BU LIMITS. ScopoU, Lamarck, Sfc. 



Cen. Char. An univalved, subturreted, ovate 

 or oblong shell ; aperture longitudinal, en- 

 tire, longer than wide, with the edge of the 

 outer lip reflected when old; columella 

 smooth, neither truncated nor expanded at 

 the base ; no operculum. 



A GENUS of shells belonging to land animals, very 

 closely allied to those of the genus Helix, and equally 

 destitute of opercula ; it is well distinguished by the 

 longitudinal position of its entire aperture, the inner lip 

 of which is closely applied to the columella, and the edge 

 of the outer one, when fully formed, reflected ; the want 

 of an operculum is also of importance, but is not gene- 

 rally useful, because it is a negative character not easily 



proved. 



The species are numerous, the warm climates supply- 

 ing many large kinds, but the temperate chiefly small 

 autl even minute ones : there are several fossil species 

 described by Lamarck as found near Paris. 



The Bulimus roseus, a species 4 inches long, is said 

 by Montfort to be excellent food.
