flat near the suture, rounded at the periphery ; base convex. 

 Suture not much impressed. Aperture circular, peristome con- 

 tinuous, solid. Umbilicus \\'ide and perspective. 



Altitude, r5 mm. ; diameter — maj., 2-5 mm. ; min.. 2 mm. 



Type to be presented to the Colonial Museum. 



One specimen only was gathered. I fully agree with my 

 friend Mr. Hedley that this species is nearly allied to C. tatei, 

 Angas, from South Australia, but the latter is larger, has a more 

 elevated spire, the spiral ridges are less numerous, more dis- 

 tant on the upper side, and the interstices are ornamented with 

 close fine and oblique radiate striae, a feature totally wanting 

 in our species ; there are only faint incremental lines. I found 

 this shell also in sand from Lyall Bay.
