On Phasianus ignitus and its nearest allies

While working out the ornithological results of the Dutch expedition to Central Borneo, I had to decide which name to bestow upon the Bornean Crested Fire-back, generally known as Euplocamus nobilis Scl., but afterwards united with E. ignitus Lath. by Elliot (Ibis 1878, p. 414), and lately also by Ogilvie Grant in his Catalogue of the Game Birds in the British Museum. A comparison of the Bornean specimens in the Leyden Museum with our very interesting other representatives of the Genus ¹) convinced me that we have to acknowledge not only two, as Elliot (l. c.) proposes, but four welldefined species, as will be fully explained hereafter in the key to the species.
