Description. The head is very large, rounded at the snout, and flattened 

 above. The mouth is large; the tongue is broad, circular, extensively attached, 

 and is only slightly movable at its anterior and lateral margins. The palatine 

 teeth are arranged in three groups transversely, a small group behind the posterior 

 nares, with a larger group occupying the middle of the palate. 



The nostrils are antero-superior and very near the snout. The eyes are large 

 and prominent, with a black pupil and dusky-grey iris. 



The neck is contracted, and has a large transverse fold at the throat. The 

 body is large and sub-cylindrical. The tail is stout, longer than the body, much 

 compressed laterally, and terminates in a rounded extremity. 



The anterior extremities are short, thick, and sustain four fingers, slightly 

 palmated at their roots. The posterior extremities are much larger, and termi- 

 nate in five toes, the external of which is fimbriated on its outer margin.
