‘“‘ Tris ranging from hazel tochestnut, to brown or orange, 
bill black, feet black or brownish black.” 
In the whole cf the Korinchi Valley, this species was 
exceedingly common in the brushwood and secondary jungle 
edging cultivation; on the sides of the valley in old jungle it 
was very much rarer, though a few were occasionally met with; 
on emerging on to the moorland zone at 10,000 feet and over 
it became very common, feeding on the Vaccinium berries and 
flying in small flocks of five or six. Whether it is a normal 
resident of these high altitudes we are, of course, unable to 
say, but Beccari collected it on Singgalang at over 5,000 feet. 
We can detect no differences between those collected in the 
valley and those from 10,000 feet, though Van Oort (Notes 
Leyden Mus. xxxiv, p. 46 (1911)), has described a subspecies, 
Crocopsis bimaculatus tenggerensis, from the Tengger Volcano in 
East Java, characterised by the diminished extent of the 
yellow area on the ear-coverts. 
No such differences are perceptible between our high and 
low level birds, taken as a series, though there are individual 
variations in this character not correlated with locality, which 
are probably due to age. All our series, however, are fairly 
adult. A large series from Mt. Salak and Mt. Gedeh, W. Java, 
can be.exactly matched by specimens in the above list.
