Not Labrax chrysops Girard. 



Not Labrax &: 



The body is elongated-ovate, with the dorsal outline arched. The height is 

 greatest under the spinous dorsal fin, and there equals twenty-seven hundredths of the 

 entire length from the projecting lower jaw to the concave margin of the caudal fin. 

 The height is nearly uniform under the spinous dorsal ; the dorsal outline behind that 

 fin slowly declines to the end of the second dorsal; the abdominal outline ascends 

 much more rapidly from the commencement to the end of the anal fin. Behind the 

 latter fin, the height of the caudal peduncle is about a seventh of the entire length; at 

 the base of the caudal fin, it is equal to a ninth of the same. 



The head is conical in profile, slightly depressed at the nape, and thence descends 

 in nearly a straight line to the snout ? the latter being scarcely convex. The head, 

 from the lower jaw to the tip of the opercular spine, forms little more than a quarter 

 of the entire length; its height at the nape behind the vertical of the posterior border 

 of the eye is nearly equal to sixteen hundredths of the entire length. The diameter 

 of the eye is more than equal to a quarter of the head's length, and the eye is distant 

 a diameter from the snout. 



The pectinated margin of the preoperculum is slightly oblique; its teeth become 

 stronger toward the angle, and are continued on the inferior margin at greater distances 

 for about half the distance between the angle a^id the articulation with the lower jaw; 

 the anterior limb or margin of the anterior fold is vertical. The operculum lias two 

 spines, separated by an oblique emargination. 



The first dorsal fin commences over the bases of the ventrals, and is of a triangular 

 form. The fourth spine is longest, and equals an eighth of the fish's length; from 

 thence they gradually decrease in size to the ninth, which is nearly as large as the second. 

 The second dorsal is entirely separated from the first. Its spine is equal to nearly 

 half the length of its longest ray, and somewhat exceeds that of the seventh spine; 

 the last ray is less than half as long as the longest. 



The anal fin commences nearly under the fourth ray of the dorsal, and nearly 

 four of its rays are posterior to the end of that fin; the third spine is longest, and ex. 

 ceeds half the length of the first articulated or longest ray. The relative height is the 

 same as that of the dorsal fin. 



The caudal fin, when expanded, is emarginated, and its shortest rays form a sixth 

 of the entire length; the longest rays equal a quarter of the same. 



The pectoral fins are small, and only equal fifteen hundredths of the length. The 

 first two rays are simple; the third, or longest, is branched.
