(/) Shell depressed, subconic, not so glossy as H. cantiana, 

 whitish-horn colour, with a white spiral band just above the 

 periphery ; whorls six to seven, faintly keeled, the body whorl 

 very large ; spire acute, more depressed than in H. cantiana , 

 suture rather deep ; mouth crescent-shaped with a white internal 

 rib ; umbilicus very small. Height -^-ths inch. Among grass 

 on the Kent and Sussex downs, near the sea. Local. 



H. Cartusiana.^ 



(/) Shell depressed, subconic, dull brown, more or less reddish, 

 subcarinated, generally with a white band at the periphery ; spire 

 short, blunt ; mouth semi-elliptical with a white internal rib ; 

 umbilicus narrow, deep. Height ^ths inch ; diameter f-ths to 

 |4ths inch. Under stones in hedge-banks. Common. 



H. ruftscensp* 



(k] Shell suborbiculate, depressed, thin, yellowish-brown, epi- 

 dermis covered with fine white recurved hairs arranged in spiral 

 lines ; whorls six to seven, convex, the body-whorls occupying 

 one-third of the shell ; spire blunt, slightly raised ; aperture 

 crescent-shaped ; umbilicus narrow, deep. Height ^th inch. 

 Among moss, and under stones, etc., in shady places. Common. 



H. hispida. 



(1) Like H. hispida but larger, less globose, hairs more liable 

 to fall off; umbilicus wider. Height J inch. In similar situations 

 to the last. Common. H. concinna 



(m) Shell subglobular, thin, dark brown or pale grey, marked 

 with a few faintly-marked brown streaks, epidermis covered with 

 white hairs ; whorls six, convex, the body-whorl occupying nearly 



67 v. leucoloma, small, peristome and rib white ; rufilabris, smaller, inside rib 

 reddish. 



68 v. alba, entirely white ; v. rubens, more or less reddish ; v. minor, smaller, 

 spire more raised. 



69 v. fusca, light brown ; v. subrufa, reddish, glabrous, thicker ; v. nana 

 smaller, labial rib strong, spire depressed ; v. subglobosa, more globular, thinner, 

 horn-coloured or white, umbilicus very small ; v. conica, smaller, spire more 

 raised ; v. albida, thin, white or colourless. 



70 v. minor, smaller, spire more raised ; v. alba, white. (This species is
