Vomerine teeth in two small groups close together behind the 
choane. Lower jaw with two slight prominences in front. Habit 
of Rana kuhlii. Head broad; snout short, rounded, with angular 
canthus rostralis ; interorbital 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-

rather small, not bony; snout short, rounded, with angular canthus 
rostralis ; interorbital space narrower than the upper eyelid; tym-

difference 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
