408 BATRACHIA. 



not quite one-third the length of the third and fourth. Metatarsus with one tubercle ; tips 

 of the fingers and toes truncated. 



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 nostril is situated midway between the eye 

 and the end of the snout. The eye is of moderate size, with a slight groove behind the 

 orbit. 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 openings of the eustachian 

 tubes. The lower jaw without prominences. 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 region, the sides of the 

 body, and the upper parts of the thighs 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. Brown : a 

 dark streak along the canthus rostralis ; the hinder side of the thighs with wliite spots ; the 

 lower parts brown, or whitish marbled with brown. 



One specimen was found by Messrs. von Schlagintweit in Sikkim ; another, from Nepal, was 

 sent by B. H. Hodgson, Esq. Length of the body 3f inches, of the hind leg 6 inches.

Snout triangular, depressed, rather pointed, with the canthus rostraUs very obtuse. Tym- 

 panum distinct, as large as the eye. The vomerine teeth form two short transverse rows 

 between the inner nostrils. Back with a glandular fold on each side running from the eye 

 to the loin ; short glandular folds on the middle of the back. Hind limbs of moderate 

 length, the distance between vent and knee being one-half of the length of the body. Tips 

 of the fingers and toes very slightly swollen ; the latter broadly webbed, but the web does 

 not extend to the extremity of the toes ; a cutaneous fringe along the outer margin of the 

 fifth toe ; metatarsus without lateral fold, but with two tubercles, the inner of which is 

 oblong and compressed, the outer very small and scarcely distinct. The fifth toe is a little 

 longer than the third, and the fourth much longer than either. Thumb of the male some- 

 what swollen. Vocal sacs of moderate size, one below each angle of the mouth ; their 

 internal openings are of moderate size. 



The ground-colour of the upper parts varies from brown to green and blue ; the glandular 

 fold on the side of the back being of a lighter colour and sometimes white. Generally a 

 light or white vertebral streak. Back and limbs spotted and barred with dark spots, seldom 

 uniform. A brown or black band along the canthus rostralis, continued behind the eye and 

 bent downwards behind the tympanum. No brown transverse spot between the eyes.
