SUMMARYParker, S. A. 1971. Taxonomy of the Northern Territory friarbirds known asPhilemon buceroides gordoni.Emu 71: 54–56.Examination of all available material from the range ofPhilemon buceroides gordoniMathews as defined by Salomonsen showed that two taxa were confused under the one name, truegordoniof Melville Island and coastal mangroves of the Northern Territory mainland, and nominatebuceroidesSwainson of the sandstone gorges of the Arnhem Land escarpment, the latter form previously known only from Timor and Savu. In view of their pronounced ecological differences on the mainland,gordoniis here elevated to rank of species. Vernacular names for both forms are discussed.
