Mayhew 1962 June 12 Journal 26. Colorado Desert, San Diego & Imperial Co., Calif. Hot Springs & Earthquake Valley to the Coyote Mts. (near Coyote Wells, Imperial Co., Calif.), I had heard about Phyllodactylus tuberculosis being collected in these hills, but we couldn't find any sites that even looked promising. Therefore, we drove to Highway 80, then west toward Jacumba. We pried flakes off rocks for some time, but found no animals. Then we drove Highway 98 toward Calexico, looking for animals as we went. Two Diposaurus were all we cought, or even saw. We then drove east of Calexico on highway 98, looking for Phrynosoma m'calli. The weather was favorable, but no animals were seen. We drove to the Highline Canal west of Slawis & ate dinner. Then we began night collecting along the road between the canals. We collected from 1935 to 2240. Coleonyx were on the road early in the evening, but the weather was rather cool, so none were seen after 2200. We saw 3 Crotalus cerastes during this period, as well as 1 DOR Phrynosoma m'calli. Several Lepus californicus were seen along the road as well.
