“The colour of the upper parts of the body must be considered as 
black, variegated with brown spots, which are not 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 back. The 
light spots are composed of smoky gray, passing into blackish brown, 
exhibiting all the intermediate shades between these two colours; 
they are rather small stripes of the breadth of from two to four 
scales, and disappear near the tail altogether, which is entirely black, 
haying 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, blotehed with black. 
Mountain region from Virginia southward.
