The first two or three whorls are slightly adherent, but the 

 shell becomes rapidly uncoiled ; the fissure is very long, prominent, 

 wide, and the sides are irregularly cut ; the lines of growth form 

 corrugations and small cracks, and are somewhat scaly ; spiral 

 lineations very faint except on the under-surface, where they are 

 broken up into short lengths. The ornament is, therefore, of an 

 exceedingly simple character. 



Dimensions. — Extreme length 34 mm. ; breadth of aperture 6 mm. 



Form, and Loc. — Eocene : Muddy Creek, Victoria.
