1927 3 El Tablon, Lake Guija, Sept., Santa Ana, Salvador In a crevice just barely shaded from the sunlight were two little bats clinging head down and braced with their forearms against the lava rock ledge. Their very position of clinging to the rocks immediately marked them to me as sac-winged bats, Emballonuridae. I backed off and shot them with my .410 shot pistol. Glancing shot made a pulp out of the female but the male No. 1958 — was a good specimen. More bats flew out from deeper down in the crack; I finally shot one of these at close range and identified the remains as Glossophaga. On the trap line near camp, in the subtropical second growth I had three Baiomys, one Ototylomys, and two Liomys destroyed by ants. Meal had been taken from the other traps. Also, in a muddy trail near camp I saw tracks where a Cuniculus had passed sometime late in the night.
