P. PEARSON 1955 a little Tillandsia still at Chacria. Then drove to 3 mi. E Motuana, 8200, to sample and set traps. North facing slopes of narrow gorge are mild oats and scattered woody bushes 2 to 6 feet tall, at least 6 species. 5-facing slopes look more alto-plana with few bushes and some bunch grass. Set a bag of museum species (corn meal) among oats - bush plus some in some vine-covered stone ruins + First llanar camping at [illegible] (some at Arma spring) about 8500 feet. Not much cactus. Another short bag of museum specials at San Mateo, 9500 ft. Rather brushy, not unlike magister terrain in southern Peru. Brushier than the other line 1 mi. E Motuana and with fewer mild oats (more heavily grazed), [wood building camps] Aug. 11 The lower part of the 8200 ft. trap line in oats, scattered low shrubs, and rocks caught 1 Marmosa and 1 long-eared darwini-arduin (Rh from 1 mi. W Motuana had simple ears too). The longer upper part of the line in oats, low weeds "sage", caught nothing. The 9500 ft. line in brushy places caught caught 1 Akodon, 1 long-tailed Oryzomys, 7 R. arduin Skinned til noon then went downhill to set traps. About a dozen at the Zuniga nut place (1 mi. E San Bartolome', 4800 ft), 5 of them with more meat bait. Then set a bag of museum specials (corn meal) at 4400 ft near a mine? right by the road.
