18 February 1972 Peter, L. Petexbatun, Guatemala out. Occasionally large fish jumped (tarpon?). Many low fan palms & other palms. Bananas, coconuts, arbuzas (?). 10$ l. seen new kayafche). Dug in litter, old logs, from trees, looking for calamander, just so much. Only one boy seen old dog, under house (collected). Evening - heard many chocoboros. Set up nets dry lake shore. Took large Antilena between 10 pm & sunrise, but no other. Yet, dwellers in house say many saw same evenings. Looked around farther for 4 hrs. at night with light, but saw only one possum. Petexbatun, Peten, Guat. 19 February 1972. With Gail, we walked trail from house to W., to edge of swamp. Main tree was gnarled spreading "quinto", a very heavy wood, short & spreading, brownish and white in branches. In pulling apart an almpa, 15' up in tree, I dislodged an opossum. Wet inside plants, some snails, but I found no amphibs. I rolled logs, dug ground, pulled apart two plants, but found no vertebrates therein. | Paddled E. across lake into parts is- olated by growth of low spring (mosquito - like) bushes, and forked. Caught calavos, blancos (pistachio mouth). Gail said much better where lake shore. Cooler today. Put up one net in house clearing, other dry water. No catch in evening (only morning). Fog over lake in morni- ing; cool. Paddled N. to Don Alejandro's. Saw osprey. Left by canoe about 10 a.m. and arrived kayafche before noon. Again talked with Julio B., who thought Rio Celeste best place to find tegus. He also thought men more than females, or at least investigative | and more often taken. | We took bus about 2:15 for I-lanos, where we stopped and camped.
