 sparsely gi-anular all over, the granules being smaller and closer set in the hinder part, and naked, 

 the forepart of the carapace divided upi by wide, smooth grooves ; the front bent strongly down- 

 wards, with an almost straight, thickened, granular edge and a rather shallow notch in the middle ; 

 the notches in the orbital rim indistinct ; four low side-teeth with thickened, granular edges ; 

 the hind edge of the carapace slightly hollowed ; a feeble ridge on the endostome reaching the 

 fore edge of the mouth ; the basal joint of the antenna short ; the chelipeds unequal, granular 

 all over except on the facet against the body, the hands with a crest and a smooth furrow above, 

 the fingers deeply hoofed at the tip, a little granular at the base, furrowed on the smaller hand 

 only, with a few blunt teeth on the larger hand ; and the walking legs finely granular, their 

 last two joints hairy; the carpopodite and propodite with a crest and a broad smooth groove above."
