granules, each of which gives origin to a seta : the upper border of the wrist 

 forms a high 4- or 5-toothed crest, and the same border of the dactylus is 

 serrated. 



The 2nd and 3rd legs slightly surpass the larger cheliped : their dactyli, 

 though they look much shorter, are really not much shorter than the pro- 

 podites : the only armature is a spine at the far end of the anterior border 

 of the carpus. These legs are sparsely setose, but on the posterior border 

 of the dactylus and of the distal end of the carpus of the 3rd pair there are 

 some tufts — not very thick set — of bristles. 



Colours in spirit : the most constant colouring is that of the dactylus 

 of the 2nd and 3rd legs, which is dark purple at base and ends in a black 

 claw: in some specimens the chelipeds — hand excepted — and the carpus 

 of the 2nd and 3rd legs are olive green, and the other long joints — dactylus 

 excepted — of the legs are light red.

This species agrees in all respects, except the following, with C. terro'- 

 ve^ince, and possibly the latter is merely a variety of C. latens. 



In the large left cheliped the upper and distal borders of the wrist are 

 serrate ; the outer surface of the wrist carries, besides the conspicuous 

 tubercle, numerous scattered denticles ; the upper border of the palm and 

 dactvlus is serrulate, and the lower border of the palm is carinate and serrate. 



As in C. terra-reginff the most persistent colour-mark is that of the 

 dactylus of the 2nd and 3rd legs, the base of which is dark purplish brown.
