After it came another paw, and after that a great black-furred arm to which both of the paws were attached by short forearms.

The eyes jutted two inches from each side, shaded by bony protuberances overgrown with coarse hairs. But the head was chiefly terrible because of the mouth. That mouth had great yellow fangs and ran from the top to the bottom of the head, opening vertically instead of horizontally.
