1 Mr. B. C. Miles, of Brownsville, Tennessee, writes me that he has taken 

 this snake in the bottoms. 



2 1 here adopt Fitzinger's genus in good faith. He made Herpetodryas 

 tricolor of Schlegel the type of this genus. Should it prove that Prof. Cope's 

 assertion (Proc. A. N. Sci., Phila.. 1860, p. 560), that this species is generically 

 similar to our vernalis, is incorrect, there seems to be no other generic name 

 strictly applicable to it. Prof. Cope's appropriation of Fitzinger's genus Liopel- 

 tis as his own (Proc. N. Mus., Vol. XIV, p. 620) is not only inconsistent with his 

 well-known views on the " catalogue names " of that author, but is in plain 

 violation of the " Code.''
