Adult male. Whole of the upper parts dark grey ; top of the head, 

 nape, back, rump, and upper tail-coverts tipped and barred with 

 black : wing-coverts the same, but mostly blotched with black on 

 the subterminal part of the inner web ; flight-feathers blackish, 

 barred with pale Iniff on the outer web, except the first primary, 

 which is narrowly margined with buff on the outer web, and the 

 last secondaries, which are barred on both ; forehead, lores, super- 

 ciliary stripe, chin, and throat dark chestnut ; a white stripe from 

 the gape to the eye and continued behind to the dark grey car- 

 coverts ; neck and upper parts of chest grey, shading into tawny 

 buff on the breast and belly, each feather with a black shaft-stripe 

 and those of the breast and belly with a wide black subterminal 

 cross-bar : under tail-coverts black, tipped and spotted on each web 

 with white ; tail mottled and barred with dark grey and black. 

 Total length Cro inches, wing 3-4, tail 2, tarsus 1-05. 



In immature viales the last secondaries are black, more widely 

 barred with tawny buff ; otherwise the plumage is as above. 



Adult female. Differs from the adult male in having none of the 

 dark chestnut markings on the head, chin, and throat, the two 

 latter being white or whitish grey and the breast and belly buff 

 instead of tawny. 



An immxtture female has the last secondaries marked like those of 

 the immature male, but is otherwise similar to the above.

 Under this title a specimen in the Military Library at Manilla is briefly 

 characterized as follows : — '• Head greenish black : breast vinous red, streaked 

 with black ; sides pale red with blaok spots."' This description is so vague 

 that it is impossible to form a decided opinion on it, but probably the bird 

 represents a distiuct species of this genus, inhabiting Luzon.
