ward in the subgenus Calanopia. It was transferred to the present 
genus by Brady in the Challenger plankton and appeared in Rose’s 
portion of the Monaco plankton, but not in the other lists. Dana re- 
ported this species off Constitucién, Chile, in immense numbers, 
40,000 to 50,000, but in the other planktons it was very rare. Sars 
identified these Albatross specimens from the single station off Peru.

Station 2236. Wheeler based his new species upon four females 
taken in a surface tow off Marthas Vineyard. It is found in only one 
of the plankton lists but has been reported by Esterly (1905, p. 172) 
from the California coast, by Farran (1929, p. 255) from off New 
Zealand, and by Bigelow (1924, p. 219) from the Gulf of Maine. In 
the Challenger plankton Brady reported it under the specific name 
wiolaceus from the Philippine Islands and the southern Pacific. 
Brady’s name had already been given to another species by Claus, and 
so Wheeler changed it to the above.

specimens collected near El Gran Cocal in the Ellice Islands; present 
in the Siboga and Carnegie planktons but not in the Monaco or 
Challenger plankton. Dana recorded the color of living specimens 
as “bluish, with a reddish tint in the head and abdomen,” but in the 
preserved specimens these colors have long since disappeared.
