the snout and to the width of the interorbital «pace. Snout mode- 

 rately produced, with the cleft of the mouth very oblique ; the max- 

 illary extends slightly beyond the vertical from the anterior margin 

 of the eye. Teeth distinct on the vomer and in the jaws. The 

 silvery streak occupies the fifth series of scales and the angles of the 

 scales of the series adjoining.

The spinous dorsal is rather small. The height of the body is 

 one-fifth of the total length. Snout of moderate extent, equal to the 

 diameter of the eye. ( Val.)

The origin of the anterior dorsal fin is a little behind the middle 

 of the ventral. The height of the body is one-sixth of the total 

 length, the length of the head one-fifth ; the diameter of the eye is 

 one-third of the length of the head, a little more than the extent of 

 the snout, and much more than the width of the interorbital space. 

 Snout moderately produced, with the cleft of the mouth oblique ; 

 the maxillary extends to below the antericfr margin of the eye. Teeth 

 distinct in the jaws and on the vomer. The silvery streak occupies 

 the adjoining halves of the fourth and fifth series of scales.

It is nearly impossible to determine this species from the accounts 

 given by Valenciennes and iBonaparte, and the figures illustrating 

 them are veiy indifferent and inaccuiate in several points. Valen- 

 ciennes states fifteen anal rays in the text, and seventeen in the 

 j^ormula of the fins, which latter has been copied by Bonaparte. The 

 fig^e given by the former represents fifteen anal rays, but much too 

 small an eye ; that given by the latter does not afford any idea as to 

 the number of the anal rays. The principal character of this species 

 are the scales, which are considerably larger than in the other Euro- 

 pean .species.
