Reference List of South African Non-marine Mollusca. 287 



The type, in the British Museum, is labelled " Natal," but the 

 species is Madagascar), not South African, and the locality is almost 

 certainly erroneous.

Type in British Museum. 



Hab. "CAPE COLONY" (fide Reeve). 



M. & P. remark that M. histrionica was described from Cape 

 Colony on the authority of the Cumingian collection. The type 

 appears to be closely allied to, if not a variety of, Pachymelania 

 aurita (Mull.), a West African species whose presence in South 

 Africa appears to require further confirmation. Brot places his- 

 trionica in the synonymy of Claviger baltcatiis (Phil.) from Senegal, 

 which he states is nearly allied to aurita.
