Carapace over 2/5 of the total leugth, slightly compressed, oval 

 in outline as sceu froiu above. Seen from the side the dorsal 

 outline is moderately arched and the short pseudorostrum is sharply 

 turned upvvards and nearly vertically truncated. The antennal notch 

 is small but distinct aud the antero-lateral corner is produced into 

 a small blunt tooth, not broadly rounded as in Bonnier's figure. 

 The dorsal surface is not keeled but immediately behind the middle 

 of its length it bears a strong median tooth. 



Therc is no eye but a narrow ocular lobe with parallel sides 

 cxtends nearly to the end of the pseudorostrum. Seen from the side 

 it is elevated above the dorsal outline towards the tip where it 

 carries a pair of small tubercles. 



The carapace is rather thin and transparent, with a faiutly 

 marked vermiculate texture. 



The first leg-bearing somite is completely exposed. On the 

 dorsal surface its posterior edge is raised into a transverse lamina 

 produced and curving forwards in the middle line where it forms 

 a bifid tooth overlapping the bind margin of the carapace. The 

 second somite is produced into a similar tooth not so prominent and 

 not curved forwards. The pleural plates of the thoracic somites are 

 unarmed, except for a few small grauules. The last two somites 

 are granular on the dorsal surface. 



The abdominal somites are all, except the last, beset with 

 granules, especially on the dorsal and ventral surfaces. The 

 penultimate somite (fig. 14) is hardly inflated anteriorly. The 

 peduncle of the uropods (fig. 14) is about equal in length to the 

 last two somites together and is twice the length of the endopod. 

 The latter bears three rather long spines on its inner edge and a- 

 strong terminal ^)me with a small spinule externa! to its base. 

 The exopod is shorter than the endopod and has a long and slender 

 terminal spine. 



Adult female. Only a single ovigerous female is in the 

 collection and it is in a eondition too bad for description or figuring. 

 The .somites of the abdomen however ditter from those in immature 

 specimens in beiug nearly smooth. 



Adult male (figs. 16, 17) total length 4 mm. 



Carapace a little less than 2/5 of the total length, less deep 

 than in the female. The anteuual notch is shallow and widely 

 open and the antero-lateral corner is hardly produced. The median 

 dorsal todth is much less i)rominent than in the female, and in
