and squeaking of flying bats was very loud and piercing. Some seemed to be landing in the tree, but I never saw one alight. I had been looking up into the tree for about 5 minutes hoping to get a shot at a settling bat when I became aware of a pair of eyes too large for Marmozos. Shot down a q Philander with 4 furred pouch young. On the way home stopped at the 3 railway culverts. In one hanging on the sides were about 6 bats. Shot 1 (wounded) and ran into the tunnel to get it and was severely bitten on one finger - a fairly deep flap of skin almost completely cut out in one girls nip. Bled profusely. Wrapped the beast in my handkerchief and waited for the others to return. One of them returned several times but flew out each time as soon as my light reached him. In the next tunnel, however, was another bat, which I shot. This (and the first) was a vampire. Got one more a little later in the first tunnel - all probably between 9:30 and 10. One had considerable blood in intestines. July 20 Skinned til about 10:00 then went down railroad to Quebeca Fajas, down Fajas to Meghelen, up Fajas to yard, then back to camp. Saw no Stlydysterys, several Crispyerson on phone wires. A little above the R on the south bank of the Fajas found a nice hollow tree leaning over the stream. No bats in the tree but a dozen or more bats of 2 species in the dark "caves" among the roots in the bank. Shot 9. Many flew out at each shot, but most would return. A few flew off and a few hung up
