Journal Mayhew 1962 Aug. 4 Glamis area, Imperial Co., Calif. Crotaphytus wislizeni, 1 adult Uma notata (0), 6 Dipsosaurus dorsalis (1 ad, 5 imm.), and 12 Phrynosoma m'calli (4 ad or, 5 ad ?, 3 juv.) plus 3 DOR P. m'calli. Lots of juvenile Callisaurus draconoides and 2 juvenil Uma notata were seen. We rested under the bridge across the Coachella Canal until 1620. Then we went into the dunes 3 miles west of Glamis. At this spot there are lots of Palo Verde + [illegible] associated plants (Prosopis juliflora, Larrea divaricata). We looked for lizards until 1810. Several Uma notata were seen when we first started into the area, but few were seen when we got into the relatively thick palo verde. One Urosaurus graciosa was seen in a Prosopis juliflora, and 2 were seen in Cercidium floridum, but no others were seen. We caught 1 Urosaurus and 9 Uma while we were out there. It does not seem to contain very large numbers of lizards. The maximum temp. today was 103°F, which is very comfortable out here at this time of year. We looked for Coleonyx variegatus along the road from 1900 to 2315. One Urosaurus was seen on the pavement in the dunes at 1905. A juvenile Chionactis occipitalis was seen
