Side-plates 5-7 shallow, anterior lobe of 5 and 6 very small, anterior and posterior corners serrulate and spinulose. Pleon segments 1-5 + 6 carinate, the carina produced to a tooth only on segment 4, which has the usual little notch. Postero-inferior angles of segments 1-3 quadrate, each with an oblique keel running out to the short acute point, lower margin of segment 1 setose, of segments 2 and 3 spinulose, the spinules set in little groups of 2-3 just within the margin. Telson, lobes tapering to subacute apices, each with a spinule in the apical notch. Antenna 1, 2nd joint longer than 1st, 3rd considerably shorter, flagellum 31-32- jointed, peduncle and flagellum with setae on lower margin. Antenna 2 about as long as antenna 1, 4th joint slightly longer than 5th, flagellum about 20-jointed, peduncle and flagellum setose, but not densely.
