straight, forward! y directed medio-ventral spine, the spines becoming 

 smaller posteriorly, on 7th segment nearly obsolete. Side-plate 1 

 acutely produced forward in both sexes, 2 larger than 3. 



Pleon segment 3 with postero-inferior angle rounded quadrate. 



Telson as broad as long, with 2-3 setae in each subapical notch. 



First antenna longer than 2nd, 2nd joint a trifle longer and much 

 more slender than 1st, 3rd half the 2nd, flagellmn 12-jointed, accessory 

 flagellum equal to first 2 tiagellar joints, 3-jointed, 3rd joint very minute. 



Second antenna, gland-cone not very prominent, penultimate and 

 ultimate joints subequal, flagellum a little shorter than ultimate 

 joint, 5-6- jointed. 



Mouth-parts similar to those of L. kergueleni Stebbing. 



First guathopod in <3> , 2nd joint stout, 5th setose on fore and hind 

 margins, 6th equal to 5th (i.e., along anterior margin) and equally 

 broad, oblong, palm a little oblique, with a stout spine at the defining 

 angle and immediately distal to this a spiuiforni process, a small 

 tooth near the hinge, hind-margin and especially the fore margin 

 setose, finger curved, overlapping the spine, serrate on inner margin ; 

 anterior margin of 5th and 6th joints with a number of small circular 

 marks, from each of which arises a seta. In ? not so stout, hind 

 margin of 5th setose, 6th longer than 5th, oblong, palm transverse, 

 convex, with a strong spine at defining angle, fore and hind margins 

 sparsely setose. 



Second gnathopod in ^ smaller than 1st gnathopod, 2nd joint 

 nearly linear, the distal anterior apex produced as a recurved hook, 

 5th more elongate than in 1st gnathopod, 6th equal to but narrower 

 than 5th, narrow-oblong, very slightly tapering, palm transverse, with 

 a small spine at defining angle, fore and hind margins of 5th and 6th 

 setose, the setae on fore margin arising from little circular marks as 

 in 1st gnathopod, finger overlapping palm, serrate on inner margin. 

 In ? similar to ^,but 2nd joint without hook-like projection, 5th 

 shorter and broader proportionately than 6th, both joints apically 

 setose on both margins, both not so strongly as in <$ . 



First and second peraeopods not specially setose, 2nd-4th joints 

 glandular. 



Third to fifth peraeopods, 2nd joint oval, about twice as long as 

 broad, 6th joint with 4-5 pairs of spines on anterior margin. 



First uropod, peduncle with stout apical spine, inner ramus longer 

 than peduncle, outer ramus shorter, both with marginal and apical 

 spines. 



Second uropod, rami a little louger than peduncle, outer ramus 

 shorter than inner.
