FOEAMINIFEEA OF THE NORTH PACIFIC OCEAN. 



11 



sharp; chambers numerous, about six or seven in the last-formed 

 whorl, stout; sutures curved backward, slightly if at all depressed 

 above, ventrally somewhat depressed 

 toward the peripheral border, toward the 

 umbilicus broadly lhnbate, forming a 

 stellate pattern; surface with coarse per- 

 forations, on the ventral side the periph- 

 ery has a bordering carina with radial 

 markings; aperture a narrow slit at the 

 base of the chamber partially covered 

 with a valvular projection. 



Diameter 0.50-0.85 mm. 



Distribution. — Bagg records this spe- 

 cies from Albatross station H4694 in 865 

 fathoms, off the Hawaiian Islands, as 

 rare. The only material I have had was 

 from Albatross station H4882 off Blake 

 Reef, in Colnett or Yincennes Strait off 

 southern Japan.
