Hauken James 1978 Journal N slope of Cerro Pelon, Oaxaca, Mexico 8 July The Epiloboa was found by us beneath a rock beside the road at 65 Km N Guel we found one thorius (cloud) beneath a rock on a fallen log a few feet above the ground. We visited an additional locality below 65 km N Guel and above Vista Hermosa but found no thorius. Workable localities are hard to find because of the steep slopes, but even here, where access was possible, no animals were found despite our thorough search of several breliade and other available cover. At this point the rain, which had been pouring steadily for ~5 hours, became unbearable and we quit for the day and headed into Tuxtpec (including some successful night driving and a stop to collect from a breeding chorus of several frog species). This marks the end of the thorius part of the trip. Tuxtepec to Mexico City, Mexico 9-18 July Our last 4 days together were spent hitting additional Ambystoma localities, collecting successfully at Lake Alchichica Puebla, and near Lake Zempuala S of
