 and the tip of the snout or nearer the latter ; interorbital space much 

 narrower than the upper eyelid ; tympanum very distinct, | to once the 

 diameter of the eye, its distance from the latter |- to f its diameter. 

 Fingers obtusely pointed, first longer than second ; subarticular tubercles 

 rather small and feebly prominent. Hind limb variable in length, 

 but tibio-tarsal articulation never reaching the tip of the snout ; heels 

 meeting or overlapping when the limbs are folded at right angles to the

 or shorter than the foot, usually shorter than the fore lim.b. Toes 

 obtuse or somewhat swollen at the end, at least f webbed, often webbed 

 to the tips ; subarticular tubercles rather small ; a more or less deve-

 sharp-edged ; no outer metatarsal tubercle. Upper parts rarely nearly 

 smooth, usually with large, more or less prominent warts forming longi- 

 tudinal series on the back, or with more or less regular longitudinal

 present on the back ; toes webbed to the tips. 

 Tibio-tarsal articulation reaching the eye or between 



the eye and the nostril ; heels overlapping ; tibia 



ly% to 2i times in length of head and body ; 



metatarsal tubercle ^ to"| length of inner toe . Forma typica 

 Tibio-tarsal articulation reaching the tympanum or the
