838 AMPHIBIA. 



This species approaclies M. liexadactyla and i?. cyanophlyctis, but it is distin- 

 guished from the former by its distinct and smaller tympanum, larger yomerine 

 teeth, by the absence of the transverse fold between the orbits, by its emarginate 

 interdigital membrane, and by the character of its coloration ; and from the latter by 

 its distinct and smaller tympanum, prominent yomerine teeth and by the metatarsus 

 being destitute of a fold. On the other hand, it is more alhed to M. tigrina in the 

 character of its vomerine ridges, and still more so to JR. Imhlii in its fang-like pro- 

 cesses in the lower jaw, the character of its tympanum and metatarsal tubercle. 



It occurs at Mandalay, but I did not observe it in the neighbourhood of 

 Bhamo, below which town, however, I obtained one example of R. kuhlii, which is 

 the common frog in the Kakhyen hills and in the high valley of Hotha.

I obtained one example of this species in the second defile of the Irawady 

 on the left bank of the river, and numerous specimens of all ages at Ponsee in the 

 Kakhyen hills and from the still higher elevation of Hotha further to the east. 



In all of these examples, the skin of the head and back, and of the upper 

 surface of the thighs, is perfectly smooth, but in the young there are a few 

 obscure tubercles on the sides of the body. All the specimens, however, with 

 the exception of an adult male, have the inner aspect of the tarsus, the under- 

 surface of the metatarsus, and the upper surface of the lower half of the calf of 

 the leg roughly tubercular, the tubercles being especially large on the latter region. 

 The metatarsal fold and the fringe of the toes are also roughly granular. The toes 

 are completely webbed, but the membrane is more or less emarginate. 



The young are light greenish-brown marbled with darker, but the adults are 

 generally so dark that the marbling cannot be traced. There is a black band 

 between the eyes in young specimens, and a pale yellow band from the snout through 

 the eye to the tympanum. The under surface also is quite smooth, and is yellowish 

 mottled with dark-brown on the throat and chest, the sides of the abdomen and 

 on the under surface of the limbs. Some of the young specimens show indistinct 

 dorsal folds. Only one out of the 33 collected shows a yellowish dorsal line. The 

 fang-like apophyses of the lower jaw are well developed. 



These specimens resemble the types in the Leyden Museum in having the 

 sides of the body slightly tubercular, but, unlike them, they have the skin of the 

 surface of the body thrown into fine folds, marked by small eminences with pore«
