BOETXGER : ON NKW AFRICAN LAND SHELLS. 349 



This new sub-species of the widely distributed 2'hapsia calamichroa, 

 Jon., differs from the type in having a more depressed spire and 

 being therefore flatter. I received this fine shell from Mr. M. 

 Stahlberg, Schwerin.

Hah. — Kipatimu, German East Africa. 



This new variety differs from the type by its slender shape. 



Edentula affinis is most closely related to the variable Edentulina 

 ovoidea, Brug., but can easily be distinguished from that species by 

 its smaller size and flatter whorls. It is also rather more perforate, 

 and has a flatter suture which does not ascend so much at the
