Brush-tailed bettong

The woylie or brush-tailed bettong (Bettongia penicillata) is an extremely rare, small marsupial that belongs to the genus Bettongia. It is endemic to Australia. The two subspecies are B. p. ogilbyi and the now extinct B. p. penicillata. A species first described by J. E. Gray in 1837, based on a specimen, the skin and skull of an adult male, obtained by the Zoological Society of London and placed with the British Museum of Natural History. The origin of the holotype has not been determined, but it is presumed to be New South Wales.
