In our specimen of this species the infra- or post-orbital 

 crest is 2- or 3-lobate externally, and crennlated internally. 

 There is an obsolete emargination on the lateral margin of the 

 carapax at its anterior third. The surface toward the front and 

 antero-lateral margins is minutely rugate or granulated. The 

 male abdomen narrows toward its extremity as in C. punctatus^ 

 Whether these characters accord with those of the true C. in- 

 teger^ the meagre descriptions as yet published do not enable- 

 me to determine. 



Found on the coast of Florida.
