DISTRIBUTION OF PUPILLIDAE, 147 



Eastward, in central Asia, the Palaearetic Region has only 

 a scanty fauna, listed on p. 148. In China and Japan there 

 is a somewhat richer fauna, resembling the Miocene of Europe 

 in the copious development of Gastrocopta and Gibiulinopsis.^ 

 Vertigo also is well represented. 



In the following list of the genera of the European system, 

 those restricted to that region are starred (*). References 

 are added to volume and page where the genera and species 

 are described. The geological age of first appearance is added.

The following genera occur fossil in the European Tertiary 

 but are now either extinct, or are no longer living in the 

 European fauna. Genera starred (*) are extinct and endemic. 



Gastrocopta. 24 :112. 

 Alhinula. Middle Oligocene to Pliocene. 

 Sinalhinula. Late Oligocene to Pliocene. 



Microstele 26:147. Miocene. 

 Enneopupa* 27 :222. Upper Oligocene. 

 Paracoryna* 27 :132, 320. Miocene. 



1 It is rather a pity that the inappropriate name Gibbulinopsis has to 

 be used in place of Primipupilla. See vol. 27, p. 254.
