Puerto del Triunfo, Dept, Usulutan Dec., 28, 1925 - Jan., 25, 1926 Marmosa Pigmy opossum- Two Pigmy opossums were taken by me at Puerto del Triunfo, No.10958 was caught in vines leading down from the top of a tree at the edge of semi-dense jungle. It was caught in a small snap trap baited with oatmeal. The trap was about four feet from the ground. Three nights before this specimen was trapped I saw what I decided was a Pigmy opossum in these vines and shot at it with my shot pistol, [illegible] Its eyes shined faintly but I could see it quite clearly in the ray of light from my carbide hunting lamp as it [illegible] head downward to one of the vines. No. 11004 was caught in a small snap trap baited with oatmeal and set on a mass of small vines in tangled second growth. The little trap had come down on its [illegible] neck but did not kill it. I took it to camp [illegible] alive and [illegible] a large holdfast rat trap down slowly on its neck so as not to kill it. Its tail was obviously prehensile so we tested its strength. Mr. van Rossem allowed the little opossum to get a good wrap on his finger with its tail then I slowly let the weight the trap come to bear on its neck,
