Body moderately elongate, slender, fusiform, its greatest 

 depth one fourth of total length without caudal, its width three 

 eighths of length of head; least depth of caudal peduncle equals 

 diameter of eye; head conical, compressed, its width over 

 opercles equal to length of postorbital part; alow occipital keel; 

 snout moderately long, obtusely pointed, its length nearly equal 

 to width of interorbital space, and contained three and one 

 fourth times in length of head; lower jaw slightly projecting; 

 maxilla almost reaching to below front of eye, the upper jaw 

 one third as long as the head; mandible reaching nearly to 

 below front margin of pupil, its length equal to postorbital part 

 of head; interorbital space with a low keel between two shallow 

 furrows, its width one third of length of head; eye one fourth 

 the length of head (in young examples 5^ inches long), about 

 one fifth in older fish; gill rakers 9+27, the longest one half 

 as long as the snout. The spinous dorsal base is short, equal 

 to postorbital part of head; the spines are very slender, closely 

 placed, the longest not so long as the eye; the spines are depres- 

 sible into a sheath; the origin of the fin is over the middle of the 

 length of the pectoral. The soft dorsal originates about over 

 the end of the ventral, midway between tip of snout and base of 

 caudal; the longest ray is as long as the postorbital part of the 

 head; the fin is shaped as in Seriola, the second half being 

 very low, the last ray about two thirds as long as the eye; the 

 fin is followed by two finlets, the longest as long as the eye. The 

 caudal is deeply forked, the middle rays, from base of fin, one 

 third as long as the outer rays, which are as long as the head; 

 no keel on the caudal peduncle. The anal origin is under the 

 15th ray of the dorsal; the base of the fin is as long as the head;
