Mayhew 1962 Journal 37. July 20 Glamis area, Imperial Co., Calif. along the road at 1000. During the drive we saw 1 DOR Phrynosoma m'calli and 18 juvenile Callisaurus draconoides. We rested under the Coachella Canal bridge until 1630 , then returned to the dunes for Urae and Urosaurus. We looked for lizards until shortly after sundown (sundown 1845; we quit 1855). After eating chow, we night collected from 1935 to 2200. Colonyx variegatus were somewhat more numerous on the road tonight than last night. However, the temperature is somewhat higher, and so is the humidity! We caught 5 Colonyx tonight, including a young one. The minimum temp. tonight was $86^\circ F$. We were chared off the big dune (Osborne Park) about 0030 by the wind + sand. July 21 We arose at 0615 and ate breakfast. Then we drove the road between the canals looking for lizards from 0655 to 1125. We saw 5 DOR Phrynosoma m'calli and lots of DOR Callisaurus draconoides juveniles. The sky was completely overcast all morning, with no breeze blowing. Consequently, the humidity was rather unbearable. However, 6 Phrynosoma m'calli were captured during the morning.
