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

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

 mouth horizontal, with lower jaw included. Teeth numerous, in cardit'orm bands; usually 

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

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

 caudal. Pectorals broad, emarginate, procurrent under throat, some of the lower rays 

 produced. Ventrals 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 fin. Pseu- 

 dobranchite present.
