Resembles jB. Virginea, but is rather larger, less polished, and 

 the pillar is not so distinctly truncated ; the shell is white 

 and variously banded, but the colours are usually less mixed 

 than in the foregoing species. It has not been ascertained 

 whether this is a land or fresh-water species. Chemnitz's 

 shell referred to for a Variety may probably be distinct, and 

 both its aperture and general appearance approaches still 

 nearer to a Helix. 



strigata. 47. Shell conical, acuminated, glabrous, 

 with undulated yellow streaks ; pillar straight, 

 reflected.

Shell two and a quarter inches long, and one inch broad, white, 

 glabrous, without any distinct striae, and marked with waved 

 equidistant yellow streaks ; whirls eight, not so much pro- 

 duced as in B. striatula, between which and B. fasciata 

 this is an intermediate species ; pillar perforated, straight, 

 and reflected ; aperture ovate-oblong, of a pale bluish co- 

 lour. Bruguiere suspects that this is only a Variety of jB. 

 striatula. 



striatula. 48. Shell conical, white, and striated ;
