b-l. 4 ¢ad.,3 ¢imm.,4 ?. Siolak Daras, Korinchi 
Valley, Sumatra, 3,000 feet. March rgth- 
28th. [Nos. 225, 265-6, 287, 299, 311-3, 388, 
454, 490.] 
m. $%,. Sungei Kumbang, Korinchi, 4,600 feet. 
March 26th. [No. 592.] 
“Adult male: iris black, bill black, slate on lower mand- 
ible, yellow at base, feet yellowish brown. Immature males 
and females: iris dark or hazel; bill horn, pink beneath; feet 
brownish, the soles yellowish.” 
In the four fully adult males, there is considerable varia- 
tion in the tint of the upper surface, which ranges from an 
almost pure black toa slaty grey. One specimen (No 265), 
sexed as a female, possibly erroneously, resembles the males, 
but has the upper surface grey, the feathers with darker 
centres. The immature males differ only from the females in 
having ill defined buffy white tips to the lesser and greater 
wing-coverts, which are barely indicated in the female and in 
having the orange buff of the under surface of a richer tint. 
Found sparingly in secondary jungle and at the edges of 
jungle clearings on the valley slopes up to about 4,500 feet. 
The species is presumably only a winter resident in 
Sumatra. Modigliani obtained it in December and January 
near the Toba Lake in N. E. Sumatra; in the Malay Peninsula 
it occurs from November to April.
