upper part of the columellar lip ; finally a fourth, lamelliform, 

 in the middle of the outer lip. These teeth exist only in quite 

 adult individuals. Peristome a little everted. Columellar 

 margin rectilinear, reflected and dilated, the outer lip strongly 

 arched, the margins converging and strongly approaching. 

 Length 6y 2 , diam. 214 mm. (Bgt.).

Pupa massotiana BOURGUIGNAT, Moll, de San-Julia de Loria, 

 1863, p. 18, pi. 2, f. 13, 14 (in Rev. et Mag. de Zool., 1863). 

 Pupa penchinatiana BGT., t. c., p. 20, pi. 2, f. 15, 16. 



Closely related to jumttlensis and farinesii, from which it 

 differs by having a palatal fold and a small parietal lamella. 



Var. penchinatiana Bgt. PL 5, fig. 11. Umbilical crevice 

 more open, and there are two palatal folds, not reaching the 

 peristome, while the single one of massotiana is on the peri- 

 stome and extends a little way inward. Pathway at San- Julia 

 de Loria. 



Pupa penchinatiana has been recorded from the mountains 

 of Kabylia in Algeria (Hanoteau et Letouriieux, La Kabylie, 

 1872, p. 227). Such a distribution appears anomalous, yet, as 

 in the case of Abida brauni, one is perhaps not justified in ex- 

 pressing more than surprise. 



Var. sexplicata Bofill. With 2 columellar folds. Catalonia, 

 at the Escalas de Sopeira; limestone rocks at Pont de Mon- 

 tanyana, and on the margins of the Noguera Ribagorzana 

 (Pupa penchinatiana var. sexpUcata Bofill, Bull. Soc. Malac. 

 France, iii, 1886, p. 160). 



Var. angustata West. Shell broadly perforate, conic, 

 strongly striate, with 7 whorls ; margins of the peristome ob- 

 liquely produced downward, approaching one another; the 

 aperture therefore narrowed below, outer lip strongly curved 

 above. Two lamella on parietal wall, one on columella, two 

 folds in palate. Length 7, diam. 2% mm. Alcazar, Spain. 

 (Pupa massotiana var. angustata West., Fauna, iii, 1887, p. 

 102.) 



Var. confusa West. Shell ovate-turrited, very finely, very 

 obliquely and closely, regularly striate, dark cherry-brown;
