Eutainia saurita, B. & G. Catal. N. Am. Serpents (1853), 24. 



This slender and graceful serpent, as far as I know, is confined pretty 

 much to that portion of the United States east of the Mississippi, being in- 

 deed most abundant in the region of the Allegheny mountains. In the far west 

 it is replaced by E. proxima, and other allied species. It is generally found 

 near the edge of woods, and not unfrequently in or about the water, in which 

 it seems perfectly at home. It is unnecessary, perhaps, to say of this species, 

 what is perfectly true of all the New- York species except the rattlesnakes 

 and copperhead, that it is entirely harmless ; its bite, if it should inflict one, 

 being similar in its effects to the scratch or puncture of a pin.
