The cat family {Fe'lidce) includes the hons, tigers, leopards or pan- thers, jaguars, pumas, lynxes, wildcats, etc. They are widely distributed in both the Old World and the New, but are absent in Australia. They seem to have evolved in the Old World first, migrating to North America at the close of the Pliocene, and from thence to South America. The legs are relatively .short and the claws are retractile. The terminal.

This is the natural position of the claw and prevents it from friction. When wanted for aggression or defense it is pulled into position by the flexor muscles bearing the claw. The raccoons (Proci/on'idce), placed by some with the bear family, are plantigrade and omnivorous, eating anything in the way of fish, oyster, crayfish, flesh or fowl, and green vegetables especially corn. They have the peculiar habit of washing their food. They are nocturnal. The limbs are long and the soles of the f(>ot naked. "The raccoon is at home in the timbered regions of the southern and eastern United States whore there are swamps," for it loves to play and to fish in the water. It has long active fingers, and uses its hands as clovcrly as a monkey. It makes its home in the hollow limb of a tree. The annual family of five or six yoimg follow the mother about for a y(\\r.
