Two black bands on the neck with a white band inbetween them create the collar for which this lizard is named. The rear band has a wide gap on top of the back and is sometimes missing completely. The underside is mostly white. Activity: Active in daytime. Very tolerant of heat. Hibernates under rocks during cold temperatures in winter. Often seen basking conspicuously on top of rocks. May become bipedal when running quickly; raising up to run only on only the hind legs.

San Jacinto, south into Baja California Sur where it ranges as far south as just west of Loreto. https://californiaherps.com/lizards/pages/c.vestigium.html COMPARED TO Desert Collared Lizard (Crotaphytus bicinctores) that looks simiiar, but is found in Joshua Tree National Park and . . .
