Etymology

The specific name, merriami, is in honor of American zoologist Clinton Hart Merriam.

Geographic range

It is found in the United States in the state of Texas, and it is found in Mexico in the states of Coahuila, Durango, and Chihuahua.

Description

Adults may reach 58 mm (2.2 in) snout to vent length. 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.
