Apt. An Arctic monster. A huge, white-furred creature with six limbs, four of which, short and heavy, carry it over the snow and ice; the other two, which grow forward from its shoulders on either side of its long, powerful neck, terminate in white, hairless hands with which it seizes and holds its prey. Its head and mouth are similar in appearance to those of a hippopotamus, except that from the sides of the lower jawbone two mighty horns curve slightly downward toward the front. Its two huge eyes extend in two vast oval patches from the centre of the top of the cranium down either side of the head to below the roots of the horns, so that these weapons really grow out from the lower part of the eyes, which are composed of several thousand ocelli each. Each ocellus is furnished with its own lid, and the apt can, at will, close as many of the facets of his huge eyes as he chooses. (See THE WARLORD OF MARS.) Astok. Prince of Dusar. Avenue of Ancestors. A street in Helium. Banth. Barsoomian lion. A fierce beast of prey that roams the low hills surrounding the dead seas of ancient Mars.

It has enormous protruding eyes of green. (See THE GODS OF MARS.) Bar Comas. Jeddak of Warhoon. (See A PRINCESS OF MARS.) Barsoom. MARS. Black pirates of Barsoom. Men six feet and over in height.
