Shell extremely smooth, glossy, and pellucid, of a brown or 

 greenish horn-colour ; body about half the length of the shell ; 

 spire consisting of five slightly inflated volutions, well defined 

 by the line of the suture, and terminating in a somewhat obtuse 

 apex ; aperture oval ; outer lip rather thick, but not marginate, 

 or reflected ; pillar lip a little replicated, but destitute of an 

 umbilicus. Length a quarter of an inch ; diameter one-third 

 its length. 



Not uncommon in Britain in moist situations, residing prin- 

 cipally on the ground, under old trees, and on the banks of 

 ditches. It is also generally diffused throughout Ireland. Mr. 

 Thompson says, it is found under stones on the dry mountain 

 side at Wolfhills, near Belfast ; and adds, " I have obtained a 

 few specimens, of a handsome variety, of a pale gray colour, 

 and transparent, with a white peristome ; in such localities, this 

 shell does not present to the same degree the rich amber 

 colour and brilliant polish, which it does in woods or shady 

 places."
