preceding. Soft anal similar, inserted a little nearer posterior rim of 

 orbit than base of caudal, and its base like that of soft dorsal, a little 

 convex. Anal spines small, first inserted opposite origin of soft dorsal, 

 second longer, and both depressible in a groove. A short keel on abdo- 

 men in front reaching to anus. Caudal small, triangular, forked, and 

 lobes pointed. Pectoral long, falcate, and reaching beyond beginning 

 of straight part of lateral line. Ventral small, inserted a little in ad- 

 vance of origin of pectorals, and not reaching half way to origin of soft 

 anal. Anus near tips of ventrals. 



Color when fresh in arrack with upper part of body slaty-gray, 

 shot with pale metallic blue and purple, lower surface white and 

 washed everywhere with bright silvery. Upper part of spinous 

 dorsal and upper part of anterior dorsal lobe dusky, latter deeper. 

 Caudal more or less dusky on upper lobe. Base of pectoral dusky 

 inside. Fins with these exceptions pale yellowish. No opercular 

 spot. Peritoneum silvery. 



Length 5f inches.

Close to Caranx latus Agassiz,^^ but differing in the more convex 

 profile, upper lobe of soft dorsal dusky, and tip of upper caudal lobe 

 same color. Scomber heberi?^ may prove identical. 

 Caranx marginatus (Gill).

Head 3i; depth 2i; D. VIII-I, 20; A. II-I, 16; scutes in straight 

 part of lateral line 28; width of head 2\ in its length; third dorsal 

 spine 2h; first dorsal ray about If; first anal ray about 2; ventral 2\; 

 snout 3f in head, measm-ed from its tip; eye 4; maxillary 2; inter- 

 orbital space Z\; pectoral 3 in head and trunk. Depth of deepest 

 scute in lateral line about 7 in greatest depth of body. Maxillary reach- 

 ing about opposite posterior margin of pupil. Gill-rakers 7+14, com- 

 pressed, and longest a little longer than filaments or about y of orbit. 

 Adipose eyehd well developed, nearly covering posterior third of head. 

 A very pale opercular spot at upper corner of gill-opening. Fins all 

 pale except upper portions of anterior dorsal rays which are dusted
