Var. cristallina (Dupuy). PL 46, fig. 3. 



Shell of a transparent white resembling that of Helix cristal- 

 lina; color of the animal pure white, the tentacles and back 

 somewhat gray (Dupuy). The shell has one tooth on the right 

 margin, thickened below, with a sinus in the upper part, colu- 

 mellar margin with 4 teeth, two large and two small. Two of 

 these teeth continue as milk-white lamellse in the interior of the 

 shell. None of the specimens have an inner tooth in the right 

 margin. Length 6 to 7, diam. 2 or 3 mm.

Pupa goodaill var. cristallina [sic] DUPUY, Essai sur les Mol- 

 lusques terr. et fluv. du Department du Gers, p. 43 (1843). 



This name was evidently based on albino examples of what 

 was described later by Dupuy as A. nouletiana. Similarly col- 

 orless examples occur at Ilkley (fig. 3) and probably other 

 places in England. 



Var. trigonostoma Fagot. Shell rather ventricose, oblong-ovate, 

 reddish-corneous. Whorls 7, scarcely convex, rather rapidly 

 increasing, the last large, compressed below and somewhat 

 angular. Aperture lunate-triangular, with the parietal and 

 columellar lamellaa as in mabilleana, and with a small marginal 

 tooth exactly opposite the parietal lamella; no palatal teeth; 

 outer margin weakly excised above. Length 6, diam. 3 mm. 

 (Westerlund).

Var. bourguignati Fagot. Shell lengthened-oblong, fragile, 

 corneous. Whorls 8%, flattened, slowly increasing, the last 

 scarcely larger, hardly one-third the total length, contracted 

 below. Aperture obliquely piriform, nearly triangular, very 

 narrow and pointed above on the right, with the parietal and 

 columellar lamellae as in mabilleana but weaker ; without teeth
