Century Dictionary and Cyclopedia

1. n. A batrachian of the family Ranidæ (which see), as the common British Rana temporaria, or its North American representative, R. sylvatica. Of the true frogs there are about 250 species, belonging to 18 genera, common in most parts of the world except the Neotropical and Austrogæan regions, including for the most part aquatic or arboreal batrachians, distinguished by their agility and symmetry, as well as by their webbed toes, from the related batrachians which are popularly named toads; but the distinction is not always preserved. Of the genus Rana alone there are upward of 110 species, most of which are aquatic, are expert swimmers, and capable of making very long leaps; some are terrestrial, and some arboreal. Several different kinds of frogs are edible, as the common European R. esculenta. The largest species is the bullfrog of the United States, R. catesbiana. (See bullfrog, and cuts under Anura and Rana.) Others of the same country are R. palustris, R. halecina, and R. clamata. The toes of some arboreal frogs are enormously lengthened and fully webbed, enabling the creatures to make long flying leaps. (See flying-frog, Rhacophorus.) Some have the ends of the toes dilated, like many of the toads. The tongue of most true frogs is emarginate behind, with a process on each side. Most frogs deposit their spawn in masses in the water, and the young hatch from the egg as tadpoles, provided with a tail and external gills, which disappear with the growth of the permanent limbs. The arboreal batrachians known indifferently as tree-frogs or tree-toads are not frogs in any proper sense, but belong to a different suborder (Arcifera) of salient amphibians. (See Hylidæ.) The name frog is loosely applied, with or without a qualifying term, to some other batrachians equally remote from the Ranidæ, and locally in the United States to certain lizards. See phrases below.

5. n. A fastening for the front of a coat or any similar garment, often made ornamental by the use of embroidery or braiding, and consisting generally of a spindle-shaped button, attached by a cord, and corresponding with a loop on the opposite side of the garment. A pair of frogs fixed on opposite sides of a coat may allow of buttoning it either way, or of securing both sides at once.
