is not at all oblong; and the same is true of the last segment, which is 

 obtuse.

Near C. sanguineua. Carapax not shining, anteriorly areolate, poste- 

 riorly smooth, sulci not deep, areolets 2 K, 3 R not separated, antero- 

 lateral margin neatly 5-toothed. Hand and carpus stout, smooth 

 and even. Eight posterior feet compressed, unarmed, pubescent.

 of outer maxilliped.

Length of carapax, five lines; greatest breadth, seven and one- 

 fourth lines; ratio of length to breadth, 1 : 145. 



Differs from the sanguineus in having but five marginal teeth, there 

 being none posterior to S, and no inferior tooth between D and E, 

 which characterizes that species ; also, unlike the exaratus, the carpus 

 and hand are not uneven in the upper surface, and the teeth are 

 thin and even. In the male, the areolets are rather faint, and 4 L 

 and 5 L are coalesced, and of about equal width ; in a female, 4 L and 

 5 L are faintly separated, and the latter is the broader, as in the san- 

 guineus.
