numerous spines on medial margin; exopod stouter but scarcely longer than 

 endopod. in which the 1^* joint is about three-fourths as long as the more 

 slender 2""^, with 9 and 11 spines on them respectively, each apical spine 

 the longest. Colour greyish, with irregularly distributed red-brown spots.

Pseudorostral lobes rather short, apically truncate; antero-lateral corners 

 acute in 9, rounded off in d. Carapace not very elongate, with low carina, 

 but no teeth in either sex. Pedigerous segment 2 large, laterally acutely 

 produced over lower part of segment 1 on to the carapace. Eyelobe 

 broader than long, prominent in d with 9 corneal lenses of which the middle 

 one is very large. Antenna 1, 3*^ joint nearly as long as 1^*, a little less 

 than twice the 2°^, flagellum 1-jointed, accessory minute, 2-jointed. Maxilli- 

 ped 3, 2"*^ joint apically produced nearly to the end of the 4^^, which only 

 reaches half way along the 5^^ but is fringed with many plumose setae. 

 Peraeopod 1 of moderate length, 2"<i joint as long as rest of limb, 4*^^ and 

 5*^ joints equal, 6^^ and 7*^ successively a little shorter. Peraeopod 2 scarce- 

 ly as long as the 3<^ pair. Peduncle of uropods decidedly longer than 

 the rami, the exopod a little longer than the endopod, of which the 1^* joint is 

 about two-thirds as long as the second and carries 4 graduated spines, among 

 which in the d 4 spinules are distributed; the narrow 2°^ joint in the 9 

 has 1 1 graduated spines and in the d a considerably larger number. Colour 

 red-yellow with brown and chalk-white shadings. L. 9 9 mm, d 8 mm.

Pseudorostral lobes not strongly produced; first pedigerous segment 

 only dorsally distinct; telsonic segment not produced between bases of the 

 uropods. Eye present. Antenna 1 with third joint longer than second, flagella 

 two-jointed. Branchial leaflets numerous, in a straight series. Maxilliped 3 

 with second and fourth joints distally produced laterally, the fifth distally 

 widened in the medial direction. Second and third peraeopods in both 

 sexes carrying imperfectly developed exopods. Pleopods of male with lateral 

 margin of endopod not produced into a narrow process. Endopod of uropods 

 two-jointed, first joint the longer.
