SANDAHLIA. 261 



Orientales), Eians (Var), etc. (Orcula cylindriformis Bour- 

 guignat in coll., Locard, Ann. Soc. d'Agric. Lyon (7), iii, 

 1896, p. 209.) 



The locality Rians (Var) is surely an error, as this place is 

 far out of the range of Sandahlia and in an Alpic fauna. 



Form echthrodes West. (Var. polyodon Moq., not Pupa 

 polyodon Drap. ; form echtrodes West., 1897.) Shell of 11-12 

 whorls; aperture with several little folds between the ordi- 

 nary ones. Villefranche. 



Var. corrugata Loc. Cylindric-elongate, very rapidly 

 tapering at the summit; 11-12 slightly convex whorls, the 

 suture marked; aperture relatively small, long-oval; 2 supe- 

 rior folds, the first bifid, lodged at the suture, the second im- 

 mersed; 2 columellars, attaining the peristome, accompanied 

 by 2 to 4 little peristomial folds ; 4 palatals, of which 3 attain 

 the peristome, accompanied by 3 or 4 peristomial folds ; peri- 

 stome thick, expanded, reflected; shell corneous-fawn, not 

 glossy, ornamented with very fine, regular and close striae. 

 Length 7-8, diam. 2%-3 mm. Villefranche (Pyrenees-Orien- 

 tales). (Orcula corrugata Locard, Ann. Soc. d'Agric. Lyon 

 (7), iii, 1896, p. 209.) 



This is probably equal to echthrodes W. 



la. S. cylindrica curtata n. subsp. PI. 46, figs. 5, 7. 



This form, which I take to be var. curta Moq.-Tand. (not 

 Pupa pyrenaaria var. curta Moq., on a prior page), is a rather 

 well-characterized subspecies. Besides the short shell, of 

 which the last 4 whorls form the cylindric portion, it is pecu- 

 liar in thfc aperture. The little right twin-lamella of the an- 

 gular lamella is very short. The angular proper extends a 

 little way beyond the anterior end of the parietal, and is not 

 continuous with the spiral lamella, which, however, is well 

 developed. The accessory lamellae of columellar and parietal 

 margins are often quite weak, or largely wanting. The inner 

 barrier is dorsal. 



Length 6, diam. above aperture 2.8 mm.; 10 whorls (type 

 fig. 5). 



Length 5.9, diam. above aperture 2.6 mm. ; 934 whorls. 



Length 6.9 mm. (largest specimen seen).
