 The head is short, the snout obtuse. The upper jaw is greenish-yellow, the lower 

 yellowish-white. The nostrils are very near the extremity of the snout, and 

 placed on a rounded prominence. The eyes are large and very prominent, almost 

 resembling warts or excrescences; the pupil is black, the iris golden, very brilliant, 

 and subdivided into four portions by two black lines. The tympanum is small.
