This is easily recognized by the very spinose character of the 

 marginal teeth of the carapace and the spiniform tubercles of the 

 chelipeds. The dactylus and thumb are black ; the distal part of 

 the manus liirht red.

This species is apparently very rare at the Bermudas. It is not 

 contained in any of the recent collections examined, nor was it in 

 the early collections of Jones and Goode. One adult siDCcimen was 

 taken by our party in 1898. 



It ranges from Florida to Antilles. Florida (Stimpson). Baha- 

 mas (S. I. Smitli, coll. Bryant). Guadeloupe (Stimpson). Dominica
