Mayhew 1961 Sept. 16 Palm Springs, Riverside Co., Calif. Walt Moberly, Betty Aaron, Ed Eberle, Bill Truesdell & I left UCR at 0630. We looked for lizards from 0720 to 1400. No reptiles were seen along Varner Road from Garnet to 1000 Palma, except for a couple of young Uma inornata. Then we drove through Palm Springs Panorama to Vista Chino Drive. Walt & Betty worked near Vista Chino while Ed, Bill & I worked near Ranch Country Club. We found one Crotalus cerastes adult exposed on the surface in the shade of a can which rested in the shade of Dalea schottii. I stepped within a foot of it before I saw it. It never moved nor rattled, howerer, until we dragged it out into the open. This animal was seen at 1045 when the air temp.(36°) was 35.0°C., soil surface temp. at the spot where the snake was located was 32.0°C., at 1100 we found another Crotalus cerastes adult in the entrance to a burrow in the shade of Fritsneria dumosa. The first C. cerastes was 19½" long and had 6 rattles, the second was 18" long & had 10 rattles. The longer animal contained a Dipsodomya
