Silvestria bradyi Schubert, Pal. Zeitschr., vol. 3, 1920, p. 166. 



Chambers in the early stages coiled, later ones irregular, inflated; 

 wall calcareous, imperforate; aperture rounded or variously shaped, 

 without a tooth.

 England by Heron-Allen and Earland, It is much more common in

Genus SQUAMULINA Schultze, 1854 



Squajnulina Schultze (Genoholotype, Squa7nulinalaevis Schultze), Organis- 

 mus Polythal., 1854, p. 56.— Chapman, The Foraminifera, 1902, p. 79.— 

 Cushman, Special Publ. No. 1, Cushman Lab. Foram. Res., 1928, p. 169. 



Test adherent, consisting of a single inflated chamber with the wall 

 calcareous and imperforate; aperture simple, on the convex surface.

This is a degenerate form which from the character of the wall 

 seems to belong with this family. It is known only as a recent 

 species.
