 greater coverts and quills dusky brown, externally olive-yellowish, 

 vthe primaries margined with brighter yellow ; tail-feathers ashy

 towards the end of the outer web ; over the eye a long white streak 

 from the base of the nostrils to the sides of the nape ; round the 

 eye a ring of white feathers, dusky in front and behind, where it 

 adjoins the dusky spot in front of the eye and the upper margin of 

 the ear-coverts ; feathers below the eye and ear-coverts ashy 

 whitish, browner along the upper edge of the latter ; cheeks and 

 entire under surface of body bright yellow, the flank-feathers long 

 and silky, with a subterminal shade of white ; under wing-coverts 

 yellow, as well as the edge of the wing ; axillaries white, slightly 

 washed with yellow ; quills ashy brown below, white along the edge

Ohs. The specimens of this bird from the Xorth-westeru Hima- 

 layas are generally rather more ashy brown on the head, and are 

 rather larger ; in this state they are Gryptolopha albosujyerciltaris 

 of Indian authors. These birds can, however, be matched by some 

 Nepalese examples. In the Eastern Himalayas the specimens have 

 the head rather clearer blue-grey, and are smaller in dimensions 

 {Gryptolopha xanthoschista, Hodgs., and C. jerdoni. Brooks).
