D. A. Good 1987 Journal Volcán Cacao, Prov. Guanacaste, Costa Rica 25 August (Centrolabell a few nights ago) With the intent of scoping the area out in daylight before returning for more night work. We cut a rough trail along the stream for this purpose. In the course of this work, we knocked a small Bothrops out of a bush (see catalogue), a rattler I knocked it out of a bush I didn't know it was in after CF had walked by the same track without seeing it. Also collected a Centrolabell tadpole. Back to Caco Mengo in time for supper. Then we walked down to the 980 m pond along the trail toward Finca Harold. Collected 7 Pana "pyrenis", several Pana tadpoles, a large mumble & mimohyliid tadpole + saw one Bufo marinus which we didn't collect. Also collected a Hylus sufronulus + a large Bothrops lateralis in the forest at just over 1000 ma elev. Bothrops lateralis seems to be the commonest snake around here - it's a bit unnerving finding them in the bushes all over the place - makes you wonder how many you've brushed by without knowing it. Weather windy + rainy in early morning - actually reasonably still (I'd forgotten what it was like) and fairly sunny in late afternoon. Pleasant evening in the woods, though a bit windy in the open pasture. 26 August Spent the morning again preserving, etc., specimens, then loafing until lunch since there wasn't time to do much (it was raining pretty hard + blowing strongly anyway). Ford weather right through the day, only ameliorating at dusk. We therefore didn't feel much like going out until then. At dusk we hiked up to the trail we had
