Mayhew 1962 Journal 51. Sept. 11 Dale Dry Lake, San Bernardino Co., Calif. dorsalis along Vista Chino. I looked for Uma from 1515 to 1530, and for Diposaurus from 1530 to 1600. I reached UCR at 1700 after a trip of 252 miles. There were very few tracks at any of these locations to indicate that many animals had been active there recently. Sept. 14 Glamis, Imperial Co., Calif. Howard Yorke, Valerie Ernst, Susan Larisch & I left UCR at 1650 for the September collecting trip. We reached the Highline Canal at 2100 and immediately began to look for Colonyx variegatus along the road. None were seen, however, on the first pass, so we stopped for the night on the big dune at 2130. The minimum temp. tonight was 76° F. Sept. 15 We arose at 0600 and ate breakfast. Then we drove the road between the two canals, looking for Phrynosoma m'calli, from 0715 to 0940. Three live and 2 DOR's were all that were seen during this period. Lizards were very scarce along the road this morning - we saw only 1 immature Diposaurus dorsalis, 2 juvenile Uma notata,
