Mast Head Island: a good series taken on the outer reef, and 

 dredged in 17 fathoms.

Mast Head Island; three specimens, of which one is a male, 

 and two are females. 



Our specimens, which are readily separable from the young of 

 C. niger, agree fairly well with Dana's figure and with Alcock's 

 remarks. In our examples, however, the carapace is sparingly
