Carapace broad, branchial regions inflated, upper surface naked, smooth, 

 and polished ; the branchio-cardiac lines meet in the median line of the 

 carapace ; the anterior margin has a concavity above the eye, forming an 

 orbit with a spinule at its external angle. There is one spine at the antero- 

 lateral angle of the carapace, and ten or eleve'^ on the lateral margin ; 

 the lateral spines decrease in size posteriorly. The rostrum is long, taper- 

 ing, acute at the apex, and concave at the base above. The abdomen 

 is smooth, the pleuroe subacute. The eye-stalks are short and stout, the 

 eye not wider than the peduncle, black. The antennae are very slender, 

 shorter than the carapace, the acicle considerably shorter than the peduncle. 

 Chelipeds very long, naked except for a few setse on the fingers, polished ; 

 the ischium bears a spine on the superior margin and several others on the
