Herdrickson 1950 Marmosa Oct. 28 5 km. N Villavicja, 1400 ft, Neila, Colombia, S.A. Perico brought in an uninjured specimen, captured under the rail of the R.R. tracks just W of camp. He and Pouleo were out jacklighting at the time. The local name is "Liron" or "liromito". It is to be kept alive for return to the U.S. if possible. The tail is kept in a tight "watch-spring" coil most of the time I have observed it. Murine opossum
