Hyla Vauterii. Bihr. MS. 
Description. — Head short, thick, the sides anteriorly converging towards a nearly right angle, the 
muzzle rounded. Tongue nearly cordate, posteriorly emarginate, free for about one-fourth of 
its length. Palatine teeth in two oval fasciculi, placed nearly transversely between the poste- 
rior nares, and almost contiguous. Eyes prominent. Tympanum circular, rather large. 
Body plump, the sides nearly parallel for two-thirds of its length. The skin nearly smooth, 
but covered with very small inconspicuous granulations over the whole upper surface, which 
are rather more obvious on the head. The throat, the belly, and the inferior surface of the 
thighs covered with large prominent granulations. Beneath the lower jaw the granulations 
are smaller, and the under surface of the limbs excepting the thighs is quite smooth. A small 
fold of skin over the tympanum passes backwards to the arm ; and beneath the throat there are 
two considerable transverse folds, one of which is before and the other immediately behind the 
arms. Fore feet, with the palms covered with small granular tubercles, and a tubercle under 
tbe joints of the fingers, which are connected to about one-third of their length. Hinder legs 
longer than the head and body by the whole foot and tarsus. The soles tuberculated. Toes 
rather short, palmate to half their length. 
Colour. — The whole of the upper parts are greyish brown, with a tinge of red, and minutely 
punctured with black. There are scattered spots of the latter colour on the back and sides, 
assuming somewhat of a longitudinal arrangement, and a broad blackish grey fascia extends
