of the postabdominal segments rather deep. Last segment scarcely 

 longer than the preceeding ; the præanal spine obsolete. Eyes rather 

 tbick, claviform. Antennular peduncle elongated, provided above. 

 at the end of Ist and 2nd joint, with an anteriorly directed lobe 

 slightly emarginated at the tip. Antennal scale somewhat sur- 

 passing the 2nd joint of the antennular peduncle, elongated oblong, 

 somewhat obliquely truncated at the apex, the denticle on the outer 

 ■edge small but distinct. Telson of the usual form with smooth sub- 

 apical spines. Uropods almost reaching the tip of the telson, inner 

 lamella shorter than the outer. Length: 43 mm. 



Hab. Antarctic Ocean, near the ice barrier, (Stat. 154)-, sur- 

 face. A single specimen, female. 



Remarks. This is, next E. superba, the largest species of Eu- 

 phausia procured during the Expedition. T have much pleasure in

 the Expedition are well known, and who has also been very much 

 interested in the accomplishement of the surfacé gatherings, during 

 the various cruises.

Form of body almost as in the last species. Carapax rather 

 narrow, without any lateral denticle; anterior part very slightly 

 keeled above. rostrum short. and obtuse; frontal margin not forming 

 any distinct angles above the eyes. Postabdominal segments witli 

 rather deep, and rounded epimera; the last short, not exceeding in 

 length the preceeding; præanal spine obsolete. Eyes rather large, 

 pyriform. Antennular peduncle strong, and robust, the dorsal lobe 

 at the end of the basal joint, small, and rounded. Antennal scale 

 short, not reaching the end of the 2nd joint of the antennular pe- 

 duncle, ovate, apex subtruncate, the denticle on the outer edge 

 very small. Exopodites, or natatory branches of the legs, as well 

 as the pleopoda, very largely developed. Telson narrow, with 

 smooth subapical spines. Uropods slightly surpassing the tip of
