fourth; laminae longer than the rakers; rakors six plus twenty-one on the 

 front edge of tlie first arch, longest not half as long as the eye. Pseudo- 

 hrancliia3 well developed, of about twenty lainint\3. Tongue large, free. 

 Vent between the ventrals, a short distance backward of their bases, mid- 

 way between the eye and the anal fin. 



First ray of the dorsal longest, more than half as long as the head, about 

 the length of the snout farther back than the first ray of the pectorals, 

 above the axil of the ventrals. Anal origin two and one fourth lengths of 

 the head from the end of the snout, midway from the back of the eye to the 

 end of tlie tail. Adipose dorsal above the eighth and the ninth ra3'S of the 

 anal, at the beginning of the posterior third of the entire length. Pectorals 

 narrow, elongate, three fourths as long as the head, reaching as far backward 

 as the dorsal, and farther than the ventrals. Caudal deeply forked. 



Scales hard, convex, glossy, marked with fine concentric stria), subcarin- 

 ate on the back. Lateral line prominent, nearly straight from the upper 

 edge of the opercle to the base of the candal.

The outlines of this species closely resemble those of Sco2}cIengys frhiis,

 Body compressed, greatest depth about one fourth of the length from the
