Mt. Cacaguatique, Dept., San Miguel Salvador Nov., 21, 1925 - Dec., 23, 1925 Heterops Mt. Cacaguatique spiny-pocket mouse These mice were found commonly in the sub-tropical zone and usually near the small mountain streams. In this association they were taken in traps set under [illegible] the edges of rocks, at the base of banana trees, on brushy stream banks, or small drifts in the streams, along dripping rock walls between which the water ran, and at the waters edge. No. 10768 was taken in a wild pineapple fence, along the edge of a corn field and the coffee. This place was about two hundred yards from a stream, at one place where the transition zone along one of the canyon slopes came to [illegible] the edge of a down and bordered a stream for about three hundred yards. I caught Cacaguatique spiny-pocket mice barely within the sub-tropical zone. Here not more than ten feet from the water I set a trap baited with oatmeal by small round hole which led back and down under a cotton log. Within a week this trap caught four of these mice. Nos. 10897 & 10901 were taken at an altitude of 4000 ft. in dead brush and weeds. This was probably the highest point in the immediate region [illegible] where sub-tropical vegetation was found. Most of the stomachs examined were empty, but seed pulp, and plant pulp was what I found in those containing food.
