The angular lamella is low, very long, almost doubled above ; 

 upper columellar lamella high within, diminishing towards 

 the margin, the lower one immersed. Palatal plicae 4, the 

 upper very small, deep within, second marginal ; second, third 

 and fourth of equal length within, penetrating to about the 

 middle of the whorl. Length 5-6, diam. 1.75 mm. (Wester- 

 lund). 



Several supposed species described from southeastern 

 France, in the departments B.-du-Rhone, Var, Basses-Alpes, 

 etc., are apparently synonyms or perhaps varieties of micheli; 

 the descriptions follow. 



Pupa columnella Loc. Narrowly cylindric, a little taper- 

 ing, quite obtuse at the summit ; 8-9 quite convex whorls, the 

 suture marked. Aperture small, regularly ovate, a little elon-
