pagos. Identified by Sars at 7 of these Albatross and at 4 Monaco 
stations and present in the Carnegie but not in the Siboga planktons. 
The species has been considered a cold-water form. Sars (1925, p. 
198) has reported it from the Arctic.

from 11 of these Albatross and from 8 Monaco stations and found in 
the Carnegie plankton. It isa more temperate form than the preced- 
ing species and is often captured in surface tows.

[Station 5320. There is a single female from this station in the 
China Sea in the Albatross collection (U.S.N.M. No. 74891). The 
species was originally described from female specimens from the 
Atlantic; A. Scott also recorded a single female from the Pacific in 
the Siboga report. Sewell (1913, p. 354) found both sexes in the 
Indian Ocean and later (1932, p. 249) gave a detailed description.—

Sars from 26 of these Albatross and from 56 Monaco stations and 
present also in the Siboga and Carnegie planktons. Although found 
more often in the warmer portions of the oceans, this species has been 
reported from the Antarctic (Wolfenden, 1911, p. 287; Farran, 1929, 
p- 258).
