maxillary moderately broad and falciform, with its lower border 

 entire, its distal extremity rounded and extending to or a little 

 beyond the vertical from the anterior margin of the eye ; its 

 length is 24 to 3 in that of the head, and its greatest width is 2|- 

 to 2-2- in its length. No perceptible teeth. Opercle with its 

 hinder border sinuous, its lower border linear and slightly oblique, 

 and its length 1~ to 14 in its depth; subopercle very narrow; 

 limbs of the preopercle meeting almost at a right angle, the lower 

 not produced, the posterior linear and subvertical. Thirty-two or 

 thirty-three gill-rakers on the lower branch of the anterior arch, 

 the longest 14 to 2 in the diameter of the eye. 



The space between the origin of the dorsal fin and the extremity 

 of the snout is 14 to 1 ^^'^^ in its distance from the root of the 

 caudal; the second or third ray is the longest, about two-fifths 

 longer than the base of the fin and 1|- to 14 in the length of the 

 head; the outer border is truncated or very slightly rounded : 

 anal tin with the outer border emarginate, the third and fourth 

 rays the longest, as long as or a little shorter than the diameter 

 of the eye, and 1-i- to 1^ in the length of its base, which is less 

 than that of the dorsal, and as long as or a little shorter than its 

 distance fi'om the caudal ; the last ray is thickened, profusely 

 branched, and a little produced, and extends when laid back mid- 

 way to the root of the caudal : ventral fin inserted from one- 

 tenth to one-fifth nearer to the base of the caudal than to the 

 extremity of the mandible, with the outer border rounded, the 

 first ray simple and not quite so long as the second and third, 

 which are If to 2^ in the length of the head : pectoral fin with 

 fourteen rays, the outer border rounded, the second ray simple 

 and scarcely shorter than the third, which is longest, If to If in 

 the length of the head : caudal fin forked, with the lobes sub- 

 equal, 1-| to li in the length of the head; the least depth of its 

 peduncle is about one-fourth less than its distance from the anal. 



Scales smooth; axillary scale of the pectoral well developed, 



lanceolate, much longer than that of the ventral, which is rather 



shorter than the diameter of the eye; a pair of oval scales along 



the basal half of each caudal lobe.
