Yomerine teeth in two small groups close together behind the 

 choante. Lower jaw with two slight prominences in front. Habit 

 of Sana Jcuhlii. Head broad ; snout shurt, rounded, with angidar 

 canthus rostralis ; interoi'bital space narrower than the upper eye- 

 lid ; in the adult, the derm of the sides of the head and of the fore- 

 head becomes involved in the rough cranial ossification ; tympanum 

 about half the size of the eye. First finger shorter than second ; 

 the difference between the first and second fingers is the same as 

 that between the second and third ; subarticular tubercles of fingers 

 and toes not much developed ; inner metatarsal tubercle elongate, 

 rather indistinct ; no outer tubercle. The hind limb being carried 

 forwards along the body, the tibio-tarsal articulation reaches the 

 tympanum or the eye. Skin slightly tubercular above, smooth be- 

 neath ; a fold of the skin uniting the posterior edges of the upper 

 eyelids, and extending from the eye, over the tympanum, to the 

 shoulder. Upper parts brown, marbled with darker ; upper lip and 

 sides of body and limbs with small light spots ; hind limbs cross- 

 barred ; whitish beneath, the male's throat brown. Male with two

Yomerine teeth in two indistinct groups behind the choanae. 

 Lower jaw with slight traces of bony prominences in front. Head 

 rather small, not bony ; snout short, rounded, with angular canthus 

 rostralis ; interorbital space narrower than the upper eyelid ; tym- 

 panum not distinctly defined. Pirst finger shorter than second : the 

 diff'erence of length between the first and second fingers is much 

 greater than that between the second and third ; tips of fingers 

 pointed ; toes with a short, but very distinct web at the base ; sub- 

 articular tubercles of fingers and toes not much developed : inner 

 metatarsal tubercle elongate, rather indistinct ; no outer tubercle. 

 The hind limb being carried forwards along the body the tibio-tarsal 

 articulation reaches the tip of the snout. Skin strongly tubercular 

 above, smooth beneath ; a fold of the skin uniting the posterior edges
