CLAUSILIA, 305 



and auotlier — Garmeria—hns two species in Burma, one in Cliina 

 and one in Cambodia. The remainder of the Indian Clausilias 

 belong to three sections, Fseudonenia having twelve species, Euphn',- 

 dusa claiming nine, and GyUndvoplmdusa with two. Boettger 

 established a subsection AcropUmlnsa, for the reception "'of 

 C. monticola and 0. arnhana, hut without having seen specimens 

 for investigation. As this subsection appears to me of doubtful 

 vahie I ha\e included the species in Eapha'dusa.
