8/4/25 August 4, 1925 - Weather as usual dry and warm. As there was nothing in the traps I spent the day exploring. I passed up a rocky heavily wooded canyon for about a mile, then climbed the canyon wall to the ridge that led up to the untimbered region of a mountain. Here the grass was about knee high in most places and not very thick. All over the mountain side were round rocks ranging from the size of a hazel nut to large rounded and oblong boulders. Along these slopes paths, or what might be called paths, run zigzag thus I was able to work my way up the mountain. I believe that deer stay in the jungle during the heat of the day and come out on these slopes to feed during the evening. Under some of the rocks I noticed fresh digging from little holes that led down under them. The holes were large enough to admit a Norway Rat. It was a very difficult trip. I collected two more bats. Goldman refers to these as white-lined bats (Saccopteryx). As I was preparing these specimens I noticed a very small gland on the chin of the ♀ specimen. The small pouch in the wing had a peculiar color. There is only a small remnant of this pouch in the ♂.
