Body ovate or oblong, compressed, the back sometimes considerably 

 elevated, sometimes little arched. Head moderate or rather large, more 

 or less compressed. Mouth moderate or large, oblique ; maxillary broad, 

 with a well-developed supplemental bone, extending to below eye. Pre- 

 maxillaries protractile. Teeth developed in one or few series, unequal, 

 or at least not iu villiform bands. Villiform teeth usually present on 

 vomer, palatines, and tongue, wanting or deciduous in some species. 

 Gill rakers long. Eye large, with an adipose eyelid. Dorsal spines 

 rather low, connected; second dorsal long, usually elevated in front ; both 

 tins depressible in a groove. Anal fin similar to second dorsal and nearly 

 as long, preceded by two rather strong spines, its base longer than the 

 abdomen. Caudal fiu strongly forked, the peduncle very slender. Ven- 

 tral fins moderate; pectorals falcate; no finlets. Scales present, mostly 

 very small. Lateral Hue with its jiosterior portion armed with strong 

 bony plates, which grow larger on the tail, each plate armed with a spine ; 

 a short dorsal branch of lateral line usually present. Preopercle entire 

 in the adult, serrate in the young, usually with a membranaceous border. 

 Species very numerous iu all warm seas, most of them valued for food. 

 As here understood, this genus includes a considerable variety of forms, 

 diflering in the dentition and in the shape of the body. Its members seem, 

 however, to form a natural series. (Name a corruiitiou of the Portuguese 

 Jcarauua, French Caranguv. Lac^pede, however, claims to derive it from 

 Kcipu, head, "a cause de Fespece det prominence que proseute leur tete, 

 de la force de cette partie, de I'eclat dont elle brille, et d'ailleurs pour 

 annoncer la sorte de puissance et de domination qne plusieurs osseux de 

 ce genre exercent sur uu grand nombre des jioissons qui frdquentent les 

 rivages." — Lac^pede.) 



a. Teeth on vomer and palatines persistent. 



h. Soft dorsal and anal low, not muoh elevated in front, little if at all falcate; teeth in 

 jaws in one or few series, wi^th no canines. 

 Selak: 

 ■ •. Lateral line strongly arched; arch of lateral line not half as long as straight por- 

 tion; the angle under front of soft dorsal; breast scaly; lateral scutes strong 

 about 48 in number; scaly sheath of dorsal and anal very deep. Head 3^; 

 depth 3; second D. I, 24; A. I, 19; sides with broad, dark bars; a black oper- 

 cular spot; fius largely yellow. vinctus, 1310. 

 Caranx : 

 cc. Lateral lino little arched, its curved part not shorter than its straight part; max- 

 illaries scarcely reaching front of eye.
