Tongue subcircular or suboval, entire or slightly nicked, adherent. 
Vomerine teeth between the large choanze, in two series forming a 
FA\orafM. Habit slender, somewhat like Rana agilis. Head as 
long as broad, or a little longer than broad; snout subacuminate, 
measuring about once and one third the diameter of the orbit ; the 
distance between the nostril and the eye equals the diameter of the 
latter ; canthus rostralis angular, straight; loreal region not very 
oblique, slightly concave; interorbital space as broad as the upper 
eyelid ; tympanum very distinct, about two thirds the width of the 
eye. A very slight web between the three outer fingers, none 
between the inner; a slight rudiment of pollex; toes two-thirds 
webbed ; disks of fingers and toes much smaller than the tympanum; 
subarticular tubercles well developed. The hind limb being carried 
forwards along the body, the tibio-tarsal articulation reaches the 
tip of the snout or beyond; the tibia measures the distance from 
axilla to vent, or somewhat less. Skin smooth, granular on the 
belly and under the thighs; a narrow, straight, glandular fold from 
the eye above the tympanum, lost at a small distance beyond the 
vertical of the shoulder. Greyish or reddish brown above, generally 
with more or less distinct dark bands across the head, body, and 
limbs ; sometimes a dark vertebral line ; sides of head and of limbs 
dark brown; lower lip white, with a brown margin ; beneath whitish, 
immaculate. Male with an external gular vocal sac. From snout
