Aiguafel 297 May 6, 1951 Cnemidophorus stintonensis Swi WSW Fairfax, Marin Co., Calif. Grassy hillsider with madrone, live oak, and bay in the draws. Intermittently cloudy and sunny. Spent about 15 minutes turning over rocks but found no lizards. The soil beneath the rocks was moist, but not excessively wet. While walking along the shoulder of the road I saw a small skink rush off into the brush and escape. By walking quietly along the shoulder and checking on every small move heard, I was able to catch three skinks, positively identify three more, and see four others which were probably skinks. Cnemidophorus coenula and Sceloporus were also present. Two of the skinks which escaped did so into rodent holes. Another entered a skink-project hole between rocks. I returned about 15 minutes later and catched a skink (the same one?) at the mouth of the hole. Body temperatures of 24.0°C and 28.8°C were taken on active skinks. The air was about 16°C.
