Pearson-1990 22 Buneomys November 27- Refugio Frey-Laguna Toncek. At the west end of the lake on the south side of the valley, and along the south side of the lake, is a marshy-grassy habitat with runways and burrows exactly as Michael Christie described for the habitat of Buneomys mordax at Copahue. We found a few old droppings and some old cuttings of the low bush that grows there, but nothing fresh. Some of the runways were probably made under the snow. Five steel traps, 10 Shermans, and 8 Museum Specials overnight caught nothing. Some of the burrows were big enough to put your hand in and would be easy to excavate. The droppings are pale, blunt at both ends, coarse vegetable material; typical "Rice Crispies" of Buneomys. Lengths of a sample were: Length Frequency 7mm 6 8 0 9 4 10 3 Certainly seems to be Buneomys and probably B. mordax as at Copahue.
