Euphausia superba is known to form a large part of the food of the crab-eating 
seal. Lobodon carcinophaga and of the Antarctic penguins, but I am not aware that it 
has been previously recorded from Weddell’s Sea, Leptonychotes weddelli, or from any 
of the Antarctic fishes.

Locality. 
From the stomach of Trematomus eulepidotus Regan, No. 18, several specimens 
in a somewhat fragmentary condition. This species comes very near to Euphausia 
jrigida Hansen, but may be recognised by the much longer rostrum and by the absence 
of lobes on the distal extremity of the basal joint of the antennular peduncle. The 
copulatory organs on the first pleopods of the male are very similar indeed to those 
described by Hansen for his species. 
E. crystallorophias was captured in enormous numbers by the “ Discovery,” 
from holes made in the ice at Winter Quarters on Victoria Land, to the east of the area 
explored by the “ Aurora.” It has only been recorded by one other South Pole Expedi¬ 
tion, the “ Belgica,” having captured three young specimens in about lat. 70° S., long. 
82° 37' W.
