Mayhew 1959 Journal 51. May 16 Mojave Desert, San Bernardino Co., Calif. after 1200. By 1400 we had captured 6 Cryptophytus collaris and 9 Sauromalus obesus, some in small rock piles within 50 yards of our campsite. Apparently the weather was so cool this morning that they hadn't emerged when we were scouring the rocky hillsides for them. In addition to these two species, we also collected at this site; for a total of 27 animals: Cnemidophorus tigris - 3 Uta stansburiana - 8 Callisaurus draconoides -1 After lunch (late) we drove back to the bench mark near which we had released 7 adult Cophosoma agassizi the afternoon before. Two of these animals (#12 and #14) were found about 50 feet south-east of the release point. None of the others were found, even though we walked about 1/4 mile in a south-easterly direction. We stopped looking at 1440. Other animals seen at this location wu: Black-throated sparrow Rock wren Masticophis flagellum Cotillus leucurus Scott oriole Yellow warbler While driving through the Ord Mts.,
