the length of the fingers ; in the female it is rather more than 2*5 

 times as long as wide, in the male nearly 3 times. The fingers have 

 acute inturned tips. The dactylus (text-fig. 101c) is longitudinally 

 carinate in the distal two- thirds of its lower surface, much as in 

 C. superba, but the outer margin is slightly concave and shows no 

 trace of the abrupt angulation found in that species. At its base 

 the dactylus is narrower than the fixed finger. On its inner 

 margin it bears two rather short teeth, the anterior situated a 

 little behind the middle of its length. When the claw is closed 

 these teeth fit between three on the fixed finger ; the foremost of 

 the latter is placed a little in advance of the middle. 



The last three peraeopods (text-fig. loid) are stout. The 

 merus is from 2*75 to rather more than 3 times as long as wide. 

 The propodi are strongly curved and the dactyli are provided 

 with a large hoof-shaped basal process and a very slender and 

 strongly curved terminal spine. 



The telson is slender with the usual six apical spines. The 

 anterior pair of dorsal spinules, as in the preceding species, is 

 placed in the middle of the telson-length with the posterior pair 

 rather nearer to it than to the apex. 



The female, which is ovigerous, is 10*5 mm. in length, the male 

 6-5 mm. 



C. vemtsta is allied to C. super ba, but differs in the smaller 

 number of rostral teeth, in the form of the third maxilliped, in 

 the absence of spines at the distal end of the upper border of the 

 merus of the second leg and in the different form of the fingers 

 in the same appendage. Nobili's C. earner ani ' from Flamenco I. 

 in the G. of Panama is perhaps also related, but differs in having 

 no tooth at the distal end of the lower border of the merus of 

 the second leg and only a single toolh on the inner margin of the 

 fixed finger.
