Genus PSEUDOPHAENNA Claus, 1863 
PSEUDOPHAENNA TYPICA Sars 
Pseudophaenna typica Sars, Crustacea of Norway, vol. 4, p. 44, pls. 29, 30, 1902. 
Station 3602. Established by Sars upon specimens from the coast 
of Norway and not appearing in any plankton list. This discovery in 
the Bering Sea is its first appearance away from the Norwegian coast. 
Sars regarded this species as a true bottom form in 20 to 50 fathoms, 
but at this station it was taken at or near the surface. 
Genus RATANIA Giesbrecht, 1892 
RATANIA FLAVA Giesbrecht 
Ratania flava GiEssrREcHT, Fauna und Flora des Golfes von Neapel, monogr. 19, 
p. 616, pl. 5, fig. 6; pl. 48, figs. 40-49, 1892. 
Station 5268. [A lot of 10 specimens (U.S.N.M. No. 74107), includ- 
ing both sexes, was identified by Dr. Wilson from this Philippine 
station. He noted the occurrence in his list of species by stations but 
failed to mention it in his text. This appears to be the first time the 
species has been seen since originally described and the first record 
of it from the Pacific—W. L. S.]

In addition to being present at so many Albatross stations, this species 
was reported from several Challenger, 24 Monaco, 45 Siboga, and 14 
Carnegie localities. Dana reported four or five individuals from the 
Atlantic (op. cit., p. 1084). Besides being cosmopolitan in its distri- 
bution, it often swarms in large numbers.
