Mayhew 1960 Journal 3. Jan. 29 Glamis area, Imperial Co., Calif. Then we drove through Desert Center to Blythe, and then to Glamis. (The air Temp. (30") at Blythe (1535) was 23.0°C.) We reached Glamis at 1730. After eating supper, we tried to night collect between the two canals, but didn't see a thing. The driving took place between 2000 and 2100. We went to bed on Dune Crest at 2400. We drove 194 miles today. Maximum temp. today was 65°F., minimum temp. tonight was 52°F. (11°C.). Jan. 30 We arose at 0800 and ate breakfast. Quite a few Uma notata tracks were visible on the sand, but nearly all of them had been made by very young animals. We looked for lizards from 1000 to 1245. The first Uma was seen at 1005 (juvenal). At that time the air temp. (30") was 18.0°C.; at 1cm it was 18.8°. soil surface temp. was 20.0°C. This animal was not captured. During the 2 3/4 hour period we saw 24 animals and captured 8 of them. However, all but one of the 24 were juvenals. The other animal appeared to be about 1/2 grown. Closeal temp. was obtained and the animals were released. No adults or their tracks were seen. Helianthus tephrodes (formerly riviers) was still in bloom in some areas. Frank dissected a sand hummock to see
