Gallardo Museo Argentiiio de Ciencias Naturales Buenos Aires INTRODUCTION In the course of a general study of the Neotropical Bufonidae, I received some material from the British Museum (Natural History) (BMNH), the American Museum of Natural History (AMNH), the Carnegie Museum (CM) and the Museum of Zoology at the University of ]\Iichigan (MZUM) which in-eluded the new forms described below. One of these is a quite different form of Bufo from the State of Amazonas, Brasil; another is a subspecies of Bufo spi7iulosus from the Department of Oruro, Bolivia, and the last a new species of the Bufo ockendeni group from the Department of Cochabamba, Bolivia.
