Mayhew 1962 Journal 36. July 19 Glamis area, Imperial Co., Calif. Walt Molerby, Fritz Zaebat, Dave Reuther & I left UCR at 0900 for our monthly collecting trip. We drove along Vauner Road (between 1000 Palma & Garnet) looking for lizards on the way down to Glamis. We looked for animals along this road from 1000 to 1200. We stayed beside the Highline Canal until the soil surface temp. dropped to 45°C. Then we looked for lizards along the road from 1510 to 1710. Then we walked in the dunes, looking for Uma notata & Urosaurus graciosa until sun- down (1850). After we ate, we drove the road looking for Colonyx variegatus. The weather was just about ideal for night collecting, but we found only 2 animals. We drove the road from 1955 to 2120. Maximum temp. today was only 103°F., minimum temp. tonight was 80°F. Today 4 juvenile Callisaurus draconides were seen along the road, as well as one juvenile Uma notata. July 20 We arose at 0520 & ate breakfast. We began looking for lizards along the road at 0625. We made 3 passes between the canals without seeing very many lizards. We caught only 5 Phrynosoma m'calli, 1 Diposaurus dorsalis & a couple of Crestophytus wislizeni. We quit looking
