A dark colored Colubrid with three distinct light stripes running the length of its body; one centered dorsally and the other two located laterally. The lateral stripes are uniquely placed three scale rows dorsally from the ventral scales, and partially including the second and fourth scale rows. It grows to a length of 15-20 inches and has a somewhat small head compared to other garter snakes. Rather than escaping, this species is known to violently squirm in place when threatened.
