Hanken, James 1975 Journal Mexico trip 8 May 1200 hrs trip. (cont'd) Continuing W on Hwy 80 we stopped at 6.7 mi E of Ciudad del May after Sam spotted a Sceloporus basking on a rock alongside the road. This turned out to be the best locality yet encountered. The area comprises a slightly rolling former lava field overlooking the Central Plateau to the W. There are several low (1-2' high) outcrops of basalt alongside the road. Much of the area is used for agriculture and here the cleared rocks have been arranged in fence rows 2-5' high. The lower-lying uncleared areas have scattered yucca to short yuccas and low shrubs. In addition there is an oak-dominated forest (at least 3 sp.) of tall scattered oaks and little understory cover. In all, four species of Sceloporus, one sp. of Cnemidophorus, and one sp. of Scincella were found. The Cnemidophorus (2 by Sam, 1 by Allen) were found in the low yucca + shrub area. Philip Green found the Scincella in the leaf litter beneath a fallen log adjacent to the oak woodland. The Sceloporus may be broken down into two types, large & small, with two species in each type. The smaller species consisted of S. variabilis found mostly on trees + boulders in the oak forest
