1927 R.S. Hacienda Chilata, Dept, Sonsonate, Salvador Small fruit seeds in the faeces gave evidence of its fruit eating habits. April 27, 1927- The trapline had three common Peromyscus and an Ototylomys which was destroyed by ants. West of the hacienda house is a deep canyon bordered at frequent intervals on either side by perpendicular lava rock cliffs. The clear water in the stream flows over rocks worn round and smooth by erosion. It was along these cliffs in semi-cave or coves that we found more specimens of the New Genus. They were actually found in little cup-like depressions where they were concealed from out side. We found three hanging on the wall under some close clinging vines. Saccopteryx were found more in the open. We saw five.
