 beyond the mouth : canthus rostralis very obtuse ; loreal region 

 oblique, feebl}' concave ; nostril equidistant from the e5'e and from 

 the tip of the snout ; the distance between the nostrils greater than 

 the interorbital width, which is much less than that of the upper

 and about twice its distance from the latter. 



Fingers obtusely pointed, first much longer than the second, 

 third not or but slightly longer than the first, as long as the snout ; 

 subarticular tubercles well developed and very prominent. 



Hind limb rather short, the tibio-tarsal articulation reaching 

 the tympanum or the posterior border of the eye, the heels 

 feebly overlapping when the limbs are folded at right angles to the 

 body; tibia 3 to 3^ times as long as broad, 2, to 2\ times in length 

 from snout to vent, a little shorter than the foot, .shorter than 

 the fore limb. Toes obtusely pointed, J or ^ webbed ; outer
