Extract

Body fusiform, sometimes rather deep; median fins large, the caudal deeply cleft, inequilobate; dorsal and anal triangular, acuminate, the dorsal situated nearly opposite the interval between the ventrals and the anal; base of ventrals not extended; pectoral rays articulated (except a varying amount of the commencement of the principal ones). Fin rays ganoid, closely set, striated; fulcra closely set, minute. Scales sculptured, of moderate size, rhomboidal, their posterior borders frequently denticulated or serrated; the anterior overlapped area very narrow, reduced to a mere margin. Suspensorium very oblique; gape extensive; operculum well developed, oblong; interoperculura square-shaped; no suboperculum. Branchiostegal rays numerous; the anterior one of each lateral series broader than the rest a median lozenge-shaped plate in front.
