equals the diameter of the latter; loreal region oblique, concave ; 
canthus rostralis strongly marked, with a slight point or ridge at a 
small distance from the orbit; crown concave in the adult; inter- 
orbital space much broader than the upper eyelid; tympanum very 
distinct, about two thirds the diameter of the eye. Fingers slightly 
webbed; no projecting rudiment of pollex ; toes two-thirds webbed ; 
disks of fingers nearly as large as the tympanum, of toes smaller ; 
subarticular tubercles well developed; a slight fold along the inner 
edge of the tarsus. The hind limb being carried forwards along 
the body, the tibio-tarsal articulation reaches between the eye and 
the tip of the snout. Upper surfaces smooth or tubercular ; lower 
surfaces granulate; a fold above the tympanum. Greyish or olive 
above, spotted or marked with darker; hinder side of thighs reti- 
culated with blackish; beneath whitish, immaculate. Male with 
two external vocal vesicles, each being situated near the angle of 
the mouth; during the breeding-season the inner side of the first 
finger covered with blackish rugosities. From snout to vent 75 
millim.

Tongue subcircular, entire or scarcely emarginate, and slightly 
free behind. Vomerine teeth between the rather large choane, in 
two straight or slightly arched series. Head moderate, as long as 
broad; derm of head involved in the rugose cranial ossification ; 
posterior outline of casque nearly straight ; snout rounded, once 
and a half or once and one third as long as the diameter of the 
orbit; the distance between the nostril and the eye equals the 
diameter of the latter; loreal region oblique, concave; canthus 
rostralis strongly marked ; crown concave in the adult; interorbital 
space much broader than the upper eyelid; tympanum very distinct, 
about two thirds the diameter of the eye. Three outer fingers 
nearly half webbed ; no projecting rudiment of pollex ; toes three- 
fourths webbed ; disks of fingers as large as the tympanum, of toes 
smaller; subarticular tubercles well developed ; a slight fold along 
the inner edge of the tarsus. The hind limb being carried forwards 
along the body, the tibio-tarsal articulation reaches the front of the 
eye, the tip of the snout, or between these two points. Upper 
surfaces smooth or sparsely tuberculous ; beneath granulate ; a fold 
above the tympanum. Brown aboye, variegated with darker ; 
beneath whitish, immaculate. From snout to vent 72 millim.
