This species falls readily into the first group of the genus, by reason of its short horns and exposed ear drums. The scales of the abdomen are smooth, and the chin scales are small and regular with no enlarged rows. The enlarged scales of the back are but slightly bristling.
The horns are barely larger than those of Hernandez's Horned Lizard; the central horns are the larger and of about the same length as the horizontal diameter of the eye opening. As with Douglass's Horned Lizard and its varieties, there is a single row of spiny, marginal scales on the side of the body.
Length of Tail, Male, . . . . . 2 1/8 inches.
Greatest Width of Body . . . . . 1 5/8 inches.
Length of Central Horns . . . . . 1/8 inches.
The tail of the female is much shorter than that of the male.
