Sibia pulchella, G. Austen. 



The bird now described as new was obtained during the cold 

 season of 1872-73, when I was employed on the Boundary 

 Survey of the Naga Hills and Munipiir. Other species Collected 

 at the same time, and those lately described in a paper read 

 before the Zoological Society, form part of a collection of birds 

 I have been bringing together on the north-east frontier of India. 

 Lists of these have been given from time to time in the 

 " Journal of the Asiatic Society of Bengal/' Vol., XXXIX., 

 Part 2, 1870 ; Vol. XLL, Part 2, 1872. '
