First mentioned as occurring in lily tanks at the Royal 

 Botanic Gardens, Kew, by A. Choules in I860. 

 Choules adds that he had collected the shell twenty 

 years previously in the vicinity of the metropolis 

 when gathering plants for Kew, and this may 

 account for its presence in those gardens. (Zoologist,
