Dorsal profile of peraeon segments 6 and 7 and pleon segments 1-4. b, c, d. 2nd (and 3rd) joints of peraeopods 3-5. Description. Like puncticulata, Brnrd., but peraeon segments 5 and 6 slightly keeled and ending posteriorly in a short point. Peraeon segment 7 and pleon segments 1-3 strongly keeled, the keels beginning near bases of segments, slightly indented in middle of dorsal profile, and ending in prominent subacute apices. Pleon segment 4 with sharp-pointed upstanding triangular process. A series of dorso-lateral tubercular processes on peraeon segment 7 to pleon segment 3, faint on peraeon segment 7 (some- times also one on segment 6) and on pleon segments 2 and 3, consisting of a short ridge or keel near base of segment and a conical tubercle on hind margin. Peraeopods 3 and 4, 2nd joint with the point of divergence of the outer and inner keels distal to the rounded basal lobe, inner keel not expanded, lateral longitudinal keel confluent in distal third with the outer keel and forming the subacute apex of the di
