Body tadpole-shaped, subcylindrical anteriorly, compressed and tapering posteriorly, 

 enveloped in smooth skin, usually somewhat loose. Head short, broad; snout short, blunt; 

 mouth horizontal, with lower jaw included. Teeth numerous, in cardiform bands; usually 

 tricuspid on intermasillaries and mandible, simple on pharyngeals. Dorsal and anal fins 

 with rays feeble, flexible, those anterior scarcely differentiated; more or less confluent with 

 caudal. Pectorals broad, emargiaate, proeurrent under throat, some of the lower rays 

 produced. Yentrals transformable into a well-developed disk on the breast, its front below 

 or behind the middle of the head, about midway between sucking-disk and anal tin. Pseu- 

 dobranchiae present.
