The specimen from East Pondoland, whilst more tlian usually 

 elongate, is sufficiently characterised by the limbation of the sutures 

 and a minute umbilical protuberance indicating the presence of a 

 megalosphere. The latter feature is also seen in Eeuss' specimen 

 from the Upper Cretaceous of Gosau, Eastern Alps. The Gault 

 specimens are more spherical in outline, but possess similar super- 

 ficial ornament. G. suhalata has also been recorded from the 

 Neocomian of Germany, and under the name of G. megalopolitana 

 it has been figured from German (Neocomian and Tertiary) and 

 Enghsh (Neocomian, Gault, and Eocene) fossils respectively.

One or two somewhat broken tests occur in the washings, which 

 show the internal septation of a Polymorphina allied to P. gibba. 

 The reason of these specimens being fractured is the infiltration of 

 the shell with pyrites, which splits the test by its decomposition and 

 expansion. The oral aperture in one specimen is seen to be stellate.
