an adipose eyelid. The belly is compressed to an edge, which 

 is armed with sharp serratures. Mouth small, transverse; the 

 lower jaw the shorter, jaws toothless. The maxilla does not 

 <^xtend to the middle of the eye. Gill rakers numerous, mod- 

 erately long and slender; gill membranes deeply cleft and free 

 from the isthmus; pseudobranchiae well developed; lateral line 

 wanting. The dorsal fin is placed nearly over the middle of the 

 body, slightly behind the origin of the ventral. Its last ray is 

 produced into a long filament. The pectorals and ventrals are 

 rather long and each is provided with an appendage formed 

 of several elongate, overlapping accessory scales. The caudal 

 is deeply forked. Anal very long, its last rays low. The stomach 

 is stout and short, resembling the gizzard of a hen.

The depth of the body is contained two and two thirds times 

 in the total without caudal, the length of the head four and 

 one third times. Eye longer than snout, one fourth length of 

 head. The third ray of the dorsal is two thirds as long as the 

 head, and the filamentous ray nearly equals the head in length. 

 Length of dorsal base about one half that of head; anal base 

 twO' sevenths of total length of body without caudal, its longest 

 ray two thirds of length of ventral or one third of that of head. 

 Pectoral three fourths as long as head. Lower caudal lobe
