220 VERTIGO. 



Vertigo zschokkei comes nearest to V. genesii Gredler and 

 V. eumicra Bourguignat. It differs from both by the denti- 

 tion, and from the last especially by the smaller size and 

 darker color, as well as by the characters of the mouth. In 

 habits it agrees with Vertigo genesii (Biitikofer).
