Body long, nearly cyliudric, smooth; pleon segment 4 produced latero- 

 dorsally into 2 microscopic teeth. Head long, front truucate. Side-plates sub- 

 quadrate. Pleon segment 3, postero-lateral corners quadrate. Eyes represented 

 by 2 patches of whitish pigment. Antenna 1 nearly as long as body, 1^* Joint of 

 peduncle about half as long as 2^ or 3"^, flagellum rather shorter than 2*^ and 

 3*^ combined, about 12-jointod; accessory flagellum 4- or 5-jointed. Antenna 2 

 rather shorter, ultimate and penultimate joints of peduncle subequal; flagellum 

 more than half as long as peduncle, 9-jointed. Guathopods 1 and 2 setose. 

 Gnathopod 1 in d, 5*^ Joint longer and wider than the oval, distally narrowed 

 6*^; palm oblique, deliued by a palmar spine, slightly overlapped by the 

 fiuger. Gnathopod 2 in d, 5^*^ Joint as long as 6^^, which is widest where 

 the straight, very oblique palm is defined by a strong tooth. Gnathopod 1 

 in 9 more slender than in d, but similar. Gnathopod 2 in 9 like gnatho- 

 pod 1, but rather stouter; marsupial plates long and narrow. Peraeopods 1 

 and 2 nearly twice as long as the gnathopods; peraeopods 3 — 5 still longer. 

 Uropod 1 longer than uropod 2, the rami slender in both, outer rather the 

 shorter. Uropod 3, the small Single Joint scarcely reaching end of the obtusely 

 pointed telson. Colour greyish white, transversely banded with faint orauge»
