Seib, R. 1984 Tapachula, Chiapas, México 31 Oct. more Nivia, as always, but also a large Drymarchon corais, a Saphiodontophis annulatus zeteki, and a couple of Xenodon rhabdolephalus. They brought me a 77.0 gram Micrurus nigricans that regurgitated an 11.0 gram Ameiva sp. We set up a 30' and 18' net in the clearing where we had good success before. Unfortunately, the half moon was very bright and although we netted from 1800-2300 we only got bats when it was dusk or when the moon was covered by a cloud (not often). We got 19 Sturming lilium, 2 Glossophaga, 2 Carollia, 3 Artibeus, and 1 Vampyrops helleri. Allison sampled the sturning, released it, and we drove back to Tapachula, arriving after midnight, passed out. 1 Nov. Today is our last full day in Tapachula. We drove out the Nueva Alemania Rd. looking for a good place to net bats, but the terrain is too badly cut over, and where there is high forest it just caves coffee trees, not fruit trees or Piper. We decided just to net at San Jeronimo again. They had few snakes, mostly Nivia,
