latter subtruncate. Gill-rakers long and slender, fifty-seven on 

 the lower branch of the anterior arch. 



First dorsal fin inserted a little behind the middle of the body^ 

 the distance between its origin and the base of the caudal nine- 

 tenths or more of its distance from the extremity of the snout; 

 the spines are rather weak, the first almost straight, a little 

 longer than the second, and 1— ■ to 2 in the length of the head; 

 the third is considerably shorter than the second, and the bases 

 of these three spines are contiguous, but not arranged on a straight 

 line; the last is inserted well behind the others and is very feeble, 

 its length being 1^-^ to 2^^ in that of the first spine; the space 

 between the oritjins of the two dorsal fins is a little shorter than 

 the head: the first soft ray of the second dorsal is branched, as 

 long or not quite so long as the second, which is subequal in 

 height to the first dorsal fin; the last ray is not much produced, 

 and the outer border of the fin is feebly emarginate : the anal fin 

 originates well in advance of and does not extend nearly so far 

 back as the second dorsal, and the length of its base is 1^^ to 1^ 

 in its distance from the caudal; the first soft ray is as long as the 

 second and branched, longer than the soft dorsal rays, and when 

 laid back extends to or not quite to the extremity of the last ray, 

 which is not or but little produced, the outer border of the fin being 

 feebly emarginate : ventral fin well developed, with the outer 

 border subtruncate, inserted nearer to the origin of the anal than 

 to the extremity of the mandible, with a rather feeble spine; the 

 outer ray is the longest, If to 1| in the length of the head and 2 

 to 2y^Q in its distance from the origin of the anal Hn : pectoral 

 fin pointed, with sixteen rays, the two outer ones simple; the 

 second is but little stronger than the third, which is the longest, 

 the distance between its tip and the origin of the spinous dorsal 

 being a little more than half of the length of the fin, which is If 

 in the length of the head : caudal fin forked, with the tips of the 

 lobes acute, its length 3| to 34 in the total length; caudal 

 peduncle moderate and compressed, its least depth 2^ to 2| in the 

 depth of the body, and 1| to 1;} in its length.
