R. Zweifel 302 Sceloporus occidentalis literatus Aug. 15, 1951 10 1/2 mi. SBE Julian, San Diego Co., Calif. These lizards were very abundant in an area of chaparral which was burned over about five years ago. The plants (mangosta, scrub oak, Cerocitrus and mountain mahogany in particular) have regrown from the base and form dense thickets from one foot to three or four feet high. In another thicket four feet out of the thicket protrude the dead stems killed by the fire. These dead branches provide the lizards with innumerable sunning sites. At my approach, the lizards either ran down the branch into the cover of the new growth, or dropped directly to the ground (a distance of 3 to 5') and ran to shelter. It seems that the fire has, temporarily at least, provided the scelopus with better living conditions than would prevail in dense, unburned chaparral where sunning sites are limited to boulders, or to road- brakes.
