The carapace from the apex of. the serrate rostrum is 18'5 mm. 

 long in the median line, with a breadth of about 10 mm. The 

 sternum between the first three pairs of legs is nowhere linear, 

 increasing in width behind the bases of the chelipeds and 

 then narrowing to a pair of nodules between the basis of the 

 second peraeopods, whence it again widens almost to the interval 

 between the third pair. On the thumb of the chelipeds in our 

 specimen the inner margin has only four denticles, whereas in 

 Henderson's smaller example there were five. The last pair of 

 limbs are small, but not filiform, the terminal joint oval, its 

 distal extremity the broader.
