Challenger During the Years 1873-76 The species of Lepas, the Cypris-larvae of which have served me for comparison, was the Lepas austmlis, Darwin. It is not only very characteristic on account of its great size, but it is also the best known Cypris-larva, as it served first for the investigations of Darwin, and again some years ago for the studies of Claus. The latter has given a very good figure of the internal structure of this larva as seen in a sagittal section. My figs. 1 and 2 on pi. II. Very closely correspond to that of Claus. My fig. 1 was drawn from a preparation made by dividing the body of the Cypris-larva of Lepas australis into two nearly equal halves by means of a sagittal section. The rounded spot (a M) is the adductor muscle of the two valves of the Cypris-larva the straight line at the under side of the valve represents the ventral side, the convex one the dorsal side; the extremity on the left of my figure the frontal (cephalic), the one facing it the hinder (abdominal) extremity of the body; from the way in which the spines of the legs are stretched out at the ventral side it is clear that there is a slit-like opening between the adductor muscle and the hinder extremity of the body. In fig. 2 of P]. I., representing a longitudinal section parallel to and at a little distance from the ventral margin, this orifice is also distinct. This is the only place where the interior of the sack or mantle (as Darwin calls it) is in open communication with the surrounding water. The body of the future Lepas is enclosed within the sack and has also a wall of its own; on one side (the right hand side of the figure) this wall is very distinct, and it passes over near the middle of the dorsal margin into a transverse invagination which almost reaches up to the ventral side. It is by this invagination that the division of the body into a capitulum and a peduncle is brought about; what in fig. 1 of P1. II. Is placed on the right hand side of the invagination is the capitulum, what is placed on the left hand side the peduncle. As the invagination of the dorsal wall does not reach' as far as the ventral side, a direct communication remains between the capitulum and the peduncle. Through this commissure, which is very narrow in the full-grown animal, pass the oviducts and the nerves destined for the peduncle.

Challenger During the Years 1873-76, Under the Command of Captain George S. Nares, R. N., F. R. S. And the Late Captain Frank Tourle Thomson, R. N, Vol. 24: Zoology; Text The Crustacea Macrura brought home by the Challenger Expedition were placed in my hands for examination and description by the late Sir C. Wyville Thomson, and the progress of the work has gone on under Mr. John Murray, the present Director of the Challenger Publications. The specimens, which were obtained by the dredge, trawl, tow-nets, or by other means, number about 2000, and, arranged according to species and localities, are preserved in about 400 bottles. All these have been carefully examined, the relative numbers of the sexes in most cases determined, and the anatomy and struc ture of one or more specimens of each species studied and figured, except where the specimens were too few to allow of their being broken up and dissected. In making both the descriptions and drawings I have always felt that I was dealing with specimens of more than ordinary interest, since they were in many instances obtained from localities which are not likely to be again explored for some time, and which are scattered over a vast area of the Atlantic, Pacific, and Indian Oceans. Here I wish to express my indebtedness both to Mr. T. Wemyss Fulton, m.e., of the Challenger Editorial Staff, and to Mr. J. C. Richards, the former for his aid in watching the Report through the press, and the latter for his careful rendering of my drawings on the stone.
