Mayhew 1964 Journal 5. July 2 UCR campus, Riverside Co., Calif. The University finally accepted our outdoor lizard observation cages in the botanical garden today. We had lizards in the cages within 5 minutes of the time the inspector told us he would accept it. Aug. 3 Palm Springs, Riverside Co., Calif. al Bennett, Ken Evans & I left UCR at 0720 to collect some lizards to use in the new outdoor cage (hereafter called ROC, for reptile observation cage). We captured 13 immature lizards that we measured & released. We also captured 5 Uma inornata, 8 Dipsosaurus dorsalis, 1 Callisaurus draconoides, & 1 Phrynosoma m'calli that we brought back to UCR. In addition, we recorded the time that 46 lizards were active. Later we measured the temperature of 2 Dipsosaurus dorsalis continuously (Yellow Springs telethermometers) after they were released into their burrows. We measured the temperature of one for 20 minutes, the second one for 43 minutes. We returned to UCR at 1515 after a trip of 143 miles. Aug. 18 Mojave Desert, San Bernardino Co., Calif. al Bennett, Ken Evans and I left UCR at 0610 to try to get lizards to fill some "holes" in my data.
