Coloration. Forehead, crown, and nape chestnut ; ear-coverts 

 chestnut, each feather blackish near the tip and edged with white; 

 lores, chin, and upper throat black with a chocolate tinge ; cheeks 

 mingled chestnut and black ; mantle and sides of neck olive-brown, 

 each feather with a semicircular black mark near the end ; lower 

 back plain olive-brown ; rump and upper tail-coverts slaty grey ; 

 tail ashy, suffused with golden yellow on the outer webs ; wing- 

 coverts olive-brown, the greater series broadly tipped with deep 

 ferruginous; primary-coverts and winglet yellow on the outer 

 webs, ashy on the inner ; outer webs of the primaries and secon- 

 daries bright golden yellow ; tertiaries and tips of the secondaries 

 ashy blue ; the base of the outer webs of the secondaries golden 

 red ; lower plumage pale fulvous, washed with olivaceous on the 

 sides of the body and under tail-coverts, each feather of the throat 

 and breast with a narrow crescentic black bar near the end and 

 tipped with fulvous white. 



The young are at first without the black marks on the throat, 

 breast, and back, but they soon acquire them. 



The only variation this bird exhibits is in the colour of the ear- 

 coverts ; Nepal birds have a great deal of black on the ear-coverts, 

 and the black diminishes in quantity as we proceed towards the 

 north-west, till on arrival at Chamba the ear-coverts are almost 

 entirely chestnut. 



Legs and feet pale brown ; iris pale yellowish brown ; bill black 

 (Hume) ; iris greyish brown (Scully). 



Length nearly 11 ; tail 4*8 ; wing 4-2 ; tarsus 1/5 ; bill from 

 gape 1-1. 



Distribution. The Himalayas from Chamba to Nepal, up to 

 about 7000 feet. 



Habits, $c. Scully remarks that this species moves about very 

 rapidly and noiselessly amongst bushes, and its note is subdued 

 and not unmusical.
