DISTRIBUTION OF PUPILLIDAE. 149 



Japan, Korea and China. 



North China Pupillids are enumerated above. The fauna 

 of south China is included here for convenience ; hence such 

 Oriental Region genera as Hypselostoma and Anauchen. 

 Boysidia and Pupisomu enter the lower border of the Palae- 

 arotic Region. The Gastrocopts belong to subgenus Sinal- 

 iinula. Microstele (28:137) appears to be represented in the 

 Chinese Pliocene, but is now confined to the Oriental and 

 Ethiopian Regions. Truncatellina, living in the Riukiu 

 Islands, is only known as a fossil on the Chinese mainland 

 (28 :108). Vertigo seems to be rare except in northern Japan. 

 Ptychalaea, a genus of the European Miocene, is represented 

 by a single living species on the Bonin Islands. 



No Pupillidae are yet known from Fonnosa or Hainan.
