On the outer surface of the carpus of the left cheliped there is an 

 irregular row of enlarged granules parallel with the inner border. 



The palm of the hand is as long as high, and the lower portion of its 

 outer (granular) surface forms a flat facet bounded posteriorly by a short ridc^e 

 running parallel with the carpal articulation ; the granules on this rid'^e and 

 at the junction with the lower border of the palm are enlarged. 



The left hand when fully extended has a slight inclination inwards. 



From var. affinis it is distinguished by the form of the hand, the fixed 

 finger of which, also, is straight ; the narrower and slightly longer rostrum 

 and the longer antennal flagellum. 



From var. violaceus it is distinguished by the form of the hand, and by 

 the more setose antennal flagellum.

Cephalothorax broad and very flat. Carapace broader than lon^^; the 

 region in front of the cervical groove contracted, and beset— except for a 

 well-defined smooth patch in the mid-gastric region— with transverse setose 

 serrulated ridges. Behind the cervical groove there are numerous tufts of 

 setae and vesiculous granules. 



Rostral appendage longer than the ophthalmic scales, two-fifths to one- 

 third the length of the eyestalk, its edge spinulose. 



Eyestalks abouc three-fifths the length of the anterior border of the 

 carapace, reaching nearly to the middle of the terminal joint of the anten- 

 nular peduncle, but not much beyond the base of the terminal joint of the 

 antennal peduncle, the antennal being a little longer than the antennular 

 peduncles.
