Reference List of South African Non-marine Mollusca. 287 
The type, in the British Museum, is labelled “ Natal,’ but the 
species is Madagascan, not South African, and the locality is almost 
certainly erroneous.

After careful research, I have failed to trace any authentic instance 
of the occurrence of this species south of the Zambesi.

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 (Miill.), a West African species whose presence in South 
Africa appears to require further confirmation. Brot places his- 
trionica in the synonymy of Claviger balteatus (Phil.) from Senegal, 
which he states is nearly allied to awrita.
