Distribution. Belding's Orange-throated Lizard has 

 been found in California only in the western parts of 

 San Diego and Riverside Counties (San Diego, Mexican 

 border between Campo and the coast, Oak Grove, be- 

 tween Oceanside and San Jacinto, San Jacinto,*River- 

 side), but ranges for some distance down the peninsula 

 of Lower California. 



Habits. At San Jacinto this lizard lives on rocky 

 hillsides, is very shy, and quickly retreats to holes when 

 approached.
