Pseudorostral lobes short, upturned. Carapace rounded oval, rather longer than broad, the carinate margin fringed with pellucid scales, ocular lobe small, triangular, frontal lobe broad, medio-dorsal line arched, finely serrate to beyond the middle of the carapace, which in its hinder part has a submedian pair of carinae rising into thin round-topped processes. Pedi- gerous segments combined equal about half the length of the carapace, the first shorter and much narrower than the second, the second and third depressed and spread out at the sides, though still much narrower than the carapace, the fifth not wider than the pleon, which is much longer than the preceding part of the body. Telson much longer than the preceding segment, shorter than the peduncle of the uropods. with anal opening near the base, thence narrowing to the truncate 3-spined apex: 3 pairs of spines are spaced on the margins of the hinder half, the largest pair being subapical. Antenna 1, peduncle rather longer than the flagella. its P* joint more than twice as long as the 2"*^, 3 joint longest of these in the first pair but very short in the second: third and 4*^ pairs alike in 6 and 9, except for minuteness of exopods in the 9. Fifth peraeopods pellucid, vestigial, but the 2"*^ joint, as in the 2 preceding pairs, longer than the following joints combined. Peduncle of uropods a little longer than the endopod. the 3 joints of which have on the medial margin 8 or 9, 3 or 4, and 2 spines respectively: the exopod is a little longer than the telson. which equals the first 2 joints of the endopod.
