RIFLE-BIRD, the Ptilorhis paradisa, 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. P. para- diseus inhabits the S. E. districts of Aus- tralia, and is found only in very thick "bush." The male is regarded as more splendid in plumage than any other Aus- tralian bird. The upper parts are vel- vety 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 luster. The tail is black, the two central feathers rich metallic green. The female, as is often the case, is much duller col- ored than her mate.
