Hab. L. Marques. Matolla (Penther). 



I have not seen Penther's shells and have no idea to what species they 

 really belong. Cressy has collected on Mount Vengo specimens of this 

 genus which appear to be quite distinct from C. acicula (Miill.) or from any 

 of the African so-called species, but the material so far received from him 

 is not quite sufficient for its exact determination.

Hab. L. Marques. Lebombo Mts., under bark of shrubs (Junod) ; 

 Lake Zandemela (Lawrence). 



The type set of plafiti in the British Museum are simply very immature 

 examples of striata, which is partial to so many dry and exposed positions 

 that it is far more often found in an immature than a mature stage of 

 growth.
