This species also closely resembles^', ? diplodon, but the apertui'e 

 is edentulous and the base flatter; the spire, too, is rather 

 lower. 



Major diam. (according to Beuson) nearly 9, min. 8, axis 

 5^ mm.

The shell called S. ? harmeri, var. anodonta, has a descending 

 last whorl near the mouth, wliilst H. gcdea was described as having 

 the last whorl not descending ; the spire, too, in the latter is 

 lower : but it appears probable that the two are identical.
