IV. — Description of a supijosed new Suthora from the Dafla 

 Hills, and a Minla from the Ndgd Hillsj ivith Remarks on 

 Pictorhis (Clnysomma) altirostre, Jerdon. By Major H.

I HAVE to publish another interesting bird from the Dafla 

 hills, Assam, of the genus Suthora, closely allied to S. muni- 

 purensis^'SV aXd. & G.-Aust., described in the ^ Ibis' for 1875, 

 p. 250. The difference between them is most marked on the 

 underside, the chin being grey in the Dafla bird, paling on 

 the upper breast and belly to dull yellowish white ; while in 

 the Munipur and Nitgd species the chin and thi-oat are deep 

 black, fading to grey on the breast, into the white of the lower 

 tail-coverts. There is also a marked difference in size, this 

 new form being the smallest of the genus now known.
