FORA.MINIFERA OF THE ATLANTIC OCEAN.

Distrihution. — Type-specimen (U.S.N.M. Cat. No. 18881) from 

 Albatross station D2203, in 705 fathoms (1,289 meters), off the 

 northeastern coast of the United States. This species is abundant 

 at numerous stations off the northeastern coast of the United States. 

 It is evidently the same as that figured by Parker and Jones" 

 as Margimdina lituus from the Arctic in 160 fathoms (293 meters), 

 at Nordland, Norway. Flint's specimens were from this same gen- 

 eral region, and it is evidently a species which ranges south, perhaps 

 to the latitude of Cape Hatteras, and in its northern distribution 

 reaches to the Arctic Circle. 



Cristellaria alhatrossi — material examined. 



CRISTELLARIA ALBATROSSI, new species, variety. 



There is a variety of this species in which the keel is usually much 

 less developed and the test more rounded. This occurs at many of 

 the stations with the typical form, as the following table shows.
