Mayhew 1958 Oct. 17 10 mi. E. of Newberry, San Bernardino Co., Calif. Journal 109. When we left Newberry, we traveled east to the lava beds produced by Piagah Crater. We reached there about 1125. We caught a total of 8 lizards here: 1 Phrynosoma platyrhinos, 1 Uma scoparia, 1 Cnemidophorus tigris, 4 Uta stansburiana, & 1 Urosaurus graciosus. The air temp. upon our arrival was 32.2°C., the soil surface temp. was 47.8°C. Nearly all the animals were catched on the sand between the lava outcrops, but a couple of Uta were caught on the lava. For the amount of territory we covered, we saw relatively few reptiles. We left the area at 1245 when the air temp. was 36°C., & the soil surface temp. was 48.5°C. 6 mi. S. of Barstow, San Bernardino Co., Calif. We stopped at the Stoddard Well Road and walked around the area from 1445 to 1530. Although the area had received heavy rains this summer (judging from the newly washed gullies), and the creosote bushes were in fine shape (some are setting seeds now), not a reptile was seen the entire time. Temps. when we left were: air - 32.4°C., soil surface - 34.2°C. One Uta stansburiana was caught a little later (1645) five miles further south. By this time the sun was nearly ready to set. We drove through Lucerne Valley, Hesperia,
