402 BATRACHIA. 



DICROGLOSSUS, Gthr. 



Fing-ers free ; toes broadly webbed ; tongue rather elongate, deeply notched 

 behind ; vomerine teeth none ; openings of the eustachian tubes of moderate 

 width, tympanum indistinct ; vocal sacs of the male external and lateral. 



Only one species is known. 



DiCROGLOSSUS ADOLFI. 



Dicroglossus adolfi, Gunth. Proc. Zool. Soc. 18G0, p. 158. pi. 28. fig. B. 



Skin smooth or warty ; toes webbed to their tips by a very extensible membrane ; a cylin- 

 drical tubercle at the metatarsus, very much like the rudiment of a sixth toe. Above greenish 

 or greenish brown, uniform or spotted Avith darker ; belly with dark specks. 



In habit and size somewhat similar to Bombinator ignetis, but with the snout more pointed. 

 The skin is in some specimens warty, in others smooth. The tympanum is rather indistinct, 

 and not quite the size of the eye. The inner nostrils are small and rather distant from each 

 other, the openings of the eustachian tubes larger. The limbs are of moderate length ; the 

 lingers quite free : the third is the longest ; the first is very little longer than the second and 

 fourth, which are equal in length. The fourth toe is one-fourth longer than the fifth. The 

 species varies considerably in coloration, and the most constant characters appear to be 

 brownish specks on all or some of the lower parts, and a brownish streak on the hinder side 

 of the thigh. 



Length of the head and body 1 inch 7 lines; of the fore leg 10 lines; of the hind leg 

 2 inches 4 lines. 



This species was discovered by Messrs. von Schlagintweit at Kalu and Simla, at elevations 

 of from 2400 to 4200 feet above the level of the sea. 



RANA, auct. 



Fingers quite free, none of them opposed to the others ; toes webbed ; 

 head covered with skin. Vomerine teeth in two series or groups ; tongue 

 large, oblong-, free and deeply notched behind. Metatarsus with one or two 

 blunt tubercles. 



True frogs are found in almost every part of the globe, except in Australia and in the 

 islands of the Pacific. Some of the species attain a very large size, feeding on other smaller
