The surface of the carapace and chelipeds is polished and shining, with no indications of hair* or granulus. The chelipeds of the adult males art' relatively large and st nmg, subequal, with the claws gaping.

In the voung these teeth are Figure 42. — side, about nat. size. adult male from Bermuda, under Phot. A. H. Verrill. The carpus and chela1 are smooth, with no tubercles except a small denticle on the inside edge of the carpus ; the merits bears two large acute spines on the inner margin, and about 4 or 5 much smaller, obtuse ones on the outer margin ; the upper surface may have a few minute ones, or in adults a row of two or three obtuse ones. The ambulatory legs are rough with small short spines and long unequal stiff hairs; the dactyls are strong, incurved, with sharp tips; there is a prominent articular plate at the superior distal end of the propodus. The basal antenna! plate is wide and thick, tridentate; the outer tooth, which is much the largest, is broad and obtuse, its base occupying about half the width of the plate; the next is not more than half as large and subacute; it is separated from the still smaller.
