Mayhew 1959 Journal 35. April 14 Mojave Desert, San Bernardino Co., Calif. collecting site a mile west of Phelan. We walked this spot at 1130. We drove north on Beekley Road looking for lizards. We found several Sceloporus occidentalis and 1 Sceloporus magister. However, we expected to see more S. magister than this, so we drove west on Phelan Road to Highway 138, then west until we were 4 miles west of the Los Angeles Co. line (5 miles west of Desert Springs) and 6 miles East of Llano, L.A. County. The Joshua tree stand was larger and denser than the original site a few miles east. We caught 2 S. magister as well as a couple more S. occidentalis. There is a difference of about 600 feet elevation between these two sites (the L.A. Co. site is lower). We returned to UCR at 1635 after a trip of 119 miles. In all, 3 Sceloporus magister, 1 Phrynosoma coronatum, and 7 Sceloporus occidentalis were caught. Also seen in the Joshua tree area were Callisaurus draconoides, Crotaphytus wislizeni, & Uta stansburiana. April 18 Deep Canyon Desert Research Station, Riverside Co., Calif.
