 De Vis). 



Body elongate, sabcyliudrical anteriorly, compressed posteriorly. It 

 is wholly naked ; lateral line defined by a groove along which are fleshy 

 swellings on the tail portion. Head subquadrilateral, with raised ridges 

 of papilhe radiating from the eye, on the cheeks, opercles and mandible. 

 Eye obsolete. Mouth very oblique, with broad lobulate lips ; mandible 

 with barbies. An outer i^ow of subulate teeth in each jaw, followed by a 

 narrow band of villiform ones ; no teeth on the palate. Tongue thick, 

 rounded anteriorly, largely adnate to the floor of the mouth. Gill- 

 openings broad, lateral, separated by a wide interspace ; exposed edge of 

 shoulder-girdle smooth. Four branchoiostegals. One long dorsal fin, 

 with six spines and about 38-48 branched rays, the last united with the 

 caudal base. Anal similar to the soft dorsal. Pectorals well developed, 

 with bifurcate rays. Ventrals united into a large disc, with one spine'
