" Sternum Aquiline, with convex posterior edge, and one oval 

 hole on each side ; scapulars broad." 



Mr. Gurney must have long ago received the pair fromTam- 

 suy together with my descriptions, but I have not yet learned his 

 opinion as to the validity of the species. I have followed the 

 custom prevailing in this genus of naming the species after its 

 local name. 



Besides the specimen procured near here (Takow) in January 

 1866, I received in December 1865 an immature bird, also from 

 the southern mountains. I now give the notes I have made on 

 this.

 tily barred with buff-brown shaded with black. Axillaries white, 

 varied with reddish-brown. A good deal of white occurs on the 

 underwing. On the primary and tertiary under-coverts the 

 peculiar Spilo7'nis-sty\e of spots are showing themselves. Upper 

 parts deep hair-brown, shot with purplish-pink ; the feathers on 

 their concealed halves whitey-brown,with more or less pure white. 

 White margins to the higher tail-coverts, and brown to those in 

 immediate proximity with the tail. All the small and large wing- 

 feathers are more or less tipped with white, and some of the 

 coverts are a good deal marked with it. Quills hair-brown,
