 posterior margin, that is not prominent in the raiddle with the 

 outer angles acute, though short; anterior pair of spinules placed 

 far before the middle. 



Anten nular articles in the proportion of 6:4:3, stylocerite 

 reaching to the second 3rd or 4th part of median article. Carpo- 

 cerite slender, 5,5 times longer than thick, surpassing the anten- 

 nular peduncle by the whole length of distal article; terminal 

 spine of scaphocerite also longer than the antennule, scale very 

 narrow, reaching to extremity of median article. Inferior spine of 

 basicerite slender, longer than the stylocerite, upper spine well 

 developped. 



Third legs as in Sr/n. pachymeris, but the propodite a little 

 longer and more slender with regard to the other joints ; relative 

 dimensions of 3rd legs: Meropodite 2,7 — 3; carpus 1; propodite 

 1,8 — 2,2. Proportion between length of meropodite and propodite 

 1,4 — 1,6. Meropodite 3,26 — 3,6 times longer than wide with 

 5 — 7 small, movable spinules on posterior margin; propodite 

 4,55 — 5,4 times longer than wide. Dactylus '/o — V? °^ ^^® propo- 

 dite, dorsal hook twice as long and one and a half as wide at

 Archip. 1905, p. 874, PI. LXXI, Fig. 10). 



Rostrum a little more than one and a half as long as wide 

 at base, reaching to the middle of the visible part of Ist. anten- 

 nular article, lateral spines one fifth shorter, projecting straight 

 foreward. Antennal region as in the quoted species, but the three 

 articles of the antennular peduncle, which is 4,3 times as long as 

 thick, are in the proportion of 8:5:4. Stylocerite as long as
