The thing was like a man, inhumanly tall and inhumanly thin; the head was long, narrow, and hairless -- the head of a predatory creature. The ears were small, close-set and queerly pointed. The eyes, set in death, were narrow, oblique and of a strange yellowish colour. The nose was thin and hooked, like the beak of a bird of prey, the mouth a wide cruel gash, whose thin lips, writhed in a death snarl and flecked with foam, disclosed wolfish fangs. The creature, which was naked and hairless, was not unlike a human being in other ways. the shoulders were broad and powerful, the neck long and lean. The arms were long and muscular, the thumb being set beside the fingers after the manner of the great apes. Fingers and thumbs were armed with heavy hooked talons. The chest was curiously misshapen, the breast-bone Jutting out like the keel of a ship, the ribs curving back from it. The legs were long and wiry with huge, hand-like, prehensile feet, the great toe set opposite the rest like a man's thumb. The claws on the toes were merely long nails. But the most curious feature of this curious creature was on its back. A pair of great wings, shaped much like the wings of a moth but with a bony frame and of leathery substance, grew from its shoulders, beginning at a point just back and above where the arms joined the shoulders, and extending half way to the narrow hips. These wings, Kane reckoned, would measure some eighteen feet from tip to tip
