The large pores are similar to what is seen in many other pelagic 

 species. Although usually found as a bottom form this species 

 occurs sparingly as a pelagic form in tow-net gatherings. 



Genus PULLENIA Parker and Jones, 1862.

Pullenia Parker and Jones (type, P. sphseroides (d'Orbigny)), in Carpenter, 



Parker, and Jones, Intr. Foram., 1862, p. 184. — H. B. Brady, Rep. Voy. 



Challenger, Zoology, vol. 9, 1884, p. 614. 



Description. — Test composed of several chambers arranged in a 

 planospiral or oblique nautiloid more or less involute spiral, sutures 

 not greatly inflated, only those of the last volution visible; wall 

 smooth, perforations small and indistinct; aperture a curved opening 

 at the base of the inner face of the chamber. 



Certain of the characters of this genus make it seem related to 

 such genera as Nonionina or Polystomella, especially the former, but 

 no complicated structures have been demonstrated here as occur in 

 Polystomella. Of the three species P. obliquiloculata is most clearly 

 related in form and apertural characters to the Globigerinidae.

Pullenia bulloides Reuss, Denkscnr. Akad. Wiss. Wien, vol. 25, 1866, p. 150. 



Description. — Test subglobular, somewhat laterally compressed, 

 composed of numerous chambers making three to four volutions, 

 each consisting of four chambers, embracing so that the last volution 

 only is visible from the exterior; surface of the test smooth, the wall 

 very finely but indistinctly perforate; aperture a narrow curved slit 

 between the base of the inner face of the chamber and the previously 

 formed whorl. 



Diameter 0.17-0.40 mm.
