Rifle-bird (Ptilorhis paradiseus), often spoken of as one of the 'Birds of Paradise,' is perhaps the best-known species of a genus which, according to Elliot, comprises four species confined to Australia and to New Guinea. Ptilorhis paradiseus inhabits the south-eastern districts of Australia, and is found only in very thick 'bush.' The male is regarded as more splendid in plumage than any other Australian bird. The upper parts are velvety black, tinged with purple; the under parts velvety black, diversified with olive-green. The crown of the head and the throat are covered with innumerable little specks of emerald green of most brilliant lustre. The tail is black, the two central feathers rich metallic green. The female, as is often the case, is much duller coloured than her mate. See HONEY-EATER.
