Ibilaos, a wild tribe, Philippine archipelago, who occupy both slopes of the Caraballo Sur range between the provinces of Nueva Vizcaya and Nueva Ecija, island of Luzon. The Ibilaos appear to be half-caste Malays and Negritoes, of dwarfish size and very dark complexion, cultivating no land, but living entirely on the chase, and also given to head-hunting, like so many of the uncivilised Malay peoples. A few of their hordes have been reduced, and now live in peace with the settled populations of Nueva Ecija. (Fr. Blumentritt.)
