Puerto del Triunfo, Dept., Usulutan Dec., 28, 1925 - Jan., 25, 1924 Brown leaf-nosed Bat - Morcigalo Brown leaf-nosed bats were found commonly around the old buildings at Puerto del Triunfo. At dusk in the evening they chased up and down the porches and under the cave of the old hotel where we were staying. Although the lesser bats, their associates here, apparently stayed around close to the building all night, this species soon wandered off into the more open spaces. In the opposite end of the old hotel, where a large room had been used for a stable I saw eight Brown leaf-nosed bats clinging in a dark corner. By shooting into this bunch I collected Nos. 10959, 10960, 10961, and 10963. In another corner of the same room I saw two or three more. Others collected in the old hotel were Nos. 10924 and 11005. In the dense jungle where a little stream started suddenly with banks about four feet high, I saw two of these bats as they flew out of one hole in the bank into another. I was able to see one clinging to a root and shot it with my shot pistol. (No. 10927) In this immediate region I saw others in similar holes in the ditch bank.
