The carpal bones and manus are very similar, but the terminal phalanges of the digits can be withdrawn, with their sharp claws, over the penultimate phalanx. In the hind-limb and Fig. 366.—A Side View of a Cat's girdle we may note again the greater length of limb but a general similarity to the dog. There are the same retractile claws as in the fore-limb.

In the cat the tongue is armed with rasping homy papillae which assist the teeth in "stripping" bones. The intestine is always very short. The brain is well convoluted and the senses are highly developed. The external pinnse of the ear are large and triangular- shaped. Most of the "cats" have long and sensitive hairs or vibrissa on each side of the snout, useful in nocturnal prowls, as fine organs of touch. We may trace the same three series of features as were pointed out in the horse and ox, , (i) Resem- blances due to descent from a common ancestral species; (2) Resemblances due to similar modifications since that time; (3) Differences due to divergent modifications since that time. I. The Carnivora appear to be descended from very generalised mammals which combined many of the.
