Pearson - 1993 19 Mariana Losada about her mouse behavior project. Then went up to the knoll of Cerro Otto south of the YPF gas station at the beginning of the Faldeo. This is the place where we caught a good xanthorhinus and an Eligmodontia, and only a few hundred yards from where we caught olivaceus in the Cerro Runge meadow; Altitudes were: Apartment 2790; car 2820, YPF Meadow 3110; the knoll on the flank of Cerro Otto 3440 (where the xantho was caught). Took black and white photo of the trap site: cipres, Colletia, maiten, green orchid, cardon (= Eryngium panicultum), Berberis, Rumex, very little bunchgrass or other grass, Nearby but not in the photo were Acaena, neneo, Adesmia, Mutisia. 13 December- Drizzle off and on all day, mixed with sun. At Ecotono saw a reprint: Rabassa, J., 1974. Geologia de la region de Pilcanihue-Comallo. Fundacion Brilocha, Dpto. de Recursos Naturales y Energia, Publ.No. 17, 128pp. Clara Bosch and Adrian came by, Clara with a note from Ricardo Ameijeiras about mice frozen in a glacier. 14 December - Bariloche. Clear, not windy. Drove out to km 6.7 to see Ricardo Ameijeiras. He had read about the mice frozen in the Esperanza glacier, but had no further information.

He had a young Chusquea colihue plant in his garden, which he had transplanted 1 1/2 years ago. Almost half of its culms were tall thin 1-yr- olds. At 5:30 drove down the Limay Valley to the first two caves up the Traful Valley. At the first little cave alongside the road at the first curve, we set 3 cage traps and 8 Shermans. There were mouse footprints on the sand in the cave and in the sand outside. Some traps within the cave, and some outside but only a few meters away. Also set 3 cage traps and 9 Shermans at the entrance and close to the entrance of Cueva Traful. At one set was a pile of cut stemswith blossoms of Colletia, in front of a hole under the cliff. Camped across the Traful River in the pine/cedar grove. Windy, overcast in the evening, but night clear. 15 December- Bariloche. Morning clear, sunny. The traps at the little cave by the road had one Abrothrix longipilis in a cage trap IN the cave. At Cueva Traful there was 1 big Phyllotis in a Sherman and 1 big Auliscomys in a cage trap. The Auliscomys was trap-
