Palatine teeth in three series ; median series generally in a 

 straight line or a double arc, the convexity of which is turned 

 backwards, sometimes forming a single arc ; lateral series a little 

 in advance of the central and not quite half its length, sepa- 

 rated from the latter by a slight interval. Tongue large, plicse 

 radiating from behind. Head depressed, a little longer than broad ; 

 greatest width at angles of jaws ; snout broad, rounded, without 

 canthus rostralis ; eyes moderate. Body stout, cylindrical, twice 

 and two thirds to thrice and one fourth the distance from tip of snout 

 to gular fold. Limbs moderate ; adpressed against the body, the 

 median fingers and toes meet in the male, remain generally separated 

 in the female ; fingers and toes not very thick, depressed ; carpal 

 and tarsal tubercles scarcely distinct. Tail about as long as head 

 and body, compressed, pointed, not keeled. Skin shining, more or 

 less pitted ; parotoids rather distinct ; a vertical groove behind the
