Mymal Leng 1969 journal 22 July 6 (cont.) Papa Leon Tree, (50+ ft.), Dept. Lima, Peru where we trapped the first night. The location is The area has many old ruins + some low rock walls or house outline. It is sandy with Tillandsia. We set out all 65 or so of the small Shermans and 40 of the large folding Shermans. There was no mouse sign, but is similar to areas where we have caught a few Phyllotis darwini + Mus musculus. Tomorrow we plan to tag and release any mice we catch there. Then we are going to the mountains around the Rimaco Valley for a couple of days. 32 mi. S Cuzcapalca, 14,700 ft., Dept. Lima, Peru July 7 We have driven up the Rimac Valley to an altitude of about 13,000 ft. We are about 2.5 mi. above Cuzcapalca by road. There are 3 basic habitats. Down in the lower elevation, Phyllotis darwini lunatus is found. In the intermediate altitude (~ 10-12,000 ft) is Phyllotis andium, and in the high altiplano is found Phyllotis darwini posticalis, a couple of spp. of Akodon, and maybe Calomys dusillus. Dr. Pearson, Carl, & I trapped for Phyllotis andium in a brushy rocky slope about 12,840 ft. high, 2 mi. SW Cuzapalca, Dept. Lima. The principal vegetation is Senecio and Lupino. I set 40 large Shermans along the bottom of a rocky cliff and in crevices + bushes.
