The body is entirely smooth and naked. The gastric 

 and hepatic regions are scarcely marked ; the dorsal 

 surface is almost flat from side to side, and slightly 

 prominent before and behind. The front is formed of two 

 truncate lobes, finely granular, separated in the median 

 line by a small notch. The internal orbital angles are 

 less projecting than the front. The antero-latcral edges 

 are fine. The postorbital angle constitutes a small lobe 

 scarcely projecting, behind which exists two teeth ; the 

 first is lobiform and rounded, the second is large and 

 obtuse. The orbits are very feebly notched above and 

 below. The basal joint of the external antenn^ii is thin, 

 and joins the front at its antero-internal angle. The first 

 pair of legs of the male short and unequal ; the fourth 

 joint is hid under the carapace ; the fifth is armed on the 

 inside with two teeth. The hand is rounded, and the 

 movable finger has, at its base, a large round tooth. The 

 walking legs are feeble, and slightly hairy towards their 

 extremity. 



The sternal plastron and abdomen of the male are 

 covered with a short down and are slightly toothed. 



Range. — Grenada ; at moderate depths.
