„Form compact, sublinear in shape. Carapace little wider than the pleon, 

 emarginate posteriorly, evenly rounded in front. Pleon longer than the carapace, 

 with the first five segments subequal in length, the last segment once and a half 

 to once and two-thirds as long as the fifth. Ocular lamina sligthly cleft in the 

 middle line, composed of two sub-rectangular contiguous plates; extending to 

 barely the distal ends of the basal joints of the antennules, each plate exhibiting

near the mid-dorsal line a rather prominent corner, which is much more pronoun- 

 ced in the male than in the female; plates hispid, armed on the anterolateral 

 margins with about fifteen teeth, lateral margins smooth. Antennular peduncle in 

 the female moderately slender, basal Joint the longest, nearly as long as the other 

 two combined; second Joint small, whole peduncle feebly setose; in the male 

 much stronger and longer, distal Joint nearly as long as the basal, male appen- 

 dage well developed and very hirsute. Antennal peduncle slender, in the female 

 shorter than the antennular peduncle, last two joints subequal; in the male longer 

 and more slender than in the female, as long as the antennular peduncle, the last 

 Joint somewhat longer than the second. Antennal scale comparatively short and 

 narrow, in the female extending for only a little way, in the male not extending 

 beyond the antennular peduncle, about four times as long as broad, outer margin
