Mayhew 1959 Journal 68. June 23 Mojave Desert, San Bernardino Co., Calif. This morning at 0700 Frank Aubrey, David Reuther & I left UCR for the Phelan area. We reached the collecting area at 0800 and immediately began to capture Sceloporus occidentalis. As usual, Sceloporus magister were very hard to locate. We have found that we see more lizards in this area by driving along the dirt & paved roads than by walking. Therefore, we drove over many of the roads in this area between 0815 and 1400 when we stopped looking for animals. By that time the wind was blowing so hard we couldn't control our nooses. We found Sceloporus occidentalis from 0800 to 1040, and again from 1310 to 1400. Sceloporus magister, on the other hand, was seen from 0900 to 1215 and that was all. There was no second activity period while we were still there. A total of 28 animals were caught today, as follows: Sceloporus occidentalis - 21 (14 ad. M, 5 ad. F, 2 ad (?) ?) Sceloporus magister - 6 (1 ad. O, 2 ad. F, 2 ad (?) ?, 1 ad (?) ?) Crotaphytus wyaligani - 1 (ad. O) We reached UCR at 1510 after a trip of 133 miles today. June 24 3 mi.
