BULLFROG (Rana catesbiana), the largest frog (q.v.) of North America, where it ranges from Mexico to Canada, being absent, however, from the west of the continent. In full grown specimens the body, which is green or greenish-brown above and white beneath, attains a length of 8in., and the spotted or barred hind legs, a length of io inches. It feeds on any living animal matter which it can swallow, and is in its turn devoured by snakes, fishes, herons, alligators, etc., besides being caught in large numbers for the table. The name is also applied to other large frogs.
