Mollusca from South Africa. 609 
A distinct and select addition to the operculate fauna of 
Natal, differing from its ally, the well-known C. conveaius- 
culus, Pfr., not only in colour and sculpture, but in its 
gradately conical spire and general elevation. 
We may add that the type examples of the above, together 
with the types of nearly all our previously described species 
from South Africa, will be placed’in the British Museum 
(Natural History).
