Description. The head is large, broad, flattened above and rounded in front. 

 The mouth is large; the tongue is broad, sub-round, entire, adherent posteriorly, 

 a little less so anteriorly, and is loose and movable only at its lateral margins. 

 The palatine teeth are arranged transversely in three groups; one begins behind 

 the outer margin of the posterior nares on each side, and runs for two lines 

 inwards and backwards; between the internal extremities of these groups, but on 

 a line a little in front, begins the largest group, which also runs transversely, but 

 is a little arched forward in the middle of the palate. 



The nostrils are latero-superior, near the snout, and open upwards. The eyes 

 are large and prominent, the pupil black, the iris golden, reticulated with brown. 

 The neck is contracted; the chin is smooth, and the throat has a transverse 

 strongly marked cutaneous fold. 



The body is robust and cylindrical; the tail is longer than the body, and 

 compressed at the sides so as to offer a narrow margin above and below.
