Sceloporus merriami, commonly known as the canyon lizard, is a species of lizard in the family Phrynosomatidae. The species is native to the south-western United States and northern Mexico.[1][2]
Etymology
[edit]The specific name, merriami, is in honor of American zoologist Clinton Hart Merriam.[2][3][4]
Geographic range
[edit]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,[1] and Nuevo León.[2]
Description
[edit]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.[5]
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.[6]

[edit]The seven recognized subspecies of S. merriami, including the nominotypical subspecies, are:[2]
- Sceloporus merriami annulatus H.M. Smith, 1937 – Big Bend canyon lizard
- Sceloporus merriami australis K.L. Williams, H.M. Smith & Chrapliwy, 1960 – southeastern canyon lizard
- Sceloporus merriami ballingeri Lemos-Espinal, H.M. Smith, Auth & Chiszar, 2001 – Ballinger's canyon lizard[4]
