Shell somewhat globose, thin, smooth ; body large ; spire 

 small, consisting of four, a little inflated, but narrow volutions, 

 terminating in a rather obtuse apex ; aperture semielliptical ; 

 outer hp white ; whole surface covered with a shining epidermis, 

 of yellow, citron, or pale olive, with bands in some specimens, 

 and destitute of them in others. 



This species will at once be distinguished from the H. nemo- 

 ralis, by its outer lip being invariably white, and the shell is 

 always nearly a third smaller, and a little more globular. It is 

 subject to great variety in the number and disposition of its 

 bands, which are either black, or very dark reddish-brown. 



It inhabits woods, hedges, and shady places, in almost all 

 parts of Britain and Ireland, but is not so common as the //. 

 nemoralis.

Shell semiglobose; body large; spire small, consisting of four 

 moderately inflated volutions, which terminate in an obtuse 

 apex; aperture semielliptical; outer lip of a pale brownish rose- 

 colour, the inner rib being somewhat darker than the lip, which 

 is rather acute at the edge ; whole surface of a brownish, or 

 citron-yellow, sometimes banded, but more generally plain; the 

 latter almost always with an indistinct, whitish band, running 

 spirally on the upper margin of the body, and continued on the 

 upper edge of the volutions of the spire. 



This species differs in the shape of the aperture, which is 

 more transversely ovate than that of the former two species. 



It inhabits hedges and woody situations, in many parts of 

 Britain and Ireland, but is a very local species. Mr. R. Ley- 

 land, of Halifax, found this shell of a form and size resembUng
