Cogswell 1949 Sceloporus gracilisus Sep. 1 Brannon Mtn., 3957 ft. Humboldt Co. Calif. one 3:00 p.m. was collected here from a pile of boards & shingles, which is all that is left of an old lookout building. The mtn is on the highest part of the peak, in an open area with low boulders, grass & dry herbs, and surrounded by arctostaphylos shrubs (3 sp.) and open pine forests. The Temperature was estimated to be about 80-85° F. when two lizards were first seen here -- running between sections of the board pile when I back the truck over ground nearby. The one collected had re- mained in the shade of a board for 30 seconds or so, after having been chased for several seconds. It bobbed upward on its legs several times after arriving in the shade. Sceloporus sp. were seen along the road at abundantly various points within the open pine forest at higher altitudes here and also in drier ogh-madrone or exposed ridges & chaparral areas below the main Douglas fir belt; but the latter were probably S. occidentalis. Sep. 3 many noted in this same area, including some -4 very small individuals. Sep 6-10 Red mtn ridge, 5300-5400 ft. 14 mi. S Wayford Trmity Co. Calif. - This sp. is abundant in the more open shrubland and "chaparral", in open pine forest, and in the barren rock areas where any large rocks are nearby. I collected on 10th
