86 HELICID^E. 



BULIMUS. Scopoli. 



Shell spiral, produced, oblong, ovate or turreted ; smooth 

 or rough, not shining or glassy ; aperture entire, longitu- 

 dinal ovate, simple or toothed ; columella entire ; peristome 

 simple or expanded. 



Animal exactly similar to that of Helix, and having a 

 similar dentition. 



The large and beautiful assemblage of land-shells in- 

 cluded under the genus Bulimus is separated from Helix 

 more on account of general habit than because of pos- 

 sessing distinctive characters of much importance. Our 

 few British species, all of small size and ordinary aspect, 

 are easily enough distinguished generically, but among 

 exotic forms there are many, the true position of which, 

 whether in Bulimus or in Helix, is a matter of doubt. 

 The distribution of the Bitlimi has been made the subject 

 of a valuable and interesting memoir by Mr. Lovell Reeve. 



B. acutus, Muller. 



Turreted-conical, white or clear brown, often with dark mark- 

 ings. Body whorl comparatively short.
