Carapace subglobose, encircled about at the middle by a stout sinuous ridge closely set with stout spines, in front of ridge many spines, mostly uncinate and distally tuberculate, and on each side a single smooth straight spine longer than the rest; behind the ridge spines larger, less crowded, short, stout, conical; lower margin fringed with spines at the rear short and thick, towards the front long and slender. Eyelobe and eye wanting. Pedigerous segment 2 at the sides covering the 1 ^S 'M and 4^^' fused, their side- plates not expanded, those of the 5*'! not extended backwards. Pleon segments 1—6 beset with spi- nules. Telson longer than peduncle of uropods, V4*^^ of length cylindric, with sides denticulate near the base, the tapering post-anal fourth slightly decurved, with subapical pair of setules and apical pair of spinules. Antenna 1, first 2 joints of peduncle rather long, accessory flagellum small. Peraeopod 5 arti- culated near the dorsal surface of the segment. Peduncle of uropod about Vg*^^ as long as telson, with 8 spinules on distal half of the medial margin; •endopod not quite half as long as the peduncle, with long slender spines on the medial margin, P* joint longer than 2°^ and 3'^ combined, 2"<i longer than 3*^. exopod only reaching end of the 2'^'^.
