across them, thus suggesting the presence of vomerine teeth. They are small frogs, 

 the largest measuring only V'66 from the tip of the snout to the vent. 



i?. yunnanensis differs from D. adolfi in having a broader snout; its nostrils 

 placed further apart ; not so broadly webbed toes ; and the membrane of the fourth 

 toe stopping short at the distal end of the second phalanx, while in D. adolfi it 

 reaches to the extremity of that toe. The metatarsal tubercle of the latter species 

 is, unlike that of R. yunnanensis, rather free and pointed ; and a small tubercle exists 

 at the base of the fifth toe, which does not occur in R. yunnanensis, and the folds 

 along the inmost and outermost toes are much broader than in the last-mentioned 

 species. 



It is distinguished from R. huUii by its shorter and more rounded snout, and 

 by its nostrils being placed more superiorly and nearer to the eye than in that 

 species, and more on the upper surface of the head ; the canthus rostralis being 

 but little developed. Other features by which it is recognizable from R. huUii are 

 its visible tympanum, complete absence of apophyses on the lower jaw, and by its 

 widely separated vomerine ridges. 



It is closely allied to R. verrucosa, Giinther, from Malabar, but differs from it 

 in its broader snout, and in its laterally compressed sharp-edged metatarsal tubercle, 

 but this structure has none of the pronounced character which is assumed by the 

 metatarsal tubercle of Fyxicephalus.

In the specimens from Ponsee and Hotha the snout is pointed, and in a few 

 there are distinct traces of a metatarsal fold. In some cases it can be detected on 

 one leg and not on the other. The cutaneous fold along the fifth toe is well 

 developed. In the males, a large black patch involves the anterior half of the 

 vocal sacs. 



This is a very common species in the Hotha valley, but the adults are not so 

 large as specimens in the valley of the Irawady.
