Maynew 1961 Journal 42. June 7 5 mi. W. of Glamis, Imperial Co., Calif. the air temp (30") was 36.2°C. and the black-top at the edge of the pavement was 61.0°C. Three Callisaurus draconoides were seen on the black-top between 1455 and 1500. At 1545 a Phrynosoma m'calli was seen on the road. at that time the air temp. (30") was 36.4°C., the temp. of the black-top was 52.5°C. The animal was quite active and it escaped when a large gravel truck passed close by. However, 3 live P. m'calli were captured during the afternoon, & 4 dead ones were seen on the road. Two of these were in good enough condition to be saved. Steve & Walt looked for Uma notate in the dunes from 1645 until sundown (1800). They were able to capture about 20, most of which were young ones, for growth data. We began night collecting at 1950. We made one round trip from the top of the big dune to Glamis, through to the Highline Canal, back to Glamis, then to the top of the big dune (2.8 miles). This took us until 2235, and during this time we caught 22 Coleonyx variegatus & 1 Chionactis occipitalis (saw 2 Chionactis DOR). We found them (Coleonyx) considerably more abundant this month than last. We drove 136 miles today.
