Western Himalayas it is the common frog at 4,500 ft., but at 6,000 

 ft. is entirely replaced by R. blanfordii. It is very largely aquatic 

 in habits and is not as a rule found in dense jungle. 



Mr. Kemp obtained a single specimen at Dibrugarh. 



2. Rana liebigii, Giinth, 



Boulenger, Fauna, p. 445. 



R. liebigii is very common in the Darjiling Himalayas at 

 altitudes between 4,000 and 10,000 feet; it also occurs, though 

 rarely, in the Western Himalayas (Simla and Kashmir), while to 

 the south-east its range extends to northern Tenasserim. It is 

 essentially a jungle frog and is usually found among dense under- 

 growth or at the edge of streams. 



No adults of this species were obtained on the expedition, but 

 two tadpoles were taken in a small stream near Yembung (alt. 

 1,100 ft.) on the east side of the Dihang River. 



3, Rana tigrina, Daud. 



Boulenger, Fauna, p, 449. 



Although it is apparently rare in the Himalayas, R. tigrina 

 occurs all over the plains of India. In different parts of India, 

 however, its habits differ considerably and certain structural 

 differences also seem to occur, so that it is probable that several 

 different races will ultimately have to be recognized as distinct. 

 In Bengal R. tigrina is essentially a ''tank" frog, inhabiting 

 moderately large masses of water. 



Two specimens were obtained by Mr. Kemp at Sadiya under 

 a log at the edge of the Dikrang River, 



4. Rana limnocharis, Wiegm. 



Boulenger, Fauna, p. 450. 



Being much more adaptable in its habits than R. tigrina, 

 R. limnocharis has an even wider range than that species. It is 

 equally at home in flooded rice-fields and at the edge of rocky 

 streamlets in the densest jungle. Both in the Himala^^as and in 

 the mountains of Burma it ascends to an altitude of at least 6,000 

 ft. 



Mr. Kemp obtained specim.ens at Sadiya, Kobo and Rotung 

 and in the Si^^om valley below Damda. 



5. Rana alticola, Boulgr. 



Boulenger, Cat. Batr. Sal. Brit. Mus. (2nd ed.), p. 63, fig. 

 (1882). 



The range of this frog is considerable both in longitude and 

 latitude and also in altitude. Colonel Alcock obtained specimens of
