Xll PUPILLID^E. 



Distribution. 



The discussion of distribution is deferred until the conclu- 

 sion of the monograph. The genera of Gastrocoptinae range 

 as follows : 



Palaearctic Region : Gastrocopta, Odontocyclas, SandahUa, 

 Abida, Granopupa, Cho-ndrina. 



Ethiopia Region : Gastrocopta, Fauxulus. 



Oriental Region : Gastrocopta, Hypselostoma, Boysidia, Gy- 

 liauchen, Aulacospira and Systenostoma. 



Australian Region: Gastrocopta. 



Nearctic Region : Gastrocopta, Chaenaxis. 



Neotropic Region : Gastrocopta, Bothriopupa, Gibbulina. 



Gastrocopta is thus the only genus found on all the conti- 

 nents. All the others are confined to single faunal Regions.
