Integument thin, brittle, squamose. 

 Pseudorostral lobes produced to about 

 one-fifth of the length of the carapace: 

 antero-lateral corners obsolete. Ocular 

 lobe forming a narrow equi-lateral triangle, 

 Avithout visual elements. Carapace about 

 as long as the pleon without its telson, 

 wrinkled by numerous denticulate swel- 

 lings, chiefly transverse but in part con- 

 nected by others at angles with them.

 Pleon segments 1 — 5 with 3 longitudinal 

 denticulate swellings. Antenna 2, P* joint 

 nearly spherical, with plumose seta on a 

 conical process, 4*^ nearly as long as 

 preceding 3 joints combined. Peraeopod 

 1 slender, rather long, b^^ joint slightly 

 longer than 6*^. Peduncle of uropods 

 very slender, subequal to pleon segments 

 4 — 6 combined. Colour white. L. 9 at least 13 mm. d unknown
