Subgenus Corasia, Albers. 



According to Prof. C. Semper (Eeise Philippinen, 1874), should be a 

 section of Cochlostyla, not of Helix, as given in my Hand-list, p. 114, The 

 same is recorded, I. c, of the subgenera Aocina, Albers, and Callicoclilias, 

 Hartm. (emend). 



The type species of Axina was not, however; examined ; so I still con- 

 sider this last as doubtful. 



Amphidromus masoni, Godwin-Austen. 

 Journ. As. Soc. Beng., 1876, Dibiri Farbat at 2000 ft. 



This is my species No. 19, p. 127, of Hand-list, where I have erro- 

 neously recorded the species as A. daflaensis. 



Subgenus Beddomea, G. Nevill. 

 Hand-list, 1878, p. 127, type Bid. eeylanicus, Pfr. 



The animal of the type species of this very distinct and well-marked 

 group was described by E. L. Layard (Ann. Mag. 1853), as "of a brilliant 

 green colour, visible through the shell; it feeds on the Coffee Plant." The 

 group is recorded in Pfeiffer's Nomenclator (ed. Clessin), 1879, as part of 

 the section Fhenyus of the genus Cochlostyla !
