Packed up and started back down July 85. Last night's camp site was, therefore, the furthest south we penetrated on this trip. Took a couple of photos of the cultivated mountain tops in the vicinity of Cuesta Colorado, Hidalgo which is just below Puerto de la Zorra. Found a badly flattened Dorz swathe ([illegible]) on July 85 0.9 mile SW of the Hidalgo-San Luis Potosi line in Hidalgo; near Cantil de la Gringa. Gassed up & cooled up at Tamazunchale and then headed north again. Checked several sites along the road that looked like they might be good Anelyropsis habitat, i.e., shaded areas beneath trees with leaf litter -- there were generally orange & mango groves. At one site -- El Laurel, San Luis Potosi Sam caught two Anolis while sating the leaf litter at the buttresses of large trees. Continued north to Cusack Valles & pulled in for the night at the Hotel Valles where Sam caught several more Gehyra mutilata.
