7. Descriptions of three New Species of Birds from the Indian 

 Region. By Arthur, Marquis of Tweeddale. 



[Eeceived April 14, 1877.] 



Two of the species about to be described were obtained by 

 Mr. Ossian Limborg on or near the Mule-it range of mountains in 

 Tenasserim, a locahty which had only been once previously visited 

 by a naturalist, namely, the late Colonel Tickell. The third 

 species formed part of a collection of birds made by Mr. Edmund 

 Charles Buxton in the Lampong district of Sumatra.
