nearly straight or directed slightly out- 

 ward. Antero-lateral margins very ob- 

 lique, \vith two large acute teeth, tho 

 first one remote from orbital tooth ; both 

 have straight or concave anterior and 

 convex posterior margins; a rudimentary 

 third tooth. Ilidge above posterior mar- 

 gin made of linear tubercles sometimes 

 confluent. Outer suborbital lobe trans- 

 verse, subtruncate, or a little arcuate; 

 inner lobe more advanced, subtruncate, 

 outer corner rounded, inner lobe with a 

 small vertical tooth; pterygostomian 

 lobe about half as wide and subtri- 

 angular. 



Eight cheliped of male very deep, 

 between two-fifths and one-third as deep 

 as carapace is long. 



Merus of ambulatory legs armed with 

 a large, acute, projecting tooth at an- 

 terior distal angle; granules of upper 

 surface small, depressed; lobes of carpus 

 prominent; propodus broad, not increas- 

 ing much distally; posterior margin of 

 dactylus strongly sinuous. 



Color. Yellowish-rose in alcohol. 



Measurements. Male type, greatest 

 length of carapace 13, width of same 

 14 mm. 



Range. From Charlotte Harbor, 

 Florida, to Barbados. 15 to 7G fathoms. 



Material examined. See table. 



Affinity. Near C. olesa, but carapace 

 less convex, its tubercles very distinct 

 from the elevations which bear them; 

 the two divisions of each frontal lobe 

 more developed and more deeply sepa- 

 rated; outer angle of preorbital lobe 

 dentiform; lateral teeth larger and more 

 hooked forward; ridge above posterior 

 margin formed of linear instead of 

 swollen tubercles; merus and carpus of 

 ambulatory legs shorter and broader, 

 lobes of carpus better developed.
