The body is broad and depressed anteriorly, compressed posteriorly, 

 covered with a tough and naked skin. The length of the head is 

 one-third of the total, and its greatest mdth is two-thirds of its 

 length ; its upper surface is flat, gently sloping doAATiwards to the 

 snout ; the interorbital space is very broad, its \\idth being twice 

 the horizontal diameter of the eye. The snout is much depressed, 

 broader than long, and nearly twice as long as the eye. The cleft 

 of the mouth extends to below the anterior part of the orbit ; the 

 jaws are equal in length anteriorly, with broad hps, the upper and 

 lower lip being dilated into a flap on each side. Both nostrils are 

 pro\dded "nith short tentacles; that of the posterior, however, is 

 minute. The lower angle of the gill-covei-s is produced posteriorly 

 into a short cutaneous flap. The peculiar characters of the giU- 

 apparatus and of the adhesive disk have been stated in the generic 

 diagnosis. The ventrals, composed, as usual, of four rays and one
