So far, then, as our present knowledge wan-ants us in 

 assigning a place to the genus we must be content to let it 

 stand by itself, in all probability as a remnant of a very 

 ancient stock of carnivorous pulmonates which have under- 

 gone considerable morphological modification.

Although various species of this genus occur in Cape 

 Colony, and I have also examples from Zululand received 

 from Mr. Burnup, it is somewhat remarkable that it has not 

 been found in Natal.
