scales. Bases of anterior and elongated dorsal and anal rays also with 

 scaly sheaths into which fins are more or less depressiblc, and on pos- 

 terior rays scales gradually disappear. Base of caudal covered with 

 small scales, and a cutaneous keel at base of each lobe laterally. Arch 

 of lateral line about If in straight portion. Greatest depth of keels or 

 scutes about 8 in greatest depth of body. Tubes in lateral Hne simple. 

 An axillary pit at base of ventral. 



Spinous dorsal inserted opposite first | of depressed ventral, third 

 spine highest, and others graduated down. Soft dorsal lobe higher 

 than spinous fin, first ray highest, and origin of fin nearer front rim of 

 orbit than base of caudal. Last dorsal and anal rays longer than those 

 preceding. Soft anal similar to soft dorsal, though inserted nearly 

 midway between base of caudal and posterior rim of orbit. Anal 

 spine small, short, second longest, and first inserted nearly opposite 

 origin of soft dorsal. Caudal large, forked, lobes slender, sharply 

 pointed, and about equal. Pectoral long, falcate, upper ray much 

 longest, and reaching well beyond beginning of straight portion of 

 lateral line or dorsal and anal lobes. Ventral inserted a trifle behind 

 origin of pectoral, and reaching over half way to origin of spinous anal. 

 Spine small, slender, weak, and over half length of first or longest ray. 

 Anus a little nearer tips of ventrals than origin of spinous anal. 



Color in alcohol dull olivaceous-brown above, lower surface whitish 

 or pale. Evident silvery reflections over most of lower regions. Fins 

 brownish, lower ones paler, and dorsals and caudal a trifle more brown- 

 ish. Iris dull brassy. Peritoneum pale silvery. 



Length L3f inches.

This species appears to differ from Caranx crysos chiefly in its more 

 elongate fusiform body, higher dorsal and anal rayed lobes, and espe- 

 cially the longer pectoral. I have not had the opportunity of compar- 

 ing small examples of C. pisquetus.
