ART. 6 FORAMINIFEKA: POLYMORPHINIDAE— CUSHMAN AND OZAWA 79 



The variety can be compared with Globulina gibba d'Orbigny var. 

 tuberculata d'Orbigny in its stout spiny ornamentation, but the form 

 of the test and the tapering apertural end will distinguish the two.

Variety differing from the typical in having the surface finely 

 spinose and usually the apertural end fistulose. 



Length 0.40-0.75 mm.; breadth 0.22-0.30 mm.; thickness 0.20- 

 0.30 mm. 



This variety occurs with the typical form in the Cretaceous of 

 Europe and America and is to be distinguished from the typical 

 form mainly by the two characters, the ornamentation of the surface 

 and the peculiar arrangement of the fistulose outgrowths which are 

 somewhat regularly stellate. 



Distribution. — We have specimens from the following Cretaceous 

 localities : Germany, Galling, near Siegsdorf , Upper Bavaria. England, 

 Cambridge greensand, Saxon Cement Works, Cambridge. United 

 States, Navarro formation, clay pit 3 miles south of Corsicana, Tex.
