Mayhew 1959 July 16 Box Springs Mts., Riverside Co., Calif. This morning at 0525 Frank Aubrey & I left UCR for this collecting area. We saw our first lizard at 0540 (Sceloporus occidentalis), but couldn't catch it because it was behind a fence that was posted. However, we cought 2 Sceloporus orcutti before 0600 (0555 & 0559). In all, we caught 20 animals today, as follows: Sceloporus orcutti - 13 (7 ad. ?, 5 ad. ♀, 1 imm. ?) Sceloporus occidentalis - 4 (2 ad. ?, 1 ad. ♀, 1 ?) Uta stansburiana - 3 (2 ad. ♂, 1 ad. ♀) Sceloporus occidentalis were noticeable today by their absence or near absence on the mountains. Half of those we cought were seen while we were on our way home. Sceloporus orcutti didn't seem to be nearly as numerous today as we have seen them at other times, even though we were in the area at the time they began to emerge. We quit at 1205 and returned to UCR by 1215 after a trip of 31 miles. July 20 5 mi. N.W. of 1000 Palms, Riverside Co., Calif. Frank Aubrey & I left UCR at 0310 on our monthly collecting trip. We reached this collecting site at 0530 (after an hour's delay in Beaumont to get the brakes adjusted on #325). Frank got the soil sample at this station
