Other examples have a mark over each eyebrow, the fore-limbs nearly to the hands, the hinder part of the thighs, the legs from the knee to the ankle, and the whole under side iron-grey; the ankles and hind part of the heels white, yellow below. (_Indris variegatus_, Gray.) All stages between the forms here described and complete {108}albinos are known; so that the various differences observed prove them to be only individual variations of the same species. DISTRIBUTION.--The Endrina is confined to the woods looking eastward, on the two high ranges along the eastern coast, between the Bay of Antongil on the north and the River Masora on the south. HABITS.--The "Endrina," "Bàbakòto," or "Amboanala" (Dog of the Forest), as the natives variously name this species, has the same habits as the Sifakas. It is the largest of the Lemurs, and is diurnal. It derives its appellation of "Dog of the Forest" from the doleful, dog-like howls which it utters. In this habit it differs, therefore, from most of the other groups (except the True Lemurs), which are, as a rule, rather silent. Its powerful voice is due to the distensible resonator which it possesses in its laryngeal pouch, described above. Essentially diurnal, the Endrinas live in small companies, and feed only on vegetable diet. The hook-like fingers of their hands are better adapted for climbing than for prehension, and much of their food is, indeed, seized by the mouth. They are entirely arboreal, and move about the trees in an erect position, rarely coming to the ground. The "Bàbakòto" is held in great veneration by most of the native tribes.
