Integument moderately indurated, with numerous minute ridge-like granules causing a granulate appearance; these granules are arranged mostly trans- versely, and are more distinct and prominent on the pleon segments, but extend also over the 2nd joints of peraeopods 3-5.

Telson, with sculpturing indicated. rounded, post-antennal angles quadrate, hidden under 1st side-plates. Eyes large, sub- rotund. Peraeon broadly rounded in anterior portion, the posterior margins of segments 1-4 slightly thickened; segments 5-7 with medio-dorsal keel, which is largest on seg- ment 7, and on all three segments ends posteriorly in a forked tooth; postero-inferior angles of segments 5-7 becoming increasingly prominent and produced; posterior margins of segments 6 and 7 with a lateral tooth between the dorsal one and the postero-inferior angle. Side-plates shallow, 1 and 2 rounded, 3 subquadrate, 4 trape- zoidal, excavate behind, 5 and 6 with the anterior and posterior lobes subequal, 7 oblong. In the $ the lateral tooth on segment 6, the postero-inferior angles of seg- ments 6 and 7 and the posterior angle of side-plate 7 are shortly bifid. Pleon segments 1-3 carinate, carina forming a forked tooth on segments 1 and 2, and a simple to
