Etymology
The specific name, merriami, is in honor of American zoologist Clinton Hart Merriam.[1][2]
Geographic range
S. merriami is found in the United States in the state of Texas, and it is found in Mexico in the states of Chihuahua, Coahuila, Durango, and Nuevo León.[3]
Description
Adults of S. merriami may reach 58 mm (2.2 in) snout-to-vent length (SVL). Including the tail, they may reach 162 mm (6.4 in) in total length. The dorsal scales are small, and the lateral scales are granular.[4]
Dorsally, the canyon lizard is gray, tan, or reddish-brown, matching the rocks on which it lives. There are four rows of dark spots on the back, and a vertical black line in front of the front leg. Males have blue and black lines on the throat.[5]
