There appears to be no conchological diiference between the 

 European and Australasian examples of this variable species. 

 Typically, the shell is not so oblique as L. helcheri; radial linea- 

 tions are barely perceptible (or absent) in many individuals. The 

 writer agrees with Professor Tate (o^. supra cit., 1886) that 

 L. zealandica, Hutton, is a synonym. 



Dimensions. — Height 21 mm. ; length 22'5 mm. 



Form, and Loc. — Miocene : Awamoa, New Zealand.
