This is only a rather wide, yonng 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. 



{'Described by Mr. La as a smooth species, but among a hundred perfect specimens before me, 

 over eighty are more or less plicate on the spire.
