THE TREE-PARTRIDGES. 167 



Although this species has been known to science for more 

 than a century, its habitat still remains unknown ; and, so far 

 as I am aware, the only specimen at present known is that 

 in the Leyden Museum. It has been suggested that the 

 Philippine Islands might probably prove to be the home of 

 this bird, but although most of them have now been visited by 

 various naturalists, we are still no nearer the solution of the 

 mystery.

[Plate XIV.) 

 Adult Male and Female. — Crown dark chestnut, shading into 

 brown on the nape ; sides of the neck and cheeks rust-red, 

 spotted with black ; feathers of the back olive-brown, margined 

 but not barred with dusky ; eyebrow-stripes grey ; throat and 

 fore-neck rust-red, divided from the rich chestnut chest by a 

 white and a black band ; breast and belly grey. Total length, 

 II inches; wing, 5-4; tail, 2*2 ; tarsus, i*6. 



Nothing is known of the habits or nidification of this re- 

 markable species, the only specimens as yet obtained having 

 been collected by the late Mr. Mandelli's hunters in the damp 

 dense jungles of the Bhotan Doars and Native Sikhim. The 

 whole of that ornithologist's splendid collection, having been 

 purchased at his death by Mr. A. O. Hume, now forms part of 

 the Hume collection in the British Museum.
