quite smooth above, in Q with the hinder half of median carina, rising from 

 back to front and there followed by a row of 3 or 4 little denticles. Pedi- 

 gerous segment 1 distinct doTsally, covered below by advanced sides of the 

 large 2^^ segment. Pleon longer (G. 0. Sars), generally not longer (Caiman and 

 figures by Sars) than the front division of the body. Eye with corneal lenses 

 prominent and much more distinct in d than in Q . Maxilliped 3 as in 

 /. setToia (nr. 5) but perhaps with relatively longer 2"'^ joint and less developed 

 prolongation of the 4tii. Peraeopod 1, 2"'^ joint about as long as or longer 

 than the rest of limb, with both margins showing some denticulation. 

 Peraeopod 2 much as in i. seirata, with which the uropods also agree. 

 L. 9 10 mm, d somewhat less.

Body very long and slender. Pseudorostral lobes comparatively short, 

 horizontal; antero-lateral corners acute in 9 , obtuse in d". Carapace with front 

 half of carina forming several teeth, successively larger to the front, more 

 numerous in 9 than in d. Eye w^ell developed. Antenna 1, 3^ joint longer 

 than 2'1'J, shorter than 1^*, both flagella 2-jointed, the accessory minutely. 

 Maxilliped 3 with process of 4:^^ joint weak and carrying few setae. Peraeopod 1 . 

 the slender 2^'^ joint shorter than rest of limb, 5*^ longer than 6^^ and 6*'^ 

 than 7*^. Peraeopod 2 with terminal joint considerably longer than 2 preceding 

 joints combined. Peduncle of uropods considerably longer than the equal 

 rami, which are similar in armature to those of /. trispinosa, but with more 

 spines (8 instead of 5) on the first joint of the endopod in the male, the 

 joint itself much more than half as long as the second. L. 9 7 mm, 

 d about 8 ram.

Pseudorostral lobes short, with minute apical point, otherwise truncate 

 with rounded corners; antero-lateral corners not produced. Carapace short 

 and stout, with feeble medio-dorsal furrow flanked by pair of weak carinae, 

 which are met at about the middle by a pair of lateral furrows running back 

 from the front and then curving upwards. Median furrow and carinae con- 

 tinued on the pedigerous segments and with diminishing vigour on the first 

 4 pleon segments. Last 3 pedigerous segments with 3 pairs of lateral carinae, 

 2 above and 1 weaker below. Pleon segments 1—4 have also a feeble 

 subdorsal pair of carinae; pleon segment 5 has only a single median keel. 

 Eyelobe broader than long, apically pointed, number of lenses uncertain. 

 Antenna 1, 3<^ joint not longer than 2"^. or than the flagellum, which has 

 a group of sensory filaments on the V^ joint and 2 long- olfactory setae on 

 the 2nd, accessory minute, 1-jointed. Maxilliped 3, 2°'i joint bluntly produced, 

 4*11 ^ith only 2 plumose setae on its broadly rounded, not elongate process, 

 5th fusiform'. Peraeopod 1, 2^^ joi^t little longer than rest of limb, 7^^ nearly 

 half as long as 6*^1. Peraeopod 2 long and slender, a little longer than 

 the 3d. Peduncle of uropods little longer than the subequal rami, with
