Habit slender. Head moderate, as long as broad. Snout short, 

 scarcely prominent, obliquely truncate, quite as long as the eye ; 

 canthus I'ostralis strong. Loreal region vertical, slightly concave 

 in the upper part. Interorbital space broader than the upper 

 eyelid. Tympanu.m exposed, vertically oval, about one-third the 

 diameter of the eye. The distance between the anterior border 

 of the tympanum and the posterior corner of the eye equal to 

 half the distance between the anterior corner of the latter and 

 the nostril. Fore limb slender, equal in length to the distance 

 between vent and tympanum. Fingers moderate, much depressed, 

 webbed at the base, dilated and truncate at the end, first a little 

 shorter than second. The hind limb being carried forward along 

 the body, the tibio-tarsal articulation reaches the posteiioi- border 

 of the eye. Toes half -webbed, but the three distal phalanges of 

 the fourth toe fi-ee. The tips of the toes less strongly dilated than 

 those of the fingers. Subai'ticular tubercles well marked. Two 

 well-developed metatarsal tubercles, the inner the larger. Skin 

 of the upper part of body and limbs covei-ed with numerous small 

 round warts, irregularly di.sfciibuted; the largest situated behind
