Rio San Miguel, 13°25' N. Dept., San Miguel Feb., 2, 1924 - Feb., 21, 1924 Oryzomys Oryzomys were found commonly in the old weedy bean patch and [illegible] in the tall green grass on the river bank of Rio San Miguel. As for Sigmodon in the same place, snap traps baited with oatmeal were used, and set in likely spots under the heavy green grass and old dead bean vines. I saw Oryzomys occasionally in the wild pine apple hedges far out along the edges of dry fields sometimes as [illegible] as two miles from water. No. 11074 had what I thought to be Sigmodon hair in its stomach. The stomachs of others contained seed and plant pulp.
