(After Jordan and Evermaun.) Fam. 4. Centrarchidae.—No subocular lamina of the sub- orbitals, or subocular shelf; entopterygoid present; palate toothed; teeth conical. Praecaudal vertebrae with transverse processes from the third or fourth to the last; ribs mostly sessile, behind the transverse processes. Two nostrils on each side. Gill-mem- branes free from isthmus ; 5 to 7 branchiostegal rays; gills 4, a slit behind the fourth ; pseudobranchiae more or less developed, often rudimentary or absent. Lower pharyngeal bones separate. Soft portion of dorsal fin not more developed than the anal. Carnivorous freshwater fishes, some entering brackish water. Many are known to build nests. Mostly inhabitants of ISTorth America, the best known being the Sun-Fishes (Lepomis), and Black Bass (Micropterus), several species of which have recently been introduced into continental Europe. Principal genera: Pomoxys, Gentrarchus, Ambloplites, Ghaenohryttus, Microp)terus, Lepomis, Massoma, KuMia. Thirty-two species are known. Fam. 5. Cyphosidae.—Plerbivorous fishes, agreeing in their essential osteological characters with the preceding, differing in the incisor-like outer teeth and densely-scaled fins. Some 14 species are known,from the Pacific and Indian Oceans, referable to 4 genera : Gyphosus (Fimelepterus), Hermosilla, Sectator, Medialuna. VOL. VII 2 u.
