MALE. The only specimen found (pi. TIT, fig. 1 a — 1 h) is 174 mm. long. The 

 body comparatively somewhat shorter and broader than in S. dcganftiJa; the median frontal 

 plate of medium length, a little broader at the end than behind the middle, with rounded 

 anterior angles. Trunk-legs, the fii'st pair particularly, a little shorter and somewhat more 

 slender than in S. eJeganfnJa and a little shoiter than the long terminal seta. 



OVISACS and LARVA. Unknown. 



POST-LARVAL DEVELOPMENT. Two pup* have been found, one of them 

 146 mm. long (fig. (ic), in which no animal had as yet developed itself (fig. 6 e) (the strongly 

 coagulated contents are marked in the drawing by dai-ker shading); the other, -24 mm. in 

 length (fig. 6d, hair-covering omitted) contains an almost fully developed female (fig. 6f). 

 Both pupae, a more detailed mention of wliich is given on p. 58 — GU, are closely covered 

 with haiis all over, except on the area in front of the mouth. 



HABITAT. The marsupium of Corophhim Bonpllii M.-Edw. from Hong-Kong. 

 In one specimen were found : one female, one male and one pupa, in another one pupa. The 

 hosts were taken by H. Koch (1872) and kindly determined for me by the Rev. Th. R. R. 

 Stebbing. 



8. Sphaeronella antillensis n. sp. 



(PI. Ill, fig. 2 a— 2 f.) 



FEMALE. There have only been found very small, recently hatched specimens and 

 a single large one, which was quite torn. We begin by describing the latter. Rather few 

 hairs are seen on the proximal part of the inner side of the basal joint of the maxillae, and 

 a small tuft in front of the foremost inner angle of each maxilliped. The trunk is quite 

 naked. The genital area (fig. 2 d) chitinised and shaped almost as in S. AtyJi, but the 

 anterior and posterior margins are somewhat less concave; the distance and position of the 

 genital apertures as in the lastmentioned species, but the caudal stylets are somewhat closer 

 together and only at a short distance from the posterior margin of the area; the area aud 

 its surroundings naked. — In the tlu-ee young ones, two of which are recently hatched and 

 the third on the point of moulting (fig. 2 c), the hair-tufts on the head are exactly like those 

 of the adult specimen. In the two specimens the tinnk is naked, in the third it is furnished 

 with a number of exceedingly short and fine hairs, wliich occupy a short part behind the 

 head. The genital area is not developed, thus agreeing with the above-described area in a 

 young one of S. danica; between and behind the genital apertures are found a number of 

 very fine hairs. 



MALE. Unknown. 



OVISACS. Of medium size, somewhat elongate (fig. 2b); an ovisac which was 

 measui-ed appeared to be -So mm. in length and -27 mm. in breadth.
