Mayhew 1964 Journal 3. June 3 Glamis area, Imperial Co., Calif. Two live P. m'calli that I had used for an experiment were released 11 miles west of Glamis. They were toe-clipped # 112 (0?) and # 128 (?). Thus, 40 P. m'calli have been released thus far in 1964(3 in 1962). We made only one pass between the canals at this time (to 1200). However, we looked for P. m'calli again from 1540 to 1700. We found 1 additional DOR P. m'calli, but no live ones. At 1700 we drove to the dunes to get a collection of Uma notata and Urosaurus graciosus. We captured them between 1700 and 1815. Then we collected Colonyx variegatus between Glamis and the Highline Canal - along the Ben Hulse Highway (Imperial Co. S 78; Brawley-Blythe Highway) from 1930 to 2205. We captured 9 during the evening. June 4 We looked for P. m'calli between the canals from 0700 to 1030. During this period we caught an adult Arizona elegans on the road 8 miles west of Glamis (at 0705). We caught 7 live P. m'calli during this interval. In the meantime Shirley Hill donated 2 P. m'calli to the cause that she had captured the previous day.
