The 20-25 traps in 2 different/ bare pin forests caught nothing. Showing them and constructing an age pyramid. C.J. Ralph reports that the forest on the small side of Cauro Otto is larger. He found a dead Motornyp with crushed shell: weight 47g, hind foot 24, tail 44 near the top = the middle-sized Motornyp x = cholamys mar. 17 Drove out to the hollow lake of Estorin Perito Moreno on the Picoanuel road, then climbed up to a cave at the base of a cliff nearby. Caught 4 gecko-like lizards under stones on the slop near the bottom of the cliff; lushy-stiff vegetation. 2 individuals under each stone. Then drove back to Cauro Famoso and picked up owl pellets, only about a quart and not many of them very recent. Saw 2 vizcacha there. Also picked up a few pellets of Perito Moreno, including Encooryps, drives christie's for mar. 18 Drove to Caudo Piedra on the Rio Colafu looking for the anthropologists Willie and Mary po Wergin. Pass de Cordoba goes directly from scrubby trees to large without Confluence. Camped along the Rio Colafu under some poplars on the south side of the river, about 2 km east of where Rio Meliguiva joins Rio Colafu; 28 km NW of Confluencia. This is only about X 1 km upstream from our collecting locality a couple of years ago. I laid out about 45 mouse traps and a couple of jump traps in nuevo - [illegible] desert with Collector Barberis bushes, including a few in rocky cliffs. Autos also laid out about 38 in Coleta - nuevo desert, 2/3 of them jump traps. Four freshly killed hare between Barcolos and Confluencia.
