acute. Carapace twice and a half (Norman), about twice (Sars), as long as 

 high, median carina in 9 with 13 to 20 forward pointing teeth, successively 

 larger to the front, where 2 or 3 are sometimes separated from the main series, 

 which may or may not reach the hind margin; in d' (Sars) pseudorostral 

 lobes shorter, more level, antero-lateral corners obtuse, carapace more com- 

 pressed, sometimes entirely without serrate carina, sometimes with one but its 

 serrations not reaching the frontal lobe. First pedigerous segment chiefly 

 visible in dorsal view, 2^^ very large, all five and the pleon segments with 

 median carina. Eyelobe of 9 ending in 2 little points, eye red-brown, with 

 9 corneal lenses in d, those in 9 smaller and less distinct. Antenna 1, 

 3*^ joint longer than 1^^, which is longer than 2"*^, flagellum 1 -jointed, with 

 minute 2-jointed accessory. Antenna 2 of 9 2-jointed with 4 setae on the 

 large 1^* joint. Lower lip, with apices not rounded, armed with 5 peculiar 

 spines. Maxilliped 1. branchial leaflets numerous. Maxilliped 3, 2"^ joint 

 with distal process reaching middle of 4*^, and fringed on medial margin with 

 long plumose setae, the 4^*^ fringed in like manner on lateral margin of its 

 prolongation. Peraeopod 1 slender, 2°*^ joint shorter than the rest of limb, 

 having both margins denticulated (A. M. Norman), denticulation not shown 

 on lateral margin nor mentioned in text (G. 0. Sars), 5*^^ and 7^^ subequal 

 and about one-third shorter than 6*^^ (A. M. Norman), 7^^ figured about one- 

 third shorter than the subequal 5^^ and 6*^ (G. 0. Sars). Peraeopod 2 very 

 short, with a joint missing, the 2 joints succeeding the 2"*^ having each a 

 long apical spine, terminal joint not longer than 2 preceding joints combined. 

 Peduncle of uropods longer than the slightly unequal rami, its medial mar- 

 gin in 9 armed with 12 — 14 long spines, in the d with many more in 

 2 or 3 rows; exopod broad with many plumose setae on medial margin of 

 2"^ joint and round the apex, the slightly shorter endopod with 1^^ joint 

 about twice as broad but little over half as long as 2^^, carrying 3 or 4 

 small and a long apical spine, 2^^ joint fringed in 9 with 13, in d with 

 16 spines, encreasing in size to the apex. Colour pale straw yellow, flecked 

 with brown. L. 9 12 mm, (5 10-5 mm.
