Shell half an inch long, and about a third as much 

 broad, brown or horn-colour, semitransparent : spire 

 composed of six or seven raised volutions, slightly 

 striate longitudinally : aperture oblong- oval, with 

 the margin white and reflected, forming a slight 

 umbilicus behind the pillar. 



Except in size it is not easy to form a very distinctive 

 character between this and the last species ; but 

 this is of a paler brown, with the volutions more 

 rounded, and the peritreme is white. 



In woods and old walls, and under stones. 



64. B\j LiMvstuherculatus. Shell oval-oblong whitish- 

 brown, white and slightly umbilicate at the base : 

 margin of the aperture white and somewhat re- 

 flected, with a single tubercle at the upper and 

 outer angle.
