1927 P. 10. Barra de Santiago, Dept, Ahuachapan, Salvador April 10, 1927- A large steel trap which had been set in a fresh water stream caught Procyon lotor, No. 12781. Nearly every day we saw fresh tracks of this larger species while working in the swamp forest. After returning to camp today I searched the coconut palms near one shack for bats and collected Artibeus Nos. 12782 to 12786 inclusive. There were seven of these bats hanging in one clump under a huge palm leaf. I succeeded in bringing down five when I shot into the bunch. All of these were males. Only one mammal, Liomys No. 12780, was caught in my trapline of over one hundred knap traps. During the last few days I have spent much time with scansorial and terrestrial sets but to no avail.
