 length of the head one-fonrth ; the diameter of the eye is contained 

 three times and two-thirds in the latter, equal to the extent of the 

 snout, but much less than the width of the interorbital space. 

 Mouth very protractile, oblique, with the jaws equal anteriorly ; the 

 maxillary extends to below the anterior margin of the eye. Minute 

 teeth in the jaws. The silvery band is narrow, occupying the central 

 half of the third series of scales.
