10/1/25 44 Dog bats. It is quite obvious that this name has been derived from their dog like habit of [illegible] laying back their ears and persistently backing away when one approaches. Their relatively large black eyes are quite prominent. Thus hanging by their feet, braced with their foream, their ears, back and the hinderpart of their body pressed closely against the rock or wall to which they are clinging they are not nearly so conspicuous as a bat hanging head down. I should think a better name would be puppy bats or fox terrier bat. I placed small pieces of cotton in the sacs on the membrane [illegible] to make them stand out more prominent. These little sacs are quite obviously glands for when I caught males (only males care the sacs on the female they are rudimentary) the sac and membrane near it were moistened, but the sac was so small I could detect no odour. When flying these bats made a peculiar metallic sound like one that could be made by a loosely threaded cable of wires of some rich metallic substance or freshly cut iron. I was unable to discover how the sound was made. I believe the net system is a very efficient way of taking bats, for after catching a large bunch I turned them loose in a closed room and picked the specimens I wanted as well as studied their habits. At dusk I turned them loose.
