(Figs. 12, 12a.) 



Station 57. 



Anterior region of the carapace rather convex ; rostrum promi- 

 nent, broadly triangular in outline ; the subacute apex is slightly 

 bent downwards, and projects be- 

 tween the bases of the ocular 

 peduncles ; the upper surface has a 

 short median ridge bounded on each 

 side by a shallow groove ; the sides 

 are thin, somewhat elevated, and 

 adapted to the bases of the eye- 

 stalks. Posterior region of carapace 

 a little broader and about equal in 

 length to the anterior portion. 



Cervical groove well marked ; the 

 cardiac area is rather broad, distinctly 

 circumscribed and six-sided; at each lateral angle is situated 

 a Y-shaped plate with the base directed posteriorly. 



Ocular peduncles 0-8 mm. long and 0-4 mm. in diameter; they 

 are slightly curved, and a little narrower at the base than at the 

 summit; cornea round, black, becoming greenish-blue at the 

 junction with the peduncles. Peduncle and flagellum of first 

 antenna about 1 mm. long ; joints short, stoutish and subequal ; 

 smaller flagellum with three or four articuli, each tipped with a 



Carapace x 8.
