Globigerina pseudo-bulloides Plummer, Univ. Texas BuU. 2644, 

 p. 133, pi. 8, figs. 9a-c, 1926. 



Test free, medium sized, low trochospiral, coil of 

 about 2K volutions, umbilical side with small deep 

 umbilicus; chambers subglobular and inflated, increas- 

 ing rapidly in size, 5 to 7 in the final whorl, most 

 commonly 5; sutures distinctly constricted; wall cal- 

 careous, distinctly perforate and very finely pitted, but 

 not spinose; apertm-e extraumbilical-umbilical, interio- 

 marginal, a rounded arch bordered above by a narrow 

 lip.

Remarks: Globorotalia psevdobulloides differs from 

 6. varianta (Subbotina) in having a more coarsely per- 

 forate and finely pitted wall which may give the appear- 

 ance of being reticulate, but does not have the finely 

 spinose surface of the associated G. varianta.
