1983 27 February (continued) then further up and into some nice forest on a very narrow trail. Trail reaches a dry aqueduct (?) ditch, then turns right and parallels it around the slope, climbing slightly and eventually reaching a stone dam and simple spillway gate. Found two Norops lionolus trapped in the spillway outlet, trying to swim upstream but unable to climb the sides when they paused. One I caught was a beautiful male, released upstream. By now ~1700h, so we made camp upstream ~150-200m, had dinner, and enjoyed the night. Raining on and off, but no frogs calling and no Helopus seen by day. 28 February Broke camp and explored some. At 0909hr found an Erythrolamprus vixonus resting in sun dappled leaf litter a few meters into the forest from the stream. Snake ~40cm TL. Beth saw it, and I grabbed tail as it dived into leaves. Throated and cloacal discharged, but didn't bite. Heard howler monkeys. Walked uphill on a ridge right of the stream (looking upstream), then walked back to car. It had been broken into: food gone and battery dead. Passerlyos helped push and we started it. Lunch in Liberia, back in San Jose ~1730h. Dinner w/ Manuel Santana.
