摘要：
Seventeen species of podocopid and platycopid Ostracoda were recorded in the 26 samples studied from the DSDP (= Deep Sea Drilling Project) Site 515B, Brazil Basin. The Trachyleberididae (eight spp.) and Krithidae (four spp.) are the most-represented families. Most species were left in open nomenclature because of scarcity or poor preservation. The assemblages composition shows moderate similarity to previously-studied deep-sea assemblages. The distribution pattern of the Eocene-Oligocene deep-sea ostracodes is briefly discussed as a contribution to the understanding of Paleogene ostracode zoogeography.
