166 EUROPEAN SPECIES OF VERTIGO. 



3-2-2. All from Piedmont (Atti R. Accad. Sci. Torino, xx, 

 1885, p. 686). 



Var. major Locard. Alt. 2-21/4, diam. 114 mm.; 5 folds. 

 Uriage (Isere). (Locard, Ann. Soc. Agricult. Lyon (5), ii, 



1880, p. 855). 



Var. novemplicata Loc. Shell conforming to the type but 

 with a third fold on the penult whorl; this fold is very low 

 and situated near the eolumellar margin, ordinarily quite im- 

 mersed. Alluvium of the Rhone at Lyons (Locard, t. c., p. 

 856). 



Var. cornea Loc. Pale corneous, subtransparent. Environs

Pfeiffer (Monographia ii, 361) mentioned, as a doubtful 

 small variety of V. antivertigo, a Pupa pusilla Bivona fils, 

 Monogr. p. 14; Arad. et Magg., Catal., p. 131. "T. valde 

 parva, ovato-conica, apice obtuse, corneo-ruf escente ; anfr. 4 

 5 convexis, suturis impressis; aperture 6- vel 7 dentata, 

 latere dextro sinuosa ; margine reflexo. Long. y 2 lin." (Ar. et 

 Magg.). It is from the river Oreto, Sicily. The name is 

 preoccupied. Benoit (Nuovo Catal. Conch, terr. e fluv. Sicilia 



1881, p. 99) remarks that two varieties of Pupa antivertigo 

 have been observed in Sicily, the larger one living at Madonie, 

 the smaller on the banks of the Oreto river. If really as small 

 as stated, this is evidently a distinct species. 



Vertigo sinuata Mousson (pi. 16, fig. 7). Shell small, dex- 

 tral, rimate, globose-ovate, slightly striatulate, pellucid, glossy, 

 pale corneous. Spire convexly conic, the apex obtuse, suture 

 somewhat impressed. Whorls 5, rapidly increasing, the penult 

 largest, inflated, the last ascending a little, tapering below, 

 more distinctly striate, in the middle of its alt. acutely im- 

 pressed and having a transverse wrinkle. Aperture small, 

 vertical, irregularly semioval, conspicuously sinuate above on 

 the right, internally 7-toothed: 2 distinct and a third rudi- 

 mentary parietals. 1 long in the post-sinual angle, 1 deep, 

 elongate and another shorter in the lower margin, finally a 

 seventh, immersed, on the columella. Peristome rather ob- 

 tuse, a little reflected, labiate within; margins somewhat ap- 

 proximate and converging, joined by a somewhat callous la- 

 mella, the right bisinuate, the angle projecting strongly into
