Salamanders were on the vertical walls as well as the horizontal ledges. The salamanders appeared very pale in the cave but considerably darker when we were pickling them later. The other part of the sink hole is a vertical short horizontal shaft off an antechamber. I collected a (#53) large Chiroptero triton (and a mass of eggs) at (54) The vertical wall of the antechamber. The eggs were on a slightly sloping shelf off the vertical t were strung out in a string oval in shape: [illegible] The salamander near the eggs moved slowly toward a crack. She was first seen just a few mm. away from the eggs -- not touching them. Sam saw two more Chiroptero triton in the cylindrical vertical shaft off the antechamber of this second part of the cave. Left Ahuacatlan and drove east on Hwy 120 through Xilitla and above a very large laranca to Mex. Hwy 85. Took this way north to Ciudad Valles & checked in at the Hotel Valles. Had dinner w the restaurant and then pickled the days catch. Sam made a couple of forays through the hotel for Gebyra mutilata and got several. The place is what you could easily call "infested" with teen geckos. I'm bed about 1 AM.
