This species is quite distinct from any of the other South 

 Africa forms, being remarkable on account of its peculiar 

 shape, recalling somewhat that of certain species of Ancilla. 

 The thin callosity which spreads over the columella winds 

 up the spire and covers the greater part of the surface of the 

 whoi-ls.
