Palatine teeth in two strongly curved series, meeting at a right 

 angle backwards, extending outwards a good deal beyond choanae ; 

 parasphenoid teeth in two elongate patches diverging backwards, 

 well separated from each other posteriorly, and from palatine teeth 

 series ; the length of the parasphenoid patches equals the distance 

 from their anterior border to the intermaxillary teeth. Tongue 

 very large, suboval, attached narrowly along the anterior half of 

 the median line. Head moderate, convex, longer than broad, 

 greatest width at angles of jaws ; snout rounded, projecting a little 

 beyond lower jaw ; margin of lower jaw slightly projecting below 

 the eyes ; latter very large, prominent. Body cylindrical, short, 

 measuring only twice or twice and one third the distance from tip 

 of snout to gular fold. Limbs well developed ; when laid against 

 the body, the fingers and toes intercross ; fingers and toes moderate, 

 obtuse, free, inner very short ; no carpal or tarsal tubercles. Tail 

 cylindrical at the base, slightly compressed at the end, a little 

 shorter than head and body. Skin smooth, shining ; no parotoids ; 

 a strong, arched gular fold, meeting a rectilinear groove from the 

 eye; eleven costal grooves. Uniform reddish brown, lighter be- 

 neath.
