Read 4th June, 1908.

‘TOWARDS the end of last year I gave a preliminary description of Koonunga cursor,

a remarkable crustacean with primitive Malacostracan characters *, and briefly compared

it with apparently allied forms, such as Anaspides tasmanie, G. M. Thomson, and the

Euphausiacea and Mysidacea. I now offer a detailed description of its external anatomy

and further discuss its possible affinities. I have also been able to examine a larval

form, which is described below.

I desire at the outset to acknowledge my indebtedness to Dr. W. 'T. Calman, of the

British Museum, for his kindness in seeing this paper through the press.

The following short descriptions are those published in my paper, but with some slight

amendments, due to the opportunity afforded me by Mr. Geoffrey Smith, Fellow of

New College, Oxford, of seeing drawings of a new form, evidently also belonging to

the order Anaspidacea, which he discovered on a recent visit to ‘Tasmania.

Order ANASPIDACEA, Calman, 1904,

Body generally slender, integument thin. Carapace absent. Thoracic somites

distinct, or with the anterior one fused with the head. Abdomen of about equal length

to the cephalon and thorax combined, somites distinct. Eyes stalked or sessile.

NEW TYPE OF MALACOSTRACOUS CRUSTACEAN. "3

KOONUNGA CURSOR, Sayce.

Specific Description.

Anterior portion of the body of subcylindrical form, becoming gradually rather broader,

deeper, and cylindrical posteriorly. All the segments of the thorax and abdomen subequal.

Abdomen equal in length to the thorax, last segment not longer than the preceding one,

with one or two dorsal spines close to the attachment of the telson. Telson entire, slightly

broader than its length, of triangular form and rounded apex, margin fringed with two

or more series of stout spines. Uropod with peduncle extending to half the length of

the telson, its branches somewhat longer than the peduncle, inner one fringed along the

inner margin with upturned spines, and three longer ones at the apex pointing outwards ;

outer margin and apex fringed with very long feathered setze; outer branch fringed

with long feathered sete, and the outer margin also with a row of upturned spines.

Mandibles each with a broad cutting-plate, that of the left side curving outwards,

and the edge divided into six stout teeth; that of the right side also broad, curved in

the reverse direction, and the edge divided into five stout teeth; molar process similar

in each, forming a well-extended broad ridge clothed with short, stout setze, surrounding

a minute triturating surface with chitinoid papillee.

Maxillipeds rather stouter than the legs, extending directly forwards about as far as

the distal end of the peduncle of the upper antennze, the seventh joint (dactylus) minute,

stout, and bearing four claws on the rounded extremity. The seventh joint, also, of

each of the. other limbs minute, and bearing three long, stout claws, the middle one

rather longer than the other two, which are placed closely on each side of it and

quite similar to each other.

Colour.—General appearance marbled dark brown. Microscopically showing a yellowish

stratum, thickly dotted over with rounded areas composed of black granules.

Length —Largest specimen measured 9°5 mm.

Occurrence.—From freshwater reedy pools beside a tiny runnel ret the Mullum

Mullum Creek, Ringwood, near Melbourne.

Remarks.—It is remarkably active ; usual form of locomotion running, but can spring

forcibly forwards and also swim easily. It shuns strong light.

Detailed Description.

The largest specimen I have seen measured 9'5 mm. in length, and it differed

morphologically in no important degree from others of at least 7 mm. The following

description is made after examination of several specimens between these two sizes, some

of which were seen alive. Its nearest ally appears to be Anaspides tasmanie, G. M.

Thomson, and I have made comparisons with it from descriptions and drawings by

Thomson (Trans. Linn. Soe., Zool. (2) vi. 3) and Dr. W. T. Calman (Trans. Roy. Sgt

Edinburgh, xxxviii. pt. iv.).

In general appearance the colour is irregularly marbled dark brown on body and

appendages ; microscopically the dark areas are resolved into small irregular and roundish

patches, composed of dark brown and black granules, the intermediate stratum being

yellowish. Alcohol’specimens show scarcely any difference in colour.

4 MR. O. A. SAYCE ON A REMARKABLE

The body is very slender, fully eight times as long as broad, and of almost uniform

breadth throughout. Anteriorly it is slightly dorso-ventrally compressed and of

subeylindrical form, but the depth gradually increases posteriorly, so that the last few

segments are cylindrical. The integument is smooth, thin, and membranous, and

contains no lime salts. There is no development of pleura, and the epimera are incon-

spicuous. It is divided into fourteen distinct segments, comprised of cephalon, seven

thoracie and six abdominal ones, all but the cephalon being subequal. They are freely

articulated one to another and all with similar powers of flexion.

The cephalon (Pl. 1. figs. 1, 2, 3) is about equal in length to the following two segments

combined, and is freely articulated to the following segment. Looked at from above

the shape is subquadrate, with frontal margin above the attachment of the antennules,

forming a wide evenly triangular projection, the obtusely-angled apex curving slightly

downwards between the closely approximated antennules. On each side of the base of

this triangular area the margin is incised, so that a narrow lateral lobe is formed

between it and the inferior margin.

I have critically examined the position corresponding to that where Calman has

observed what he thought might possibly be ocelli in Anaspides, but cannot find the

slightest indication of any in the present species.

Viewed from the side the dorsal line is almost straight, curving slightly downwards

anteriorly and posteriorly, and slightly depressed in the middle. The lobe on each side

is about the width of the basal joint of the antenna, the attachment of which it overlies ;

its upper corner is right-angled and the frontal margin meets the inferior margin in an

even curve, thence it runs almost straight hindwards for half the length of the head;

from here a definite sulcus runs obliquely backwards for a short distance, then turns

straight upwards and merges in the dorsum, where no trace of it can be seen; this

sulcus commences immediately posterior to the insertion of the mandibles, and

corresponds to the apparently definite division which separates the head from the thorax

in Anaspides. Immediately posterior to this sulcus the inferior margin commences to

descend gradually to a depth equal to that of the following segment, then to curve upwards

to meet the posterior margin. There is no branchial cavity formed. I can find no

trace of any lateral sulcus nor indication of division running obliquely across in the

position corresponding to that on the first thoracic somite of Anaspides.

The eyes are situated on the dorsum, at the angles formed by the union of the frontal

margin and the lateral incisions, and quite close to the frontal edge. They are very

small, circular, and uniformly black.

Pereon or Mesosome.—The seven segments are each of equal width to one another,

but gradually increase a little in depth posteriorly, the back is evenly arched from side

to side, the inferior margins slightly excavated above the attachment of the appendages,

and there are no definite epimera.

In the female just in front of the last pair of legs there is a development of the

sternum to form a small pouch (spermatheca), which is described later when dealing

with the appendages.

The Pleon or Metasome is of similar length to the perzon, and its segments subequal,

NEW TYPE OF MALACOSTRACOUS CRUSTACEAN. 5

except the terminal one, which, although of equal length to the preceding, becomes

rapidly attenuated, the dorsum declining in a straight line to the base of the telson; the

posterior margin is slightly excavated above the attachment of the telson, and

immediately lateral to that appendage it is produced to form a small acute triangular

tooth, at the base of which, on the inner side, there are one or two stout spines, pointing

upwards; lateral to the tooth the margin declines obliquely forwards along the line of

articulation of the uropods, to meet the inferior margin in a right angle. The inferior

margins of this and the preceding segment are inclined obliquely in opposite

directions, which allows of deeper fiexion than the preceding segments. There is no

development of pleura.

In male specimens there is a remarkable unpaired appendage projecting from the

sternum in the mid axis, and closely associated with the sexual endopodites of the

second pair of pleopoda. This I believe to be a development of the sternum and [I will

describe it later when dealing with the appendages of the abdomen.

The antennules (figs. 5 & 7) are nearly half the length of the cephalon and body

combined: the peduncle is stoutly built and equal in length to the cephalon; it is

formed of three joints, the first is broad, and as long as the succeeding two combined,

and bearing but few sete. The auditory organ is situated in this joint with the

opening on ‘the upper surface, and its form appears to be quite similar to that of

Anaspides. Thesecond and third joints are narrower than the first, subequal to each

other, and the inner and outer margins tufted with sets, most of which are slightly

feathered. The outer flagellum is slender, about twice as long as the peduncle and with

about twenty (more or less according to the size of the individual) short articles. The

secondary or inner flagellum is about one-half the length of the primary one and has

about eight articles.

The antennules have the following modifications in the males (figs. 7 & 7@).

Arising from the distal extremity of the last peduncular joint, at the inner angle, there

_is a short broad linguiform lobe with the edge evenly rounded, and fringed with long

curving faintly feathered sete. This lobe partly shields a remarkable pedunculated

eye-like organ, which projects obliquely towards the mid axis and underlies the basal

part of the secondary flagellum; it arises from the distal inner angle of the first joint of

the primary flagellum, which is distinctly stouter than the succeeding ones.

In shape it is somewhat like an ordinary pedunculated eye, but there is no pigment ;

the rounded outer surface is studded with closely packed minute hyaline hollow cups,

each attached to the surface by a short stalk (fig. 7a). From a casual observation this

organ might easily be’mistaken for an eye, but on closer examination that idea cannot

be accepted. Iam disinclined to believe it is of sensory function, and think it more

likely to serve a mechanical action, such probably as clasping the female; the surface,

studded with its tiny hollow disks, would help in discharging this function. It,

however, requires more careful study by means of sections than I have so far been able

to give, and it may be a sense-organ. Anaspides possesses sexual modifications in the

males on the first seven articles of the inner flagellum, but of quite different form to

the above.

6 MR. O. A. SAYCE ON A REMARKABLE

Antenne (PI. 1. fig. 6)—The peduncle is slender compared with the peduncle of the

antennules, and the last peduncular joint but little stouter than the first articles of the

flagellum. The peduncle is formed of four joints, the first quite short and subquadrate,

the second about twice as long, the third as long as the first and second combined, and

the fourth rather more slender and a little shorter than the previous one. The

flagellum is long and slender, about twice the length of the peduncle and formed of

about 18 articles.

In Anaspides there is a definite scale arising from the second peduncular joint, but in

the present species there is not even a vestige of one; otherwise they are in close

agreement.

The anterior lip (fig. 8) is thick and fleshy, curving evenly downwards without any

transverse ridge (epistome), the margin broadly and evenly rounded, and the tip furred

with short seta.

The mandibles (figs. 10, 11, 11a) agree closely with those of Anaspides, except that

there is no clearly defined spine-row. ‘The body is stout and supplied with a three-

jointed palp, the cutting-plate long, broad, and strongly curved between its lateral edges

(the curve of one side opposing the other in opposite directions); its distal margin

declines but very slightly inwards, and is divided into numerous strong acute teeth (six

on the left and five on the right hand side), and the inner lateral margin descends almost

at a right angle to join the basal part of the molar expansion. The molar expansion

is well developed and rises abruptly to form a rounded cushion-like ridge, thickly clothed,

in part upon the summit, and for some distance surrounding it, with long spiniform

setee; the outer edge of the summit is raised a little to form a minute grinding-surface

studded with chitinoid papillee, hidden by the surrounding sete, Between the cutting-

plate and the molar expansion there is no sign of any secondary cutting-plate nor

definite spine-row, but the setose cushion-like area united to the chitinoid extremity

may possibly have originated from one (fig. 11 @).

The palp is three-jointed and directed forwards and inwards, so that the distal ends

almost meet in the mid axis, a little in front of the anterior lip. ‘The first joint is

short and free from sete; the second almost three times as long, with a row of about six

long feathered setve along the inferior margin of the distal half; the third is minute,

apically broadly rounded, and bearing several long feathered sete.

Posterior lip (fig. 9).—This is formed of two membranaceous, narrow, ovoidal, widely

divergent lobes, connected together at the base, and the inner edges of the lobes are

fringed with setee.

The first maxilla (fig. 12) consists of two lobes; the outer or distal one bears a minute ©

one-jointed palp on the outer face, pointing distally (not reflected backwards as in the

Cumacea), and tipped with three very long spinules, feathered along their inner margins;

the obliquely truncated summit of the lobe bears a double series of about ten strong

ycllow spines, not toothed, as in Anaspides, but faintly feathered, and the inner face

curves outwards to form a small rounded expansion. The proximal or inner lobe is

short and narrow, being only half the width of the outer lobe, and the summit bears

NEW TYPE OF MALACOSTRACOUS CRUSTACEAN. 7

one remarkably long stout feathered spine surrounded by four much smaller feathered

ones, otherwise the lobe is unclothed.

The outwardly turned lacinia (exopodite) which this segment possesses in Anaspides,

in common with the Euphausiacea and, to a less extent, the Mysidacea, is incon-

spicuous—if, indeed, it exists even in a rudimentary form. The corresponding part of

the segment in the present species appears to curve a very little outwards, but there are

no setz fringing it.

Compared with <Anaspides this appendage is more specialized, showing a. certain

resemblance to that of the Amphipoda. The outer lobe is quite similar to that of

Anaspides except for possessing a more definite palp; the inner lobe, however, is

not simply foliaceous, but more modified and there is no definite exopodite.

The second maxilla (P\. 2. figs. 13 & 18) is a little smaller than the first maxilla and

is formed of four foliaceous lobes: the innermost is very short and the others gradually

increase successively in length; the first or innermost is quite narrow, the extremity

occupied by one short and two longer straight feathered spinules; the second broader,

and apically bearing five feathered and plain slightly curved spinules and sete; the

third broader still, and bearing about ten spinules and sete of a similar kind. The

fourth lobe is divided by a faint line of articulation, and may be considered the palp ;

it is rather broader than any of the other lobes, and carries ten or more long spinules,

and a little below the summit on the outer side there is another single feathered one.

This appendage agrees essentially with that of Anaspides, but in that genus the

lobes are shorter and broader. In fig. 13 the lobes are flattened somewhat out of

normal shape to make the drawing clear.

‘The mazillipeds (figs. 8, 4, & 14) agree in their general form with the succeeding

limbs, but are distinctly stouter, and have no multiarticulate exopod, but instead a

small simple one of branchial function. hey are set close together at their origin, and

extend directly forwards, covering the buccal area, and reaching far past the head to

the limit of the peduncle of the upper antenne. They serve principally as legs and for

grasping purposes, and also to a very slight extent as foot-jaws. The three attached

lobes fulfil a respiratory function.

The first joint (coxa) is short and very broad, and attached to the ventral surface of

the cephalon ; both it and the succeeding two joints are flattened on the inner face so as

to embrace closely the buccal area; the outer face is strongly convex, and close to the

frontal edge there arise, close together (not wide apart as Calman has shown in

Anaspides), a pair of small, simple, narrowly ovoidal lamelle of branchial function,

which are transversely segmented near their proximal end, and between these and the

ventral surface of the cephalon, also on the outer side, there is a minute tubercle covered

with fine sete. The inner side is expanded, the edge quite straight and closely opposed

by its fellow of the other side; the distal margin is prolonged into a short triangular

extension beyond the union of the second joint, with its apex tipped with a few short

setze (fig. 4). Had this arisen from the second joint one might have felt justified in con-

sidering it a rudimentary masticatory plate, which becomes such a pronounced feature

8 MR. O. A. SAYCE ON A REMARKABLE

in the Amphipoda. It may, however, be merely a specific character without

morphological interest. These parts are best seen from the ventral aspect, with the

appendages in their natural position, as shown in fig. 4; when dissected out the

rather peculiar joining of the second joint to the first makes the parts difficult to

understand. here is no vestige of the gnatho-basic lobes which are found in

Anaspides.

The second joint is short, of subquadrate form, and from the frontal or upper

margin of the outer fave there is a linguiform lobe (the exopodite), which extends

forward to a little beyond the end of the third joint and is transversely divided near its

proximal end.

The third joint is subquadrate and clothed rather densely on the inner face with long

setae, most of which are faintly feathered. The fourth is about one-third longer than

the preceding one, swollen to a slightly ovate form and bearing a few long sete; the

fifth is quite short and its articulation with the preceding joint permits great flexion ;

the sixth is slightly longer but not narrower than the fifth; the seventh is minute,

appearing as a broad rounded tubercle, bearing on the apex a row of four stout curved

claws.

Compared with Anaspides there is one joint less in number, due to the complete

coalescence of two joints, which I think most likely to be the second and third; the

relative lengths of the third, fourth and fifth are very different, but the three terminal

ones are in agreement. As previously mentioned, the appendage does not possess any

gnatho-basic lobes.

Appendages of the Perwon or Mesosome.— All the legs have the corresponding joints

almost identical with each other, and, except for being more slender, also with those

of the maxillipeds. The first three pairs are of about equal length, the fourth

distinctly longer, the fifth and sixth subequal to the anterior three, and the seventh

rather longer but not so long as the fourth. The first six pairs have the joints articu-

lated, so that the claws point backwards, but the last pair are quite reversed, so that

they point forwards; this is brought about by the reversal of the flexion of the three

last joints. There appears to be no information concerning the arrangement of the legs

in Anaspides, and I am not aware of any crustacean being quite like Koonunga in this

respect, except some Decapods, e. g. Astacopsis serratus, and also Astacus fluviatilis

according to the drawing in Howes’s biological atlas. However, this character is not a

reliable one for a natural classification, in proof of which it may be pointed out that

most of the Amphipoda and some Isopoda of widely different genera agree in having the

anterior four legs bending backwards, and the remaining three forming another series

bending in the reverse direction. This reversal, however, takes place at the articu-

lation with the body, but that does not affect the question as to the reliability for a

means of classification. Each pair will now be considered in detail.

The first appendage of the pereon (corresponding to the second thoracic of Anaspides)

(figs. 38, 4, & 15) is of similar form to the maxillipeds, but more slender ; the first joint,

together with the branchial lobes, is quite similar, except that the lobes are larger,

NEW TYPE OF MALACOSTRACOUS CRUSTACEAN. 9

although not so large as in Anaspides. It is united to the body-seyment without any

coxal plate or line of division. The second joint compared with Anaspides is formed

by the complete coalescence of two joints; it is stout at the base, but narrows

considerably beyond the origin of a large and strongly developed swimming-exopod, the

peduncular joint of which is stout and carries a flagellum of about seven articles, each

bearing two long curved feathered setze. The third joint, corresponding to the fourth in

Anaspides, is narrower than the preceding one and of subquadrate form; the fourth of

equal length to the second and third combined ; the fifth is short, and it is apparent that

the articulation between the fourth and fifth is more flexile than any of the others; the

sixth joint is nearly as long as the fourth, but narrower; the seventh minute, and bearing

a row of three (not four as in the maxillipeds) closely-set stout claws, the middle one

being distinctly longer than the other two, which are equal to one another. All the

joints except the first are sparsely tufted with long sete, some of which are faintly

feathered.

The second, third, and fourth are so much like the first pair that nothing further need

be said of them, except that the fourth has the three last joints distinctly longer than the

preceding appendages.

The jifth agrees closely with the preceding legs, but is not so long as the fourth. In

the female, in addition, there projects from the inner margin of the coxa a small lamellar

jobe fringed distally with incurved setée (fig. 16), close beside which is the opening of the

oviduct. The clothing is much like that of the preceding limb, and in addition there

js, on the distal inner margin of the fifth joint, a transverse row of five or more long

acute spinules, pectinated on each side for half their length, thence finely setose to the

apex (Pl. 2. figs. 17 & 17a).

The sixth agrees in all respects with the fifth but has no exopodite, and the branchie

are smaller; the female also possesses a similar setose lamella on the inner side of the

coxa.

The seventh is longer than the preceding limb and without any branchial lobes or

exopodite, neither are there any setose coxal lobes in the female. In other respects they

are alike. In the males the opening of the vas deferens is on the inner side of the first

joint. The female has a peculiar development arising from the sternum, in the median

region and a little in front of the legs; it consists of two small closely approximated

ovoidal lamellee, widely attached at the base, and just behind these there is another

minute one, and the three together form a little pocket or pouch, which is likely to be a

receptacle for the spermatophore (spermatheca),

In comparison with Anaspides the appendages of the person agree pretty closely,

except that in the present species the branchiz are smaller, the peduncular joint

of the endopodites stouter, and also the second joint represents the second and third

of Anaspides completely coalesced.

Calman says in respect of this that in Anaspides the second joint is ‘‘ very small, and

partly fused with the third joint, from which, however, it is marked off by a distinct

line. ...” and “ becomes less distinct as we go backwards, while in the sixth pair the

fusion of these two joints is complete, and the exopod appears to spring from the ischium ”

(third joint). In Koonunga, therefore, the legs are chiefly flexed at the articulation

between the fourth and fifth joints, as is the case in the Euphausiacea and Decapoda,

instead of the fifth and sixth joints, as shown by Calman to occur in Anaspides.

The relative length of the several joints is seen to be in close agreement in the two

species by reckoning the second and third together in Anaspides as equalling the second in

Koonunga. It will be seen, therefore, that this does not mean any more than that what

is partly coalescent in one species is completely so in another. Dr. Hansen has adduced

reasons for using this character as a basis for classification, but it is certainly not reliable

in the present order, and I venture to think that Dr. Calman’s * definitions of his divisional

groups would be better without its inclusion, for it is not always easy to correlate the

several joints by numbers from the base.

Abdominal Appendages (Pleopoda).—In the female the first five pairs are quite similar

to each other, except that they successively become a little shorter. They are used for

the purpose of swimming, and each consists of a short stout basal joint followed by a

longer one; then follows a long multiarticulate flagellum with each jomt bearing two

long feathered setze. Thereis no vestige of a secondary branch (endopodite) as in Anaspides.

In the males the third, fourth and fifth are quite like those of the females, but the first

two pairs possess endopodites modified for sexual purposes (figs. 18, 19, & 20). The form

of these endopodites is almost identical with that observed in Anaspides. The first pair

is short and broadly spatulate, with the distal margin deeply incised, and the inner

margin distally bearing some coupling-spines (figs. 18 & 19). It lies underneath the body,

and is directed forwards between the last pair of thoracic limbs, with its deeply concave

surface uppermost, and when united by the coupling-spines to its fellow of the opposite

side it forms an efficient pouch, which, probably, serves the purpose of a receptacle for

holding the spermatophore after passing from the vas deferens, the opening of which is

on the first joint of the last pair of legs and thus quite close to it. The endopodite of

the second pair is exactly like that of Anaspides (figs. 18 & 20) and forms a long two-

jointed styliform appendage ; the first joint with a row of coupling-spines, and the second

joint apically pointed, and hollowed out on its distal inner face to form a deep concave

area, Which, together with that of the opposite side, forms a little pocket, and when

lying horizontally is located within the anterior spermatophore carrier. Each is articu-

lated, so that together they have power of movement downwards. By these organs a

spermatophore may easily be passed from the vas deferens to the receptacle formed by

the union of the first endopodites ; from this it can be received in the pocket formed by

the union of the second pair of endopodites, and from this it can easily be transferred to

the receptacle in the female, which is medianly situated on the sternum in front of the

last pair of legs, and behind the openings of the oviducts on the inner side of the first

joint of the filth pair of appendages of the pereon. How the ova are fertilized is not

clear, nor is it known if the spermatozoa are filamentous or not.

Immediately behind the second appendages there is a peculiar median appendage

arising from the sternum, which, in ventral view (fig. 20), is of sagittal form, the apex

NEW TYPE OF MALACOSTRACOUS CRUSTACEAN. jh

pointing backwards, and the base closely occupying the area between the pair of endo-

podites. Viewed from the side (fig. 18) the apical portion is seen to curve downwards.

Probably the purpose of this process is to aid in holding the female during copulation.

Uropoda (PI. 2. fig. 21).—These have, relatively to Anaspides, a longer basal part, and

the two branches (endopodite and exopodite) are slightly narrower and without any

keel or transverse suture. The peduncle is stout and projects halfway to the end

of the telson, with a few spines on the upper surface; the branches are subequal, of

lanceolate shape, and not much longer than the peduncle, the inner one fringed

along the inner margin with strong spines and three longer ones distally, and the

outer margin fringed with very long feathered sete; the outer branch fringed

throughout with long feathered sete, and the outer margin in addition fringed with

spines.

The telson (fig. 21) is short, broad, and of triangular shape, with the apex broadly

rounded ; the dorsal surface is convex and the margin fringed with two or more

series of stout spines. Compared with Anaspides it is very much shorter.

Description of a Larval Form.

I have been able to examine one specimen of a larval form (figs. 22-25). If measures

2°5 mm. in length and its general appearance is like that of an adult. All the

appendages of the head and perzeon are well developed, and so also are the terminal

pair of the abdomen, but the five preceding pairs are rudimentary. I offer some

details concerning it.

The cephalon has the first thoracic somite joined to it without any distinct mark

of division more than a lateral sulcus as in the adult. The front, in dorsal view, is

broadly and evenly rounded with the margin entire, the eyes small and situated on

the dorsum, and the body-somites all clearly marked off and quite similar in form

to the adult.

The antennules have no difference from those of the adult, except that the joints of

the flagella are relatively stouter, longer, and much fewer in number. This is also

the case in the antenne (fig. 24), so that there is no apparent difference between the

peduncle and flagellum.

None of the appendages of the buccal area showed any structural differences, and

although I suspected that I might be able to determine a spine-row in the mandibles,

I failed to do so.

The first appendage of the perzon is quite similar to that of the adult, except in

having fewer articles in the flagellum of the exopod. The three claws of the dactylus

are fully matured. The second and third pairs offer no important differences from the

preceding one. The fourth (fig. 25) is also in agreement, except that the dactylus

has but one very long claw, and a seta on each side of it, instead of three claws

(fig. 25a). This seems to show that the two lateral claws which exist in the adult,

and also in the preceding limbs of this larva, are modified sete; and this gives some

support to Dr. Hansen’s view that the terminal claw of the Malacostracan limb

represents a separate joint. However, I only know of Hansen’s generalization through

12 MR. O. A. SAYCE ON A REMARKABLE

Dr. Calman (Ann. & Mag. Nat. Hist. (7) xiii. p. 152), and I emphasise the facts for

others to accept for what they are worth.

The fifth, sixth and seventh appendages of the perwon are in close agreement

with the fourth. The appendages of the pleon (fig. 23) are, with the exception of the

terminal ones (uropoda), quite inconspicuous and functionless, appearing only as

minute one-jointed papille on each somite. The uropoda and telson are, however,

quite similar to those of the adult form.

Habitat.—The only locality where Koonunga so far has been found is a small extent

of shallow marshy country through which a tiny rivulet flows, at Ringwood, near

Melbourne. The water is almost entirely dried up for a few months each summer,

and indeed is entirely so during some years of less rainfall. The elevation is but

slightly above sea-level.

The little crustaceans inhabit the small weedy pools and they are remarkably

active; their usual form of locomotion is running, but they can swim rapidly. On

one occasion I saw one swimming on its back, just as some Phyllopoda do, but this

is quite exceptional. On most of those examined there were a number of sedentary

Rotifera of the genus Floscularia, and these were lodged principally on the branchie.

Systematic Position of Koonunga.

The foregoing description will have amply demonstrated the relationship of the

sessile-eyed Koonunga to the stalk-eyed Anaspides, and warrants my placing them

together in the same order; and also, I think, proves my previous statement to be

justified, that it is the most primitive Edriophthalmatan so far known.

The following synopsis of characters of these two forms may help to focus the mind

upon their features of agreement and disagreement :—

It is obvious from a review of these two forms that Koonunga, more particularly, shows

conspicuous modifications in the direction of the sessile-eyed characters, notably in the

coalescence of the first thoracic segment and head, the character of the eyes, the mouth-

parts, and also in the absence of any antennal scale.

I was hopeful that Koonunga wouid have shed considerable light on the Cumacea and

Tanaidacea, but after careful examination I fail to find any of importance. The divergent

sessile-eyed branch of the stalk-eyed stem seems to have a wide gap between Koonunga

and other forms. It may be mentioned, however, that in Koonunga there isa good deal

that points to the Amphipod type, at least, more than to the Isopod, notably in the general

form of the body and its somites, the position of the eyes, which are above the base of the

antennze, not lateral to them, as in the Isopoda, the shape of the first maxille, the pleopoda,

and also in the short terminal somite and its uropoda, together with the telson; but there

are very many characters of dissimilarity to that order, as well as to the other sessile-eyed

forms; of these the following characters may be mentioned: the absence of a brood-

pouch, the antennal peduncle having four instead of five joints, the absence of a secondary

cutting-plate (lacinia mobilis) in the mandibles, and the possession of an auditory organ

at the base of the upper antenne.

Undoubtedly there is a much closer relationship with the stalk-eyed forms, and of these

it is nearest to the Mysidacea and Euphausiacea, but, although there are many characters of

agreement, there are such marked and apparently dominant characters of difference that

I believe it better placed in a separate order from either of them. Of the two, Koonunga

is nearest to the Euphausiacea, at least in its external anatomy, notably in the uniformity

of the maxillipeds and thoracic limbs, the mandibles not having a spine-row, the pleopoda,

with their sexual differentiation, and the absence of a brood-pouch. One would have

expected that it would have been in closer relationship to the Mysidacea, but, judging

from its outward appearance alone, this is not so.

14 MR. O. A. SAYCE ON A REMARKABLE

From these two groups the following fundamental external differences occur :—A bsence

of a carapace, presence of a double series of leaf-like epipodiat branchize on the thoracic

limbs, which are seven-jointed and well adapted for walking, also the presence of an

auditory organ in the base of the upper antennze. In all of these Anaspides also agrees.

It must be acknowledged that until more is known of the internal anatomy and

embryology of the Anaspidacea the systematic position is rather uncertain. I understand

from Mr. Geoffrey Smith that he will shortly make a further contribution to our

knowledge of the anatomy of Anaspides, and, if opportunity permits, I hope to do some-

thing for Koonunga during this year. Iam alive to the importance of a knowledge of

its embryology, and will do my best to procure material for this also.

In respect to other forms that bear a rather close resemblance in some important

characters to the present species, I may refer the reader to Dr. Calman’s paper in the

Journal Linn. Soc., Zoology, xxvii. (1899) pp. 338-344, on Bathynella natans, Vejdovsky,

a minute crustacean taken from a well in the city of Prague, and also to his remarks

concerning some forms from the Paleeozoic Coal-Measures (Trans. Roy. Soc. Edinburgh,

xxxviii. (1897) pp. 796-801). Restored drawings are there given, with valuable remarks

on the comparison with Anaspides,

Note on some Characters of Koonunga and Anaspides.

By W.T. Caiman, D.Se., F.L.S.

In presenting to the Society Mr. Sayce’s account of his very remarkable discovery,

I take advantage of his kind permission to add a few observations.

In the original account of Anaspides, the positions of the genital apertures were

wrongly given. Anaspides agrees with Koonunga and with all other Malacostraca in

having the openings in the female on the sixth and in the male on the eighth thoracic

somite. The oviducts open on the inner face of the coxopodites of the sixth pair of

thoracic appendages. Just distal to the aperture, the coxopodite bears a setose lobe,

turned forwards, and similar lobes are present on the coxopodites of the fifth and seventh

pairs. The male ducts open, not on the coxopodites, but on the sternum of the last

thoracic somite, by oblique slits converging anteriorly. The terminal part of the vas

deferens is enlarged and apparently glandular.

On the sternum of the last thoracic somite in the female is a curious structure repre-

senting the spermatheca which Mr. Sayce has discovered in Koonunga. It is a rounded

prominence, directed forwards, with a wide transverse slit at the tip. This aperture

(erroneously described as the opening of the oviducts) gives entrance to a blind sae with

thick walls, on each side of which at the base is what appears to be a racemose gland

opening into its cavity by a short duct.

It seems to me a significant fact that the only structures (so far as I know) comparable

to this spermatheca are found among the Decapoda, with which, it may be recalled, the

Syncarida also share the possession of an antennal statocyst. In the Penzide the structure

described by Spence Bate as the “ Thelycum,” situated on the thoracic sternum between

16 ON A NEW TYPE OF MALACOSTRACOUS CRUSTACEAN.

the bases of the last two pairs of legs, is now known to be a sperm-receptacle *. In the

Lobster (Homarus) a sperm-receptacle in the same position has been described by

Bumpus ft, and in the Crayfishes of the genus Cambarus a similar structure is known as

the “annulus ventralis.” Andrews ¢ does not consider the structures in the Lobster and

Crayfish to be homologous, and does not refer to that of the Penzeidee. It seems probable,

however, that a comparative investigation of the three types of organ in the Decapoda

together with that of the Syncarida might yield results of interest.

The most striking and unexpected character of Koonunga is the sessile condition of the

eyes, which makes still more plain the impossibility of continuing to regard the two

genera as “Schizopoda.” I see no reason to modify the opinion which I formerly

expressed §, that Anaspides must be regarded as representing a distinct Order, forming

by itself a Division of the Eumalacostraca, to which Packard’s name Syncarida has been

given. To this Order Koonunga must now be added, and I do not think that the

modifications thereby rendered necessary in the definition of the group in any way impair

its distinctness from the other Divisions of the Malacostraca.

PREFATORY NOTE.

Tue following paper by Miss R. M. Harrison is the partial fulfilment of a piece of

work undertaken by me some years since and long overdue. It is necessary that IL

should give an explanation of the circumstances under which the first collection of

Aleyonaria made by the Trustees of the Calcutta Museum came into my hands, and

why the publication of this work has been so long delayed. The Aleyonaria were sent

in the first instance to Mr. W. L. Sclater for identification and description : on his

leaving Eton College for 8. Africa he found himself unable to complete his preliminary

investigation of the material, and after asking several other authorities to undertake the

_ work, he eventually entrusted it to me, with the consent of the Trustees. By 1899 I

yy had made some progress in working out the Spongodide and Siphonogorgiide, but on

_ the outbreak of the war in S. Africa I was called away on military duties and the work

_ was | laid aside. Since then the pressure of other work has prevented my resuming it,

and i in 19071 gave the collection together with my notes and drawings to Miss Harrison,

“i asked her to begin the investigation afresh. This she has done in a very able

er. But I was not aware, for I had not been informed, that meanwhile the

Desens of the Caleutta Museum had officially entrusted the description of the collections

Alcyonaria made by them in the Bay of Bengal to Professor J. Arthur Thomson, and

he was equally unaware that the earliest collection was in my possession. Consequently

there has been a certain amount of overlapping in the work done under his direction and

mine on collections of Aleyonaria from the same area. My apologies are due and are

hereby tendered to the Trustees of the Calcutta Museum and to Professor Thomson

for the long delay, which has possibly introduced a confusion in the naming of certain

species. At the same time I have to thank Professor Thomson for prompt and kind

co-operation, which I hope will minimize any confusion that may possibly arise.

It will be observed, however, that one of the five new species of Spongodes and seven

of the eight new species of Ohironephthya described by Miss Harrison do not come from

the Indian Ocean, and do not form part of the collections of the Trustees of the Caleutta

Museum.—G. C. Bourne.

18 MISS RUTH M. HARRISON ON NEW ALCYONARIA

I.—INTRODUCTION.

‘THE forms dealt with in this paper come from three sources. The greater number of

Siphonogorgiidee (Stphonogorgia and Chironephthya) were collected by Capt. Bassett-

Smith, R.N., of H.M.S. ‘ Egeria,’ in the Admiralty Islands, and presented by him to the

3ritish Museum. A single and interesting species of Spongodes was collected by Capt.

Chimmo in the China Seas and presented to the Oxford Museum. ‘The remainder of

the species described form a part of the first collections made in the Bay of Bengal by

the Trustees of the Calcutta Museum, and eventually entrusted to Professor G. C. Bourne.

I am glad to have this opportunity of expressing my thanks to Professor Bourne for

providing me with this material and also for placing at my disposal all the resources of

his laboratory, but more especially for his invaluable help and kindness during the

progress of my work. My thanks are also due to Professor F. Jeffrey Bell for allowing

me to examine the Spongodes and Siphonogorgiidx in the British Museum (a descrip-

tion of some new Siphonogorgiidze will be found in the following report) ; to Professor

J. Arthur Thomson, of Aberdeen University, for the loan of two of his Spongodes ; and to

Dr. E. H. J. Schuster, Fellow of New College, Oxford, for the beautiful photographs on

Plate 3.

The paper is confined to five species of Spongodes, all of which are new, two Siphono-

gorgia, of which one is new, ten Chironephthya, of which nine are new, and four

Solenocaulon.

The difficulties in the identification of these forms have been very great, owing partly

to the fact that sech numbers of new species have been created, frequently based on only

a single character, and partly because many of the descriptions and figures are quite

inadequate, and the same characters are seldom consistently described in the different

species. Sometimes stress is laid on the shape of a colony or the mode of branching ;

sometimes on the spicules of the stem or branches, special attention being paid to their

size, their character, or their arrangement; or the armature of the polyp or the tentacles

may have been considered of primary importance.

Kikenthal (30) has revised the classification of the genus Spongodes, and he bases his

main divisions on the mode of branching of the colony and the grouping of the polyps

on the terminal branches. He recognizes three types :—(1) Glomerate : branching

slight; polyp-bundles in smaller or larger rounded groups, surface of polyp-bearing part

consequently much broken up. (2) Divaricatze : branches much spread out and diverging

from one another; polyps scattered on slender terminal twigs and not gathered together

in bundles. (8) Umbellatee: terminal twigs form umbels, with polyps borne on the

surface of the polyp-bearing portion, and never on stem or main branches. He makes

further subdivisions, using such characters as the predominance of the stem and main

branches over the polyp-bearing twigs in the development of the colony or vice versa ;

the regular or irregular outline of the polyp-bearing part ; the plane in which the polyp-

bearing part develops, or its shape.

Having had an opportunity of inspecting the British Museum specimens, and judging

{rom the five species described below and the beautiful photographs which illustrate the

FROM THE INDIAN AND PACIFIC OCEANS. 1g

p2pers of Kiikenthal (30), Holm (20), and Burchardt (5), I feel convinced the foundation

on which Kiikenthal has built his three main divisions touches a question of primary

importance. Just as an oak or an elm or a beech stripped of its leaves shows a totally

different mode of branching, so, I believe, the way in which the polyps are grouped on

the terminal twigs, the mode of aggregation of the twigs to the branches, of the branches

to the stem are characters of subgeneric value. On the further details of shape I feel

less stress should be laid, for I am of Professor Hickson’s opinion that the exact form

and mode of branching of a colony is influenced to a large extent by the external con-

ditions. Since that is a subject on which we can get no positive information, it seems to

me safer to neglect details of form and shape and to confine the specific diagnosis to

the mode of aggregation of the twigs and branches. For example, while I consider the

difference in the form of growth between Spongodes thomsoni and Spongodes chimmii

sufficient to be of subgeneric importance, such distinctions as to whether the polyp-

bearing surface is a long oval or a broad oval or practically spherical are highly

unsatisfactory. Jam unable to add anything as regards the anatomical and histological

characters, owing to the poor state of preservation of my material. But I believe that a

reliable character on which to base specific groups is to be found in the spiculation.

The sterile stem bears spicules totally different in character from those of the branches,

and the spicules of the inner partition-walls are different again from those of the outer

wall. The armature of the polyp-heads of a colony shows a general agreement in the

arrangement of the spicules, although there may be a considerable amount of variation

in the individual polyps. The variation between the polyps of different colonies is often

very striking, as is obvious from a comparison of such forms as S. argentea, S. clavata,

S. hicksoni, or S. kéllikeri, all examples of the division Glomerate. These variations

are accompanied by differences in other characters. Taking the spicules of the partition-

walls: argentea has broad warty spindles 1:2 0°3 mm. in size; clavata has merely little

rods 0:06 mm. long; hicksoni and kéllikeri both have spindles much the same size,

2:0X035 mm. and 2:°0x0:2 mm. being the given measurements, but those of hieksoni

are mentioned as being hooked and curved. In the branch-walls argentea has slender

thorny spindles; clavata has two kinds—spindles 2°6 mm. long, and numerous small

thorny spindles 0°2 to 1:2 mm. in length; in both hicksoni and kéllikeri the spicules

are set transversely, but the difference in size is 2°8x0°22 mm. and 6:00:19 mm.

respectively. These examples leave little room for doubting that the four species are

quite distinct and are rightly separated. It is when such characters as these are not

consistently different or consistently similar that the task of species-making becomes so

difficult. An added difficulty is the variation between different described specimens of

the same species. For example, in the British Museum there are two specimens labelled

S. divaricata, in one of which the body of the polyp is unarmed, the tentacles

only bearing spicules; in the other each point has one large projecting spicule and two

or three smaller ones inclining towards it; in neither case do they answer to Kikenthal’s

description of a polyp armed with ‘‘ Doppelreihen von je funf spitz konvergierenden

Spiculapaaren.” Again, the one with no spicules in the polyp has large spicules in both

the outer and inner walls, the other has small spicules in the outer walls and none at all

20 MISS RUTH M. HARRISON ON NEW ALCYONARIA

in the canal-walls; in neither could I find spicules resembling those figured by

Kikenthal. Itis difficult to see on what grounds these specimens have been considered

the same species, and Gray’s original diagnosis is so sketchy that it is not possible to

determine which form has prior claim to the name 8. divaricata. On the other hand, it

is probable that there are many instances where new species have been made on

insufficient grounds. With this in view, Kiikenthal has considerably reduced the

number of described species. For example, the two ‘Challenger’ specimens named by

Wright and Studer §. cervicornis and S. rhodosticta respectively, he regards as one and

the same species, on the grounds of great similarity in the general plan of growth and in

the armature of the polyp. They also agree in the absence of spicules from the canal-

walls, although this seems to have escaped his notice. There is, however, a striking

difference apparent even to the naked eye on which he scarcely lays sufficient stress; this

is the contrast between the spicules of the barren stem. In S. cervicornis they are long

spindles disposed more or less transversely ; in S. rhodosticta they are small, very

irregular, thorny, many-rayed structures. The polyp-heads are also different in colour,

being purple-red in one and orange-red in the other. If these differences are not

sufficient to outweigh the points of agreement and to justify a separation of the species

they are at least worthy of special mention. At all events, the above examples illustrate

soine of the difficulties to be contended with in the identification of species and show how

necessary are co-operation and comparison in a genus of such variability and magnitude.

The subfamily Siphonogorgiacee was made by Kolliker (25), who regarded it as

intermediate between the Alcyoniide and the Gorgoniidee, and in it put the single genus

Siphonogorgia. Wright and Studer (57) placed Stphonogorgia, together with Chiro-

nephthya, Paranephthya, and Scleronephthya, in the subfamily Siphonogorgiinee of the

family Nephthyide, distinct from the other subfamily Spongodinz in the abundant

presence of spicules in the canal-walls. Kiikenthal (27) removed the genera Pura-

nephthya and Scleronephthya to the new genus Paraspongodes in the family Nephthyidee,

and raised the subfamily Siphonogorginee to the rank of a family equal to the

Nephthyidz as the family Siphonogorgiidee, and in it he placed the genera Siphonogorgia

and Chironephthya—the justification for this step being that the Siphonogorgiide are

intermediate in form between the Nephthyidz and the Gorgoniide ; and he gives as

the diagnostic characters of the family: “Ein Stammteil fehlt. Kolonie aus wenig

verzweigten cylindrischen Asten bestehend, auf denen die in einen Kelch zuriickziehbaren

Polypen sitzen.” I do not know what is meant by ‘“ Ein Stammteil fehlt.”. In many

of the species there is an obvious stalk figured—for example, Siphonogorgia pendula or

Chironephthya dipsacea ; and it is so very easy for the stalk to become broken in the

process of dredging that it could hardly be a character of much value. In the present

report I follow Kikenthal in recognizing the family Siphonogorgiide, with the

following characters :—Erect tree-like colonies with stiff, slender, cylindrical branches.

Polyps may or may not be retractile. Canal-walls richly filled with spicules.

The family contains two genera, Siphonogorgia and Chironephthya.

The original diagnostic characters of the two genera have been shown by Prof. Hick-

son (18) to be inconstant, but I believe there is a really reliable distinction in the form

FROM THE INDIAN AND PACIFIC OCEANS. 21

of growth and the mode of branching of the canal-system. Siphonogorgia is a solid

massive growth in which both stem and branches are round and cylindrical, the whole

colony being of a rigid brittle consistency. Chironephthya may or may not have a round

cylindrical stem, but the branches lose the solid appearance and become somewhat flattened

and deeply grooved, and the terminal twigs are very much more slender than those of

Siphonogorgia. ‘Turning now toa section, the reason for this becomes obvious. In the

barren stem of Stphonogorgia (text-fig. 1) there is one large central canal and numerous

Fig. 1.—Transverse section through the barren stem of Siphonogorgia rotunda. In this and the succeeding text-

figures the mesogl@a is represented in black; the cavities occupied by the spicules before decalcification

are left white; the endoderm lining the central canal and solenia is represented conventionally.

Fig. 2.—A transverse section through the stem of Chironephthya pendula,

small anastomosing solenia; the whole ccoenenchyma is studded with numerous spicules of

varying size with their long axes vertical, to the presence of which the stem owes its

rigidity. In the branches (text-fig. 3) the main canal will have divided into several

secondary branches, which in their turn branch further until they terminate in a polyp-

cavity. The solenia of the branches are few in number; quantities of spicules are again

found everywhere.

In the stem of Chironephthya (text-fig. 2) there is a ring of about eight canals

surrounding a mass of coenenchyme practically without spicules ; outside this rirg the

cenenchyme is filled with spicules, but their absence from the centre makes the stem

very much more lax than that of Siphonogorgia. In the branches (text-fig. 4) the canals

become immense and the ccenenchyme is very much reduced, and in consequence of there

being no solid mass of tissue strengthened with spicules to keep the branch stiff and

rigid the walls collapse and give the grooved irregular effect already noticed.

In this family, as Professor Hickson (18) has already pointed out, a study of the

spicule arrangement in the polyps is disappointing, for no single colony or even branch

of a colony has exactly similar polyps, but the extent of the variation is not very great ;

in fact, a general type of arrangement can be given as a diagnostic character of the

22 MISS RUTH M. HARRISON ON NEW ALCYONARIA

eenera. In Chironephthya there are generally two to four spicules arranged “ en

chevron” in the points of the anthocodie, while in Siphonogorgia the spicules of the

points are arranged irregularly or practically straight and not inclined towards one

another. But even among the Chironevhthye there are considerable variations in the

armature of the polyps. The three original ‘ Challenger’ specimens are so similar ia

form and general spiculation that Prof. Hickson suggests that ‘it will be found in the

future that it is not advisable to recognize in them more than one species.” Having

had an opportunity of examining the actual specimens T doubt this. The polyp of

Fig. 3.—A transverse section through a branch of Siphonogorgia rotunda.

Fig. 4.—A transverse section through a branch of Chironephthya pendula.

C. dipsacea is entirely different from that of the other two ; and although I admit that

CO. crassa and C. scoparia are probably the same species, I think C. dipsacea should be

kept distinct, or at any rate notified as a distinct variation. I append three camera

drawings (Pl. 6. figs. 61, 62, 63) of the polyps of the ‘ Challenger’ specimens, which have

not been figured before. It will be seen that the polyp of C. dipsacea is not only smaller

but is much more like a Siphonogorgia. Another very characteristic feature of

Chironephthya is the presence in the partition-walls of a large number of minute

elongate spicules averaging about 0:25 0:02 mm., pointed at both ends and beset with

short spikes, and generally tinged with a paler shade of the characteristic colour of the

colony. For example, in the three specimens of C. variabilis these spicules are orange,

red, and pink respectively. These characters seem to me to express in a decisive manner

what Wright and Studer originally meant when they said that ‘‘ the habit of the colony

was more suggestive of Nephthya,” and are of far more importance than such characters

as the retractility of the polyps or the arrangement of the spicules of the anthocodiw.

Asa matter of fact, the polyps of Chironephthya are seldom retractile, and there are

FROM THE INDIAN AND PACIFIC OCEANS. 23

generally four spicules in the points of the anthocodize arranged “en chevron”; but the

complete retractility of C. stphonogorgica and C. retractilis and the armature of the

polyps of C. dipsacea show that the characters are not infallible. Therefore until

a series of intermediate forms is described it will be found convenient to distinguish

Chironephthya from Siphonogorgia by the mode of branching of the canal-system. This

is the course I have adopted in the present report, and in the systematic part will be

found the necessary readjustment of the already-described species.

With regard to the genus Solenocaulon, Janower (22) has given such an excellent

historical review that I need only here refer to it.

Of the four Solenocaulons in this collection, one is undoubtedly Hickson’s new

species S. ramosum* and calls for no special comment. ‘The other three form an

interesting series, and as I believe them to be all the same species I shall refer to them

as A, B,and C. The first most noticeable feature common to all three specimens is

that they are unbranched—that is to say, that each colony consists of a single straight

hollow main trunk which gives off small lateral twigs, with polyps borne both on the

twigs and the main trunk; there is no extensive branching such as Janower figures in

tne puotograph of Gray’s original S. tortwoswm (22) or Genth’s figure of S. tubuloswm (11).

The second striking feature is the retractility of the polyps. In A they are very

much expanded, a conical calyx projects from the smooth surface of the main trunk

or twig, and the polyp-heads project conspicuously beyond. In B the same thing

occurs, but not so markedly. In the flattened tubular nature of the little branches

both these forms resemble S. tubulosum (Genth). In C the polyps are completely

retractile, and only a very slight elevation marks their position externally. In this

and in the solid grooved appearance of the twigs the colony resembles S. tortwosum.

With regard to the solid axis about which there has been so much controversy: in

A and B there appears to be a “ porous calcareous rod... . . which does not break up on

boiling in 5 °/, potash.” This is shown in text-figs. 5 and 6. Text-fig. 5 is a transverse

section through the main trunk, and text-fig. 6 a transverse section through a terminal

twig; in both this porous rod is obvious. It is absent in the stalk, of which a quadrant

is shown in text-fig. 7. When Germanos (12) made his classification, in which he relied

so much on the presence or absence of a “ solid axis,” I doubt that he ever meant to

imply more than a “porous rod,” such as is shown to exist in the present specimen.

Turning now to specimen ©, which outwardly resembles S. tortwosum, the circumstances

are different, for here the “ porous rod” is not continuous, but appears to consist of

a series of calcified centres in which the spicules are fused together as in A and 5,

alternating with tracts in which the spicules are disposed quite loosely in the ccenenchyme.

This is shown by a comparison of text-figs. 8 and 9, which are two sections from the

same series: text-fig. 8 is a transverse section through a branch and a lateral hole, and

shows the porous rod; text-fig. 9 is taken just below the lateral hole where the main trunk

has become tubular again, the porous rod is entirely absent. It will be noticed in text-

fig. 8 that there is a similar calcification in the branch, but I am quite unable to find

* T have changed the feminine termination of ramosa to the neuter ramosum, to agree with the neuter

noun.

any connection between it and the porous rod in the main trunk. There is no

appearance of this discontinuity externally.

less oval spicules, covered with very irregular warts or spines: the axis contains

elongated spicules beset with few blunt spines. In the tubulur colonies one might

expect to find that the spicules lining the tube would be of the same nature as those

of the bark: as a matter of fact, this is not the case. These spicules (to which I shall

refer as those of the “inner bark,” to distinguish them from those of the “ outer bark *)

resemble more closely those of the’axis, but they are very much shorter. The spicules

of both inner and outer bark are practically the same size in all three specimens. I

cannot find the great’ variability in length quoted by Janower: for instance, he states

that the length of the bark-spicules of S. éwhuloswm varies between 0-04 and 1°2 mm.,

and those of #8. toréwosum between 0:05 and 06 mm.; moreover, he finds spicules in

the axis of S. tortwosum only 0:03 mm. long. As he calls no special attention to the

minuteness of these spicules, and as there are instances in his paper where the decimal

point has been omitted, it suggests a doubt as to the correctness of the statement in

the one case, and what is meant in the other.

The result of a comparison of these forms, which have points of resemblance to

S. tortuosum on the one hand and to S. twbulosum on the other, leads me to Professor

Hickson’s conclusion that the two species are probably one and the same. At all

events, I am convinced that the three specimens in the present collection belong to the

same species, and I have accordingly called them S. tortwosum.

Il.—SYSTEMATIC PART.

Fam. NEPHTHYIDS.

Genus Sponeoves (Lesson, 1834).

Branching tree-like Nephthyidee whose polyps are always united in bundles protected

by one or more projecting spicules. ‘Three types are distinguishable :—

1. Glomeratz: branching slight ; polyp-bundles in smaller or larger rounded groups,

surface of polyp-bearing part consequently much broken up.

2. Divaricatee: branches much spread out and diverging from one another; polyps

scattered on slender terminal twigs and not gathered together in bundles.

3. Umbellatz: terminal twigs form distinct umbels. These umbels may be separate

from one another, or several joined together to form larger umbels, or all the umbels

or groups of umbels may form one continuous surface. In all cases the polyps are

found on the surface of the polyp-bearing portion.

Kiikenthal has reduced the number of described species to eighty-seven, of which

twenty-eight are new. In addition to these species are twenty-nine other deseribed

species, of which four are not given a position in his systematic scheme owing to their

inadequate descriptions ; sixteen have been referred to other species ; eight are referred

to the genus Spongodia under the new name Slereonephihya, of which two are new ;

and eleven are referred to the genus Nephthya. Since the publication of Kiikenthal’s

paper, Thomson and Henderson (51, 52, and 53) have described seven new species ;

FROM THE INDIAN AND PACIFIC OCEANS. 27

and I now add five more, bringing the total number of Spongodes up to

87+4+7+5=103 and Spongodia to 8. Considering the slight variations on which

many new species are formed, these numbers are probably far too large; but so long as

the present method of classification of the genus is adopted, it is necessary to record

details of variation.

The most interesting form in the present collection is undoubtedly S. biformata, in

which the flattened branches bear polyps of alternating sizes; a table of measurements

is given with the description of the species. It is most unfortunate that the cell-layers

are in such a poor state of preservation that it is impossible to make any histological

observations on it; but the regular alternation of long stalked and short sessile polyps

is sufficiently pronounced to suggest that a thorough investigation might prove

interesting to anyone who is fortunate enough to obtain a similar specimen fresh or

well-preserved. It is probable that polyps of alternating size occur in all species that

have flattened foliate branches. Such appears to be the case in S. rubescens, but the

lower branches are all so much broken that it would be rash to make a definite

statement.

Lastly, I do not follow Kiikenthal in changing the name Spongodes to Dendro-

nephthya. The name Spongodes was invented by Lesson 73 years ago, and Kiikenthal can

find no better reason for changing it than its similarity to the allied genus Spongodia.

The similarity, if apt to be confusing, is not, in my opinion, sufficient to justify the

change, and throughout I have employed the original name.

SPONGODES ELEGANS, sp. n. (PI. 3. fig. 2; Pl. 4. figs. 26, 27; Pl. 5. figs. 36, 37.)

Belonging to the Divaricate cervicornis group of Kiikenthal. Length 10 em., breadth

6 em., sterile stalk 3°55 em. Main stem divides into two branches, each of which divides

again into two, and these further subdivide into numerous twigs. ‘lwo lower branches

form a flattened collar nearly encircling the stem. Polyps on stalks of 1 mm. in

clusters of 4-S; one large spicule projects sometimes as much as 2mm. Anthocodia

has 8 double rows of 4-6 spicules arranged en chevron, outermost larger and projecting

beyond bases of tentaéles. ‘Tentacles with double row of irregular colourless spicuies.

Stem-spicules : straight- or branched spindles, or definitely tri- or quadriradiate forms,

1°35 X0°'2 mm. or 0°45 0-4 mm. from arm to arm. All covered with large warty

projections. Branch-spicules: spindles only, of very varying size, 4:0X0'4 mm. to

0°2x0:05 mm. Larger spicules with warty projections ; these become less numerous

and prominent in the smaller forms. Spicules of the supporting bundle may reach

55035 mm. Spicules of partition-walls: stem closely filled with spicules of quadri-

radiate type varying in size between 0°1X0°02 and 0°-4X0°35 mm. In the branch

partition-walls spicules are less numerous, of spindle type, 1-40-25 mm.; also minute

spicules 0°1 x 0:02 mm., with forked extremities.

Colour. Sterile stem a light brick-red; main branches white, shading gradually from

pink to red twigs. Polyps red, with white tentacles.

SPONGODES RUBESCENS, sp. n. (Pl. 8. fig. 1; Pl. 4. figs. 28, 29; Pl. 5. figs. 30, 31.)

Belonging to the Divaricate rvigida group of Kiikenthal. Length 8 em., breadth

45 cm., sterile stalk 2°75 em. Whole colony very firm and rigid. Main stem divided

into numerous short branches, which subdivide into smaller branches and twigs,

bearing polyps in groups of 2-8 at about right angles to branch. Lower branches

flattened: one encircling stem for about one-third of its cireumference; others form

flattened plates with polyps borne all round the edge. One spicule projects beyond

polyp for about 1 mm. Spicules of anthocodia more or less in 8 double rows, but

chevron arrangement not very distinct. Spicules project beyond base of tentacles.

‘Tentacles with double row of deep red spicules. Spicules of stem: curved spindles

covered with warty projections varying between 2°7x0'4 and 04x01 mm. Branch-

spicules: variation greater, between 5:-4%0°5 and 0:10:02 mm. . Partition-walls:

spicules of two kinds, both scaree—(1) large warty spindles, and (2) very minute

thorny spicules, 0°1x0:02 mm.; in the stem the spindles vary between 1:75 x03

and 0-1 0:02 mm., and in the branches between 3:0 x 0°5 and 0:1 x 0:02.

Colour. Stem and main branches white ; secondary branches and twigs yellow; below

the bunches of polyps the spicules show a red core and there is a gradual transition

from yellow to red. Polyps red.

SPONGODES BIFORMATA, sp.n. (TI. 3 fig. 5; Pl. 4, figs. 28, 24, & 25.)

Belonging to the Divaricate cervicornis group of Kikenthal. Length 32 em.,

FROM THE INDIAN AND PACIFIC OCEANS. 29

breadth 2:0 cm., sterile stalk 1-4 cm. Two lower branches flattened, forming two

nearly complete semicircles round stem: above this are two lateral branches, and above

this again the main stem divides into two branches; these branches subdivide further

and bear polyps in bundles of 4-8 on stalks of 1-2 mm. Polyp-heads protected by a

bundle of 3-5 spicules, of which 2 or 8 project slightly beyond polyp-head. On the

lower flattened branches polyps are alternately borne on stalks or are sessile on the edge

of the leaf-like branch. The branching is very distinctly in one plane. Spicules of

anthocodia arranged en chevron in eight double rows, with 4-6 spicules in each row,

all about the same size and not projecting beyond base of tentacles. Spicules of stem

and branch: nearly straight spindles covered with warts. Tentacles have a double

row of comparatively large thorny spicules, 0:10:02. I am quite unable to find

any spicules in the partition-walls, and therefore cannot identify this species with

S. involuta (Kik.). The spicules in both stem and branches are longitudinally

disposed; below the polyp-heads they show a slight spiral twist.

Colour. Extreme base nearly white, all other spicules, stem, branch, anthocodia, and

tentacles yellow.

Hab. Bay of Bengal.

The following is a list of measurements of a series of transverse sections through a

flattened branch, where the alternation of stalked polyps with polyps sessile on the edge

of the leaf suggests dimorphism. My series takes in eight polyps—four stalked, and

four sessile; and although the following measurements do distinctly show that the

polyps are different in size, it must be borne in mind that the observation is a difficult

one; the polyps frequently are bent, and the figures can only be taken as approximately

correct.

The following species is a Spongodes from the China Seas, presented to the Oxford

Museum by Captain Chimmo :—

SPONGODES CHIMMOI, sp. n. (Pl. 3. fig.3; Pl. 4. figs. 20, 21, 22; Pl. 5. figs. 32, 33,

& 34.)

Belonging to the Umbellate florida group of Kiikenthal. Length 6°5 em., breadth

5:0 em., thickness 2°83 em., sterile stalk 25 em. Colony rigid, developed in one plane.

Stem has long stolons, some of which reach a length of 4:0 cm. Branches given off all

round stem; lower ones at right angles and upper ones vertical, but lower branches are

not flattened out. Polyp-bearing twigs very closely crowded together, so that the colony

has a very compact appearance and regular outline. Polyps in clusters of 8-16, at

about right angles to stalk, supported by bundles of (generally) three spicules, of which

one projects beyond polyp-head for 0°5 to 10 mm. Polyps measure 0°6X0°8 mm.

Spicules in eight double rows of 5-6 each, all about the same size and not projecting

beyond base of tentacles. Stem-spicules: irregularly disposed, various shapes and sizes.

i. Curved spindles thickly beset with blunt spines; ii. Spindles bifid at one end, thus

forming a three-armed spicule; iii. Spindles with spines of one side very much longer

than those of the other; iv. Long spines of one side grouped together in bunch, approx-

imately in middle of long axis; v. Long spines drawn out so as to form third arm, but

arm comes from middle of spicule, and not from bifid end as in ii.; vi. Large number

of much smaller spicules, some straight, some curved into semicircle, some with 3 or 4

arms. Spines disposed (a) evenly all over, (0) with large ones grouped together at one

end, or (¢) in one, two, or more tufts on different parts of spicule. Long spines may be

absent altogether, or spicule may appear to consist of large spines only and axis

reduced.

Spicules of branches and twigs elongate spindles with small blunt spines evenly

distributed all over surface. In main branches general tendency of spicules is to lie

transversely to long axis of branch, but in terminal twigs direction becomes longitudinal.

‘Tendency for spicules to lie transversely carried to marked degree in spicules of partition-

walls of stem; here long axis of spicule invariably placed in horizontal axis of stem.

Spicules large, some nearly straight, some curved, some bifid at one end, some have 3,

4, or 5 arms; all covered evenly with short, blunt, very numerous spines. Also a few

spicules irregular in shape with much reduced spines.

I_also found two bright red spicules in the branch partitions. These were much

smaller and thinner in proportion to the ordinary form of spicule, and spines very much

less prominent.

Tentacles without spicules, and can be completely folded over mouth to form an

operculum.

Colour. Stem and main branches white, gradually shading in the terminal twigs to

crimson, Polyps white. In the lowermost branches both twigs and polyps are white.

Fam. SrpPHOoNOGORGIID# (Kikenthal).

This family contains the two genera Siphonogorgia and Chironephthya, distinguished

by the following diagnostic characters :—

Genus SIPHONOGORGIA.

Stiff branching Siphonogorgiidee, with smooth, round, cylindrical stem and branches,

having one main central nutritive canal in the stem * which divides into several separate

* Tn making this statement I am not ignorant of Wright and Studer’s figure of a transverse section of S. hollikert

in the ‘ Challenger’ Reports, vol. xxxii. Aleyonaria, Suppl. pl. 6. fig. 5. Unfortunately I cut my sections and came

to the above conclusions after having inspected the British Museum material, so that I was not able to examine it

with this question of the branching of the canal-system in view. But when looking at the figure of the whole

colony on pl. i. of the same work, and seeing how extremely short, in fact almost non-existent, is the stem, it seems

probable that the section was taken at the base of a branch below the polyp-bearing portion but above the region

of “stem proper” after the main canal has begun to divide. Even if sections through other Siphonogorgids should

disprove the invariable occurrence of one central canal in the stem, the stiff smooth cylindrical stem and branches

caused by the cenenchyme being completely packed with spicules must, I fecl sure, remain as a specific diagnostic

character,

canals in the branches; ccenenchyme containing quantities of spicules; polyps capable

of complete retraction, and spicules of anthocodia generally not arranged en chevron.

Genus CHIRONEPHTHYA.

Branching Siphonogorgiide with a ring of nutritive canals in the stem, outside which

the ccenenchyme contains numerous spicules; in the branches the canals become larger

and the partition-walls: much reduced, large spicules are scarce, but small spiked spicules

abundant; polyps generally not retractile, and points of the anthocodia have 2-4 principal

spicules arranged en chevron.

Prof. Hickson has already suggested that Siphonogorgia pendula and 8. macrospina

should be referred to the genus Chironephthya; from the above definitions this suggestion

is amply confirmed. From the short diagnosis and the figure of S. sguarrosa described

by Studer from a manuscript of Kélliker’s, this species should also be placed in the genus

Chironephthya. I have also little hesitation in placing in this genus: (1) Kiikenthal’s

Spongodes indivisa, described as “Ubergang zu Siphonogoryia” and founded for two

specimens, and as the length given is only 9 mm., presumably this is the larger of the

two; (2) Thomson’s Stereacanthia indica, gen. et sp. nn. The description of the canals

and anthocodia corresponds so nearly with my definition of Chironephthya that it leaves

little room for doubt.

CHIRONEPHTHYA VARIABILIS (Hickson). (PI. 3. figs. 6,7; Pl. 6. figs. 48, 49, 50, & 51.)

The examples of this species are all broken fragments ; no single colony is complete ;

but I do not hesitate to put them with this species, on account of their general form and

mode of branching, the size and form of the spicules and their arrangement on the

anthocodize. The colour is very variable; my three specimens differ, and all are

different from the seven varieties described by Hickson :—

A.—Stem and branches pale yellow ochre, becoming slightly deeper in the terminal

twigs. Polyps orange.

B. Three varieties.—In all stem and branches are red, becoming deeper red in the

terminal twigs. Polyps bright yellow, pale yellow, and white respectively.

C.—Stem and branch pale pink. Polyps pale yellow.

Since the pieces are all somewhat fragmentary it is not possible to give exact measure-

ments of their size. Probably A was about 6-0 cm. long and B slightly larger. The

fragment C consists only of the base of a colony broken off at a height of 1°5 em., with

a single branch given off at about 0°75 cm. ‘The spicules from the wall of stem and

branches are spindles covered with warty projections. The measurements will be found

tabulated below. Spicules of partition-walls elongate spindles nearly colourless in A,

and pink in both B and C; also small very numerous thorny spindles, orange, red, and

pink, in A, B,and C respectively. Hickson describes about ten rows of parallel transverse

rows of spicules in the crown of the anthocodia. I cannot count so many in any of mine,

six or seven being the maximum; but in his figure he only draws the latter number.

The arrangement of the point-spicules is variable; the polyps figured on PI. 6. figs. 49

& 50 are both from the same terminal twig, but it is generally possible to trace four

spicules arranged en chevron, of which two are considerably larger.

CHIRONEPHTHYA PENDULA, var. BENGALENSIS, var. n. (Pl. 3. fig. 8; Pl. 5. figs. 41,

42; Pl. 6. fig. 58.)

Siphonogorgia pendula (Studer).

Three fragments 6°0, 5-0, and 2°5 em. in length respectively, probably all portions of

the same colony. Stem erect, cylindrical; branches and upper part of stem deeply

grooved. Polyps clustered on apices of terminal twigs also occur all along branches, and

SECOND SERIES.—ZOOLOGY, VOL, XI. 5)

34 MISS RUTH M. HARRISON ON NEW ALCYONARIA

a very few isolated ones borne directly on main stem and branches. Polyps not retractile.

Spicules of barren stem arranged irregularly, spindle-shaped, bearing large warty

prominences. Jn the branches the arrangement hecomes longitudinal and the spicules

themselves are longer and more slender. Partition-walls contain spicules of two kinds :—

(a) long spindles like those of the outer wall with warty projections, colourless; (4) small

thorny spicules of a crimson colour. Polyp-spicules: crown consists of about five rows,

points have each one large pair arranged en chevron, distal ends beset with small spines

directed forwards. 'Téntacles with single row of thorny transverse spicules.

Colour. Stem white, with a few scattered crimson spicules. Branches crimson, shading

to orange in terminal twigs. Polyps orange, with colourless tentacles.

The species agrees very closely with Studer’s description of Siphonogorgia pendula,

which, as has been already shown, should more correctly be called Chironephthya pendula.

It differs from it in the immense size of the spicules of the partition-walls and in details

of colour. With regard to the latter, colour is such a very variable feature that it

cannot be taken as a character of any specific value; and as to the latter, although

a point by no means unimportant, it is scarcely justifiable to create a new species on

a single character when the agreement in other points is so close. These large spicules

occur‘ near the base of the colony, and it is quite possible that Studer took his sample

from the upper branches, where they are absent. So that it seems safer to retain it in

the species Chivonephthya pendula as variation bengalensis.

Hab. Bay of Bengal.

CHIRONEPHTHYA SIPHONOGORGICA, sp. n. (Pl. 3. fig. 9; Pl. 5. figs, 48, a & 6;

Pl. 6. fig. 56.)

One small complete colony, 15 em. high, dividing at a height of °75 cm. into two

branches, A larger colony 5°5 em. high, but with basal attachment wanting. Branches

few in number, not further subdivided and directed obliquely upwards. Polyps borne

directly on main stem and branches, and five occurring on stem below the first branch.

A definite calyx surrounds each polyp, into which it is completely retractile, and the

calyx is capable of closing over the retracted polyp-head. Spicules of stem and branches

disposed longitudinally, somewhat loosely packed together ; long curved spindles thickly

beset with small rugged warts. The canal-walls contain somewhat blunter spindles with

Jarger but fewer warts. All these spicules are a uniform bright coral-red. The polyp-

spicules are small and smooth ; the crown has about five transverse rows and each point

six to eight spicules with an ill-defined chevron arrangement. All polyp-spicules are a

transparent bright yellow. Tentacles are colourless, contain no spicules, and bear long

slender pinnules.

This species has many points of resemblance to a Siphonogorgia, such as the complete

retractility of the polyps and the ill-defined chevron arrangement of the point-spicules,

but the structure of the stem and branches leaves no doubt that it should be referred to

the genus Chironephthya.

SIPHONOGORGIA ROTUNDA, sp.n. (PI. 3. fig. 18; Pl. 5. figs. 38 & 39; Pl. 6. fig. 64.)

Two colonies, 23 and 20 cm. long respectively. Stem and branches solid, smooth,

rounded. Branching not very great. Polyps borne all round stem, main and sub-

branches. Lower part of stem barren. Polyps nearly completely retractile, borne at

right angles to stem and branches. Spicules of outer walls blunt spindles covered with

numerous low warts, size fairly uniform. Spicules of partition-walls of varying sizes,

some larger than those of outer wall, and numerous quite small forms. In the polyp

there are about five spicules in each point directed vertically upwards, below this are

about eight spicules arranged en chevron, and below this a crown of about six transverse

rows.

Colour. Stem and branches flesh-coloured, polyps white.

with warty projections ; (2) long slender colourless spicules with a considerable dark core

and beset with few spines. In the branches large pink spicules are absent. Spicules of

partition-walls very similar to those of outer wall, but pink coloration much fainter.

Besides these two kinds there also occur much smaller spicules with thorny projections.

Polyp-spicules: crown with about six transverse rows; points with two large spicules

arranged en chevron, and smaller spicules irregularly disposed between them. ‘Tentacles

with a single row of small thorny spicules placed transversely.

espalier pear-tree ; branches at nearly right angles to stem, inclined to bend downwards,

and very slender. Polyps spirally arranged, with a terminal bunch of five ; not retractile.

Spicules of the outer wall longitudinally arranged, of two distinct kinds :— (1) a few large

straight spicules, pointed at both ends and thick in the middle, with a considerable dark

core and beset with spiny warts ; (2) numerous small blunter spicules covered with low

warty projections. Spicules of the partition-walls: numerous small, fine, thorny spindles,

one or two of which are tinted a very pale pink. Polyp-spicules: crown with about

eight transverse rows, and points with about three to five spicules arranged en chevron.

Tentacles have a single row of irregular transverse spicules.

36 MISS RUTH M. HARRISON ON NEW ALCYONARIA

Colour. Base of stem a rosy purple, all the rest of colony, branches, twigs, and polyps

a pure white. This absence of all colouring-matter above the sterile stalk is a very

remarkable and striking feature.

Hab. Macclesfield Bank, Admiralty Islands.

CHIRONEPHTHYA HICKSONI, sp.n. (PI. 5. fig. 46; Pl. 6. fig. 57.)

One complete colony, 10 cm. high, 5 cm. broad, sterile stalk 2 cm. Stem erect,

cylindrical, dividing into two main branches ; short thick branches given off from these

and from stem, very slightly further subdivided and tend to be directed upwards. Polyps

on all branches, more numerous on terminal twigs; not retractile. Spicules of stem

irregularly arranged, blunt spindles covered with warty projections. In the branches

the spicules are arranged longitudinally ; they are much longer, some reaching 3°7 mm.,

with a solid opaque core making them extremely conspicuous; smaller spicules are also

abundantly present. In the partition-walls are large warty spindles and numerous

typical small thorny forms. Polyp-spicules: crown with about five transverse rows;

points with two or three spicules arranged en chevron, and smaller ones irregularly disposed

between them. Tentacles with a double row of spicules more or less dovetailed into

each other.

Colour. A uniform dull yellow, the opaque spicules of the branches standing out con-

spicuously; the tentacles only coloured a deep purple.

Hab. Macclesfield Bank, Admiralty Islands.

CHIRONEPHTHYA PURPUREA, sp.n. (PI. 3. fig. 11; Pl. 6. fig. 53.)

Colony 7°5 cm. long, 3:5 em. broad, sterile stalk broken off. Numerous branches

given off, all directed practically vertically upwards ; secondary branches few and small.

Polyps borne on the stem, branches, and twigs; more numerous on twigs, directed

vertically upwards and not retractile. Spicules of the outer walls: elongate spindles

covered with low rugged warts, of various sizes; some large, reaching nearly 4 mm., but

chiefly smaller ones not exceeding 1°5 mm. in length. Partition-walls crowded with

typical small thorny spicules; some are rather larger than the usual type, reaching

('4:mm. in length, but large warty spicules are absent. Polyp-spicules: crown with

seven or eight transverse rows ; points with three or four spicules arranged en chevron,

but when four are present there is very constantly only one spicule on one side of the

point and three on the other. Tentacles with a single row of small thorny spicules

placed transversely. All the polyp-spicules are fairly uniform in size and the polyp has

a very neat compact appearance.

Colour. Stem and branches white, becoming cream in the terminal twigs; polyps,

including the tentacles, a deep purplish red.

of outer wall: elongate warty spindles of very varying length, some large opaque

spicules of a conspicuous creamy-yellow colour reaching 3°35 mm. in length, others

smaller, numerous, some yellow and some red. Spicules of partition-walls: typical small

thorny spindles. Polyp-spicules: crown with about six transverse rows; points with

three to five spicules, somewhat irregularly arranged en chevron, of which one is generally

larger than the others. Tentacles with scattered small warty spicules.

Colour. Stem and branches deep crimson ; terminal twigs have a few large conspicuous

eream-coloured spicules, and are shaded from crimson to buff-yellow, terminating in

yellow calices. Polyps crimson: the contrast between the colour of calyx and polyp

gives a striking effect, and each polyp appears to be set in a yellow ring.

CHIRONEPHTHYA GRACILIS, sp.n. (PI. 5. fig. 40; Pl. 6. fig. 60.)

Colony 14 cm. long, sterile stalk 6cm. Stem divides into two main branches directed

vertically upwards, from which several short very slender branches arise. Polyps borne

on all branches, those on main branches sessile and single, those on terminal twigs in

groups and generally on short stalks. Spicules of outer wall: long slender spindles

with few small warts, of various sizes. Spicules of partition-walls: minute thorny

spicules of typical form and size. Polyp-spicules: crown with about five transverse

rows ; points with three to five spicules arranged en chevron, larger than those of crown

and with more pronounced warts. Tentacle-spicules comparatively large.

Colour. Stem and branches deep red ; polyps bright orange.

CHIRONEPHTHYA RETRACTILIS, sp. n. (PI. 6. fig. 55.)

Colony 5 em. long, consisting of one main erect branch and two short branches given

off at about 1:75 cm. from base. Polyps borne all round stem, completely retractile

within calyx, which projects from stem, and closes over polyp by all the spicules of the

calyx converging together in a point and not folding over as in a Siphonogorgia. The

polyps contract in the same way, and the result of this converging of spicules into a

point gives the effect of a number of sharp thorns projecting from the stem. Spicules

of outer wall: warty spindles of varying size, some curved, mostly straight. Spicules

of partition-walls: typical small thorny spicules. Polyp-spicules: crown with about five

transverse rows; points with four spicules arranged en chevron.

Colour. Stem and branches cream, with crimson-purple polyps.

Fam. BRIAREID&.

Genus SOLENOCAULON,

Stiff Briareidze, branching chiefly in one plane, consisting of a solid cylindrical stalk

and tubular or grooved main stem, branches, and twigs. The coenenchyme consists of an

outer bark containing loose spicules and an inner axis also containing loose spicules, but

in some places they may fuse to form a porous calcareous rod. Polyps may or may not

be retractile.

SOLENOCAULON ToRTUOSUM (Gray). (Pl. 3. figs. 14,15; Pl. 7. figs. 66 to 77.)

Three varieties.

A.—Lower portion, 25 cm. in length, of a colony, of which 11 em. is solid stalk bifid at

the end. Lateral branches short, coming off in pairs on opposite sides of lateral holes.

Polyps irregularly disposed on branches and main stem, but principally on the sides of

the branches and spirally up the stem; non-retractile, projecting beyond conical calyx.

Colour pale pink ; branches slightly deeper pink and stalk nearly colourless.

B.—Two specimens, in both the upper part is broken off. One 21 em. long, of which

10 em. is solid stalk. -Colony flesh-coloured. The other 15 cm. long, of which 4°5 em. is

solid stalk. Lateral branches come off very regularly on alternate sides of the main

trunk; tubular at their commencement, each becoming two parallel branches facing

one another. Polyps non-retractile, but conical calices, not so much developed as in

specimen A; borne on both sides of main trunk and branches.

C.—Portion of a colony 14 cm. long, but unfortunately broken at both ends. Lateral

branches borne on opposite sides of lateral holes, and the lateral holes are exactly opposite

one another, so that a front view of the colony looks like the tail of a kite and a side view

shows aseries of holes right through the main trunk. Polyps completely retractile, borne

at sides of main trunk and branches.

Colour pink.

In all three varieties the polyps are white. Spicules of the outer bark numerous,

small, and generally oval, entirely covered with large irregular warts. Length 0-04 to

01mm. Spicules of inner bark slender, elongate, beset with few small spines, rather

more numerous at the ends. Length 0-1 to 04mm. Spicules of axis similar to those

of inner bark in general appearance, but much longer. Length 0:18to0'78 mm. Axis-

spicules may fuse to form a porous calcareous rod in main trunk and branches.

Hab. Bay of Bengal.

SoLENOCAULON RAMosUM (Hickson). (Pl. 3. fig. 16; Pl. 7. figs. 78 to 81.)

Colony 85 cm. long, sterile stalk 30 em. Colony consists of a single upright main

stem, from which arise six incomplete and three complete belts and numerous slender

twigs from these belts. The specimen agrees with Hickson’s diagnosis in every point

except the greater size of the colony and the absence of all colouring-matter.

III. Notes on some Parasitic Copepoda ; with a Description of a new Species of

Chondracanthus. By May E. Batneripes, B.Se., F.L.S.

(Plates 8-11.) i

Read 5th November, 1908.

ALL the species described in this paper, with one exception, were collected and sent to

me by Miss Lebour, M.Sc. Durham, from fish brought in by the fishing-boats of North

Shields, Northumberland. I am very much indebted to her for her kindness in sending

them tome. <Anchorella stellata, Kr., was found on a Hake (Merluccius vulgaris, Cuv.)

bought at Sheringham, Norfolk. My work has been carried out in the Zoological

Department of the Imperial College of Science and Technology (Royal College of

Science), South Kensington. The classification is taken from Giesbrecht, but the

position of some of the wholly parasitic families in his system seems still a matter

of some doubt (cf. Dr. Calman*). Mr. Geoffrey Smith}, who has kindly given me

permission to refer to his work which is still in the press, places these parasitic families

(Caligidee, Lernzeidee, Lernzeopodidee, Chondracanthidz, Choniostomatidz) in the Tribe

Isokerandria, Giesbrecht, of the Suborder Podoplea, Giesbrecht. He has done this

with Giesbrecht’s consent and approval, and I have therefore adopted his system in the

following paper. With regard to the nomenclature of the appendages I have followed

Giesbrecht {| and Hansen §, who have independently arrived at the same conclusions.

This parasite seems to be very common in the nostrils of the Cod (Gadus morrhua)

(cf. A. Scott). T. Scott (1893) gives a short account and some figures of this species.

His figure (pl. 5. fig: 3) of the second antenna does not seem to be quite correct. ‘This

appendage (PI. 8. fig. 3, 4.°) is three-jointed. The basal joint articulates with a chitinous

plate, with which the mandible and first maxilla are also articulated (fig. 3, Ch.p.). From

the inner margin of this plate a chitinous rod springs which runs inwards and forwards

and is united to the front lip, which is stiffened at this point by a chitinous knob. The

second joint is quite short and forms the elbow of the appendage, which is doubled back

on itself; it bears two small sete. The terminal joint is nearly as long as the basal

joint and is very elaborate. There is a broad portion, which ends in a sort of paddle and

is covered with short spines. At the outer side of this, about the middle of its length, is

a strong sword-shaped blade, the outer edge of which bears a fringe of thick pectinate

setee. Close to the base of the blade is a strong curved claw (?) or seta. Three longer

and more slender setze lie between the blade and paddle. There are also two finer setz

on the inner side of these. This appendage is the same in both sexes.

The Mandible (PI. 8. fig. 4, Wd.) has a long tooth and one much smaller at its side,

and agrees closely with the mandible of a variety of this species found in the nostrils of

the Ling, Molva molva (Linn.), which T. Scott describes and figures (op. cit. 1902,

p. 288, pl. 22. fig. 16).

Behind the first maxilla and between it and the second maxilla is an oval chitinous

structure with a stout base (fig. 4, 8.7.); the oval portion is covered with fine hairs.

Claus, in his account of this species (op. cit. 1864, p. 375), describes and figures

(pl. 35. fig. 18d) a chitinous plate to which he says the palp (maxilla) appears to

belong ; this figure does not agree with mine ; but on the same plate (fig. 23 0) is a figure

of the mouth-parts of Bomolochus cornutus, and in this he shows a structure very similar

to that observed in B. sole@. Claus describes it as “the maxilla-plate with palp.”

Giesbrecht, in his account of the ‘‘ Paragnathe ” of the Copepoda (op. cid. 4, p. 75), gives

his reasons for regarding similar structures in the Hersiliidee and other Copepoda

as lateral outgrowths of the lower lip and he calls them, therefore, side lips

(Seitenlippen). There can be no doubt, I think, that this is the true explanation of

these structures in Bomolochus solee—i. e., they are outhrowths of the lower (hind) lip,

and are morphologically quite distinct from the first maxilla. Giesbrecht considers that

the correct terms to use for the parts of the mouth are fore lip (Vorderlippe), hind lip

(Hinterlippe), and side lip (Seitenlippe). The specimen from which the drawings were

made measured 1:53 mm.

The Male (P1. 8. fig. 2) is much smaller, one specimen measured *71 mm., another

‘Simm. As the male has apparently not been figured before, a drawing of it, enlarged to

SOME PARASITIC COPEPODA. AT

the same scale as the female, is given here. The abdomen is composed of three segments

and the caudal furea. The first and second antennz and the mouth-parts are the same

as in the female. The first maxillipeds (fig. 5) are quite different; they are very

conspicuous, and serve at once to distinguish the sexes. Claus describes them (op. cit.

p- 877) and also the swimming-feet, the fourth pair of which differs somewhat from

those of the female.

All the specimens examined were from the nostrils of the Cod (Gadus morrhua, Linn.).

Family CHONDRACANTHIDS.

Genus CHonpRAcANTHUS, De la Roche (1811).

CHONDRACANTHUS INFLATUS, sp. n. (Pl. 9. figs. 9-15.)

General Appearance (female).

In appearance the female is very stout and swollen, the body being curved slightly as

shown in the figure (fig. 9). The head is separated from the body by a deep constriction,

and bears a pair of strong curved hooks, the second antenne ; these project considerably

beyond the ventral surface of the head, and by means of them the parasite is attached to

its host. There are no traces of the first antennze. The first thoracic segment is short

and rounded dorsally, and bears a pair of blunt bilobed appendages. The constriction

which separates this segment from the posterior one is less marked than the division

between the head and the first thoracic segment. Traces of three more segments can be

made out, the first of which is the shortest and bears another pair of bilobed appendages.

The postabdomen is very short and projects beyond the genital segment; it is roughly

pyramid-shaped with a blunt apex, and shows traces of two or perhaps three segments.

On the last of these are a pair of small caudal furca. Just anterior to the furca are the

openings of the oviducts. It is doubtful whether these are true segments or only

secondary foldings. There are no lateral processes. Two transparent tubes run down

each side of the genital segment beneath the dorsal surface. On the ventral side of the

minute postabdomen the oviducts with narrow necks and wide ends can be seen

(fig. 14, Od.). They open to the exterior on the sides of the abdomen, at a point a

_ little posterior to the middle of its length. No ovisacs were present, and the ova inside

the body were not fully developed. A minute male was attached to the female just

above the abdomen on the ventral surface (tig. 9, ¢ ).

Appendages (female).

First Antenne.—Not developed.

Second Antenne.—A pair of stout hooks on a broad basal joint, very similar to these

appendages in other species of Chondracanthus,

Mouth-parts (fig. 13).—Two pair of appendages (the second maxille and _ first

maxillipeds) and part of a third pair (the first maxillee) are situated posterior to the

48 MISS MAY E. BAINBRIDGE ON

fore lip. This is long and curved, with two small prolongations at each side (#./.), and

completely covers the mandibles.

Mandibles (fig. 12, Md.).—Curved blades, the outer margin bearing sharply pointed

teeth, the inner margin covered with much smaller teeth.

First Mavxille (fig. 12, Mv.1).—These are posterior to the mandibles, and are partly

covered by the fore lip. They are flat ovate appendages, bearing each two small

curved set.

Second Maville (fig. 12, Mx.2)—Apparently three-jointed. The last joint bearing a

bluntly pointed blade with curved teeth on the outer margin : below the teeth is a delicate

tongue-shaped seta.

First Mavillipeds (fig. 12, Maxp.1).—Three-jointed, the terminal joint bears a strong

short claw (there is no small tooth on the upper margin of the claw as on the same

appendage of OQ. cornutus). The sheath of this claw is covered with fine bristles.

The hind lip, which is leaf-like in shape, hangs down dorsally to these appendages,

the posterior margin reaching to about the level of the first maxillipeds. Two chitinous

structures of unknown function can be seen near the lower edge of the lip (fig. 18, H./.),

Thoracic Appendages (fig. 9, F.1, F.2)—Two pair. They are stout and project a short

distance beyond the margin of the body. ‘The ends are blunt and bilobed and are

covered with fine bristles.

General Appearance (male).

Seven segments can be distinguished including the cephalothorax. The last abdominal

segment bears the caudal furca. A wide intestine full of granules fills up a large

portion of the body (fig. 10, Z.). There is a large pigment-spot posterior to the second

antenne (Pg.). The mouth-parts are situated a considerable distance behind these

appendages.

Appendages (male).

First Antenne.—Four-jointed, slender. The terminal joint bearing three taste-hairs

or setee at its extremity and a tiny seta at its base. One seta on the third joint and one

on the second joint above its junction with the basal joint, on which is a very small seta.

Second Antenne.—Two-jointed, very stout with a strong terminal claw. The male is

attached to the female by these appendages.

Mouth-parts:—The mandibles and first maxille are not visible, being covered by the

fore lip.

Second Maxille.—Somewhat shorter than the maxillipeds. Three-jointed, the terminal

joint bears a stout claw and a small seta.

First Mawillipeds (fig. 11).—Three-jointed, and similar to the second maxille.

Thoracic Appendages (fig. 15)—Two pairs; apparently biramose. Inner branch

paddle-like, bearing a long slender seta and a very short one at its distal end. Outer

branch club-shaped, more slender, bearing one short seta at the end. These limbs are

very minute, measuring only ‘04 mm.

Habitat. A single specimen of a female with a male attached was found on the gills

of Raia radiata.

This Chondracanthus seems to be somewhat like Olsson’s * Chondracanthus annulatus,

and at first sight, in spite of the great differences in size (5 mm. Ch. inflatus, 10-12 mm.

Ch. annulatus), I thought it might be a young female of Olsson’s species. There are,

however, two important points of difference. Olsson says both the first and second pair

of antennz are very minute, and he mentions and figures short posterior processes,

which, however, he describes as shorter than the tail (abdomen). In the specimen from

the Starry Ray (Raia radiata) the first antennz are not developed, but the second

antenne are very large and strong, and there are no posterior processes. The male of

Ch. annulatus (length 14 mm.), as far as can be made out from Olsson’s description,

would seem to be very similar except in size to the male described above. Although it

is very unsatisfactory to establish a new species from a single specimen, it seems in this

case necessary to do so. The complete absence of posterior processes is remarkable,

these structures being usually developed in species of Choudracanthus. Chondracanthus

brevicollis, Kllr., described and figured by Kroyer f, is the only species of this genus

known tome which is without posterior processes, and indeed it seems somewhat doubtful

if it should be placed in this genus at all. Kroyer himself remarks that this form seems

somewhat aberrant, owing to the peculiar structure of the first thoracic limbs and the

abdominal appendages (the caudal furea is well developed in Ch. brevicollis). The host

of this species is not given; locality Moluccas, East Indies.

Lerneopoda cluthe has been described and figured by T. Scott, but the following

notes and a few more figures may be useful. This species seems to be very closely allied

to Lerneopoda longimana, Olsson {, a species which the Swedish naturalist found in

very large numbers (he mentions having more than 3800 examples, and says he had

seen ten times as many) on the gills of Raia fullonica, and at times very frequently on

Raia batis, also from the Skager Rack. T. Scott's specimens of L. cluthe were also

taken from the gills of Raia fullonica, Firth of Clyde; but although closely allied it

would seem that these two species are distinct. Olsson’s specimens of L. longimana

measured from 7-8 mm.; the neck was not quite twice as long as the cephalothorax,

and the egg-sacs equal to the neck in length. As already stated, Olsson examined

a very large number of specimens, and he says that in all these the specific characters

mentioned above were very constant. TT. Scott’s specimens measured 5 mm., and the

neck appears to be decidedly shorter than in Olsson’s specimens. Scott found and

described the male; but Olsson, although he examined such large numbers, never

saw amale. This point is interesting, as the simultaneous occurrence of the two sexes

varies considerably in different species.

About twelve specimens of a Lerneopoda, all females, from the gills of Raia radiata,

were examined by me. These agreed closely with Scott’s specimens in size and other

particulars, and are therefore placed under his species.

The measurements are given below.

The body of the female (fig. 24) was full of large ova. The ovaries (Ov.) are situated

on either side of the genital segment where the body begins to widen out below the

neck. The ovisacs are short, the ova being very large and apparently hexagonal in

shape owing to pressure. Some ova found in a shrivelled ovisac, which had shed most

of its contents, were found well-developed (January), the larva showing the abdomen

already developed and two pair of swimming-feet. There is a wide intestine (Z.es.) full

of granules which seems to run straight from the mouth-tube, widening out in the genital

segment and narrowing again posteriorly. The genital openings are situated on the ven-

tral surface on two slightly raised knobs, between which lies the minute postabdomen.

Mandibles (fig. 25).— Length °18 mm. Slender, irregularly toothed. Four large teeth,

between which are three very small ones. Following these seven teeth are four more,

which are very thin and delicate. Eleven teeth in all.

The organ of attachment by which the parasite is joined to its host is most remarkable ;

it will be described in detail in another paper on the organ of attachment in the family

of the Lernzeopodidee.

A single specimen of what I take to be this species was found in the spiracle of the

Piked Dogfish (Acanthias vulgaris). P.J. Van Beneden’s description and figures of

this species, which he obtained from the nostrils of the Sting Ray (Zrygon pastinaca),

SOME PARASITIC COPEPODA. 51

are not very satisfactory. He says the head passes insensibly into the thorax without

narrowing to form a neck, so that at the first glance you do not know where the

head is. This description certainly does not apply to the parasite from the Piked

Dogfish; but after a careful comparison of my specimen with Kurz’s figures and

description (op. cit.) of Brachiella pastinaca, I think it is correct to identify it as that

species. ‘I. Scott obtained two specimens in the nasal fosse of Trygon pastinaca, Linn.,

but unfortunately they were lost in the post and he was not able to give any figures

(op. cit. p. 278). It would seem to be a somewhat rare species.

The curious position of this parasite (PI. 8. fig. 6) is very remarkable. The head is

thrown back, the arms (first maxillipeds) stretched out, and the posterior processes

turned up almost at right angles to the body. Kurz’s description of the general form

of the body is accurate, but a short account of the appendages and some more figures

may be useful. The cephalic shield which covers the dorsal surface of the head is made

up of two plates, down the sides of which run strong chitinous rods of a yellow colour.

There is a more slender rod of chitin between the two plates.

Appendages (female).

First Antenne (Pl. 9. fig. 8, A.1).—Slender, four-jointed, the terminal joint bearing

three setze of different shapes, and the second joint one small seta.

Second Antenne.—Biramose, thick, and blunt; outer branch thicker than inner

branch, bearing one or two small hooks and covered with fine bristles.

Mandibles (PI. 8. fig. 7).—These lie inside the mouth-tube and are long and slender ;

they differ somewhat from Kurz’s description and figure (p. 390, pl. xxvi. fig. 36). He

mentions three principal teeth with three smaller teeth alternating with them, the five

following teeth, with the exception of the first, being considerably smaller. In the

specimen from Acanthias vulgaris there are three large curved teeth. Between the two

first of these are two very small teeth (only one is shown in the figure). These tive

teeth are followed by two straight and sharply pointed teeth, and these again by two

more, which are very slender and delicate. There are nine teeth in all. Beyond the

teeth the inner margin is produced into a rounded cutting-edge.

At the sides of the mouth-tube, just anterior to the first maxille, are a pair of slender

clawed appendages (PI. 9. fig. 8, p.), each composed of a stout basal joint and a slende.

curved claw. Thompson *, in his description of Brachiella parkeri, mentions and figures

somewhat similar structures; he calls them ‘“ maxillary palps.”

First Maxille.—See Kurz (op. cit.).

Second Mazille (Pl. 9. fig. 8, Mx.2)—Kurz does not describe these appendages,

but his figure (pl. xxvii. fig. 45) corresponds fairly well with my drawing. They are

two-jointed, the basal joint stout and bearing on the inner margin, just below the

articulation of the terminal joint, a small pad covered with tiny bristles. About the

middle of the inner margin is a small seta, and below this another small pad with

bristles. The terminal joint is slender and curved, its edges having strong clutinous

supports ; at its end is a curved claw with a small tooth on its inner edge. At the base

of this claw is a small papilla with a single hair. Near the base of the terminal joint is

a small seta.

First Mazillipeds.—Short and separate along their whole length. At the base of

the cup-shaped organ of attachment they are united. The parasite was so firmly

fastened to its host that it was necessary, in order to obtain the specimen undamaged, to

cut away some of the tissue of the host. The structure of the tenaculum will be

described in another paper.

One specimen of what I take to be this species, or one closely allied to it, was obtained

from the gills of the Long-nosed Skate (Raia oxyrhynchus) in May. It was a female

without ovisacs. The parasite was so firmly attached to its host that it was only

dissected out with great difficulty.

General Appearance (female).

The position of this creature is very remarkable (Pl. 9. fig. 16), the head

being bent backwards almost at a right angle with the body, so that the head

and first maxillipeds are nearly in a straight line. The arms are very long and

slender, almost the same thickness throughout their length, and only tapering

slightly at the distal ends, where they are united in a disc-shaped tenaculum deeply

imbedded in the tissue of the host. The head to the bend of the neck measures more than

half the length of the neck and genital segment together. The neck is slender and

short, passing gradually into the genital segment. From the ventral surface this

portion of the body is somewhat bottle-shaped, widening posteriorly. Near the hinder

margin the sides curve in, ending in two short lobes. The abdomen, which is roughly

square, lies between these lobes and projects a short distance beyond the genital segment.

On its dorsal surface near the sides are two stout processes borne on very short stalks.

On the ventral surface of the abdomen two indistinct segments can be made out: the

anterior is the shorter of the two and has a small thick-lipped slit down the centre. At

the sides and slightly posterior to this slit are two knobs; between the raised folds of

these lie the genital openings (Pl. 10. fig. 22, G.O.). The posterior segment is bluntly

rounded and has a slit down the centre, the opening of the anus (PI. 10. fig. 22, @.). In

the preserved specimen it was not possible to determine with certainty whether the two

slits were continuous or not.

The head is elongated, wider posteriorly, and becoming narrower towards the anterior

end, where it is bent over so that the mouth-tube is on the ventral surface. The dorsal

surface of the head is flattened. At the anterior end, where it is bent over, is a small

prominence with uneven edges (PI. 9. fig. 17, a); the first pair of antennze, which are

SOME PARASITIO COPEPODA. 59

curved backwards, are borne near the base of this structure. Between the second antenne,

and making an angle of 45° with them, is the long mouth-tube, which hangs downwards.

The upper and lower lips can be readily separated and the mandible is seen lying

between them. Posterior to the mandibles at the base of the mouth-tube are the first

pair of maxille. The second maxille are situated far behind the first pair, about half-

way between the extremity of the head and the bend of the neck. Their ends

are directed forwards and project considerably beyond the surface of the head. A

constriction can be seen at the back of the head and another where the body is bent

back; on this segment the arms are borne. Posterior to the bend is a narrow short

portion passing gradually into the wide genital segment. Indistinct traces of four

segments can be made out in this portion of the body. The first two subequal; the

next about one and one-third longer, the fourth about three times as long as the first.

It is doubtful if these are true segments. Two bands of muscle can be seen running down

the centre of the genital segment ; ata point which corresponds with the first constriction

behind the neck their continuation seems interrupted: this is probably a true segment.

These muscles run backwards almost to the base of the abdomen. On each side of them

are two large masses of ova extending forwards into the first segment. There is another

mass of ova beneath the ventral surface, and lying between these masses are a pair of

thick-walled cement-glands (Pl. 9. fig. 16, C.G.), which extend forward to a point about

the middle of the total length of the genital segment. From the side they can be seen

curving round in the prominences at the posterior margin of the body just above the

genital openings (fig. 16, G.O.).

Appendages (female).

First Antenne (PI. 10. fig. 23)—Two-jointed, basal joint one and a half times as long

as the terminal joint, which is slender, bearing two delicate tapering setee, one of which is

thicker than the other, and two more very small setze. Rather below the middle of this

joint is another small seta.

Second Antenne (Pl. 10. fig. 19).—Stout, biramous. The two branches are borne ona

stout basal portion which is not distinctly segmented. The outer branch is about the

same thickness throughout, with a blunt truncated extremity. This portion bears

three rounded knobs, the two outer smaller and more raised than the median knob.

All are covered with fine bristles and a few small hooks. The outer margin of this

branch is also covered with bristles. The inner branch of the main stem is not so

stout as the outer branch. The outer edge is covered with bristles, and above this

part is a rounded knob on which isa slightly hollow dise full of bristles with a small

seta at its base and another longer seta near the outer edge. On the inner side of this

disc is a strong sharp claw with a small seta at its base. The segmentation of both

branches is indistinct.

Mandibles (Pl. 10. fig. 20).—Four large teeth alternating with three small teeth:

these seven are followed by four more, the first two of which are longer than the other

two. Behind the teeth is a cutting-edge.

First Maxille (P1. 10. fig. 21)—Biramous. The outer branch bearing three long

tapering setee. The inner branch small and stump-like, bearing two small sete. The

SECOND SERTES.—ZOOLOGY, VOL. XI. 8

54 MISS MAY E. BAINBRIDGE ON

segmentation of this appendage is indistinct, but traces of two joints on the main stem

below the inner branch can be seen.

Second Maville (Pl. 10. fig. 18).—Very indistinctly segmented, traces of three joints

can be made out, the last bearing a short simple claw ; below this on the inner margin

of the same joint is a delicate short seta. Between the two appendages, at their base,

are two small raised folds. The outer free margin is much longer than the inner, so that

one appendage could not be dissected without tearing the other. The structure of these

appendages is peculiar and unlike those of other species of Brachiella. There was no

claw on the left appendage—it may, however, have been accidentally destroyed.

This species seems to be nearly allied to, if not identical with, Brachiella parkeri,

Thompson (op. cit.), from the gills of Raia nasuta and also a Stingaree (Zrygon sp. ?),

Otago Museum, but it differs from it in several particulars.

There is some difference in the size. The following are Thompson’s measures of

On a comparison of these figures it will be seen that my specimen is considerably

smaller, but it was without ovisacs and is probably a young female. Thompson, in his

brief account of this parasite, mentions and figures a pair of “ maxillary palps” at the

base of the rostrum; these appendages were not observed in the form now described.

The great length of the posterior processes, 10 mm. as compared with 4 mm. in the

British form, should also be noted. But, on the other hand, the position of the head in

a “nearly continuous line with the arm-like appendages and bent at right angles to the

genital segment” is very characteristic of my specimen. Also Thompson’s description

of the first maxillipeds (he calls these appendages “second maxillipeds”), as “ conical

protuberances which show no distinct segmentation” and which are situated “about

three millimetres from the extremity of the cephalothorax,” applies closely to the

structure and position of these appendages in the form from the Long-nosed Skate. I

have thought it better therefore provisionally to call this parasite Brachiella parkeri,

Thompson.

The structure of the tenaculum with its remarkable sucker will be described in

another paper.

This species seems to be fairly common on the gills of the Catfish (Anarrhichas lupus,

Linn.). There is considerable variation in the size of the female. One specimen

measured 4 mm. from the base of the first maxillipeds to the end of the abdomen.

The cephalothorax measured 6°5 mm. in length and the width of the genital segment

was 36mm. In another specimen these measures were respectively 2°3 mm., 4:4 mm.,

and 2°8 mm.

The Female.—Kriyer’s description of this parasite is good, but his figures are poor.

T. Scott (op. cit. 1900) also gives a short account and some figures of this species.

The square outline of the genital segment and the stout wavy cephalothorax, which

in life is doubled back and lies close to the dorsal surface, are very characteristic,

as is also the jerky movement of the head from side to side and the slow

movement up and down of the ovisacs. Kréyer mentions the peculiar move-

ment of the end of the cephalothorax. Slighter movements of the antennz and

second maxille can be seen. In life the colour of the genital segment is

yellowish and semi-transparent. A wide brown intestine with wavy borders runs

down the cephalothorax and can be seen as a conspicuous brown mass on the

ventral surface of the genital segment. The ova are paler in colour and each

shows two specks of brown pigment (February). The chitinous structures are

deep yellow. On the ventral surface (the side away from the cephalothorax), just

anterior to the abdomen and between the ovisacs, are two yellow chitinous spots (the

openings of the receptacula seminis); projecting from these in one specimen were

two semi-transparent packets in shape like long narrow pods: these are probably

spermatophores. On another female without ovisacs two globular semi-transparent

bodies were observed projecting from the openings of the oviducts. They measured

‘66 mm. in width and were ‘8 mm. long. Possibly they are the commencement

56 MISS MAY E. BAINBRIDGE ON

of the ovisacs? The muscular system will be described in another paper on the

attachment of this parasite.

The Male.—Males are found attached to different parts of the female, sometimes

on the cephalothorax or on the postabdomen, and in one case on the dorsal

surface. They are minute and easily detached, holding on by means of the claws

of the second maxille. In life they are semi-transparent and show no distinct

segmentation. A wide coiled tube, the testis (Pl. 10. fig. 29, 7.), fills up most

of the body; there is also a broad intestine (fig. 28, J.) with sacculated walls

which narrows posteriorly and opens where the carapace curves inwards (q).

The intestine contains numbers of brownish-green cells; these are probably the

excretory cells of Claus and are mentioned also by Wierzejski* in his description

of the males of Penella varians(?). Clear oil or fat-globules are present in

numbers in the digestive tube. Beneath the dorsal surface in the median line

is a patch of red pigment (figs. 28, 29, Pg.), and there is a less conspicuous

patch near the base of the first maxillipeds. At the base of these appendages

on each side is a small coiled slightly raised structure, which looks like the

opening of a gland (P.). Kurzt, in his description of the male of Anchorella

emarginata, a species closely allied to 4. rugosa, mentions two protrusible papillae,

at the extremities of which are the genital openings (fig. 11, gp.) and which are

situated behind the “second maxillipeds” (first maxillipeds). It seems doubtful,

however, from the position of these openings in A. rugosa whether they can be

genital.

The description given by Kurz of the appendages of the male of J. nt

(p. 401, figs. 11, 27, 28) seems to correspond closely with those of this species.

The Second Antenne (fig. 81) are much like his figure (fig. 28, a’), but he does

not mention two delicate setze on the paddle-shaped branch.

The Mandibles (Pl. 10. fig. 30).—The same as in the female, but much smaller

and more slender; the teeth do not appear to be quite so sharply pointed as in

Kurz’s figure (fig. 31) of the mandible of 4. emarginata.

The First Maxille (fig. 32).—See Kurz (figs. 27, 28, mz.).

The First Masxillipeds (Pl. 11. fig. 36)—Very stout and bearing strong claws.

There is a small tooth on the claw, which is doubled in and seems to work on

a pad covered with bristles. On the stout basal part of the appendage is a

seta.

(For synonymy and literature, see Bassett-Smith, op. cit. 1899, p. 505.)

Two females of what seems to be a variety of Anchorella uncinata, Miller,

were obtained from the fin of a Cod (Gadus morrhua),

General Appearance (female).

The animal is somewhat flattened and is invested by a loose bag-like membrane

(fig. 43). On the fin of the host where the parasite is attached is a large oval

swelling (s.). The tenaculum is deeply imbedded in this swelling, only a small portion

of the end of the chitinous stem being free. The two arms (first maxillipeds) are

short but distinct, and are only united at the base of the stem of the tenaculum. Two

glands open to the exterior on the transparent investing membrane close to the base of

the arms. Similar glands are present in the common form of this species. The

genital segment shows traces of three segments; the third is separated from the

preceding segment by a deep indentation at the sides. From this segment the pear-

shaped abdomen projects beyond the posterior margin of the body; it is borne on a stalk

(p.ab.). The cephalothorax lies close to the genital segment and is moderately stout,

increasing in thickness towards the head. In the larger of the two specimens it is a

little longer than the genital segment, in the smaller considerably longer. On the

sides at the end of the abdomen are two openings with thickened edges: two tubes can

be seen running down the abdomen to open at these points.

The tenaculum will be described in another paper.

The appendages are the same as in A. wucinata, Miiller. This variety differs

considerably from the common form in its general appearance, being much flatter, and

in the position of the cephalothorax. The curious pear-shaped swelling on the fin of

the host is remarkable, as the common form of Anchorella uncinata does not seem to

produce this swelling.

some drawings.

near the pectoral fin. They were all females and without ovisacs. The Hake was

purchased at Sheringham, Norfolk.

58 MISS MAY E. BAINBRIDGE ON

General Appearance (female).

The genital segment and cephalothorax are much flattened and are invested by a

loose bag-like membrane. The first maxillipeds (fig. 38, Mxp.') are rather more than

one-third of the length of the cephalothorax. They appear to be quite distinct, but the

investing membrane seems to be fused along the median line, so that the two appendages

cannot be separated. The ends are enlarged into two semicircular folds, between which

the tenaculum lies. In the genital segment on either side are two large thick-walled

cement-glands (C.G.). The relations of the genital apparatus were not easy to make out

in preserved specimens, but the following points may be noticed :—The ends of the ovi-

ducts have thick chitinous walls (Od.); they open on the raised knobs on either side of the

minute abdomen (G.O.). Two boat-shaped structures with chitinous walls lie at right

angles and dorsally to them, and are probably the receptaculum seminis (R.S.). At the

inner side of the thick wall of the oviduct is a smaller chitinous structure (2), lying

apparently dorsal to the receptaculwm seminis. Vejdowski*,in his paper on Tracheliastes

polycolpus, Nordm., figures structures not unlike these, but the canals which he observed

leading from either end of the receptaculum seminis to the external opening were not

made out in Anchorella stellata.

On the abdomen are two minute chitinous structures ; these are probably the external

openings of ducts leading into the receptacula seminis.

The appendages are very similar to those of Anchorella uncinata, Miiller.

The Mandible (fig. 42).—This is very irregularly toothed. The first tooth is large,

followed by two smaller teeth, the fourth is very long and prominent, the fifth and sixth

are smaller. Following these is a curved cutting-edge. There are six teeth in all.

In size these specimens corresponded very closely with those obtained on the

Hake by T. Scott.

IV. The Freshwater Crustacea of Tasmania, with Remarks on their Geographical

Distribution. By GEOFFREY WarTKIN Situ, W/.A4., F.L.S, Fellow of New Oollege,

Oxford.

(Plates 12-18 and Map.)

Read 19th November, 1908.

Parr I.—GENERAL.

HISTORICAL.

DURING a six months’ stay in Tasmania (October 1907 to March 1908), undertaken

at the suggestion and through the assistance of Prof. G. C. Bourne of Oxford, I visited

a great number of freshwater localities in the island with the object of making a

collection and study of the Crustacea. Tasmania is a particularly favourable place for

studying the Australian freshwater fauna, as its highlands are covered with numerous

large lakes and tarns, and the country everywhere is watered by large rivers and

streams.

Previous to my visit, the only naturalist who had made a study of the Crustacea was

G. M. Thomson, F.L.S. (Proc. Roy. Soc. Tasmania, 1892, p.51), who confined himself to

the Malacostraca from a few localities. Most of the Tasmanian genera are, however,

common to Victoria and New South Wales, so that the works of Sars and Sayce (see

Systematic Part) have been of great use to me in assigning species to their proper

systematic positions. Besides the discovery of several new forms of interest, I believe

that my collections are sufficiently thorough and cover a wide enough area to establish

clearly not only what are the dominant genera in Tasmanian freshwaters, but also

what genera characteristic of other countries are absent.

In the account of the localities visited and the nature of their Crustacean fauna I

confine myself to stating the most important physical characters; but if the reader is

desirous of knowing more about the nature of the country and the means of transit I

may refer him to my book, ‘ A Naturalist in Tasmania’ (Clarendon Press).

LocaLitizs ; WITH THEIR CRUSTACEA.

Tasmania falls naturally into three chief regions :—(1) The Greenstone Plateau. The

plateau itself, formed of igneous dolerite or diabase, occupies the centre of the island,

the various large lakes being situated on the tableland at an elevation of 2000-3000 ft.

above sea-level. The diabase plateau is everywhere flanked by Permo-Carboniterous

sand- and mud-stones, beneath which the diabase was originally thrust upwards. To

the east and south the plateau is broken up and irregular, with extensive undulating

plains in the lowlands formed chiefly of the sandstones, but with occasional high

upstanding mountains of diabase, e.g. Ben Lomond in the north-east, Mt. Wellington

and the Harz Mountains in the south. The waters in this region, where they flow

chiefly over the diabase, are very pure and unclouded; but where they flow over the

sandstones, especially in the valleys, they are yellow and cloudy.—(2) The North Coast.

The strip of the north coast is very varied geologically, with outcrops of granite and

basalt and rather extensive tertiary estuarine deposits, especially round the Tamar.—

(8) The West Coast. The west coast is a very mountainous and rugged district, the

mountains being formed of schists, and other metamorphic rocks of Archzean, Cambrian,

and Silurian age. The rainfall here is excessive (about 100 inches per annum) and the

mountains are clothed with forests of the evergreen beech (Fagus Cunninghami), which

replaces Eucalypts, characteristic of the other districts. ;

1. The Greenstone Plateau.

The Great Lake.—At about 3000 ft. above sea-level is an extensive sheet of water,

90 miles in circumference, but nowhere deeper than 20 ft. The water is always some-

what discoloured by the sand stirred up by the waves. Round the edges are blocks of

greenstone with a good deal of weedy growth. The Crustacean fauna is very rich both

in point of variety of species and in number of individuals representing them. Almost

all the species are confined to the shallow littoral zone, the dredge in the deeper zones

bringing up nothing but fine mud without any life. In the littoral zone I found a new

genus of the Anaspidacea, named Paranaspides lacustris (Proc. R. 8. ser. B, vol. 80,

p- 470, 1908), a transparent green Mysis-like shrimp attaining an inch in length.

Crawling about in the weeds the very handsome Phreatoicus spinosus (Pl. 12. fig. 7), a

new species, was abundant, and also the common P. australis (Pl. 12. fig. 1). In the

deeper muddier zone the straw-coloured P. brevicaudatus, sp. n. (Pl. 12. fig. 5), was

especially common. These three very distinct species were perhaps the commonest

Crustacea in the lake. Together with these were two abundant species of Amphipod,

Neoniphargus tasmanicus, sp. n., and Gammarus ripensis, sp. n. (Pl. 14. figs. 5-8 and

Pl. 14. figs. 23-26).

The only native fish which inhabit the Great Lake are the little Galaxias, or native

“trout,” G. auratus and G. truttaceus, which can never have been formidable enemies.

In the last 50 years the English Brown Trout has been introduced here and grows to an

enormous size in the lake (up to 25 lbs.). ‘The trout examined by me all had very deep

pink flesh, and their stomachs were full of the above-mentioned Malacostraca, so there

is no doubt that they chiefly feed upon the Crustacea of the lake. Tow-netting during

the daytime produced very little result, but at night a rather poor quantity of plankton

was obtained consisting of the Cladoceran Bosmina brevirostris, sp. n. (Pl. 16. fig. 1), the

first Bosmina to be taken in Australasia, and the common Cyclops albicans, sp. un.

(Pl. 16. fig. 8).

Lake Sorell.—This lake, at a rather lower elevation than the Great Lake, is cf a

64, MR. GEOFFREY WATKIN SMITH ON THE

similar shallow type with discoloured water. Owing to the absence of a boat I was

unable to explore it thoroughly. The littoral region of the lake seemed destitute of

Amphipods or Phreatoicus, but there were numerous prawns of the widely distributed

Aiphocaris compressa. The plankton was well-developed and consisted of the two

Cladocera Bosmina sorelli, sp. n. (Pl. 16. fig. 2), and Ceriodaphnia planifrons, sp. n.

(Pl. 15. fig. 17), and the Copepod Boeckella longisetosa, sp. n. (Pl. 17. fig. 18), belonging

to the Diaptomide.

Lake St. Clair is very different in type to the other Tasmanian lakes, being exceed-

ingly deep (in places 600 ft.) and the water absolutely clear and ice-cold. The elevation

is about 2500 ft. The dredge from the deep holes brought up absolutely nothing but

fine mud. Round the sandy margins the widely distributed Amphipod Chiltonia

australis was common. The plankton, which was exceedingly rich, consisted of

Bosmina rotunda, sp. n. (Pl. 15. fig. 18), Ceriodaphnia hakea, sp. n. (Pl. 15. fig. 10), and

the Copepod Boeckella longisetosa.

Mt. Wellington.—On the flat top of this mountain, at about 4000 ft., are numerous

small pools of clear water which never completely dry up, with blackish mud at the

bottom of them. In these pools the common Phreatoicus australis is abundant and

with it the little yellow Amphipod Neoniphargus montanus (Thomson).

In a few of the deeper pools the mountain shrimp Anaspides tasmanie is met with,

but this species is found in greater abundance in the deep pools of the mountain torrent

which rises on the top of Mt. Wellington and flows down into the North-West Bay

River. It does not occur, however, in this river below the Wellington Falls at about

2000 ft. In the little rivulets which everywhere course down the sides of

Mt. Wellington several Amphipods are found under the stones, viz. Neoniphargus

wellingtoni and Gammarus mortoni.

Round the base of the mountain in the smaller branches of the streams the smaller

species of crayfish or freshwater lobster, Astacopsis tasmanicus, is found, though not so

abundantly as formerly.

Harz Mountains.—These mountains lie at the extreme edge of the greenstone country

bordering on the West Coast Mountains. Near the top are several large and very deep

tarns of clear water: in them Anaspides tasmanie is very abundant, and round the edge

a little black Amphipod, Neoniphargus niger, sp. n. (Pl. 15. figs. 1-4). The plankton

consists of a very numerous bright red Copepod, Boeckella rubra, sp. n. (Pl. 18. fig. 1),

only found in these tarns and in similar tarns on the West Coast (Mt. Read).

Mt. Field has similar tarns to the above, which, however, I did not visit. Anaspides

tasmanieé is found here.

Ben Lomond.—On the top of this mountain, at an elevation of about 4000 ft., is a

shallow lake, Yule’s Lake, in which are very numerous Phreatoicus australis and

Neoniphargus yuli (Pl. 18. fig. 1).

Adventure Bay Lagoon, Bruni Island.—This is a large shallow freshwater lagoon,

only separated from the sea by a line of sand hummocks. The water is, however,

perfectly fresh, and the water-weeds and fauna are typical of freshwater. Phreatoicus

australis was abundant here—a curious fact, since otherwise the genus is found only at

FRESHWATER CRUSTACEA OF TASMANIA. 65

high elevations. Among the weeds the Copepod Brunella tasmanica (Pl. 18. fig. 6),

representing a new genus of the Diaptomidie, was very abundant. This genus was not

met with elsewhere.

Small Ponds Sc. round Hobart.—As was to be expected, the Entomostraca from the

small ponds and puddles did not yield anything of particular interest, some of the

species being identical with Australian forms, while all the genera, except Boeckella,

are of world-wide distribution. The large Boeckella robusta was common in small ponds

round Hobart. Ina very small rivulet at Huntingfields, at sea-level, I again met with

Phreatoicus australis and a Neoniphargus, N. exiguus, sp. n. (Pl. 14. figs. 1-12).

Lake Dulverton really belongs to this category, as, although it is of a large size, it

is entirely overgrown with weed. It was found to harbour only those Entomostraca,

such as Alonella, Macrothriz, Cyclops, &e., characteristic of small weedy ponds.

It had besides a Boeckella, .B. insignis (Pl. 17. fig. 4), and the widely distributed

Chiltonia australis. It may be mentioned here that the Prawn Xiphocaris compressa

is found all over Tasmania in streams and lakes where the water is cloudy and there

is a great deal of weed, and the same is true of Chiltonia australis. The only Phyllopod

obtained was the common Lepidurus viridis.

2. The North Coast.

In this district all the streams and rivers tend to be rather discoloured and there are

no extensive lakes. The rivers are characterised by certain fish which are entirely

absent from the rivers of the south, east, or centre of the island. These are the Black-

fish (Gadopsis marmoratus), the Cucumber Herring (Prototroctes marena), and the

Freshwater Flathead (Aphritis).

The Anaspidacea appear to be entirely absent from this region and also the genus

Phreatoicus. I also failed to find any Neoniphargus. Gammarus antipodeus (Pl. 14.

figs. 17-22) was found in a little limestone stream (Mole Creek) near Chudleigh. The

small Crayfish Astacopsis tasmanicus appears to be entirely absent, its place being taken

by the gigantic 4. franklinii, which may scale 8 or 9 lbs. ‘This huge species is found

in the rivers and even in the smallest rivulets along the north coast and on to the west

coast, but it is nowhere very abundant. On the north coast upon mud-flats and swamps

the Land-Crab or Crayfish, Hngeus fossor, is fairly frequent, though nowhere so

abundant as on the West Coast Mountains.

3. The West Coast.

The mountainous and forest-clad region is only opened up to the traveller in the

mining districts, where tracks have been cleared through the forest. The south-western

corner of Tasmania, where no mines have been hitherto opened, is uninhabited, and the

forests can only be penetrated by the traveller cutting a track in front of him.

Two localities were visited on the West Coast:—(1) The beech forest round the

Magnet Mine. Here the burrows of the land-crab, Lngeus fossor, were present in all

the moist gullies, and in one place, where a dam was being constructed for mining

purposes, the banks were absolutely riddled by these creatures, which seriously

66 MR. GEOFFREY WATKIN SMITH ON THE

interfered with the construction of the dam. Under logs and the fallen leaves of the

beeches, the Hopper (Zalitrus sylvaticus) was very abundant. In a little rivulet I

collected some specimens of the Amphipod Gammarus australis.—(2) Near the top of

Mt. Read, at an elevation of about 3000 ft., I visited a tarn of exceedingly deep and

clear water. In this tarn Anaspides tasmanie was fairly abundant and a species of

Neoniphargus, N. alpinus, sp. n. (Pl. 14. figs. 18-16). The water swarmed with the

little red Copepod Boeckella rubra (Pl. 18. fig. 1), so that the fauna of this tarn closely

resembled that of the tarns on the Harz Mountains. I was surprised here by the

quantity and tameness of the Platypus, which swam round our raft with the greater part

of their bodies exposed to view—no doubt owing to their little acquaintance with human

beings, as the tarn had only been visited at long intervals on two or three occasions by

miners.

GENERAL REMARKS ON GEOGRAPHICAL DISTRIBUTION.

From a zoological and botanical standpoint Tasmania belongs to what Professor

Baldwin Spencer (‘ Narrative of the Horn Expedition to Central Australia,’ 1895) has

called the Bassian Subregion of Australia, which includes Tasmania and Victoria south

of the Dividing Range of mountains. This subregion is characterised by a moderate or

great rainfall and a temperate climate.

The freshwater Crustacea of Tasmania are for the most part represented by closely

allied or, in some cases, identical species on the mainland of Victoria, and very few of

the commonest and most typical forms (e. g. Anaspides, Phreatoicus, Chiltonia, Neoni-

phargus, Gammarus, Boeckella) range north of the Dividing Range into tropical or

subtropical Australia. These characteristic genera of Southern Australia belong, in fact,

to an essentially temperate fauna, by far the greater number of species being found on

the high alpine ranges of Tasmania and on thé slopes of the Dividing Range of Victoria

and New South Wales. They are, however, again represented by closely allied species

in the temperate climate of New Zealand, especially in the subterranean waters of that.

island (Chilton, Trans. Linn. Soc. London, ser. 2, Zool. vol. vi. pt. 2, p. 163). These

facts are of the greatest importance in considering the probable derivation of this fauna.

Two of the most characteristic genera of the Tasmanian freshwaters, viz. the

Amphipod Chiltonia and the Copepod Boeckella, which also occur in the temperate

parts of Southern Australia, are represented not only in New Zealand but also in

temperate South America, where Boeckella has been several times recorded (see Daday,

Termés. Fiizetek, Bd. xxi. 1902, p. 201) and Chiltonia is replaced by the closely allied

Hyalella of Lake Titicaca and the southern ranges of the Andes. These two genera

(Chiltonia and Boeckella) are therefore confined in their distribution to the temperate

parts of the Southern Hemisphere, with the exception of 8. Africa. The Copepod

Boeckella occupies the same position in the Southern Hemisphere as Diaptomus in the

Northern, which in the south it almost entirely replaces. Although some of the species

occur in small ponds, the majority live in lakes and are particularly characteristic of the

cold highland tarns of Tasmania. The Parastacine group of Crayfishes has a similar

distribution, being found in New Zealand (Paranephrops), Tasmania and Southern

FRESHWATER CRUSTACEA OF TASMANIA. 67

Australia (Astacopsis and Hngeus), South America (Parastacus), and an isolated form in

Madagascar (Astacoides).

There is, therefore, a strong presumption in favour of the view that at any rate these

elements in the temperate Crustacean fauna of Southern Australasia have reached their

present range by means of an Antarctic connection between the southernmost projections

of Australia, S. America, and New Zealand—a connection which is now more than ever

postulated to account for the presence of common elements in the temperate fauna and

flora of these countries.

Starting with this strong presumption in favour of an antarctic derivation of certain of

the Tasmanian and Southern Australian Crustacea, it is interesting to examine another

element which has evidently been derived primarily from the Northern Hemisphere.

This element consists of the Amphipodan genera Gammarus and Neoniphargus, the

Cladoceran Bosmina, and probably the Anaspidacea.

The genus Neoniphargus, the members of which form so dominant a feature in the

Crustacean fauna of Tasmania, is very closely related to Gammarus, but it shows an

approach to the subterranean European genus Niphargus, especially in the form of the

first maxilla (Pl. 18. fig. 5), the inner plate of which is narrow and bears only two or

three plumed setze at its apex, in the small number of joints composing the secondary

appendage of the first antenna (PI. 13. fig. 2), and in the greatly reduced endopodites of

the last pair of uropods (PI. 18. fig. 18).

Undoubted representatives of the genus Gammarus also occur in Tasmania (e. g.

G. australis), and certain species (e. g. G. ripensis and G. antipodeus) are almost exactly

intermediate between the genera Neoniphargus and Gammarus (see Pl, 14. fig. 27) in

the structure of the maxilla and of the first antenna (Pl. 14. figs. 17, 22, 23). The

special resemblance of Neoniphargus to the European Niphargus may therefore be due

to convergence. However this may be, the occurrence of Gammarus and the closely

related Neoniphargus in the temperate region of Southern Australasia and in New

Zealand affords a peculiar instance of discontinuous distribution, because Gammarus

and its close allies are otherwise confined to the north temperate hemisphere, being

absolutely unknown from the tropics of either hemisphere. In enquiring how they

have reached their present position in Southern Australasia we must bear in mind that

‘temperature in this case, as in the case of all Crustacea, whether freshwater or marine,

is the chief condition determining the dispersal of these forms. There are two routes by

which they could have reached Southern Australasia, either through the tropics of Asia

and Northern Australia or else through South America and the lost Antarctic

connection. It is extremely difficult to see how an animal apparently incapable of

living in a tropical climate could have followed the first-named route, as there is no

range of mountains in the Eastern Hemisphere running north and south which could be

used by such an animal as a bridge to pass through the tropics; but in America there

is the range of the Andes to permit this migration. It may therefore be suggested that

the Tasmanian and Southern Australian Gammarus and Neoniphargus reached these

countries from the Northern Hemisphere through 8. America and Antarctica, and it is

reasonable to suppose that some of their representatives will still be found in the Andes.

68 MR. GEOFFREY WATKIN SMITH ON THE

The same theory applies with even more force to the Cladoceran Bosmina, which was

found by me as one of the chief constituents of the plankton in the highland lakes

of Tasmania, though this is the first record of its occurrence in Australasia. This

genus ranges all over the Northern Hemisphere, but is apparently absent from the tropics

of the Old World. In America, however, it follows the route of the Andes right down

into Patagonia, and, as we have said, turns up again in the extreme southern corner of

Australasia. It may be objected that it is not legitimate to use an animal of this kind

as an argument in a discussion on geographical distribution, because it is easily dis-

tributed by means of birds transporting its resting-eggs to great distances. We must

remark, however, that Bosmina only inhabits large pieces of water not liable to dry up,

and that its propagation is chiefly parthenogenetic, the resting-eggs being produced in

any quantities only once a year, and then falling to the bottom of the lake or tarn out of

reach of any water-bird. Moreover, it does not appear that even those Cladocera which

inhabit small ponds and puddles liable to desiccation are distributed haphazard all over

the world by wind or water-birds. It is true that practically all the genera are cosmo-

politan, but the fact that each country has for the most part its well-marked and distinet

specific forms shows clearly that the wide distribution of the genera has taken place

by a gradual extension of range, facilitated no doubt by their special adaptation for

transport.

In the case of the Anaspidacea, which are at the present time represented by three

distinct forms (Anaspides, Paranaspides, and Koonunga—the first two being confined to

the highlands of Tasmania and the last to Western Victoria), the fact that in Permian

and Carboniferous times closely related marine forms (Gampsonyx, Paleocaris, &e.)

existed in the Northern Hemisphere suggests that these animals have followed a similar

route to Gammarus and Bosmina and have reached temperate Australia through

Antarctica.

The Phreatoicidea, constituting an isolated suborder of Isopods, are at the present

time confined to the freshwaters of temperate Australia and New Zealand, and we know

nothing about their geological history. They are, however, so characteristically a part

of the temperate Australian fauna, for the most part being inhabitants, like the Anaspi-

dacea, of alpine stations, that they probably also belong to the same element of Antarctic

derivation as all the above-mentioned Crustacea. Leaving aside the small Entomostraca

of world-wide distribution, the only freshwater Crustacean in Tasmania which has

clearly been derived from the Asiatic tropics is the prawn Yiphocaris compressa, which

at the present day ranges into Queensland and whose near allies extend through the

East Indies into China.

The distribution of the two common genera of Phyllopods, Lepidurus and Apus, is of

interest. Both these genera occur in the Northern Hemisphere, and of the two Lepidurus

is the more characteristic of cold alpine stations. Now Lepidurus has a representative

in temperate South America (ZL. patagonicus), and another in Tasmania and the

temperate parts of Australia (Z. viridis), but it is entirely absent from central and

tropical Australia, where it is replaced by Apus. The latter genus, on the other hand,

is not known in the temperate parts of Australia or 8. America. It would appear

FRESHWATER CRUSTACEA OF TASMANIA. 69

therefore that Zepidurus has reached Australia by way of S. America and Antarctica,

while Apus entered by way of the Asiatic tropics.

The evidence of an Antarctic connection between New Zealand, Southern Australia,

and South America, derived from a consideration of the freshwater Crustacea of Tasmania,

is thus particularly cogent, because we are dealing with a group of animals whose distri-

bution is closely dependent on temperature, and unless we are to suppose that tropical

Asia and Australia have in the not very distant past possessed a totally different climate

and physical character from their present condition, it is impossible to conceive that these

essentially temperate and for the most part alpine creatures have reached their present

isolated position in Tasmania by this route.

And when we take into consideration the fact that the freshwater fish of Tasmania

(Galaxias, Prototroctes, and Aphritis), the Mollusca for the most part, and the most

typical of the Alpine trees (e. g. the two species of Fagus, F. Cunninghamii and F. Gunnii)

have their closest allies in one or more of the countries of the temperate Southern

Hemisphere, we are forced back on the existence in the past of a land-connection,

probably, as Mr. C. Hedley originally suggested (Ann. Mag. Nat. Hist. (6) xvii. 1896,

p- 113), by means of rays of land passing southwards to meet an antarctic continent,

uniting these southern lands, which at the present time are separated by so vast and. so

deep stretches of ocean.

With the exception of the Isopods and Amphipods, it is not proposed here to give

a systematic description of the Malacostraca, as they have either been described else-

Family ATYID &.

Genus XIPHOCARIS.

XIPHOCARIS COMPRESSA, v. Mart.

This freshwater prawn is very abundant in those streams of Tasmania which are

discoloured by flowing over the sandstones, e.g. the Clyde and Jordan Rivers, and also in

some of the lakes with similar cloudy water, e.g. Lakes Sorell and Crescent and Tiberias

Swamp. It is a widely ranging species, extending into Victoria, New South Wales, and

Queensland. As no other prawn occurs in the freshwaters of Tasmania, it is unnecessary.

to give a description of this species.

Family PARASTACID2.

The classification of the Australian and Tasmanian Crayfishes is at present in the

greatest confusion, owing to the imperfect descriptions given by the earlier observers.

I must postpone a detailed account of the Tasmanian species until the large collection

now in my hands, from all parts of Australia, has been carefully examined.

Four distinct members of the family, and possibly more, exist in Tasmania.

There is, first of all, the very large Crayfish found in the cloudy streams and rivers of

the north coast, and on the west coast as far south as the Gordon River. This species

may attain to the weight of 8 or 9 lbs. and exceed in size our marine lobster. The

name Astacopsis franklinii (Gray) should be reserved for this species. There is another

much smaller, but closely allied, species, to which the name <A. tasmanicus (Erichson)

will be applied. ‘This species is never, when adult, more than six or seven inches long,

and it inhabits the small mountain-streams of Southern Tasmania, e. g. the streams

round the base of Mt. Wellington. It is distinguished from the large species by a

number of small constant characters: e. g., the pincers of the great chela in A. franklinii

have two enlarged tubercles on their internal edges, while there is only one in

A. tasmanicus ; the wrist in 4. franklinii has only two spines on its upper internal border,

while A. ¢tasmanicus has three or more; the branchiostegites in 4. tasmanicus are

uniformly rugose, while those of A. franklinii are smooth with a few enlarged rounded

tubercles. :

The Land-Crayfish, known locally as the Land-Crab, occurs all over the northern and

western parts of Tasmania, from sea-level to the tops of the mountains at 4000 ft., on

marshy plains or in damp situations in the “ myrtle” forests (Fagus Cunninghamii, Hook.)

of the West Coast. It belongs to Erichson’s species Engeus cunicularis.

There also appears to be a very interesting form in Tasmania intermediate both in

structure and habits between Hngeus and Astacopsis. I did not myself meet with this

form, but Prof, Haswell, Sydney, has given me some which were collected in the western

Lake District of Tasmania, and there are some very similar specimens from Victoria in

the large collection entrusted to me by Professor Spencer of Melbourne.

ANASPIDES TASMANIA.

This species occurs in isolated pools and in the pools of the North-West Bay River on

the top of Mt. Wellington, in the tarns on the top of the Harz Mountains and on

Mt. Field, and in the tarns on Mt. Read, and probably other mountains on the West

PARANASPIDES LACUSTRIS.

This species occurs only, so far as is known, in the littoral region of the Great Lake ;

the waters of this lake are never very clear, but always discoloured to a certain extent

with sand. P. lacustris is distinguished by its pale green transparent colour, finely

powdered with black dots, by itssharply bent body, and by the great size of the antennal

scales and tail-fan.

Family PHREATOICID&.

Genus PHREATOICUS.

Chilton, Trans. Linn. Soc. Lond. ser. 2, Zool. vol. vi. (1894) p. 185.

Remarks.—Besides the New Zealand species P. typicus and assimilis, P. australis

has been described (Chilton, Records of the Australian Museum, 1 & 2, 1890-95, p. 149)

from Mt. Kosciusko in Victoria and also recorded by Thomson (Proc. Roy. Soc. Tasmania,

1892, p. 76) from Mt. Wellington. Besides this a blind species, P. shephardi, has been

described by Sayce (Proc. Roy. Soc. Victoria, vol. xiii. 1900, p. 25) from Victoria.

The other genera are Phreatoicoides (Sayce, Proc. Roy. Soc. Victoria, vol. xii. 1900,

p- 122) from Gippsland, Hypsometopus (Sayce, loc. cit. vol. xiv. p. 218) from burrows of

the land-crayfish Hng@eus in Tasmania, and Phreatoicopsis (Spencer & Hall, loc. cit.

vol. xix. 1896, p. 14), a large terrestrial form from Gippsland.

As very little has been recorded of the habits or internal structure of these animals,

the following notes may be given :—Their movements are exceedingly sluggish, so that

when alive they are easily distinguished from the rapidly moving Amphipods, which in

external structure they so closely resemble. They appear to be entirely vegetable-

feeders, and subsist by passing a great quantity of vegetable mud, &e., through their

intestine, much in the same manner as an earthworm. ‘This also appears to be the

habit in the land-form Phreatoicopsis. In specimens of this form which I dissected I

first noticed that the gut, which was full of earth, was provided with a highly developed

typhlosole or double fold, running its whole length, and quite unlike any structure met

with elsewhere among the Crustacea. The anterior portion of the gut, slit open along

the dorsal surface and displaying the gastric mill and the beginning of the double

typhlosole, is shown on PI. 12. fig. 13, while a diagrammatic transverse section (Pl. 12.

fig. 12) shows the relation of the typhlosole to the wall of the alimentary canal. It is

evident that the vegetable mould, after being pounded up by the action of the ridges and

pads of the gastric mill, is passed underneath the typhlosolar flaps, which enormously

increase the area for absorption. A similar typhlosole was found to exist in the various

species of Phreatoicus, so that it is probably a characteristic of the whole suborder.

The alimentary canal is supplied with four hepatic czeca, which lie ventrally and open

at the base of the gastric mill.

A pair of very large maxillary glands are present.

The above points in the internal anatomy of the Phreatoicidea confirm the opinion

that they constitute a rather isolated suborder of the Isopoda, but does not lend support

to the view that they are related to the Amphipoda.

PHREATOICUS AUSTRALIS, Chilton, Records of the Australian Museum, 1 & 2, 1890-95,

pd495) (Pl 12. fe.)

The thoracic segments are not much sculptured or tuberculated, and carry very few

spines dorsally.

The head is as long as the two following segments.

The second antenna has the peduncle and flagellum rather short, and the former has

the margin of only the first two joints serrated (Pl. 12. fig. 9).

The telson and uropod have the forms shown in Pl. 12. fig. 2.

The colour is uniformly black and the length about 10 mm. Occasionally yellowish

specimens occur.

Occurrence. Recorded by Chilton from Mt. Kosciusko and Thomson from

Mt. Wellington. J have taken it in the small pools on the top of Mt. Wellington, in a

small stream at sea-level at Huntingfields, and in a lagoon at sea-level on Bruni Island.

Also in Yule’s Lake on the top of Ben Lomond and in the littoral region of the Great

Lake. The uropod differs slightly in the arrangement of the spines from the various

localities. The Ben Lomond (PI. 12. fig. 3), Great Lake (PI. 12. fig. 2), and the specimens

from the other localities (Pl. 12. fig. 4) form three different varieties.

PHREATOICUS SPINOSUS, sp. n. (Pl. 12. fig. 7.)

The head is shorter than the two following segments.

The body is markedly sculptured, and the thoracic segments bear two distinct

tubercular ridges dorsally with a concavity between them; the abdominal segments are

also ridged. All the segments are furnished very richly with long and conspicuous

spines dorsally, and the legs are also covered with long spines.

The second antenna (PI. 12. fig. 11) has the peduncle and flagellum very pene only

‘the first two joints of the peduncle having a serrated margin.

The telson ends in a long projection and the uropods are also very long (PI. 12. fig. 8).

The colour is blackish grey, with the extremities of the antennze and often of the limbs

bright orange.

Length up to 25 mm., but also adult at 15 mm.

Occurrence. Avoong weeds in the littoral region of the Great Lake.

FRESHWATER CRUSTACEA OF TASMANTA, 73

(Pl. 12. fig. 5.)

The head is shorter than the two following segments.

The body is markedly sculptured as in P. spinosus, but is not spinous, only a few

inconspicuous setze being present on the dorsum. The segments of the pleon are rather

broader than usual.

The second antennee are not very long; the whole of the peduncle and most of the

flagellum has a serrated margin (Pl. 12. fig. 10).

The telson has the form shown in PI. 12. fig. 6; the uropods do not project much beyond

the end of the telson and are poorly furnished with stout spines.

The colour is straw-yellow.

Length 15 mm.

Occurrence. In the deeper littoral of the Great Lake, where the bottom is chiefly

composed of a fine yellowish mud.

NEONIPHARGUS NIGER, sp. 0.

Head as long as two following segments. Eyes small, oval.

First antennz very long; the third segment of peduncle not so long as second;

bunches of slender sete ; secondary appendage with three short joints, the whole not as

long as first segment of flagellum (Pl. 15. fig. 1).

Length 8 mm.

Colour. Black.

Occurrence. Under stones in Lake Perry, Harz Mountains.

NEONIPHARGUS MONTANUS, Thomson, Proc. Roy. Soc. Tasmania, 1892 (1898), p. 70.

This species agrees very closely with WV. yuli, but differs in the absence of a rudimentary

terminal joint to uropod 8, in the fewer sete on the lobes of the telson, and in the less

spinose pereiopods.

I have been unable to examine this species closely, as the tube in which I had collected

some was broken.

From pools on the top of Mt. Wellington.

NEONIPHARGUS SPENCERI.

Unimelita spenceri, Sayce, Proc. Roy. Soe. Victoria, vol. xiii. (1900) p. 238.

This species agrees most closely with NV. ¢asmanicus from the Great Lake. It differs,

however, in a number of essential points—e. g., shape of telson, great length of

uropod 3, shortness of secondary appendage, &c.

From Lake Petrarch.

Genus GAMMARUS, Fabr.

Remarks.—The genus Gammarus as restricted by Stebbing (Das Tierreich, Crustacea,

Amphipoda Gammaridea, 1906) is confined chiefly to the freshwaters of the Northern

Hemisphere. It is absent from the tropics and the Southern Hemisphere. Sayce

has, however, described two species, G. australis and G. haasei, from Victoria,

FRESHWATER CRUSTACEA OF TASMANIA. Ve

which clearly belong to this genus, and he has suggested that Niphargus mortoni

described by Thomson also belongs to Gammarus.

Lhe two species described below, G. ripensis and antipodeus, are evidently closely

allied to Thomson’s WV. mortonz, and a careful examination of their characters has shown

that they are exactly intermediate in structure between the genera Neoniphargus and

Gammarus.

Thus the telson (Pl. 14. figs. 19 & 25) cleft to the base and the form of the gnathopods

(Pl. 14. figs. 20 & 26) are Gammarid, while the three-jointed secondary appendage of

the 1st antenne (Pl. 14. figs. 17 & 23), the inner ramus of uropod 8 (PI. 14. fig. 18), the

condition of the inner plate of the mavilla (Pl. 14. fig. 22) are very close to Neoniphargus,

but with distinct Gammarid tendencies. With regard to the first maxilla especially, it

is to be noted that of G. antipodeus (Pl. 14. fig. 22) is exactly intermediate between that

of Neoniphargus (Pl. 18. fig. 5) and Gammarus (PI. 14. fig. 27). It is, in fact, very

difficult to say to which genus they are more nearly allied, and it would perhaps be

permissible to erect a new genus to receive these three species. The occurrence of these

intermediate forms between Gammarus and Neoniphargus certainly suggests that Neo-

niphargus has been derived independently from Gammarus in the Southern Hemisphere

and that it is not genetically related to the Miphargus of the Northern Hemisphere. In

this case, the species described by Sayce as Niphargus pulchellus from Victoria (Proc.

Roy. Soc. Victoria, 1899, vol. xii.) should not be placed in Miphargus, with which, indeed,

it does not closely agree, but in a separate genus. ‘The resemblance of this species and

of the numerous species of Neoniphargus to the European Niphargus must then be looked

upon as a remarkable case of convergence.

GAMMARUS MORTONI.

Niphargus mortoni, Thomson, Proc. Roy. Soc. Tasmania, 1892 (1893), p. 68.

This species is evidently closely related to the two described below, but probably not

identical with either. Thomson’s figures do not give quite the requisite details. The

form of the telson is, however, different to that in the two following species.

Occurrence. In a small stream above Franklin on the Huon River and on

Mt. Wellington.

GAMMARUS RIPENSIS, Sp. n.

The coxal plates of the fourth pair-are normally quadrate in shape. The eyes are

oval.

The first antennze have the peduncle of three subequal joints, clothed with a continuous

row of fairly long sete. ‘The secondary appendage consists of three joints (Pl. 14.

fig. 23).

The gnathopods have the two penultimate joints normal in shape, longer than broad,

with the inner surface provided with rows of stout bristles (Pl. 14. fig. 20).

The pereiopods are armed with fairly numerous and long sete; the terminal joint

with its claw is slender and rather elongated.

The third pair of uropods projects distinctly behind the outer two pairs.

SECOND SERTES.—ZOOLOGY, VOL. XI. 11

78 MR. GEOFFREY WATKIN SMITH ON THE

The outer ramus of uropod 3 has a minute terminal joint, and there are three groups

of spines, with one plumose seta. The inner ramus is small and scale-like with a single

terminal seta (Pl. 14. tig. 24).

The telson is cleft to the base; the lobes are slightly concave posteriorly and carry

two stout spines (Pl. 14. fig. 25).

The segments of the abdomen are very spinous.

Length 13 mm.

Colour. Dark greenish brown.

Occurrence. Among weed and under stones in the littoral region of the Great Lake.

GAMMARUS ANTIPODEUS.

The coxal plates of the fourth pair have the hind margin produced to form a triangular

lobe (PI. 14. fig. 21). The eyes are narrow and elongately oval.

The first antenne have the third joint of the peduncle shorter than the second ; clothed

with a continuous row of short sete. The secondary appendage is of three joints

(Pl. 14, fig. 17):

The gnathopods are similar to those of G. ripensis, but the distal outline of the carpo-

podite is more sinuous (PI. 14. fig. 20).

The pereiopods are feebly armed with very short sete; the terminal joint with its

claw is stout and not long.

The third pair of uropods project distinctly behind the other two pairs.

The outer ramus of uropod 3 is without a terminal joint, and there are more than three

groups of stout spines with several plumose setz. The inner ramus is rather large and

has four terminal setze (Pl. 14. fig. 18).

The telson is cleft to the base; the lobes are concave posteriorly and carry a single

stout spine and several small ones (Pl. 14. fig. 19).

The segments of the abdomen are quite smooth.

Length 20 mm.

Colour. Dark greenish brown.

Occurrence. In Mole Creek, just after issuing from a number of large limestone caves.

In the caves themselves, which are quite dark, a colourless specimen was found with

very much reduced eyes, and more numerous plumose sete on uropod 3. Otherwise it

agrees exactly with the species described.

GAMMARUS AUSTRALIS, Sayce, Proc. Roy. Soe. Victoria, vol. xiii. (1901) p. 233, & ibid.

This species shows more clearly than the above-described the true characteristics of

the genus Gammarus. ‘Thus, besides the cleft telson and the broad internal plate of the

Ist maxilla (Pl. 14. fig. 27), there are distinct sexual differences in the gnathopods, the

imner ramus of uropod 3 is quite long, and the secondary appendage of the first antenna

has six or seven joints.

Genus CHILTONIA.

Stebbing, Trans. Linn. Soc. Lond. ser. 2, Zool. vol. vii. (1899) p. 408.

The type species of this genus was described as Hyalella mihiwaka by Dr. Chilton

from New Zealand. Subsequently Sayce described H. australis from numerous localities

in Victoria and from Lake Petrarch in Tasmania. The genus Hyalella is otherwise

confined to8. America. Stebbing pointed out some differences between the New Zealand

species and the 8. Anrerican Hyalella and proposed a new genus Chiltonia. The chief

differences between Hyalella and Chiltonia are the presence in the former of a minute

rudimentary palp to the first maxillz, and also the presence of a lobe on the wrist of the

second gnathopoda in the male. Evidently the two genera are closely allied, and can

hardly have been independently derived.

CHILTONIA AUSTRALIS (Sayce).

This species can be at once distinguished from the other freshwater Gammarids in

Tasmania by the short first antenne and the entire absence of a secondary appendage, by

the pronounced sexual difference in the gnathopods (the second pair in the male being

greatly enlarged), by the absence of a palp on the first maxille, and by the undivided

telson. The colour is pale green and the length about 8 mm.

Occurrence. Southern Victoria (Sayce); in Tasmania the localities are Lake St. Clair,

the Great Lake, Lagoons on Bruni Island, Clyde River near Bothwell; in fact, it is the

most widely distributed species in Tasmania.

This species of land-hopper is widely distributed in the highlands of Tasmania, being

found under logs and leaves in the forests on Mt. Wellington and in very great abundance

in the beech-forests on the mountains of the West Coast. It also occurs in Victoria

The first antennz carry very short terminal setze, and a fairly long single seta on a

ridge some distance away from the apex.

The distal joint of the second antenne bears only two compound plumose sete

(Pl. 15. fig. 15).

The anal claws are long and are not furnished with any small spines; behind the

claws the telson bears laterally five large spines decreasing in size anteriorly. Between

the anal claws and the two plumose sete on the back, the hind end of the body is

regularly arched without any distinct angulation or sinuosity (Pl. 15. fig. 14).

Length 1 mm.

Colour. Green.

Occurrence. In the plankton of Lake St. Clair. No males were observed.

FRESHWATER CRUSTACEA OF TASMANIA. 81

CERIODAPHNIA PLANIFRONS, sp. n. (PI. 15. fig. 17.)

This small species has the carapace more elongated than C. hakea, and has the

posterior angle of the carapace clearly marked and almost forming a distinct spine.

The constriction between the thorax and the head is not very clearly marked. The

head is not furnished with any spines, and its outline is regularly curved without any

distinct sinuosity ; nor is there any spine or turgescence in front of the insertion of the

first antennee.

The first antennze have short terminal sete, and one rather long seta on a ridge close

to the apex.

The ocellus is clearly marked.

The second antennz are similar to those of C. hakea. The anal claws are long and

unarmed, and there are five lateral spines behind them. ‘These spines nearly reach to a

fairly distinct angle, which is not marked in (. hakea.

Length ‘9 mm.

Colour. Green.

Occurrence. In the plankton of Lake Sorell. No males observed.

Genus SrmocepHauus (Scheedler).

Four species have been described from Australia by Sars (Archiv for Math. og

Naturvid. vol. xviii. (1896); and Forhand. Vidensk. Selsk. Christiania, 1885), agreeing

fairly closely with northern members of the genus. The species described below does

not offer any marked characters.

SIMOCEPHALUS DULVERTONENSIS, sp. n. (PI. 15. figs. 5-7.)

The carapace is rather quadrate in form; the posterior angle is rounded and dorsal in

position, with its margin carrying a few short spines. The ventral margin is uniformly

clothed with setz, which towards the posterior end are stout and spiniform. The under

surface of the head is greatly elongated, and there is a small projection just in front of

the insertion of the first antenne.

The first antenne have their sides hollowed out; they carry about ten hollow sete,

and a single small seta on a projection about halfway down the stem (Pl. 15. fig. 6).

The second antenne have the structure characteristic of the genus; the tops of the

segments are very distinctly serrated.

The anal claws are long and without any additional spines at their base. Behind the

claws are about eight strong spines, the anterior ones being very small. The angle

behind these spines is fairly prominent and carries several rows of small bristles (Pl. 15.

fig. 7). The hind part of the body between this angle and the two dorsal sete is also

slightly angular.

Length 2 mm.

Colour. Green.

Occurrence. Among thick weed in Lake Dulverton. No males. Also among weed

in Great Lake.

82 MR. GEOFFREY WATKIN SMITH ON THE

SIMOCEPHALUS AUSTRALIENSIS, Dana, United States Exploring Expedition, Crustacea,

ii. p. 1271; also Sars, Forhandlinger, Christiania, 1888, p. 15.

This species can be readily distinguished from the foregoing by the distinct projection

on the underside of the head just in front of the insertion of the first antennze (Pl. 15,

fig. 8), and also by the form of the telson, which has the anal claws armed with a

conspicuous row of spines at their bases (PI. 15. fig. 9). There is a good deal of variation

in the shape of the hind part of the carapace, the posterior angle being sometimes

pronounced and sometimes almost absent.

The species occurs in quite small puddles and ponds, and is evidently universally

distributed in Tasmania. Dana and Sars report it from near Sydney.

Genus Dapnnta, O. F. Miller.

Darunta OARTNATA, King, Proc. Roy. Soc. Tasmania, 1853, p. 253.

This species was found by Mr. King in the neighbourhood of Sydney.

I found some very large specimens, measuring 8 millimetres in length, in a few cupfuls

of water in a cart-rut near Plenty, Tasmania. ‘These specimens were among the tubes

in my collection that were destroyed, so that I cannot give a full description of them.

They agree, however, with King’s figure of D. carinata, variety ©, in having the spine

at the back of the carapace very short.

Family BosmiIn1p™ (Sars).

Genus Bosmina (Baird).

The three species described below, which are the only Bosminide hitherto found in

Australasia, are closely related to the common northern B. longirostris. They possibly

only represent varieties of one species.

BosMINA ROTUNDA, sp. n. (PI. 15. fig. 18.)

Female.—Form of the carapace very round, with the posterior angle not distinetly

marked, <A seta is present on each valve close to the posterior spine. ‘There is a

slight projection where the forehead passes into the first antenne.

The first antennx are long, slightly curved, and with about eleven joints below the

antennal spine and sensory sete.

The second antenne are short and do not project as far as the anterior angles of the

valves of the carapace ; their structure is normal.

The anal claws are long, and carry about four small spines near their base; the telsonic

angle is furnished with about three rows of small bristles.

Length ‘9 mm.

Colour. Green.

Occurrence. In the plankton of Lake St. Clair. Males were not observed.

FRESHWATER CRUSTACEA OF TASMANTA. 83

BOsMINA BREVIROSTRIS, sp. n. (PI. 16, fig. 1.)

Female.—The carapace is more elongated than in B. rotunda and the posterior angle

is distinctly marked. A seta is present on each valve close to the posterior spine.

There is a slight projection where the forehead passes into the first antennee.

The first antennze are short, slightly curved, and with about 8 joints below the

antennal spine and sensory sete.

The second antennz are short and do not project as far as the anterior angle of the

valves of the carapace.

The anal claws are rather short and carry about six small spines, which extend nearly

to the tip of the claws.

Length ‘5 mm.

Colour. Green.

Occurrence. In the plankton of the Great Lake. No males were observed.

BosMInA sorELLI. (PI. 16. fig. 2.)

Female.—This very small species has the carapace elongated and sloping rather

‘suddenly to the posterior angle from the dorsal surface; the angle is well marked.

There is practically no projection where the forehead passes into the first antenn.

The first antennze are long with about 11 joints below the antennal spine and sensory

sete.

The second antennz are short and do not project as far as the anterior angle of the

valves of the carapace.

The anal claws are long, with about 4 spines near their base.

Length °35 mm.

Colour. Green.

Occurrence. In the plankton of Lake Sorell. No males were observed.

Family LYNCODAPHNIDA.

Genus Macrorurix (Baird).

Sars (Forhand. Christiania, 1885) has described JZ. spinosa from Australia.

Macrorurrx BURSTALIS, sp. n. (PI. 16, fig. 3.)

The carapace is oval in shape, with the posterior angle rounded and situated rather

dorsally.

The ventral margin of the carapace is fringed with exceedingly long and conspicuous

sete.

There is practically no constriction between head and thorax.

The first antennz are not dilated at the end, are tipped with a few very long sete,

and carry about 8 short spines on their stems interiorly.

The second antenne have the normal structure ; the compound setz are very long

and all subequal in length.

The anal claws are rather small and simple, without spines; behind them is a

continuous row of bristles fringing the whole posterior region of the body; posteriorly

in the neighbourhood of the dorsal setze these bristles become strong and spiniform.

There is a distinct indentation in the contour of the hind region of the body.

The dorsal sete are unique in structure, in that they end in a bunch of simple non-

plumose bristles.

Length ‘4 mm.

Colour. Green.

Occurrence. Among weed in Lake Dulverton. No males observed.

Family LynNcrip#.

Genus ALONELLA (Sars).

This genus and the related Alona and Dunhevedia appear to be abundantly represented

in Southern Australian waters.

ALONELLA NASUTA, Sp. n. (PI. 16. fig. 4.)

Form of the carapace is regularly oval without any marked angles. The usual

striations and ventral fringe of setze are present.

The head is drawn out into an exceedingly long and tapering nose, which projects far

beyond the end of the first antenne.

The first and second antennze are normal in structure and do not call for any special

remark.

The anal spines are long and furnished at the base with one strong spine and several

bristles. On the telson are four stout short spines, and then follow about five groups of

bristles. Beyond these bristles comes a marked concavity, and the margin is continued

rather sinuously to the dorsal setze (Pl. 16. fig. 5).

Length ‘5 mm.

Colour. Yellow.

Occurrence. Among thick weed in Lake Dulverton. No males observed.

ALONELLA PROPINQUA, sp. n. (PI. 16. fig. 6.)

The carapace is rather square-shaped, but without any distinctly marked angles. It

is fringed ventrally with sete, and the strize on the carapace are densely broken up into

roughly quadrangular blocks.

The head is drawn out into a moderately long proboscis; but both the first and

~ second antennee project nearly as far as the proboscis, thus differing from 4.-nasuta.

The appendages do not offer any characters of specific importance.

The anal claws are long and furnished each with a single strong spine at its base.

The telson rises abruptly above the anal claws and is furnished with a row of 9 lateral

fairly stout spines, behind which are one or two very small bristles of insignificant

appearance. Between the end of the spine-row and the dorsal setz the back is smooth

and rises to a prominence about midway (Pl. 16. fig. 7).

Length °35 mm.

Colour. Yellow.

Occurrence. Among thick weed in freshwater lagoon near Adventure Bay.

Termész. Fiizetek, Bd. xxiv. p. 1, and Bd. xxv. pp. 101, 436; Mrdzek, Ergeb. Hamburg.

Magalh. Sammel. Lief. 6 (1902).

This genus hitherto consists of several species from Patagonia and temperate

8. America, B. triarticulata, Thomson, from New Zealand, B. robusta, Sars (Archiv for

Math. og Naturvid. Christiania, xviii.), and B. minuta, Sars (loc. cit.), from 8. Australia.

It differs from Déiaptomus in several quite constant characters, especially in the con-

formation of the last pair of limbs in the male. The antennze, mouth-parts, and other

limbs are built very much on the Diaptomus plan.

The genus appears to be entirely confined to the temperate Southern Hemisphere.

BOECKELLA INSIGNIs, sp. n. (Pl. 17. figs. 4-12.)

Female.—Vhe anterior portion of the body is cylindrical; the head and first segment

fused with it are equal to the succeeding anterior segments. The fifth segment is small,

with inconspicuous lateral prolongations which do not project far over the abdominal

segments.

The first abdominal segment is not swollen in the middle. The abdomen consists of

3 segments.

The first antenna consists of 24 joints. The second antenna, mandible, maxilla, and

first maxillipede have the form shown in PI. 17. figs. 7-10.

The last leg has the form shown in Pl. 17. fig. 11. It closely resembles that of

B. robusta, Sars.

The uropods bear 5 sete each, exceeding in length the uropods and the last two

abdominal segments (Pl. 17. fig. 5).

Length 2 mm.

Colowr. Green.

Male.—The male is a good deal smaller and has a narrower body. The fifth segment

has very small lateral projections. The abdomen consists of 5 distinct segments, not

counting the uropods (Pl. 17. fig. 5). The last pair of legs have the form shown in

Pl. 17. fig. 12. The right limb has the external ramus biarticulate, with rather a short

claw. The left limb has the external ramus uniarticulate, with a longer claw. They

resemble closely those of the male B. robusta, Sars.

The first antenna, which is distinctly geniculated, has 23 joints (Pl. 17. fig. 6).

Occurrence. Among weed in Lake Dulverton.

BoECKELLA LONGISETOSA, sp. n. (PI. 17. figs. 13-17.)

Female.—The head and first segment fused with it are shorter than succeeding anterior

segments. The fifth segment is fairly large, with fairly conspicuous lateral projections

which are distinctly bilobed, the outer lobe being spiniform, the inner rounded.

The first abdominal segment is rather swollen in the middle, and the abdomen consists

of 3 distinct segments, and also the uropods are rather distinctly segmented off, making

a fourth indistinct segment (Pl. 17. fig. 14).

The first antenna has 24 joints and the other limbs are similar to B. insignis.

The last leg is slender and feebly armed with setze, the internal ramus being tipped

terminally with 3 setze, but otherwise unarmed (PI. 17. fig. 16).

The uropods bear five compound setze, which are exceedingly long, equalling in length

the whole abdomen.

Length 1:5 mm.

Colour. Green.

Male.—Agyees with the male of B. insignis in having a five-segmented abdomen, a

more slender body, and no conspicuous projections on the fifth thoracic segment.

The first antenna, which is geniculated, has 22 joints (Pl. 17. fig. 15).

The fifth pair of limbs have the form shown in PI. 17. fig. 17. The internal ramus of

the right limb is two-jointed and bilobed at the end.

Occurrence. In the plankton of Lake St. Clair and Lake Sorell.

BoECKELLA RUBRA, sp. n. (PI. 18. figs. 1-5.)

Female.—Anterior portion of body narrow and cylindrical; the head and anterior

segment fused with it are about equal to the two succeeding segments.

The fifth segment.is large, with very conspicuous lateral projections, consisting of two

lobes, the external lobe being very long and spiniform and nearly as long as the first

abdominal segment, the internal lobe being smaller and rounded at the end. The first

abdominal segment is distinctly swoilen in the middle. The abdomen consists of three

segments.

The first antenna consists of 25 joints.

The last leg has the form shown in Pl. 18. fig. 3, from which it is seen that the sete

on the inner margin of the terminal joint of the external ramus are smaller than in

B. insignis, while the inner ramus is well armed with small sete and thus differs from

that of B. longisetosa.

The uropods have five simple setze apiece, about equal in length to the abdomen, thus

intermediate in length between those of B. insignis and B. longisetosa.

Length *7 mm.

Colour. Bright red.

Male.—Similar in form to the female, save that the lateral projections are absent on

the fifth segment, and the abdomen consists of 5 segments.

The first antenna, which is geniculated, has 28 joints, and the soars joint has a

very marked projection at its end (Pl. 18. fig. 2).

The fifth pair of legs have the form shown in Pl. 18. figs. 4&5. They differ from

the legs of the other species in the presence of an extra seta near the internal ramus

of the left limb, and in the presence of an extra seta on the claw of the external

ramus of the right limb.

Occurrence. This species occurs in vast swarms in the very old and deep tarns on the

Harz Mountains and on Mt. Read. It was never met with in small bodies of water or

at lower levels than about 3000 ft.

FRESHWATER CRUSTACEA OF TASMANIA. 87

BorcKELLA RoBuSTA, Sars, Archiv for Math. og Naturvid. xviii.

This large and handsome species was found in great abundance in several small

muddy ponds near Hobart (in a pond near the road at Sandy Bay and in a smal! pond

near the Cascade Brewery). Sars describes it from the neighbourhood of Sydney, so

that it is evidently a widely distributed form in Southern Australia. It can at once be

distinguished from the other species by its great size, by the comparative shortness of

the setze on the uropods, by its pale livid colour, and by the great length of the lateral

projections on the fifth segment.

Genus BRUNELLA, gen. n.

T have made this new genus of the Diaptomide to include a species found in a large

weedy freshwater lagoon near Adventure Bay, Bruni Island. It was present in great

quantities, but I did not meet with it anywhere else. It is impossible to include it in

any existing genus, as the structure of the thoracic limbs, and especially of the fifth pair

in the male, is quite peculiar. In its other characters (e. g. structure of antennze and

mouth-parts) it agrees very well with Diaptomus or Boeckella.

The diagnostic characters which concern the thoracic limbs are :—

1. The first thoracic limb has the external ramus biarticulate and the internal

ramus uniarticulate (Pl. 18. fig. 12).

2. The second, third, and fourth limbs have the external ramus triarticulate and

the internal ramus biarticulate (PI. 18. fig. 13).

3. The fifth thoracic limbs in the male differ on the right and left side. The right

limb has the external ramus 2-jointed, the last joint being spatulate and

carrying a very small terminal spine; the internal ramus of this limb is

2-jointed with an extra internal lobe. The left limb has the external ramus

3-jointed and ending in a greatly elongated claw; the interna] ramus of this

limb is 8-jointed (Pl. 18. figs. 15 & 16).

4, The fifth thoracic limbs of the female have the external ramus 3-jointed and the

internal ramus 2-jointed (Pl. 18. fig. 14).

This combination of characters is very peculiar. Thus the first two characters point

to affinities with Hurytemora, but the character no. 4 is unparalleled in any freshwater

Diaptomid, and one has to go to some marine genus (e. g. Centropages) for comparison.

Character 3 shows some agreement with Parabroteas michaelseni, described by Mrazek

from 8. America, but in its other characters it differs widely from that genus.

BRUNELLA TASMANICA, sp. n. (Pl. 18. figs. 6-16.)

Female.—The fore-body is narrow and cylindrical ; the head-segment tapers anteriorly

and has a slight depression laterally near the anterior end; this segment exceeds in

length the two following segments.

The fifth segment has small lateral projections, which are bilobed, the external lobe

being the larger and rounded at the end; the internal lobe is small and more acute.

The first abdominal segment is rather tumid ; the abdomen has three distinct segments,

not counting the segmented bases of the uropods.

12"

88 MR. GEOFFREY WATKIN SMITH ON THE

The uropods are long, equalling in length the first abdominal segment. They are

furnished each with four terminal plumose setze and one lateral; these setze are not

quite half as long again as the uropods.

The first antennz are long, equalling the length of the body; they consist of 27 joints.

The second antenne are similar in structure to those of Boeckella, and so are the

mandibular palps; the biting-edge of the mandible has the form shown in PI. 18. fig. 8.

The maxilla (Pl. 18. fig. 9) resembles that of Boeckella very closely, but has rather

fewer sete. The same applies to the first maxillipede (PI. 18. fig. 10).

The second maxillipede (PI. 18. fig. 11) closely resembles that of Boeckella, but the

internal lobe on the first joint is more prominent.

The first thoracic limb (Pl. 18. fig. 12) has the external ramus 2-jointed and the

internal ramus 1-jointed.

The third limb (which resembles closely the second and fourth) has the form shown

in Pl. 18. fig. 18. The external ramus is 3-jointed; the internal is 2-jointed. The

arrangement of the spines and setz is always constant as in the figure.

The fifth leg of the female (Pl. 18. fig. 14) has the external ramus 38-jointed and the

internal 2-jointed. The stout spine on the penultimate joint of the external ramus is

not plumose.

Length ‘7 mm.

Colour. Green. ;

Occurrence. In great numbers in a weedy freshwater lagoon near Adventure Bay,

Bruni Island.

Male.—The male differs from the female in having the first antenna normally

geniculated (Pl. 18. fig. 8) and in having five distinct segments in the abdomen.

The last pair of legs are very peculiar.

The right leg (PI. 18. fig. 16) has the external ramus 2-jointed ; the joints are flattened

and expanded, and there is a short stout spine on the terminal joint. Otherwise sete

are absent. The internal ramus is 2-jointed, the terminal joint bearing four long setze.

The other joint has a peculiar lobe upon it, and also another internal lobe springs from

its base.

The left leg (Pl. 18. fig. 15) has the external ramus 3-jointed, if we count the terminal

claw as a joint. There is a small spine at the top of the first joint and another small

spine on the base of the claw. The internal ramus is 8-jointed, the terminal joint

carrying four sete.

Family -CycLoPIpD#&.

Genus Cyctuops, O. F. Miller.

Besides one species, C. australis, King, characterised by Sars as peculiar to Australia

(Archiv for Math. og Naturvid. xviii.), the latter author reports (oc. cit.) several common

European species from small pools in and around Sydney (e. g., C. albidus, C. serrulatus,

C. affinis, &e.), This occurrence of species identical with those found in Europe is a little

suspicious, as nothing of the sort occurs among the other groups of Entomostraca,

almost all the species of Cladocera being peculiar. The species found in Tasmania,

although very closely related to European forms, are distinguishable as separate species.

FRESHWATER CRUSTACEA OF TASMANTA. 89

CYCLOPS ALBICANS, sp.n. (Pl. 16. figs. 8-12.)

The head-segment is broad and blunt; the succeeding segments have rounded edges,

which do not project laterally to any extent.

The uropods are about as long as the last two abdominal segments. They are

furnished each with four terminally placed sets, of which the innermost is much longer

than the outermost, but none of them are as long as the abdomen (Pl. 16. fig. 12).

The first antenna, which is as long as the first two segments of the cephalothorax,

consists of 17 joints. The terminal segments are without a row of spines or hyaline

membrane (Pl. 16. fig. 12).

The first swimming-leg (Pl. 16. fig. 9) has both branches consisting of three joints, and

so have the succeeding swimming-legs. The last two joints of the inner ramus of all

but the first pair have their internal margin serrated (Pl. 16. fig. 10).

The rudimentary fifth pair of limbs consist of two distinct joints ; the terminal joint

carries a plumose seta at its tip, and on its inner margin a serrated spine nearly as long

as the seta and situated on the inner margin near the tip. The basal joint carries a

fairly long seta on its external border (PI. 16. fig. 11).

Length ‘8 mm.

Colour. Very pale green or white.

Oceurrence. In the plankton of the Great Lake, and also in many small ponds, widely

distributed.

CYCLOPS DULVERTONENSIS, sp. n. (PI. 17. figs. 1-3.)

The head-segment is broad and blunt, but equal in length to the rest of the thorax.

The thoracic segments have their hinder edges distinctly produced and overlapping the

segments behind them.

The uropods are rather longer than the last two abdominal segments. They are

furnished each with four terminal sete, the innermost being very slightly longer than

the outermost, and the longest is as long or longer than the abdomen (PI. 17. fig. 3).

The first antenna (2), which consists of 12 joints, is about as long as the head-

segment. The terminal segments are without a row of spines or hyaline membrane.

The first swimming-leg has the inner ramus 2-jointed and the outer 3-jointed, the

basal joint being rudimentary. The succeeding legs have both rami 3-jointed, but

without any serration on the inner ramus.

The rudimentary fifth pair resemble closely that of the foregoing species.

Length °5 mm.

Colour. Dark green.

Occurrence. Among thick weed in Lake Dulverton.

V. On a Blind Prawn from the Sea of Galilee (Typhlocaris galilea, g. et sp. n.).

By W.T. Catman, D.Se., F.L.S. (Communicated by permission of the Trustees of

the British Museum.)

(Plate 19.)

Read Ist April, 1909.

THE British Museum has recently received from Mr. R. Grossmann, of Tiberias, two

specimens of a blind Crustacean, which differs in some remarkable characters from any

species at present known. The specimens, I understand, were not actually taken in the

Sea of Galilee itself, but from a small pond near the town of Tiberias communicating

with the lake and fed by a mineral spring. From the fact that the animal is without

any organs of sight (so far as can be ascertained by external examination), it seems most

probable that it is a species of subterranean habitat, brought to the surface by the

waters of the spring. It is much less probable that the specimens entered the pond

from the lake, although this is no doubt the origin of some small fish, taken along with

the prawns, which have been identified by my colleague Mr. C. Tate Regan as

Discognathus lamta, a common Syrian species.

Among the numerous species of subterranean Crustacea which have been described,

only a small number belong to Decapoda. The following list includes all the truly

subterranean species of which I can find record :—

AsTacipa&. PALEMONID.

Cambarus pellucidus (Tellkampf) *. Palemonetes antrorum, Benedict §.

5 hamulatus, Cope & Packard *. ” eigenmanni, Hay ||.

FA setosus, Faxon +. ATYID.

A PCa Oe ea Troglocaris schmidtti, Dormitzer 4].

Palemomas ganteri, Hay **.

From this list have been omitted species like those of Huryrhynchus and some of the

species of Cambarus, which, while known or suspected to have a subterranean habitat,

have well-developed eyes, and may therefore be assumed sometimes to frequent the

surface-waters.

94, DR. W. T. CALMAN ON A

The blind marine cavernicolous species Munidopsis polymorpha, which I have discussed

elsewhere *, belongs to a somewhat different category as regards habitat.

According to Barrois , the only Decapod Crustacea recorded from the Sea of Galilee

are the Crab Telphusa fluviatilis (or more correctly, according to Miss Rathbun,

Potamon potamios) and the Atyid Hemicaridina (= Atyaéphyra) desmarestit.

Family PAL ZMONID 4.

TYPHLOCARIS, gen. nov.

Rostrum very short, flattened, without teeth. Carapace without antennal, hepatic,

or other spines, but with a longitudinal suture-line on each side. Outer flagellum of

antennule with a minute vestige of an inner branch. Mandible without a palp. Maxilla

with the distal endite undivided. Third maxilliped slender. Second perzeopeds much

larger than the first.

Type species, 7. galilea, sp. n.

The affinities and systematic place of the genus are discussed below.

TYPHLOCARIS GALILBA, sp.n. (Plate 19, figs. 1-13.)

Description of Male.—The carapace is smooth, its surface beset with very minute,

widely-scattered setze. In front it is produced in a minute triangular rostrum, flattened

and without any median keel, not extending beyond half the length of the ocular

peduncles. The orbital notch is defined below by a very slight convexity, but there are

no antennal, hepatic, or other teeth on the antero-lateral margin, and the antero-lateral

corner is broadly rounded. On each side the carapace is traversed by a longitudinal

suture-line or fine groove which runs, nearly straight, from a point opposite the base of

the antenna to the posterior margin. This suture has very nearly the position of the

linea thalassinica of certain Thalassinidea and of a similar line found in certain Penzeidze

(Parapeneus, Parapeneopsis), but I cannot find mention of any comparable structure

in the Caridea. ‘Towards its lower edge the carapace becomes membranous.

The abdomen has little of the ‘“‘ humped” form supposed to be characteristic of the

Caridea (Hukyphotes of Boas), but this feature is ill-defined in many other Caridea.

The pleural plates of the second somite are comparatively little expanded. The abdomen

is about the same width throughout its length, the sixth somite being broad and

depressed, hardly longer than the preceding somite, and much broader than long. The

~ telson (tig. 3) is longer by one-half than the sixth somite, and has a broadly triangular or

rounded tip, extending well beyond a pair of stout subapical spines and fringed with

spinules and sete ; there are two pairs of spinules on the upper surface.

The ocular peduncles (fig. 4) have the form of flattened scales, lying horizontally

and nearly touching each other in the middle line. On the upper surface of each are a

few setze. I could detect no trace of pigment or of ocular structure. The antennules

(fig. 2) have the stylocerite of the first segment blunt, closely applied to the side of the

segment, and not reaching its distal end. There are two long flagella (incomplete in both

specimens), the outer of which bears, at about the 52nd articulation in one specimen

and at the 25th in the other, a small biarticulate appendage (fig. 5); in other words, the

bifurcation of the outer flagellum is reduced toa minimum. I have been unable to detect

a statocyst in the basal segment of the antennule, but I am not confident that it is absent.

The antenna (fig. 2) has a flagellum longer than the body. The scale is about two-

thirds as broad as long, with the spine on the outer edge a little beyond the middle of

its length.

The mandibles (fig. 6) have well developed incisor and molar processes but no palp.

The maxillulz resemble those of Palemon. The maxille (fig. 7) have a very unusual

form; the proximal endite is obsolete (as in Palemon and many other Caridea) and the

distal endite is undivided, perhaps owing to the suppression of its proximal lobe.

The first maxilliped (fig. 8) has the lobe of the exopodite very large and pointed. The

second maxilliped (fig. 9) has a large epipodite, but the podobranchia appears to be

represented only by a small fleshy lobe on the anterior surface of the epipodite.

The third maxillipeds (fig. 10) are stout, and extend forwards well beyond the scales of

the antennze. The terminal segment is considerably longer than the penultimate. The

epipodite is represented by a small fleshy lobe which bears a group of yellow spines,

each very stout in the proximal half and tapering to a very slender tip. The first legs

are slender and, when extended forwards, the distal end of the merus reaches to the tip

of the antennal scale. The carpus is about equal to the merus and longer by one-half

than the chela. ‘The fingers are nearly twice as long as the palm.

The second legs (fig. 11) are large and subequal, and the merus extends beyond the

antennal scale. The carpus is about two-thirds as long as the merus. The palm is

inflated and slightly compressed laterally. In two of the chelee examined the palm is

about two-thirds as long as the fingers; the third, which may be abnormal, has the

immovable finger much shorter than the dactylus, which is about equal to the palm.

The fingers have a thin smooth cutting-edge, which forms a low tooth near the base of

each, and internally to this edge they have a series of widely-spaced teeth. The whole

limb is clothed with long and soft hairs.

The walking-legs are moderately stout. The dactyli are not toothed on the lower

(concave) edge, but have some stout spines on the upper surface. The pleopods (fig. 12)

have broad protopodites, on the posterior face of each of which, near the outer edge, is a

patch of stout yellow spines with filiform tips. Some of these spines (fig. 13) are irregu-

larly thickened or distorted. In the first pair of pleopods the endopodite is about half

as long as the exopodite, and has near its distal end on the inner side a clavate process

bearing a group of coupling-hooks. In the second pair the appendix masculina is

shorter than the appendix interna.

The uropods have both rami very broad and pointed, instead of rounded, distally. The

exopodite extends beyond the telson for half its length. The tooth on the outer margin

is about the middle of its length, and an oblique ridge runs inwards from it. The

96 DR. W. T. CALMAN ON A

endopodite possesses a suture-line running inwards from the outer margin in a corre-

sponding position, which looks as though it might be produced by the pressure of the

endopodite against the ridge of the exopodite. It is very rare for the endopod of the

uropods to show any trace of division into two segments by a suture-line, and I do not

know of any other case among the Caridea.

The branchial apparatus comprises five pleurobranchiz on the somites of the perzeopods,

an arthrobranchia on the third maxilliped, mastigobranchie (epipodites) on the first and

second maxillipeds and possibly also on the third (if this be the value of the spinose lobe

described above),.and a vestigial podobranch, represented by the simple lobe on the

epipodite of the second maxilliped. The branchial formula of Palemon differs from

this by the presence of a pleurobranchia above the third maxilliped and a distinct

podobranchia on the second.

The colour in life is stated to be white.

The characters of this species, as described above, show that it must be referred to

the family Paleemonide as defined by Borradaile *, but its exact position within the

family is not so easy to define. Borradaile includes as a subfamily of the Paleemonide,

the Pontoniine (formerly ranked as a distinct family), which are distinguished from most

of the Palemonine by having, among other characters, the rostrum often small and not

serrated, the bifurcation of the outer antennular flagellum reduced to a minimum,

and the mandible without a palp. In these points the present species agrees, but I do

not think that it can be regarded on that account as having any special affinities with

the exclusively marine Pontoniine. Asa matter of fact, the Palemonine already include

one genus, Huryrhynchus, Miers}, which agrees with that here described in the three

points of palpless mandibles, reduced and non-serrated rostrum, and freshwater (possibly

also subterranean) habitat. From Huryrhynchus and all the other Palemonine, however,

_ Typhlocaris differs not only in the suppression of all spines or teeth on the antero-lateral

margin of the carapace, but in other characters so important as to suggest that it may

be necessary to establish at least a new subfamily for its reception. Chief among these

characters are the presence of a pair of suture-lines on the carapace and the undivided

distal endite of the maxilla. I am not aware that these characters are paralleled in any

of the Caridea, and if, as seems possible, the suture of the carapace be homologous with

that of some Peneide and with the linea thalassinica, it may indicate that Typhlocaris

has been derived from some very ancient and primitive Caridean type. The resemblance

to the Thalassinidea in this character adds another to the indications already existing

(phyllobranchiz, appendix interna, larval development) that that group has some affinity

with the Caridea.

As indicated above, the only blind subterranean Paleemonidz known are two species

referred to Palemonetes occurring in Texas and Cuba respectively. Both have been

described only in a very summary fashion, but so far as their characters are known they

indicate no special affinity with the present species *.

According to information supplied by the collector, the species would appear to be

very rare. Repeated searches in the same locality over a period of two years only

resulted in the discovery of three specimens, one of which was afterwards lost by accident.

The other two specimens, which are males, are now in the British Museum, and form

the types of the species.

VI. On the Life-History of Chermes himalayensis, Steb., on the Spruce (Picea Morinda)

and Silver Fir (Abies Webbiana). By E. P. Sressine, F.L.S., F.Z.S., F.R.G.S.,

General Remarks.

ly April 1892 some galls found on Spruce trees (Picea Morinda) near Chakrata,

in the North-West Himalaya, were sent to the Indian Museum, Calcutta, by Mr. J. 8.

Gamble, F.R.S., the Director of the Imperial Forest School, Dehra Dun. The galls

were found to contain insects, but these latter were too immature at this period to

render identification possible. In July 1893 further specimens were sent from the same

locality by Mr. A. Smythies, Deputy Director of the School and late Conservator of

Forests, Central Provinces. Mr. Smythies procured some mature flies from the galls,

which were identified by the late Mr. Buckton as Chermes abietis, Kalt., the well-known

Spruce gall Aphis of Europe *.

In May 1901 and June and July 1902 the writer had an opportunity of visiting the

forest from which the above-mentioned specimens were sent, and neighbouring areas,

and made a study of this Ohermes. As is well known, Chermes viridis, Ratz., lives in

Europe upon the Spruce and Larch, series of agamic generations alternating between

these two trees, a sexual generation occurring but once a year in the autumn and then

always upon the Spruce, whilst another species, Chermes abietis, Kalt., lives only on

the Spruce.

In ‘Injurious Insects’ (1899), in quoting the discovery + of Chermes abietis in the

North-West Himalaya, a locality I had not at the time visited, I pointed out that it

would be interesting to know whether the Spruce grew pure in that locality, and if so

whether the insect existed on that tree alone.

My investigations during 1901 and 1902 ied me to the discovery that the Chermes

lived in a somewhat similar manner in the Himalaya to its European confrére,

C. abietis, but that in the absence of the Larch the second host plant was the Silver Fir

100 MR. E. P. STEBBING ON THE LIFE-HISTORY OF

(Abies Webbiana). I further came to the conclusion that the Himalayan species was

distinct from the European species Chermes viridis and C. abietis.

In two papers read before the Members of the Asiatic Society of Bengal in 1903 *,

I gave a brief account of the life-history of this Chermes, which I named Chermes abietis-

picee, on the Spruce and Silver Fir so far as it was then known to me.

I have now abandoned the specific name of abietis-picee in favour of himalayensis,

since the former would give rise to considerable confusion should Cholodkoysky’s

opinion that CO. abietis and C. picee are true species stand the test of careful

breeding-experiments.

The first paper treated of the mode of development of the alar appendages of the

Spruce form of the insect on its issue from the gall or pseudo-cone, whilst in the second

a general account was given of some of the stages of the parallel series passed by the

insect on the two trees, so far as was then known to me.

Whilst on furlough in England in 1904 I paid a visit to St. Petersburg, where I had

the pleasure of meeting Professor Cholodkovsky, the well-known eminent authority on

the genera Chermes, Lachnus, &c. I was thus afforded an opportunity of a full

discussion on this subject with the able Doctor. He fully confirmed my views as to

the Chermes of the Himalaya being an undescribed species, and expressed the greatest

interest in the marked differences in the life-history as then known.

Subsequent investigations—as yet, I am fully aware, by far from complete—have

enabled me to throw some further light on the existence of this remarkable inseet and

to correct some of the data given by me in my papers read before the Asiatic Society.

1 am also able, owing to the talent and assiduity of my wife, to supplement this

account with some valuable and interesting coloured plates drawn on the spot from

living specimens collected during a recent tour in Chamba State in the Himalaya.

The general Life- History of the Insect on the Spruce and Silver Fir,

Ohermes himalayensis, as the Indian species is named, closely resembles the Enropean

Chermes viridis, Ratz., in that the individuals of one generation may assume different

habits at different stages of their existence and so set up the phenomenon known as

“ parallel series.” Also the apterous forms of the insect are parthenogenetic, and, as we

shall see, several generations of these parthenogenetic females may be passed through

on one host plant. The insect lives on two host plants, the Spruce and Silver Fir, and

different stages in the life-history may be passed on either the one or other of the two.

~ Blochman and Dreyfus in Germany, Cholodkovsky in Russia, and, more recently,

E. R. Burdon, of Cambridge, in the ‘Proceedings of the Cambridge Philosophical Society,’

have made a series of most important and interesting observations on the habits of the

European Chermes—Cholodkoysky in his erudite ‘‘ Monographie der Coniferen-Lause ” +

treating of the subject in a most able manner. Burdon’s interesting papers * will be

alluded to later on.

As has been stated, the fact that the Himalayan form lives upon two host-plants was

unknown before 1901.

In order to present the somewhat complicated stages of life passed through by this

insect in a form intelligible to the reader, I propose to give a brief description of the

various generations at present known to live upon the two trees and which give rise

to the parallel series.

To the generations of the European forms of Chermes the names I. FUNDATRICES,

Il. Atata#, III. Cononic1, IV. Sexupars, and V. SEXUALES have been given f, and I

propose, as far as possible, to retain these names in the following account.

In the early spring dead apterous females, “ stem-mothers” (Generation I. FunpDaA-

TRICES), are to be found upon the Spruce trees, these having most probably hibernated

through the winter. These females are merely shrivelled skins covering the masses of

eggs similar to those shown in Pl. 22. fig. 5. These dead females are found at the

base of small pinkish cone-shaped swellings which are galled buds, the females by

their sucking-operations having already caused the tissues of the stem in their close

neighbourhood to swell to an appreciable extent.

The larve hatching out from these eggs (Generation II. ALarm) feed at the base of

the young developing Spruce-needles, the part of the stem below and the needles

gradually swelling up and coalescing into a gall within which the young Aphids become

enclosed (ef. Pl. 20. fig. 1).

This gall resembles a small fir-cone and gradually increases in size, until during July

it opens by a contraction of its parts (cf. Pl. 21. fig. 1) and the now mature larve or

nymphs crawl out, moult their skins, and appear as winged insects.

A portion of these winged insects remain upon the Spruce, and lay the eggs from

which the stem-mothers of Generation I. Funparrices develop, whilst the others

fly to the Silver Fir, where they may be found upon the needles of the tree.

These are the MreranTEs-ALAT# of Burdon (see Table, p. 120). They there secrete a

cottony mass, which wholly or partially covers them, and lay eggs upon the needles.

Some of these eggs at least give rise to apterous parthenogenetic females, forming

Generation IIT. Cononict.

In the case of the Silver Firan examination of the branches of old trees and the masses

of saplings and poles in the early spring (May) will show minute white cottony specks

on the bark. These cottony masses at times may be seen thickly dotting the whole of

the bark of the stem of young saplings. The cottony masses contain a number of egg-

bunches, having the appearance under the lens of bunches of yellow and brown grapes,

as shown in Pl. 22, fig. 5. These eggs are those laid by the Cononicr. From these

eggs hatch out in the early spring little larvee, which crawl on to the newly-developed

young Silver Fir needles, insert their proboscides into the tissue of the under surface

and suck out the sap. These larvee reach full growth as apterous females, ExsuLEs

(fig. 2), in about three weeks, and these apterous females secrete cottony filaments,

under which they lay bunches of eggs on the needles, similar in appearance to the

spring ones, and die (figs. 3, 4). A portion of this generation is winged (fig. 7) and

would seem to represent a part of Burdon’s Generation IV. SexupaArm. From the

eggs laid on the Silver Fir needles hatch out in a few days small red grubs (see fig. 8),

which in their turn become full-grown and lay similar eggs (ExsuLES). <A portion of

these latter generations collect and feed down at the base of the needles and stem,

and cause the needles to contort and twist and curl inwards, forming a corkscrew

termination to the shoot towards the end of June (cf. Pl. 23. fig. 1). This corkscrew

would almost seem to be of the nature of a rudimentary gall structure, and thus this

species differs fundamentally from the European Chermes on the Larch, which forms

nothing in the shape of a gall-like structure. In this corkscrew both apterous (HXsULES)

and winged (SExuPAR#) insects are to be found. In the latter part of June and first

part of July the twisted-up needles are found to contain numerous eggs covered by the

usual dead mother skin and white cottony substance. These egg-masses are also to be

found on the twigs and stem of the tree and are very visible.

These eggs hatch out into grubs, which grow into minute apterous female insects

furnished with very long proboscides (Pl. 28. fig. 3). These insects, if not already there,

crawl down on to the bark of the branch, insert their proboscides down a crevice into the

bast and remain feeding there (¢f. Pl. 23. figs. 2, 3) throughout the rains, and, I think,

probably through a part of the winter, when they secrete the cottony material, lay eggs,

and die.

The winged forms (SEXUPAR#), or a portion of them, migrate to the Spruce, as I have

found living specimens on the old needles of the tree, as also dead insects stuck to the

needles. These insects presumably lay eggs upon the needles and give rise to the fifth

generation, the SexuaLEs. I have not found this generation on the Spruce. It would

presumably consist of wingless males and females, and give rise to the first generation,

the FUNDATRICES.

From what has been said, it thus becomes obvious that one important factor governs

the appearance and duration of the various generations passed through upon the Spruce

and Silver Fir, and that is the monsoon. The rains burst in the Outer Himalayan

Region we are considering early in July and bring to an end Generations I. and II. upon

the Spruce and Generation IV. on the Silver Fir.

With this brief review of the various phases of the life-history we will now proceed

to consider in fuller detail the life-stages passed respectively on the Spruce and

Silver Fir.

Nature of Attack.

The Chermes feeds on the sap of the twigs and new buds of the year, preventing the

development of the needles of the latter, which coalesce and form a small fir-cone-like

gall or pseudo-cone. These galls are at times exceedingly numerous on the trees and

not unlikely account for the scraggy appearance of many young trees, whose crown

104 MR. E. P. STEBBING ON THE LIFE-HISTORY OF

and branches have a thin and open appearance, and are seen to contain numerous old

and new galls upon them (ef. Pl. 20. fig. 1).

Distribution.

I have noted the presence of this insect in Jaunsar, Tehri Garhwal, Simla Hill States,

Bashahr, and Chamba States. It is doubtless distributed throughout the Western

Himalaya Region wherever the Spruce and Silver Fir are associated together in

mixture.

Description.

Stem-Mother (FUNDATRICES).—The skin of the dead insect is a dark brown madder to

black in colour. The insect is furnished with a very long proboscis, which is found fixed

in the tissues of the shoot.

Egg-Mass.—The egg-mass consists of a cluster of brown-yellow or brown-madder

eggs placed close together in such a manner as to resemble a rather open bunch of

grapes. This bunch is covered, and to some extent probably protected, by the dried skin

of the stem-mother.

Egg.—Small, ovate-elliptical, almost hen-egg-shaped, shining yellow to yellow-brown

or brown-madder in colour. Length 0°5 millim.

Young Larva from Spring Eggs (AuATm).—As seen under the microscope this is

small, a brown-maddey in colour; antennz consist of two large basal joints, followed

by a narrower longer one which is surmounted by a hair. The proboscis is short.

Three pairs of short legs are present, and the body is simply segmented and not as yet

much corrugated and crenulated.

Half-grown Larva.—Brown-madder in colour, the legs and antenne bright yellow.

No indications of wings are yet visible on the dorsal surface of the thorax. The

abdomen is slightly more ridged and corrugated than in the newly hatched larva

(vide Pl. 20. figs. 3, 4). Figure 4 is about three-quarters grown and shows the first

commencement of the wing-protuberances on either side behind the head.

Fully-grown Larva.—Swall, thick, puffy, wingless, dull purple-brown in colour, much

ridged and corrugated dorsally, the lateral edges crenulate, and the anterior cox

greatly enlarged and globose. Beneath the skin on each side of the mesothorax a small

dull yellow exerescence can be seen, and posteriorly to this on the metathorax, also at

the side, a longish dark flatter protuberance. These protuberances are the new fully-

developing wings. Legs and antenne yellowish green. Antenne six-jointed. No wool

is secreted by the insect at this stage. Length 1:14 to 1:35 millim. (Pl. 21. fig. 2.)

Winged Insect (AuaT#®).— After the last moult of the larval or nymph skin the Aphid

is very brightly coloured. Head and prothorax black and shining, mesothorax and

metathorax both dorsally and ventrally dark orange-brown. Wings pale apple-green

with yellow nervures. Abdomen shining black. Legs and antenne bright canary-

yellow. Short, thick-set, almost squarish, the body flatter than before the nymph’s

final moult. Head small; antennee six-jointed, the first jomt very small, second and

third small, fourth longest; prothorax broad and much channelled, the rest of thorax

CHERMES HIMALAYENSIS ON THE SPRUCE AND SILVER FIR. 105

also broad, the metathorax sessile on the abdomen. The wings project beyond the

posterior part of the body almost 1 times the total length of the Aphid. Length with

wings 2°25 to 2°68 millim. PI. 21. fig. 5 shows the fly newly issued from its last larval

skin with wings still rolled up; fig. 6 the perfect fly with wings fully developed ; and

fig. 7 the fly developing the white cottony material on head, thorax, and body.

Life-History.

An examination of the branches of the Spruce at the beginning of May will show

small pinkish-white cone-shaped masses appearing here and there. At the bases of

these, in the axil between the branch and cone (which is really an unopened bud), masses

of elliptical reddish-yellow eggs are to be found, sometimes very abundantly, at others

in much scarcer numbers. These egg-masses are partially covered by the dried skin of

what was the stem-mother, who dies after laying them. At the beginning of May these

egg-masses are in the majority, few of them having hatched out, and the bud above

them having only just commenced to increase in size. I have not as yet definitely

ascertained whether these eggs are laid in the spring or in the late autumn by the stem-

mother. A carefui search for eggs in October and November, 1906, in Jaunsar failed to

disclose any on the Spruce, even on trees bearing numerous old galls from which winged

insects had emerged the previous July. This would seem to point to the fact that the

stem-females (FUNDATRICES) on the Spruce hibernate through the winter with their

long proboscides fixed in the bast-layer of the stem just below a bud and lay the eggs

very early in the spring in April—in fact, before the first warmth of spring has made

itself really felt and whilst snow is still lying on the ground. This is what | think

myself actually takes place.

According to Burdon, it is the lengthy feeding of the mother by suction which

originates the gall-growth on the stem, the growth gradually spreading to and

enveloping portions of the needles in the European form.

In the first week in May small larve hatch out from the eggs, and sections cut across

any of the small cones, which have swollen to a slight extent, will disclose numerous

young larve between the bases of the young needles. These larvee are engaged in

feeding upon the sap of a part of the stem and the young undeveloped needles of which

the pink cone or gall consists. The irritation set up by the stem-mother feeding at the

base of the bud and perhaps by the young larve feeding at the base of the young

needles soon causes the bud to swell, but instead of opening out into a short stiff brush

of needles it develops into a green cone-shaped mass or gall. When this gall is quite

young there is no partitioning off into distinct cells to be observed within it; but as the

swelling under the constant irritation set up by the larvee and due to the growth of the

needles themselves continues, the interior gradually becomes divided off into distinct

compartments, in each of which numbers of the young larvee are to be found engaged

in sucking the sap from the walls of the compartment. PI. 20. fig. 2 shows a section

across a partially-grown gall with five compartments in it.

In the third week of May this partitioning is already distinct, and a section of a small

106 MR. E. P. STEBBING ON THE LIFE-HISTORY OF

eall—which is by then bright green externally and pyramidal or pear-shaped in form,

from which the European gall gets its name of Pine-apple Gall—will show a number of

chambers situated on either side of a central axis (ef. Pl. 20. fig. 2).

The young larvee are still a bright madder-brown in colour, with legs and antennze

light yellow. No indications of wings have yet made their appearance (¢f. PI. 20. fig. 8).

As the gall becomes partitioned off inside distinct diamond-shaped areas make their

appearance on the external surface, each of which serves as a cover to the chamber

below it. It will be noted that the galls terminate the shoots, being sessile at the top

of last year’s woody shoot (cf. Pl. 20. fig. 1). It would almost appear therefore as if the —

gall was a stem-grewth, and to some extent it must be so looked upon, for it is made up

of the young needles whose growth in length has been arrested and also of the tissues

which would have gone to make the new stem-growth of the year. If the centre of each

diamond-shaped cover be examined it will be seen that a central spot on the surface is

lighter-coloured than the rest and usually forms a small projection which is longer and

more apparent in the young gall than in the old one (cf. Pl. 20. fig. 1 and Pl. 21. fig. 1).

This projection would appear to represent the tip of the swollen-up and absorbed needle.

It is rarely more than an eighth of an inch in length and in this totally differs from the

European Spruce and Larch Chermes gall, in which only the lower portions of the needles

and shoot of the year swell up and coalesce to form the gall, the upper part of the needles

projecting to some distance beyond the gall-surface and being obviously the true upper

portion of the needle, whilst the upper portion of the shoot continues its normal growth

above the gall.

Mr. E. R. Burdon’s recent investigations from a botanical point of view on the origin

and development of the European gall * are of such interest that I feel no apology is

required for reproducing them here :—

“ As soon as the insect begins to suck in the spring, the cells in the region of the cambium where

the apex of the proboscis lies are forced into precocious growth. They at once increase rapidly in size

and undergo active division. The protoplasm becomes filled with large vacuoles and the nuclei enlarge

in about the same proportion. The daughter cells repeat the process aud the swelling and growth

radiate outwards in every direction from this centre.

“* At first the formation proceeds symmetrically and both the pith and the cortex are invaded to an

equal extent. Very soon, however, a limitation is imposed on the growth of the pith-cells by the

lignified vessels of the protoxylem, and the cells of this region do not continue to respond so readily to

the stimulus. The growth then takes the line of least resistance, and extending rapidly outwards

through the cortex becomes excentric. . . .

“The net result of these various changes is that almost all previous differentiation of the stem has

been obliterated, and in its place a parenchymatous tissue, consisting of abnormally swollen cells with

extremely thin walls, has been formed. The cortex on the galled side of the stem has become two to

three times as thick as the cortex on the other side which is still normal, and the symmetry of the stem

has thus been destroyed.

(1905), pp. 12-19. Vide also his observations on the subject in his other two papers in the Journ. Econ. Biol.

already referred to.

CHERMES HIMALAYENSIS ON THE SPRUCE AND SILVER FIR. 107

“The gall growth continues its outward course until it reaches the bases of the needles, and these in

their turn begin to swell up. As the growth proceeds up them the needles assume a tapering shape,

very much thickened at the base and gradually diminishing in size until about halfway up, where they

still remain normal. The gall is now visible to the naked eye as soon as the bud-scales are removed,

being rendered evident not only on account of its swollen nature, but also by reason of its bleached

appearance due to the absence of chlorophyll.

“The needles at first increase evenly in thickness on every side, but before long the swelling becomes

confined on the inner (ventral) side, since this faces the main axis, which is also swelling, and the two

soon meet. When this happens any further growth goes on chiefly on the dorsal side, and the leaf

becomes asymmetrical in transverse section. The outer (dorsal) side of the needles soon comes in

contact with the inner surface of the bud-scales, but as these are gradually unfolding all the time, they

do not offer much resistance to the swelling, and the dorsal side of each gall-needle consequently

becomes convex in shape.

“Owing to the erect position of the needles at this stage and their crowded spiral arrangement

round the main axis, this enlargement of their bases quickly results in adjacent needles coming into

contact with each other, and grooves are formed on the surface of each needle, where other needles

have pressed upon it. The phyllotaxis is such that the base of any one needle must on swelling come

in contact with the swollen bases of no less than four other needles, two belonging to the spiral above

it, two to the spiral below.

“ach needle-base is consequently marked with four grooves. Of these, the two on the inner side

are much deeper than the two on the outer side, owing to the pressure being greater in the former case,

and between these grooves a slight ridge is formed which corresponds with the space between the

needles of the spiral above, or below as the case may be.

“As the stem gradually elongates the needles are carried slightly apart, and the resulting space

above each needle forms a chamber which is later on taken possession of by the young offspring of the

Chermes mother. The deeply grooved inner (ventral) side of the needle forms the floor of this chamber,

whilst the two needles of the spiral above each contribute a half towards the formation of the roof. It

will thus be seen that each individual leaf participates in the formation of three distinct chambers, its

yentral side forming the floor of the chamber above it, and the grooves on its dorsal side each forming

one-half of the roofs of the two chambers below it to right and left.

“ At a later stage these chambers become closed in by the development of thick tumid lips around

their mouths.

“ About the beginning of May the shoots begin to emerge from the bud-scales, but the galls are not

at once visible, since the base of the shoot is still concealed in the persistent basal bud-scales. They

soon, however, make their appearance and the galls then enter on the second stage of their existence,

the history of which must be left at present as my examination is not yet completed.

“ But to return to the insect. Whilst the changes described above have been proceeding in the bud,

the Chermes larva has been steadily sucking and increasing in size. She has secreted a quantity of

white wool-like wax, which, while it entirely conceals her, renders her position most conspicuous. She

undergoes three ecdyses before reaching maturity, and the cast skins may be found lying beside her

in the ‘wool. As soon as she reaches maturity she commences to lay eggs, and continues the

process through May and on into June, until a heap of some hundreds of eggs accumulates beside

her. Each egg is attached to the stem by a delicate hair-like stalk. The first eggs begin to hatch

soon after the gall has emerged from the bud-scales, and the minute larve at once creep up

the shoot and establish themselves in the gall-chambers, where they find a fleshy succulent tissue

already prepared for them. They at once commence sucking and become entirely enclosed within the

chambers by the development of the tumid lips previously referred to, and here they remain until the

galls open.

SECOND SERIES.—ZOOLOGY, VOL. XI. 16

108 MR. E. P. STEBBING ON THE LIFE-HISTORY OF

“These, then, constitute the most important events which characterise the development of the galls

during the first stage—that is, whilst still enclosed in the bud-scales.

“One very noticeable feature is the apparent absence of any effort on the part of the plant to resist

the attack, for the insect appears to have everything its own way. ‘This is, I think, chiefly due to the

fact that the shoot is enclosed in the bud-scales, which exclude light and air, and thus keep the tissues

of the shoot in a plastic condition. ...

“ Although my examination of the later stages is not yet complete, I have seen enough to convince

me that the conditions are reversed in the next stage, and a great effort is made by the shoot to

overcome the influence of the insect. And this effort is to some extent successful, in so far as the shoot

is enabled to limit the insect’s sphere of influence to the area over which it has already gained sway.

But the effort is made-too late, and always ends in the death of the galled portion of the shoot, if not

of the whole shoot.

“With regard to the ultimate cause of the gall-formation, there is, I think, good reason to believe

that it is due to an injection by the Chermes mother. It would be out of place in this paper to give

the reasons for this belief in detail, but the behaviour of the chlorophyll, tannin, protoplasm, and nuclei,

and the gradual radiation of the influence in every direction all seem to point to an injection as the

cause. Further, if the imsect be removed, say a week after it has commenced to suck, the abnormal

growth is not brought to an end. The gall continues to develop, and emerges from the bud-scales

just as if the insect had never been removed, The only possible explanation of this posthumous

growth appears to me to be, that the poison injected during that week of the insect’s life continues to

act on the tissues of the plant after the death of the mother.”

The pseudo-cone caused by the Himalayan insect continues to steadily increase in size

throughout June and the young larve inside turn to a dark purplish-madder colour.

They moult their skins whilst in the chambers, at least three moults taking place, and the

white papery cast skins can be found in the chambers. When nearing their full growth

from six to eight or at times an even greater number of larva occupy each chamber.

Several pseudo-cones are often to be found on the same branch (¢éf. Pl. 20. fig. 1 and

Pl. 21. fig. 1), and I have at times seen young trees loaded with these galls, the latter

having all the appearance of true fir-cones, the great number present adding to this

deceptive appearance.

In the early days of July the young larve in the galls reach full growth and the

galls commence to open. It has been noted that those situated on sunny slopes and on

the sunny side of the tree open first.

The gall or pseudo-cone in the process of what may be termed “ripening” changes

from green to orange-yellow and pale crimson; this takes place first on one side after

the manner of a ripening apple and then all over, the gall often becoming bright

crimson for a time, finally turning, when the insects are ready to emerge, to a dull purple,

with the exception of a small patch or point in the centre of each of the diamond-

shaped covers (where the upper part of the needle would come off in the European

Spruce and Larch Gall), which remains bright green (PI. 21. fig. 1).

I give the following description (with some additions and corrections) of the opening

of the cone and the acquisition on emergence of their wings by the full-grown larvee or

nymphs from my paper already alluded to as published in the ‘Journal of the Asiatic

Society of Bengal ’:—

The cone does not necessarily commence opening at the top: the small chambers

CHERMES HIMALAYENSIS ON THE SPRUCE AND SILVER FIR. 109

may open anywhere all over it. The portions more exposed to the sun and in direct

contact with warm air-currents ripen first. An examination of the insects within the

galls, just before the latter begin to open, will show them to be little thickish, puffy,

wingless Aphids, dull purple in colour and much ridged dorsally, with greatly enlarged

globose anterior cox (Pl. 21. fig. 2). This is the last stage of development of the

insect within the gall, no functional alar appendages being present.

A section cut across the gall at this stage shows from 5 to 7 chambers of considerable

size (fig. 3), each containing on the average eight purple grubs amidst a mass of fine

white cottony material and cast larval skins.

In opening, the upper two edges or sides of the diamond-shaped outer covering of

the chamber become detached at their points of juncture with the two lower sides

of the cover of the chamber next above, thus forming a kind of lip purplish in colour,

which can be forced open with a forceps. The external surfaces of the diamond-

shaped coverings then contract slightly, thus causing the aperture to permanently gape,

the opening becoming wider and wider as the surface dries and consequently contracts

(figs. 1, 4). The slit is at first quite narrow, but as soon as it appears the insects

commence to crawl out. On reaching the outside of the false cone the fat purple

nymph (fig. 2) at once undergoes its last moult. In doing this, the skin splits down a

median line, both dorsally and ventrally, as far as the mesothorax dorsally, and the first

and second pair of coxee ventrally ; the insect then slowly crawls out, leaving the white

papery cast skin, to which are attached the dark-coloured leg and antenna cases,

behind it.

After this last moult it will be seen that the Chermes has undergone a great change.

It now appears as a small gorgeously coloured Aphid. On either side of the thorax

two little bright-coloured bundles are visible, a bright Naples yellow anteriorly and

vivid apple-green posteriorly (fig. 5). The whole insect, in fact, is very highly coloured

and looks at this stage as if it had just been freshly painted with the very brightest tints

in Nature's colour-box and then given a coating of varnish. As soon as the Chermes

has freed itself from the last attachment of its last skin it begins to crawl actively

about on the exterior surface of the gall, and the little yellow and green bundles unfold

and disclose the fact that they are the rolled-up alar appendages (cf. fig. 5). As far as

I could perceive, the insects themselves take no active part in unfolding these wings.

They do not hang themselves up to get them unrolled, as is the case with Lepidoptera,

but simply walk about, and under the influence of the sun and heat the wings rapidly

spread out, stiffen, and become functional. I noted that in many cases, even before the

insect has entirely freed itself from the last larval skin, the little bundles had so far

unrolled as to be quite distinct from one another. Within half an hour from the time

of leaving the cone, the wings are fully unrolled, being held at an angle on the side of,

but not meeting in a roof-shaped manner over, the abdomen. These wings are pale

apple-green in colour with yellow nervures except at their juncture with the thorax,

where they are chrome-yellow (vide fig. 6).

Within one and a half hours of shedding the last skin, patches of white setz begin to

appear upon the Aphid, and the meso- and metathorax turn from orange to shining

16*

110 MR. E. P. STEBBING ON THE LIFE-HISTORY OF

black. These hirsute white patches appear on the head, upon each division of the

thorax, and two little tufts, set side by side on each segment, run medianly down

the dorsal surface of the abdomen. On the prothorax these white sete are in a

transverse ridge; on the meso- and metathorax they are in two large patches as on the

abdomen. ‘The wings become a paler green or yellow, the costal and median nervures

being strongly marked and orange in colour, the transverse intersecting ones being

silvery (fig. 7).

The insect by now, 7. e. within three hours of its last moult, has lost all its brilliant

colouring and has: become dull and inconspicuous. It only differs from the winged

form to be found at this period on the needles of the Silver Fir by being colourless, but

iridescent in certain lights.

A certain proportion of this winged generation, which consists of females only, from

the Spruce galls fly off to the Silver Fir, where I have found them in the first half of

July clinging to the new year’s needles. The others remain on the needles of the

Spruce They bury their proboscides in the tissue of the under side of the leaf, taking

up a position parallel to the long axis of the leaf with head pointing downwards.

Summary.

We may summarise this portion of the life-history as follows :—

In the early spring the stem-mother lays a mass of eggs just beneath a bud on a

branch of the Spruce in the spot where she has hibernated through the winter with her

long proboscis fixed in the cambium layer of the branch. The irritation set up by the

sucking of the female has already resulted in the first beginnings of a gall the swelling

of which, commencing on the stem, subsequently envelops the whole of the developing

spring needles of the bud. The larve hatching out from the eggs at the commence-

ment of May get enclosed in this gall. The growth of the gall and the larvee continues

throughout May and June, the gall becoming mature or “ripe” and the larve fully

grown about the first week to middle of July. The gall differs from the European one

in that the whole of the needles become absorbed within it, only a minute portion of

the tip protruding from the hexagonal cap or lid forming the cover to each compartment

of the gall. The larve moult their skins several times during their growth in the

chambers of the gall. In July the lower edges of the caps or lids of the galls open,

the cap drying and shrinking, and the larvee craw] out of tle chambers on to the outside

of the gall. Here they at once cast their skins, the little flies crawling out. At this

moment the flies are highly coloured little insects, the wings being rolled up into little

bundles on the thorax; these rapidly unturl, straighten out and stiffen in the sun’s

rays, and become functional. Some of this winged generation, which consists of females

only, remain on the Spruce and lay eggs there; the rest fly to the Silver Fir and

oviposit on the needles or twigs. These eggs, or a portion of them, hatch out within

a week or fortnight, and give rise to a generation of larvee which crawl on to the

branches which have developed a first thin brownish-yellow cortex and bury their very

long proboscides deep down through a erevice of the bark into the cambium below. The

CHERMES HIMALAYENSIS ON THE SPRUCE AND SILVER FIR. iA

monsoon period and possibly the autumn and winter are passed in this position. I am

of opinion that it is possible that these insects form a portion of the stem-mothers or

CoLontict on the Silver Fir.

III. C#erues wIMALAYENSIS ON THE SILVER FIR.

Nature of Attack.

The Chermes feeds upon the sap of the new needles of the year, spending its life

invariably on. the under surface.

The second or third generations of the apterous insects descend down the needles

towards their bases, causing the needles to contort and screw up, the upper portion of the

shoot thus developing into a curious corkscrew, having the appearance of a large

terminal “bud” within which the Aphids feed, the whole mass being very sticky from

the exudations of the Aphid (éf. Pl. 28. fig. 1).

Distribution.

The same as already given under the Spruce.

Description.

Young (Cotonict) Larva.—Madder-brown to black in colour, covered with white

cottony bristles with a lateral fringe of white setze. Proboscis very long, at least more

than three times as long as insect, blackish in colour. PI. 23. figs. 2,3 show these

Colonici larve.

Stem-Mother (Cotontct).—Dead females are dark brown-madder to almost black in

colour with a long blackish proboscis.

Egg-Masses.—The spring egg-masses are very similar to those of the Spruce already

described, but they differ in one marked peculiarity. They are invariably covered by a

white cottony filamentous substance or ‘‘ wool,” which entirely hides and protects them.

Pl. 22. fig. 5 shows an egg-mass with the wool drawn aside to show the eggs.

This egg-mass contains the eggs of the second generation, the Srxupar# and

_ EXsues.

Eggs.—Similar to those found upon the Spruce.

Elliptical, yellow, darkening to madder-brown, shining, having tle shape of a hen’s

ege. Pl]. 22. figs. 3, 4,5 show masses of these eggs, those of the second generation

of the year.

Young larva (SpxuPaR® and ExsuLes).—Brown-madder in colour, with two large

basal joints to the antenna, followed by another joint and a bristle. Proboscis short.

Within a few days of hatching out, the young larva commences to secrete from

the dorsal area the white woolly substance which from now onwards begins to gradually

clothe them.

Pl. 22. fig. 8 shows a young newly hatched larva of the second generation from an

egg laid two days before by an apterous female of the first generation of the year.

full-grown Apterous Female (ExsuLEs).— Elliptical ovate or truncate ovate (figs. 2, 3),

dark madder-brown in colour, convex above and flat ventrally, the dorsal segments

well marked and ridged, the lateral edges flattened. Legs yellowish or madder-brown.

When full-grown the insect is usually entirely enshrouded in a thick mass of long fine

filamentous wool. This wool is secreted from the segmental divisions of the thorax and

body. Length about 1:25 millim. Pl. 22. fig. 2 shows a female without the ‘ wool”

covering, just before egg-laying, fig. 8a female just commencing to develop the wool

covering and to oviposit, and fig. 4a female with the eggs almost fully if not completely

laid and covered to a great extent with the wool covering (some of it in the drawing

has been removed to show the eggs).

Pull-grown Larva or Nymph (Srxuparz).—Elongate elliptical, pointed at both ends.

Shining, madder-brown, with two dull yellow swellings on either side of the thorax,

which are the wings beneath the skin, and give a humped appearance to the thorax

dorsally. The transverse annuli of the body are faintly visible. Body very convex

dorsally, the lateral edges set with a longitudinal row of tubercles. Length about 1°45

to 1:55 millim. (Pl. 22. fig. 6.)

Winged Insect (SEXUPAR&).—Umber-brown to blackish, with four transparent wings

with a faint brownish tinge, the base of the main vein yellow medianly, otherwise all the

veins brownish. Head umber-brown, with exserted antenne, 4-jointed (or 5-jointed, the

oasal joint very short), 1 (or 2) thick, square, short, other 3 narrower than 1, elongate,

swollen medianly, last shortest. Thorax black, emarginate anteriorly, with a flat

elongate heart-shaped raised edge medianly, enclosing a smooth depression having

this shape C= on prothorax and a prominent lateral spine on side of mesothorax.

Body black, rather flat, the abdominal margin of the segments prominent. Legs dull

um ber-brown.

No ‘‘ wool” material visible on the insect when it first issues from the ruptured skin

of the nymph.

Some twelve hours after leaving the skin of the nymph, short curling white cottony or

“wool” filaments begin to appear :

(1) At base of head at its junction with the prothorax.

(2) Two circular patches placed transversely in the sunken depression on the

prothorax.

(3) An irregular patch on the meso- and metathorax.

(4) A much larger continuous mass of wool filaments completely covering the dorsal

surface of the abdomen.

Pl. 22. fig. 7 shows this fly when it has just begun to develop the woolly masses on

The winter is passed in the stem-mother (CoLonicr) stage, the insect remaining on the

branches or, in the case of young trees, on the upper part of the main stem, with her

long proboscis buried in the cambium layer of the tree. The insects generally occupy

crevices of the bark.

The stem-mothers must awake into activity very early in the year and oviposit, for I

CHERMES HIMALAYENSIS ON THE SPRUCE AND SILVER FIR. 113

have found the egg-masses and wool-coverings at the beginning of May at elevations as

great as 9300 ft., whilst snow was still lying upon the ground.

At times these woolly egg-masses are so numerous as to clothe the bark of the stems of

young trees more or less entirely from top to bottom, either encircling the stem or

occupying one or two sides only. Or the eggs may have been laid on the upper portion

of the stems of old trees and poles or on parts of the side branches. Tops, leading shoots,

and branches covered in this manner have the appearance of being infested with the

white filaments of a fungus (ef. Pl. 23. fig. 4).

An examination of these cottony masses with a lens early in May will show that the

wool-like material merely serves as a protection to a blackish skin, the dried-up remains

of the over-wintering mother. This skin partially covers the bunch of yellowish-brown

glossy elliptical eggs. We have seen in the case of the Spruce that the eggs are merely

partially protected by the dried female skin, no cottony material being excreted by the

stem-mother (Funpatricss). The eggs, laid anywhere on the bark of the stem of the

Silver Fir, appear to require more protection than in the case of those laid beneath tie

immature buds on the branches of the Spruce; and this would seem to be the reason for

the development by the Cononicr mothers, and, as we shall see, by the apterous females

of the spring generations, of the cottony mass to serve as a protection to the eggs.

I have found the eggs in millions upon Silver Fir trees in years of bad infestation.

In the first week of May small larvie (¢f. Pl. 22. fig. 8) hatch out from the eggs, and

these at once crawl up on to the newly developed or developing needles of the tree, at this

period just bursting through the bud-scales, where they appear as minute black specks

covering the bright green tassels of needles. They insert their proboscides into the tissue

of the under surface of the needle and remain fixed in this position. They are never to

be found on the upper surface of the needle. These larvee resemble exactly the young

larvee to be found at this period within the newly forming pine-apple galls or pseudo-

cones of the Spruce. Within a few days, however, the young Aphids on the Silver Fir

begin to secrete on the dorsal segments a white cottony material, which is extruded in

bunches from certain parts of the segments and serves undoubtedly as a protection to

screen the grubs from the eyes of predaceous birds and insects, &c. ‘To the naked eye

the young grubs appear at this period to be attacked or surrounded by the fine white

filaments of a fungus.

Towards the end of the third week in May, after at least two moultings (I think the

total number is 3) of the skin, the grubs mature, and at this period some at least lose the

white cottony covering and appear as the ovate brown apterous female shown in figure 2

in Plate 22.

These are the ExsuLzs, or apterous insects, which remain on the Silver Fir.

These apterous females as soon as mature begin to develop cottony material, the first

filaments being secreted from segmental divisions of the head and thorax. Soon after

filamentous masses are extruded between the abdominal segments, and the whole insect

is almost entirely covered by the woolly mass. As soon as the first cottony filaments

have begun to make their appearance the apterous female commences egg-laying, the

eggs being extruded from the anal end of the body (fig. 3). These eggs are lightish

114 MR. E. P. STEBBING ON THE LIFE-HISTORY OF

yellow at first, darkening to a yellow-umber or madder-brown in a few hours after being

laid. About 30-40 are laid by the female, a day being spent in this operation, the

female subsequently dying and her shrivelled skin remaining as a partial protection to

the eggs beneath the cottony mass. Pl. 22, figs. 3 and 4 show the apterous female

egg-laying and with the eggs completely laid, the figures in both instances being drawn

from life under the microscope. The majority of the spring larve of the first generation

are apterous females and lay their eggs in the third and fourth week in May.

A small proportion of the spring larvee develop into a winged generation of individuals

(the SEXUPARS ?) on the Silver Fir.

The full-grown larvee, which will produce the winged insect, are easily recognisable on

the Siver Fir needles under a lens, owing to their narrower elongate elliptical shape and

to the light yellowish-brown swellings visible on either side of the thoracic region

(fig. 6). The skin of this larva bursts open at the head and thoracic end and the winged

insect with its wings furled in two little bundles on the thorax crawls out. The wings

uncurl, soon dry and stiffen in the sun, and become functional (fig. 7).

I have not been entirely able to settle the movements of the whole of this winged

portion of the spring generation of larve. It may be that some of them fly off to the

Spruce to oviposit there, but I have not as yet been able to find any individuals of this

winged generation on the Spruce.

They are to be found not unfrequently on the Silver Fir needles with their proboscides

buried in the tissue of the under surface of the leaf. A proportion of them, I think,

undoubtedly lay eggs on the under surface of the Silver Fir needles in a similar manner

to the apterous females, and, this being so, the speculation arises as to why they should

have acquired wings. It is true that the possession of alar appendages enables them to

migrate from the needles upon which they were reared to others in the neighbourhood

which are not occupied by numbers of egg-masses, and this may be the reason for a

proportion of the young larv growing into a winged generation. I think, however, the

most reasonable surmise is that a percentage of these migrate thus early in the year to

the Spruce. If this is the case, they form the true Generation IV., the SEXUPARA, or

the first portion of it, of the year, provided the eggs they lay upon the Spruce give rise

to a sexual generation. Further observations by fellow-workers on this interesting

portion of tle life-history will settle this point definitely.

That a portion of the winged generation would seem to remain on the Silver Fir I have,

I think, proved by the following observations :—On the 24th May I described a winged

living individual under the microscope, and kept it under observation on the 25th and

26th. On the 24th the insect had merely issued from the last larval covering, acquired

its functional wings, and taken up its position head downwards with its proboscis buried

in the tissue of the under surface, the last larval skin being close by adhering to the

needle. On tle 25th the insect had darkened in colour, and had commenced to develop

short cottony filaments as follows :—

(1) At base of head at its junction with the prothorax.

(2) Two circular patches placed transversely in the sunken depression on prothorax.

(3) An irregular patch on the meso- and metathorax.

CHERMES HIMALAYENSIS ON THE SPRUCE AND SILVER FIR. 115

(4) A much larger continuous mass of cottony filaments completely covering the

dorsal surface of the abdomen.

On the 26th the cottony mass had increased and egg-laying commenced. ‘The fly died

on 27th or 28th.

This fly was drawn on the 25th May and is shown in PI. 22. fig. 7.

We thus see that from the spring generation of larvee two forms develop, one apterous

and the other winged.

The whole of the apterous forms and a portion (or all?) of the winged forms at once

oviposit on the Silver Fir needles, laying masses of eggs which resemble the spring ones

and are covered with very visible white cottony filamentous masses. Pl. 22. fig. 1

shows a portion of a Silver Fir branch exhibiting these white cottony masses on the

needles, which cover either females still egg-laying or masses of eggs partially shielded

by the dead skin of the female insect. This figure was painted from life, the branch

having been just previously plucked from a tree.

The eggs of this second generation of the Aphid hatch out in from two to three days

after being laid, and the young larve spread out over the under surfaces of the still

young and soft light green needles, insert their proboscides into the leaf-structure, and

remain feeding either in one place for the rest of their lives or more usually shift their

feeding-spots later on in their development. At times the under surfaces of the needles

are quite black with numbers of the dark madder-brown coloured larve attached to

them, which appear to the naked eye as tiny black dots on the needles. If the needle is

closely inspected it will be seen that it is always bent upwards a little on either side at

the point at which the larva has been feeding.

Observations have shown that some of these larve develop into apterous females about

the middle of June and lay eggs, at least a portion of which also produce another

generation of the apterous females.

At the beginning of June it will be noticed that the greater proportion of the larvee

feeding on the needles of the upper or terminal portion of the new shoot have collected

towards the bases of the needles and on the needle-bearing stalks, and this results in a

curious malformation of the Silver Fir shoot (cf. Pl. 22. fig. 1). The irritation set up by

the feeding larve causes each individual needle to cockle and twist over in a spiral

direction from right to left. The needles so affected appear to lose their chlorophyll and

turn a dirty yellow, cither all over, or have numerous small yellow blotches amongst the

green all up them. As the green needles of the whole of the upper half of the shoot of

the year are affected in this manner, it results in this portion of the shoot becoming

twisted up into a corkscrew mass, as shown in Plate 23. fig. 1. The tightness of the

twist varies, but it is such that the needles so affected remain in this position and finally

drop off. During the insects’ presence the heavy exudation of sugary liquid from them

covers the corkscrew mass and binds the needles yet more firmly together, giving the

shoot the appearance of being terminated by a giant bud. I have noticed also that

this excretion is added to by an exudation of turpentine from the Silver Fir, round

nodules of resin being formed in the axils of the affected needles.

An examination of the corkscrew masses at the end of the first to the second week in

SECOND SERIES.—ZOOLOGY, VOL. XI. 17

116 MR. E. P. STEBBING ON THE LIFE-HISTORY OF

June will show numbers of the ordinary madder-brown larvee feeding at the bases of the

needles and on the stem, and also, in addition, some larger yellowish grubs which now

begin to make their appearance for the first time. These yellow larvee are usually found

in the axils of the leaves, each having its proboscis firmly fixed in the tissue of the stem

or base of the leaf.

We have here the distinct separation of the last generation of the insect passed during

the year on the needles of the tree into two distinct forms of larvae. The yellow larvee

give rise to a generation of winged insects which form either the latest portion of, or the

true, fourth (SEXUPAR#) generation. The larve remain feeding in this position until

the middle to the end of the third week in June or even until the end of the month,

the period apparently depending almost entirely, if not entirely, on the nature of the

season experienced. If a hot dry spring followed by a late monsoon is experienced, the

Aphids may be found in the corkscrew masses up to the end of June. If a wet spring is

followed by an early monsoon (as in 1909), an examination of the corkscrew masses in

the third week of June will show them to be dried up, open and empty.

At whatever time the yellow larve mature, it will be found that just before this.

period the insects apparently cease feeding or cease exuding sugary material, The

corkscrew needles now dry and shrink apart slightly, and the small apertures so left

enable the yellow larvee, or nymphs as they now truly are, to crawl through. They creep

out onto one of the lower needles or onto the stem, moult their skin, the skin splitting

down anteriorly to the metathorax, and the winged insect with the small bunches of

wings on the dorsal anterior surface crawls out, much in the same manner as the winged

insect of the Spruce gall leaves its larval skin, and as the first generation of winged

insects on the Silver Fir leave their nymph-skins.

The numerous white paper-like skins on the twigs and the untwisted needles in the

neighbourhood of the large “ bud ” are easily visible.

The winged generation of flies resulting from these yellow nymphs act in two ways.

Some remain on the Silver Fir and lay eggs covered with cottony masses on the branches

and bark of the main stems of young trees and on the branches and upper part of the

main stems of old trees. The remainder leave the Silver Fir and migrate to the Spruce,

where I have found them fixed to the needles of the tree. Here they probably lay

the eggs which give rise to the sexual generation (SEXUALES) on the Spruce. This

generation I have not yet found.

The apterous females arising from the madder-brown larve move from the interior of

- the corkscrew mass down onto the untwisted needles and shoots below before egg-

laying. The greater bulk of the eggs laid beneath the cottony masses are always to be

found here outside and below the corkserew mass; and there is a good reason for this,

for the needles of the corkscrew, together with the portion of the shoot bearing them,

as I have said, shrivel up and fall off. The other needles of the year, below those which

actually formed the corkscrew, turn yellow in colour or have numerous spots and dots all

up them, and in their turn wither and die, but at a later stage.

The eggs, within a week or a couple of weeks of being laid, hatch out into tiny gruls,

CHERMES HIMALAYENSIS ON THE SPRUCE AND SILVER FIR. 117

blackish brown in colour, wiih a very long proboscis and the dorsal surface covered with

white cottony bristles, the lateral edges being set with a fringe of white sete, giving the

insects the appearance of an Jcevya scale insect in miniature (Pl. 28, figs. 2, 3).

These little grubs proceed down to the parts of the shoot or branches covered with

the first light thin brownish-yellow cortex, insert their proboscides down through a

crevice into the cambium layer and remain feeding there. Pl. 23. fig. 2 shows these

small larvee feeding on the cortex, and fig. 3 two more highly magnified. The larve

pass through the monsoon rains and, I think, the autumn and succeeding winter here,

and form a portion of the CoLonict, or apterous females, which lay the eggs of the first

spring generation of the year. The other or true portion of the Cotontct on the Silver

Fir migrate from the Spruce about the middle to third week in July. It is a point

which will require very considerable investigation and close experiments to decide

whether any of the apterous females (the true ExsuLEs) which leave the Silver Fir

corkscrew “bud” and lay eggs below give rise in the following year to winged insects,

or SEXUPAR.

We have now to turn to the winged insect which emerges from the Spruce pine-apple

gall, or pseudo-cone, and flies to the Silver Fir. This period of emergence is about the

middle of July, and a large proportion of the flies from the Spruce galls would seem to

migrate to the Silver Fir, for I have found them plentifully on the under side of the

needles.

On reaching the Silver Fir the fly selects a needle below the corkscrew “bud” and

comes to rest on the under side in a position usually pointing up and down or parallel

to the long axis of the needle, the head pointing either upwards or downwards, most

usually the latter.

The fly then commences to oviposit, laying from 60 to 80 or possibly as many as 100

eggs. The number is far greater than that of the eggs laid by the apterous female

on the Silver Fir.

The eggs are egg-shaped, dark madder or umber-brown in colour, and are deposited

in a heap like a squashed bunch of grapes, except that the mass is more spread out at

the base. The eggs when first laid are flesh-pink in colour, soon darkening.

The abdomen of the fly shrivels up after egg-laying and the upper wings remain

entirely covering the egg-mass, the insect dying ém sitw and remaining fixed to the

needle on taking up her position there.

Before egg-laying the fly develops on her head and thorax a white woolly material,

which projects in front of the head and down the sides a little way in a manner similar

to that already described for the Silver Fir fly.

When the fly gets blown or knocked off the needle, which, owing to her fragility, must

soon happen, the cotton remains as a covering and protection to the eggs.

These eggs would appear to hatch out within a few days after being deposited, and the

young grubs crawl down onto the shoots or branches from the needles and feed in the

manner already described, their long proboscides being buried in the cambium down

through an interstice of the bark (Pl. 23. figs. 2, 3).

Lae

118 MR. E. P. STEBBING ON THE LIFE-HISTORY OF

The life-history of the insect on the Silver Fir would therefore appear to have been

worked out with some completeness, were it not for the fact that during an autumn

tour in the Himalaya, made between the end of September and the middle of November

1906, I discovered dead winged individuals of this insect in some numbers on the under

surface of the Silver Fir needles towards the end of September and beginning of October.

Now these flies could not have occupied this position throughout the heavy monsoon

rains in July and August without getting washed off. A simple explanation for this

may be that they come from Spruce galls which had not opened before the monsoon

broke and which had only matured at this period.

Failing such an explanation, it would appear possible that a generation of the apterous

females (ExsuULEs) may lay eggs towards the beginning of September and that the winged

flies had arisen from a portion of these eggs. I could find no eggs upon the trees.

Summary.

We may summarise this portion of the life-history as follows :—

In the early spring egg-masses covered with a woolly material are found on the bark

of the main stem and branches of saplings and on the branches of older trees. As the

young needles of the Silver Fir unfold from the buds these eggs hatch out and minute

grubs crawl up onto the young tender spring needles, insert their proboscides into the

tissue of the under surface of the leaf and feed there. In about three weeks, after several

(probably usually three) moults, the larger portion of these larvee mature as apterous

female insects, develop the white cottony material, and commence egg-laying. <A portion

of the spring eggs, however, produce larvee which, when full-grown, are easily distinguish-

able from the apterous female larvze. These larvee or nymphs, which are to be found

much more rarely upon the trees, shed the last larval skin (this being the fourth moult)

and a winged insect emerges. These winged insects appear to mostly lay eggs on the

Silver Fir needles. It is possible, however, that a certain proportion migrate to the

Spruce.

From this first generation of eggs laid about the third week in May new minute larvee

emerge in from 2-3 days and spread out over the Silver Fir needles now grown to some

length. They may be often seen thickly studding the needles as minute black specks,

looking rather like a fungus attack on the needles.

From these larve a second generation of apterous females may be developed in

favourable dry hot years. Usually, however, it will be observed that when the young

larve are about a week old they collect down towards the bases of the needles and

feeding here set up an irritation which results in an exudation of turpentine, and also —

causes the uppermost new needles of the year to curl up in a corkscrew manner, the

sticky excretions binding them together into a large twisted “bud.” Within the cork-

screw “ bud ” larvee of two kinds will be found, the normal madder-brown coloured ones

and others with a yellowish tinge. The former develop into the apterous females and

lay eggs either on the needles below the corkscrew mass or on the stem below it.

The yellowish larvze leave the corkscrew mass on becoming full-grown, the needles by

CHERMES HIMALAYENSIS ON THE SPRUCE AND SILVER FIR. uae,

this time having dried and shrunk apart to some extent, thus permitting the exit of

the larvee. These larvee or nymphs shed their last skin and emerge as winged insects.

A portion of these winged individuals remain on the Silver Fir, develop a cottony

material, and oviposit on the needles or stem of the tree, the egg-masses being covered by

the cottony substance. The remainder of the winged generation migrate to the Spruce

and are to be found on the needles of that tree. These probably give rise to a sexual

generation (SEXUALES) upon this tree.

Thus by the end of June we have on the Silver Fir egg-masses covered by a cottony

material laid on the needles or on the bark of the stems of saplings and branches of

older trees. The position is therefore much as it was at the end of April.

These eggs hatch out within a week or so, giving rise to tiny blackish-brown insects

covered with white cottony bristles and edged with a fringe of white sete, which crawl

onto the stems covered with a first young cortex and bury their long proboscides through

crevices into the cambium layer below (Pl. 23. figs. 2, 3). These larve are a portion of

the CoLonicr and remain here through the rains and through the ensuing autumn and

winter, eventually laying the eggs of the spring generation.

It would appear possible, however, that some of the Exsules may mature and lay

eggs in the early autumn towards the close of the monsoon about the beginning of

September, since I have found dead winged flies very commonly with their proboscides

fixed on the under side of the needles of Silver Fir at the end of September and

beginning of October. These flies could not be those which issue from the pseudo-

cones on the Spruce in the middle of July and migrate to the Silver Fir, for such

minute fragile things could never pass two months in such an exposed situation as the

under surface of a Silver Fir needle during the monsoon season without being blown or

washed off.

I can only at present account for the presence of these winged individuals on the

Silver Fir at this period by the above supposition, unless the winged insects come from

some belated Spruce galls which did not open before the monsoon broke over the hills.

passed through on each.

V. DAMAGE COMMITTED IN THE ForEST BY CHERMES HIMALAYENSIS.

The Chermes when abundant undoubtedly greatly interfere with and retard the

erowth of young trees of both Spruce and Silver Fir.

In the case of the Spruce it is a common sight in the Western Himalaya to see young

trees loaded with galls, as many as 80 per cent. of the branches bearing at times several

pseudo-cones apiece upon them.

The Spruce only produces a few buds in the axils of the leaves, the majority of the

axils being without them. All these buds develop in the spring, no reserve stock being

available to replace casualties. Thus whena young tree is severely attacked practically the

whole of the growth of the year is lost. When this attack is repeated year after year the

tree becomes thin and straggly in growth, bears numerous unsightly dry black dead galls

upon its branches, has a scraggy appearance, and gradually becomes moribund and dies.

Development during the years 1902 to 1904 of a healthy Development during the same period of a Spruce

Spruce shoot (Picea eacelsa, Link), which was laid shoot with five buds, which was taken from the

down in 1901 and bore five buds. same tree as fig. 1, but was attacked by Chermes

in the first two years.

Mr. Burdon in his paper already quoted described an experiment carried out by

himself to ascertain the damage done by Chermes on the Spruce. He proved that a

shoot starting with a crop of five buds galled by the Chermes lost the majority in three

years. On this he wrote :-—

“Tt has been stated that the damage done by Chermes on the Spruce is not ofa

serious nature, but I think the above facts are sufficient to show that the injury is by no

means to be lightly regarded, and any one who compares healthy trees with those which

have been galled year after year will at once realize how extensive and far-reaching is

the injury caused by Chermes.”

122 MR. E. P. STEBBING ON THE LIFE-HISTORY OF

An illustration such as the above detailed one carried out by Mr. Burdon will appeal

most forcibly to the forester, for he can appreciate at a glance the tremendous damage

being done to his young growth if much of this sort of thing is taking place amongst it.

T have little doubt that were experiments of this nature carried on over a period of

years in, for instance, a Spruce area in Jaunsar, where the Chermes is abundant, results

of a similar nature to those arrived at by Mr. Burdon at Cambridge would be recorded

from the Himalaya. And the damage done by our Himalayan insect is much more

severe, since every infested bud, 7. e. shoot, means the total disappearance of that shoot.

On the Silver Fir, again, the growth of young trees is seriously impeded owing to the

peculiar method of feeding of the later generations, or second generation, of the CoLoNnicr

(the ExsuLes and SExupar#&). This results, as we have seen, in a contortion and dwarfing

of the upper parts of the new shoots attacked by the insect, the needles on the upper

half twisting round one another tightly to form a loose kind of gall-like structure, the

needles of which subsequently wither, dry, and open to allow of the exit of the insects.

This upper part with its portion of the stem turns yellow and drops of.

An experiment of a similar nature to Mr. Burdon’s with the Spruce would be of high

interest to ascertain the damage done to young trees by this curling up of the ends of

the new growth of the year.

This is not the only damage done to the new year’s shoot, as many of the lower needles

of the year are attacked by Chermes grubs either before they have moved into the

corkscrew or by those which remain outside. Each one of these at the point where

it pierces the tissue of the leaf and feeds causes the chlorophyll to be destroyed,

and the needle becomes bent at the point, the upper portion often drying up and

dropping.

I have seen (it is a common sight in parts of the hills) young trees with 90

per cent. of the new shoots corkscrewed up in the above-mentioned manner, whilst the

branches below and the main stem showed numerous patches of the cottony egg-masses.

The eggs in these cottony masses we have seen hatch out into the young grubs shown in

Pl. 23. figs. 2, 8, and these would appear to pass the rest of the year and the winter

sucking the sap from the young cortex-covered branches through their long proboscides.

I have found these larvee in thousands upon the branches of young trees in late July,

and the drain they must exert upon the young trees cannot but be otherwise than most

prejudicial to their growth.

Of course the habit of growth of the Spruce and Silver Fir in mixture in the Himalaya

facilitates the increase and distribution of the pest. The insect is certainly responsible

to a far greater degree than we foresters in India have realized for the poor state of the —

young growth of Spruce and Silver Fir in many parts of the Western Himalaya.

In young badly-infested plantations it might be serviceable to snip off the galls from

the Spruce before the flies issue, since in the case of the Indian insect the whole of the —

shoot is usually affected in their formation, and thus there is no chance of any further

growth being obtained from it.

My acknowledgments are due to my friend Mr. E. R. Burdon for his courteous

permission to reproduce the two text-figures on page 121.

VII. Some Points in the Anatomy of the Larva of Vipula maxima. A Contribution

to our Knowledge of the Respiration and Circulation in Insects. By JAMES MEIKLE

Brown, #B.Sc., F.L.S.

(Plates 24-27.)

Read 5th May, 1910.

THE respiration of Insects has always presented features of difficulty. In land forms,

with spiracles arranged in series along the sides of the body, a closing apparatus is

present which seems to aid in forcing the renewed air into the minute tubules of the

tracheal system. The air is probably renewed largely by diffusion. In many aquatic

forms, however, there are no open spiracles, but tracheal gills occur, through the walls

of which air must diffuse into the ramifying air-tubes contained within the gills. An

intermediate type is met with in the so-called “ metapneustic ” forms, where the air-

tubes are open at the posterior end only through one pair of spiracles. One must

suppose that greater difficulty will be experienced in these types in renewing the air

contained in the smaller branches, and some additional structures might be supposed to

be necessary. Further, no closing apparatus (valves) seems to occur within these

spiracles, and no regular contractions (‘‘ breathing movements”) of the body can be

distinguished.

It was to study a form of this kind that the examination of the larva of Tipula was

taken up, in the hope that it might throw some light on the question.

Further, in three such larve as those of ZY. oleracea, T. maxima, and T. eluta we

have a progressive series, for the first is terrestrial, the last aquatic, and the second

amphibious, and it was hoped that some progressive modification from land to water

mode of life might be discovered. This has proved to be the case to some degree.

The most detailed study was made with the larva of 7. maxima. Specimens of different

age were kept alive and observed. Some were traced through their transformations.

The structures were worked out, partly by dissections and partly by serial sections,

Material was fixed in different ways, but picro-corrosive, and a mixture of picric acid,

corrosive sublimate, acetic acid, formol, and alcohol, used hot, gave the best results.

Various stains, including iron-hematoxylin, Delafield’s hematoxylin, heemalum, orange G,

fuchsin, and eosin, were tried. Living specimens were injected with carmine to

determine, if possible, the function of the pericardial cells.

My best thanks are due to Prof. Denny, M.Sc., for advice throughout the work, and to

My. T. J. Evans, B.A., for suggestions and help in staining and preparing sections.

126 MR. J. M. BROWN ON THE ANATOMY OF

THe Larva oF Zvpuna Maxima. (P). 24. fig. 1.)

This larva, a form of * leather-jacket,” is found beneath stones, either close to or

in the bed of streams, at almost all seasons of the year. It is a vegetable feeder,

consuming leaves and roots of grass, and also apparently swallowing quantities of soil.

It is a sluggish creature, burrowing in the damp earth, and its burrows can be followed

for some distance. It pupates about June, in the earth, and emerges during July

or August.

The larva, when: full-grown, is about 13 inches in length. It presents the following

external features :—

1. The strong chitinous capsule (‘‘ head”) bears the jaws and serves to support the jaw-'

muscles, but does not contain the “ brain.”

2. The érunk is composed of 11 segments, more or less similar to each other, with

the exception of the posterior one. The head-capsule is completely retractile within the

first segment. The segments increase in size towards the middle of the body, where

they become indistinctly ringed externally into two; but this division does not correspond

to internal segmentation, except that the alary muscles of the “diaphragm” are

attached to the body-wall at the extremities and also at the middle points of the

segments (Pl. 27. fig. 19). The hindmost segment is different from the others, and,

besides bearing the anus.ventrally, appears to be modified in relation to respiration.

No indications of limbs occur on any of the segments.

The hindmost segment (Pl. 24, figs. 2, 3,4, & 5) is obliquely truncated behind. This

truncated region, which is surrounded by three pairs of flattened triangular processes,

bearing along their margins a fringe of strong hairs (m,f.), includes the two spiracles

(sp.), which appear as dark, broadly-oval spots, lying within a somewhat saucer-shaped

depression. By the folding inwards of the processes or lobes the spiracles can be

completely enclosed within a cavity, the stiff fringe serving to contain an air-bubble at

the same time. This generally occurs when the larva withdraws itself beneath the

water. Hach of the dorsal lobes bears in addition to the marginal fringe a specially

long sensory hair (s.4.) at its apex, and three others (s.4.,) symmetrically arranged, but

of different character from the first one. The structure of the spiracles is described

below.

The ventral surface of this segment (Pl. 24. fig. 3) carries the anus (a.) in the midst

of a raised and somewhat swollen area. This raised area serves also to give origin to

- four pairs of hollow, unjointed, palp-like processes (Pl. 24. figs. 2, 3, & 4, 0.g.). Two

pairs, one anterior to, and the other lateral to the anus, are long, tube-like structures

tapering towards their extremities, freely movable and specially extended when the larva

is below water. two much smaller pairs—in fact, mere pointed outgrowths—ocecur

in positions shown in the figures. From their structure and relations these seem to

serve as “ blood-gills.’ They contain each a branch of the tracheal system, and a strong

flow of blood is maintained through them. They are not present in the common leather-

jacket (Z. oleracea), which lives in fields, while in the larva of Z. eluta they are still

more prominent, the larva being more completely aquatic,

;

‘

THE LARVA OF TIPULA MAXIMA. 127

Respiration.

The respiratory system consists essentially of a pair of large longitudinal tracheal

trunks lying dorsal to the pericardial diaphragm (P]. 27. fig. 19, ¢r./.), and traversing

the body from the posterior segment to about the middle of the first body-segment,

where they end blindly in connection with the body-wall, at positions where the

respiratory trumpets of the pupa will open. From these longitudinal trunks, branches

arise segmentally to supply the body-wall and viscera (see Pl. 27. fig. 19).

The lateral trunks communicate with the exterior through the pair of spiracles on

the hind face of the posterior segment.

The spiracles themselves are of complicated structure (see Pls. 24 & 25. figs. 4, 6, 7,

8, & 9). Externally they appear as broadly oval dark spots showing in surface view

two distinct regions :—

1. A central area consisting of an imperforate disc of chitin occupying about one half

of the total diameter (sp.d.).

2. A surrounding margin (sp.m.) formed of numerous rods of chitin radiating from

the central disc to the circumference of the spiracle, and lying side by side so closely as

to leave but very narrow slits between them. ‘These slits appear further to be crossed

by numerous transverse connections, giving the whole a lattice-like appearance. Air

enters between the radial bars. Seen in sections this marginal lattice-work is formed

of three sets of parts :—

1. Passing in a radial direction from the margin of, the spiracle to the central dise,

but at a lower level than the outer surface (and hence not seen at all in surface view),

is a series of hollow chitinous radial bars (7.6.1.), irregularly oval in section, some bifur-

cating towards the centre, while others are joined with their neighbours by connecting

branches.

2. Arising from these are the series of Y-shaped upstanding chitinous pillars (Y.),

each of the radial bars bearing a complete series.

3. Supported by the upper ends of contiguous Y-pillars is a second series of radial

bars (r.b.u.), slightly flat-topped but wedge-shaped below. These being supported by

branches of neighbouring Y-pillars will necessarily alternate with the lower radial bars.

Further, these are the bars seen in surface view, the transverse connections being the

Y-pillars seen from above.

To complete the structure the Y-pillars are connected together by very numerous and

excessively fine chitinous threads (f./.), which branch and intercommunicate, the whole

forming a close network.

This spiracle cover appears quite incapable of closing, and the arrangement seems to

be a complicated form of filtering apparatus, probably also preventing the entrance of

water to the spiracles when submerged.

The spiracles open, not directly into the longitudinal tracheal tubes, but into two

“ stigmatic chambers,” which, in turn, lead into the tracheal tubes (PI. 24. fig. 6, st.ch.).

The “stigmatic chambers ” are tubular or cylindrical pits, almost circular in trans-

verse section, but expanded ventrally immediately within the spiracle.

19*

128 MR. J. M. BROWN ON THE ANATOMY OF

In the walls of the pits the following layers can be distinguished (Pl. 25. fig. 10):—

1. The hypodermis, consisting of regular block-shaped cells with large nuclei (hyp.).

2. The laminated cuticle (cut.), moderately thick, having the same characters as the

external cuticle of the body-wall. From this cuticle there arise large numbers of

chitinous hair-like outgrowths (ch.), projecting into the stigmatic chamber and forming a

very dense lining to it. Hach hair gives rise to side branches which unite with those of

neighbouring hairs, in much the same way as was noticed in the hairs of the Y-pieces of

the spiracle cover. ‘This lining covers the whole internal surface of the chamber, except

where the bunches of trachez arise, and seems to take the place of the teenidia

common to trachew. [In one of my series of sections these same hair-like outgrowths

occurred in a branch tracheal tube in the mid-region of the body, in place of the usual

spiral thread. |

At frequent intervals along the length of the stigmatic chambers bunches of clear-

walled tubes, without “spiral thread,” and enclosed in a nucleated sheath, take origin

(Pls. 24 & 25. figs. 6 & 10, ér.dd.). These bundles radiate on all sides from the chamber,

passing outwards and somewhat forwards, divide into smaller and smaller bundles by

the separation of groups of tubes. A short distance from the stigmatic cavity the

nucleated sheath ceases, after which large nuclei occur at rather rare intervals amongst

the tubes, and most frequently at points where the groups of tubes separate from the

main bundle (Pl. 25. figs. 10 & 12). Nearing the body-wall of the posterior segment the

groups become separated entirely into individual tubes (without sheath), which in their

turn branch until, becoming excessively fine threads, they become attached to the

inner surface of the body-wall, where they form an apparently web-like covering.

Entangled amongst these fine tubules, corpuscles of the body-cavity fluid (‘ blood”’)

occur in large numbers (PI. 25. figs. 138 & 14, corp.).

The whole of this region appears to be an exceedingly complex respiratory structure.

The blood on its way to the dorsal vessel in this region, which it enters through a

posterior orifice—through which the strongest inflow seems to occur,—must necessarily

circulate amongst these fine air-tubes, and probably here occurs some of the gaseous

exchange.

The two stigmatic chambers are connected together by a loop tracheal tube with

teenidia, which branches from the inner side of each pit about halfway forward,

and curving ventralwards, meets its fellow in the middle line. From this loop-tube two

branches arise, pass ventralwards and forwards to supply the hindmost pair of blood-

gills. The anterior and smaller pairs of blood-gills receive their tracheal supply from a

ventral branch arising at the anterior end of each stigmatic pit. Hence the whole

tracheal supply to this respiratory region arises either directly or indirectly from the

stigmatic chambers, where one may suppose the air to be most completely renewed.

The ventral processes or “ blood-gills” (Pls. 24 & 26. figs. 2, 3, 4, & 18) are hollow tube-

like outgrowths of the body-wall. They are divided longitudinally into two channels by

a fine membrane-like partition supported by the large air-tube which traverses the —

structure. The blood flowing backwards along the ventral sinus of the body, circulates

THE LARVA OF TIPULA MAXIMA. 129

through these gills, flowing outwards along one channel and returning along the other,

whence it passes dorsalwards to enter the dorsal vessel through its posterior opeving.

The flow through these gills can be distinctly observed in the young larva, when it

is seen to be intermittent, following the pulsation of the dorsal vessel.

Blood-gills are also described by Fr. Miiller as occurring in larvee of Trichoptera as

eversible finger-like tubules, into which the blood flows. They do not generally possess

a tracheal network, but occasionally very fine tracheal branches enter. Pictet describes

them in pupz of Caddis-flies, and Schiddte in the larva of Pelobius. They are

present in Chironomus and some other larvee.

Blood-gills differ from tracheal gills found in many aquatic insect-larvee in the

character of the tracheal supply and in the presence of large blood-sinuses. In the case

of tracheal gills probably the exchange occurs directly by diffusion from the water

to the trachez, while in the case of blood-gills the biood itself plays an important part.

G. Gilson, in describing the rectal blood-gills of Odonata (Journ. Linn. Soc., Zool. xxv.

1896, pp. 418-418), shows that, besides the blood-supply, these receive also a tracheal

supply of peculiar character, and suggests that the fresh supply of oxygen is absorbed

from the water through the medium of the protoplasm of the hypodermis of the gill

in which the trachee lie and passed directly to these tracheze, while the carbonic acid

is brought to the gill through the medium of the blood-flow and directly diffused to the

outer medium without any intermediate passage through the air-tubes.

In the larva under consideration, the structure of the parts involved also points

to the conclusion that both the blood and the tracheal system play important parts in

the exchange of gases, and could Gilson’s suggestion be proved to be correct, it would

throw a flood of light on this difficult question.

The triangular processes (Pl. 24. figs. 4 & 5) which enclose the area around the

spiracles bear along their free margins rows of stiff flattened hairs, those nearest

the apex being larger. When the processes are drawn together, an air-bubble is enclosed

and held by the bristle-like arrangement. The closing, however, does not invariably

occur when the animal is submerged. The fenestrated arrangement of the covers of the

‘spiracles will prevent the entrance of water into the air-tubes, while the blood-gills

probably serve for respiration when the animal is submerged. At the apex of each dorsal

process, and within the fringe, a specially long sensory hair takes its origin (Pl. 24.

fig. 5, s.4.). It is articulated to its base of origin, so that its direction can be varied.

Their exact function was not decided. They appear to be sensitive to touch, but on

stimulating them the flaps were not invariably retracted. Perhaps they may serve to

indicate the necessity for folding the processes on submergence.

Three other sensory hairs of different form also occur—one median, between the

above-mentioned one and the fringe, and two lateral ones, all within the area of the

fringe. They are somewhat shorter than the fringing-hairs and arise from a knob-like

articulation (Pl. 24. fig. 5 a).

The arrangement of the chief dorsal branches of the tracheal system is shown in

Pl, 27. fig. 19.

130 MR. J. M. BROWN ON THE ANATOMY OF

Reviewing the system in the larva of T. maxima, we notice :—

1. An extensive system of fine air-tubes taking origin from the stigmatic chambers

and radiating to the body-wall. Amongst these tubules the blood circulates. It may be

suggested that this is an adaptation for bringing the blood into relation with the air near

to the spiracles themselves.

2. The presence of blood-gills for respiration when submerged.

In the terrestrial form T. oleracea—(1) The spiracle structure and disposition of

air-tubes agree with the above, the stigmatic chambers being, however, shorter. The

same necessity for the arrangement exists here as in the above.

(2) Blood-gills are not developed.

In an undetermined aquatic form, which, however, appears like T. eluta (see

Pl. 26. figs. 21 & 22).—1. A pair of spiracles occur on the posterior face of the

hind segment, asin 7. maxima. They also open into a stigmatic chamber leading into

the longitudinal air-tubes. There is, however, a difference in construction. The cover

of the spiracle consists of a solid conical plug of chitin which fits into the spiracle and

projects downwards into the chamber like a stopper, but leaves a comparatively narrow

border on all sides. This is supported from the rim of the spiracle by a single narrow

circlet of chitinous props, consisting of very short radial bars separated from each other

by narrow slits (like the outer radial bars in 7. maxima). 'These are supported directly

by upright pillars without the intervention of Y-pieces (Pl. 26. fig. 22). Thus we have

avery narrow border to the spiracle, through which air can enter. Further, the filtering-

hairs, arising from the chitinous lining to the chamber, traverse the distance between

the wall and stopper and unite the’ one with the other. Side branch threads occur

forming an efficient filter which would prevent the entrance of water. (A very similar

structure is described in the larva of Dicranota bimaculata by Miall.) No bunches

of air-tubes pass from this chamber to the body-wall. This part of the system appears

therefore simplified. 2. The ventral blood-gills are, however, much more strongly

developed, and, as the creature is usually submerged, will play a more important part in

respiration.

Circulation.

The dorsal vessel, or “heart” (Pl. 27. fig. 19, 4.), occupies the usual position in the

mid-dorsal line of the body. The chambered portion extends from the 4th segment to

the 11th (hindmost), and includes eight chambers. Anteriorly it is continued asa narrow

uniform tube (‘‘aorta”’) as far as the cerebral ganglia. The dorsal vessel lies imme- —

diately upon, and is organically connected with, the muscular pericardial diaphragm.

In certain parts the wall of the heart and the diaphragm cannot be distinguished from q

each other. The heart is further supported by branches of the tracheal system. The

diaphragm (Pl. 27. fig. 19, d.) extends from the posterior segment as far forwards as the |

middle of the fourth. It is supported from the body-wall by the alary muscles, which

are attached not only at the junctions between segments but also at the middle of each

segment. In the posterior segment the diaphragm turns ventralwards, and serves to

cut off the posterior region as a special sinus.

THE LARVA OF TIPULA MAXIMA. 131

Wall of “heart” (see Pl. 26. figs. 20a & 20 6).—Sections of the dorsal vessel show the

following layers :—

1. A middle layer of circular striated muscle (a). This appears to form a continuous

layer throughout the contractile region, though it is generally described as interrupted

at intervals.

2. An elastic fibrous layer (2) on the outer and inner sides of the muscle-layer. Very

large spindle-shaped nuclei(.) occur at intervals in these layers.

3. The surface (“cuticle ’’) of these last layers (c) appears to be distinctly differentiated

from the inner portions, taking stains more deeply. Owing to contraction of the

dorsal vessel these outer layers generally appear raised into irregular ridges. On the

outside of the heart, and running in a longitudinal direction, a number of deeply staining

fibrils (f.) occur. These are branches of the tracheal system, but it is difficult to deter-

mine whether they possess any lumen or not; they certainly appear to be solid. In

transverse sections these longitudinal tracheal threads appear to be supported at the

summits of outstanding projections of the outer (‘‘ cuticle’) layer, giving the appearance

of short pegs capped bya slight enlargement and deeply stained. Upon these the

pericardial cells (p.c.) generally rest, so that they appear to be supported by short props

_ outstanding from the wall of the heart.

Kowalewsky describes the pericardial cells as being attached to the heart by short

muscular props. They do not, however, appear in this case to be muscular.

The surface view of the wall of the heart shows fine cross-striations running obliquely

round the vessel. ‘Two series of striations cross in opposite directions. These striations

are not continuous throughout the length of the vessel, but occur interrupted at regular

intervals. This, perhaps, has some meaning with reference to the observation made

above that the muscle-layer is generally described as interrupted at regular intervals.

The large binucleated pericardial cells (mentioned above, but described in detail below)

are irregularly arranged as a loose tissue on the outer surface of the heart, while a few

occur also on the inner side (Pl. 26. fig. 20, p.c.'). They generally appear to be more

_ or less in longitudinal rows, and bound together partly by the tracheal threads.

Valves.

1. The intersegmental (inlerventricular) valves (Pl. 26. fig. 15, v.2.) occur as paired

lateral thickenings of the inner fibrous layer of the heart, and project inwards and

slightly forwards, and are of such size that during the contraction of the vessel they

meet in the mid line. In structure each appears to be of fibrous substance—an enlarge-

ment of the inner fibrous intima—with a pair of large nuclei at its base, and numerous

nucleated cells (which have the appearance of pericardial cells) embedded in or arranged

on the surface.

There seem to be no muscles in connection with these valves, and from observation

of living animals they appear to work automatically, being forced slightly backwards,

and hence closing, during the contraction of the segment immediately in front.

2. The ostial valves (Pl. 26. figs. 15, v.o., & 16) occur immediately posterior to the

132 MR. J. M. BROWN ON THE ANATOMY OF

above. They appear as pocket- or pouch-like expansions of the wall of the heart, a

median almost vertical slit (0.) occurring in the centre of the pouch. During pulsations

these pockets are alternately turned inwards (7. e. projecting into the lumen of the heart)

when the valves are open, and outwards when the valves close. At the free edges of

the slit the outer (cuticle) layer is thickened, but otherwise they possess no special —

structure. The margins of the pouches are, however, supported by strands from the

diaphragm. No special opening or closing muscles could be detected, and their action

also appears to be automatic, depending on the movements of the heart-wall and on the

external and internal blood-pressure.

The pericardial diaphragm is in structure much like the wall of the heart.

It consists of a base of striated muscle in the form of fan-shaped bands, converging

to the point of attachment to the lateral body-wall (alary muscles). In the middle line

they spread out and serve as supports to the heart, with which they are in places in

connection. They further give support to the transparent fibrous membrane, which is

overlaid by the loose tissue formed by the “pericardial cells.’ These are of peculiar

form. Their shape is variable, but generally irregular, with outstretching processes by

which one cell becomes associated with its neighbours. Many of these processes become

long and thread-like. Fine branches of the tracheal system occur amongst the cells in

jarge numbers. Each cell has generally two large and prominent nuclei, Often the

cells present the appearance of vacuolization.

The pericardial cells occur (1) on the surfaces of the diaphragm, (2) on the surfaces

of the heart.

The function of the pericardial cells, which differ in structure absolutely from the

fat-body, seems to be, largely at least, excretory.

Animals injected with carmine powder, and left for a period and then fixed, showed

the pericardial cells laden with fine granules of carmine. This was seen both in the

pericardial cells on the wall of the heart, and in those on the pericardium itself. The

presence of numerous tracheal branches also suggests an excretory function *.

The posterior end of heart.—In most insects the dorsal vessel ends blindly, butin this

case it is not so. In the hindmost body-segment the heart becomes deeper from the

dorsal to the ventral side, and so forms a much enlarged posterior chamber. The hind

face of this opens backwards by means of a vertical slit, the edges of the slit folding

inwards and acting asa valve. During pulsation an exceptionally strong flow of fluid

enters through this opening and plays an important part in “sucking” the blood

through the posterior respiratory region of the body.

Pulsations of the Heart.

During pulsation a gradual wave of contraction passes along the dorsal vessel from

behind forwards.

* Kowalewsky states that the carmine is absorbed by the leucocytes and passed on by these to the pericardial

cells after solution, the pericardial cells themselves being unable to ingest. My preparations did not, however,

show the leucocytes containing carmine, but the pericardial cells were everywhere crowded with minute particles,

as were the cells of the Malpighian tubes.

THE LARVA OF TIPULA MAXIMA. 1383

Taking any one point of the heart, the pulsation may be said to include four

phases :—

(a) The resting position, during which the heart is expanded to its normal diameter

and the blood is streaming rapidly forward. As the pressure from behind increases, or

perhaps as the resistance in front increases, the second phase is reached.

(0) A slight expansion occurs, due to the stretching of the elastic walls by the rapid

increase in internal pressure. This is followed at once by

(ec) A forceful and sudden contraction, which drives the contained blood forward, a

back flow being prevented by the closing of the intersegmental valves. After a slight

pause,

(d) finally a recovery by expansion to the original position of rest, in which phase

(z. e. rest) the heart remains for a period equal to about half the total period.

Movements of Ostial Valves.

During the pulsation of the vessel the ostial valves pass through a regular succession

of movements.

(a) During the resting phase (a, above) the valves are open, é. e. the pouch is bulged

inwards, and blood is entering in a steady stream and joins the forward flow in the

heart. They remain in this position until the heart expands (d, above), when they

suddenly bulge outwards and close. This movement does not appear to be due to

muscular movement of the valve, but to be the result of the increase in internal

pressure.

During contraction (ce, above) they are closed, and the blood is flowing forward

through the intersegmental valve to the chamber in front.

The moment the heart relaxes and begins to expand (d, above) the relief of pressure

within causes the ostial pouch once more to suddenly invert, and the valve opens and

blood enters and joins the forward flow.

Blood returns posteriorly along the ventral sinus and also along each side of the

heart in the pericardial sinus, some entering the heart at the ostia. No signs of any

LSS Ss, le rh

special flow into the pericardial sinus through the diaphragm could be detected.

In the posterior segment of the body the periodic rush and stoppage of the blood

is well seen. The movement here appears largely due to the suction exerted by

the expansion of the posterior chamber of the heart and the opening of the posterior

ostium.

The blood-flow throughout the body is intermittent, and synchronous with the

pulsations of the dorsal vessel.

On the average, a pulsation occupies 2°5 seconds, or at the rate of about 24 per minute,

the resting phase occupying about half the whole period.

During the pulsations of the heart no regular and corresponding elevation and

depression of the diaphragm could be observed, and, at any rate in this larva, I am

inclined to believe that its chief function is that of support, and that it plays no part,

or very little, in the directive action on the blood-flow.

VIII. Three Species of Harpactid Copepoda.

By Canon A. M. Norman, Jf.4., D.C.L., LL.D., F.RS., FL.S.

(Plates 28-30.)

Read 16th February, 1911.

THE following three species of Crustacea were found in 1888, in the Firth of Clyde,

when I was with Sir John Murray in his yacht. The Zaophonte was dredged in

Lamlash Bay. Ancorabolus and Arthropsyllus were found under somewhat peculiar

circumstances. It was blowing hard, and we ran for shelter under the north-east

corner of the island of Little Cumbrae. The dredge was let down in about 20 fathoms,

and came up full of broken and decaying seaweed, among which nothing could be seen.

However, I worked a portion through sieves, but there was scarcely any product.

Nevertheless, among the very few things were found the two species just mentioned

and Campylaspis costata, G. O. Sars—all three additions to the British fauna.

The Ancorabolus surpasses all known Crustacea in its wonderful ornamental sculpture,

with the exception of Pontostratiotes abyssicola, G. 8. Brady, procured by the ‘Challenger’

Expedition at the great depth of 2200 fathoms in lat. 37° 29’S., long. 27° 31’ W, When

Ancorabolus was found it was almost smothered by fragments of filamentous algze which

clung to it.

The drawings here published were kindly made for me by Mr. Andrew Scott in 1890,

but the pressure of various work has compelled me to defer publication.

Genus Laopnonts, Philippi.

LAOPHONTE BULBIFERA, sp.n. (Pl. 28. figs. 1-7.)

Animal with head rather broad, thence tapering gradually backwards to the caudal

rami. Head as broad as long; rostrum well produced, obtuse, terminating in two minute

cilia. 2nd and 3rd segments of urosome produced outwards and backwards, terminating

in a minute spine. Whole animal densely pubescent.

Caudal rami remarkable on account of their bulbous form; they are as broad as long

and scarcely equal in length to the preceding segment. Principal seta long, equal to

_ the whole length of the animal; exterior to this is a second long seta, which, together

with four small sete, terminate the ramus.

Anterior antenne 6-jointed and slender for the genus; their basal joint short, with

two small projections on the outer margin; 2nd joint twice as long; 3rd rather shorter

than the 2nd; 4th and 5th very short, last joint equal to the two preceding.

Posterior antenne unusually slender for the genus; outer ramus well developed and

slender ; inner ramus slender, terminating in four setz.

SECOND SERIES.—ZOOLOGY, VOL. XI. 21

1388 CANON A. M. NORMAN ON

2nd maxillipeds with the hand narrow elongated ovate; claw long and very slender.

1st feet having the 2nd basal joint narrow and fully twice as long as broad. Inner

ramus is slender throughout, 1st articulation has both margins setose; outer ramus is

2-jointed, the 1st with a single seta on the outer margin and the 2nd with five.

4th feet having inner ramus less than half the outer, scarcely exceeding the 1st joint

of the outer in length ; its 1st joint has one interior seta and the 2nd carries five setz.

5th feet having an inner expansion of the 1st joint bearing two sete, and nearer the

attachment another seta. The outer lobe of the basal joint bears the usual seta. The

2nd joint is remarkable, as compared with other species of the genus, for its great length,

being six times as long as broad, and is furnished with two sete at its outer base, three

sete towards the termination, and terminates in a simple seta.

Size ‘8 mm.

The specimen here described was dredged in Lamlash Bay, in the Firth of Clyde, ing

July 1885.

The species is characterized, first, by its 6-jointed antennz ; second, by the outer

branch of the 1st feet consisting of only two joints; third, by the peculiar form of the

bulbous caudal rami; fourth, by the structure of the 5th feet. This peculiar 5th foot

finds its counterpart in Laophonte elongata, Boeck, and Laophonte typhlops, G. O. Sars.

Family ANCORABOLIDA, G. O. Sars.

** Body slender, tapering behind, with no sharply marked boundary between the

—_—

anterior and posterior divisions. All the segments very sharply defined and, excepting —

the last 2 or 38, produced to peculiar horn-like projections, either dorsal or lateral, or —

both dorsal and lateral; cephalic segment somewhat flattened in front, with the antero-

lateral corners generally produced ; rostral projection of varying shape in the different

genera, in some cases wanting. Genital segment imperfectly subdivided in female.

Caudal rami long and slender, with one of the apical setee much elongated. Eye wholly

absent. Anterior antennz with the number of joints much reduced, terminal part (in

female) uniarticulate. Posterior antennee without any trace of an outer ramus. Oral

parts poorly developed, but, on the whole, of normal structure. Natatory legs slender

and projecting more or less laterally, 2nd basal joint obliquely produced; 1st pair

generally differing in structure from the others, but never prehensile. Last pair of legs

with the distal joint long and slender, proximal joint generally produced outside to a

long narrow process tipped with a slender bristle. A single ovisac present in the female.”

The above is Sars’s description of the family which he has created. In it he has placed

four genera, each of a single species. Of these I was previously acquainted with two— ~

Ancorabolus and Arthropsyllus. It is this latter genus which in my description of

Ancorabolus I mentioned as “a second species” of the same genus taken at the same

time as Ancorabolus mirabilis.

The most remarkable character appears to consist in the form of the feet, which

have the second basal joint produced outwards to a considerable extent, so that the

attachments of the two branches are a considerable distance apart, and the inner branch

THREE SPECIES OF HARPACTID COPEPODA. 1389

is much smaller than the outer. In this respect the family approaches Laophontodes,

save that the Ist pair of that genus resembles that of Zaophonte. Moreover, the form

of the Ist and 2nd antennee and of the 5th feet, as well as the transformed branch of

the 3rd feet of the male, shows strong resemblances. As Sars remarks, the structure

of the 1st feet more nearly resembles that of the genus Cletodes, which undoubtedly

shows other alliances.

Genus ANncoraBoLus, Norman.

“Body armed with numerous horn-like, partly branched processes curving backwards,

and forming several rows, dorsal, subdorsal, and lateral. Rostral projection well defined,

narrow linear. Anterior antennz in female composed of only 8 joints, in male

5-articulate and distinctly hinged. Posterior antennze with the distal joint very slender,

linear. Mandibular palp small, uniarticulate. Posterior maxillipeds very slender.

Ist pair of legs differing conspicuously in structure from the succeeding ones; both

rami biarticulate, the inner one being the longer. Inner ramus of the three succeeding

pairs much smaller than the outer, but distinctly biarticulate. 1st joint very short,

2nd narrow linear ; outer ramus slender, 3-articulate. Inner ramus of 2nd pairs of legs

in male slightly transformed. Last pair of legs with a well-defined setiferous expansion

inside the proximal joint, wanting, however, in male.”

Such are the characters which Sars assigns to the genus as restricted. That author

has changed my spelling of Ancorabolus to Anchorabolus. Why? ‘The generic name

is derived from ay«ipa and PaddAw (an anchor-caster) and the Latin form is Ancora

(more rarely Anchora).

1909. Anchorabolus mirabilis, G. O. Sars, Crustacea of Norway, vol. v. Copepoda, Harpacticoida,

p- 312, pl. 211.

Rostrum well developed, horizontally directed, cleft at the extremity, bearing one or

two pairs of setz on the sides, situated on little protuberances. Cephalon and four

following segments ornamented with a wonderful series of simple furcate, and three-

branched large horn-like processes, which are arranged as follows :—The cephalon bears

two pairs of backward-directed horn-like processes on the back: the anterior pair are

simple, the posterior trifid. The margin of the cephalon bears, first, a simple lancet-

shaped spine followed by a larger trifid process, followed by a bifid, and posterior to this

a trifid process. These are all of large size. The following four segments have a pair

of simple dorsal processes, beneath which are subdorsal processes, which on the three

earlier segments are bifid, but on the last of larger size and simple. On the lateral

margin are very large falcate processes, curving backwards. The three earlier segments

of the urosome are furnished with subdorsal simple and lateral processes. These lateral

processes gradually increase in size backwards from the head to the 3rd segment of the

21*

140 CANON A. M. NORMAN ON

urosome, where they are subequal in length to the breadth of the body. All the

processes described have the outer margin ciliated. Last segment of urosome is rather

more than half the length of the preceding. The caudal rami are very long and slender,

equal in length to two and a half preceding segments, bearing on the middle of the outer

margin a spinule, and at the extremity four minute spines, and centrally a very long

spine, so that the whole length of the ramus is as long as the whole of the rest of the

body.

The 1st antenne are 3-jointed and slender. The 1st joint has at the extremity of the

lower margin a small denticulation, and in some specimens there is also a small curved

process near the commencement on the outer side of the 2nd joint. The posterior

antenne are 2-jointed, devoid of a secondary branch, slender, and 2nd joint longer than

the Ist. Hinder mawillipeds very slender and long, nearly parallel-sided; nail very

long and slender. Zhe legs are all remarkable from the 2nd basal joint being produced

outwards to a considerable extent, so that the attachment of the inner branch is far

removed from that of the outer. 1st pair has the inner branch twice the length of the

outer; its basal joint is without setee, 2nd joint terminates in three setee. The outer

branch has the Ist joint rather more than half the length of the 2nd, and bears one seta

on the outer margin; the 2nd joint has two sete on the outer side and three terminal.

In the 2nd, 8rd, and 4th pairs the inner ramus is very much shorter than the outer and

terminates in two or three setze. Its 1st joint is not more than one-third or one-fourth the

length of the 2nd. Zhe 5th pair has the outer limb very long and linear, more than six

times as long as broad, and carries two setze on the outer margin, one on the inner and

two terminal. The simple seta of the exterior margin of the basal joint is of great size.

The inner lobe of the basal joint is long and slender, about equal to half of the outer

joint ; it is furnished with two setz on the inner margin and two apical.

Length of female ‘8 mm.

The male I have not seen. Sars describes it as “smaller than female, and with the —

anterior antenne distinctly hinged, 5-articulate, 3rd joint slightly dilated, last joint

claw-like. Inner ramus of 2nd pair of legs armed at the tip with a somewhat flexuous

claw-like spine in addition to the sete. Last pair of legs much smaller than in female, —

one of the sete wanting on the outer side of distal joint, proximal joint without any

expansion inside.”

This species was first dredged by me in the Firth of Clyde, in 1888, among a mass of

decaying weeds on the east side of Little Cumbrae. In 1890 1 again met with it in the

Varanger Fiord in East Finmark, and Sars has met with it in several places on the

Norwegian coast.

Genus ARTHROPSYLLUS, G. O. Sars.

Body flanked each side with a series of acutely produced lappets arising from the

lateral parts of all segments except the last two. Cephalic segment with a broadly

triangular rostral projection, antero-lateral corners rounded off. Antennules in female

3-jointed, those of male strongly hinged. Antenne somewhat robust. Legs with

THREE SPECIES OF HARPACTID COPEPODA. 141

2nd basal joint less produced outwards than in Ancorabolus. 1st pair with both rami

2-jointed and subequal in size. Inner ramus of three following pairs well developed,

2-jointed, shorter than the outer. Last pair of legs very similar in character to those

of Ancorabolus. 2nd pair of legs in male armed at the tip of the inner branch with a

curved spine of considerable size.

ARTHROPSYLLUS SERRATUS, G. O. Sars, var. SPINIFERA, Norman. (Pl. 80. figs. 1-14.)

1909. Arthropsyllus serratus, G. O. Sars, Crustacea of Norway, vol. v. Copepoda, Harpacticoida,

p- 318, pl. 214. f

Body depressed ; head broadest, thence gradually tapering backwards ; segments well

marked. Cephalon broad, about as broad as long ; rostrum widely rounded and slightly

prominent ; lateral margins of cephalon slightly notched behind the rostrum, followed

_by three lateral lobes, of which the middle one is the shortest and the posterior armed

with a spine. Segments of the body and first three of the urosome armed with large,

faleate, sharply-pointed lateral processes. The body-segments and two earlier segments

of the urosome furnished posteriorly with four small spines. The 3rd segment of the

urosome hears only two such spines. ‘The last two segments of the urosome subequal,

the terminal being rather shorter. Caudal rami subequal in length to three segments

of the urosome, bearing two spines on the outer margin, three small terminal, and the

long final seta which, together with the rami, equals the length of the entire animal

except the head.

Anterior antenne 3-jointed, moderately stout and long; joints nearly equal, bearing

_ numerous spines.

Posterior antenne consisting of two equal joints and entirely devoid of a secondary

branch ; the 1st joint with two sete on the outer margin, the 2nd with two spines on the

inner margin, and terminating with five sete.

Posterior maxillipeds with the hand elongately ovate, terminal claw unusually long

and slender.

1st feet with two branches subequal in length and 2-jointed ; inner ramus terminating

in two long sete, outer with one seta on the Ist joint, two on the 2nd, and three at the

extremity. Succeeding feet with the outer ramus 38-jointed, and the inner is much

‘shorter than the outer, 2-jointed, the 1st joint very short. The setose armature is

nearly similar to that of the 1st pair, except that the 2nd joint of the exterior branch

carries a long seta on its inner face.

The 5th feet have the outer branch long and narrow, five or six times as long as

broad, with two setz on the outer margin and three terminal, of which the central is

‘much the longest. The basal joint has the interior produced lobe with four sete, and

is about half the length of the terminal joint.

Length ‘7 wm.

Male with antennules very stout, 6- or 7-jointed; 3rd joint greatly swollen, terminal

strong, nail-like.

142 CANON A. M. NORMAN ON

2nd foot with the inner branch bearing a strong, curved spine-process and two long

sete.

5th feet of nearly the same structure as those of the female, but very much shorter.

This species was dredged, in company with Ancorabolus mirabilis, on the east side of

Little Cumbrae, in the Firth of Clyde, in 1888. Sars has found it in the outer part of

the Trondhjem Fiord and other places in Norway, and records a specimen taken by

Mr. Nordgaard at Repvaag in East Finmark.

In my description of Ancorabolus I referred to this form as a second species of that

genus. I feel considerable difficulty with respect to the description I have given. In

its structural details it seems to agree closely with Sars’s species, but in the drawing

which I publish it will be seen that the segments are armed with spines. These are

not noted by Sars. The drawing was made for me by Mr. A. Scott in 1890, who is

extremely accurate. In my specimens now mounted I am unable to see, in consequence ~

of the opacity of the animal, the spines referred to. I thought it was better, therefore,

to give it a varietal name, which can hereafter be used as specific if the form should —

prove to be distinct from that described by Sars.

IX. Dermaptera (Earwigs) preserved in Amber, from Prussia.

By Matcotm Burr, W7.A., D.Se., F.LS., F.ZS., FES.

(Plate 31.)

Read 2nd March, 1911.

Turouci the kindness of the late Dr. Klebs, of Kénigsberg, who possessed the finest

_ collection in existence of insects in amber, I have had the privilege of examining the

earwigs that have been thus preserved. The Director of the Berlin Natural History

Museum has also very kindly communicated to me the species in his charge for purposes

of comparison and examination.

A good number are immature, having the essential characters feebly developed, but

there are mature males of four distinct and well-defined species. These are, on the

whole, exceedingly well preserved, but it is very irritating when the important features

are obscured by the opaque white material and waviness noted by Mr. Shelford in his

paper on the cockroaches in amber (J. Linn. Soc., Zool. xxx. p. 336, 1910).

Tn all these four species the tarsi have the second segment more or less dilated, and

_ therefore they must be referred to the family Forficulide in the strict sense. But some

of them have distinct keels along the shoulder of the elytra, a feature which in this

family is confined to certain genera of the Ancistrogastrinee and Opisthocosmiine, with

which these fossil species have no near relation. In other respects, as the cylindrical

_ branches of the forceps, some of these specimens differ from the typical genus Forficula,

_ although one at least cannot be generically separated from Forficula auricularia, L.

Properly speaking, therefore, a new gents should be erected for the others, as they fall

into no genus at present existing; but I hesitate to base new genera upon such relatively

_ meagre material, and prefer to range them all in Forficula, using that name in the

_ comprehensive old-fashioned sense.

When this particular family has been once more revised and reduced to a better

system, it may be possible to range these fossil species in genera that may be required

- for existing forms.

_ he first feature that strikes the observer of these specimens is their up-to-date

appearance. There is nothing archaic or old-fashioned about them, and although I am

unable to find in them close relationship with any known forms, there is nothing to

_ suggest that these very creatures may not yet be discovered.

Forficula precursor, for instance, is very much like some known Oriental and

5, Ethiopian species, while the forceps and pygidium of P. klebsi closely resemble those of

- Nala Jiginti, Burr, from Eritrea. The coloration, so far as can be detected, the

general appearance, and especially the keels of the elytra of FP. baltica and F. pristina

SECOND SERIES.—ZOOLOGY, VOL. XI. 22

146 DR. M. BURR ON DERMAPTERA

are very suggestive of the genus Wala, but the lobed second tarsal segment at

once excludes them from the family Labiduridse: in /. baltica the dilation is very

feeble, as may be seen from the figure, but it is enough to forbid the inclusion of the

species in the Labiduride.

The specimens are all in Baltic amber, which is commonly attributed to the Lower

Oligocene age.

PRESERVED IN AMBER, FROM PRUSSIA. 147

Of this species there is a single male in the Simon Collection of the Berlin Museum.

It is very well preserved, as may be seen from the figure, and the texture and

pubescence may be easily distinguished. The colour is very dark, only relieved by the

smooth transverse bands along the posterior margins of the abdominal segments, which

are much paler.

The second tarsal segment is but feebly dilated, but possibly the lobe is produced

beneath the third sufficiently to warrant its inclusion in the Chelisochinz, a position

which would be justified by its general appearance, which, like the size and type of

forceps, recalls that of Proreus melanocephalus, Dohrn, an Oriental species with which

it might well claim relationship.

It is not possible to be certain as to the existence of the keel of the elytra, but there

seems to be one: this feature is rare in the Chelisochine and does not occur in Proreus.

males in the Klebs Collection (Nos. 2729 and 4181: the former is the type).

22*

148 DR. M. BURR ON DERMAPTERA

The tarsi are visible in No, 4181, as may be seen in the figure; they are typically

forficuline.

In No. 2729 there are a pair of firm globular bodies situated so symmetrically on the

second and third abdominal segments that they look like organs, but in No. 4181, which

has a similar pair, it is evident that they are not similarly disposed, and in the Simon

specimen there are none: I think they are probably Acari preserved in the amber.

The female which I attribute to this species is in a bad state of preservation; but it is

interesting to note that it holds a small insect, apparently Dipterous, in its forceps: the

dorsal surface is entirely obscured by the cloud of the opaque white substance, and only

a profile view is possible; the inside of the creature has been eaten away, leaving the

empty shell.

The Simon Collection contains a larva which may be referable here: the second tarsal

segment is narrow, but, when seen from the side, lobed, which is suggestive of Cheliso-

chine relationship ; the forceps show no trace of segmentation; the antenne are thick,

with seven segments discernible.

dilated forceps are characteristic of the genus Forficula, but I cannot prevail upon

myself to erect a new genus for this species, in spite of a strong resemblance to the small

the same general resemblance, but the strongly dilated second tarsal segment proves

them to belong to the true Forficulids and not to the Labiduride.

1. IntRopUcTORY REMARKS.

Tue Nemopteridee form a small specialised group of insects usually classified as a sub-

family of the Neuropterous family Hemerobiide. Only a small number of species have

been described up to the present, and their most striking characteristic is seen in the

enormously elongated and filiform hind wings, which project for a long distance beyond

the apex of the abdomen. Scarcely anything has been recorded concerning either the

habits or life-histories of these remarkable insects, and the present paper is offered as a

small contribution towards a knowledge of the bionomics of the common Indian species

Croce filipennis, Westw.

Many years ago Roux* figured a remarkable larva with an immensely long and

attenuated neck, and a rounded head bearing a pair of large prominent mandibles. It

occurred among accumulated sand in the tombs and pyramids of Egypt, and he regarded

it as-a fully matured insect, and described it as such under the name of Necrophilus

arenarius. Westwood +, in 1840, pointed out that it appeared in reality to be the larva

of a Neuropterous insect, and suggested that it might possibly belong to the Nemopteridz.

According to Longinos Navas f{, in his recent monograph of the Nemopteridz, Schaum §

also believed that Necrophilus arenarius was a larval form belonging to this subfamily.

Sharp * also holds a similar view as regards its affinities. Last year Lefroy ¢ obtained

some eggs from a captive female of Croce filipennis, which hatched out into small white

larvee, of the same form as that represented in Rowx’s figure, except without the greatly

elongated neck. Jam not aware that anything further has been contributed towards a

knowledge of the life-history of the Nemopteride.

Croce filipennis was originally described by Westwood { under the title of Nematoptera

Jilipennis as follows :—

“Nem. luteo-fusca; alis anticis albo-hyalinis; stigmate fusco; posticis longissimis,

basi nigricantibus latioribus; apice albo filiformi. Long. corp. lin. 3}. Expans. alar.

antic. lin. 113. Long. alar. postic. 1 une. 3 lin. Habitat in India orientali. In Mus.

D. W. W. Saunders, F.L.S., &e.”

In 1847 Westwood § refers to it as Nemoptera filipennis and describes it as follows :—

** Nemoptera subfulva antennis fuscis, alis anticis hyalinis stigmate fusco, alis posticis

longissimis filiformibus dimidio basali fusco apice albo.

*‘ Nemoptera dull fulvous coloured, antennze brown, fore wings hyaline iridescent, with

a pale brown stigma, hind wings very long, thread-like, the basal half brown, the

extremity white Expansion of the fore wings nearly 1 inch. Length of the hind wings

1+ inch.

* Tnhabits Central India. In the collections of Col. Hearsey and Mr. Hope.”

In 1885 M‘Lachlan || proposed the new generic name Croce for a group of the

Nemopteridz comprising species usually of small size. They are characterised by the

front being very strongly produced into a slender beak, by short antennee (which are

usually somewhat thickened towards the apex), by transparent anterior wings with very

open neuration and usually with a strongly defined pterostigmatic mark, and especially

by long setaceous posterior wings, strongly ciliated, in which even the rudiments of

neuration are scarcely to be traced. Croce filipennis is taken as the type of the genus.

2. THE DISTRIBUTION AND Hasits oF THE IMAGO.

’ Croce filipennis appears to be the commonest and most widely distributed species of

the Nemopteridze found in India. Through the courtesy of Dr. N. Annandale I have

been able to examine the specimens in the collection of the Indian Museum, Calcutta.

It contains three species of the subfamily, and these have been recently reported on by

Needham 4 :—

1. Croce filipennis occurs around Calcutta (NV. Annandale); Katihar in the Purneah

District (C. A. Paiva); Surat and Igatpuri, Bombay (Lefroy Collection) ; and Allahabad

(A. D. Inms).

Bushire, Persian Gulf (JV. D. Cumming) *.

3. Halter halterata, Forsk., is represented by a series of specimens from North

Baluchistan (Dr. Maynard).

In the neighbourhood of Allahabad I have observed Croce filipennis during the last

three years. It is on the wing from the end of March to the end of April. The earliest

date I have observed it was March 28th, and the latest April 24th. From about

April 3rd to April 16th it attains its greatest abundance. I have seldom noticed it out

of doors; the most usual situation for finding it is in the rooms of bungalows, outhouses,

&e., where the larval life is spent. It avoids the sun when flying and is principally

crepuscular in habits. It commences to fly about half an hour to one hour before sun-

set, though in dull corners where there is very little light I have seen it flying at all

times of the day, and at night it is sometimes attracted toa light. It is a feeble flier

and examples can be caught with ease. They have a habit of three or four individuals

flying closely together in a group, occasionally for half an hour or more at a time. They

soar up and down after the manner of the Ephemeridz, and keep to a narrow confined

area often for some considerable time. Most likely the habit is concerned with court-

ship though, in spite of frequent observation, I have not observed the sexes couple.

During flight the thread-like hind wings stream behind the body and are kept

outstretched so as to make an angle of about 60° with one another. When resting the

insect reposes on dark woodwork and other suitable objects, its fore wings are closed

over the back after the manner of those of a butterfly, and the hind wings are extended

backwards, but at a more acute angle with one another than when flying.

3.) Dan) EGGes-

The eggs are oval in shape (PI. 82. fig. 3) with a smooth and glistening surface. There

is a slight variation in the size among different eggs, the length varying from *50—55 mm.,

and the width from °80-—35 mm. ‘Their colour varies from greyish green to a blue-green,

and they are laid singly in nooks and crannies among dust and sand on the floors of

neglected rooms and buildings. The particles of sand adhere to the surface of the eggs,

and the latter become so efficiently concealed by this means that it is almost impossible

to detect them unless the females are confined in a small vessel during oviposition.

Captive females laid eggs freely when placed in glass beakers; they were deposited

apparently at random on the sides and bottom of the vessel.

The table on p. 154 shows the number of eggs laid by captive females, and the time

taken to hatch when kept in a relatively cool room.

The time taken for the larvee to hatch out thus varies between 10 and 12 days. The

young larva escapes from the egg by the separation of an irregular lid-like cap at one

_ end, which remains attached by a portion of the shell.

* Navas has recently described a new species of this genus, NV. meade-waldoi, from Murree in the Himalayas.

4. THE Larva.

A. The young Larva.—The young larva when first hatched is white, with brownish

mandibles, and the eyes appear as a purplish-black spot on either side of the head

(Pl. 32. fig. 2). In thirteen examples the length varied from 1:40-1:77 mm., the average

length being 15 mm. The breadth across the widest part of the body varied from

*35-—42 mm. For the purposes of description, it will be convenient to divide the larva

into three regions, viz.: the head, the neck and the trunk. The head is very slightly

broader than long, the widest part being the region between the eyes; posteriorly it

narrows very considerably. The antero-lateral angles are rounded, and the anterior

border of the head is excavated into a moderately deep sinus; the posterior border is

curved to form a relatively shallow sinus. The eyes are situated on a rounded pro-

tuberance bulging out on each side of the head, and placed just external to the point of

insertion of the antenna of its side. They consist of a group of six or seven pigmented

ocelli on each side. The antennz are somewhat longer than the head, measuring

‘40-42 mm. long. They are ten-jointed ; the basal joint is shallow and annular, and the

second joint stout and wide, the two joints together forming a scape. The flagellum, or

remainder of the antenna, consists of elongate basal and terminal joints, both subequal

in length, and measuring "11-13 mm. long. Between these two joints is an intervening

region composed of six small joints of about equal size. The apical joint of the antenna

is terminated by setze possibly of a sensory nature. The mandibles are rather longer

than the head; they are curved and acuminate, and each is provided with a row of four

teeth along the inside margin of its proximal half. The first tooth is very small (in

some specimens it is wanting altogether), the second large, and the two distal teeth are —

largest of all. The maxille (Pl. 32. fig. 4) are highly modified and closely resemble the —

mandibles in form. In length they equal the mandibles, but they are narrower and are

not provided with teeth. They lie immediately ventral to the mandibles and are closely

applied to a groove on the under surface of the latter. They are not visible from aboye,

LIFE-HISTORY OF CROCE FILIPENNIS. 155

except through the partial transparency of the mandibles. ‘There are no maxillary palpi.

The labium is fused up with the ventral region of the head; a pair of prominent labial

palpi are present (/.p. in fig. 4). The palpi are three-jointed, the terminal joint being

the longest. The joints are related to one another in length as 5:38:11.

The neck consists of two segments, and is a little longer, though much narrower, than

the head. The first segment carries no appendages, but the second segment bears the

first pair of legs, and is consequently to be regarded asthe prothorax. The first division

of the neck is the shorter and narrower of the two and its diameter lessens posteriorly.

The second division of the neck broadens posteriorly and, in addition to its shape and

slightly larger size, it differs from the first segment in its antero-lateral angles being

more prominently rounded.

The trunk is a region of composite nature. It carries the second and third pairs of

legs, and consists of the meso- and metathorax imperfectly demarcated from the abdomen.

The indications of segmentation are a little indistinct, but the abdomen appears to be

composed of ten segments. The legs are long and slender, subequal in length. The

coxa and trochanter are short; the femur, tibia, and tarsus are related respectively to

one another in length as 10:11:6. The tarsus is terminated by a pair of slender

curved claws.

Over the dorsal surface of the body of the larva are distributed curious cuticular

structures, each borne on a small chitinous tubercle with which it is articulated. There

are two types of these structures, one of which is small and lanceolate with entire

margins, and the other larger and dentate. I propose to distinguish them as the lanceo-

late and dentate spines (P1. 32. fig. 5). The lanceolate spines are the less common type

of the two, and are found on the outer border of the mandibles and on the legs. Those

on the tarsi and the apices of the tibiz are slightly longer than the spines that occur

higher up. The two distal teeth of the mandibles each carry laterally a lanceolate spine,

and the two proximal teeth each bear a dentate spine. A number of dentate spines are

scattered over the dorsal surface of the head, and a row of five specially prominent

spines occurs around the base of each mandible. The first segment of the neck carries

a double longitudinal row of dentate spines on each side—a dorsal row of three (or

four) spines and a dorso-lateral row of three. The second neck-segment bears a pair of

dentate spines on its anterior margin—an antero-lateral pair, and a longitudinal dorsal

row of six spines on either side of the middle line. In the trunk-region the dentate

spines are principally arranged in transverse rows and are most numerous posteriorly.

B. The half-grown Larva.—tThe half-grown larva differs from the newly hatched

larva, not only in its much greater size, but also in the body being much flatter and less

convex, in the greater chitinization of the cuticle, in being pigmented, and in the

relatively larger size of the trunk-region.

The head is similar in shape to that of the newly hatched larva, but the mandibles

differ in having usually nine tooth-like projections along their inner edges instead of

four. They are not to be regarded functionally as teeth, for they carry articulated

spines, and, moreover, the manner in which the larva seizes its prey by the tips of its

jaws, and the fact that it feeds on the juices of its prey by means of suction, precludes

156 DR. A. D. IMMS ON THE

the idea of their being regarded as teeth in the ordinary acceptance of the term. It is

difficult to conceive what purpose, if any, they may fulfil. ‘They are perhaps to be

regarded as enlarged and slightly modified papille of the same type as those found on

other parts of the body. ‘The dentate spines are larger and much more numerous than

in the young larva. Jn coloration it is similar to that of the full-grown larva to be

described below.

C. The full-grown Larva.—Examples of the full-grown larva varied in length from

68-72 mm., with a width of 85 mm. across the widest part of the body. The head

and jaws are yellow-brown, the latter being a little darker at their extremities. The

dorsal surface of the head has a granulated appearance produced by the numerous

dentate spines scattered over it (Pl. 32. fig. 3). Between the eyes there isa pair of darker

brown patches, and on them open a pair of chitinous tunnels which are directed into

the head. ach eye-group is placed on a rounded tubercle on either side of the head.

The first segment of the neck is buff-coloured, the second segment is darker and

inclining to brownish towards the base. The ¢érunk-region is light brown, darkening

towards the mid-dorsal line. The brown coloration is disposed in a series of transverse

segmental bands, whose width narrows towards the outer margins of each segment. A

median longitudinal streak of buff-colour runs down the whole length of the trunk-

region, except in the third segment, where it is crossed by the transverse brown band of

that segment. The outer margins of each segment are suffused with buff-colour, and

the buff-coloured longitudinal streak is bisected by a narrow brown line extending from

the fourth to the seventh segment. The terminal papilla-like apical segment of the

body is buff-coloured, and the legs are pale brownish. Ventrally, the head and jaws are

of the same colour as exhibited on the dorsal aspect ; the first segment of the neck and a

large portion of the second segment are buff-coloured, while the rest of the body and

legs are light brown.

The table of measurements on p. 157 shows the relative growth of the different

regions of the body during three periods in the life-history of the larva,

The Habits of the Larva.—A number of larvee in all stages of development were reared

in captivity, and they fed upon Psocids and very young larve of a species of Dermestes ;

they are exclusively carnivorous. The process of feeding was observed under a Zeiss

binocular microscope in the case of a larva confined within a small glass vessel for the

purpose. The prey is seized by the tips of the mandibles and held there until its juices

are completely sucked out by the pumping-action of the pharynx. The maxille (Pl. 32,

_ fig. 4) resemble the mandibles very closely in shape and size, and fit into the underside of

the latter, which is grooved to receive them. An imperfect channel is thus formed by the

mandibles and maxillz on either side, and the juices of the prey were easily observed to

pass down it to the head, and afterwards down the cesophagus in the neck. The neck

is very flexible, and consequently the head has considerable latitude in its movements.

On one occasion I noticed a Psocid crawl on to the back of a Croce larva, and the —

latter bent its head and neck completely over its back with great ease and seized it.

‘The adaptation of the mandibles and maxille to form an imperfect suctorial tube has

been previously observed among other subfamilies of the Hemerobiide, notably by

Meinert * in the larvee of Myrmeleon and Hemerobius. Completely suctorial mandibles

have been described by Schiddte f in the larva of the European Coleopterous insect

Gyrinus marinus, and they have been long known in the larva of Dytiscus marginalis

from the early observations of Swammerdam }{ and later by De Geer, and more recently

by Miall and by Burgess. Gyrinus and Dytiscus differ from the larvee of the

Hemerobiide in that the maxillz are not specially modified, nor do they aid in per-

forming any suctorial function ; but the mandibles are perforated by a minute pore close

to their apices, and this leads into a channel passing through the centre of each mandible

to the mouth.

The larvee frequent disused or neglected rooms and outhouses, living on the floor

among accumulated sand and dust. In such situations Psocids are extremely plentiful,

and I believe that they form their principal prey. In their habitat the larve are well

concealed by a covering of particles of sand and dust. They cover themselves by

pushing the posterior end of the abdomen into the latter, and bury themselves until only

the head remains visible. They afterwards emerge with a coating of such particles, which

are to a large extent kept in position by the numerous dentate spines covering the body.

Thus concealed, the larva remains motionless for long periods, until it may dart forward

_ to seize some prey that may wander in its vicinity. It was a matter of great difficulty

to discover the larvee when the habitat was only suspected and not definitely known.

The first larvee were met with in July 1907, and the most advantageous way of detecting

them was to examine a quantity of sweepings from the floor of a neglected room

spread over a flat open vessel. If tobacco smoke be puffed over the sweepings,

any larvee present may sooner or later be detected moving about.

The most active period of larval life is during the hot weather and subsequent

“rains.” At the end of the latter the greater part of growth has taken place. During

the Indian cold-weather season they are much less active, seldom move unless disturbed,

and only occasionally feed on the Psocids when presented before them. Nearly full-

grown larvee were met with as early as July 25th, eight months further having to elapse

before they pupated. On the other hand, a larva measuring only 3°6 mm. long was found

as late as March 6th—less than a fortnight before they usually commence spinning the

occoon. Possibly in some instances the life-history may occupy a second year. Owing

to my absence from Allahabad this larva died and I was unable to determine the

accuracy of this suggestion.

5. Tue Pourpa.

Towards the middle of March the larvze become full-fed and commence to form their

cocoons. ‘The latter are nearly spherical in form, and are composed of fine particles of —

dust or sand loosely bound together by means of silk (Pl. 32. fig.6). The cocoon resembles

its surroundings very closely, and even when found in captivity in vessels containing only —

a small quantity of sand and dust it is not easy to discover. On opening a cocoon its —

interior is seen to be white and smooth, being lined with silken threads closely woven

together. The average size of the cocoons taken from several specimens is 5 mm. long ~

and 3 mm. across.

The larva after spinning up remains in a resting condition for about fourteen days.

Tt is curved upon itself with the head bent towards the ventral side of the body, becomes

whitish in colour, and unless disturbed betrays no signs of movement. By about the

tenth day after spinning the cocoon, the trunk-region of the larva became darker in

colour and much swollen, the head and neck appeared as dead and empty husks, and,

moreover, the animal exhibited no movement. By the thirteenth day the larval cuticle

ruptured and the pupal appendages appeared externally.

The pupa measures 3 mm. in length, 1°8 mm. wide across the head, and 2°25 mm.

in maximum width. It is markedly flexed towards its ventral surface, and all

the imaginal appendages are clearly visible and enclosed in sheaths that are external in

position (fig. 7). The sheaths of the fore wings extend backwards to about two-thirds

the length of the abdomen. The extremely elongated hind wings are enclosed in sheaths

that are coiled on themselves after the manner of a watch-spring (figs. 7. & 8). They —

cross one another towards their bases, close to the hinder extremity of the abdomen, so —

that the right wing-case crosses the left one and comes to lie on the left side, while the f

left wing-case passes over to the right side (fig. 8). By this means they are conveniently

stored away in a compact manner so as to occupy a very small space. The head is

separated from the thorax by a narrow flexible neck derived from the first segment of

the neck in the larva. The labrum and frontal region of the head are but little produced

in the pupa, and totally different from the elongate shape they assume in the perfect

insect. The maxille and their palpi project freely forwards for a long distance in front

of the labrum. A pair of pupal or provisional mandibles is present, and when the

imago is about to emerge the pupa cuts a small roundish hole in the cocoon by means

of these jaws. When the imago emerges it leaves the pupal envelope still partly within

the cocoon. One imago was observed soon after it had emerged—the fore wings are

fully expanded before the hind wings. The latter at that stage were still partly coiled

upon themselves, and only gradually became straightened out. The larvee were reared

in a darkened and fairly cool room, and it was found that the time the insect spends

within the cocoon varies from 18 to 22 days. A larva that formed its cocoon on

March 15th emerged as a perfect insect on April 6th. Another that spun up on

March 20th emerged on April 7th.

Assuming that the imago is on the wing for 10 days before depositing her eggs, the

total life-history of the species from the egg to the winged state thus occupies a period

of eleven and a half months or a little more.

6. SUMMARY.

Croce filipennis is recorded in India from Bengal, Central India, and the United

Provinces. The imago is on the wing for about 14 days during the month of April.

It is principally crepuscular in habit, and frequents bungalows and other buildings.

Its complete life-history occupies a period of about 114 months.

The eggs are oval and greenish in colour and measure ‘5 X°3 mm.; they are laid singly

and are concealed with a coating of particles of sand and dust. Six captured females

laid from 13-40 eggs apiece, and a period of 10-12 days elapsed before they hatched.

The young larva measures 1:5 mm. long, and is of the same general type common

among the Hemerobiide and closely resembles that of the Ascelaphide. The body is

divisible into a head, a “neck ’’-region of two segments, and a trunk-region of appa-

rently ten segments. The second segment of the “neck” is the prothorax, and the

_ first two segments of the trunk-region represent the meso- and metathorax respectively.

During larval life it is exclusively carnivorous, and was reared upon Psocids and

7 young larvee of Dermestes. It feeds by means of suction, the maxillx fitting into a

groove beneath the mandibles, the two parts together forming a pair of imperfect

_ suctorial tubes. The larva lives among accumulated dust and sand on the floors of

| buildings. The full-grown larva averages 7 mm. in length, and differs from the young

larva in being pigmented, flatter in form, and in the proportionately larger size of the

trunk-region.

The pupa is enclosed in a nearly spherical cocoon composed of particles of sand and

_ dust woven together by threads of silk. The insect spends about three weeks within the

- cocoon, and the pupa is provided with a pair of provisional mandibles for cutting through

its wall to allow of the emergence of the perfect insect.

The author was able to observe the actual formation of the cocoon, and states that the ©

larva exudes the silk from the hinder extremity of the body. A retractile straight 7

needle-like process is thrown out and taken in alternately, which applies the silk to the

particles of sand. A brief description and figures of the larva are given, but no account

of the pupa. I am indebted to Mr. T. Bainbrigge Fletcher, of the Agricultural

Research Institute, Pusa, for bringing this note to my knowledge.

XI. Synagoga mira, a Crustacean of the Order Ascothoracica.

By Canon A. M. Norman, W.4., D.O.L., LL.D., F.RS., ELS.

(Plates 33-35.)

Read 20th June, 1912.

PROF. DE LACAZE-DUTHIERS published in 1882 a monograph of a small and

remarkable Crustacean which he found off the Algerian coast, parasitic upon a new

Antipatharian which he named Gerardia. This parasite he called Laura gerardia *.

This Crustacean was covered by the polypes of Gerardi, except avery small opening

on the dorsal margin. It was contained in a Cypris-like sheath formed by two very

large valves, which were five or six times the length of the body itself. Lacaze-

Duthiers bred the young and assigned the species to the Cirripedia, establishing for it a

new group which he styled “ Ascothoracide ou Rhizothoracide,” the former of which

names has since been generally adopted.

Since the publication of Lacaze-Duthiers’ admirable and exhaustive monograph five

more species of the group have been discovered :—

1. I briefly noticed a species, which is the subject of the present paper, in the

Report of the British Association 1887 (1888), p. 86.

2. Dr. G. H. Herbert Fowler+ described a curious Crustacean parasite which

he found in a specimen of the coral Bathyactis symmetrica which had

been dredged by the ‘Challenger’ in the Pacific Ocean in lat. 35° 41’ N.

long. 157° 42' E., in the great depth of 2300 fathoms.

3. Mr. N. Knipowitsch { found a species in the White Sea inhabiting the two

Echinodermata Echinaster sarsii and Solaster papposus; this species be named

Dendrogaster astericola.

4. M. Otto le Roi§ has described two additional species of Dendrogaster—the one

D. arborescens from Dipsacaster sladeni, Alcock, the Cape; and D. ludvigi from

Echinaster fallax, Mill. & Trosch., the Philippines.

Monsieur A. Gruvel, in his ‘Monograph des Cirrhipédes ou Thécostraces,’ 1905,

instituted a distinct order Ascothoracica to receive these forms and has made each of

_ them a type of a new family—Synagogide, Lauride, Petrarcide, Dendrogasteride.

CIRRIPEDIA.

Order ASCOTHORACICA.

SyNAGOGA MIRA, Norman.

In 1887, when working at Naples, Signor Lo Bianco brought me some parasites in

spirits which he had found on the Actinozoan Antipathes larix, Esper. The parasites

were external and had all been removed from the host to which they had been attached.

These most interesting parasites I briefly described in the British Association Report

for 1887 (1888), p. 86, under the name Synagoga mira. I purposed to write a full —

account of this species shortly afterwards, but I delayed doing this in the hope of being

able to procure the earlier stages of development, which I had requested Signor Lo

Bianco to kindly look out for me; these, however, he was unable to procure. About

two years ago, finding that my material was not sufficient to clear up certain points

connected with the sexual characters, I wrote to Dr. Giesbrecht to ask him if he could

procure for me some further, and fresh, specimens of the species. He has now written

me to say that, although he has examined such specimens of Antipathes and Isis as had

come into the Station, he has not been able to meet with Synagoga. He tells me that

the two genera just mentioned are much scarcer in the Bay than they used to be; he

adds that “ Synagoga has not been found in the Bay of Naples since the time that you

described it.’ It would seem, therefore, that the species must be extremely rare. As

long ago as 1890 I had a series of illustrative drawings made for me by Mr. A. Scott;

a few additional drawings have been made by Mr. KE. Popple.

The Synagoga is enclosed in a mantle or sheath in form as the bivalve of Cypris or

Estheria. This enclosing sheath is nearly ovate (Pl. 33. fig. 1), somewhat narrower in

front, where it is slightly emarginate above; its measurements when full-grown are 4 mm. —

in length and 3 mm. in breadth; the external surface is covered with minute triangular

spinules which are somewhat larger towards the margins; the eggs are contained ia

ovaries within the sheath. The animal itself is attached by two very strong bundles of

muscles to the upper portion of the sheath, and with this exception enjoys perfect

freedom of motion ; it is rarely withdrawn wholly within the sheath.

The body consists of a cephalon, furnished with very large and strongly developed

antennules (Pl. 33. fig. 2), very prominent buccal mass, and the peculiar organ hereafter

to be described. The mesosome or body is composed of six segments bearing six pairs of

legs. The metasome or tail is five-jointed, of which the first is the genital segment; this

is followed by three segments without appendages, and the fifth which carries distally

a pair of serrated spines and two large unjointed rami, which remind one of the same_

organs in Nebalia bipes.

The antennules (Pl. 33. figs, 2 & 3) take the form of grasping-organs of remarkable —

size and strength, strong muscles also uniting the several joints. The first joint is about

OF THE ORDER ASCOTHORACICA, 163

equal to the second, or rather longer, and smooth; the second joint is bent at an angle

with the first, and has at the base behind a bunch of small cilia, the front is smooth. The

third joint is triangular, wider mm front than behind, with a bunch of delicate cilia on the

proximal half of the front margin. The fourth joint is narrowly triangular, the greatest

width is behind; in front it is projected into a small lobe which is furnished with two

strong produced spines, the front margins of which are serrated; beyond these large

spines are two or three small denticulate processes: this peculiar formation of the

fourth joint seems to suit it for uniting with the terminal claw to form a strong

grasping-organ. The fifth joint is longer than the combined length of the front margins

of the two preceding joints; it tapers gently from the base to the extremity and is

fringed throughout the front margin with very large and finely plumose sets. The

sixth joint is subequal in length to the preceding: from near the base of the hind

margin there is projected a lobe which is more than equal in length to the breadth of

the joint ; at its base this lobe gives out a little process which carries a long and peculiar

seta and terminates in three long sete. Moreover, near the distal extremity of the

same margin of the joint another articulated lobe is seen, which terminates in three

setze. Beyond this on the side of the joint spring three small sete. The limb ends in

a strongly curved claw denticulated on its inner edge and furnished with a small seta on

its side.

The mouth-organs are enclosed in a very large pear-shaped sheath much constricted

at the base (Pl. 33. fig. 2 and Pl. 34. figs. 1 & 2), and thence swelling out and then

“narrowing to the extremity ; this sheath bears a bundle of down-like cilia at half its

length, and the extremity is drawn out to a spine-like point bordered with a few minute

cilia (Pl. 34. fig. 2). Within this sheath are a remarkable series of organs, the structure

and arrangement of which will be better understood from study of the illustrations

given than from any verbal description ; one of the outer pair of mouth-organs is repre-

| sented in fig. 3. The next pair are shorter and may be seen in fig. 4. The beautiful

and complicated structure of the third pair is seen in fig. 5, while the split teeth of its

oe are shown in the more enlarged drawing fig. 6. The central organ with its

powerful and acute termination and saw-like edge behind is represented in fig. 7. It

would appear that there is only one of this central organ, while the other organs are in

pairs.

The six pairs of feet are all composed of a two-jointed peduncle and two branches.

The outer branch in all cases is composed of two joints; the inner branch of the first

and of the sixth pairs is two-jointed, while that branch in the second, third, fourth,

and fifth pairs is three-jointed. The first pair (Pl. 35. fig. 1) has the basal joint of the

peduncle without setze, the second joint carries three sete on the distal portion of the

inner face. The inner branch consists of two joints of subequal length, of which

the first carries about five seta on the inner side and the second joint has three terminal

- sete ; the outer branch has the first joint as long as the whole of the inner branch and

“is devoid of sete, the second joint is equal in length to two-thirds of the first and

terminates in a dense bunch of setxe. The second feet (Pl. 35. fig. 2) have the peduncle

164 CANON A. M. NORMAN ON A CRUSTACEAN

of very much stouter proportions than those of the first feet; the first joint carries one

distal external seta and the inner margins of both joints are densely setose, the inner

branch has three joints nearly subequal to each other in length and are densely setose

on the inner margins and the apex, the outer two-jointed branch has the first joint equal —

in length to the first two joints of the inner branch; the second joint is fully twice as

long as the terminal joint of the inner and is setose both on the inner and outer —

margins; the third, fourth, and fifth feet are of very similar structure to the second —

just described. The sixth pair (Pl. 35. fig. 3) has the first joint of the peduncle long ~

and comparatively narrow ; there are no conspicuous sete either on that or the following ~

joint. Both rami are two-jointed and furnished with long sete, especially on their

inner margins.

The Jast joint of the metasome (PI. 35. fig. 7) carries two spines, which are considerably

longer than the breadth of the segment from which they spring ; these spines have the

margins serrated. Besides these spines the body terminates in two one-jointed uropods

(Pl. 88. fig. 6); these uropoils are more than twice as long as the preceding segment, on

the outer margins they carry two plumose sete and two terminal, while their inner

margins are densely clothed with similar sete; the outer margins of these rami are —

dentate from the base to the origin of the first external seta. With respect to the

organs of generation, I am not able to describe them satisfactorily, and it was chiefly

with a view of examining them more fully that I desired to procure fresh specimens of

Synagoga. Posteriorly to the sixth pair of feet on the first segment of the metasome a

peculiar organ is found which appears to be that of the male. At half its distance

from the base a portion bends downwards and terminates in a conical point which

appears to be the penis; beyond this point the limb arches and is gradually attenuated.

Pl. 35. fig. 4 represents this appendage as seen from side. Fig. 5 (which is, however,

partly diagrammatic) gives the appearance as seen from below. We find other specimens

in which the first segment of the metasome is more produced downwards than the last

segment of the mesosome (PI. 35. fig. 6), and this produced segment is crenulated at the

extremity and on the front margin; this would appear to represent the vulva of the

female, and thus it would seem that the two sexes are separate.

Behind the antenne there is an organ which occupies the place of what Lacaze-Duthiers

calls in Zawra the first feet: the organ here can scarcely be regarded as a foot, inasmuch

as behind it we have six pairs of distinct feet, nor does it present the appearance of a

foot ; nevertheless it would seem to discharge part of the functions of the first foot i

Lawra, inasmuch as I take the papilla to be the orifice of the oviduet which brings the

ova from the ovary, situated beneath the mantle. Of this organ there are given thre

illustrations (Pl. 34. figs. 8, 9, 10), but for the differences between them I am unable

to account. ;

Pl. 83. fig. 5 represents a tubule containing ova from beneath the mantle. Fig.

represents a portion of the margin of the mantle and shows the more fully develope

ova within.

The several genera of the order Ascothoracica differ in development of the variou

organs, and these changes have, doubtless, been brought about by the more or less

OF THE ORDER ASCOTHORACICA. 165

distinctly parasitic mode of life of each species. The Petrarca bathyactidis of Fowler

inhabits the Actinozoan Bathyactis symmetrica, and lives in the mesenterial chambers

of its host. Active powers of locomotion would be useless, and the limbs and tail are

merely represented by lobes of the body. The antennz are an exception, ending in

two nails and a spine. Yet we find strong resemblances in the enclosing mantle, form

of the buccal cone, and general structure to the other genera.

In the Dendrogaster astericola of Knipowitsch we again have an internal parasite

within the body of the Echinoderms ehinaster sarsii and Solaster papposus. What

the author draws as figure of the “Zarve au stade Cypris” so closely accords in

general structure with Zawra and Synagoga that it seems impossible to regard it as

an immature form.

Laura gerardie of Lacaze-Duthiers, the most fully described species, has its body

covered over by the Gerardia, so that it is protected in a great measure from outside

interference, and it is contained in such a gigantic test that were it free it seems

impossible that it could lift so large a mass; moreover, its limbs are free from

swimming-setze.

Synagoga mira is less protected than the preceding genera; it lives externally upon

the Antipathes, and instead of being covered by the host it simply clings to it by

its massive antennz and would seem to have the power of relaxing its hold and

swimming off to attach itself to another part of the host. Its bifid feet are largely

furnished with setze, which would enable it to swim easily.

As compared with Laura, Synagoga shows the following points of difference :—In

Laura the mantle which enwraps the body is of a prodigious size, in Synagoga it is

only large enough just to cover the body. In Zauwra the antenne are small and

insignificant ; in Synagoga they are very large and strong, and the mouth-organs are

much more highly and elaborately developed. In Laura Duthiers finds a very small

organ which he styles “‘antennules ou tubercules sous-céphaliques ” ; of these I have not

been able to find any trace in Synagoga. Laura has only six pairs of unbranched feet,

of which the first pair contains the female organ in its upper portion and also discharges

the matured ova; the four following feet have at their bases the organs of the male,

and thus the animal is an hermaphrodite. The feet, being without setose adornment,

are unfitted for swimming. Synagoga bears the peculiar organ (Pl. 34, figs. 8-10)

which would seem to discharge at least some of the functions of the first feet of

Laura; behind this are six pairs of bifid feet, which are densely setose, and behind these

there are appendages of the first segment of the metasome, which, differing in character

in different specimens, are regarded as the distinctive organs of two separate sexes.

Lastly, Synagoga has the terminal rami much more fully developed, and, moreover,

carries two large spines on the last segment of the metasome above the well-

developed rami.

1. IntTROoDUCTORY REMARKS.

‘THE Embiide form a small and well-defined group of Insects of very wide dis-

tribution. In their range they are almost cosmopolitan, being absent only from the

polar and cooler temperate regions of the earth. They exhibit a remarkable simplicity

and uniformity of structure which are partly due to primitive features in their

organization, and to the fact that certain other characters have been probably

secondarily acquired through degeneration. They further exhibit in almost all of the

species very marked sexual dimorphism. It has long been known that the individuals

of both sexes have the faculty of secreting silk, with which they manufacture the

tunnels constituting their nests. That the Embiide are an ancient group, and now

long past the zenith of their prime is probable. In this respect they are worthy of

comparison with Peripatus and Anaspides among other Arthropods.

The described species of Embiide are about sixty in number, the exact figure

depending upon the validity of certain specific names. So far as I have been able to

ascertain, forty-two of these species have been based upon an acquaintance with one sex

SECOND SERIES.—ZOOLOGY, VOL. XI. 27

168 DR. A. D. IMMS ON

only, thirty-nine being founded on male examples and three on female. From this it is

evident that in only 18 species, or 30 per cent. of the total number of known species,

have both sexes been described. Among the Embiide in particular, unless both sexes

happen to be taken in association with one another, it becomes a matter of great

difficulty afterwards to correlate a particular male with any particular female. Owing

to this cause, and also to the fact that both immature and mature winged examples are

frequently taken, a good deal of uncertainty exists at present with regard to several

species. The unsuspected discovery that, in at least four species, the males are

dimorphic, further’ complicates matters. As additional species become known, these

difficulties are liable to result in the synonymy of the Embiidee becoming complexly

involved. It is therefore imperative, in my opinion, that entomologists should refrain

as far as possible from describing new species of Embiidze based upon one sex only.

In the case of the males, the best and most constant characters are those afforded

by the structure of the two terminal segments of the abdomen. The gratitude of all

students of the Embiidz is due to Enderlein, who is the first investigator to attempt

systematically to study this region of the body. His recent monograph (1912) for this —

reason makes a most important advance in our knowledge of the group.

Hitherto only four species of Embiidze have been recorded from India, and all

pertaining to the genus Oligotoma, Westw., viz. :—

Whether these four names represent four separate and distinct species is extremely

doubtful. Enderlein (1912) regards O. bramina as being a synonym of O. michaeli, —

while Krauss (1911) in his ‘‘ Monographie der Embien” considers them to be two

species. On the other hand, Krauss regards O. latreillii as beg a synonym of

O. saundersi.

Embia major is remarkable in being by far the largest species of Embiide yet

discovered.

The genus Hmbia, Latr., furthermore, has not previously been known to occur in any

part of the Oriental zoo-geographical region. In the bordering countries of the

Palearctic region three species of the genus, however, are known to occur, viz. :—

EMBIA MAJOR FROM THE HIMALAYAS. 169

In July 1909 I had the good fortune to meet with two large male Embiids belonging

to the species herein described for the first time. They occurred among herbage

growing along the sides of a rivulet, at an altitude of 4600 feet, in the Naini Tal

district, in the Himalayan foot-hills of Kumaon. Since that time, I have visited various

parts of the same district at different times of the year, and have been successful in also

procuring the female, the eggs, and the silken nests of the insect in comparative

abundance. I was thus enabled to make a more extended series of observations on the

habits and post-embryonic development of a single species of Embiidz, than has fallen

to the fortune of previous students of the group.

2. DESCRIPTION OF THE MALE.

Deep brown-black, clothed with dark brown or almost black hairs. The antennze

20—29-jointed, a little shorter than the combined length of the head and thorax. The

head, thorax, and abdomen mutually related in length in the proportion of 3:5: 8.

The first joint of the hind tarsi with two arolia. The 10th tergum completely divided

into a pair of plates, the right being considerably larger than the left. The left plate

produced into a stout curved process ; the process of the right plate only represented by

a minute papilla. The process of the 9th sternum large, curved at the apex only.

Basal joint of the left cereus much enlarged, conical; its proximal surface armed with

numerous minute scattered denticles. Distal joint of both cerci similar to one another.

Upper wing 8°5-11:25 mm. long, 2°75-3°5 mm. broad ; lower wing 8-10°5 mm. long,

2°5-3'5 mm. broad.

Length 12°75-18 mm.

Tue Heapv.—tThe head is longer than broad with the posterior margin rounded ; it

attains its greatest diameter between the eyes. It is uniformly clothed with longish,

almost black hairs. The eyes are only partially visible from above, reniform in shape,

and have their concave side closely embracing the basal joint of the antenna.

The labrum is much broader than long, with its anterior angles prominently rounded

(Pl. 38. fig. 8). It presents no special features. The epipharynez is represented by a

longitudinal row of setze on either side of the pharyngeal surface of the labrum. These

setze are most probably sensory in function. The clypeus is larger than the labrum and

is divided into a membranous ante-clypeus (a.cl. in fig. 8), and a wider and fully chitinised

post-clypeus (p.cl.), which articulates with the epicranium just in front of the bases of

the antenne.

The antenne vary in length from 6-7:°5 mm. and are larger than the thorax, but a

little shorter than the combined length of the head and thorax. The number of joints

varies between 20 and 29, the most usual number being from 23-27. More than half

the individuals examined had one or both of their antenne imperfect. The basal joint

(Pl. 38. fig. 2) is the widest, and the third joint the largest ; the succeeding joints differ

very little individually among themselves. The combined length of the 4th, 5th, and

6th joints exceeds that of the first two joints.

The mandibles (Pl. 38. fig. 5) are slender, considerably longer than broad, and much

20*

170 DR. A. D. IMMS ON

less massive than those of the female. They are armed with two very small apical teeth

placed side by side, and there are no other definite teeth. Below the apex of each

mandible the inner margin is produced for less than half its length into a sharp cutting-

edge. The inner angle of each mandible is somewhat produced, and to it is attached

the tendon of the adductor muscle (add.).

The ginglymus (ging.) is directed obliquely outwards and lies above and partly behind

the condyle (cond.). To the outer angle of each mandible is attached the tendon of the

abductor muscle (abd.), but there is no special process developed.

The first maxille each consist of a five-jointed palp, a membranous galea, and a stout

lacinia, carried by the cardo and stipes (Pl. 38. fig. 11). The joints of the palpi are

related to one another in length in the proportion of 17:9:15:18:22,—the second

joint being much the shortest and the apical joint the longest. The galea (gal.) is

membranous and unarmed. The lacinia (lac.) is strongly chitinised and armed with a

pair of small apical teeth situated side by side; along the inner margin of the lacinia is

a row of stiff elongate setee. The cardo (car.) and stipes (st.) present no special features ;

the former is the larger of the two joints.

The second maxille (labiwm) consist of a quadrangular submentium (m, in Pl. 38. fig. 9),

a well-developed mentum (m,). They differ considerably in form from those figured by

Grassi and Sandias (1897, pl. 19. fig. 7) for Haploembia soliert (Rambur).

Arising from near the base of the submentum are the labial palpi (l.p.), which are

three-jointed. The joints are related to one another in length in the proportion of

approximately 12:14:17. In some specimens, however, the two basal joints are

practically equal in size. A vestigeal palpiger is present, and its limits are indicated by

an indistinct suture (pgr.). Distally, the mentum carries a pair of large external lobes

or paraglosse (g.), which are the counter-parts of the galez of the 1st maxille. Situated

on either side of the median line, and between the paraglossze, are a pair of small pointed

lobes representing a divided ligula (/.) and corresponding to the lacinie of the

Ist maxillee. The mentwm exhibits indications of a paired formation being divided into

halves by an indistinct median line which is much less chitinised than the rest of the

sclerite. The hypopharynx appears as a median projection from the floor of the mouth.

Viewed from above it appears quadrangular in form, and longer than broad. Its dorsal

surface is invested with a covering of extremely minute scales, which are pectinate along

the distal margin. In many instances the middle tooth of each scale is prolonged into a

slender spine. On the ventral surface of the hypopharynx the scales become less

-numerous and disappear. Such scales have also been noted and figured by Enderlein

(1909, p. 168, fig. 3) in Oligotoma saundersi, Westw., who regards them as taste-scales.

Tue THorax.—The prothorax is narrower than the head, sub-quadrate, but slightly

broader than long. Its anterior margin is straight and the sides slightly diverge

posteriorly, The hind margin is produced into a median convexity (Pl. 37. fig. 1).

The anterior fourth of the tergum is definitely constricted off from the rest by means of

a deep transverse sulcus. At right angles to the latter and terminating in it anteriorly,

is a shallow median longitudinal groove. Both the anterior margin and the sides are

ee ey LS ee ee ee

EMBIA MAJOR FROM THE HIMALAYAS. 171

clothed with stiff black hairs. The mesothoraz is the largest division of the three, sub-

quadrate in shape, slightly broader than long, and wider than the prothorax. Its anterior

margin is clothed with pilose hairs. The metathorax is entirely glabrous and a little

shorter than the mesothorax. The fore-wings vary in length from 8'5-11-25 mm., and

their breadth varies from 2°75-38°5 mm. The hind-wings vary from 8-10°5 mm. in

length and 2°5-3°5 mm. in breadth. The length of the wings compared with that of

the abdomen exhibits a certain amount of variation in different individuals. In some

examples the apices of the closed wings extend a little beyond the tips of the cerci,

while in other specimens they only reach far enough posteriorly to cover a portion of

the basal joint alone of each cereus. The newration exhibits a very wide range of

individual variation, especially as regards the transverse veins, and, furthermore, the

veins of the right and left wings frequently differ from one another. If examined

immediately after the last ecdysis, the wings are seen to be hyaline and the veins are

more clearly exhibited. When the full darkening of the chitin is attained the veins

are reduced to the condition of being merely darker lines of thickened cuticle following

the original neuration. A comparison of the wings in the hyaline and fully developed

conditions, shows that the neuration undergoes practically no reduction or modification

during the period taken by the wing-membranes to harden and mature. In some

specimens, however, certain of the longitudinal veins exhibit a tendency to dwindle away

at their apices, before quite reaching the margin of the wing. In this respect Hmbiu major

is an example of the first step in the reduction of the wing neuration, which attains its

maximum in the genus Oligotoma. 'The surface of the wings is clothed with minute pilose

hairs together with longitudinal rows of longer hairs. These latter are disposed along

the courses of the veins and in the areas between the veins (text-fig. 1), but are entirely

wanting from the hyaline longitudinal areas of the wing-membrane. The margins of the

wings are fringed with regularly arranged longish setz. In the text-figure the neuration

_ of an average specimen is represented. The terminology followed is that advocated

by Comstock and Needham (1898, p. 423), which is based on a study of the phylogenetic

: development of the wing-veins of Insects. The costal vein (c.) is confluent with the

anterior margin in both pairs of wings. The subcostal vein (sc.) is short, being less than

- one-third of the length of the wing; it tapers to a point and dwindles away altogether.

This vein is thickly chitinised, and just visible to the unaided eye. The radial vein (r.)

is the most conspicuous vein of all, being very strongly chitinised and much thickened

in calibre. Running parallel to, and almost in contact with the anterior and posterior

margins of the radial vein, are a pair of very fine dull red lines (a/. and pl. in text-fig. 1).

_ These two lines terminate a short distance before reaching the junction of the radial and

a a a ee

es .

median veins. They are termed by Enderlein (1912, p. 10) the “ Radiussaumlinien’

(Radiolimbolarien), and by Krauss (1911, p. 7) the “Radius- Nebenlinien.” They possess

a certain amount of value as a specific character, and may be conveniently referred to

as the anterior and posterior radial lines. A short distance before reaching the apex of

the wing the radial vein joins the median. A variable series of 4-7 transverse veins,

situated in the distal half of each wing, unite the costal with the radial vein. The median

vein and its branches are distributed over about one-half the total area of each wing

(m, m,—m, in text-figs. 1 and 2). It consists of two main stems (m and m,) arising close

together at the base of the wing. The upper stem bifurcates into two branches before

reaching the middle of the wing. The upper branch (m,) remains undivided and receives

the apex of the radial vein. It is, furthermore, united to that vein by a series of 4-6

cross-veins. The lower branch divides into two veins (m, and ms): the upper vein m, is

connected with m, by a variable series of cross-veins; the lower vein m, is united to m,

by one or two cross-veins. The lower stem of the radial vein (m,), as a rule, remains

undivided; in the left upper wing of one specimen, however, it was found to be

bifurcated (vide text-fig. 2). It is joined to the veins in front by 3 or 4 transverse

veins, and to the cubital vein behind by 1-4 similar veins. The cubital vein (cu.)

bifurcates at a distance from its origin equal to about one-third of its length. The

upper branch is joined to the median vein by the cross-veins just referred to; the lower

branch does not receive any cross-veins, but is greatly thickened and chitinised like the

radius, and clearly visible to the unaided eye. The anal vein (a.) is the smallest vein of

all and is unbranched; it is connected with the basal stem of the cubital vein by

a single transverse vein. Enderlein, however, remarks:—‘‘ Die Analis is die zarte

und hyaline Clavusnaht, die Axillaris lauft in der Mitte des Clavus kraftig und endet

ohne Nodulus-bildung vom Ende des Clavus in den Hinterrand” (1912, p. 10). This

interpretation I believe to be incorrect, for ‘‘ Nahte”’ occur between other veins also, and

can be seen in the newly formed wing immediately after the last ecdysis, before full

chitinisation has taken place. The vein which appears to me to represent the true anal

vein is the one heterms theaxillary. In text-fig. 2 are represented the greatest number

of veins that could ex hypothest occur in any individual pair of wings. It has been

constructed by combining in one figure the various variations that I have observed

in both pairs of wings of eight individual males. The neuration of the upper wing

shown in the figure agrees almost entirely with Krauss’s figure (1911, p. 7) of the

primitive hypothetical state of wing-neuration in Embiide, the only difference being

the much greater number of transverse veins in Hmbia major. In the bifurcation of

the lower stem (m,) of the radial vein, as an occasional and apparently rare variation,

_ we have a relic of an earlier condition. So far as I am aware, this only occurs as

a constant character in the genus Donaconethis, Enderl., where it is present in both

wings. Krauss (1911, Taf. 5. fig. 21d) figures the right wings of a specimen of

EE. savignyi, Westw., in which the vein m, is similarly hifurcated, though it is not usually

so in that species. In the lower wing of one specimen of /. major the radial vein passes

directly to the margin of the wing, instead of uniting with thé upper stem (m,) of the

median vein. This appears to be a reversion to a primitive condition which is found in

the generalised genus Clothoda, Enderl., and one or two other forms.

The legs do not present any special features, with the exception of the arolia* or

ventral pads of the tarsi. In relation with the hind pair of legs there are two such pads

on the first tarsal joint (metatarsus), and in this respect £. major differs from its

congeners and resembles the genus Haploembia, Verh. On the second tarsal joint there

* « Sohlenbliischen ” of Verhoeff.

174 DR. A. D. IMMS ON

is a single pad, as is usual among Embiide (text-fig. 3). The arolia on both joints of

the tarsi are completely glabrous. The tarsal claws (PI. 88. fig. 13) of each pair of legs

do not differ from one another in any essential points. Each claw is broad at the base,

but narrows and becomes acuminate at its distal half. It carries a stiff obliquely-

directed seta, which arises from the basal portion of the claw.

The ABDOMEN consists of ten terga, of which the first eight are almost glabrous. The —

pleura and the 9th and 10th terga are provided with brownish hairs. The first seven terga —

are subequal, the eighth is shorter than those of any of the preceding segments, and the —

ninth is asymmetrical and the smallest of all: it appears as if compressed between the

8th and 10th segments, and partly distorted in consequence, so that the right portion

appears somewhat larger than the left (Pl. 37. fig. 3, ¢g.,). The tenth tergum is —

completely divided into right and left plates, the right being larger than the left. The

_ left plate is produced posteriorly into a stout curved process (pr.ég.10 in text-fig. 4); _

the process of the right plate is only represented by a minute papilla (7.p.). The left-—

hand portion of the right plate (m.p. in text-fig. 4) is marked off by means of a suture

from the rest of the plate. Ventrally, the abdomen consists of nine evident sterna. The

first sternum is extremely small and firmly soldered to the posterior margin of the meta-

thorax. The 2nd-8th sterna differ but little among themselves, the 2nd, 3rd, and 4th

being somewhat longer than the succeeding sterna. The ninth sternum is the largest of

all; it is asymmetrical, and forms the subgenital plate; it appears to be formed by the

fusion together of the ninth sternum and the right plate of the tenth sternum. Whether

EMBIA MAJOR FROM THE HIMALAYAS. 175

the left-hand portion of the tenth sternum of the nymph participates also in its formation.

is extremely doubtful. From a prolonged study of the insect, in different stages of

development, I have come to the conclusion that the left plate of the 10th sternum

becomes modified, but persists as ventral process (v.p. in Pl. 87. fig. 8 and in text-fig. 4).

.This process is hinged to the subgenital plate, and is attached to it in the large posterior

- concavity, which is shown in Pl. 87. fig. 2. Krauss, however, regards this structure as

the “Grundplatte” (basal plate) of the left cercus (1911, p. 12). Enderlein (1912)

_ describes it as the “ Anhang” of the ninth sternite, which is in accordance with the

4 morphological explanation suggested above.

The basal joint of the left cercus is sub-conical in shape (Pl. 37. figs. 2 & 8, and text-

fig. 4). Its greatest diameter is at the proximal end and measures double that of the

corresponding joint of the left cereus. The proximal surface is excavated to form a

prominent concavity (fig. 2), over which are distributed a number of small denticles

_ (text-fig. 4). The inner wall of the concavity is strongly rounded and is situated beneath

the ventral process already referred to. The distal joints of both cerci are elongate and

cylindrical, and similar one to the other.

CoLoration.—Seen from the dorsal side, the head, together with its appendages, the —

legs, the terminal and penultimate segments of the abdomen, and the cerci except at —

their apices, vary in coloration from deep brown-black to black, with pruinose reflections,

The prothorax varies from chestnut-brown to black, but in most specimens it is usually ~

brown-black in colour. The remaining thoracic and abdominal segments are dark

pruinose-brown. . The claws of the feet are yellowish-white, but fuscous distally. The -

articulations between the joints of the legs, of the tarsi except the first pair, of the

antenne, and of the labial and maxillary palpi are cream-coloured. The ante-clypeus is —

usually light brown and very conspicuous for that reason, and the apices of the cerci are —

yellowish-white or cream-coloured. The intersegmental regions between the head —

and the prothorax, and between the prothorax and the mesothorax are well defined, —

membranous, and yellowish-white in colour. The pleure of the metathorax and the —

fist eight abdominal segments are similarly membranous, and form a whitish sinuous —

line along each side of the body, but are less conspicuous than in the female.

Ventrally the coloration is very much the same as it is dorsally. The cervical region —

is a very conspicuous, yellowish-white, membranous area, and the region between the —

prothorax and mesothorax is similarly membranous.

The wings are fuscous, striped with a series of longitudinal hyaline areas (Pl. 37. fig. 1). —

These areas have a definite arrangement with reference to the various longitudinal veins, —

and are, furthermore, devoid of the longer setze which are distributed over the rest of the

wings. As already mentioned (p. 171) the newly formed wing, after the last ecdysis, is at —

first hyaline, the darkening and full chitinisation taking place subsequently, leaving only ~

these longitudinal areas unaltered. The latter remain unmodified and undarkened through- ;

out life. In this connection it is worthy of note that Wood-Mason (1883, p. 633) suggested —

that these areas represent the original hyaline colour of the wings; and it gives me great

pleasure in being able to confirm his suggestion. ‘The hyaline areas are disposed in the —

following manner:—(a) An extremely narrow strip bordering both the anterior and ~

posterior radial lines (p. 171); (2) a prominent area situated midway between the two —

branches m, and m, of the median vein; (¢c) a short area lying between the two veins m,_

and ms, formed by the division of the lower branch of the upper stem of the median vein ;—

(d) a very long and conspicuous area situated about midway between the two stems m —

and m, of the median vein and extending outwards so as to almost reach the outer margin ~

of the wing; (e) a very similar area situated between m, and the cubital vein; (/) one ~

or two very short lines lying within the fork formed by the bifurcation of the cubital —

vein; (g) a short area between the much thickened stem of the cubital vein and the —

anal vein. In those cases where the lower stem m, of the median vein is bifurcated, an —

additional hyaline area is present between the two branches of the fork. This, however, »

is a rare variation. At the points where certain of the transverse veins cross the hyaline _

areas (Pl. 37. fig. 1) they become bordered with a minute hyaline strip, producing the

appearance of cross-pieces on the wing-membrane.

EMBIA MAJOR EROM THE HIMALAYAS. 177

3. DESCRIPTION OF THE FEMALE.

Deep brown to brown-black, clothed with lighter brown hairs, longer and more

numerous than in the male. The antennz 23-29-jointed, shorter than the thorax.

The head, thorax, and abdomen mutually related in length in the proportion of

3:7:10. The first joint of the hind tarsi with two arolia. The 8th and 9th abdominal

terga subequal, but shorter than those of any of the preceding segments. The

10th tergum longer than the ninth, narrowing posteriorly with the hind margin

prominently rounded.

Length 14°75-20°75 mm.

The Heap differs from that of the male in that it attains its maximum width just

behind the eyes. The eyes, moreover, are smaller and less markedly reniform. The

antenne (PI. 38. fig. 3) measure from 5-6 mm. in length, and are shorter than the thorax.

The number of joints varies from 23-29 and, for the most part, they are shorter and

more annular than the corresponding joints in the male. The combined length of the

4th, 5th, and 6th joints is less than that of the first two joints. The dabrum only differs

from that of the male in that the hairs of the epipharynx are more numerous and rather

more elongate; they are similarly disposed in two longitudinal rows as in the male.

The mandibles (Pl. 38. fig. 6) are much more massive than in the male, and their biting-

edges are armed with four prominent teeth (1—4 in fig. 6). Two of the teeth are situated

close together at the apex of the jaw. ‘These are followed by a large and usually bilobed

tooth, occupying the middle of the biting-edge of the jaw. Near the inner angle there

is a fourth and somewhat smaller tooth which in some individuals is greatly reduced or

absent entirely. Immediately below this tooth (no. 4) isa basal process (add.) which

provides attachment for the adductor muscle of the mandible. The ginglymus (ging.) is

very prominent and is produced outwards on a stout pedicel. To the outside of the

ginglymus is the condyle (cond.), and at the extreme outer angle of the mandible is

situated the point of attachment of the abductor muscle (abd.). The first maville only

differ from those of the male in that the two apical teeth are considerably longer and

more prominent. The dorsal tooth is rather longer and more slender than the ventral

one. The mazillary palpi are five-jointed, and exhibit no appreciable differences in the

two sexes. The hypopharynx, in the majority of specimens examined, was found to be

slightly larger than that of the male, but does not appear to exhibit any essential

differences.

The Tuorax is longer than in the male, and consists of three annular segments whose

terga are extremely simple in structure, differing but little from those of the abdomen

except in size. ‘he deep transverse suture of the prothorax is situated, in some

specimens, rather further forward than in the male. The median longitudinal groove is

frequently produced beyond the transverse groove to the anterior margin of the pro-

thorax. The legs do not differ from those of the male in any essential features. The

tarsal claws are similar in both sexes and, in relation with the hind pair of legs, there

28*

178 DR. A. D. IMMS ON

are two ventral pads or arolia present on the first tarsal joint (‘‘metatarsus”) and a

single such pad on the second tarsal joint (text-fig. 3).

The ABDOMEN has its dorsal surface more hairy than in the male, this feature being

apparently correlated with the absence of wings. ‘The tergal plates of the 8th and 9th

segments are subequal in size, shorter than those of any of the preceding segments, and

the 9th tergite, moreover, exhibits noasymmetry. The 10th tergum is somewhat longer

than the 9th; it narrows posteriorly and the hind margin is prominently rounded

(Pl. 38. fig. 1). The 8th sternum is the swbgenital plate. It has a median transverse

incision in its posterior margin, which marks the position of the genital aperture (g.ap.

in Pl. 38. fig. 4). Thesterna of the 1st and 8th segments are smaller than any of the

remaining sterna. The 9th sternum varies from 2-2} times the length of the 8th, and

its posterior margin has a small shallow median notch. The 10th sternum, unlike that

of the male, is divided longitudinally into two symmetrical plates (st... in fig. 4), The

right and left cerci are similar to one another, and at the base of each cercus there is an

annular vestige, which may possibly represent the basal plate *, present in relation with

each cercus in the primitive genus Clothoda, Enderl., and well developed in most

Embiid larvee.

CoLoraTrion.—Dorsally the coloration varies from uniform dark brown to almost

black, and in some lights it appears quite black. The intersegmental regions between

the head and the prothorax, between the prothorax and mesothorax, and between the

mesothorax and metathorax, are membranous, flexible, and whitish in colour. The

pleural region commences from the basal. half of the metathorax and extends backwards

to the extremity of the 8th abdominal segment, and is similarly membranous. It

appears as a prominent whitish line running along each side of the body, and visible

dorsally as a pair of lateral streaks (Pl. 38. fig. 1). The antenne are similar in colour

to the head, with the articulations between the individual joints paler. The distal half

of the clypeus (ante-clypeus), the labial and maxillary palpi, the region around the

articulations between each of the joints of the legs, the two apical joints of the anterior

tarsi, and the tibize and tarsi of the middle and posterior pairs of legs are lighter in

colour than the rest of the body. The claws of the feet are yellowish-white with

piceous apices, and the cerci are yellowish-white at their extremities. Ventrally the

coloration is paler than dorsally, with a slight primrose tinge in many individuals. The

sternum of the 8th, with the exception of its median portion, and the sterna of the

9th and 10th segments are darker in colour than those of the preceding abdominal

segments.

5. Systematic Postrion oF THE SPECIES.

Embia major is more closely allied to #. sabulosa, Enderlein (Denskr. med. Naturw.

Ges. Jena, Bd. 18, 1908, pp. 847-48, with 2 figs.), from South Africa, than to any other

species of its genus. The male of major agrees with that of sadulosa in the form of the

basal joint of the left cercus, in the absence of any evident process to the right plate of

the 10th tergite, and in the completeness of the neuration of the wings, all the longi-

tudinal veins attaining the wing-margin. The following characters, among others,

readily separate the two species :—

E. major, Imms.

Male measures 12°75-18 mm. in length.

Female measures 14°75-20°75 mm. in length.

Number of antennal joints varies from 20-29.

10th abdominal tergite of the male completely

divided into right and left plates. The process

of the left plate short and very much curved.

E. sabulosa, Enderlein.

Male measures 7°5—-8'5 mm. in length.

Female measures 10-11] mm. in length.

Number of antennal joints varies from 17-21.

In the male the line of division between the right

and left plates of the 10th abdominal tergite

does not quite extend back to the anterior

}

margin of that segment. The process of the

left plate long, and only slightly curved at its

apex,

6. Tur Ova.

The eggs are oval in form, with a smooth and faintly glistening appearance, and are

pale cream-white in colour. In average size they measure approximately 1 mm. in

length and ‘5 mm. in diameter. Below are recorded the actual measurements made on

21 eggs deposited by five different females :—

It will be noted that the eggs vary from 1:02 mm.—1:22 mm. in length and from

52 mm.—65 mm. in diameter.

At one extremity of the egg is a large prominent operculum (PI. 38. fig. 12). This

operculum is broadly pyriform in shape, and where it comes in contact with the rest of

the chorion there is a well-defined rim or margin. The general surface of the chorion

is finely sculptured into a series of irregular hexagons. The diameter of these figures,

measured between two opposite faces, varies between ‘031-05 mm. (fig. 10). Over the

surface of the operculum the sculpturing is of a somewhat different character; it takes

EMBIA MAJOR FROM THE HIMALAYAS, 181

the form of a series of irregular polygonal areas bounded by very thick walls (fig. 9).

The inside diameter of these areas, the measurements being taken between opposite faces,

varies from °012-:018 mm.

The number of eggs deposited by each female was found to vary from about 60 to 100.

The eggs laid by eleven females, each inhabiting a separate nest, were counted, and their

numbers were as follows :—59, 69, 70, 71, 73, 77, 79, 82, 97, 98, and 106 respectively.

Oviposition takes place within the tunnels of the nests. In those instances where a nest

is occupied by more than one female, the latter keep their eggs separate and apart from

those of their companions. Each female deposits her eggs all together in an irregular

heap loosely bound by fine silken threads. Additional threads also secure the eggs to

the wall of the tunnel. The incubation period was found to vary from three weeks to

one month, or a little longer, according to the prevailing climatic conditions.

Between June 20th and July 4th, I visited the locality where Hmbia major occurs,

but after a prolonged search was unable to discover any eggs. On the latter date I had

to leave the locality and travel to Dehra Dun. I brought along with me, in a small zine

breeding-cage, two females and two males. The insects were afterwards separated as

two pairs, comprising a male and a female each, and placed in separate vessels along

with some soil and clumps of grass. The vessels employed were a pair of crystallising

dishes used by chemists, each dish being covered by a circular metal plate and kept in a

moderately cool room out of the direct rays of the sun. These females commenced

depositing their ova on July 9th and 10th. The first insect hatched out on August Ist,

one hatched out on August 4th, three more on August 5th, and the remainder were all

hatched by August 7th, the incubation period in these instances varying between 23

and 30 days. During the process of development the eggs did not undergo any change

of colour. During the second week in August 1912, I again had occasion to visit the

Naini Tal district, and devoted one afternoon (August Sth) to an examination of some

thirty nests of this insect. In every nest females, along with their ova, were in evidence.

Except in three nests, where a few first-stage larvae were found, none of the eggs had

hatched out. Dehra Dun is situated at the foot of the Himalayas, at an altitude of

- 2200 feet and hasa correspondingly higher mean temperature. This higher temperature

accounts for the captive larvee emerging at an earlier date than in their usual habitat.

Four batches of ova were brought from Sat Tal, and from these eleven specimens of a

new species of parasite of the family Scelionide, belonging to the genus Lmbcdobia,

_ Ashm., were bred out in Dehra Dun. This parasite, when it is about to emerge, eats

its way out of the egg by gnawing a hole through the chorion, towards the end of the

_ egg opposite to that which bears the operculum (PI. 38. fig. 12).

During the incubation period the female Hmbia constantly guards her eggs, resting

with them lying beneath her body. A more detailed account of this instinct is given

on p. 189.

182 DR. A. D. IMMS ON

7. Tot Newry Hatcuep Larva.

The newly hatched larva is entirely white, with the exception of the eyes, which

appear as a pair of purple-brown dots, and the brown strongly chitinised edges of the

mandibles. On one occasion the larva was observed in the act of emerging from the

egg. It issues head foremost and forces open the operculum, which remains attached

along a small portion of its periphery to the remainder of the chorion (Pl. 88, fig. 12).

In total length the newly hatched larva varies between 1°6 and 1:8 mm., the measure-

ments being taken from the apex of the labrum to the extremity of the last abdominal

tergite. It is a relatively specialised example of the Campodeiform type of larva,

and exhibits no primitive features in its organisation which do not also occur in

the female imago. The head, thorax, and abdomen are related in length in the

proportion of 5:4:7 respectively. The most striking feature in the external mor-

phology of the young larva is the relatively great size of the head; it is ovoid, and

exceeds the thorax both in length and diameter (Pl. 37. fig. 7). The head, body, and

appendages are clothed with rather long thinly-distributed hairs. The antenne are

9-jointed, and as long as or a little longer than the abdomen. The thoracic segments

are extremely simple in character, and are much shorter in proportion to their breadth

than in the adult. There is no marked indication of the transverse suture of the pro-

thorax, which is a prominent feature in the adult insect. The legs are remarkably

large, and the hind pair when extended backwards reach to a little beyond the apex of

the abdomen. They differ very little in form from those of the adult, both the enlarged

first joint of the fore tarsi and the swollen hind femora being evident. The abdomen

consists of nine apparent segments, the ninth and tenth segments not being completely

differentiated from one another. The cerci are two-jointed; the basal joint is very

small and annular, and measures only one-eighth of the length of the second joint. The

larvee are all similar to each other, no external traces of sexual differentiation being

noticeable. When removed from the protection of the parent, the young larve were

observed to weave delicate tunnels within a few hours after emergénce from the egg,

8. THE SECOND-STAGE LARVA.

In larve measuring from 3-3°5 mm. in length, certain differences are noticeable, and

by which they are readily distinguished from the newly hatched larva. At this stage in

post-embryonic development the larva was from 21-23 days old. It is pale pinkish

_ brown in colour, with the head and the margins of the thoracic and abdominal segments

somewhat darker. The appendages and the whole of the ventral surface of the animal

are pale and very little pigmented. The head no longer dominates the rest of the body,

it being shorter than the thorax. The antenne are 12-jointed, shorter in length than

the abdomen, and only a very little longer than the thorax. The thorax has increased

very much in length, and the transverse suture of the prothorax is completely formed.

The head, thorax, and abdomen are mutually related in length in the proportion of

5:7:10. The legs have grown comparatively little, and the posterior pair when ex-

tended can no longer reach to the apex of the abdomen. There are ten evident abdominal

ee ee

segments, and the 10th sternum is longitudinally divided into two lobes. The mouth-

parts closely resemble those of the adult in their general structure. The mandibles are

stout and broad, but partake more of the characters of those of the female than

the male.

9. Tor HALF-GRowN LARVA.

During the beginning of December the larva has passed through the first half of its

life. Measurements of these half-grown larvee were made, and their length was found to

average 9mm. The antennz at this period have 21 joints, and are of equal length to

the thorax. In colour the larvie are chestnut-brown, with the appendages and ventral

surface pale. I was not able to detect any external sexual differences among larvee of

this age. Ten abdominal segments are present, and the last sternum is longitudinally

divided into a pair of symmetrical plates. These persist throughout life in the female

insect, but are no longer evident in the male at the close of the nymphal period. ‘The

= le

basal plates of the cerci are relatively large and well developed. They are covered by

the 10th tergal shield and are consequently not visible dorsally. They are in contact

with one another on the mid-ventral line, and appear to be serially homologous with the

paired plates of the 10th sternum already referred to. That they are to be regarded as

_ the representatives of an 11th somite was first suggested by Enderlein (1903, p. 430).

The mouth-parts do not differ in any details, except in size, from those of the younger

larva. During the cold weather months up to March, the half-grown larva undergoes

very little growth, and remains to a large extent dormant. Individuals extracted from

_ their tunnels were observed to be much longer, and more sluggish over the construction

of new tunnels than they are at other periods in their life-history.

; 10. Tor Mate Nympu.

_ The nymphal condition in the male is characterised by the presence of wing-rudiments,

_ otherwise it only differs from the larva in its greater size. Its period of duration is

about two months commencing during the first half of May, when the young insect is

from 9-94 months old. The youngest nymph observed measured 11°5 mm. in length,

with wing-rudiments 1:25 mm. long. At the close of the nymphal instar, examples

(15-17 mm. in length are frequent. A nymph 15 mm. long has wing-rudiments

measuring 2°25 mm. in length.

Viewed dorsally, the body and appendages are light chestnut-brown in colour, the

head and the extremity of the abdomen being slightly darker than the rest. Ventrally

‘the insect is of a much paler colour. The number of antennal joints varies from about

23-25, and correlated with the development of the wing-rudiments the tergal plates of

the meso- and metathorax have assumed their triangular form seen in the fully-fledged

adult. }

The asymmetrical condition of the cerci and apical abdominal segments in the male

is acquired very late in development, and for this reason is probably a phylogenetically

_ recent acquisition. In the early nymph no indications are apparent at all (Pl. 37.

figs. 5 & 6), but in a fully-grown nymph the 10th tergite of the adult is clearly visible

SECOND SERIES.—ZOOLOGY, VOL. XI. 29

184 DR. A. D. IMMS ON

beneath the cuticle. It has undergone division into two unequal plates, which are seen

in process of development (Pl. 3%, fig. 4). Unlike the adult male, the nymph possesses —

ten abdominal sterna. The Ist sternum is much reduced and soldered to the posterior —

margin of the metathorax. The remaining sterna differ but little from their condition ~

in the adult, excepting those of the two terminal segments (Pl. 37. fig. 6). The 9th j

sternum is still unmodified, and exhibits no traces of asymmetry. The 10th sternite —

resembles that of the adult female in being longitudinally divided into two similar g

shields (sf. 10 in fig. 6). The 9th and the right plate of the 10th sterna subsequently ~

become fused to form the large asymmetrical swbgenital plate. In relation ‘with the ~

base of each cereus are two basal plates (b.p. in Pl. 87. fig. 6).

The mandibles differ from those of the adult male in being relatively stouter and more ©

. a

massive, and resemble closely those of the female.

11. THe Femate Nympu.

A nymphal instar in the female can scarcely be said to exist. It is indistinguishable —

trom the larva except in point of size and in the development of the genital aperture. —

It, furthermore, only differs externally from the adult in being paler in colour (light ~

pruinose or chestnut-brown) and with the cuticle less chitinised. The largest female

nymph measured 19:25 mm. long, and had 23 joints to the antenne.

12. OBSERVATIONS ON THE BIOLOGY OF THE SPECIES.

The nests of Embia major were only met with in a restricted area between the village 5

or “basti” of Bhowali and the Sat Tal lakes, in the Naini Tal district of the Kumaon ~

Himalaya. Sat Tal is one of a series of five lakes or “tals”? found in this district 3

of Kumaon. According to Theobald they owe their origin to obstructions in the local ~

drainage caused by the débris of old moraines when the glaciers receded at the close of —

the glacial epoch*. The name Sat Tal means “seven lakes,” and in former times —

seven small lakes actually existed. At the present day, however, only two lakes of ~

appreciable size remain, and the larger of these, Sat Tal proper, is situated at an altitude —

of 4500 feet above sea-level. The nests of the Embia were found at elevations varying —

between about 4900 and 5100 feet, and 12 miles distant from the lake. They occurred ~

under loose flat pieces of stone which lie scattered in the form of débris over a hill-side My

and open valley (text-fig. 5). Such situations are neither very dry nor very moist. The —

area within which Lmbia was found is very thinly forested, and the trees consist for the

most part of “chir” pine (Pinus longifolia), Himalayan oak (Quercus incana), and —

Rhododendron arboreum. Flat stones were selected almost without exception as the sites —

for the nests. Between the lower surface of such stones and the ground, the Embiids _

weave the silken tunnels which form their nests. The shape of the nests depends upon ‘

the form, length, and number of these tunnels. In eight nests the ground beneath ‘

such stones was found to be occupied both by the Hmbia and an undetermined species

of Termite. The tunnels of the Termite were alongside and in close contact with those —

of the Emilia. It is noteworthy that the two species of insect appeared to be on

perfectly amicable terms with one another, resembling symbiosis. Furthermore, it may

be mentioned that Wasmann (1904, p. 17) records an Embiid, Oligotoma termitophila,

occurring in nests of Zermes natalensis in the Soudan.

The restricted distribution of the Embia is difficult to account for, especially as

apparently similar localities are plentiful in the surrounding country. Altogether 211

nests of the species were met with, and they occurred over an area about 14 miles

in length. An examination of 180 nests was made with the object of obtaining informa-

tion with regard to number of individuals inhabiting each nest, and the relative

proportions of the sexes. Contrary to what would be anticipated from previous observa-

‘tions on Embiide, the female was found to be of much more frequent occurrence than

the male. From an examination of 130 nests, made from June 27th until July 3rd, 88

of them (or 67°6 per cent.) were found to contain females only, 30 nests (or 23 per cent.)

contained both males and females, while 12 nests (or 9:2 per cent.) contained male indi-

viduals only. From these figures it will be noted that males were only found in

82 per cent. of the nests that were examined. Some 268 individuals were found

inhabiting these 130 nests (vide table on p. 188), and of these 109 (or 40 per cent.) were

males and 159 females. This relatively high percentage among the males is somewhat

29*

186 DR. A. D. IMMS ON

remarkable, and is mostly owing to the fact that three nests (nos. 68, 89, and 125)

contained no fewer than 39 male individuals among them; in no other instances were

more than five males found in a single nest. The females have a marked tendency to be

solitary, which is indicated by the fact that 73 nests, or 61 pee cent. of the total number

examined, contained single individuals only. In the cases of the males this tendency

does not appear to be evident. Out of 42 nests containing males, in only 9 (or

14 per cent.) were single specimens found.

The form assumed by the nests is very variable (Pl. 36). Asa general rule, at least

three secondary or side tunnels are constructed, and these communicate with the larger

main tunnels of the nest. Certain of the side tunnels serve as entrance or exit passages,

while others terminate blindly. In most nests there is usually a hole or aperture present,

leading from one of the tunnels into the ground. ‘This hole is the entrance to a subter-

ranean passage or chamber (w.c. in Pl. 86); in some instances this chamber was found

to be lined with silk, while in others no silk was present. When disturbed the occupants

of a nest frequently take refuge in these subterranean passages, but it is by no means

always the case. I believe that their primary function is that of a place of retreat

during the dry hot weather. The nests further vary very much in size, and this to a ~

large extent depends upon the number of occupants therein. In the case of nests

inhabited by a single individual, or in some cases two individuals, only one or two

elongate tunnels of loosely woven silk are constructed, and the contained Embiids show

clearly from within. In those instances where several Embiids exist in association with —

one another, they all participate in the formation of a common nest. The latter then

assumes the form of a somewhat complex meshwork of tunnels. In the most complex

nests a series of superposed tunnels is present, the lowest layer extending for a short

distance into the earth. Such nests are the result of the combined efforts of a large

number of occupants. Much more silk is expended on their construction, and the walls —

of the tunnels are denser and whiter in appearance. A typical large nest is shown in

text-fig. 6. The largest number of individuals found inhabiting any single nest was 21.

Nest no. 47 (Pl. 36. fig. 2) contained four females and one male, and measured 1 foot

4 inches in length. Nest no. 20 (fig. 3) contained a single female only, and was excep- —

tionally large for the work of one individual; it measured 114 inches in greatest length

and 53 inches in maximum width. Nest no. 26 (fig. 4) contained one male and one

female. Nest no. 39 (fig. 5) contained two females; and nest no. 85 (fig. 8) contained

one male, one female, and one immature male.

The first step in the construction of a nest consists in the spinning of a tolerably

straight silken tunnel about 3 or 4 inches in length (fig. 1), and many nests occupied

by single individuals remain in this simple condition. From a reference to the table

given on p. 188, it will be noted that nests nos. 68, 76, 89, and 125 contained 21, 10, 19,

and 12 occupants respectively. Such nests attain a relatively high degree of complexity

(vide text-fig. 6). The various individuals contribute towards the construction of these

large nests, and exhibit in this respect something more than a simple gregarious instinct.

I regard these nests as a manifestation of an incipient tendency to colony formation, —

which has undergone little or no evolutionary development. Captive Embiids, when

EEE eee

]

EMBIA MAJOR FROM THE HIMALAYAS. 187

placed in a glass phial together, do not weave separate and distinct tunnels, but

manufacture one common structure which shelters them all. This faculty of producing

silk is developed equally in both sexes. When a nest is disturbed the occupants run

rapidly along the tunnels either in a forward or backward direction with equal facility,

and frequently take refuge in the underground chamber already referred to. Sometimes

when much disturbed they desert their nests and take shelter under neighbouring stones

or in surrounding herbage. They are capable of running very rapidly along the ground,

ten individuals. The minute black particles overlying the tunnels are the excrementa or “ frass ”

ejected by the insects. (A little less than one-half natural size.) (Westwood Bequest.)

but in no instance did the males make any attempt to take refuge in flight. In habits

they are most probably exclusively nocturnal. Although the herbage was explored by

sweeping, no individuals were met with in the daytime outside the nests.

From frequent observations I believe that the primary function of the silken tunnels

of the Embiide is protective. Any predaceous insect which attacks the Hmbza while

within the walls of its tunnel becomes entangled in the silken threads of the latter,

allowing the Hmbia to make good its escape. Grassi and Sandias (1897, p. 64) consider

that these tunnels serve to protect the body from too excessive transpiration, and to

retain about the Hmbia an atmosphere not too dry. It is difficult, however, to imagine

what difference these delicate tunnels could make in this respect—for instance, during

the intensely hot weather that prevails from March to June in the Punjab and United

Provinces. At such times of the year the amount of humidity in the air is negligible ;

nevertheless Embiidz flourish in those regions. Melander (1902, p. 22) believes that

the tunnels probably serve merely as a retreat.

Individuals placed in captivity are at first agitated, but they very soon settle down

and become seemingly adapted to new surroundings. On June 5th three females were

taken from three separate nests and placed in a glass phial closed with a cork stopper.

When examined two hours after capture they had spun a straggling silken tunnel and

were reposing within it. On another occasion a captive male was observed to have

already commenced manufacturing its tunnel within half an hour of its being captured.

During the process of weaving these tunnels the fore-legs are in active motion, the insect

at the same time occasionally turning about on the long axis of its body. In order to

construct the roof of its tunnel it turns over on to its back, presenting its ventral surface

towards the observer. Newly hatched larvae, when removed from the proximity of the

parent female, were observed to weave tunnels with equal facility to older individuals,

Insects in the act of spinning were observed with the aid of a Zeiss binocular microscope,

which allows of their movements being tolerably readily followed. The silk is extruded

at the apices of long glandular hairs situated on the ventral surface of the enlarged first

tarsal joint of the anterior pair of legs. ‘These threads are extremely fine and can only

be observed when the Embiids are retained in a glass vessel lined on the bottom with

non-glazed black paper. ‘The fact that a number of such threads are produced simul-

taneously accounts for the rapidity with which these insects weave their tunnels.

I hope to publish in a later paper the results of a prolonged series of observations

dealing with the much debated problem of the mechanism of silk production in the

Embiidz. A full discussion of this subject will be found in the memoirs of Grassi and

Sandias (1898, Appendix II. p. 62), Rimsky-Korsakow (1910, p. 153), Krauss (1911,

p. 15), and Enderlein (1912, p. 12).

Maternal care on behalf of the ova and young larve is strongly exhibited by the

females, in very much the same manner as has been long known to occur among

the Dermaptera from the observations of Frisch, De Geer, Xambeu, Green, and others.

The female Lmbia major shows very marked solicitude for the welfare of her offspring

after her first few eggs have been deposited. She takes up her position in close

proximity to the ova and usually concealing them, so far as possible, by means of

her body. If alarmed and driven away, she returns sooner or later to take up the same

attitude. When the young larve are hatched they remain around the parent female,

who conceals them, so far as she is able, by means of her body, very much after the

same manner as a hen guarding her brood of chickens. A female and her brood were

kept in a small glass trough and observed daily living in intimate association. When

separated from the parent the larvee were observed the next day to have regained their

former position. As the larvee approach their second stage in growth (p. 182), they

exhibit a tendency to wander away from the female and construct small tunnels for

themselves. ‘They are markedly social, the whole of a brood living together within a

complex silken meshwork of tubes.

Eimbia major was found to be both easy to rear and observe in captivity. Females

were kept in crystallising dishes such as are used by chemists, and measuring 10 inches

190 DR. A. D. IMMS ON

in diameter. A layer of fine earth, after being carefully sifted and examined for other

insects, Arachnids, &c., was spread for a depth of half an inch on the bottom, and a lid of

metal was placed on the top to prevent the Embiids from making their escape. In this

simple contrivance the females laid their eggs and the young brood developed to maturity.

The only dangers to be guarded against are mould and too great an amount of dryness.

The moisture sufficient for their welfare was afforded by lightly distributing some fresh

grass (pulled up along with the roots) over the surface of the soil in the vessel. This

device, furthermore, prevented the development of mould. The grass was changed once

a week during the cold weather and hot weather seasons, and once a fortnight during the

monsoon season. The females were found to be vegetarian in diet and thrived on the grass

supplied, no animal matter of any kind being given to them. When enclosed in glass

tubes they eat their way very readily through the cork stoppers and escape. Whether

the male is carnivorous, as has been suggested by Friedrichs (1906) in the case of Euro-

pean species, Lam unable to say. The great differences in the structure of the mandibles

in the two sexes certainly supports Friedrich’s suggestion. Those of the male are slender

and devoid of any crushing-edge, and in this respect bear a considerable resemblance to

those of carnivorous insects. On the other hand, I have reared the insect from the

ege-stage up to the nymphs of both sexes entirely on vegetable food. It is a remarkable

fact, however, if the male imago alone is carnivorous. ‘This point is certainly in need of

further investigation, which I hope to pursue at a subsequent opportunity.

The females lived in captivity for 65 months after oviposition; the males, however,

only survived for a short time after the eggs had been laid.

The complete life-history of the insect may be summarised as follows :—

were found is the second week in July, and that they have been met with up to the

second week in August. Similarly, the earliest observed date of the emergence of the

larva is the first week in August, and so on.

Expressed in a few words, it may be said that during the monsoon season the eggs are

laid and early larval development takes place. It is, furthermore, a period of rapid

growth. During the cold weather months growth is comparatively slow, and the larva

for a portion of the time remains partially dormant. In the hot weather season growth

takes place more rapidly than at any other time. During this period the larval stage

is completed, the nymphal condition passed through, and the imaginal state attained—

all taking place within a period of approximately two months.

13. SumMARyY oF ConcuLusrons.

Eimbia major, sp. nov., is the largest species of Embiide hitherto discovered, and the

first member of its genus to be found within the limits of the Oriental zoo-geographical

region. It is more closely related to FZ. sabulosa, End., from South Africa than to any

other species.

It occurs plentifully under pieces of stone scattered over a hill-side and an open valley

in the Naini Tal district of the Kumaon Himalayas, such situations being neither very

dry nor very moist. It is very local and occurred between elevations of 4900 and

5100 feet.

Females are more prevalent than males. Some 1830 nests were examined and 67

per cent. contained females only, 23 per cent. contained individuals of both sexes, and

9 per cent. males only.

The nests are very variable in form and composed of a network of silken tunnels. The

silk is produced by glands situated in the enlarged tarsal joint of the anterior pair of

legs. The faculty of weaving nests is possessed equally by both sexes, and also by the

larvee and nymphs.

The size of the nests depends to a large extent upon the number of individuals

inhabiting them. The largest number of individuals found in a single nest was 21.

Where several individuals are associated together in a nest it is to be regarded as the

manifestation of an incipient tendency to colony formation, which has undergone little

or no evolutionary development.

Maternal care on behalf of the ova and young larve is strongly exhibited by the females,

_in very much the same manner as occurs among Dermaptera. The female lives for at

least 64 months after fertilisation ; the male, however, is much shorter lived.

The eggs measure 1 mm. long and ‘5 mm. broad; they are oval, cream-white, and

have a smooth, faintly glistening appearance. The number of eggs laid by a single female

varies between about 60 anda little more than 100. They are laid during July and

August in the monsoon season, and are placed in an irregular heap within one of the

silken tunnels of the nest.

SECOND SERIES.—ZOOLOGY, VOL. XI. 30

The incubation period of the eggs varies between about 23 and 30 days. They are

parasitised by a minute Hymenopteron of the genus Hmbidobia, Ashm., family Scelionide.

The newly hatched larva is 1‘}6 mm.—1‘8 mm. long, and entirely white, with the excep-

tion of the eyes and the strongly chitinised apices of the mandibles. It is a relatively

specialised example of the Campodeiform type of larva, and exhibits no primitive features

which do not also occur in the female imago. The chief characteristics are the relatively

ereat size of the head, nine evident abdominal segments, and 9-jointed antennze. The

enlarged 1st joint of the anterior tarsi is present as in the imago.

Larval growth consists chiefly in increase in size, increase in the length of the abdomen,

the adding of numerous joints to the antennz, and the darkening of the coloration.

‘The larval period lasts from the end of July or the beginning of August until the

following May.

The nymph stages last about two months during May, June, and July. The female

nymph does not differ from the adult except in colour and degree of chitinisation. The

male nymph is chiefly characterised by the presence of wing-pads.

The characteristic asymmetry of the terminal abdominal segments of the adult male is

acquired very late in development, not being evident until the end of the nymphal period.

For this reason it is probably a phylogenetically recent acquisition. In the larvee, the

female, and the nymphs of both sexes a well-defined 10th sternum, consisting of a pair

of symmetrical plates, is present. The subgenital plate of the adult male is probably

formed by the fusion of the right 10th sternal plate with the 9th sternum, the left 10th

sternal plate persisting as the ‘“‘ ventral process.”

A study of the wing-neuration shows a remarkable degree of variation, no two speci-

mens being identical. Many of the variations are reversions to a generalised state

exhibited in more primitive genera.

The larvee, nymphs of both sexes, and females are vegetable feeders, and the mandibles

of the larvee and nymphs closely resemble those of the females; they differ from those of

the male in being much stouter and provided with a crushing-edge. ‘The possibility

of the male alone being carnivorous requires further research.

INTRODUCTION.

THE cruise of Professor Herdman’s Steam Yacht ‘ Runa’ for the year 1913 provided

us with twenty-five bags of Foraminiferous material, both dredgings and shore-

sands, collected by Miss Catherine Herdman between the 10th of July and the

8rd of September. In addition, there were a few small samples of mud washed from

Invertebrata which had been preserved in alcohol.

The original intention of the Collectors was to supply us with a series of samples

linking up in some measure our Clare Island (W. of Ireland) material and the

dredgings of the International Fisheries Commission (Scotland) Cruiser ‘ Goldseeker,’

for the purposes of the ‘ Monograph of the British Recent Foraminifera’ upon which

we are engaged. The examination of the first four samples in Register (not Geo-

graphical) order, however, made it clear to us that we were confronted with an extremely

valuable series of gatherings, which would add many important records to the list of

hitherto-identified British species, and we consequently laid our other work aside and

devoted the period from October 1913 to November 1914 to the examination of the

material with a view to the production of this Monograph, regarding it as an important

contribution to our larger work.

The results have amply justified our anticipations, for, though we only record one

(? two) species and one (? two) varieties new to Science, no less than twenty-seven species

are now recorded for the first time from the British Area *, whilst a very considerable

number make their appearance for the second time only, ina British List. The total

number of species and varieties identified in the gatherings is 324. The material

_ consisted, with the exception of the small samples in spirit, of dried fine sands and

muds, without, as a rule, any notable admixture of shells or stones. Had these been

present in any quantity we have no doubt that the list of normally adherent arenaceous

and other forms might have been considerably extended. The dredgings, again, were

made in comparatively shallow waters, the greatest depth being 60 fathoms (at Stns. 16

and 21), which accounts for the absence of many deeper-water forms which might

have been expected from the area.

The bags were filled with great discretion by Miss Herdman, whenever the material

The most cursory glance at the above catalogue of material makes it immediately

plain that the Collectors have assembled a series of samples of the most diverse possible

kind and under the most diverse possible conditions, and a series which has consequently

amply repaid the-amount of labour that has been devoted to it. Bearing in mind

therefore what has been said as to deep-water and attached arenaceous and other forms,

the subjoined list of species may properly lay claim to being practically exhaustive

for the area under examination.

A few specimens at Stn. 19 and many at Stn. 18. The specimens at Stn. 18, which

are the best, are rather more compressed than is indicated in Wright’s figure—nearer, in

fact, to the specimens figured by Millett as biloculine forms of Wiliolina valvularis

(Reuss) (M. 1898, etc., FM. 1898, p. 501, pl. xi. fig. 6). Wright, in first publishing this

little form, placed it with B. ringens, but it appears to us to be more closely related to

B. irregularis, the aperture in the young forms of that species being similar but much

smaller.

Generally distributed, common at several Stns. The specimens are subject to great

variation. D’Orbigny’s original figure represents a shell laterally compressed (as con-

trasted with facial compression such as reaches its limit in B. depressa); Brady’s

examples show this compression in a less marked degree. The ‘ Runa’ specimens are

perhaps even more globular than Brady’s figures, although at many Stns. specimens

occur of a compressed habit; some of these show distinct traces of a third chamber

indicated externally, thus constituting a passage-form into Jiliolina. The young

specimens have, as a rule, characteristically small apertures with a slightly projecting

lip.

fully developed, and extremely typical and of all sizes.

The species was transferred by Schlumberger (S. 1891, BGF. p. 190, figs. 45, 46) to

the genus Planispirina on the ground of its internal structure, but in the present state

of our knowledge of the Miliolidz the transference does not appear to us to be desirable.

Very rare. The best specimens at Stn. 20. All the specimens are of an excavate type.

Spiroloculina acutimargo, var. concava, Wiesner, 1913, FAR. p. 521, No. 22

1 Station. A single specimen only.

Wiesner in his paper (wt supra) records this beautiful little variety, and, so far

as we are aware, it has not been figured or described in print. He was good enough to |

send us specimens of his variety from the Adriatic Sea, and its occurrence in these

dredgings is very noteworthy. As will be seen from our figure, the variety is very

striking and distinctive, being strongly convex on the one side and correspondingly

concave on the other. The whole test is exceedingly thin and delicate in structure.

The line of curvature is in the direction of the short axis of the shell. Wiesner

regards his specimens as a variety of S. acutimargo, Brady ; from the curvature of the

chambers it might equally be regarded as allied to S. tenuis. The reason for the curva-

ture of the chambers is entirely obscure; it may possibly, be due to the specimens

growing adherent to algz in the earlier stages of growth.

21 Stations.

Almost universally distributed, often abundant, and as usual very variable in character.

At some of the Stns., especially Stns. 6, 7, 8, 11, and 15, the specimens are very large.

At Stns. 7,12, and 15 they run wild, and at Stn. 12 this leads to the formation of

articuline forms, which also occur at Stn. 20. Similar articuline forms first attracted

the attention of Ehrenberg, who separated them under the name Ceratospirulina sprattii

(Monatsb, K. Ak. Wiss. Berlin, 1858, p. 19, and Abh. K. Ak. Wiss, Berlin, 1872), and of

Seguenza, who named them Quingueloculina tubulosa (S. 1862, RPC. p. 35, pl. i. fig. 8).

Subsequently Silvestri figured such forms under Ehrenberg’s name (Att. Pont. Acc.

Nuovi Lincei, Ann. 57, 1904, p. 189, fig. la-c). They are of fairly frequent occurrence

in dredgings in which the genus MWiliolina is prominent.

Fairly generally distributed. All the specimens are of the regular sharp-edged type,

except at Stn. 18, where the species is most abundant and reaches good dimensions. At

this Stn. also, and at Stn. 6, some of the individuals show a tendency to depart from the

usual regularity of construction and to approach JZ. (Triloculina) plicata of Terquem

(T. 1878, FIR. p. 61, pl. vi. fig. 3), recently figured by us from East Africa (H.-A. & E.

Much less abundant or widely distributed than the allied species J/. oblonga, but good

and typical examples occur at many Stns., especially Stn. 4. A thin-shelled opalescent

type occurs at Stn. 12, and more rarely at Stn. 18, similar to the hyaline specimens of

MM. oblonga referred to under that species. Previously recorded as British only by Mills

from the Humber (Trans. Hull Sci. ete. Soc. vol. i. p. 144, pl. x. fig. 17) and by us from

15 Stations.

Generally distributed, but not common, except at Stn. 18. At practically all the Stns.,

except Stn. 18, the majority of the specimens are typical, 7. e. they are of the square-

edged type foreshadowed in Montagu’s poor figure and represented by d’Orbigny’s Modéle

No. 95. At Stns. 7, 10, and 18 the curious “lidded”’ type figured by Williamson

(W. 1858, RFGB. pl. vii. figs. 186, 187) and referred to by us (H.-A. & EB. 1913, CI.

p- 25) occurs. At Stn. 18 great numbers occur of a very thin-walled opalescent form,

in company with the other types, but in greater number than either of them. In this

the aperture is flush with the ends, somewhat rounded and constricted, sutures flush,

and the whole shell practically cylindrical in section. The calcareous matter must form

a very small constituent of the test in this variety as they are practically transparent, and

apt to fall to pieces at the sutural lines when wetted or handled. This same type occurs

in many of the deeper ‘ Goldseeker’ dredgings off the west of Scotland and elsewhere.

Generally distributed and often common. The best specimens at Stn. 20, where a

complete range from typically quinqueloculine to spiroloculine specimens was obtained.

At all the other Stns. the specimens were milioline, though occasional compressed

individuals approaching the spiroloculine form were obtained. The spiroloculine forms

appear to be practically inseparable from Quinqueloculina tenuis (Czjzek), under which

name they have been recorded (cf. Spiroloculina tenuis, ante) for purposes of reference.

There can be no doubt that the two species are closely related. The species has

hitherto only been recorded as British by us from Clare Island (H.-A. & H, 1913, CI.

10 Stations.

The little form, which in the Clare Island report we assigned with some reservations

to d’Orbigny’s species, occurs at a good many Stns., most abundantly at Stns. 10 and 18.

We still feel some uncertainty as to the affinities of the form, but we see no reason to

vary the views we then expressed (wt supra). If anything, the ‘Runa’ specimens have a

greater tendency to a spiroloculine form than the Irish shells, but the specimens are so

variable (while preserving a superficial similarity of general characteristics) that we

prefer to retain the species. We are not at all satisfied with the Clare Island figures,

which fail to reproduce the opalescent character of the shell, and we take this opportunity

of figuring the species again,

We have failed to trace Brady’s type-specimens, on which the species was added to the

British list; they are not to be found either on the Brackish-water and Tidal River

slides (or, indeed, on any of the slides) at Cambridge, nor does the species occur on the

Brady type-slides in the British Museum. He quotes it as recorded by Siddall from

the River Dee, but we have searched the Siddall collection (which is now in our hands)

also in vain for the specimens on which the records rest.

strongly marked coste. Recent specimens, however, have, as a rule, but a very slightly

produced neck and numerous but not prominent costal ridges. ‘The species is abundant

This little form, which appears to be nothing more than a smooth type of WZ. bicornis,

is very sparingly represented in the dredgings, but good specimens and also adelosine

examples occur occasionally, the best at Stn. 18.

It should be noted that the synonymy of this species as given by us in our Clare

Island Report requires correction, the Quinqueloculina levigata of dOrbigny having

been confounded with his Adelosina levigata when the references were compiled. The

first two references to d’Orbigny, 1826, TMC. (ASN.), and 1839, FIC., should be removed

and the above synonymy substituted.

that the recent specimens differ structurally from the fossils originally described by

6 Stations.

Occasional specimens, free or attached. Very rare, except at Stn. 4, where the

specimens were numerous. As found by us they are nearly all detached, but have

evidently been sessile when living. They are large, rather thick-walled, consisting of

extremely fine and very friable white sandy material, the central cavity large and filled

with dried protoplasm. At Stn. 4 hardly any sponge-spicules or shell-fragments are

incorporated in the shell-wall, but at the other Stns. small foraminifera and sponge-

spicules form, as usual, a large proportion of the bulk of the test.

The question of the validity of Goés’s genus Crithionina as distinct from Schulze’s

earlier genus Storthosphera seems somewhat doubtful. Storthosphera is distinguished

_ by thick shell-walls, built up of fine sand-grains and without visible aperture, the

central cavity being large and undivided; Crithionina, on the other hand, is defined by

Goés as having the central cavity either labyrinthic or undivided. As the character of

the shell-wall is the same in the two genera, it would seem desirable that the species

of Crithionina with undivided cavity should be transferred to Storthosphera.

As a recent British species this has only been recorded by us from Clare Island and

the North Sea (ut supra), but we have numerous records of it from ‘ Goldseeker ’

dredgings.

specimens were very numerous and large, and justify the assumption that a colony of

the form occurred.

A few specimens at Stns. 4 and 21, in which each chamber was deflated and collapsed.

These specimens were constructed mainly of mica-flakes, in itself perhaps a sign of

to would be liable to similar distortion in most instances when removed from water.

Chapman’s record was from the Eocene of Hengistbury Head. It seems a useful

Test free, nautiloid, more or less depressed at the umbilicus, constructed of rather

coarse sand-grains and grey cement. As a rule, no septation visible externally. In

large specimens an occasional constriction indicates the presence of a suture. Marginal

edge thick and rounded. Aperture simple, ranging between a fissure and a constricted

terminal opening of irregular form. Viewed as an object in balsam the multilocular

character of the test becomes apparent; it is then seen to consist of three to four

convolutions divided.into numerous chambers (thirteen or fourteen in the last convolu-

tion) by septal walls that are usually very thin in comparison with the thick outer

wall of the test. The chambers are almost square in section.

This curious and obscure form occurs in some numbers at Stn. 17. It might easily

be overlooked, and regarded as a thick-walled and obscure variety of H. canariense

(d’Orb.), but the number and shape of tne chambers when viewed in balsam removes it

from any close relationship to that species. It bears considerable resemblance to the

Lituola nautiloidea, var. (Haplophragmium) depressa of Rupert Jones in the paper on

«The Deep Boring at Richmond” (Q.J.G.S. vol. xl. 1884, p. 765, pl. xxxiv. fig. 2), but

differs in the fact that the sutural lines are visible in the later stages of the rather

poor figure illustrating that variety, whereas in H. runianum they are only visible

externally under exceptional conditions. The nearest affinities of both H. runianum and

H. nautiloidea var, depressa are probably with HH. vrotulatum, Brady, as marked by the

concavity of the shell on both sides in the umbilical region, the thick marginal edge

and the obscurity of the septation, and numerous chambers.

Extremely common at Stn. 2, where the species occurs in all stages of development.

The specimens are, on the whole, very regular and typical in the arrangement of the

primary spiral, but at least one instance was seen at this Stu. in which the secondary:

spiral was suddenly diverted at a right angle before it had completely enveloped the

central initial spiral, thus giving the test the appearance of a globe divided into four

sections. A few specimens approached 4. gordialis in the irregular disposition of the

later convolutions. At Stn. 3 it was very rare and small. At Stn. 10 a single

- small specimen approaching A. gordialis. At Stn. 19 numerous specimens, many

worn as if washed from some distance. At this particular Stn. the final convolutions

in the large specimens were irregularly disposed. The comparison to 4. gordialis must

be considered as referring to the disposition of the chambers only; the constitution of

the shell is quite dissimilar, A. gordialis being built up of fine sand-grains with an

almost invisible proportion of cement, whereas in A. charoides the test is almost entirely

constructed of cement, sand-grains never being observable, even when the convolutions

are irregularly disposed.

Neither widely distributed nor abundant. Numerous excellent specimens at several

broader than the other, possibly representing the megalospheric and microspheric stages..

They are all grey in colour, the ferruginous tint being confined to the early part

of the test.

Cushman (C. 1910, etc., FNP. 1911, p. 70, fig. 111) has separated the specimens

figured by Brady from Berthelin’s original type under the name G. pseudo-filiformis,

apparently on the ground that the texture of the shell in Brady’s specimens and in

those dredged by the ‘ Albatross’ are smoothly arenaceous. ‘This appears to be entirely

insufficient ; the character of the chambers is practically identical with that shown in

Berthelin’s original figure, and the difference in the shell-texture of the ‘ Challenger ’

specimens with their increased proportion of cement is probably due to the greater depth

from which the specimens were obtained.

The species has been adequately figured by Wright (W. 1880-81, SD. p. 180, pl. viii.

If anyone wishes to realise the absolute impossibility of classifying Foraminifera on

the strictly rigid specific lines aimed at by zoologists working at higher groups, they

need only refer to the beautiful series of illustrations to Fornasini’s paper on the Adriatic

Buliminz (MASIB. ser. 5, vol. ix. pp. 371-881). After studying this plate and working

out such a series of dredgings as those under consideration, or, indeed, any series taken

234 MESSRS. E. HERON-ALLEN AND A. EARLAND ON THE

under similar conditions on a muddy bottom round the British Islands, the student will

ceme to the conclusion that it would be just as easy to name and figure twice as many

so-called “ species.” There are no definite and fixed features which can be laid hold of

as marking definite lines of separation.

Bulimina elegans is, however, a good starting-point around which to attempt some

classification of these protean forms.

The typical B. elegans is represented by a long and regularly tapering shell with three

definite series of smooth inflated chambers. Such individuals occur but rarely, although

present in limited’ numbers at most of the Stns. With a shortening of the spire and

increased inflation of the chambers we arrive at a somewhat broad and stumpy form

extremely common, and figured by Fornasini (oc. cit. pl. O. figs. 32, 34) under the name

B. gibba. If the aboral margins of the inflated chambers become salient, we obtain a

passage-form between B. elegans and B. marginata, to which Fornasini has given the

name B. gibba, var. marginata (figs. 22, 26, 35, 42, loc. cit.).

More than one Stn. of the ‘Runa’ gatherings, notably Stns. 19 and 21, consisted almost

of pure gatherings of Bulimine. We took the trouble to count a certain section of the

material from the latter Stn., and found the Buliminz to represent 98 per cent. of the

Foraminifera. Probably not 5 per cent. of the specimens could have been assigned

definitely to any specific type.

The variety ewilis is characterized by an extremely elongated test of the regular

Stns. ll and 17. They are, however, all small, compared with the development attained

by the variety in deeper and colder waters. The best specimens we have seen were from

comparatively shallow water in the estuary of the St. Lawrence River. The species has

been recorded by Wright from §.W. Ireland, by Worth from Plymouth, and by Pearcey —

from the Faroe Channel; but, as it has not been figured as a British species, we take

this opportunity of doing so (Wright, AMNH. ser. 6, vol. iv. p. 448; Wortb, J. Mar.

D’Orbigny’s species, as reproduced (ut supra) from the “ Planches inédites ” by Fornasini,

represents a Bulimina of the B. afjinis type, in which the aboral half of the shell is :

covered with a dense growth of short blunt spines, the remainder of the shell being —

smooth. D’Orbigny’s original finished “ Planche inédite,’ which we have carefully

examined, entirely justifies Fornasini’s figure, but d’Orbigny’s type-specimens, which we

have also examined in Paris, are so disguised in gum as to render their identification —

* The relationship of Dr Carlo Fornasini’s ‘Specie Orbignyane” to the “ Planches inédites” requires to be explained.

D'Orbigny was an indefatigable and accomplished draughtsman, and left behind him not only the “ Planches inédites ”

of the Foraminifera, but vast collections of similar drawings of fossils, all of which are now preserved in the

Director’s Cabinet at the Musée de Paléontologie in Paris. As early as 1819 we find his father writing to

M. Fleuriau de Bellevue that his son was making drawings of the “ céphalopodes microsecopiques ” which they had

discovered in the sands near La Rochelle (Jowrnal de Physique, 1819, vol. lxxxviii. p. 187). Later, when he began

to receive material from all over the world, he made a practice of first drawing the outline of all species as he

separated them, often roughly in pen and ink, under the microscope, indicating any surface-markings partially q

upon his sketch, and making notes on the rough slips containing the sketches. These sketches he subsequently

elaborated in sepia or Indian ink, making fairly finished drawings, which he in turn copied, drawing most delicately ;

and beautifully in pencil and water-colour on sheets intended, when complete, to illustrate all the species enume- .

rated in the ‘Tableau Méthodique.’ These constitute the ‘‘ Planches inédites,” which since 1826 have remained to a

great extent an unexplored and practically unavailable store of priceless information. We have made it our duty

to examine these ‘‘ Planches” in detail, Roughly speaking, there are 70 plates (7 unfinished) and materials for

finishing 79 more plates. We hope before long to arrange for the completion and publication of these plates ;

when it is done the names in the TMC. 1826 will no longer be for the most part nomina nuda.

The outlines published by Dr. Fornasini, scattered through some twenty-three memoirs and papers published by —

under the microscope) by M. Berthelin, and bequeathed by him to Dr. Fornasini under circumstances which the

latter has recorded (Rend. Sess. R. Acc. Sci. Ist. Bologna, 1897-8, vol. ii. p. 11, footnote). M. Berthelin appears

to have selected about 320 outlines for tracing, and these tracings Dr. Fornasini has carefully reproduced on a

fairly uniform scale. They cannot be said to compare for accuracy and heauty with the “ Planches inédites,” but

they afford a most valuable indication of what was in d’Orbigny’s mind when he founded his multitudinous and

often unidentifiable species.

This very beautiful species occurs in some numbers at Stns. 4, 10, and 12, and less

abundantly at the other Stns. At Stns. 10 and 12 many individuals had been dredged

in the living condition, and the protoplasmic body of the animal, which is of a bright

orange-colour without metaplastic enclosures, has in nearly all instances dried in clots

underneath the patches of clear shell-substance which mark the central portions of each

chamber. This probably indicates that the pseudopodial foramina are more or less

confined to these portions of the shell. B. swhéeres is, as a rule, very rare in British

dredgings, but, judging from the examination of ‘Goldseeker’ material, it increases in

frequency in the northern area.

panied in some instances by limbation of the sutures and coarse punctation. These

features combined often render the septal lines very indistinct. The best individuals

very distinctive forms occur, nearly always in company: (i.) along narrow form not far

removed from B. enariensis, and (ii.) a much shorter form which varies in two

directions—a thinner carinate form often having a denticulate margin and approaching

B. difformis, and a thick non-carinate type closely allied to B. robusta. The best

Reuss. At several Stns. there is a tendency to form either a marginal keel or serrate

processes at the extremities of the chambers; this is especially noticeable at Stn. 2. At

this Stn., and also at Stn. 4, many individuals twisted along the long axis occur.

Very scantily represented, but a few excellent specimens at Stns, 2 and 20. From

the examination of a long series of specimens at other localities, we have little doubt

that L. hispida is one of those species of Layena with compound shell-structure—

a. e., the shell-structure can be separated into distinctive layers. The internal layer is

normally clothed with a dense ‘‘ pile” of most delicate needles of equal length, and

their points coalesce to form a rough or “‘ mat” surface. ‘The spirally ornamented neck

is free from all exogenous growth. The “mat” outer surface is very easily destroyed ;

the spines then fall off, and only their bases are left, giving a faintly hispid surface

to the test—this is the stage in which British specimens are usually found. A still

further stage of attrition leaves practically no trace of the original spines, and a globular

test with a dull surface remains. We figure a specimen from the North Sea, which

illustrates the real nature of the test better than any of the ‘ Runa’ examples, which

are all in a more or less advanced stage of denudation of the outer layers.

Generally distributed, but not abundant except at Sts. 4 and 18. There are two

very distinctly recognizable types—one in which the flask is very swollen and rotund

and the other in which it is long, with more or less parallel sides. The two occur

together at Stn. 4 and at one or two others, but, as a rule, the narrow form predominates.

At Stn. 4a specimen of the rotund type with a hispid base occurred. At this Stn. and

also at Stn. 19 specimens were found in which there was a change in the diameter of

the shell at about mid-growth.

Almost universally distributed and often very common, the best at Stn. 7. Very

variable both as to size and prominence and regularity of markings. The var. interrupta

of Williamson occurs at many Stns. (W. 1848, BSGL. p. 14, pl. i. fig. 7), principally in

the shallower dredgings and shore-sands. At Stn. 2 a distorted specimen, with the neck

set almost at right angles to the body and with curved costz suggesting L. cwrvilineata,

Balkwill & Wright, was found; a somewhat similar specimen was found at Stn. 10.

At Stn. 19 a specimen in which the costz formed hexagonal reticulations over the base.

At Stn. 20 (and some others) a very small but strongly marked type occurs, with an

almost globular body and costee extending in sharp edges, and then coalescing into a

produced ornamental neck.

Less widely distributed and less abundant than LZ. williamsoni, except at a few Stns.

None of the specimens present the very salient ridges found in deep-water examples, but

at the same time the specimens asa whole are well and strongly marked, though varying,

especially at Stn. 10, in the prominence of the costz. L. acuticosta and L. williamsoni

must be extremely closely allied, for practically the only recognizable distinction between

the two forms lies in the fact that the neck in Z. acuticosta is a solid cone of shell-

substance, while in Z. williamsoni this cone is more or less covered with hexagonal pits.

Why tlie test with a solid neck should be more or less confined to deep water, while the

reticulate type has its habitat in shore-sands, is one of those puzzling problems of distri-

bution which baffle the student.

with few cost such as is usually found in British gatherings, but of a strong multi-

There is, as usual, a considerable range of form, specimens passing imperceptibly into

L. clavata, on the one hand, and into ZL. elongata (Ehrenberg), on the other. This latter

form occurs at Stns. 9 and 14, very long and tubular, the sides practically parallel for

the greater part of their length, but constricted at the extremities much more than in ©

Ehrenberg’s original figure of MJiliola elongata (BK. 1854, M. pl. xxv. fig. 1), which

probably represents a broken test. Fornasini’s note on this subject printed and

issued in 1895, which unfortunately was not published in any scientific journal,

This ubiquitous species occurs at nearly every Stn. and in its usual profusion of

forms. The best and most typical examples occur at Stns. 4,10, and 20, where the

species attains exceptionally large dimensions. Stn. 4 is also noteworthy for the

presence of a coarsely punctate form, which also occurs in lesser profusion at Stns. 14,

19, 20, and 23. This punctate form is very handsome, the shell-wall being usually

exceptionally hyaline. Trigonal specimens were recorded at Stns. 2, 5, 6, and 17, and a

polygonal example at Stn. 4. At Stn. 4, also, a specimen occurred with a large lipped

mouth opening on one side of the shell (compare the apertures in Sidebottom’s

LL. levigata (var.), 8. 1912, ete., LSP. 1912, pl. xvii. fig. 7). Specimens with similar

prominently lipped apertures occur in several of the ‘Goldseeker’ dredgings from the

This pointed form of ZL. levigata is widely distributed in the dredgings and very

abundant at some Stns. Few of the specimens present terminal spines of any size, in

the majority the base is merely ornamented with one or more blunted points. Two

forms occur—the commonest is a broad inflated test with a thick opaline shell, the other

narrow, long, and hyaline. A trigonal specimen occurred at Stn. 4.

More widely distributed than LZ. annectens and much more abundant, but very few

of the specimens are strongly marked. They run imperceptibly into the variety faba.

‘Typical examples should possess curving raised bands of shell-substance near the

marginal edge. Only one strongly-marked individual was found, at Stn. 21, and this

was decorated with rudimentary cost between the bands on the inferior portion of the

shell. Pedunculate specimens occur at Stns. 3 and 4. The species has only been —

recorded by us as a recent British form (H.-A. & EH. 19138, CI. p. 88; and 1913, NSH.

p- 184), but it appears in Wright’s list from Post-tertiary deposits at Magheramore

This is the most widely distributed and abundant type of its group in the dredgings, ~

occurring at most Stns. and often in considerable numbers. It differs from L. fasciata

in the reduced prominence of the marginal costz, which are but very slightly raised, —

and are of a milky texture as in ZL. annectens, thus occupying a position midway

between ZL. annectens and L. fasciata, but its most permanent characteristic appears to

be the surface-texture, which was compared by its author to orange-peel, and appears

to be a constant feature.

as in Ff. schlichti. At Stn. 11, two trigonal individuals were found, but no normal

at Stn. 3. Two forms varying in the convexity of the test are especially noticeable—

a biconvex type, which is the commonest, and a flat-faced type, occurring principally at

Stns.3.and10. This flat variety appears to be subject to more abundant keel-growth

than the convex form. Many trigonal specimens at Stn. 10 and a few at Stn.12. At

The original diagnosis of this species is confusing. Brady described it as having

“ characters as in L. marginata, W. & J., to which it is closely allied, but differing in

having a number of delicate parallel costze springing from the base and extending into

the upper half of the shell, in some specimens nearly to the aperture,” but gives no

figure [Brady, Brit. Assoc. 1866 (Hebrides, 1867), p. 70]. Later (wt supra) he repeats this

description without amplification, but figures a trigonal test of the group of L. orbignyana

(not LZ. marginata) with sinuous and branching costz. Balkwill and Millett in 1884

(B. & M. 1884, FG. p. 32, pl. il. fig. 13) set the matter right by figuring a specimen

similar to Brady’s, and describing it as “a variety of L. orbignyana, the surface marked

with branching costz.” This was followed by Balkwill and Wright, wt supra.

LL. pulchella occurs abundantly in some of the ‘Runa’ dredgings, although the records

are confined to a limited number of Stns. At Stn. 20 it was excessively common.

Nearly all the specimens are extremely strongly marked, contrasting markedly with the

allied species LZ. clathrata, which is almost invariably a feeble type in the dredgings.

This species was instituted by Brady (wt supra) for the varieties of L. orbignyana in

which the faces are marked with parallel longitudinal coste as contrasted with his

earlier species, Z. pulchella, in which the costz are sinuous or branching. It is more

widely distributed in these dredgings than ZL. pulchella, but the specimens are fewer

in number and almost invariably of a weak hyaline type, with feeble costz seldom

extending over the whole face of tle shell. It reaches its maximum development,

like L. pulchella, at Stn. 20. The species has only been recorded as recent by Balkwill

and Millett from Galway (B. & M. 1884, FG. p. 82, pl. iil. fig. 14), and by Wright

from Dog’s Bay (W. 1900, DBC. p. 54), and ourselves (wt supra), but it has probably

been frequently included under Z. pulchella, of which there are many British records.

A few individuals only. The faces of the tests, which we figure, are regularly pitted,

but the markings have neither the regularity nor the uniformity of shape characteristic

of normal typical specimens. They may be due to algal or fungoid perforations, and

Two specimens, one of which we figure from Stn. 4 and another from Stn. 17, are,

we think, attributable to Sidebottom’s species, although broader in proportion to their

depth than his figures. The species is probably subject to very great variation—indeed,

Sidebottom refers to this in his description. We figure, for purposes of comparison, a

few specimens from Noss Head, Moray Firth (‘ Goldseeker, Haul 1388, 70 metres), where

the species occurs in some profusion, and is extremely variable in the breadth of the

shell as compared with the depth.

- Generally distributed, but never very common, the specimens usually small, thin-

shelled, and weak, but large and fairly typical specimens at Stns. 3 and 20. Two

distinct forms occur, sometimes together, but often isolated—the normal round-in-section

N. communis and a compressed or vaginuline form. The latter often develops in its

later chambers into the normal round type. ‘The best examples of the vaginuline type

were at Stns. 4,18, 20, and 21. Monstrous or double or distorted specimens, showing

double or distorted primordial chambers, occur at several Stns., notably at Stn. 18, and

are referable to both forms. The vaginuline or compressed form is very common in

Almost universally distributed and by far the commonest Nodosaria in the dredgings,

but not equally abundant at all the Stns. The finest series at Stns. 4, 10, 14, and 18.

The typical form of Batsch, with chambers regularly increasing in size and coarsely

sulcate, is not particularly abundant, but Stn. 18 yields an exceptionally fine and large

example, with no less than seven regularly increasing chambers; other good examples

at (inter alia) Stn.14. From this typical form practically every degree of depauperation

exists down to almost smooth examples. These latter occur at Stn. 4. The weakly

marked variety named by Silvestri Lagenonodosaria pseudoscalaris (Atti Pont. Acc.

Rom. Nuovo Lincei, Anno lvii. 1904, p. 144, fig. 4), characterized by few and feeble

costze and a more or less distorted shell, occurs nearly everywhere. A variety with

practically parallel sides, 7.e., showing no increasing diameter in the chambers, occurs

at Stns. 4, 14, 20, and 23. Ineequilateral types, in which one side of the shell is

developed at the expense of the other, giving an Amphicoryne appearance to the test,

258 MESSRS. E. HERON-ALLEN AND A. EARLAND ON THE

occur at Stns. 5,12, and 21. At Stn. 14,a single example of the Batsch type was found,

in which the produced neck was exceptionally thick and studded with spines, a form of

growth usually found in deeper water. Bicamerate specimens are widely distributed at

many Stns., and at Stns. 6, 16, and 19 were the sole representatives of the species. In

many instances, these bicamerate individuals were of large proportions, indicating that

they were not young shells, but a distinct local variety in which growth was normally

arrested at this stage.

At Stn. 4 a few little specimens, which we figure and which we think should be

attributed to this form, although, owing to their extreme minuteness and hyaline

character, they differ considerably from the large deep-water specimens figured by

Brady from the Atlantic. The test is bilocular, the last chamber forming quite three-

fourths of the total bulk of the shell, and furnished with a long curving entosolenian

tube, which runs diagonally to the lower outer edge of the chamber. The margin of

the entire shell is thickened and slightly constricted on its inner edge, so as to form a

fine groove running round inside the edge of the shell. These markings we consider

homologous with the sulci of the deep-water form.

At Stn. 26 (a tube of material labelled “from various localities round Skye”’) we have

found the specimen which we figure under the above name. As to the origin of the

specimen there must be considerable doubt. Bornemann’s species in one or other of its

innumerable forms is apparently a common and widely-distributed Liassic fossil, but

there appears to be no Lias within a great distance of Skye. The specimen, although

somewhat infiltrated, cannot be distinctly recognized as fossil—it might be merely a

dead recent shell. It consists of a large primordial chamber followed by six chambers,

regularly increasing in breadth and but slightly arched, although we think the arching

sufficient for its allocation to Frondicularia rather than to Lingulina. ‘The surface of

the shell is concave down the median line, and each edge is furnished with four strong

costze, extending the entire length of the shell. The aperture is broad and slit-like.

Brady’s recent species F. milletéii, founded on specimens from coral-sand (Raine Island),

appears to differ from F. fenera only in the greater number of chambers and the

character of the terminal aperture on a produced neck, and the large number of

marginal coste. The range of varieties illustrated by Terquem’s F. pupa (ut supra)

_ more than covers these points. His figure 1 ¢ appears closely to resemble both our

specimen and Brady’s species in all but minor details. As a fossil the form has been

recorded under the name of Lingulina tenera from the estuarine clay of Limavady

Station and from the Lias of N.E. Ireland (W. 1880, NEI. p. 150; and Wright, Irish

Liassic Foraminifera, Belfast Nat. Field Club, 1871, App. ii. p. 26).

range of variation in the specimens which have to be referred to this species. At many

Stns., notably Stns. 2, 4, and 20, the specimens in their regularity of growth approach

C. eymboides, V@Orb., and C. acutauricularis. At Stns. 3, 12, and 20 large individuals

of the compressed type of C. arcuata, d’Orb., occur. The majority at all Stns. are

perhaps more than in any other.

Occurs at very few Stns. and nowhere typical. All the individuals are of a narrower

type, as viewed across the face of the terminal chamber, than in Fichtel & Moll’s original

plates. They thus approach C. cymboides, dOrbigny. At Stns. 4 and 20 some of the

specimens were almost typical C. cymboides. This species has only been recorded as a

recent British form by us from Clare Island and the North Sea (H.-A. & E. 1913, CI.

p- 99, pl. viii. fig. 15), but Wright has recorded it from Post-tertiary deposits in the

North of Ireland (W. 1910-11, ECM. p. 15). It has probably been included by many

authors under C. crepidula, which, as Burrows and Holland have observed (Proc. Geol.

At Stn. 4 two minute and thin-walled specimens of a Cristellaria were found, which

we are inclined to refer to Bornemann’s species, and a single one at Stn. 20.

Bornemann’s figures are in themselves unsatisfactory, fig. 16 representing a rotulate

form with no visible septation ; whereas fig. 17 represents a form evidently allied to

©. gibba and having marked septal lines. His fig. 18 (on same plate), C. elliptica,

illustrates a form linking figs. 16 and 17, and C. elliptica is properly regarded as a

synonym of C. convergens.

The two ‘Runa’ specimens represent the two types figured by Bornemann in his

figs. 16 and 17, but, as might be expected in such shallow water, the specimens

are small and the shell-texture thin and extremely hyaline, so that the septation is’

distinct in both individuals.

C. convergens is normally a deep-water type. Brady’s records range between 16 and

2740 fms., the majority being in the neighbourhood of the 2000-fm. line. As a recent

British species it has only been recorded by Pearcey from the Firth of Forth (Trans.

Nat. Hist. Soc. Glasgow, NS. vol. v. 1900-1, p. 242).

Widely distributed, but never very abundant. Taking P. sororia as the type of the

pyriform Polymorphinze, Reuss’s species should properly be confined to the compressed

forms, and d’Orbigny’s earlier species, P. gutta (d’O. 1826, TMC. p. 267. No. 28, pl. xii.

figs. 5, 6, Modéle No. 30) and P. (Pyrulina) acuminata (a’O. 1840, CBP. p. 43, pl. iv.

differences are, in our opiniun, too trivial for consideration, and the compressed type

being by far the most abundant we prefer to separate all such forms under Reuss’s name

P. sororia.

Typical P. sororia occurs practically at every Stn. Round (=P. gutta) forms at

“Stns. 2, 4, 12, 18, and 20, the best at Stn. 20. Pointed (=P. acuminata) forms are

1 Station.

We figure a single specimen from Stn, 14 of an organism which from the character

of its aperture seems to present some affinity to Spherotdina.

It consists of two chambers only, opposed to each other, in the manner of Biloculina

bulloides, with a little arched aperture on either face at the line of junction. The shell

in the neighbourhood of the two apertures is smooth and hyaline, but the rest of the

shell, which forms a slightly compressed sphere, is coarsely aculeate. It may be an

abnormal individual of S. bulloides, in which the early chambers have been absorbed

and the outer surface is decorated with blunt spines.

We record and figure this single specimen for purposes of future reference, without

naming it.

At this Stn. and in this condition associated pairs were found. Specimens exhibiting a

transition-form between S. vivipara and S. margaritifera, which we figure, occur at

several Stns. They agree with the Type S. vivipura in the section of the tube and

general aspect of the shell; but the underside of the shell is distinctive, the shell-substance

being deposited in thick layers on the outer edges of the convolution and coming down

into cusps between the lines of perforations, thus giving a pseudo-beaded (or margariti-

ferous) appearance to the inferior surface. In some cases this is accompanied by a

radial constriction of the upper surface of the tube corresponding to the thickening of

the under surface, giving a superficial aspect similar to Sidebottom’s species S. viripara,

owing to the presence of a central umbilical stud, and into D. rosacea through the

presence of small asterigine chamberlets, occur at many Stns. At Stns. 10 and 20 a few

individuals of a type with somewhat inflated and enclosing chambers, which we figure

(figs, 29, 30): this variety is characterized by a lobulate periphery instead of the sharp

peripheral keel typical of the species. At Stn. 20 a few individuals were observed of a

very curious type, which we also figure (figs. 26-28), having a comparatively high dome

with a prominent megalospheric primordial chamber and a broad carinate periphery.

_ a rosette of beads at the umbilicus and lines radiating from them. JD. baccata, on the

_ other hand, has, in perfect specimens, a characteristic rough or ‘shagreened” (or

beaded) surface all over. Of course, Terquem’s figure and description may have been

based on dead and water-worn shells, and, as his specific name has been appropriated

_ and used for thirty years for a very distinctive type of Balkwill and Wright (B. & W.

Generally distributed, often abundant. All the individuals are of the small pauperate

hyaline type widely distributed in shallow waters round the British coast. We now

figure this variety for the first time, for, although there are many British records, no

attempt to reproduce this pauperate form has been made.

The carliest British record of the species is in Brady’s ‘Fauna of the Shetlands ’"—

FORAMINIFERA OF THE WEST OF SCOTLAND. 277

“three or four small starved specimens” (B. 1864, RES. p. 470, pl. xlviii. fig. 15).

Instead of figuring these specimens as should have been done, Brady reproduced Reuss’s

original figure (wf supra) from the chalk of Mecklenberg. These fossils are of the

robust type, with strong marginal edge and deep sutural lines on the base, such as

are commonly found in deep water. Brady’s original Shetland specimens appear to

have been lost; we cannot find any trace of them at Cambridge, Neweastle, or the

British Museum, but there can be little doubt that they were similar to the little form

which we figure, and which is quite common in the Shetland area. A slide in the

Cambridge collection among the N. Polar 1875 Expedition slides contains small speci-

mens, which, but for the rather strong sutural lines, are identical with the familiar

British type.

A single specimen which we figure from Stn. 6 presents the essential characteristics

of this species in its flat superior face, conical inferior face, and strongly limbate sutural

lines, but it has only seven chambers in the final whorl, each chamber being considerably

longer than is the case in the large tropical specimens on which the species was founded.

The occurrence of a specimen in a British gathering is very startling, the records of

the species being confined to tropical shallow water, where it attains a very large size. —

It may, of course, be nothing more than a local ‘‘ sport”’ from R. beccarii ; but, if so, its

assimilation of the characteristics of another typical species is equally remarkable.

Parker and Jones’s species appears to be merely a compressed and broadened form of

the Gyroidina conoides of d’Orbigny (d’O. 1826, TMC. p. 278. No. 9), of which we have

examined the type-specimens both at Paris and at La Rochelle.

23 Stations.

Almost universally distributed, abundant at many Stns., and, as usual, subject to

excessive variation, due primarily to the character of the sutural lines, which are some-

times depressed and sometimes limbate. The best examples of typical W. depressula

occur at Stns. 5 and 22.

Among the most noticeable and constant varieties is one which we figure, and which

forms the principal feature of Stn. 17, characterized by deeply excised sutural lines; in

some cases the marginal edge is scolloped as a result of this feature. The umbilical

portion of the shell is filled in, sometimes a stud of solid shell-matter appearing in

the centre. This appears to be the Nautilus spiralis of Walker and Boys (W. & B.

1784, TM. p. 19, pl. iii. fig. 68). It occurs in smaller numbers at many other Stns.

Another widely distributed variety is characterized by a biconvex hyaline and strongly

punctate shell with limbate sutures. This is the form to which we have referred in our

Kerimba Mongraph (H.-A. & E. 1914, etc., FKA. 1915, p. 730). Monstrous specimens

20 Stations.

Almost universally distributed and often very common. There is a certain amount

of variation due (i.) to the degree of turgidity in the growth of shell, and (ii.) to the

degree of envelopment of the chambers of the final whorl. In young specimens there is

no depression at the umbilicus. With increase in size, if the shell continues of the non-

turgid type, the whorls are almost entirely embracing, so that the umbilical region

remains either almost flush or very slightly depressed. If the chambers are of the

turgid type approaching NV. pompilioides (F. & M.) each successive convolution becomes

less enveloping, so that the umbilicus becomes deep; and at some Stns. the successive

later whorls are undercut, exhibiting two entire convolutions in the centre of the shell.

Distorted specimens occur at Stn. 18.

NV. stelligera is a very distinctive form of the N. depressula group, characterized by

inflated chambers due to the depressed sutural lines. The umbilical portion is clearly

marked out by a stellate process radiating down each sutural depression, sometimes

almost to the marginal edge. This stellate process is in its highest development almost

a secondary series of chambers, due to the partial overlapping of its predecessor by each

successive chamber in the convolution. Occasionally this overlapping “star,” instead

of being a hollow chamberlet, is a solid mass of shell-substance, in which case we get a

solid radiating stud or a stellate limbation.

Far commoner than the true XN. stelligera is a form which closely resembles it

in superficial appearance, 7. e. with swollen chambers and sunken sutural lines, with

radiating stellate ornament, but the ornament in this case is merely superficial and

masks rudimentary retral processes. We have separated this form under Polystomella

Saba (F. & M.).

Fichtel and Moll’s description indicates a pauperate form intermediate between

Novionina and Polystomelia, but referable to the latter genus on account of its retral

processes. Their figure, however (of which we possess Moll’s original water-colour

drawing), gives no indication of the Polystomelline affinities, such as are plainly referred

to in their text, and are shown in Parker and Jones’s woodcut (w¢ supra), which is repro-

duced from their previous work (P. & J. 1865, NAAF. p. 402, pl. xiv. fig. 36). Two

distinctive types occur in these dredgings, both of which, we think, should be placed

under Fichtel and Moll’s species, although differing in certain respects. The first or

compressed type, which is nearest to P. faba, has somewhat inflated chambers of an

involute type, six or seven visible in the final convolutions; sutural lines curving and

strongly depressed, filled with fine granular matter radiating from the umbilicus down

the sutures, and giving a stellate appearance to the test, owing to the whitish granu-

lations contrasting strongly with the hyaline surface of the chambers. It closely

resembles Nonionina stelligera superficially, and is probably responsible for many

British records of that species, as it is widely distributed round the British coast,

whereas true NV. stelligera is rare. The retral processes, which are few in number, are

282 MESSRS. E. HERON-ALLEN AND A. EARLAND ON THE

masked by the secondary shell-matter, but become visible when wetted. The second or

turgid type, which occurs abundantly at Stn. 22 and elsewhere, is much larger, the

chambers being less inflated and more numerous, ranging up to eight or nine in the

final embracing convolution ; sutural lines depressed, but less so than in the compressed

type, and filled with the same granular matter radiating from the depressed umbilicus,

but to a lesser degree. The retral processes are much more numerous than in the

compressed type, and, although rarely visible in the dry shell, come out strongly when

wetted.

The compressed type is evidently to some extent isomorphous with NV. scapha (as

observed by Fornasini) and the turgid with NV. depressula. Both forms represent

connecting-links between the two species and P. striato-punctata, as also does P. de-

cipiens, though on a different line of development.

321. Polystomella arctica, Parker & Jones.

Polystomella arctica, Parker & Jones, MS.; Brady, 1864, RFS. p. 471, pl. xlviii. fig. 18.

. is Brady, 1884, FC. p. 735, pl. ex. figs. 2-5.

8 Stations.

Rare, and the specimens few in number, rather small, and generally worn. The best

specimens were at Stn. 22.

322. Polystomella macella (Fichtel & Moll).

Nautilus macellus, Fichtel & Moll, 1798, TM. p. 66, pl. x. figs. e-g.

Polystomella macella, Brady, 1884, FC. p. 737, pl. ex. figs. 8, 9, 11, & ? 10.

18 Stations.

Widely distributed, but never very abundant, the best at Stns. 3, 4, and 17. The

chief variation lies in the relative depression of the septal lines, which in some cases are

so depressed as to give a turgid character to the chambers. These turgid specimens

are, as a rule, characterized by a granular deposit over the shell-substance. At Stns. 6

and 8 the specimens were intermediate between P. macella and P. crispa.

323. Polystomella crispa (Linné).

Nautilus crispus, Linné, 1767, SN. p. 1162. No. 275.

Polystomella crispa, Brady, 1884, FC. p. 736, pl. ex. figs. 6, 7.

21 Stations.

Almost universally distributed, but never common. ‘The specimens are, as a rule,

large and handsome and of the compressed type. At several Stns., notably at Stns. 4

and 17, the marginal spines persist to an advanced or even mature stage (see H.-A.

& HE. 1913, CI. p. 146, pl. xii. fig. 14). Distorted specimens occur at Stns. 5, 11, and

notably Stn. 15, usually due to fission of the protoplasm separating into two distinct

shells at about half the growth, the subsequent growth being continued on two distinct

planes.

Subfamily NUMMULITIN&.

OprERCULINA, d’Orbigny.

324. Operculina ammonoides (Gronovius).

Nautilus anmonoides, Gronovius, 1781, ZG. p. 282. No. 1220, pl. xix. (fase. iii. tab, 2) figs. 5, 6.

Operculina ammonoides, Brady, 1884, FC. p. 745, pl. exii. figs. 1, 2.

20 Stations.

Almost universally distributed, often very common, the best specimens at Stns. 4,

11, and 14. Variation is almost entirely dependent on the degree of limbation of the

sutures, which at some Stns. is very marked and striking. Distorted or wild-growing

forms occur at Stns. 19, 20, and 21. At Stn. 19 there is a tendency to an inflation of the

later chambers.

FORAMINIFERA OF THE WEST OF SCOTLAND. 291

BIBLIOGRAPHY.

An effort has been made to reduce the synonymies prefixed to the three hundred and twenty-four

species and varieties described in this Report to a minimum of space. The principle first adopted by

us in the Clare Island Monograph (H.-A. & KH. 1913, CI.) has therefore been followed here, and with

very few exceptions the original reference to the author of a species has been given with one later and

well-illustrated record. In all cases where the species is illustrated in Brady’s ‘Challenger’ Report

(B. 1884, FC.) that reference has alone been given in addition to the original. Where the species has

not been included in, or has been diagnosed subsequently to, Brady, 1884, FC., one later reference—if

possible, British—has been given.

Names of authors, titles of articles, and full bibliographical references to the Transactions and

Proceedings in which they are to be found are given once and for all in this Bibliography, some lengthy

titles being shortened as follows :—

QJGS.= Quarterly Journal of the Geological Society, London.

JRMS.=Journal of the Royal Microscopical Society, London.

JQMC.=Journal of the Quekett Microscopical Club, London.

MASIB.=Memorie della Reale Accademia delle Scienze dell’ Instituto di Bologna.

SAW W.=Sitzungsberichte der Kaiserliche Akademie der Wissenschaften Wien. (D=Denkschrift.)

AMNH.=Annals and Magazine of Natural History.

The titles of all papers and books are indicated by initials only, after the date of publication, and the

first letter of the author’s name :—thus, C. 1892, PCT.=F. Chapman, ‘ Microzoa from the Phosphatic

Chalk of Taplow,’ the page, etc., only being given, and all further details being found under that initial

and date in the Bibliography. In the case of long or short series of papers, the date of the first is given

and the initials are followed by the vear in which the paper referred to appeared: thus, M. 1898, etc.,

FM. 1900 = the papers of Millett’s series, beginning in 1898, which were published in JRMS.
