O PTEEOCLID^, 



Adult male. Top of the head greyish ochre ; chin and throat 

 black, as also a line commencing behind the eye and extendiug 

 along the side of the head ; rest of the head bright rufous buff, 

 gradually shading into ochre on the neck. Upper back and scapu- 

 lars dull olive-ochre, each feather margined with greyish and most 

 of the scapulars with a subterminal patch of ochre. Lower back, 

 rump, and upper tail-coverts yellowish buff barred with black. 

 Chest pale rufous, separated from the neck above and the white 

 breast and rest of underparts by two narrow black lines. Primaries 

 and greater primary-coverts grey, the outer web of the first primary 

 and the terminal part of the inner webs of the five inner primaries 

 blackish ; the latter are also margined at the extremity with white. 

 Secondaries white, the external half of the outer web and last 

 third of the inner web black, margined with white ; the inner 

 secondary, median, and all the lesser wing-coverts white, with the 

 greater part of the outer web and in the two latter the terminal part 

 also of the inner web bright chestnut, with a narrow submarginal 

 white and black band. Outer secondary and median coverts have 

 the ends yellowish buff, margined by a black band. Shoulders grey. 

 Axillaries pure white. Tail-feathers (16) blackish grey, mixed with 

 ochre and barred with pale rufous ; the centre pair produced into 

 long blackish filaments, and the remainder tipped with white. 

 Total length 14-8 inches, wing 8-4, tail 6-3, tarsus 1-1. 



In nearly mature birds many of the feathers of the top of the 

 head and a few of the long scapulars and feathers of the back are 

 yellowish biaff, barred with black, and the black throat-patch has 

 still a few white feathers mixed with the black. 



In a yorinr/er bird these differences are yet more marked, and 

 none of the yellow subterminal blotches characteristic of the scapu- 

 lars of the adult are to be seen, while the throat-patch is more 

 white than black, and each feather of the sides of the head and neck 

 has a subterminal black spot. 



In quite young male and female specimens the plumage resembles 

 that of the immature female, but the whole of the head, neck, and 

 chest are pale rufous buff barred and marked with black, and the 

 extremities of the primaries and primary-coverts are as usual tipped 

 with white. 



Adult female. The top of the head, nape, back, rump, and 

 upper tail-coverts yellowish buff barred with black. Chin and 

 throat white, rest of the face as in the adult male but paler ; 

 the front and sides of the neck are covered by a wide black 

 band edged with buff, succeeded by a grey band edged with black. 

 The chest and rest of the underparts resemble those of the male, 

 but the former is paler. The scapulars, outer secondary, and 

 median coverts are barred like the dorsal feathers ; but in the 

 former each feather is terminated by a somewhat wide band of slate- 

 grey followed by an equally wide band of tawny-yellow edged with 

 black, while in the two latter the subterminal band is white instead 

 of slate. The inner secondary and median coverts are white, 

 margined with black along the outer web ; and the rest of the
