•This is only a rather wide, yoiiufr specimen of laqucoto, as I have ascertained by theinapectioa 

 of some hundreds of specinieus of that species. 



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



% DesiTibeil by Mr. Lea as a smooth speries, but among a hundred perfect specimens before me, 

 over eighty are more or less plicate on thcspiro.
