Greene, H. 1988 5 January (continued) frogs calling, but I saw no gralbes. The moon is more or less full, and the forest is well lit anywhere there's a hole in the canopy. 6 January Spent most of the morning packing - leaving La Selva today for San Jose and the U.S. A beautiful ride out - bright blue skies, white clouds, and the green slopes well lit in the afternoon sun. 8 January Carmen got my export permit this morning without problems. I went to the Instituto Clodomiro Picado with Alejandro Solorzano, where he gave me 2 very Bothrops nummifer, born in captivity, a gold B. schlegelii from the Pacific slopes, and a peach-colored B. schlegelii that only reached the institute today from south of Heron. Alejandro told me that B. labialis is the snappiest arboreal viper here, and as he was telling me that the one I was looking at on a book made a fast strike at my face that ended with a "flash gape" for an instant. Photographed an Enulius from near the institute. In the afternoon I talked with Federico Bolanos, who gave me a scat or stomach content of a B. schlegelisi (59.6 cm, 122 g, UCR 10231), Finca La Palma, Dos Rio de Upala, Prov. Alajuela, 5 November 1987).
