This familiar little shell has had various vicissitudes 

 in nomenclature. The namey^/iJa Muller, by which 

 it is best known, was based, according to Beck, who 

 was custodian of Midler's types, upon Helix bidentata Gmelin, while 

 a shell which Muller supposed to be the young, but did not figure 

 or fully describe, was supposed by some of the early naturalists to be 

 our species. Another unfigured species. Helix trochtilus Muller, was 

 thought by Dillwyn to be identical with our fulva, but the measure- 

 ments forbid the identification, and Pfeiffer came to the conclusion 

 that H. trochtilus is identical with the young tip of Btiliminus ob- 

 scurus. Fabricius supposed our shell to be identical with Helix
