TUBICOLOUS AMPHIPOD CHILTON.

On a TUBICOLOUS AMPHIPOD from PORT JACKSON. By Chas. Chilton, M.A., B.Sc.

[With Plate I.]

Among some Australian Crustacea sent me as exchanges by the Trustees of the Australian Museum was a tube-dwelling Amphipod collected in Port Jackson. There was a plentiful supply both of specimens and of the tubes formed by them and after a full examination and comparison of them with Mr. Stebbing's des- cription and figures I have no doubt that they belong to Cerapus Jiindersi, Stebbing,* a species described from a single female specimen taken in Flinder's Passage during the voyage of the "Challenger." Mr. Stebbing says nothing of the tube in his descrip- tion, and I presume therefore, that he has not seen it. I am now able to supplement his description in this respect and also to describe the male of the species, and to give the points in which it differs from the female, and also some interesting facts on the changes in form that occur during the growth of the male.

The genus Cerapus was originally established in 1817 by Say, and the species Cerapus hihularis was afterwards fully redescribed in 1880 by S. I. Smith who established for it a new sub-family CerajnncB in the family Corophiidce.j He thus describes the new sub-family :

" The single known genus differs from the Podocerince and allied groups in the following characters. There are only three pairs of branchial lamellfe, which are borne on the third, fourth and fifth segments of the perseon, and only three pairs of ovigerous lamellae, which are borne on the second, third, and fourth segments. The second and third pleopods are much smaller than the first, and their inner lamellfe are rudimentary or very small. The second and third uropods are uniramous and nearly alike, the distal extremity in each being short and terminating in a hooked joint.

" The only known species inhabits unattached, portable tubes, and, as in many allied genera, has large cement glands in the bases of the first and second perjeopods."

The above quotation has been taken from Stebbing's " Report on the " Challenger " Amphipoda," as I am unable to consult Professor Smith's original paper. I am therefore unable, also, to compare the present species in detail with Cerapus iubularis, Say. The " cement glands " in the first and second pereiopods have been

very fully investigated by Nebeski,* but for this reference again I am indebted to Stebbing's report.

In addition to our present species Stebbing has described another new species Ce7-apus sismithi, taken during the Challenger Expe- dition at Kerguelen Island, f

In the following detailed description of the various parts of the animal I have omitted all those parts where I had nothing to add to Mr. Stebbing's description.

Head and body. The head is produced anteriorly into a sub- acute rostrum between the bases of the antennte, much in the same way as is shown in Mr. Stebbing's figure of Cerajius sismithi, but in none of my specimens have I noticed the rostrum to be " carinate " as it is drawn and described by Mr. Stebbing in C. Jlindersi. (See figures A and B.)

The relative lengths of the various segments of the pereion of the female agree well with Stebbing's description, but in the male they are quite different. In this (see fig. B.) the first segment is about as long as the head, the second is slightly longer, anteriorly it is slightly narrower than the first segment, but about the middle it suddenly widens to twice this width thus giving attachment to the large and powerful second gnathopoda ; the third segment is considerably shorter than the second and is also narrower anter- iorly but it widens posteriorly ; the fourth is shorter again than the third, as wide anteriorly, but narrowing posteriorly ; the fifth segment which is so long in the female, is only a little longer than the fourth and not so long as the third ; the sixth is subequal to the fifth in length and breadth; the seventh is as broad but shorter.

Upper Antennm These agree on the whole with Stebbing's description, but the first joint of the peduncle is not " much longer than the second joint "; it is usually about the same length and in large specimens may even be somewhat shorter. The flagellum may contain as many as seven joints, usually there are more than four, the number given in Stebbing's description. (See fig. a. s.)

Lower Ante7ince. These also differ in a few details. The fourth joint is not " dilated at the base," nor " abruptly broader than the preceding joint " in any of the specimens that I have examined, indeed the fourth joint is usually narrowed a little at the base and it articulates with only a portion of the end of the third joint so that the articulation is not very strong and the fourth joint is very freely movable upon the third. (See fig. a. i.)

TUBICOLOUS AMPHIPOD CHILTON. 6

In large sized males the lower antennse are stouter and more pediform than in younger specimens, and the long setse are by no means so conspicuous.

The mouth parts appear to correspond closely with Stebbing's description, but I have not examined them in great detail.

The first gnathopoda are the same in both sexes and agree with Stebbing's description as closely as can be expected when allowance is made for individual variation.

The second gnathopoda differ very much in the two sexes. In the female they do not differ very greatly from the first gnathopoda and agree very closely with the description already given by Mr. Stebbing. I give a drawing for the sake of comparison with the second gnathopoda of the male, (see fig. gn. 2 ? ). In the male the second gnathopoda differ considerably from those of the female and also differ very much at difterent stages in the development of the same individual. The form most commonly met with is that shown in fig. gn. 2 ^ B, which represents the second gnathopod of a moderate sized male; it will be convenient to describe this first.

The first free joint, the hasos, is narrow at the base where it articulates with the moderate sized side-plate but rapidly widens until at the widest part it is more than half as broad as long ; the anterior edge is straight except near the base and is fringed with about ten spinules, the posterior margin is strongly convex and bears two or three setas at the apex ; the ischios and the meros are of the usual shape and not unlike those of the female ; the meros has the distal extremity produced, rounded and tipped with a few setpe ; the carpus is very large and broad, its anterior mar- gin very convex especially towards the base, a small group of sette* at its distal extremity, the posterior margin is indistinctly serrate and bears five groups of long setse in the serrations, other shorter setfe are situated between the serrations and a few on the surface of the joint ; the postero-distal corner is pi'oduced acutely and reaches about half way along the inner mar-gin of the propodos, and between this corner and the inner articulation of the propodos is a short rounded lobe reaching only about half as far. The propodos is considerably shorter than the carpus, rather more than twice as long as broad, the anterior margin curved and bearing about six spinules, that at the apex the longest ; the posterior margin with the basal half smooth, but the distal half minutely serrate or more strictly speaking crenate, the whole margin fringed with abundant long setse, a few others being situated along the surface of the joint ; the dactylos is like that of the female and has the inner margin denticulate towards the distal end, but the inner margin of the terminal tooth again is smooth.

* These serrations are not shown very distinctly in the plate.

In one large and evidently old male, about J inch in length, the second gnathopod was much elongated and at first sight ap- peared very different. A close comparison shows however that it is simply a more developed form of the gnathopod just described, and that the two are not dimorphic forms. The whole limb is much elongated and the set?e are fewer and much smaller in pro- portion ; this loss of setpe was also noticeable in the antennte and I have noticed examples in several other species which seem to show that it is a change that very generally accompanies age and increase of growth.

The side-plates (epimera), (see fig. got. 2 ^ A) are small and are produced anteriorly into a moderately acute process which bears two or three seta? ; the basos is of the same general shape as that found in the younger male but is much narrower, the ischios and meros are also similar but more elongated and the setse at the end of the meros are very few and small ; the carpus is immensely elongated and consequently much narrower in propor- tion, it is narrow towards the base and widens again distally, the anterior margin is quite free from setaj except one or two very small ones at the apex, the posterior margin is straight with five distinct serrations, in each of which are two or three short setaj ; the extremity is produced into two long processes about half as long as the propodos, the process formed of the postero-distal corner having the sides parallel and the end truncate, the other, corres- ponding to the small rounded lobe in the younger male, with the outer margin straight, inner margin slightly concave, extremity rounded, quite free from set;e ; the propodos is very long and narrow, the breadth not more than one-fifth the total length, the whole joint is much curved inwards, the inner margin being very concave and fringed with a row of scattered setaj ; the finger is stouter and blunter than in the younger male and has the inner margin smooth. The propodos is not movable quite in the same plane as that of the carpus, but bends back on one side of it so as to lie obliquely along its surface.

I have seen only one very large male with the second gnathopoda like that shown in fig. gn. 2 ^ A. Most of them were more like the one represented in fig. gn. 2 ^ B, but in some the two pro- cesses at the end of the carpus were a little more developed, in others a little less developed than those shown in this figure. Forms younger still than that represented in fig. gn. 2 ^ B would no doubt approximate more closely to the female in the form of second gnathopoda.

Tlie first pereiopoda agree closely with the description given by Stebbing, but I have not observed the " long transverse slit " across the surface of the basos that he mentions.

The second pereiopoda also closely resemble Stebbing's descrip- tion. In both this and the preceding pair the side plates are

produced antei'iorly into a small rounded lobe tipped with setae, that of the first pair being considerably larger than that of the second.

The third pereiopoda have the side plates very large, delicate and membranaceous. Those of the female are very much larger than those of the male, a fact which tends to confirm Mr. Stebbing's supposition that they fulfil the function of marsupial plates. The side plates extend along the whole segment forming a small lobe in the rear and are of about uniform depth, the two lower corners being broadly rounded, the lower margin being usually slightly concave in the middle. The margin is somewhat uneven, entire or irregularly crenate, and is irregularly fringed with setaj. The rest of the limb is attached to the side plate at the rear and usually projects directly backwards. The relative sizes of the side plates as compared with the rest of the limb in the two sexes can be seen by comparing figures prp. S ^ and p7-p. 3 ? . The other joints of the limb are practically identical in the two sexes and agree closely with Stebbing's description.

The fourth ^jereiopoda have the branchial vesicles very small, narrow and bent at the base. The whole limb is much as described by Stebbing, but is usually
