The anterior dorsal fin is between the base of the ventral and the 

 vent. The height of the body is one- eighth of the total length, the 

 length of the head nearly one-sixth ; the diameter of the eye is one- 

 third of the latter, and a little more than the length of the snout. 

 Cleft of the mouth oblique ; teeth minute. {Eichards.)

Sir J. Eichardson-has examined the skeleton of this species, and 

 it appears from his description that the canal for the air-bladder ia 

 continued on to the twenty-third vertebra ; "at the twenty-fourth 

 vertebra the change fi'om lateral to inferior spinous processes is 

 complete."

The first dorsal fiji stands wholly anterior to the anus, commencing 

 just perceptibly behind the ventrals. The height of the body equals 

 the length of the head, and is one-fifth of the total. The diameter 

 of the eye is one-third of the length of the head, and more than that 

 of the snout. Teeth distinct. There are two series of scales above 

 the silvery band. (Richards.)

The origin of the spinous dorsal fin is immediately behind the 

 vertical from the vent, consequently the dorsal is much nearer to the 

 anal than to the root of the ventral ; its distance from the posterior 

 margin of the operculum is not much more than one length of the 

 head. The height of the body is contained six times in the total 

 length, the length of the head four times and a thii'd ; the diameter 

 of the eye is two-iifths of the latter, equal to the width of the inter- 

 orbital space, and much longer than the snout. Snout rather short, 

 with the jaws equal in length, and with the cleft of the mouth 

 obUque ; the maxillary extends beyond the vertical from the orbital 

 margin. Teeth distinct in the jaws, on the vomer and the palatine 

 bones. The sUvery streak occupies the third and the adjoining half 

 of the fourth series of scales. Scales with the margin entire.
