Adult male. General colour above uniform dark sooty brown ; 

 ■wing-coverts like the back ; the bastard-wing, primary-coverts, and 

 quills dark brown, externally washed with the same brown as the 

 back ; tail-feathers dark brown, with a white spot on the inner 

 web of all but the two centre feathers and the outer one on each 

 side ; head like the back ; lores, sides of face, ear-coverts, and 

 cheeks uniform dark brown, with a few fulvous streaks only on 

 the cheeks ; throat and chest dull rufescent, streaked with dusky 

 brown, the feathers being mesiallj- centred with this colour ; breast, 

 abdomen, flanks, and under tail-coverts uniform dark sooty brown, 

 with a few of the feathers of the abdomen paler-edged; axillaries 

 and under wing-coverts dark brown with rufous edges ; quills 

 dusky brown below. Total length 4-8 inches, culmen 0-35, wing 

 4-05, tail 1-85, tarsus 0-35. 



Ohs. The specimens from the IS'orth-western Himalayas appear 

 to me to belong to a lighter form than typical C. concolor from 

 Southern India, and to have the rufescent shade extended more over 

 the breast. In the Museum series also there are specimens which 

 show a faint trace of a spot on the outer tail-feather as well as on 

 the centre ones. 



Tounf/. Differs from the adult in having pale rufous edges to the 

 feathers of the lower back, rump, and upper tail-coverts. 



Hah. Southern India and the greater part of the Peninsula 

 except Lower Bengal, extending into Cutch and Kattiawar and 

 occurring on Mount Aboo.
