocraterion as the single burrows exposed

in vertical section frequently have a paired shaft on the bedding surface, indicat-

ing the U-form of the burrow.

Wilkawillina Limestone (Daily, 1956).

South of its type section, Wilkawillina Gorge (Ten Mile Creck), the forma-

tion lies with inferred disconformity on the lower (unnamed), reddish member

af the Pound Quartzite (Fig. 3, a). The upper, more resistant member, is absent

along the Bunkers Range northward as far as the Binman-Wirrealpa Road,

bul tu the south of Ten Mile Creek in the vicinity of point ¢ (Fig. 3), it exceeds

1,000 tt. in thickness. Mawson (1939, p, 345) stated that there was no sign of

wiconfurmity, but that there was some evidence of an overlap at the base of

the Cambrian limestone in Wilkawillina Gorge. This is supported by the ohser-

ration hy J. E. Johnson (pers. comm.) at point e, Fig. 3, of fannal ussemblige

two of Daily, which occurs at the top of the Wilkawillina Limestone in its type

seetlou, lying directly on the upper member of the Pound Quartzite.

The name Wilkawilling Limestone is uscd in a broad way in this paper for

the Lower Carobrian limestones im the Flinders: Ranges, other thar mu the Mut.

Seett area, which either occur stratigraphically below the Parara Limestone ur

STRATIGRAPHY OF THE FLINDERS RANGES 136

represent continued deposition of thick-bedded Archaeocyatha limestones, There

is considerable variation in lithology but essentially two members may he recog-

nized. The lower is poorly fossiliferous with arenaceous and shaley bands, the

limestones being relatively thinly bedded, dolomitic and frequently oolitic.

Algal-rich units are notable in the Brachina, Mernmerna and Chase Range areas

near the top of this sequence, The upper member is best developed in the

stable shelf zone of the central Flinders Ranges and comprises relatively pure

and light coloured foassiliferous limestones in very thick beds, In the basinal

areas south of Mernmerna and north of Wirrealpa, mottled blue-grey massive

and thick-bedded limestones may be developed at the top.

The areas in which archaeocyathids ure best developed are the Wilka-

willina Gorge and immediately to the sonth, the Brachina area and parts of the

Mt, Scott-Ajax region.

A mile to the south of its type section, the Wilkawillina Limestone facies

inter-tongues with the Parara Limestone, Bunkers Sandstone and Oraparinna

Shale (assemblage nine) so that the npper boundary of the formation is markedly

time transgressive, varving between faunal assemblages nine and two within a

few miles. The name Ajax Limestone (Daily, 1956) is applied to the equiva-

lents of the Wilkawillina Limestone (this paper) in the Mt. Scott Runge arca.

Pararud Linestotie

The name Parara Limestone was extended fromm Yorke Peninsula by Daily

(1956), In the Ten Mile Creek sevtion the formation comprises flaggy lime-

stones and dark calcareous shales, In the central Flinders Ranges it is lithologic-

ally distinct from the underlying massive limestune and the contact is normally

quite sharp. In the basinal areas, such as about Hawker and Arrowie, a shale

unit is common at the base. New nomenclature may be necessary later for

notable caleareous und carbonaceous shale units within the formation in the

ares i areas, The most common fossils are fragmented trilobites and archaeo-

cyathids.

The unit is discontinuous in the central Flinders Ranges, being absent from

the Mt. Frome, Reaphook, Brachina and Mt. Scott areas. Daily (op.cit.) records

fannal assemblages three and four, typical of the Parara Limestone, from the

Ajax Limestone at Mt. Scott, bnt the Parara facies is not developed. A similar

situation may apply in the other areas; thus at Reaphook faunal assemblage two

apparently occurs In the middle part of the Wilkawillina Limestone, whereas it

vecurs at the top at Ten Mile Creek.

Near Baleoracana Creck the Parara Limestone is lenticular and does not

exceed 20) ft. in thickness, but aorth of the Wirrealpa Diapir and in the Arrowic

area, it reaches 5,000 ft. North of Bunyeroo Creek, the formation wedges out

against a fault which controlled deposition (Fig. 4, point a).

Bunkers Sandstone (Daily, 1956).

This formation attains its thickest development (600 ft.) in its type section

north of Ten Mile Creek, It wedges out within a few miles to the north and

south and is lenticular between the type orca and Point Well. Ir does not

exceed 150 ft. in thickness in these oceurrences and there are no other develop-

ments of the formation in the Flinders Ranges. It was recorded from Reaphowk

(Dalgarno aud Johnson, 1963) but subsequent work has shown that the sand-

stone overlying the Wilkawillina Limestone in that area represents the lower

part of the Billy Creek Formation.

In certain areas the Bunkers Sandstone interdigitates with the Parara Lime-

stone and Oraparinna Shale, e.g. Fig. 3, ¢.

Oreparinne Shale (Daily, 1956)

The Oraparinna Shale is a green, very thinly bedded silty shale which

normally breaks with a conchoidal fracture. Immediately north of its type

section, the Oraparinna Shale rests on the Parara Limestone (Fig, 3, ¢c) and

STRATIGRAPHY OF TIME FLINDERS RANGES 137

it uppears to Wansgress this wit on lo the Wilkawillina Limestone in the yicinity

wf point d (Fig, 3). In the occurrences about Hawker the formation has an

apparent transitional contact with the underlying Parara Limestone. North of

Bunyervo the Oraparinna Shale overlaps the Parara Limestone on to the Wilka-

willina Limestone (Fig. 4, b) and then thins to zera, It oceurs above shaley

’arara Limestone in a local area east of Nilpena Siding but neither facies is

developed in the Mt. Scott section nor ta the north of Brachina Creek,

The Oraparinna Shale is not developed in the Mt, Frome and Reaphook

ureas and it is missing for a distance of approximately two milcs along the

Bunkers Range in the vicinity of Balcoracany Creek. It is alsa absent immie-

Giately north of Wirrealpa H.S., but it is present further west, both north and

south of the Wirrealpa Diapir, where it is interbedded with more silty units,

In this region it apparently interdigitates with the Narina Greywacke. The Ora-

pirmans Shale carries trilohites together with brachiopods and simall archage-

cynthids,

of the Cambrian sequence. It comprises’ interbedded grey silts and grecnish

ereywacke sandstones with minor calcareous units. The formation is truncated

hy a Fault at its upper limit in the type section. In the only other important

exposure near Point Well the top of the unit has been removed by ergsion sv

that nowhere is its relationship to the Billy Creek Formation observed. The

contact with the underlying Oraparinna Shale is transitional. A minimum

thickness of 4,500 ft, is given for the unit on the Arrowie Sheet (Horwitz, op.vit.);

however, Fig. 2 shows only 2,000 ft.

Buay Carex Formation

In the central Flinders Ranges there is an important marker bed above the

Oraparinna Shale which is notable as a ridge former. It comprises a unit of

Alaggy and finely laminated, buff-weathering dolomitic limestone approximately

10 ft. in thickness and it is commonly underlain by a thin, brown, tossiliferous

limestone which was chosen by Dalgarno and Johnson (1962; 1963, section 3)

as the base of the Billy Creek Formation.

In the vicinity of Ten Mile Creck the dolomite follows rubbly limestones

at the top of the Oraparinna Shale and it has been mapped te within a quarter

mile of Balcoracana Creek. B. Daily and K, Pocack (pers. vomm.) have recently

ubserved the unit immediately north of Baleoracana Creek and below it is a thin

development of Oraparinna Shale. However, one mile beyond this both units

ure considered to be absent and the marker dolomite is not known beyond this

area. East of Ten Mile Creck this unit occur above massive Archarorryatha

limestones which represent a tongue from a biostromal development (Fig. 3, b),

Fig. 4. Cambrian sequence near Bunyeroo Gorge.

On the western side of the Range the laminated dolomite and fossiliferous

bed are known north of Brachina lying directly on the Wilkawillina Limestone.

They are prominent at Bunyeroo (Fig. 4, ¢) and in the small syncline to the

south. The same marker beds occur above the Oraparinna Shale in the Mern-

merna area and alsu in the keel of the syncline four miles north-east of Wilson.

The Billy Creek Formation is dominantly red-brown micaceous shale with

a lower member comprising alternating red and grey-green silts with minor

sandy bands and thin dolomitic beds. This is separated from the upper portion

of the Formation in the Ten Mile Creek-Balcoracana area by a fairly persistent

dolomite associated with three tuffaceous units, The latter are a characteristic

salmon pink colour and were first collected by B, P, Thomson from Bewthina

and Ten Mile Creeks, Subsequently tuflaceous units have been fuund at Bun-

yeroo, Wirrealpa and along the entire length of the Bunkers Hange te south

af the type section, where they occur in Mawson's anits 41-43 (Mawson, 1939 )-

They occur also at Reaphaok and Mt, Frome, but are not known in the Billy

Creek Formation at Mt. Scott.

The uppermost units of the Billy Creek Formation are red-brown micaccous

sandstones very similar in character to the Moodlatana Forimation, The Billy

Creek Formation as a whole is considered to represent an entircly different

phase of deposition from the Hawker Group and shows close affinities to the

Lake Frome Croup. It is known only in the areas of relatively thin Lower

Cambrian sedimentation, but it is inferred to represent a phase of general

regression with minor marine Huctuations,

It is probable that the Billy Creek Formation is disconformable py the

Ajax Limestone at Mt. Scott where faunal assemblages six to nine are absent

(Daily, 1956). North of Brachina Creek the basal dolomitic unit of the Billy

Creek Formation lies directly on the Wilkawillina Limestone facies so thal a

similar relationship may exist lere, although biostratigraphic information is

Jacking. South af Ten Mile Creek the Formation onlaps on to the Wilka-

willina Limestone (see below) and may actually be in contact with the Pound

Quartzite below alluvial cover, East of Reaphook Ilill a prominent sandy unit

oceurs low in the Billy Creek Formation, but this is uot a basal unit, as sandy

limestones at the top of the Wilkawillina Limestone are overlain with a sharp

contact by red silts in the intervening valley. Facies cliunges do oceur along

strike in the basal beds of the Billy Creek Formation, particularly on the north

side of a small obliqne fault, A disconformity of small importance is inferred

but faunal studies have not been done,

Just to the south of Balcoracana Creek halite casts vccur at the tup of a

6 ft. calcareous sandstone above the basal dolomitic unit of the Billy Creek

Formation, indicating emergence during the early part of its deposition. Halite

casts nnd raindrop impressions have been noted throughout the formation and

trilobites are rare. No other marine furms have been reported.

A suite of trilobites was collected by J. E. Johnson and the author Ayan

approximately 25 ft. below the lowest of three tnffaceous bands in the lower

part of the Billy Creek Formation near Baleutacana Creek. They are at present

heing described by K, Pocock and B. Daily of the University of Adclaide,

Worreanpa Tawrsronn (Daily, 1956)

The Wirrealpa Limestone is known in all areas, with the exception of

Heuplivok, in which the Billy Creek Formation occurs. It thus forms a usetul

datum for discussion of the Cambrian in the Flinders Ranyes. Its thickness

on the western side of the range is approximately 300 ft.. whereas in the Ten

Mile Creek-Wirrealpa region, it is 350-400 ft. thick. The lithology of the noit

varics little, there being a fairly persistent massive dolomitic unit at the base

which contains siderite and flecks of galena, Commonly a few feet above this,

in thin-bedded limestones, is a persistent bed containing broken fragments aud

spines of Redlichia. Brachiopods and Girtanella are abundant higher in the

unil ju inare shaley and rubbly limestones.

140 C, R. DALGARNG

The unit occurs west of Wertaloona HLS. where it has 4 facies similar to

the Areona Creek Limestone (Daily, op,cit.) ou the opposite side of tle Ranges.

The sequence here is faulted at the base against the Adelaide System, but red

beds referable to the Billy Creek Formation do oceur. This is the only evidence

ot the persistence of these two formations in the deeper hasin area.

Lake Frome Grotr (Daily, 1956)

The Moodlatana Formation overlies the Aroona Creck Limestone at Mt.

Seott and the Wirrealpa Limestone at Brachina and Bunyeroo and m the Wir-

realpa area. Jt also outcrops east of Mt. Frome and south-west of Wertaloona.

In all areas the contact is conformable ane apparently represents a return to

deltaic conditions similar to those of the top of the Billy Creek Formation. Two

cherty, petroliterous-smelling dolomitic limestones near the base of the unit are

persistent marker beds on the western side of the Ranges.

Conditions appeur to have been uniform across the present Ranges during

deposition of the Balcuracana Formation which is a repetitively bedded unit of

thin dolomitic limestones and red-green micaceons silts, probably representing

enclosed basin conditions. This unit together with the overlying terrestrial-

deltaic sandstone (unnamed) is known in only three areas, viz.. north ot

Bunyeroo Creek to Commodore on the west side of the Range, in the Grind-

stone Range area and south-west of Wertaloona. The Grindstone Range Sand-

stone, of deltaic character, is known only in the latter two areas.

The entire sequence {rom the base of the Billy Creek Formation through

to the Crindstone Range Sandstone, totalling 12,000 ft, appears to show ne

significant break in deposition, Daily (op.cit,) considers the Lake Frome Cron

to be contained within the Middle Cambrian,

DISCUSSION

Ten Mite Crrek Locatiry

Mapping of the Ten Mile Creek area showed that the structural settine

of Daily’s standard section is a graben developed above the Oraparimna diappir.

The structure is related to diapirie uplift which took place during deposition

of the upper Marinoan and Lower Cambrian. Reterence to Fig. 3 shows the

relative displacement of the Umberatanu Group (Coats in Thomson et al., 1964),

Wilpena Group, Hawker Gronp and the Middle Cambrian Wirrealpa Limestone.

ln detail, the upper member of the Pound Quartzite is absent within the

graben and for more than five miles to the north, although it is very stronuuly

represented to the south of the point b. The Parachilna Formation is absent

from the whole region so that the Wilkawillina Limestone rests disconformably

on the Pound Quartzite.

For the Hawker Group, the thickness in the central part of the graben is

4,100 ft., whereas at point d, the unit is approximately 1,500 ft. and at point e,

only 200 ft. Here the basal limestones uppear te represent faunal assemblage

two of Daily so that the lower part of the Wilkawillina Limestone is absent.

The significant feature of the mapping is the interdigitation of the units of the

Hawker Group at points h. c and d. See Vig, 3 and Plate 1, Figs. 1 and 2.

STRATIGRAPHY OF TIIE FLINDERS RANGES 141

The deyelopment of Wilkawillina Limestone at point b constitutes a bio-

strome controlled by the actively subsiding fault bounding the graben. The

entire structure aud the processes which imterfinger with the basinal facies are

comprised of richly fossiliferons bedded archaeocyathid limestones similar to

the Wilkawillina Limestone in its type section. No detailed stidy has been

mide of the faunas or rovk types, but the prelimimary mapping shows that the

biostrome persisted throughout much of the Lower Cambrian as a localized

urea where growth of carbonate secreting organisms, notably Archaeocyatha,

flourished.

The Billy Creek Formation is 3,300 ft, in thickness in the graben and to

the north (Mawson, 1939, units 39-46): however, the formation is reduced near

paint e to approximately 1,800 ft. Here the upper part of the Formation (viz.

Mawson’s units 44-46) appear to transgress the Wilkawillina Limestone, but it

is not seen in contact with the Pound Quartzite as the red shales do not outcrop

south of point ec, The basal marker bed of the Billy Creek Formation is not

known east of the point b and the three tuffaceous beds and associated dolomite

ave not present beyond the major fault.

Bunyvernoo Reciox

The features of the Hawker Group ihistrated by Fig. 4 are the restriction

of the Parara Limestone facies to the zone south of the fault (point a) and the

tongue of Oraparinna Shale which extends northward to point b. The upper

part of the Wilkawillina Limestone about point b and further north in the vicinity

of Brachina Gorge is extremely rich in archacocyathids. Southward, nearer the

fault, brachiopods become very abundant. In Bnnyeroo Gorge arehaeocyathids

are relatively less comraon and brachiopods and trilobite fragments are the im-

portant fossils at the top of the mnit, The faunal assemblages have not been

determined for the sections north and south of the fault so that two interpre-

tations are possible.

1, Archaeacyatha were abundant north of the fault (point b) prior to the

development of the Parara Limestone and Oraparinna Shale, but then deposi-

tion ceased in this area until the basal member of the Billy Creek Formation

(hig. 3, ©) was deposited..

2, The lateral equivalents of the Parara Limestone and Oraparinna Shale

are represented north of the fault by a slowly accumulated binstromal archaeo

evathid development.

This situation exemplifies the problem of interpreting geological events

without the evidence provided by fossils, which in this area, are abundant but

unstuclied,

GEOLOGICAL, HISTORY

Conditions in the Adelaide Geosyncline during deposition of the upper

part of the Wilpena Group (late Marinoan) appear to have been generally

marine, with thinly-hedded silts and marls deposited. Prior to the Cambrian,

rejuvenated erosion and marine regression resulted in widespread deltaic and

shallow marine conditions over the area of the present Ranyes (Pound Quartzite )

and on the Stuart Shelf to the west of Lake Torrens broad areas were covered

hy clasties of the Tent Hill Formation.

142 C. BR. DALCARNO

A fairly clearly defined sedimentary change related to renewed transgressinn

acourred at the base of the Hawker Group. A littoral er shallow marine sand-

stone with scattered pebbles at the base and abundant vertical burrows was

deposited over a wide area (Parachilna Formation). This development is:

absent from the southern part of the Bunkers Range and the Cambrian limestones

lie disconformably on the lower member of the Pound Quartzite, On the shelf

wea near Andamooka, Segnit (1939) described transgressive relationships at

the base of the carbonates,

Over the greater part of the area discussed the Cambrian carbonate followed

transitinmually the arenaceous units. Dolomitic limestones were developed on the

stable shelf in the main transgressive phase and oolitic and algal beds were

cammon. In the middle part of the Lower Cambrian clean limestones and

archaeocyathid biostromes were widespread but were less well developed in

the hasinal zone to the north-east.

Subsidence adjacent to minor faults resulted in limited thicknesses of thin-

bedded limestones on the stable shelf (Parara Limestone) but limestones of the

same character accumulated to thicknesses as great us 5,000 ft, in the unstable

vanes. Adjacent to the hinge line above the Wirrealpa Diapir (Fig. 2, 7) these

husiual limestones interdigitated with sandy units (Bunkers Sandstone),

In the upper part of the Lower Cambrian green silts and shales (Ora-

pariinw Shale) overlapped the thin developments of Parara Limestone in the

wcritral Flinders Ranges on to the clean shelf limestones. Deposition may have

ceased Ipcally in the western und central provinces, but clean biostromal lime-

stones continued to form slowly in local areas, e.g. south of Ten Mile Creek and

pussildly near Brachina.

Close to the hinge line at the Wirrealpa Diapir silty interbeds developed

in the shales und more rapid deposition occurred immediately to the north. A

clastic unit several thousand fect in thickness (Narina Greywacke) was de-

posited in the main basin area during an interval of non-deposition over much

of the central Vlinders Ranges.

Yollowing deposition of the Hawker Group, the ved argillites of the Billy

Creek Formation appear to represent a mud flat environment with occasional

incursions Of the sea, indicating regression with large supplies of fine terrigenous

elastics. Verv small scale oscillation ripple marks, halite pseudomerphs and

niiudeop impressions are environmental indicators. The last phase of deposition

in this wnitis more arenaccous with cross-hedding, suggesting a deltaic environ-

ment, Thin tullaceaus bands in the lower part of the Formation may be related

ta yuleanism in the province to the east.

Shallow marine transyression over a broad stable shelf resulted in the

Middle Cambrian Wirrealpa and Arvona Creek Limestones, which were clearly

cuntingos over much of the northern and central Flinders Ranges, The basal

unit may have been a chemical precipitate of an enclosed basin but the trilobite

breccias, beachiopod-rich bands and rubbly limestones of the upper part of the

unit ds the ventral areas, suggest open, shallow water environments.

The Middle Cambrian marine beds and the inderlying Billy Creek lorma-

tion have yenerally been removed by erosion trom the areas of thicker deposi:

thon but both units are considered to have been widely distributed.

STRATIGRAPHY OF THE FLINDERS KANGES 145

The environment of deposition of the Lake Frome Group alternated between

deltaic, enclosed basin and terrestria) conditions and these mnst be regarded

as the final phases of deposition in the Adelaide Geosynclinc. The Lake Frome

Group is knuwn in only four areas, but it is clear that the lower units at least

extended without lithological change across the present Flinders Ranges.

The broad folding and final movements of the larger faults of the Flinders

Ranges are presumed to have taken place in the late Cambrian and Ordovician.

There is no evidence of diapirism within the Ranges later than the upper Lower

Cambrian, the only evidence of later movements heing provided by the infolded

Triassic coal basins.

The present topygraphy of the Ranges is regarded as due to broad arching

during the Tertiary and Quaternary which has resulted in the young dissecte

uravels of the Range margins and the shallow dipping duricrusted sands which

dip under the Lake Frame and Torrens Plains. in the latitude of Blinmun.

SUMMARY

The larval stages of Cybister tripunctatus (Oliv.), C. godeffroyi. Weh.,

Homoeodytes atratus (Fab) and Hyderodes shuckardi Hope are described, ‘The

larvae of Homocodytes scutellaris (Gerni.) ure redeseribed in greater detail than

in the original description,

Descriptions of all instars except the first uf MH. atreéuy are inclnded,

During a recent trip through Eastern and Northern Australia, 1 collected

several Jarge Dytiscid laryae belonging to the Oybisterini. Among them were

two specimens of a Homocodytes Reg. other than H. seutellaris (Germ.) the larva

of which is known (Watts, 1963). As H. atratus ( Fab.) is the only other species

of this genus in Australia and an adult specimen was. taken at the same time as

the larvae, it seems certain that these larvae belong to H. atratus. The collec-

tion also contained larvae of two species of Gybister Curt., one of which, C,

tripunctatus (Oliv.) was identified by breeding out the adult. Larvae of the

other species have been assigned to C. zodeffroyi Wel., the only other Cybister,

other than the following, recorded from Australia. Blackburn, in 1888, de-

scribed a Cybister under the name of CG. granulatus. 1 have seen the co-type

and specimens identified by Blackburn in the $A, Museum and consider that

they represent the more granulated forms of C. tripunctaius, there being an

unbroken gradient from smooth to rough elytra in this species. In addition, the

larvae in question are much larger than those of C. tripunetatus which is the

same size as C. granulatis,

Xambeu (1904) described a larva from Madagascar under the name of

C. tripunctalus. The description of the colour does not match that of Australian

specimens and the fact that the sive of the larva he described was a great deal

larger than the true C, fripunctatus (length 80 mm as against 57 mm) indicates

that he was mistaken in assigning his larva (which he did not rear) to this species.

In September, 1962, T visited a pool in a slowly flowing creek at Williams-

town, S.A., and found it to contain a large number of Dytiscini larvac, Several

at the larger larvae were bred aut and proved, as expected, to belong to

Hyderades shuckardit Hope. A month later I made a trip to the same pool in

an attempt to collect adults. However, no specimens of any stage were found.

As it was hardly likelv that all the larvae present one month earlier had pupated,

mauy being first instars, it seems likely that the whole population had heen

destroyed in the meantime. Further trips also produced no specimens, nor had

1 taken the species there on numerous previous occasions stretching hack ayer

twin years.

This paper coutains descriptions of the larvae of the aboye four species 2s

well as a redescription of those of H. scutellaris made desirable by the discovery

of thé larvae of closely related species. Hyderodes Hope is endemic to Australia;

H. shuckardi is found in 8.R, Australia, Tastnania (Sharp, 1882) aud $.W. Aus-

tralia (Regimbart, 1908), although the latter reference inight in reality be to

I, erassus Sharp. Two other specios, H. crassus.and H. collaris Sharp, have bee

deserihed from N.W. Australia, but are very rare in collections. C. godeffroyi

occurs in the wetter areas of N, Australia; C, fipunetatus occurs through most of

Australia apart from the more southern areas, having outside Australia a wide

distribution threugh S.E. Asia, India, Africa and occasionally S$. Europe, HA

seutellaris is common in southern Australia including Tasmania; 1, afratus ts

more tropical in distribution, oceurring in the coastal regions of Queensland

and northern Australia, The only other species of the genus IH, hwokeri (Wh. }

oveurs, together with the introduced H. seutellaris, in Neve Zealand.

{In identifying the larvae of Cybister and Humoeodytes it is helptul ta know

the instars of the specimens involved, A good clue to this is the relative lengths

of the third and fourth joints of the labial palpi: in the 3rd instar the fourth

joint is the smaller, in the 2nd instar it is either a little longer or roughly equal

te the third joint, and in the 1st instar the fourth is the greater, Furthermure,

Ist iustar larvae can be separated from alder instars hy the lack of a row of

setae hehind the occular arca and also by the lack of ventral spines on the

posterive adborminal segments present in older instars, although often few a

2nd instar larvae.

In my key to the larvae of Australian Dytiscids (Watts, 1963) Hyderodes is

not included." It will run to Wydaticus Leach from which it can be distinguished

by the Jack of a ligula and the presence of swinnning hairs ou the cerci.

dentate, but not to the same extent as in Momweadytes. The cerci are not as

reduced, although those of H. atratus approach those of Cybister and they are

placed much farther forward than in Cybister. The neck is short and is sunk

into the prothorax, whereas in Cybister it is longer and is not covered by the

prothorax. The mandibles lack the apical girdle of setac found in Cybister. (In

a previous paper (Watts, 1963) before I had seen specimens of Cybister I gave

as a distinguishing character the Iength of the ligula which in fact does not

differ much between the gencra.)

Larvae of this species can be separated from thase of H. scutellaris by their

more reduced cerei, their narrow elongated head and the fact that the lateral

lobes of the clypens touch the middle lobe. There is a possibility that I have

assigned these two spocimens ta the wrong instars: they may prove lo be the

1st and 2nd instars,

Hyderodes Nope

This genus is most closely related to Dytiscus L. of the Northern [lemisphere,

the two forming a well-marked tribe, the larvae characterised by their entire

clypcus, cerci and abdominal segments 7 and 8 with swimming hairs, and the

lack of a ligula. The larvae of Hyderades differ from those of Dytiscus most notice-

ably in the following characters: Hyderodes has temporal spines (except in the

Ist instar), spines ou the ventral surface of the head, two rows of short spines

along the bottom edge of claws and has no row of long setae on the inner edge

of the cerci. (In many species af Dytisens the number of setae on the inner

edge of the cerci are reduced to only two apical ones in Ist instar larvae. )

TWO TRICHOSTRONGYLE NEMATODES FROM A MARMOSET

BY PATRICA M. MAWSON

Summary

A number of worms were taken from the small intestine of Callithrix jucchus, recently imported

(from the Antwerp Zoo) for the Adelaide Zoological Gardens. They were collected and fixed in the

Institute of Medical and Veterinary Science (Adelaide) and given to me through the courtesy of

Alan W. Banks of that Institute. Mr. Banks noted that in life "the largest worms were red and more

or less straight, the smaller ones coiled". The species have been identified us Molineus elegans

Travassos (the larger) and Longistriata dubia Travassos (the coiled), both new records for the

marmoset. Travassos noted ( 1937, p. 77) that these two species occurred together in the common

type host, Saimiri sciurea.

The measurements and appearance of the specimens from the marmoset

agree generally with the description af the types, although the position of the

cervical groove and the excretory pore, and of the cervical papillae, are more

posterior compared to that of the nerve ring and to the length of the ocsophagus,

The arrangement of these resembles more that in M. torulosus (Molin), Ie is,

however, distinguished from M, lorulosus by the barbed inner branches of the

spicules, the longer externo-dorsal ray, the presence of a patch of fine hooks

on the inner surface of the lateral lobes of the bursa, and the shorter ovejectors,

Longistriata dubia closely resembles L. argentina Freitas, Lent and Almeida.

The latter has been recorded once, from a rodent, Holochilus balnearum (F, L, A

1937, p. 198), the former five times, three records from primates (Travassos,

1921, p. 367, from Saimiri sciurea; 1937, p. 329, from Alouta caraya; Cameron,

1923, p. 71, from Saimiri sciurea) and twice from a lagomorph, Romerolagus

diazi (Bravo Hollis, 1950, p. 114; Aguillar, 1958, p. 45). A proper comparison

of the descriptions given by these atithors is impossible, as the positions of nerve

ave described by Travassos as enlarged and enclosed in a membrane, but are

shown by other authors as simple. L. dubia of Brayo Hollis is shown with the

excretury pore in what seems to be a groove around the body, In the specimens

now identified as L. dubia no such groove is present. The spicules each end in

a tiny hook which in Jateral view gives a swollen appearance to the tips. In

some male specimens a very lightly chitinised gubernaculum and telamon,

absent in L, dubia, are visible, as figured for L, argentina.

The tail of the female ends in a sharp point, whereas those figured in all

records quoted above arc rather rounded; the suwh-cuticular tissue, however,

shows subterminal knobs as figured by Trayassos, ‘lhe eggs are larger in relation

to the bedy width than in other descriptions, but it has becn noticed that in

Longistriata spp. the posterior end of the female enlarges with age.

It is considered that the specimens from the marmoset belong to L. duhia.

Whether L. argentina should be considered a synonym of L. dubia, and, if not,

whether the specimens identificd by Brave Hollis and by Aguillar belong to

L. dubia or to L. argentina, can only be ascertained by re-examination of the

material in question.

Meusurements of the specimens from the marmosct are given in Table 1.

THE PROCESS OF FERTILIZATION IN THE SPINY LOBSTER

JASIJS LALANDEI (EL MILNE-EDWARDS)

BY D. R. FIELDER

Summary

The mechanism of copulation in Jams lalandei (H. Milne-Edwards) is discussed by comparing the

reproductive organs with those of Panulirus cygnus (George). The structure of the fifth pereiopods

and thoracic sterna of the female 1. lalandei indicate;; that the deposition of external

spermatophores is unlikely. The male genital apertures of 1. lalandei are also not well adapted for

depositing external spermatophores as they are in P. cygnus. The introduction of internal therefore

the alternative.

An hypothesis is put forward, describing a potential intromittent organ in male J. lalandei to support

the assumption of internal fertilization.

THE PROCESS OF FERTILIZATION IN THE SPINY LOBSTER

JASUS LALANDEI (IL. Milne-Edwards)

By D. BR. Frecprer®

(Communicated by 1, M. Thomas)

[Read 13 August 1964]

SUMMARY

The mechanism of copulation in Jusus lalandei (H. Milne-Edwards) is dis-

cussed) by comparing the reproductive organs with those of Panulirus cygnns

(George), The structure of the fifth pereiopods and thoracic sterna of the female

{. lalandei indicates that the ceposition of external spermatophores is unlikely,

The male genital apertures of J. lalande? are also not well adapted tor depositing

extérnal spermatophores uy they ace in P. cygznus. The introduction of internal

sperinalophores is: therefore the alternative.

An hypothesis is put forward, describing a patential intromittenl orvan

in male J. lalandet to support the assumption of internal fertilization.

INTRODUCTION

The mechanisin of fertilization has been deseribed for several specics of

Panulirus; Panulirus interruptus (Randall), Allen (1916), Lindberg (1955);

Panulirus pencillatus (Oliver), Matthews (1951); Panulirus cygnus (George);

Sheard (1949), George (1957), Panulirus argus (Latreille), Walton Smith

(1959). In cach case fertilization occurs in the same manner. The male deposits

a puity-like spermatophore on the sternum of the female, posterior to the genital

apertures, some time before the ega@s are released, The spermatophore, initially

soft and light in colour, hardens and turns black. LDygs are said to be fertilized

externally by sperm released frum the spermatophore by the chela of the fifth

legs of the female. [loweyer, the method of copulation has not been verified, nor

is tt known with certainty at what stage of monlt copulation occurs,

Yon Bonde (1936) described the act of mating for Jasus lalandei (A. Milne-

Edwards) from observations made on captive animals. He found that the male

turns a newly moulted female on her back so that their sterna are closely apposed,

His conclusion that fertilization is internal is based on the following statement,

that “the spermatophores are extruded and appear to make their way through

the female genital apertures and so into the oviducts where fertilization takes

place at their upper ends”, Since no mention is made of actually finding sperma-

tophores in the oviduets or failing to find them externally it must be taken thal

the above statement is an assumption,

Initial observation of external genitalia during this present investigation

indicated that internal fertilization was difficult mechanically due to. their rela-

live positions and difference in size between the sexes. Copulation was nol

observed during observation of captive animals over threc years, precluding

direct description, The prublem was therefore approached indirectly by com-

paring the external genitalia of P. eyentus from which the process of fertilization

is known, with those of J. Jalandei. From this comparison it was hoped that an

hypothesis for the method of fertilization, based on more than assumption, ciuld

be erected.

THE FEMALE

(a) The Fifth Walking Leg:—The fifth walking legs of P. cygnus and J,

lalandei are compared in Fig. 1, In P. cygnus a short, stout arm projects later-

ally from the base of the dactylopodite, which is capable of closing agwinst a

stout extension of the propodite. The dactylopodite therefore forms a strong

chela capable of pinching as well as scratching. This chela is used tu break the

spermatophore and then gouge it open to release sperm. In J. lalandei the dacty-

Jopodite has no lateral arm and is similar to those of the other walking legs. A

spine projects from the distal end of the propodite, which is apposed to the

dactylopodite forming u chela. The spine of the propodite is much smaller

than the dactylopadite and is attached by a thick membrane of chitin. The

chela is therefore not very strong as the spine of the propodite does not form a

solid base to the dactylopedite. Such a chela is not suited for pinching or

breaking and is probably used to comb and clean the ovigerous setae of the

pleopods.

Fig, 1, The fifth chelate pereiopods of (1) P. cygnus aml (2) J. lalandei,

(b) The Last Two Thoracic Sterna:—The last two thoracic sterna of P.

cygnus have a smooth hairless area, presumably for the reception of sperma-

tophores. This area is covered by tufts of short hairs in J. lalandei indicating

that deposition of an external spermatophore is unlikely,

(c) The Genital Apertures:—Both specics have similar genital apertures.

The rim of the aperture is raised and circular in shape. The actual opening is

situated on the inner side and extends as a crescent-like slit around half of the

circumference. The remaining area inside the rim is Aled with a chitinous

membrine, which can be inverted to form a circular opening. This membrane

is quite soft and easily inverted in J, lalandei, but is inverted with difficulty in

P. cyenus. The diameter of apertures in mature animals is 2 to 3.mm in J. lalandei

and 3 to 4 mm in P. cygnus.

TERTILIZATION (N TUR SPINY LOBSTER 163

Tig Mane

The Genital Apertures (Fig. 2):—The genital aperture of P. cygnus has the

form of an oval saucer, The actnal epening to the vas deferens is slit-like and

situated on the inner side of the sancer. The remaining area inside the saucer

is filled with a chitinous membrane in the form of a loosely coiled tube ending

ina spine. The spine is free and the tube is capable of erection. Normally, the

tube is eviled so that the spine effectively closes the aperture. The tube is

musenlar and is probably capable of autonomous movement. Its probable

function is to direct the placement of the spermatophore. Movement of the

fitth legs moves the aperture in an are, accounting in part for the bilateral

symmetry of the spermatophore. Apertures of mature animals may be more than

13 mm in diameter.

The genital aperture of J. lelandei ts much smaller than that af P. eyynus,

heing as small as 3 mm in diameter at first maturity. The shape is similar to the

female aperture, the actual opening extending in an are around the inner rim.

The chitinous membrane filling the remaining area is folded and shaped to form

a tongue-like flap, which normally closes the opening, It is unlikely that such

an aperture could extrude a speanatophore similar to that of P. eyenus.

Tt ean be seen from comparison, of external genitalia that the chelate fifth

legs of female J, lalandet are poorly adapted to break open external spermato-

phores, In fact, it is unlikely that external spermatophores could be attached

suecessfully to the sterna of female J, lalandei. The soft nature of the female

itperture in J, lalandei also indieates the possibility nf introducing a sperma-

tophore internally.

The large male genital apertures in P. cyguns would allow large quantities

of spermatophoric material to be eatruded. Their construction also allows the

spermatophore to be directed gver a relatively large area reducing its thickness.

A thin spermatophore would be yvouged more efficiently than a thick one, with

better release of sperm. It is doubtful whether the smaller size of the male

genital aperture in J, /alandei would allow the large amount of material neces-

sary to form an external spermatuphore to be extruded.

Most aspects of the external anatomy of J, lalandei indicate poor adaptatiou

for external fertilization, If fertilization is internal, the absence of a long intro-

mittent organ and the small size of the apertures introduces the problem of

hew males can locute the female aperture for efficient transfer of spermatophores.

In an attempt to answer this question, a detailed examination of the male genital

aperture was made.

Wt has been stated that the tengue-like flap of the male genital aperture

normally closes the aperture, llowever, this fap is capable of erection and

may project more than Smut in ktrge mules. This observation introduced the

possibility that the flap of male genital apertures could be used to locate female

apertures, The validity of this sugyestion appeared to lie in the mechanism of

erection, The fact that most flaps were observed in the distended condition

during breeding seasons indicated they were connected fimctionally with copu-

lation.

The structure of the male genital aperture was therefore studied from

transverse sections. Several male genital apertures were excised with some

underlying muscle and a short length of vas deferens, and fixed in Gilson’s fluid.

The acetic acid of this Axative decaleificd the skeleton. which was softened

164 D. R. FIELDER

further with 8 per cent phenol in 75 per cent methyl alcohol. After embedding

in paraffin wax, m.p, 58°C., serial transverse sections 15y. thick were cut. Sections

were stained with Delafield’s haematoxylin (Harris modification) and eosin,

The flap had no muscle-attachment, eliminating the possibility of erection

through contraction of muscles. The underlying tissues contained large blood

spaces, suggesting the flap was distended by an increase in blood-pressure. It

has been suggested by Von Bonde (1936), that mating occurs a few weeks

following moulting by the male. Since increase in size at moult is caused

primarily by an increase in tissue-fluid it is possible that erection of the flap

is a consequence of moulting. Von Bonde also stated that the female moulted

a few hours prior to mating. At this stage the skeleton is very soft and the

ehitinous membrane of the female aperture would be inverted easily, This

would therefore be the best time for the male to locate the female apertures

and maintain its position by insertion of the genital flaps.

Examinatiin of the oviduct failed to reveal a dilatation or sac that could

be used as 4 seminal vesicle, Without such a vesicle it was difficult to sce how

fertilization could oeeur in the oviduct. Even ullowing for stretching of the

aviduet it would be much smaller than the corresponding vas deferens and it

is doubttul whether it could hokd the same amount of spermatophoric material,

Tt was also difficult to see how sufficient of the spermatophore was retained to

fectilize all egus after ovulation had begun,

It has been stated previously (Tielder, 1964) that the oviduct is lined with

high columnar epithelium, which is folited to form villi. In many cases adjacent

villi formed sae-like channels. Apart from secreting a lubricating Huid or von-

tibuting to the egg-shell, it is difficult ta see the significance of villi in the ovi-

duct, One other possible function of villi would be to retain sperm, which would

fertilize the eggs as they passed down the oviduct. This could occur only if

some of the matrix of the spertnitephore was removed and sperm concentrated

hetween the villi of the oviduct. A final comparison was made between the

structure of the sperm-mass ad vas deferens of J. lalandei and P. pencillatus,

The purpose of this comparison was to determine whether the spermatophore

ot J, ldlandei was more likely to be deposited externally or mternally. The vas

deferens of each species has been described earlier, J. lalandei (Fielder, 1964)

and P, pencillatus (Matthews, 1951). The glands of the proximal vas deferens

at P, pencillatus secrete a crystalline material, which surrounds the sperm-mass.

This walled sperm-mass continues into the large distal portion of the vas deferens.

Here it becomes convoluted and embedded in a matrix secreted by a large glan-

dular “typhlosole”. Sections through the distal vas deferens show sperm concen-

trated into # strand contained within the granular spermatophoric wall, the whole

embedded ina non-cellular matrix.

The proximal vas deferens of J. lalandei does nut secrete a granular swall

ivound the sperm-mass, but appears to initiate secretion of a Huid matrix, A

distinet strand pf sperm is therefore not formed. The resultant spermatophore

appearing im the distal yas deferens consists of clumps of sperm embedded in

the fluid matrix, A very thin crystalline wall appears tu surround the matrix,

Matthews (1951) described the spermatophoric mass of P. pencillatus as

being putty-like on extrusion. At a similar stage the aneimatophorie mass af

J. lalandei is a sticky, jelly-like mass, which remains discreet in sea-water. It is

reasonably fluid and could possibly be introduced into the oviduct. Absence ol

a erystalline wall around the sperm-mass would allew release of sperm on disin-

tegration of the mattix. Such disintegration of the matrix in the oviduct would

allow sperm to be stored between the yilli in the aviduct until needed,

lt appeers on morphological grounds then, that Von Bonde’s assumption

was correct and that fertilization in J. /alandei is internal. Observations of

captive animals also indicated that moultiny uf the female is a prerequisite far

mating. Four females moulted between Angust and October. Although males

Were present, mating was never observed, In each case, however. the female

died within two weeks of moulting without appreciable hardening of the exe-

skeleton. Post-mortem examination showed that the ovaries were ripe, No

sperm were detected in the oviduct or in the ovary. No external spermatophore

had been deposited, It must therefore be assumed that mating had not occurred,

166 D. RB. FIELDER

The fact that the four animals died without spawning may indicate that mating

is a necessary stimulus for spawning and failure to spawn may prove fatal.

Lindberg (1955) states that: “It is not known whether eggs will be extruded

in the absence of a sperm case, or without mating activity, but it is perhaps

significant that only fertilized eggs attach to the swimmerets. The presence, in

females not bearing sperm cases, of ripe ovaries late in the breeding season

may indicate, in fact, that egg extrusion does not occur in the absence of mating.”

DISCUSSION

In the absence of critical observation of mating and extrusion of eggs, three

factors appear necessary for successful spawning. These are (1) moulting pre-

cedes mating, (2) spermatophores are introduced in the oviducts where fer-

tilization occurs, (3) mating is probably a prerequisite of spawning.

It is unlikely that both genital apertures of the male and female would

often coincide durmg mating. It is also unlikely that egys are extruded from

one genital aperture only. If fertilization does occur in the oviduct, sperm must

be present in both oviducts if fertilization is to be complete. Further work is

required to determine whether a male is able to control extrusion of spermato-

phores or whether some sperm is lost by release from both apertures when one

does not coincide with a female aperture.

T. INTRODUCTION

Oxalis pes-caproe L., syn, O. cernta Thunb.2 is a serious bulbous weed

over thousands of acres in the agricultural areas of South Australia. It is a strong

competitor in crops and pastures and a well-known poisonous plant, oxalic acid

poisoning in sheep feeding on soursub (Q. pes-caprae) being first recorded by

Bull (1929). It is abundant also in home gardens, vineyards and orchards.

Although it oceurs in all Australian States, paddock-size infestations are

uncommon, except in South Australia. The most important infestations, outside

South Australia, are in the vineyard and orchard areas of Western Australia

and in part of the cereal belt of Victoria.

O. pes-caprae occurs as a weed in many other parts of the world, most

notably throughout the western coastal regions of the Mediterranean and in the

Cape Province of South Africa. Its overall Mediterranean distribution is men-

tioned by Rikli (1946) and particular references to it as a weed are given by

Hildebrand (1884) for Sicily, Morris (1895) for the Canary Islands, Ducellier

(1914) and Chevalier (1940) for Algeria, Knoche (1922) for the Balearic Islands,

Borg (1927) for Malta and neighbonring islands. and by Chabrolin (1934) for

Tunisia. Hildebrand (1884) first drew attention to its potentiality as a weed.

It seems certain that O. pes-caprae is a native of South Africa (Salter, 1944).

Thunberg (1781) noted that it was abundant at the Cape, both in and outside

gardens. Later published records in South Afriea are uncommon, however, and

do not give a satisfactory picture of its significance as a weed, Its major status

as a weed in the Cape Province of South Africa was noted by Hughes.*

II], VARIATION WITHIN THE SPECIES

_ Salter (1944) has described O. pes-caprae as a variable species in South

Africa, Similarly in Australia, different combinations of a number of characters

of both flowers and leaflets make for considerable variation. The more important

of these characters are:

(i) Sepals — presence or absence of purple markings on upper and/or

lower portion; presence or absence of orange or purple apical calli.

(ii) Petals — varying size; varying shades of yellow; reddish or whitish

tinge on underside; presence or absence of red mark on distal edge,

(iii) Leaflets — acute or obtuse angle at base; presence or absence of purple

markings as flecks, basal crescent and/or line (Fig. 1); reddish or pale

green apical mark; reddish or green pctiolules,

Double-flowered varieties have long been known in South Africa (Marloth,

1908) and in the Mediterranean regions ( Viviani, 1824, Ball, 1878; Morris, 1895;

Rappa, 1911; Borg, 1927; Chevalier, 1940), but are rare in Australia.

The flowers of O. pes-capraé are tristylic. They are described as short, mid-

and. long-styled according to the position of the stigma, whether it is below,

between or above the two: levels of anthers, respectively (Fig. 2), Fruitful

crossing is possible only between plants of different style length (Hildebrand,

1887; Sulter, 1944).

Infestations in South Austrulia und eastern Australia are primarily of a

single apparently stable variety, other varieties being uncommon. In Western

Australia clonal infestations of a number of varieties including that widespread

in South and eastern Australia are quite common. In South Africa variation

within the species is more striking although isolated colonies of one variety are

reported (Salter, 1944). The principal Australian variety is quite uncommon

in South Africa but appears similar to the common Mediterranean form as de-

OXALIS PES-CAPRAE IN AUSTRALIA 169

scribed by Viviani (1824), Willkomm and Lange (1880), Hildebrand (1884),

Nenslow (1891), Rappa (1911) and Borg (1927).

The widespread Australian and Mediterranean weed is a short-styled variety

with large bright sulphur-yellow flowers and orange apical calli on its sepals.

Its leatlets are Hecked with purple, offen with a poorly defined basal purplish

crescent. An excellent reproduction of this variety is presented by Loddiges

(1826b). It has been shown to be pentaploid (5y=35) by Vignoli (1937) for

Mediterranean matcrial, by Oram (1956) for Sonth Australian material, and by

Franklin (pers, comm., 1962) for material collected in Western Australia by the

author and in the immediate neighbourhood of Cape Town by Hughes. As far as

is known, the pentaploid variety exists in only the short-styled form.

Other varieties, however, have been shown to be tetraploid (4y,=28) b

Marks (1956) for South African matcrial supplied by Sulter and by Oram (1956)

and others at the Genetics Department, University of AdeJaide, for South Aus-

tralian material. These tetraploid varieties freely produce seed provided that

different style-length forms ure present.

In Australia, natural hybridization hetween the pentaploid clone and tetra-

ploid varieties of different style length is uncommon. At Albany, Western Aus-

tralia, in a mixed population of the pentaploid variety and a tctraploid varietv

with highly coloured sepals and small reddishtinged flowers, « few plants with

obviously intermediate characters were found, Leaflets of both the supposed

parent varieties and intermediates are shown in Fig. |, Phenotypic intermediates

have also been observed at Roseworthy Agricultural College, South Australia,

In Australia, leaflets Becked with purple are quite uncommon in varicties

other than the pentaploid clone. This flecked character, which is retained in

drying is of great value in the identification of this clone, both in the field and in

herbarium specimens. But, where mixtures of varieties occur, identification of

short-styled plants with Hecked leaflets must be made with caution until cyto-

logica] confirmation is possible or comparative pollen measurements can be made.

The mean size of pollen grains taken from anthers bore on the longer fila-

ments of the pentaploid variety is appreciably greater than that of grains taken

from anthers borne on the longer filaments of short- and mid-styled forms of the

tetraploid varieties. A comparison between pollen size of South Afriean and Aus-

tralian pentaploid materia) on the ene Iatud and tetraploid material on the other

Il. HISTORY

(1) The Pertaploid Variety

One of the varliest references to O. pes-caprae in Australia (under the uame

of O. cernva) is in “Catalogue of Plants Cultivated in, and for Sale at the

Hackney Nursery, Adelaide, 1845” in “The Adelaide Observer” on the 3rd May.

1845, The Hackney Nursery was established about 1641 by John Bailey, whi

hud beew previously employed by Loddiges, nurserymen, at Hackney, London.

lt is most probable that the plants sold by Bailey were the forerunners of the

weed now widespread in South Australia. O. pes-coprac, under the name of

Q. cernua, was listed in the catalogue of the Adelaide Botanic Garden in 1859

(Franeis, 1859). Schomburgk (1879) first recorded it as a weed in gardens

and in wheat crops, Clarke (ee ina short aceount of the history of the

plant in South Australia, concluded that it probably escaped from cultivation

in the early eighteen sixties.

It is probable also that early miroductions of this clone to Western Australia

came at least partly through the medium of Loddiges. It is known that Jarues

Drummond, who arrived in Western Australia in 1829, corresponded with and

cullectedd Western Australian plants for them. On his old property, “Iawthoru-

den”, near Toodyay settled in 1839, the pentaploid variety af O. pes-caprae can

still be seen growing around old fruit-trees and ovnamentals and has spread

downstream to Toodyay where it is abundant. Helms (1597) recorded O. pes-

caprae under the name of O, cérine, as a weed in Western Australia, the earliest

specimen in the State Herbarium, Western Australia, being a variety which

appears to be the pentaploid clone collected by him in 1895,

Infestations in eastern Australia almost certainly originated from horticultural

material, O. pes-caprae, under the name of O, cernua, was included in the

catulogue of plants grown by Sir William Macarthur at Camden, New South

Wales, in 1843 (Anon., 1843), Macarthur’s list of Oxalis species beurs a string

resemblance to Loddiges’ collection as featured in “The Botanical Cabinet”

(Loddiges, 1818-1833). or as listed in their catalogues (for example, Loddiges.

1826a). It was also included in the catalogues of plants grown in the Sydney

Botauie. Garden in 1857 (Anon., 1857), in the Royal Society's Gardens in Hobart

in 1865 (Abbott, 1865) and in the Queensland Botanic Gardens in 1875 (FTI,

1873), Kawart (1007) recorded it as widely spread in Victoria. It must have

escaped from cultivation many years earlier, the earliest specimen in the National

Herbarium of Victorja being one which appears to be the pentaploid clone, a

garden escape, collected in 1885. Although the first Australian record of the

naturalization of Oxalis pes-caprae (O- cernua) given by Spicer (1878) is for

Tasmania, the weed is now quite insignificant in that State.

Woolls (1880) recorded ©. pes-caprac, under the name of O. cernua, as

being naturalized around Sydacy. The pentaploid clone is now common encagh

in coastal towns of southeny New South Wales and in towns of the South-West

Slupes and the Riverina. It has rarely become a weed problem outside gardens

and cemeteries,

OXALIS PES-CAPRAE IN AUSTRALIA 171

Naturalization of the weed did not take place until much later in Queens-

land. It was not recorded by Bailey (1909) and, indeed, it is not common in

Queensland even now, Its present distribution is given by Everist (1959).

(ii) The Tetraploid Varieties

The earliest Australian specimen (in the National Herbarium of New South

Wales) of one of these varieties was collected in the Domain, Sydney, about

1902. A mid-styled variety from Western Australia is pictured in Carne and

Gardner (1927),

The history of these varictics, which are most prevalent in Western Australia,

is probably one of independent direct importation, both intentional, for orna-

mental purposes, and accidental, with vines, from South Africa. Clones of dif-

ferent varieties occur in neighbouring vineyards in the Swan Valley, near Perth,

and, for example, in the old settlements of Bunbury, New Norcia and Albany.

In Albany, the pentaploid clone is abundant also. Infestations at York in the

Avon Valley are of a variety quite distinct from the pentaploid clone present

in the neighbouring town of Northam.

Although, in general, these varieties occur clonally in Western Australia—

that is, only one style-length form is present—there are many areas in which

small populations of mixed varieties occur. Similar mixed populations occur in

172 P. W. MICHAEL

South Australia and New South Wales. In such situations, where different

stylelength forms are present, seed is freely produced.

A mid-styled variety with highly coloured sepals and reddish-backed petals

has been found in small patches, here and there, throughout a large part of

Victoria. This distribution suggests either that it was sold as an ornamental,

or that it was 4 common contaminant of nursery stock, Indeed, the latter method

of spread of this and other species of Oxalis is quite prevalent today,

(Chippendale, 1960, 1961, 1963) which referred only to Central Australia, Col-

lections of plants have extended with greater emphasis on the northern areas

of the Northern Territory, and new records are being found. It is, as yet,

premature to compile a Check List for the whole of the Northern Territory, but

it seéms better to discuss all records for the Territory at one time.

ASPINTACEAE

Polystichwin proliferum (R.Br.) Presl. Reedy Rock Hole, George Gill

Range, D. W. Madden, May, 1962 (NT10572).

A new record for Central Australia. Tindale (1961) mentions this specics

as occurring “mainly at high altitudes ... in rain forests or wet sclerophyll

forests”. This present record emphasises the refugial nature of the George Gill

Range, and is further evidence of the wetter conditions in Pleistocene time,
