nearly straight or directed slightly out-

 convex posterior margins; a rudimentary 

 third tooth. Ividge above posterior mar- 

 gin made of linear tubercles sometimes 

 confluent. Outer suborbital lobe trans- 

 verse, subtruncatc, 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. 



I^ight chelipcd 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.

Ajjinity. — Near C. ohcsa, but carapace 

 less convex, its tubercles very distinct

 the two divisions of each frontal lobe 

 more developed and more deeply sepa- 

 rated ; outer angle of preorbital lobe
