and the aperture. In antwertigo the neck has a swollen 

 callus, cut above by a scratch-like impression, the furrow 

 between the callus and the somewhat reflected peristome deep 

 and narrow; it has also a differently shaped aperture and 

 more numerous teeth, 6 to 10. 



Var. merita Westerlund. Callus of the last whorl extremely 

 thin, rufous or nearly obsolete ; no groove behind the aperture ; 

 teeth 1-1-3 (2), very small, nodiform. Sweden at Oestersund, 

 Finland at Rissalanranta (Westerl.). 



Var. globula Westerlund. Shell subglobose, extremely ven- 

 tricose, brownish-chestnut, striatulate; 4 very convex whorls, 

 the penult largest, 3 times as large as the antepenult, larger 

 and especially wider than the last; last whorl dilated anter- 

 iorly, having a callus [crest] of the same color, and a small 

 groove on the back. Aperture with 1-1-2 teeth, the parietal 

 small, deeply placed, columellar basal, palatals punctiform, 

 distant, submarginal. Length 2, diam. 2 mm. Sweden, in 

 the province Sodermanland (Westerlund). 



Var. bidentata Jeffreys. Labial or palatal teeth wanting. 

 If this named variety is really a form of lilljeborgi, it should 

 be noted that the name is anterior.

 pressed ; aperture half-round, very obtuse at base ; 2 immersed 

 superior folds of which that in the middle is largest ; 2 deeply

Vertigo baudoni MASSOT, Enum. Moll. Pyr.-Or., 1872, p. 

 72 (not seen). LOCARD, Ann. Soc. Agricult., Sci., Ind., de 

 Lyon, (7),iii, 1896, p. 221. 



This little-known form should be recognized by the 7 teeth 

 and the sculpture ; it may be related to V. substriata.
