The head and the anterior part of the body are very broad and 

 much depressed ; the skin is naked, thick, leathery, rugose, with 

 vertical folds on the side of the body. The head is as broad as long, 

 with the lateral profiles convergent towards the snout, Avhich is 

 obtuse. The upper surface of the head is quite flat, and the width 

 of the interorbital space is one-half of the greatest width of the head. 

 The cleft of the mouth is horizontal, curved, not extending to below 

 the eye : the lips arc thick ; the lower is divided into three portions 

 by two deep grooves; each of the lateral portions has a broad thin 

 appendage hanging downwards. The intermaxillary is very little 

 protractile, and armed with eight or ten teeth, vertically implanted, 

 the two outer on each side being small and conigal, whilst the others 

 are flat and cutting. There is a broad velum on the toothless palate.
