lower one is larger; three palatals, strong, very long within, 

 joined to the lip-callous; peristome thick, reflected, white- 

 lipped, exteriorly white calloused. Length 7-8, width 2y 2

Italy: Limone, north of the Col di Tenda, in the Alpine 

 zone, Piedmont (H. Blanc).

Differs from mortilleti (stabilei), according to Pollonera, 

 by the less robust angular lamella, and the three palatal plicae 

 which extend to the peristome without interruption; the 

 peristome is thicker and reinforced outwardly with a whitish 

 callous. 



Figures have been published by Caziot (Moll. terr. et fluv. 

 Monaco, pi. 9, f. 17, 18), but they are too small and indistinct 

 to be of use. 



As there was no prior Torquilla or Abida named blanci, the 

 name is valid. It is not a homonym of Pupa bland Bourguig- 

 nat. The substitution of limonensis by Westerlund was there- 

 fore superfluous. 



The description of Pupa limonensis West., from the same 

 locality and collector, here follows. 



Shell rimate, cylindric-fusiform, nearly smooth, glossy, 

 horn-colored. Whorls 9, scarcely at all convex, the last some- 

 what compressed below, whitish and thickened near the aper- 

 ture. Aperture semielliptical, with 7 lamellae and plicae: 2 

 parietal lamellae (the angular moderate) ; columellar lamellae 

 2 (either both deep within, very small, or the upper small 

 and tooth-like, the lower drawn out towards the margin). 

 Palatal plicae 3 (long, strong, marginal, prolonged inward far 

 beyond the middle of the whorl, the upper two even around 

 to the columellar margin). Peristome somewhat reflected, 

 white-lipped, almost separated. Size up to 8 mm. long, 2% 

 wide (Westerlund).
