Euphausia splendens Dana. 

 G. 0. Sars, Challenger Schizopoda, 1885, p. 80, PL XIII. figs. 7-17. 



The rostral margin is somewhat less produced than in Sars's Figure 15. The 

 structure of the antennulse is very characteristic ; the joints of the peduncle are 

 not provided with lobes, and from the dorsal face of the first joint springs a 

 fascicle of strong curved setae.
