A very small shell, brought up occasionally by the dredge from 

 10 fathoms ; sandy bottom. The other Tasmanian species is C. 

 arachis, which is Australian also. In its young state it can always 

 be distinguished from the foregoing by the dense undulating trans- 

 verse stride with which it is covered (T'-TF.).

Shell elongately ovate, umbilicated, rather thin, white, irregular- 

 ly and faintly longitudinally striated, the stride more distinct and 

 equal near the apex, transversely ornamented with numerous rows 

 of very fine close-set, crenate, interrupted lines, which, together 

 with the longitudinal stride, become very nearly obsolete towards 

 the center ; apex perforate, somewhat tumid around the perforation ; 

 aperture narrow above, wider below ; outer lip thin, simple ; colu- 

 mella short, smooth, very slightly expanded over the umbilicus* 

 Length 6, breadth 3 lines (Ang.).
