wider, at the apex, than long and the thh'd article is one-fourth longer than the second; 

 the stylocerite extends to the distal fifth part of the second article. 



Basicerite unarmed above, lateral spine a little shorter than the stylocerite and reaching 

 to the middle of second antennular article; carpocerite 3-times as long as wide, in the typical 

 species 4-times (H. Coutiere, in: Bull. Soc. Philom. Paris, Ser. IX, T. XI, 1908, p. 5) and 

 surpassing the antennular peduncle by about two-thirds the third article; scale rather broad, as 

 in Fig. 7 (1. c. 1905), its width being one-fifth the total length of the scaphocerite, the scale 

 just as long as the antennular peduncle, terminal spine a little shorter than the carpocerite. 

 The female has lost both chelipeds, the male possesses only the small one. In this cheliped 

 the merus is 2^l.^-tlme:S as long as wide, the upper margin bears a small, acute tooth at the 

 apex; the relative dimensions of the chela are; fingers i; total length 2,66; height 0,94, the 

 chela being 2,85-times as long as high. 



The second legs of the male resemble those of the typical species. Merus 5,84-times 

 as long as thick. First segment (1,25 mm.) of the carpus 5, 3-times as long as thick distally 

 and slightly longer than the sum (1,16 mm.) of the following; fifth segment as long as the 

 second and the third together, the third slightly longer than the second; chela (1 mm.) twice 

 as loner as the fifth segment.

Relative dimensions of the third legs in the male: merus 2,1; carpus i; propodus i,S. 

 Merus 3,8-times, propodus 6-times as long as wide, the latter with 6 spinules long 0,14 — 0,16 mm. 

 According to Coutiere's description (1. c. 1905) the merus should be 4,5-times, the propodus 

 8-times as long as wide and the propodus should be armed with 5 or 6 spinules ; in another 

 paper, however, in: Bull. Soc. Philom. Paris, 1908, p. 5 the merus is described as being 4-times 

 as long as wide and the propodus with 8 spinules. The length of the dactylus, measured from 

 the proximal extremity of the anterior margin to the extremity of the ventral hook, appears to 

 be one-fourth the length of the propodus and 2, 4-times as long as the dactylus is wide near 

 the articulation ; the dactylus accords with Fig. yd" of the original description, the dorsal hook 

 appears a little more than half as thick, but decidedly longer than the other and one observes 

 a slight, obtuse prominence on the posterior margin. The anterior margin of these legs is a 

 little setose. 



The relative dimensions of the fourth legs are in the female: merus 1,8; carpus i; 

 propodus 1,8. Merus 3,7-times, propodus 6-times as long as wide, the latter with 5 spinules 

 long 0,15 mm. Dactylus as in the third pair. 



Ova small, 0,6 mm. long. 



The ova-bearing female is 16 mm. long, the other specimen is a little shorter.
