“Tris chestnut, bill and orbital skin smalt, the former 
duller, feet sage green.” 
Common along the coast among the Casuarinas and the 
vegetation around them, not so numerous in the Korinchi 
Valley, where the species was found in secondary jungle and 
at the edge of cultivation and in gardens. 
The original types of this species came from Bencoolen, 
and the birds from Pasir Gantang are therefore practically 
topotypes. They agree perfectly with the Korinchi birds and 
differ but very slightly from those of the southern part of the 
Malay Peninsula, Mixornis pileata, Blyth. Those from the 
northern parts of the Peninsula, M. r. connectens, Kloss, are more 
olive above and on the outer aspect of the wings and have the 
throat stripes narrower. They are merging into M. rubricapillus 
(Tick.) from India and Burma.

“ Adult female: Iris hazel, bill black, feet brownish black.” 
“Timmature male: Iris hazel, bill black, the mouth yellow, 
feet black.” 
This very aberrant Whistling Thrush is apparently 
represented in collections by about six specimens only, viz., 
the male type from Mt. Sago, Padang Highlands, collected by 
Carl Bock, a pair from the same locality collected by Klaesi, 
a female from an unknown locality in the British Museum, a 
male from the South end of the Toba Lake, North Central 
Sumatra, secured by Modigliani, a male from the Sibajak 
Volcano in the Battak Highlands to the north of the same 
lake, in the collection of Baron van Dedem, and one obtained 
by Martin in approximately the same district in 1894.
