thirds webbed; disks larger than the tympanum ; subarticular tu- 
bereles moderate ; a small inner metatarsal tubercle. The hind limb 
being carried forwards along the body, the tibio-tarsal articulation 
reaches the eye. Skin smooth, granular on the belly and under the 
thighs ; a fold above the tympanum. Greyish above, forehead and 
sides of the body lighter ; legs irregularly cross-barred ; hinder side 
of thighs colourless ; throat brown-spotted. Male with an internal 
vocal sac.

Vomerine teeth ? Tongue with a free conical papilla in the 
middle. Snout rounded; canthus rostralis distinct ; loreal region 
slightly concave ; nostril equally distant from the eye and the tip of 
the snout ; interorbital space broader than the upper eyelid; tym- 
panum one third the width of the eye. Fingers slightly, toes two- 
thirds webbed ; disks of fingers as large as the tympanum, of toes 
rather smaller ; subarticular tubercles well developed ; a small inner 
metatarsal tubercle. The hind limb being carried forwards along 
the body, the tibio-tarsal articulation reaches the eye. Skin smooth 
above, granular beneath ; a fold from the eye to the shoulder. Red- 
dish brown above, with indistinct markings; thighs colourless in 
front and behind. 
Though the single specimen exhibits no vomerine teeth, I am in- 
clined to think that this is accidental, and that therefore this species 
must be referred to Rhacophorus.
