8/29/25 for the small mouse traps to hold, Next week I shall set some large snap traps. I shot two Oryzomys from their nests in the mimosa buckhard vines. The nest were of leaves and lined with fine dead grass. A cotton rat was sitting on a horizontal limb in the mimosa- brush. She was carrying four 43 mm. embyos. As I was working my way through the vines and brush I suddenly came upon two large mammals? They were obviously deer but I didn't see them very plainly before they dashed off. August 30, 1925 - cool day. Today we went up the canyon south of the lake. In the canyon where the bats are found under the large rocks I found a new species. The Salvador brown bat were not as thick as they were previously. Perhaps due to the continuous collecting there they have changed their lodging quarters. This new species 10399 was shot in a very dark corner of the rocks. For shape of tragus see serial No. 10399. I saw one female monkey carrying a young and a male and female farther up the canyon. I collected the male. His stomach content was jocotes. August 31, 1925 - very warm day. Mosquitoes very bad, angry if you please, and the little black bees more so. Collected a bat, a Gray- tailed squirrel, and an Oryzomys and hurried home.
