Pipa \Pi*pa\, n.; pl. {Pipas}. (Zo[94]l.)       The Surinam toad ({Pipa Americana}), noted for its peculiar       breeding habits.          Note: The male places the eggs on the back of the female,                where they soon become inclosed in capsules formed by                the thickening of the skin. The incubation of the eggs                takes place in the capsules, and the young, when                hatched, come forth with well developed legs.
