Type in my collection. 



Ilab. — W'aitakerci, Auckland (Mr. T. F. Cheeseman). 



This species is intermediate between L. transttans and L. lacida. 

 It is distinguished from the latter by the colour-markings, the 

 absence of microscopical spiral striation, and the more opaque texture. 

 L. transitans differs from it in the higher spire, the distinct growtli- 

 lines, and the acute keel at the periphery. 



No figure is given, as the outline of the shell is veiy similar to that 

 of L. lucida.
