Description.—Carapace considerably broader than long, sides with tAvo teetli behind the orbital tooth. Surface finely punctate and pu- bescent. Eegions little marked; a gastro-cardiac sulcus; a depression at the inner angle of the hepatic region; a sulcus between the epigastric Icbes. Lower edge of front sinuous as seen from above, being arched over the antennules; convex in front view; outer angles rounded; sides oblique. Upper margin of orbit sloping backward and outward. The orbital and two side teeth are sharp pointed, deeply separated, and diminish in size from the first to the last; the first and second are similar, their outer margin convex; the last is slender, outer margin straight. Epistome very narrow, and in front view concave each side of the middle. Inner half of postorbital stridu- lating ridge in male very finely striated; outer half formed of two elongated tuber- cles, the inner of which is twice as long as the outer, and is continuous with the striated portion; in the female there are four elongated dentiform tubercles and at the inner end a few denticles. Outer surface of arm crossed by short squamiform rows of fine granules; a very prominent lobe on the distal half of the inner margin bears a horny ridge. Inner angle of wrist produced in a very small tooth in the male, a spine in the female. Palms of male swollen, smooth, above proximally marginate; fingers stout, with fine prehensile teeth and a linear gape; a large patch of long hair occu- pies the center of the inner surface of the chela. The chela of the female is very small, upper margin of propodus complete, a ridge on lower part of outer surface; fingers faintly grooved, more broadly spooned than in male; inner surface of palm with a few hairs. Legs slender, hairy, carpal and propodal joints, save in the last pair, densely pilose; merus joints crossed by short, granulated lines; dactyli s
