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. 



Family IX. SCINCID.E. 



The tongue is slightly notched at its tip. The head 

 is covered with large, regular plates. The scales on the 

 body and tail are moderately large, imbricate, and rein- 

 forced with an armor of bony plates. The eyes have 

 round pupils and well developed lids. Femoral pores 

 are absent. Limbs may be either present or absent. An 

 interoccipital plate is rarely present. 



A single genus represents this family in California.
