256 PERCY SLADEN TRUST EXPEDITION 



The immature males, as well as the females, have a more flexed rostrum than the 

 adult males. The protuberances on the outer and lower margins of the arm, and some of 

 those on the outer surface of the wrist, are short, stout spines.

 pi. 1, figs. 2 — 2 c. 



Coetivy ; 1 $. 



Surface, except ends of fingers, covered with coarse tubular setae, mixed with longer 

 curved hairs of which there are many fine ones on the carapace, especially near the lateral 

 margins, and very coarse ones on the margins of front, antennae and legs. Carapace sub- 

 triangular, with the lateral angles more rounded than shown in Edwards' figure 2 (op. cit.), 

 regions well delimited except the hepatic ; a small areolet is situated on the inner side of 

 the branchial region contiguous to the posterior half of the cardiac region. Front less 

 deflexed than in Edwards' figure 2 c. Rostral horns about -J length of remainder of 

 carapace, upturned near the extremity, tips incurved. Basal joint of antenna no broader 

 than long, most advanced at inner angle, unarmed ; remainder of antenna visible beside 

 rostrum ; first movable joint twice as long as second, together they exceed the flagellum. 

 Postocular lobe set oft' by a deep gap, above and below ; supraocular eave entire. The 

 orbit is much less tubular than in Macrocceloma. 



Chelipeds equal to median length of carapace, stoutish, palms inflated, narrowed 

 distally, 1^ times as long as fingers, which have denticulated edges and gape in their basal 

 half. The fringes of curled hair on the legs make them appear stouter and more prismatic 

 than they really are ; the first pair reaches beyond the cheliped by the length of the 

 dactylus. 



There are two or three tubercles on the pterygostome. The merus of the outer 

 maxillipeds is not so strongly produced outward as in Edwards' fig. 2 b (op. cit.). The 

 seven segments of the male abdomen are distinct.

In most of these specimens, none of which exceeds 17 mm. in length, there is an 

 acute granule on the posterior margin of the carapace between the outer and the median 

 pair of tubercles.
