length of the third and fourth. Metatarsus with one tubercle. Tips 
of the fingers and toes truncated. (Brown, a dark. streak along the 
canthus rostralis ; the hinder side of the thigh with white spots ; the 
lower parts brown, or whitish marbled with brown. 
Hab. One specimen, found by Messrs. von Schlagintweit in Sik- 
kim (3800 feet) ; another from Nepal is in the Collection of the 
British Museum. 
Description.—The upper surface of the head is flat, with indistinct 
canthus rostralis ; the loreal region is oblique, the snout short and 
broad, the distance between the angles of the mouth being very much 
more than the length of the head. The tympanum is hidden by the 
skin, but its outlines become somewhat visible in exsiccated speci- 
mens only; the species may be readily distinguished by this cha- 
racter. ‘The nostril is situated midway between the eye and the end 
of the snout. The eye is of moderate size, prominent above the level 
of the crown, and with a slight groove behind. The space between 
the eyes is as wide as an upper eyelid. The inner nostrils are a 
rather narrow transverse cleft, and in size about equal to the open- 
ings of the eustachian tubes. The lower jaw without prominences ; 
there are no vocal sacs, both the specimens being females. Two 
tubercular folds arise from the eye; the stronger one running above 
the tympanum to the axil, the other along the side of the back 
towards the loin; the back and the belly are smooth ; the sacral re- 
gioa, the sides of the body, and the upper parts of the thigh are 
more or less covered with broad tubercles. The toes and fingers are 
truncated or ending in small knobs. The former are webbed to their 
extremities, the membrane being slightly emarginate. The fourth 
toe is one-fourth longer than the third, which is rather longer than 
the fifth. One metatarsal tubercle. Fhe colours have been stated 
above.

Dicroctossus, Gthr. 
Fingers free, toes broadly webbed ; tongue rather elongate, deeply 
notched behind ; vomerine teeth none ; eustachian tubes moderate, 
tympanum indistinct ; vocal sacs of the male external and lateral. 
This genus is to be referred to the Ranide, and differs from Oxy- 
glossus in the shape of the tongue.
