2d Species. Golden-eyes Perch. Perca chrysops. 

 Perche oeuil-d'or. 



Upper jaw longer, one spine on the opercule, body 

 oblong, breadth one fourth of total length, silvery 

 with five longitudinal brownish stripes on each side, 

 head brown above : lateral line diagonal and straight ; 

 first dorsal fin with eight rays, the second has 14, 

 whereof one is spiny, tail forked, roseate, tip brown; 

 base scaly. 



Vulgar names Rock fish, Rock bass, Rock perch, 

 Gold eyes, Striped bass. &c. It is commonly mis- 

 taken for the Rock fish or Striped bass of the Atlantic 

 Ocean, the Perca Mitchelli of Dr. Mitchell, (Trans, of 

 the philos. Society of New York, vol. i. page 413, 

 tab. 3. fig. 4.) to which it is certainly greatly similar; 

 but it differs from it, by the single spine of the oper- 

 cule, the shape of the lateral line, the less number 

 of stripes, the scaly tail, &c. It is not very common 

 in the Ohio, and is hardly ever seen at Pittsburgh, 

 being more common in the lower parts of the river, 

 where it frequents the falls, ripples, and rocky shores. 

 Its usual size is about one foot. It is very good to 

 eat. It bites at the hook. The mouth is large with 

 very small teeth, the three pieces of the gill cover 

 are slightly crenulate, the middle one or preoper- 

 cule being however deeply serrate. The eyes are 

 large black with a large golden iris. The lateral 

 line begins at the corner of the opercule and does 

 not follow the curve of the back, the stripes are par- 

 allel with it and only two of them reach the tail. 

 The branchial membrane has six rays ; the spine of 

 the opercule is not terminal. The dorsal fins are 

 rufous and quite separate, the two first rays of the 

 first are shorter, the second is brown posteriorly and
