taking up at least one-half the area of the test; sutures slightly de- 

 pressed, limbate above and below, wall rugose or granular on the 

 dorsal side, smooth below. 



Diameter about 0.5 mm. 



Distribution.-- -The only published record for this seems to be that 

 of Brady from the Challenger station off the Philippines in 95 fathoms. 

 I have questionable specimens from Nero station 1073 in 1,208 

 fathoms.

Description. — Test biconvex, somewhat elongate, twice as long as 

 wide, composed of few chambers in the last-formed coil; chambers 

 rotund; sutures deeply depressed; wall smooth except for the rather 

 coarse punctse; aperture on the ventral border of the margin of the 

 chamber. 



Length about 1 mm. 



Distribution. — Apparently this species has not previously been 

 recorded from the North Pacific. I have material from Albatross 

 station D4966 in 290 fathoms, bottom temperature 44.1° F., off 

 Japan. 



This species may be distinguished from Pulvinulina auricula by its 

 much more rounded contour.
