Carapace longer than wide, ovately trigonal, surface smooth, as if denuded, with scat- 
tered tufts of brown, villose hairs, and finely granulose towards the hinder part ; a small, 
slightly prominent tubercular spine in the centre of the ventricular prominence ; a small 
prominent spine in the middle of each lateral or branchial region, situated towards the 
posterior part, and three small tubercles arranged above this, in a linear series, extending 
towards the fore part of the carapace ; lateral margins entire, posteriorly, with three obtuse, 
slightly prominent spines towards the anterior part, at which situation the carapace becomes 
suddenly contracted. 
Front with two strong, prominent, rather short, parallel spines, somewhat incurved 
towards their apices, and covered with thick, strong, curved hairs. Orbit, anteriorly, entire, 
deeply incised posteriorly, with a prominent, obtuse, angular tubercle behind the notch. 
Fore-legs smooth, small, slender, equal in size, covered with scattered, long, stout hairs ; 
the third joint subeylindrical, curved inwards and enlarged anteriorly ; fom’th joint short, 
rounded, and curved with two small tubercles on the outer and upper surface ; fifth joint
