The crocodile of America, superior in every detail to the crocodile of the effete monarchies of the Old World. Herodotus says the Indus is, with one exception, the only river that produces crocodiles, but they appear to have gone West and grown up with the other rivers. From the notches on his back the alligator is called a sawrian.
A large carnivorous reptile of the Crocodile family, peculiar to America. It has a shorter and broader snout than the crocodile, and the large teeth of the lower jaw shut into pits in the upper jaw, which has no marginal notches. Besides the common species of the southern United States, there are allied species in South America.
