THE SUNFISHES AND THEIR KIN. Perhaps the fishes best and most generally known to the boys, and consequently the elder natives of eastern and middle America, are those most frequently called sunfishes or sunnies, but which also are misnamed in various localities bream, roach, and perch. Bream and its corrupt form, brim, are, indeed, in most common use in many places, especially in the Western States. These are the most gayly colored of a family designated by ichthyologists as Centrarchids, and with popular intent sometimes dubbed the Sunfish family. All have a compressed body, which is mostly expanded vertically and almost equally beloAv and abo^e the longitudinal axis of the body. The scales are mostly rather large or of moderate size, but in some (the black basses) rather small, and the lateral line is continuous. The head is scaly and in most the suboperculum is expanded backward in an ear-like flap. The nostrils are double. The roof of the mouth is dentigerous, the teeth being in some confined to the vomer, but in most extending on to the palatines and in some also to the pterygoids and the tongue. There are mostly six branchiostegal rays, very rarely. Please note that these images are extracted from scann
