1927 P.7 San Jose del Sacare, Dept., Chalatenango, Salvador March 15, 1927 - Two Peromyscus of the same species as No. 19723 I were destroyed by ants, also a sub-tropical Peromyscus which I caught in a dry ravine in the Oaks was destroyed by ants. This evening at 6 P.M. we returned to the place where I saw bats flying last night. At 6:10 P.M., as last night, I first saw two little butterfly like bats circling and darting about the tops of some tall pines. Finally one passed over the open space above me and I was lucky with my first shot. I spent so much time looking for my fallen bat that I didn't get a chance to shoot again. The specimen, No. 19727, proved to be Rhogeessa. Mr. van Rossem saw one of these little bats flying about through the Oaks. One large bat which I saw last evening looked very much like Nycteris. Also the squeeking about our camp sounded like Nycteris.
