We present new records of occurrence and distribution for two species of didelphid marsupials and one species of echimyid rodent. Specimens were obtained from May through August 1991 and June through August 1992 in a study of mammalian diversity of Bolivia, a joint project between the Colección Boliviana de Fauna in La Paz, the Museum of Southwestern Biology (University of New Mexico), the American Museum of Natural History (New York), the Museo “Noel Kempff Mercado” de Historia Natural in Santa Cruz de la Sierra, and the University of California at Davis. This project is an attempt to strength Bolivian collections of natural history as well as to increase the knowledge of the mammals of one of the richest yet still poorly known areas of South America. Specimens were prepared following museum standards and are on deposit in one of these collections. We also obtained tissues (heart, liver and kidney) and parasites for future studies. Most of the individuals were karyotyped and cell suspensions frozen in liquid nitrogen. All tissues, karyotypes and cell suspensions were deposited in the Division of Biological Materials, Museum of Southwestern Biology, University of New Mexico.
