. Elements of zoölogy. Zoology. Fig. 207.—Young of the Nile Polypterus, show- ing external gills, dr. a ray and spine (Fig. 207). The young have external gills (Fig. 207, br). Order IV. Garpikes [Byoga- noidei).—The garpikes (Fig. 208) have beak-like jaws with sharp teeth; the scales are large and re- semble white enameled plates. The air-bladder is lung- like, and the fishes are often seen at the surface inhaling air. They occur in the Western and Southern rivers and Great Lakes. The eggs are hatched the last of May. The scales are used as arrow-tips by some Fig. 208.—Garpike {Lepid

General Characteristics.—In these fishes (Figs. 193, 194) bone takes the place of cartilage. The skull is com- posed of many bones ; the optic nerves cross each other ; the gills generally number four pairs, and have several opercular or protective bones. Eels (Afiodes).—The eels are without ventral fins. The Anguilla is common in the United States, living in fresh-water streams, but depositing its eggs, often 8,000,- 000 to a single fish, in the ocean, the young ascending the rivers. The sexes are difficult to distinguish ; the females have the highest dorsal fin, smaller eyes, and a lighter color than the males, while the snout is generally broader at the tip than in the male. The conger-eel attains a large size, and ranges from Newfoundland to the West Indies. In.
