 Scales large, ctenoid, about 28-05 between the base of the pectoral and 

 the hypural joint ; they extend forward to between the hinder margins of

 operculum. Kows of minute pores extend ai'ound the eye, across the 

 cheek, behind the preoperculuni, and on each side of the mandible. Mouth 

 rather small, oblique, lower jaw longest ; no barbies. A band of villiform 

 teeth in each jaw, palate toothless. Tongue broad, snbtruncate or 

 rounded anteriorly, and largely free. Gill-openings separated by a rather 

 narrow isthmus, the membranes not united across it. Exposed edge of 

 shoulder girdle a smooth, curved ridge. Pseudobranchiae present ; about 

 eleven gill-rakers on the lower limb of the first arch, which are stout and 

 longer posteriorly, becoming tubercular anteriorly. D. v-viii/10-lo ; A. 

 lO-l'l ; V. i/5. Caudal rounded.
