“ Not only are there three toes in each foot, as in Hipparion, but the inner and the outer toes are so large that they must have rested upon the ground. Thus, so far as the limbs are concerned, the Anchitherium is just such a step beyond the Hipparion as the Hipparion is beyond the Horse, in the direction of a less specialised quadruped. The teeth are still more divergent from the Equine type. The incisors are smaller in proportion, and their crowns lack the peculiar pit which characterises those of Equus and Hipparion. ”
