Mayhew 1961 Mar. 20 Journal 15. UCR campus, Riverside Co., Calif. This afternoon Walt Moberly & I looked for lizards on campus. We began at 1330. At that time the weather conditions were: air temp.(30")-23.8°C. (1cm)-27.0°C. soil surface temp.-43.6°C, rock surface temp. - 42.8°C, 0-3 mph wind from N.E., 50% overcast (thin). We looked for Sceloporus orcutti from 1330 to 1430. Only 4 animals of this species were seen (1 ad. ♀, 3 juveniles), 3 of which were captured (ad♀ & 2 juveniles). at 1430 we left the rocky area & started looking for Crepidophorus hyperythus several hundred yards east of Welber Hall. Only one animal of this species was seen (about 1500), and it eluded capture. However, 7 Uta stansburiana (5 ♂, 2 ♀) and 1 Sceloporus occidentalis were captured before we quit looking at 1530. One Eumeces skiltonianus was seen while we were looking for Sceloporus orcutti. At 1530 the weather conditions were: air temp.(30")-22.2°C. (1cm)-24.5°C.soil temp.-33.0°C. wind 5-8 mph from NE, 75% overcast (thin). We looked in locations where numerous S. orcutti & C. hyperythus were seen earlier this year, so I feel quite certain they simply weren't active at this time of day today. Numerous Uta stansburiana were seen, but relatively few Sceloporus occidentalis.
