Jan 15 Caught 2 more of this species in the traps last evening. Habitat was the thick grassy hill side about rocks at Cuzco. The tall dried wild oat stalks form a very dense cover, especially about rocks where they are protected from cattle grazing. Jan 14 Caught 5 of this species since yesterday. Jan 17 Took an animal from my traps this morning. This species of animal that I have taken him during the past 4 days he is found predominantly in the tall grass near the floor of the canyon where more brush and rocks are to be found.
