Tongue subcireular, entire, scarcely free behind. Vomerine teeth 
in a straight or slightly curved, scarcely interrupted series on a 
level with the hinder edge of the choane. Head moderate, a little 
broader than long, rough, the derm involved in the cranial ossifica- 
tion ; snout rounded, once and a half or once and two thirds as long 
as the diameter of the eye; loreal region oblique, concave ; canthus 
rostralis angular; crown slightly concave; imterorbital space much 
broader than the upper eyelid; tympanum very distinct, about two 
thirds the diameter of the eye. Three outer fingers one-third 
webbed ; no rudiment of pollex; toes nearly entirely webbed; disks 
of fingers about as large as the tympanum, of toes rather smaller ; - 
subarticular tubercles well developed. The hind limb being carried 
forwards along the body, the tibio-tarsal articulation marks the 
front of the eye or a little beyond. Upper surfaces smooth or 
with small tubercles ; lower surfaces granulate; a curved fold above 
the tympanum. Brown or olive above, marbled with darker; whitish 
beneath, immaculate. Male with two external vocal vesicles, each 
being situated behind the angles of the jaws; during the breeding- 
season the inner side of the first finger is covered with blackish 
rugosities. From snout to vent 90 millim.
