Rio San Miguel, 18°25'N. Feb, 2 - Feb, 21, 1924 Sigmoidon led here and there through the weeds and brush and along the wild pine apple hedges. Traps set under the old bean vines and under bunches of tall green grass at various places in the patch caught many sigmoidons. More successful yet were traps set in heavy green grass on the bank of Rio San Miguel at the west border of the old bean patch. This grass grew down to the very waters edge and was so dense that I had to part it to force my way in & set traps. I ran it a narrow strip along the river's bank as far up and down the river as I was able to get acquainted with while at this camp. The usual food habits were common; seed and plant pulp. However Nos. 11048, 11049, and 11068 had wild pine apple fruit in their stomach, it smelled so rich and strong that I first thought it to be some species of wild onion.
