obtuse, concave on the upper side, with the subterminal spine visible 

 from above. Antero-external process of the basal anteunal joint short and 

 stout, not reaching the middle of the fourth joint of the peduncle, and 

 double pointed; acicle rounded, pubescent on the inner side, and not 

 reaching the middle of the last joint of the peduncle. Chelipeds very 

 unequal; merus of the larger one trigonal, with the angles rounded and 

 the surfaces convex and marked with small, transverse, granulated, pubes- 

 cent rugae; carpus oblong, distally widened, the sides rounded and the 

 upper surface very convex; surface covered with pubescent, granulated 

 rugae similar to those on the merus, which become broken up, in many 

 places, into separate granules; hand oblong, nearly twice as long as wide, 

 the upper surface evenly convex and granulated; fingers short and stout, 

 the dactyl with a row of granules on the upper side parallel to the outer 

 edge. Smaller cheliped with the merus and carpus compressed and gran- 

 ulo-scabrous; hand small, narrow, with the sides rounded and having no 

 prominent angles; palm more or less inflated, with often a trace of a 

 groove near the proximal end of the upper surface; surface of the hand 

 granulated; fingers pubescent with corneous edges. Ambulatory legs 

 granulo-scabrous, but not spinous, except on the lower side of the dactyls 

 and the distal end of the propodi; dactyls nearly straight, almost as long 

 as the propodi, and not twisted.

Closely allied to hirsutiusculus. Body and legs quite strongly pubes- 

 cent. Anterior portion of the carapace considerably longer than wide. 

 Median tooth of the front quite prominent and sharp; lateral teeth repre- 

 sented only by a slight convexity in the margin. Ocular peduncles mod- 

 erately stout, somewhat constricted in the middle, and about one-half as 

 long as the anterior portion of the carapace. Ocular scales subovate and 

 dorsally concave, with the subterminal spine visible from above. Anten- 

 nal peduncle exceeding the eyes by fully one-half the length of the last 

 joint; acicle rounded above, pubescent on the inner margin, not reaching 

 the middle of the last joint of the peduncle, but nearly reaching the tip of
