under the ground. We searched about for nearly an hour and found very few bats. My guide told me that formerly he had seen thousands of bats in the mine. The greatest number encountered were glossophaga, a representative No. 12196 was put up. I saw two carollia, No. 12195 was taken, and one diphylla, No. 12194. From this mine we went to the No. 3 mine which is perhaps three hundred yards to the south and east and across a small river or stream and just to the south of a trail that leads in that direction. The entrance tunnel led back perhaps one hundred feet before it struck a cross vein. The water was nearly knee deep in the entrance tunnel therefore my feet were soaking wet before I reached the cross vein where there was no water. At the cross vein I found Mormoops by the thousands. In some places there were large cavities where they fluttered and squeaked abundantly.
