Tongue broadly heart-shaped, free behind ; vomerine teeth 

 in two short, oblique series between the posterior borders of 

 the choanae. Head a little broader than long, its width equal 

 to '/ 3 the length of head and body; snout rounded, scarcely 

 projecting, as long as the upper eyelid; canthus rostralis angular, 

 curved; loreal region oblique, strongly concave; nostril nearly 

 twice nearer the tip of the snout than the eye ; interorbital 

 space as broad as the upper eyelid ; tympanum distinct, 2 / 3 

 the diameter of the eye. Disks large, smaller than the tym- 

 panum, those of toes a little smaller than those of fingers; first 

 finger shorter than second, which is shorter than fourth; fingers 

 strongly webbed, the web reaching the disks at the outer 

 side of the second and the inner side of the fourth, nearly 

 reaching the disk at the outer side of the third finger; at the 

 first finger and the inner side of the second and third the 

 penultimate phalanges are free from the web ; third and fifth 

 toe of equal length; toes nearly entirely webbed, the web 

 reaching all disks; subarticular tubercles well-developed, the 

 distal one of the fourth finger double ; a small, oblong inner, 

 no outer metatarsal tubercle ; the heel reaches somewhat beyond 

 the tip of the snout ; tibia nearly 2 / 3 length of head and body. 



Upper parts finely granulate, with some scattered small warts; 

 throat, belly and lower surfaces of thighs coarsely granular; 

 some larger warts below the vent (partly arranged in a trans- 

 verse series) and on the heel ; a denticulated ridge along the 

 border of the lower jaw, a more distinct dermal fold along 

 the outer edge of forearm and outer finger and another one 

 along that of tarsus and fifth toe; on the arm and tarsus it 

 is undulated; heel with a triangular dermal appendage: a fold 

 above the tympanum.
