periphery inflated, well rounded. The base is short, inflated, rounded, 

 and marked by the same type of sculpture as the spire, but here the 

 axial riblets are a little wider, while the broad spiral tumid elements 

 are stronger, the last one forming a peripheral cord. The base is broadly 

 openly umbilicated. The last whorl is solute for about one-fourth of a 

 turn; the parietal wall of the solute portion shows only axial riblets. 

 Aperture very broadly oval, almost subcircular. Peristome double; the 

 outer broadly expanded, a little wider on the lower half of the columella 

 than on the rest, and a very trifle narrower on the parietal wall. The 

 inner is moderately exserted and reflected. The operculum is paucispiral 

 with almost central nucleus, bearing a few calcareous granules on the 

 outside.
