Mayhew 1961 Journal 73. Sept. 11 Glamis area, Imperial Co., Calif. We caught 6 P. m'calli on this pass (1 ad ♀, 2 ad ? or 3 juv. ♀), as well as 1 juv. Uma notata, 1 ad or Uma notata, & 1 ad ♀ Uta stansburiana. We began night collecting at 19 00, & quit for the night at 21 00. We caught only 2 Colonyx variegatus (1 ad ♂, 1 ad ♀), maximum temp. today was 106°F; minimum temp. tonight was 80°F. We camped in a gravel pit 2 miles east of Glamis because the wind was blowing sand on top of the large dune where we usually camp. Sept. 12 We arose at 0630. We looked for lizards in the dunes from 0730 to 1030. Very few adult Uma notata were seen during this period. 3 ad or & 2 ad ♀ were caught. The remainder of this species caught this morning were immature and juvenil. 11 Urosaurus graciosa were captured during the same period. One baby Crotalus cerastes was seen and the tracks of another juvenil were observed this morning. The middle of the day was spent in the Glamis store and exploring the dry lake-bed on the east side of the dunes about 6 miles north of Glamis. Grass
