Helix Rajinesquea Ferussac may be H. gtdaris, as it is 

 included among the group of that species in the Tableaux 

 Systematiques. Deshayes, however, in the continuation 

 of the Histoire refers it to lig-era, as does Pfeiffer in his 

 later works. 



De Kay's figure is too little characteristic to be referred 

 with certainty to any species. 



H. Wardiana is universally acknowledged as a variety 

 of this species. 



Found also in Pennsylvania (Conrad I) and Kentucky 

 (Kennicott I)
