[1][2] The specific name, convictus, is derived from Latin, meaning "convicted" or "bound together", possibly referring to the distinct patterning on the snake's body.

The body pattern consists of a brown, yellowish, or gray-brown background, overlaid with one or two dorsal series of large, squarish, dark-brown blotches.
