 upper columellar lamella high within, diminishing towards 

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

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

 lund) . 



Several supposed species described from southeastern 

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

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

 the descriptions follow.
