 Paratractus, GILL, Proc. Ac. Nat. Sci. Phila., 1862, 432, (pis<juelits=crysos). 



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 in 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 

 fins 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 fin strongly forked, the peduncle very slender. Ven- 

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

 very small. Lateral line with its posterior 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 membrauaceous border. 

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

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

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

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

 Acarauna, French Carangue. Lacepede, however, claims to derive it from 

 ndpu, head, "a cause de 1'espece de. prominence que pr6sente leur tete, 

 de la force de cette partie, de Pe"clat dont elle brille, et d'ailleurs pour 

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

 ce genre exercent sur un grand nombre des poissons qui fre"quentent les 

 rivages." Lace"pede.) 



o. Teeth on vomer and palatines persistent. 



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



jaws in one or few series, wijth no canines. 

 SELAH: 



c. 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%; 

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

 cular spot; fins largely yellow. VINCTUS, 1310. 



CARANX : 



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

 illaries scarcely reaching front of eye.
