1 There is no evidence that Baird ever described this species which is generally credited to him. 

 Cope (Proc. Ac. Nat. Sci. Phila., 1869, p. 100) mentions it as a variety of Plethodon cinereiu, thus, 

 " Var. y. dorsalis, Baird, M.S. 3776. Louisville, Ky.; Salem, Mass." This reference is a nomen nudum 

 pure and simple. 



2 Green described this species and also named the synonymous erythronotus upon the same page. 

 It therefore remained for the first reviser to fix the correct name for the species. This Tschudi did 

 in 1838.
