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

 of some hundreds of specimens of that species. 



t Versipellis resembles a young laqueata, but its texture is quite heavy although small. 



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

 over eighty are more or less plicate on the spire.
