Found my confusion. I've always called it a blue-tailed skink.
Southeastern Five-lined Skink- Southeastern five-lined skinks are moderately large lizards with short legs and a streamlined body. The body is generally gray, brown, or black, in background color with five white or yellowish stripes (two on each side and one down the center of the back). Young have a bright blue tail while adult males' stripes may fade and a reddish or orange coloration may develop on the head. Southeastern five-lined skinks may be found on the ground or in trees, but are generally less arboreal (tree dwelling) than broadhead skinks. Although sometimes seen in the open, these lizards are most often found beneath logs or under tree bark. When pursued, these lizards generally run for the nearest tree or log and can be quite difficult to capture. Like many other lizards, southeastern five-lined skinks will break off their tails when restrained, distracting the predator and allowing the lizard to escape.
