J. Rudger - 1942 49 Eumeces skiltonianus Oct 18 (cnt) Bald Rock, San Pablo Ridge, Contra Costa Co, Calif. over by hand; the others were under rocks that [illegible] out with a pick. Since we have hunted here by hand several times before, it may be that those rocks that were loose enough to turn over, had been turned over before or were too small or round. None of the specimens were deeper than under the surface rock & none of the rocks were more than 10" or 12" thick. Nov 11. [Rept of trip Nov 8] Mrs Vert Zoell, Univ Calif, Berkeley, Calif. Sunday morning, Nov 8, Frank Charles Libbey and I went to San Pablo Ridge, about 400 yards north of Bald Rock, to collect skinks. This was the first trip for this purpose since Oct 18, and the first since our first heavy rains. The ground is now moist, new grass is coming up, last year's grass is pretty well broken down, and what we to form a dense "undergrowth" is now matted down against the ground. Without speculating as to whether or not skinks in these hills "estivate" during the summer months, I would like to point out that the cover is much more restricted to rocks and underground holes and burrows now than it has been throughout the summer months, and that that might account for our finding more skinks at this time than any time since last spring.
