FOEAMTXTFERA OF NORTH PACIFIC OCEAN, 



91 



sionally bifurcating; aperture terminal, central, circular, situated in 

 the center of the depression at the apertural end; color, white. 



Length 0.50-0.80 mm. 



Distribution. — The only North Pacific record for this species is 

 given by Bagg, Albatross station H4694, in 865 fathoms, off the 

 Hawaiian Islands. I have had material from Alba- 

 tross station H2922 in 268 fathoms, also off the 

 Hawaiian Islands. 



The species seems to be a tropical or subtropical 

 one, being found in the area from northern Australia 

 through the South Pacific and Malay Islands, a not 

 uncommon distribution for other species found in 

 the Hawaiian waters.

Description. — Test elongate, made up of chambers 

 from one side biserial, from the other more or less 

 spiral or irregular; wall calcareous, perforate; aper- 

 ture large, comma-shaped, on the inner portion of the 

 chamber; color, white. 



This genus, including but a few species, has a wide 

 distribution in the present seas and is found fossil 

 especially in the later tertiary. On the one hand it is related to 

 Bulimina, and on the other hand many of its characters are not 

 unlike Bolivina, especially the aperture.
