Adult morphology The tongue is small, subcircular and distinctly nicked behind, The vomerine teeth are placed in two oblique series ,between the small round choanae. The head is of moderate size, and has the derm completely involved in a faintly rugose cranial ossification, which extends to a semicircular line, running between the posterior borders of the orbit's with the convexity behind. Only the upper eyelids, the tip of the snout and a narrow strip of the free border of the upper lip are soft. The ossification forms no casque nor any ridges. The snout is rounded, distinctly longer than the orbital diameter; the canthus rostralis is angular and the loreal region high and slightly concave. The nostril is situated near the tip of the snout, its distance from the eye being as large as the orbital diameter. The interorbital space is considerably broader than the upper eyelid; in the male the tympanum is very distinct, in the female its blind border evanishes into the skin, in the latter it is,1/2 in the former more than 1/2 of the orbital diameter. A faint ridge is to be seen above the tympanum. The first finger is as long as the second; the fingers are slightly webbed at the base, the web extending as narrow dermal folds to the small disks. Toes half webbed; on the 4th toe the web is attached to the third distal joint,, on the inner side at its base on the outer side at its middle. The disks of the toes are small, somewhat smaller than those of the fingers, which are not larger than half the tympanum. There is a small oval inner metatarsal tubercle, no outer. The hind limb being carried forwards along the body, the tibiotarsal articulation almost reaches to the tip of the snout. The skin is minutely granulate on the upper parts, on the sides, the chin, the belly, and on the thighs it is coarsely granulate. The colour in spirit: The body above is reddish yellow with small black dots and large brow spots, bordered with black and disposed in pairs on the back; in the male specimen the foremost pair is fused together into a large transversal hour-glass-shaped spot immediately behind the ossification of the head; as shown by the figure. these spots are separated and placed at some distance behind the posterior border of the ossification in the female. The parts around the opening of the dorsal pouch of the female are dotted with pink. In both sexes there is behind the shoulder a longitudinal curved brown spot, bordered with black and surrounded by white. This spot is continued into a black stripe above the tympanum, extending along the loorder of the upper eyelid and the canthus rostralis to the tip of the snout where it joins its fellow. The tip of the snout and the upper eyelids are brown, the ossified surfaces of the head green with some small dark dots in the male. The outermost rim of the upper lip is black and bordered above by a narrow white line. The sides of the body like the upper parts but are sprinkled with white. The under surfaces are uniform yellowish white, the throat and the chin being lighter than the belly. The colour of the extremities corresponds with that of the body; the upper parts have regular brown crossbands, bordered with black. The tympanum is blackish brown. The male has a large external vocal sac below the mouth. The dorsal pouch of the female is small; its opening is placed,about at 1/4 of the distance between the vent and the nose and its cavity extends to the middle of the back. The tympanum of the male is distinctly larger than that of the female, and in these two specimens the limbs are longer in the female but not more than that the difference might be an individual variation. The colour, as well, is the same in both specimens, but in the male the dark spots and minute dots on the back tie more numerous than in the female. Male total length: 45 mm. Female total length: 51 mm.
