1927 P.S. Hacienda Chilala, Dept, Sonsonate, Salvador were some evidences of the passing of these rats. Bills measured averaged four mm. long. April 24, 1927 - Last night another Tylomys, No. 12827, was caught at the base of the large tree where one was taken yesterday. This rat was caught in a little pocket or depression in the trunk. Bills measured eight mm long. Ototylomys, No. 12828, was caught in the trap that caught Marmosa, No. 12816. I heard the trap snap while I was hunting at night and made my way up through the vines to it. The trap that caught the two Nyctomys and the Peromyscus was carried and wouldn't spring. Early this morning I saw an adult Sciurus when it dropped some green fruit out of a tree. This was near where I saw a squirrel a few days ago. Later in the morning I saw these two thirds grown Sciurus feeding on leaves in a fence. When I stood perfectly still they continue to eat and paid no attention to me.
