D.A. Good 1987 Journal Ublein (Cacao) Proy. Guanacaste, Costa Rica Nototriton (probably) eggs (in moss on vertical trunk ca. 3½ feet off ground. Moss temp 17.4°C, air 17.1°C). These eggs are much less developed than the previous set had been, but from within 10m of it. Back to Casa Mergo mid-afternoon + spent the rest of the day cleaning up, etc. 31 August Did nothing except catalogue a few specimens + write field notes during daylight hours today (our enthusiasm for working here is definitely decreasing - the fact that we're leaving in a couple of days probably has a lot to do with it). Did some laundry. At dusk we headed up to the Centridella stream past the summit of the trail to Casa Frankin Lopez's finding some more Centridella. On the way up the trail we collected an Echis barbouri or vegetation and a Bothrops schlegelii. The Bothrops was hanging upside down along a sapling beside a large fallen log - very cryptic. It was positioned in strike position with its head a few inches above the ground obviously waiting for something to come running along the edge of the bog. I have never seen a place with more poisonous snakes - Bothrops (lateralis + schlegelii) taken together equal 2× the number of all other snake species combined! The only specimens collected along the stream were 2 Centridella prosilepon calling from vegetation on a dirt/sand bank ca. 12 ft above the stream. I managed to climb up high enough to get one using a sapling growing out of the bank. On climbing back
