This species is very common in the Upper Gault of Folke- 

 stone, and the specimens from that formation are very small, 

 with a distinctly hyaline test. It was erroneonsly referred 

 to Bulimina polystropha, having regard to the form and not 

 the texture of the shell. 



One specimen of V. pygmcea was found in the Cambridge 

 Greensand at Swaffham.

This species is very common in the Cambridge Greensand 

 at Swaffham. In the larger-grown tests the white arenaceous 

 surface is prettily relieved by some pale green glauconite 

 granules.
