Description. — Male and female. Resembling M. rubricapilla in general^ 
but differing in the following particulars. The marks on the chin_, throat 
and upper breast are not mere shaft-lines but broad well-defined streaks ; 
the line from the nostrils over the eye is pale yellow and the shafts are 
conspicuously black ; the ferruginous of the head is very dark, approaching 
chestnut ; the upper plumage, olive-green in M. rubricapilla, is in the 
present species rufescent, without a tinge of green ; the tail and wings are 
a deep rufescent brown. 
Rather smaller than the preceding species. 
The Javan species, M. javanicay is uniform deep rufous, almost 
chestnut, above; the sides of the head are brown, and the streaks below' 
are very broad. Another species from Java, M. flavicollis, is uniform 
rufous above, the sides of the head are grey, and the throat and breast are 
fulvous with obsolete shaft-streaks. M. borneensis is very similar to M. 
javanica, but has the throat and breast pure white with broad black streaks. 
M. woodii from Palawan resembles M. rubricapilla, but the sides of the 
head are greyish brown and the wings deep rufous. 
The Sumatran Yellow-breasted Tree-Babbler occurs in Tenasserim from 
about Mergui down to the southern extremity of the Division, where it 
appears to be common. 
It extends down the Malay penmsula to Sumatra, and Dr. Tiraut 
records it from Cochin China. 
In habits it does not appear to differ from its allied congener, M. rubr^i- 
capilla.
