The two following- species, which have several characters in common, do not 

 belong to Braunsina. They are only placed here because the material for 

 examination is insufficient for a proper definition. The common characters are as 

 follows : — subplaty-subleptogyral, latumbilicate, laterally anguliradiate, peripherally 

 rectiradiate, subtabulate. In other words, subquadrate whorls, V-script ribs, open 

 umbilicus, flattened periphery, are the common features. The first species is more 

 coarsely costate than the other.

Levigation pronounced. 



The species of the two next genera show somewhat rapid decline of costae, and 

 consequently a marked levigate stage, resembling in this matter Pseudographoceras, 

 which has, however, more of a striate sta^e.
