helix. 51 



at its termination. Aperture reddish, nearly lunate, equal 

 in breadth to half the basal diameter, rather inferior in 

 height. Peristome acute, very little reflected, a little 

 dilated upon the columella, its internal rib white or pale 

 rose-coloured. Base convex ; umbilicus deep but rather 

 small, not concealed by the pillar lip. 



Diameter about three quarters of an inch. 



The animal is of a general greyish hue, becoming darker 

 on the head and neck, where it is tinged with brown. 



It is chiefly to be found among brambles and by hedges 

 in the district around London and the counties to the 

 south of the Thames. It has been taken in the west of 

 England. The Irish recorded locality is very doubtful. 



H. Carthusiana, Muller. 



Rather small, depressed, whitish, bald ; mouth margined 

 within by a milk white rib; umbilicus minute.
