less acute, 3rd and 4th with antero-lateral angles rounded. Posterior 

 3 segments well distinguished from the anterior ones, the 7th 

 longest, the postero-lateral angles rounded. 



Pleon longer than 7th peraeon segment, longer than broad, oval, 

 slightly tapering distally, lateral margins entire. 



Antenna 1 reaching nearly to end of 4th joint of antenna 2, 1st 

 joint largest, 2nd and 3rd together equal to 1st, but not so stout, 

 flagellum 4-joiuted, not distinguishable from peduncle. 



Antenna 2, 3rd joint with distinct scale, 4th-6th joints subequal, 

 6th indistinguishable from flagellum, which consists of ca. 18 indis- 

 tinctly separated joints and is equal to 4th-6th peduncular joints 

 together. 



Upper lip rather long, apically rounded. 



Lower lip with rather broad lobes, inner apical angles setulose. 



Mandibles, cutting-edge 4-deutate, secondary cutting-edge not 

 visible, spine-row apparently absent in left, in right with ca. 8 spines, 

 palp with the 3 joints subequal, 3rd curved and spinulose along inner 

 margin. 



Maxillae 1 and 2 as in /. capensis Brnrd. 



Maxilliped, 2nd joint twice as long as broad, 4th and 5th broad, 

 6th and 7th much narrower than 5th, inner plate with two coupling- 

 hooks, epipod reaching to end of 4th joint, narrow-lanceolate, outer 

 margin angular. 



Peraeopod 1 stout, 2nd joint flask-shaped, 4th shorter than 3rd, 5th 

 oval, enlarged, palm and hind margin subequal, defining angle obtuse 

 and blunt, palm with 6 stout spines, 6th (finger) equal to palm, 

 stout, inner margin straight, unarmed, 7th short, biuuguiculate. 



Peraeopods 2-7 similar to one another, normal (as in J. maculosa 

 Leech, but rather stouter than in Sars' figures in Crust. Norw. vol. 2, 

 pi. 40), triunguiculate. 



Pleopod 1, peduncle narrowing rapidly from base, thence divided 

 into two divergent branches as long as basal portion, rounded and 

 setose apically. There is no distinction between the basal and distal 

 portions and no suture to indicate the limits of peduncle and ramus 

 (if present). 



Pleopod 2 ovate, apically subacute, ramus arising near apex, peuial 

 filament longer than peduncle. 



Kami of the other pleopods narrow. 



Uropod equal to the greatest width of the pleou, outer ramus shorter 

 and narrower than inner, apically acute, inner ramus apically rounded. 



Length : 3 mm. ; breadth : '5 mm. 



Colour : White, eyes black.
