Shot an adult Ameiva as it crawled about in a smut weed patch by the roadside at about 4000'.

These Hyla wherever found seem to be restricted to watercourses and their vicinity. Noticed no tadpoles here, as the stream is quite a bit more rocky than above, and consequently there are fewer pools. In the early P.M. went down the west slope. In a coffee grove west of camp, at about 4300', I took my first specimen of Sceloporus malachitus. I saw it on top of a large, well shaded, fallen log beneath the coffee bushes.
