J. Rodgers - 1940 Eumeces gilberti Dec. 4 Mrs. Vert. Zool, Univ. Calif., Berkeley, Alameda Co, Calif. the belly exposes light green scales with yellow centers. This soon turns bright green, then live green, then blue; eventually as dark as the back. An area freshly exposed, dried with a match turned to the dark blue within 30 seconds or less. Dec. 7. On the evening of Dec. 5 I put 15 oz 20 heaping teaspoons full of dirt into the tunnel. On the morning of Dec. 6 the entire entrance was closed. In the late afternoon (about 3:30) I noticed that there was a hole where a shed has stuck its head out but had not come out. At 5:30 the hole had been closed and the pile of dirt closing the entrance had been reinforced all along. This was evidently by force of shed skin that were sticking through the dirt along the top of the entrance. The skin was not showing at 3:30. The presence of the skin may (in fact probably) indicate that they are running short of dirt inside, and are having to scrape the floor rather thoroughly to get enough to close the entrance. The entrance of this tunnel consists of two holes [illegible] The tunnel is narrower at the back than at the front. I will either have to build the dirt up in front, or keep them supplied with dirt to plug the entrance with, because they push it out to open it, and it slides down an incline.
