K Dixon 1951 Holbrookia Apr. 17 Barton Cr., 4 mi. SW Austin, 500 ft., Travis Co., Texas Partial overcast obscuring sun - warm after 10:30; lizards active after that time. After 11:00 am I walked along dry, boulder-strown streamcourse. The clay-like crust had dried and cracked forming plates 4-6 inches in diameter. I flushed one Holbrookia from a brush pile at the edge of the streambottom after it had taken refuge there. It ran to a ±12" rock & crawled beneath it. I was able to capture it by hand by raising the rock. I wounded another which sought refuge under a rock ±12" across. When I lifted the rock, the lizard ran about 20 ft to another rock & took refuge there. When I lifted the rock it ran to another ±10 ft away; when caught there it returned to the first rock. The sequence was repeated before the lizard ran to a smaller rock to the W where I captured it. [illegible] (written from memory May 10)
