Antero-lateral margin with a coarsely granulate or creniilate edge, 

 <iut into 9 teeth or lobes which are shallower than in plehejus, each 

 tooth having a slightly projecting point; first tooth broadest, com- 

 posed of the small, triangular outer tooth of the orbit joined to a 

 truncate strip of the anterior margin; 2 postero-lateral teeth, the outer 

 one better defined. Teeth of front broadly triangular, the blunt 

 median tooth only slightly depressed and overreaching the adjacent 

 pair but little ; the teeth of this pair directed obliquely outward. Inner 

 orbital tooth subacute, tooth of basal antennal article narrower and 

 more produced, and followed by a small tooth on the suborbital mar- 

 gin. The outer maxillipeds fit into the buccal cavity, the extremity 

 of the merus is obliquely placed. Merus of cheliped widening con- 

 siderably to the distal eud, 2 small sharp spines above; carpus with the 

 customary short pyramidal tooth at inner angle; 4 outer granulated 

 -carinae on palm separated by a shallow depression from the pair of 

 superior carinae which are near together and rough with acute 

 granules; dactyl sharply granulate, non-carinate. Dark color of 

 fingers extending the whole length of the prehensile edge and but a 

 short distance from the tip along the outer edge. Chelae much 

 smoother in the old, carinae faint. Legs long and narrow.
