This little species agrees in every particular with C. cequabilis (var. 



vterguiensis), except that the eyestalks are much shorter, being not so long 



as the anterior border of the carapace, and considerably shorter than the 



antennular peduncles.

 Tr. Linn. Soc, Zool., (2) V., 1893. p. 424. 



This species, besides being much larger and differently coloured, differs 

 from C, cequabilis (var. merguiensis) in the following particulars : — 



There are numerous tufts of setae on the gastric region, and in a trans- 

 verse series behind the cervical groove. 



The eyestalks are shorter than the antennular peduncles ; and the 

 ophthalmic scales are narrow and pointed, and bifid at tip. 



The antennal acicle and the basal joints of the peduncle are more setose. 



There are fewer conical spinules on the hand and wrist ; indeed the only 

 conspicuous spine on the wrist is one at the far end of the inner border- 



The dactylus of the and pair of legs is about five-sixths the length of 

 its propodite, and that of the 3rd pair is exactly as long as its propodite. 



Though the propodite of the 3rd left leg has its outer surface flattened 

 and the upper border of that surface is well defined, it is not subcarinate. 



Colours in spirit : carapace yellow ; eyestalks, antennal peduncles, cheli- 

 peds and legs deep orange-red (finger-tips and claws of dactyli black). 



Length of carapace 30 millim.
