1927 Hacienda Chilata, Dept., Sonsonate, Salvador April 25, 1927 - Four Nyctomys were taken from my trapline this morning. No. 12842 was caught in the famous tree where No. 12809 was taken. This made three Nyctomys from that tree. Ototylomys, No. 12843, was caught on the ground at the base of a rock wall or low rock cliff. "This genus seems to favor that type of a place." Two and eaten Petromyscus were thrown away. April 26, 1927 - Reithrodonomys, No. 12850, was taken in the trap where Nyctomys No. 12809 was caught. During six nights of trapping this trap has caught three Nyctomys, one Peromyscus, and one Peithrodonomys. One night the trap would not spring. Nyctomys, No. 12851, was caught in the same trap in the uncleared area where I took No. 12843 was taken yesterday. Flesh eating wasp were at this specimen when I found it. I have had several Peromyscus mined by these insects. Late this afternoon I saw a Sciurus as it scaled a tree in which was a nest.
