This is the commonest and largest land shell of the boreal American 

 region, passing through many mutations, but easily recognizable in all 

 of them ; often with a rich coloration varying from olive brown to 

 orange and usually lineated with more opaque lighter axial streaks. I 

 do not regard it as identical with the S. lineata of W. G. Binney, 

 though the species have some characters in common.
