"The colour of the upper parts of the body must be considered a8 

 black, variegated with brown spots, which are nut of a uniform shade, 

 but pass from dark into a Lighter colour; they are irregularly scat- 

 tered over the body; nevertheless, they exhibit a tendency to run 

 from one side toward the other, widening towards the hack. The 

 light spots are composed of smoky gray, passing into blackish brown, 

 exhibiting all the intermediate shades between these two colours; 

 they arc rather small stripes of the breadth of from two to four 

 scales, and disappear near the tail altogether, which is entirely black, 

 having only four small white points, which are probably accidental." 

 Top of head black, whitish behind the eye. A band from the eye 

 above posterior labial. Belly whitish, blotched with black. 



Mountain region from Virginia southward.
