Gill-opening carried forward till opposite front margin of orbit. 

 Rakers 7 + 25, a little longer than longest filaments, or a trifle over half 

 of eye, compressed, rather thin, and pointed. Pseudobranchise small. 

 Isthmus narrow, but not trenchant. 



Scales small, cycloid, discoid and imbricated. Head naked, except 

 a patch of scales on cheek adjoining eye, opercle, and upper posterior 

 side. Anterior portions of soft dorsal and anal with scaly sheaths. 

 Spinous dorsal with a low basal sheath. Bases of caudal and pectoral 

 scaled. Straight portion of lateral line beginning below origin of soft 

 dorsal, curved portion about 2f in straight portion, and broadest 

 scutes about 4^ or less in depth of body. 



Spinous dorsal small, spines slender, depressible in groove, third 

 longest, and origin of fin well behind that of pectoral, or much nearer 

 origin of soft dorsal than posterior rim of orbit. Soft dorsal inserted 

 much nearer tip of snout than base of caudal, and anterior rays ele- 

 ^■ated, first developed ray longest. Soft anal similar, but its insertion 

 posterior and nearly median in body. Anal spines inserted in advance 

 of soft dorsal, depressible in a groove, and second longer. Caudal 

 deeply forked, lobes long and pointed, and upper much longer. Pec- 

 toral a little longer than head, falcate, and reaching opposite base of 

 fourth ray. Ventral small, pointed, inserted below origin of pectoral, 

 and length about equal to eye. 



Color when fresh in arrack with bright silvery prevailing, back and 

 upper surface of head pale slaty-gray. A large blackish blotch nearly 

 equal to ej^e on upper part of opercle and shoulder-girdle. This is also 

 reflected inside gill-opening. Snout dusky above. Fins pale brown- 

 ish, upper portions of dorsals and caudal dusky. Iris yellowish. 

 Peritoneum pale and whitish. 



Length 5| inches.

This species is related to Caranx kalla Cuvier,^^ from wdiich it is 

 distinguished, however, by the broad armature of the lateral line. 

 Upon comparison with Swatow examples" of kalla the scutes were 

 found constantly much narrower than in inegalas'pis. In the latter 

 they are always equal to a little over orbit. Scomber kleinii^^ is also
