1927 P. & G. Los Esesmiles, Dep't, Chalatenango, Salvador February 18, 1927- A long tramp over the mountain today looked me to a well filled trapline for tropical collecting. Oryzomys obliginosis, No. 12542, was taken under the end of a cotton log, among the trees on the upper canyon slope but at a lower altitude. Two Scotinomys, Nos. 12543 and [illegible] 12544, were taken at the same altitude in similar sets. Peromyscus, Nos. 12545 to 12549 inclusive, Nos. 12551 to 12554 inclusive, and Nos. 12556 to 12558 inclusive representing two species were taken from one end of the trapline to the other, under logs, tree roots, and moss and ferns. One specimen was eaten by some prowling animal. Heteromys, Nos 12559, 12560, and 12561 were under logs and tree roots near the stream and higher along the slope. An immature Sciurus deppei, No. 12555, was caught under a large log in a snap trap baited with oatmeal. Reithrodontomys, No. 12550, was caught in the cleared pine region where I had left some traps. February 19, 1927- was spent at camp putting up specimens.
