Description. — Similar to C. irroratus. Antero-lateral margins more 

 broadly rounded; surface much rougher with coarse uneven granules; 

 carapace higher, the convexity ending rather steeply at the dentate- 

 rim; lateral teeth with denticulate edges; behind the two postero- 

 lateral teeth there are in old specimens one or two more smaller 

 teeth indicated by slight notches. Chelipeds heavier and rougher; 

 hand liigh, 7 coarsely granulate carinae on outer-upper surface, the 

 uppermost one denticulate; movable finger vnth a very rough upper 

 margin; ambulatory legs correspondingly rough. Side margins of 

 5th-6th abdominal segments in male more nearly parallel than in 

 irroratus. 



Color. — Brick red above, yellowish beneath, the limbs corresponding 

 more or less in coloration with the lower surface, but of a light red- 

 dish tint above. 



Measurements. — Male (2134), length of carapace 97.8, width of 

 same 154, fronto-orbital width 36, width of front between antennae 

 13.6 mm.
