Carapace sub pyriform, nearly as broad as long, convex and tuber- 
culated. The rostrum consists of two vertically compressed spines of 
no great length, which are fused together in half or more of their 
extent. The eyes are short. The commencing orbits are formed by a 
supra-ocular eave and a post-ocular tooth, the interval between this 
tooth and the supra-ocular eave above, and between it and the basal 
antennal joint below, being partly closed in each case by a spine. The 
basal antennal joint is truncate-triangular; its antero-external angle is 
produced, and there is a second spine behind the middle of the outer 
border: the mobile portion of the antenna is visible from above on 
either side of the rostrum. The merus of the external maxillipeds is 
as broad as the ischium. Chelipeds in the adult male considerably 
longer than the carapace and rostrum, and having the palms inflated. 
Chelipeds in the female very slender throughout, and a little longer 
than the carapace and rostrum. Ambulatory legs extremely long and 
slender, the first pair being about six times the length of the carapace 
and rostrum : the dactylus in all is remarkably long. Abdomen of 
male seven-jointed: of female five-jointed.
