The transverse lirse are very fine and alternately larger 

 and smaller, and, being crossed by the lines of growth, have 

 a very pretty subgranose appearance. 



The type of this species in the British Museum is of a 

 very pale reddish tint with a narrow whitish line round the 

 middle of the body-whorl and another at the angulation 

 above. In the Ceylonese specimen these pale zones are only 

 just traceable. The lirse within the labrum are about 

 seventeen in number.
