Gulloni 1949 Sceloporus gracilous -1- Sept 1 1 mi W Brannan Mtn., 3300 ft, Humboldt Co., Calif. Taken about 2:15 p.m. under a scrubby Tan Oak on the edge of an acre clearing covered with Ceanothus cuneatus. The animal had been foraging in oak leaf litter in full hot sun and ran for shelter as I approached. This area is on the edge of extensive logging operations in Douglas Fir Forest. Later, I was seen and later collected (by Cogswell) on the top of Brannan Mtn 3900 ft. (see Cogwells account). Sept 9 Red Mtn., 5300 ft., 14 mi S Hayford Trinity Co, Calif.- I collected on a S facing slope covered with widely (10 feet apart) spaced Ceanothus cuneatus bushes. The area between the bushes, and where this lizard was foraging, is composed of 1/2 to 3 inch broken fragments of a shiny Serpentine like rock. This area has been in full sunlight for probably 3 hours. The temperature in the sun where this animal was foraging is 89° F. -A second one collected on a black-lichen covered rock out-crop on the crest of the ridge. At the time of collecting the sun was behind a cloud and the light breeze gave a temperature of 70° F. The sun came out and the temperature went up immediately to 73° F.
