Th.i appears, on further examination, to be only a more 

 largely umbilicated variety of the preceding species.

The rapid Helix. Shell largely openly umbilicated, 

 flat-spired, subdiscoid, homy, transparent, brightly 

 profusely waved with reddish-chestnut, streaks next 

 the suture few and large, very finely decussated

 three to four, convex ; aperture lunar-circukr ; lip 

 simple. 



Pfeiffer, Pro. Zool. Soc. 1853. 



Hab. New Zealand. 



A gracefully convoluted, viudly marked, homy shell, of 

 subdiscoid growth, and concavely flattened spire.
