Pupil liorizontal. Tongue large, oval, entire, grooved 

 along the middle, free only at the sides and slightly behind. 

 Palate toothless. Two dermal transverse ridges in front of the 

 oesophagus, the second strongly denticulate. Tympanum 

 distinct. Fingers and toes free, the tips feebly dilated. 

 Outer metatarsals bound together. No prsecoracoids ; no 

 omosternum ; sternum cartilaginous, small. Diapophyses of 

 sacral vertebra feebly dilated.

Head subtriangular, a little broader than long ; snout 

 obtusely pointed, shorter than the diameter of the orbit ; 

 canthus rostralis distinct ; loreal region nearly vertical, con- 

 cave ; nostril nearer the tip of the snout than the eye ; 

 interorbital space as broad as the upper eyelid; tympanum as 

 large as the eye. Fingers and toes rather elongate, cylin- 

 drical, slender, with small terminal disks and strong sul)arti- 

 cular tubercles ; first finger shorter than second ; a feeble 

 oval inner metatarsal tubercle. The tibio-tarsal articulation 

 reaches the eye. Skin smooth ; a fine fold along the verte- 

 bral line, and sometimes several others along the back ; chin 

 with a pair of more or less distinct small warts. Grey or

Tongue circular, nicked and slightly free behind. Vomerine 

 teeth in two short transverse or slightly oblique series between 

 the large choana. Head moderate, the skin free from the skull ; 

 snout rounded, shorter than the diameter of the orbit, with 

 strong canthus and concave loreal region ; interorbital space 

 as broad as the upper eyelid ; tympanum distinct, one third 

 to two fifths th(; diameter of the eye. Fingers much de- 

 pressed, webbed at the base, disks larger than the tympanum. 

 Toes webbed to the disks of the thinl ami fifth and to the
