On dry banks, and under stones in hilly places. 

 Animal yellowish-ash, warty above, foot thickish. 

 Shell seldom half an inch in diameter, and a quar- 

 ter of an inch high, rather depressed ; the larger vo- 

 lution sloping to a somewhat carinate edge in the 

 middle, with regular deep transverse striae; colour 

 dull yellowish- white, with regular brown bands, which 

 are often interrupted, and the '/p black; aperture 

 crescent-shaped, as long as it is broad, with the mar- 

 gin thin and not reflected over the umbilicus, which 

 is large and deep. 



Like the preceding, it is equally liable to vary in 

 size, colour, and form, and offers nearly the same 

 variations. It is immediately known from that spe- 

 cies by being more depressed, and strongly concen- 

 trically striated. 



Montagu's names for the two last have the priority. 

 Mr. Alder observes, that he has not seen any Bri- 

 tish variety of this shell similar to H. candidula Stu- 

 der, referred to by Mr. Jeffreys.
