Seib, R. 1982 Tapachula, Chiapas, Mexico 21 Aug around again, it was fully dark. On this next pass, we heard some large Hyllid frogs calling from a roadside ditch. After a long time shining our flashlights into this tiny ditch, I finally spotted two of the beasts. They are mostly green above, white below, with a mottled pattern along the anterior side. About as large as half a fist. We made several more passes on the road, seeing 4 more of those frogs, but not a single snake. I am speechless at the fact that we saw not a snake. Not even a DOR, despite mild traffic. We did see a DOR Drymobius, however, which is a day snake. It rained tremendously most of the night. At certain points we would drive in first gear or stop altogether because the pavement would not be visible through the driving rain. We decided to drive back to Huixtla because I had stupidly allowed the gas gauge to fall below
