Carapace not much depressed, its greatest breadth across the branchial 

 regions about two-thirds its length in the middle line ; hardly setose except 

 on the antero-lateral margins. 



Eyestalks depressed, much broadened distally, about two-thirds the 

 length of the anterior border of the carapace: they reach about two-thirds of the 

 way along the terminal joint of the antennular peduncle and are hardly 

 longer than the antennal peduncle. Eyes broadly reniform, occupying from 

 a half to two-fifths of the length of the eyestalk. 



Antennal acicle serrulate and setose, reaching well beyond the base of 

 the last joint of the antennal peduncle. 



Legs and chelipeds very sparingly setose. Left cheliped vastly larger 

 than the right, its length measured in a straight line (chord) about i| times 

 that of the carapace measured in the middle (sagittal) line : its merus has 

 the lower border alate and strongly and irregularly serrate ; its wrist has 

 the upper and outer surface beset with strong teeth, of which those along 

 the inner border are the largest ; its short and deep hand bears two raised 

 longitudinal rows of tubercles along its upper surface, in addition to a row 

 of sharp teeth along the inner border and numerous interspersed granules, 

 and its lower border is well defined and crenate, but the lower part of its outer 

 surface is smooth : the inner edge of the upper surface of its dactyliis forms an 

 upstanding crenulated crest. 



The crawling-Iegs of both sides are of nearly the same length, and 

 reach beyond the tip of the larger cheliped ; the upper surface of their 

 three terminal joints is broken, or distantly tuberculous, not distinctly 

 spinose. 



The propodite and dactylus of the third left leg are characteristic : they 

 have the outer edge of the upper surface raised into a thin, sharp, finely- 

 crenulated, overhanging crest ; and the outer surface of the dactylus is deeply 

 concave. 



Colours in spirit : biscuit-yellow, often with reddish cross-bands on 

 eyestalks and legs. 



Length of carapace nearly 30 millim, (in a specimen from the " South 

 Seas " 38 millim.) 



Numerous authors have commented on the fact that in this species 

 the males possess orifices corresponding with the openings of the oviducts 

 of the female.
