COPEPODS GATHERED BY ALBATROSS—WILSON DTT: 
of the type locality. Farran again records it from the tropical Pacific 
(1936, p. 124) and also from the Indian Ocean (1913, p. 184). Not 
appearing in any of the other plankton lists, it is, however, reported 
from the Adriatic near Venice by Pesta (1920, p. 554). The Albatross 
has established its presence in the Atlantic (station 2195), besides tak- 
ing it off Peru, in the Galapagos Islands, and in Japanese waters.

tan Island, Philippine Islands; Fiji Islands. This is probably the 
most widely distributed species of the genus, but in spite of the long 
list of stations it must be classed as comparatively rare in the Albatross 
plankton. In his “Crustacea of Norway,” Sars (1913, p. 8) makes a 
statement that is supported by the present plankton: “Male specimens 
are much scarcer than females, and seem only to appear in certain 
seasons.” The species was included in the Monaco and Carnegie lists.

and figured by Sars (1913, p.6). It appears also in the Carnegie and 
Challenger planktons.
