Goode's Horned Lizard is one of the smallest species of the genus. It attains a slightly larger size than the P. modestum, the Little Horned Lizard. The spiny scales of the back are but slightly protruding and the general aspect is that of a toad-like creature with quite smooth, granular skin. The ear drum is covered with granular scales. Two rows of marginal, spiny scales, but the lower is very fine and small. Scales of the abdomen perfectly smooth.

The head spines are peculiar; they are of fair size, but the two rear temporal horns are quite the size of the central (occipital) horns.

Length of Head and Body . . . . . 2 3/4 inches.
