Wrist sub- rectangular. Abdomen of male with third to fifth segments fused and not covering the sternum at the third segment. Description.—Carapace very convex fore and aft, regions indis- tinctly defined, surface closely set with flattened granules. Front subtruncate, a V-shaped median notch, a rounded lobe at outer angle. Antero-lateral teeth four (orbital angle excluded); the first small, separated from the orbit by a long, straight interval; second tooth widest; third and fourth most acute, the third the larger; the fourth the most projecting. Chelipeds (the right one at least) strong, covered with fine reticu- lated granulation; merus project- ing little beyond the body, a strong subterminal tooth above; carpus subquadrate, with a consjncuous tooth at inner angle, and the outer- most portion tuberculate; palm nearlj^ twice as long as high, widen- ing distally; dactylus as long as palm; both fingers strongly deflexed, not gaping, tips curved and overlapping. Ambulatory legs long and narrow; meral joints granulate a
