Mayhew 1959 Journal 34. Mar. 28 Deep Canyon region, Riverside Co., Calif. Ruibal left the rest of the group to go down a different ravine than the rest, he saw a group of seven bighorn. The last of the group reached Tevio's car at 1825. Lloyd took me back to Nightingale for our car, then I picked up the rest of the fellows in Palm Desert. We reached UCR at 2205. Mar. 31 2 mi. S. of UCR campus, Riverside Co., Calif. This morning Frank Aubrey and I went to our Sceloporus collecting site. We reached the area at 0930, and caught our first animal (Sceloporus occidentalis) at 0940. Several Sceloporus orecutti (both imm. and adult) were active at this time, but we were unable to catch any the entire morning. They were extremely wary today. However, we were able to catch 5 adult Sceloporus occidentalis (4 ?, 1 ?) and 3 Uta stansburiana (2 ?, 1 ?). Nothing seemed to be active by 1130 (particularly no S. orecutti), so we quit at 1140. S. orecutti seemed to be very abundant earlier in the morning, but I've never seen them as wary. April 14 Mojave Desert, San Bernardino Co., Calif. Frank Aubrey & I left UCR at 1030 and drove to our Sceloporus magister
