This is the largest species of the minute Hnneew described in 
this paper. We have seen four specimens, all precisely alike. 
The shell is of the ¢nfans type, and is conspicuous for its 
rounded aperture, the lip bearing a very prominent parietal 
plait ; only one external tooth (the labial), while a deep-seated 
internal plait below the columellar margin is the third and 
only other process observable.
