Hanken, James 1977 Journal Green Turtle Station, Tortuguero, Costa Rica 30 Aug The weather has changed in the last few days, with rain falling off+on throughout the morning and early afternoon, usually clearing by late afternoon. Steve Carr and I visited a small cave or at the base of the SE face of Cerro Tortuguero on 27 Aug. Earlier this summer a cross group had found two Lepidophyma, three species of bats, a Botrops, and primary bones in the cave. It is a small cave, actually a small void into otherwise solid vertical rock face at the base of the mountain. The opening is ~5'x5' and the chamber extends only ~6' in with a ceiling ~9-10' high. Crevices taper off in various directions from the chamber. There were ~15 bats hanging from the ceiling. Efforts to collect them were unsuccessful as they quickly flew at our approach and couldn't be caught with a hand net. However they could be easily mist-netted. We saw another Lepidophyma and a few Eleutherodactylus (25-30 mm.SVL). I took one of the latter as it looked different from those commonly found in the forest because of its thin, white vertebral stripe. I put out a mist net between two coconut trees next
