The antennae are rather rudimentary; with the basal peduncular 

 article small, situated at the outer angle of the antennular f ossett ; the 

 second and third articles very short; the flagellum multiarticulate, 

 very slender; when extended, scarcely reaching to the base of the 

 cornea. 



The external maxillipeds are rectangular, close-fitting, the merus is 

 moderately indented on the external surface and its inner distal angle 

 obliquely truncated for the attachment of the stocky palp and the 

 outer distal margin a little oblique. Just above the merus are the two 

 rounded apertures of the excurrent channel, one in each outer angle of 

 the epistome. 



The chelipeds are distinctly unequal in the male ; the merus not ex- 

 tending beyond the carapace with the upper inner lateral margin 

 spinose; the carpus is rounded, coarse, granulose and beset with nu- 

 merous solitary setae ; these granules become spinose toward the distal 

 end and there is a strong spine at the inner carpal angle. The palm 

 of the larger chelipeds is dilated, with its height equal to two-thirds of 

 its length; the outer and upper surface convex and covered with 

 coarse, conical granules, which become abruptly smaller on the imme- 

 diate lower margin and are present in less degree on the inner surface 

 of the palm ; there is one larger node at the upper proximal margin ; 

 the fingers are sharply deflected, black, faintly grooved, the upper 

 finger of the larger cheliped with a coarse basal molar; the cutting 

 edges of both fingers meeting; the tips are sharp. The smaller cheli- 

 ped is like the larger except that it is little more than half so high. 



The ambulatories are all slender, beset with solitary bristles; the 

 merus, carpus and propodus are laterally compressed, subcylindrical, 

 the dactyl is very slender, long, acuminate, longitudinally grooved and 

 with two lines of short brown fur in addition to the longer bristles.
