 This species, though entirely harmless, is commonly regarded as 

 venomous. When annoyed it flattens the anterior portion of its 

 body, and hisses vigorously. Comparison of the above specific 

 description and figures with those of the copperhead (p. 335) will 

 show the numerous points of difference.
