Description. — Cephalothorax moderately short. Ophthalmo- 

 pod short, depression in which it rests small, eye moderate, and 

 peduncle nearly as robust as latter, though at base sm^aller. First 

 antennae biramous, outer branch shorter. Second antennse long- 

 as rest of body, multiarticulate, with broad long flagellum nearly 

 equal to first antennse in length. Rostrum short simple point, 

 extends forward about midway between exposed ophthalmopods. 

 Mandibles slender, curving in rather spacious mmith, ends tri- 

 dentate. Labia well developed, upper of three elements of about 

 equal proportions of which median rather evenly convex in 

 shape, and lower broad, thin, deeply cleft medianly with each 

 lobe well extended laterally. First maxillae short, like mandibles. 

 Second maxillse with rather long slender basis, thus much longer 

 than first maxillae. Pereion rather cylindrical, short. First 

 maxilliped long, compressed moderately at basal region, non- 

 chelate, and with exopodite little longer than that of second 

 maxillae. All exopodites, on first and second maxillae and on 

 first raaxillipeds, more or less subequally long, flagellate, and 

 their distal filaments quite acuminate. First peraeopods enlarged, 

 stout, partly chelate, merus shorter and broader than basis, and 

 dactylus depressible against oblique trenchant edge with short 

 sharp erect spine at pollux. Second peraeopods, also third, 

 fourth and fifth, slender, subequally long, with articulations of 

 more or less even proportions, and dactyli all slenderly acumi- 

 nate, not chelate. Pleon capable of being evenly curved, with 

 third shield largest, though sixth much longer and also narrowly 

 compressed. Five pairs of pleopods ending acuminately, and 

 shorter similar interior podite to each. Telson sharp slender 

 acuminate finn process, with external elements of rhijjidura each
