Body oblong, scarcely elevated, little compressed ; liead rather pro- 

 longed anteriorly, the mouth small, terminal and very oblique; scales 

 rather large; dorsal fin moderate; anal flu very high in the males, mod- 

 erate in the females ; ventrals long iu the males, reachiug past frout of 

 anal ; eye moderate, shorter than snout aud thau interorbital space ; a 

 slight angle formed by the profile, in front of the eye, due to the greater 

 flattening of the snout. Male flshes dark olivaceous above; sides sil- 

 very or somewhat golden, with about a dozen broad transverse bars of 

 the color of the back; posterior part of dorsal fin with a black patch;

 black band along sides about on the level of the eye and as wide as the 

 pupil; below this two similar black bars anteriorly and one posteriorly, 

 the upper one being interrupted ; one or two black bars at base of cau- 

 dal. Females usually larger thau the males. A large specimen taken at 

 Beaufort, N. C, supposed to be a male of this species in high coloration, 

 showed the following colors in life: Back olive, sides and belly bright 

 salmon yellow ; lower fins clear yellow ; pectorals and anal with some 

 dusky; posterior edge of caudal dark; dorsal nearly all black, a large 

 black ocellated spot on the last rays; opercles and under parts of head
