abundant, feeding on the high trees in flocks of about a dozen 
individuals. It was very active and restless in its movements, 
never staying long in any one place, but was not at all shy 
and was very curious and loath to desert any companion that 
had been wounded. The note is a clear double whistle, often 
repeated. 
Comparison of the above large series with a considerable 
number from various parts of the Malay Peninsula show that 
the characters on which Ogilvie Grant separated the latter 
bird as Sibia wrayt, Bull. Brit. Orn. Club, xxv, p. 98 (1910), 
viz., the greyish instead of light drab brown sides, flanks and 
under tail coverts are quite constant.

Sumatra, Lat. 2° S. 4,000 feet. [No. 1898.] 
“Tris hazel, bill orange, feet yellow or brownish yellow.” 
This very beautiful and very active little bird only 
appeared when we reached a level of over 4,000 feet, from 
which altitude to over 7,000 feet it was extremely abundant, 
though it disappeared completely above 8,000 feet. It was met 
with in pairs and small flocks of up to about a dozen individuals, 
climbing about creepers and among fallen timber, searching 
for insects, etc. The note is a shrill one but is not very often 
uttered. 
This species with its rich scarlet crimson breast is a very 
much handsomer bird than its Himalayan and Malayan con- 
gener. Unlike that species, which differs slightly in the sexes, 
the males and females of the present form are absolutely alike. 
The species is confined to the high mountains of Sumatra 
and the genus is not represented either in Java or in Borneo.
