This species is especially characteristic of the western Alps. 

 While somewhat related to A. frumentum, it differs by the 

 absence or small size of the spiral lamella (inward from the

 times be seen, however; also by the immersed upper palatal 

 and basal plicae. The spire tapers more gradually, and the 

 surface is almost smooth. 



It varies widely in size in the same lots. The form called 

 sabaudina by Bourguignat (pi. 45, fig. 13) is rather readily
