 Warren, Esq., of Dublin ; at Ben Bulben, County of Sligo, by 

 William Thompson, Esq., of Belfast ; and at Miltown Malbay, 

 by W. H. Harvey, Esq.

Shell subglobose, subpellucid, thin, fragile, and of a pale yel- 

 lowish horn-colour ; body ventricose, about a third longer than 

 the spire, which consists of four rather tumid volutions, well 

 defined by the sutural line, and terminating in a slightly obtuse 

 apex ; base well rounded, and provided with a very small um- 

 bihcus; aperture semilunar, its width exceeding its length; outer 

 lip very thin, with a slight internal rib, apparent in the adult 

 condition only ; pillar lip slightly reflected, at the angle, over 

 the umbilicus; whole surface covered with fine, close-set, short, 

 downy, whitish hairs, which, when removed, exhibits the mi- 

 nutely granulated, shagreen-like, glossy exterior of the shell. 

 Diameter a quarter of an inch. 



This species is pretty generally spread over Great Britain. 

 It is found in Wiltshire, Devonshire, Lincolnshire, Cornwall, 

 Dorsetshire, and Northumberland ; and is plentiful among net- 

 tles in the King's Park, at Edindurgh. In Ireland, I met with 

 it at Naas, County of Kildare, and near Downpatrick ; Mr. W. 

 H. Harvey found it about Limerick and Ballitore ; and Mr. 

 Humphreys found it at Belgrove, east of Cork. Professor 

 Forbes says it is common on the Isle of Man. Its habitat is in 

 moist, woody situations.
