Mayhew 1959 Journal 92. Sept. 9 Glamis area, Imperial Co., Cal'f. On the drive down an adult Phrynosoma (sp?) ran across highway 99 in front of our car about 5 mi. w. of Westmoreland. This occurred at 1510 when the air temp (30") was 38.8°C, and the soil + road temps. were 55.0°C. We stopped the car, but could find no trace of the animal by that time. We reached the Crackella Canal near the Algodones Dunes at 1630. We began looking for lizards at 1650. A large number of recently hatched lizards were seen: Crotaphytus wislizeni - 1 Uma notata - 25 There were also a large number of adult animals active at this time of the evening. We captured the following before dark: Uma notata - 13 (3ad ♂; 6ad ♀; 2imm ♂; 2imm ♀) Callisaurus draconoides - 1 (ad ♀) We stopped looking for diurnal lizards at 1830 (sunset at 1755). We began night collecting along the road at 1900. However, night collective wasn't so good. We caught: Colubyx variegatus - 2 (ad ♂) Uma notata - 1 (ad ♂) We saw 3 newly hatched Crotalus cerastes between 1920 & 1930 within
