In hedges in sandy and chalky districts. Kent, 

 Surrey, Hampshire, Dorset, Hertford. Now common 

 near Newcastle. 



Animal grey, above warty, brown. 



Shell about three quarters of an inch in dia- 

 meter, irregularly striate transversely, Fig. 35. 

 thin and nearly transparent, of a pale 

 yellowish-white or lead-colour, rufous 

 about the mouth and underneath ; the 

 lower volution tumid and well rounded, not carinated, 

 but mostly marked with an obscure pale band in the 

 middle ; aperture semielliptic, as wide as long, with 

 a thin but not reflected margin; the internal rib 

 white or rosy; umbilicus small, (fig. 35.) 



The young shells are very pale, pellucid, and with 

 a rather hispid periostraca. 



Ferussac was at first inclined to consider this 

 species as distinct from any of the continental shells 

 (Journ. Phys. xc. 300.) ; but he afterwards considered 

 it as a local variety of H. carthusiana of Drap. 

 All the French specimens I have seen are very 

 different from our shells, and I think they want 

 further examination ; at any rate Lister's and Mon- 

 tagu's names have the priority, and H. carthusiana
