Wrist two-spined. Buccal cavity widening anteriorly. Legs slender. Third abdominal segment narrower than the sternum. Descrijdion.—Carapace more convex longitudinally than trans- versely; lateral teeth upturned. Front between a third and a fourth of the widtli of the carapace, deflexed, lobes slightly convex, median notch V-shaped. The orbits trend forward and outward, and there is a shallow lobe between the two upper fissures; below tlie blunt outer angle, a large sinus; the feeble inner tooth is situated be- low the middle of the eyestalk which is narrow except at the base and fits snugly in the orbit. Of the five antero-lateral teeth, the second is lobiform and separated from the orbital angle by a shallow sinus; third tooth more or less truncate; fourth and fifth spini- form, subequal; carapace widest at the last tooth. Postero-lateral margins moderately convergent. Arm provided with a strong superior subterminal tooth. Wrist with a deep sulcus parallel to the margin next the palm, and two stout spines at the inner angle, one below the other, the upper one the longer. The palms are convex above and below, and the upper margin is granulate. The fingers are slender, much deflexed and curved inward; the dactyli are granulate above at the proximal end; the fingers are irregularly toothed along their prehensile edges which gape narrowly. The meral and carpal joints of the legs are hairy along the anterior margins, the propodi along both
