1983 17 January in diameter at 0.5m off ground. Belly yellow. (continued) As we walked W on the canal I caught an Andis lionotus that jumped into a large puddle on the way muddy trail. Reached Quebrada Cartasara and walked NNE until we reached the road we'd driven in on. Between the two I caught a fair sized Eleutherodactylus that has red thighs and light rusty dorsolateral stripes. By 1337 hr we were near a ridge top of wild cacao growing nearby. Again I noticed many earthworms under surface objects. Back to camp ~1420hr. Antonio Mora Rojas had cut more trail SW of camp today, and brought me andis, Eleutherodactylus, and an Oxybelis previnostius. With considerable prodding it inflated the anterior slightly and drew back the head and gaped, then slowly struck. Also kept the tongue extended at times when we photographed it. Cathy Pringle brought me a little secho found among rocks by the Q. Cartasara, which I catalogued as a Lepido- elepharis but might be a ? Sphaerodactylus. Michael Grayum brought me a Dendrophidion he found in forest near the big fall on the Quebrada. It tried to bite when he seized it. The snake is generally a velvety brown w/ slightly lighter crossbands when undisturbed.
