Mayhew 1959 Journal 79. July 29 Phelan area, San Bernardino Co., Calif. air temp. (30") - 23.7°C. " " (1cm) - 23.4°C. soil surface temp. - 21.0°C. wind - none relative humidity - 22% The first Sceloporus occidentalis was seen at 0650, also sitting in the sun on the trunk of a Joshua tree. We saw about 8 Sceloporus magister and 2 Sceloporus occidentalis before we were able to capture any lizards. Three newly hatched Uta stansburiana were seen in this region during the day. Sceloporus occidentalis were so numerous along the road 1 to 3 miles east of Phelan that it took us 3 hours to drive the 2 miles. We continued east of Phelan to Hesperia, then S.E. to the crossing over the Mojave River. We spent from 1330 to 1430 resting in the car by the bridge. Then we retraced our route looking for lizards again. We returned to Phelan, then drove N.W. from that village. Sundown occurred at 1850, so we stopped looking for lizards at 1900 and returned to UCR. We reached the campus at 2015, after a 172 mile trip. The animals caught today were as follows: Sceloporus magister - 8 (3 ad ?, 2 ad ?, 2 im ?, 1 im ?) Sceloporus occidentalis - 21 (9 ad ?, 11 ad ?, 1 im ?) Callisaurus draconoides - 1 (ad ?) Total = 30
