 nostril equally distant from the eye and from the end of the snout ; 

 distance between the nostrils greater than the interorbital width, 

 which equals that of the upper eyelid ; tympanum distinct. .', to l 

 the diameter of the eye, I to once its distance from the latter. 

 Fingers rather slender, with a distinct dermal border, the tips 

 dilated into very large discs which are a little broader than long, 

 much larger than the tympanum, with a groove separating the upper 

 from the lower surface and another above, corresponding to the 

 long transverse limb of the terminal phalanx ; first finger shorter 

 than the second, third twice as long as the snout ; subarticular 

 tubercles rather small, feebly prominent. 



Hind limb long, tibio-tarsal articulation reaching the tip of 

 the snout or slightly beyond, the heels overlapping when the limbs 

 are folded at right angles to the body ; tibia 4 times as long as 

 broad, i% to i;: times in length from snout to vent, shorter than the 

 fore limb, longer than the foot. Toes with large discs similar to those 

 of the fingers but smaller, completely webbed, the web involving 

 the base of the discs ; outer metatarsals separated to the base ; 

 subarticular tubercles rather small, feebly prominent; no tarsal 

 fold ; inner metatarsal tubercle flat, scarcely distinct, about I the
