Carapace much higher or thicker in front, especially at the bend, than posteriorly. Sternum smooth, concave at middle; genital openings of female lunate, near together on sternum. Eyes small on thick, short stalks; orbits looldng forward. Pedicels of antennules large, longer than ej'estalks, rather stout, near together, spinulous distally, with about three longer terminal spinules; remain- ing articles small, folding vertically, tips reaching but little beyond eyes. Antennae small, nbout as long as eyestalks. Outer maxilhpeds with merus short and broad, with a decided notch on inner distal edge at articulation of palp; ischium broader than long, with a rounded or semicircular lobe on inner margin; exognath small and short; the large palps occupy about all the space to bases of antennules. The anterior lobe of sternum separates the bases of the maxiHipeds. Legs and maxillipeds very hairy. Chelipeds small, smaller than first ambulatory legs; hairy; chelae small, with simple, acute digits. Ambulatories short, incurved, with.

After Verrill. simple, sharp, incurved claws; posterior legs becoming shorter, but similar to the others, articulated slightly higher up. Abdomen convex, the rings thin, somewhat indurated above; in the female the edges are expanded and form a well developed egg-pouch below. (Verrill.) Color.—As follows: Station 28-31. Sepia (with sage greenish tinge when seen through hand lens). Nearly black in fore half of carapace, fighter behind with a narrow median streak. Chelae and carpi almost sage green above; fingers whitish to transparent; ischium and basis of ambula- tories whitish, merus fike carapace, succeeding article wliitish with few marks of carapace color.
