166 PROCEEDINGS OF THE ACADEMY Of 



Caranx panamensis Gill. 



The height scarcely exceeds a third of the total length. The head enters 4| 

 times in the same. The diameter of the eye, within the membrane, equals a 

 fifth of the head's length and half of the snout. The jaws are even ; the supra- 

 maxillar extends to the vertical from the front of the pupil. The second dorsal 

 spine is longest, and scarcely exceeds a third of the head's length. The pec- 

 toral is rather longer than the head, and extends to the vertical of the sixth or 

 seventh anal ray. The ventral enters 1\ times in the head.

The color is silvery, with six moderately broad brown bands, between which 

 intervene six narrower ones. The first passes over the eye. In the adult 

 they are obsolete. The fins are yellowish ; the pectoral with a black axillar 

 spot. 



One specimen nearly ten inches long was sent ; another is in a former col- 

 lection of Capt. Dow. The species is extremely nearly allied to the C. speciosus 

 Lac, of the Eastern Seas. 



Genus CARANGOIDES Bleeker. 

 Carangoides dorsalis Gill. 



The body is angulated at the origin of the second dorsal and anal fins, where 

 the height equals a half of the length to the fork of the caudal. The eye's diameter 

 enters 3 times in the length of the head, and the snout 2| times. The supra- 

 maxillary reaches to the vertical from the front of the pupil. The height of 

 the suborbitar, above the middle of the cleft of the mouth, equals about a quar- 

 ter of the head's length. The first articulated rays of the second dorsal and 

 anal fins are exceedingly long, equalling the interval between the snout and the 

 root of the caudal. The pectoral fin reaches to the root of the second dorsal. 

 The ventral equals the snout.

The color is silvery, steel-blue above. The fins are yellowish ; the dorsal 

 clouded with black between the last rays. 



Two specimens. 



Genus CARANGDS (Girard) Gill. 

 Caranx Bleeker. 



Carangus marginatus Gill. 



The height enters about 3 times in the length to the fork of the caudal, and 3 

 times in the total ; the head forms a fourth of the length. The lower jaw is 

 even with the profile. The supramaxillar terminates at the vertical from between 

 the pupil and hinder border of orbit. The eye has a thin membranous eyelid 

 behind, extending nearly to the pupil ; the diameter enters 3f times in the 

 head's length and equals the snout. The breast is scaly. The pectoral is 

 longer than the head. The ventral extends half way to the interval between 

 its base, and the first soft anal ray. The lateral line is bent under the seventh 

 ray of the second dorsal, and thence armed with moderate shields.

The color above is greenish-yellow, and below silvery-yellow. There is a 

 black scapular spot, and the second dorsal and caudal are margined with 

 black. The other fins are yellowish. 



One specimen, about ten inches long, was received. 



Genus 0LIG0PLITE3 Gill. 

 Oligoplites inornatus Gill. 

 The height enters 4f times in the total length ; the length of the head 5f
