This is ouly a rather wide, young specimen of laqueata, as I have ascertained by the inspection 

 of some hundreds of specimens of that species. 



t Versipdlis resembles a young laqueata, but its texture is rruite heavy although small. 



j Described by Mr. Lea as a smooth species, but among a hundred perfect specimens before me, 

 oyer eighty are more or less plicate on the spire.
