The last dorsal ray produced into a long filament. The height of 

 the body is one-third of the total length (without caudal), the length 

 of the head rather less than one-fourth. Lower jaw but slightly 

 prominent ; the maxillary extending somewhat beyond the vertical 

 from the front margin of the eye. No teeth on the palate ; tongue 

 generally with a very narrow strip of minute teeth. Operculum 

 entirely smooth. Gill-rakers very fine, nearly as long as the eye, 

 closely set. A^entral fin inserted below, or nearly below, the middle 

 of the base of the dorsal. Origin of the dorsal fin considerably 

 nearer to the end of the snout than to the root of the caudal. There 

 are fourteen abdominal scutes behind the base of the ventral fins. 

 Length of the pectoral fin three-fifths of the distance of its root 

 from the ventral fin. Scales regularly arranged, nearly smooth, the 

 stria) being exceedingly fine. An indistinct bluish spot on the 

 shoulder. Each scale on the back with a dark spot, the spots form- 

 ing longitudinal series.
