(Pituophis melanoleuca sayi)
When speaking of these snakes, the local herpers usually refer to them as either "pituophis" or "bullsnakes."
Bullsnakes are fairly common throughout the range of this work. There is some variability in coloration, with the ones from the western part of the range generally being more reddish, while the ones from the eastern part of the range tend to be brownish.
The largest one I have found was in excess of 8'6", found south of Rocksprings in the Hill Country. He was as docile as a lamb.
This specimen is from forty miles northeast of Van Horn.
