“ Adult, iris hazel, bill yellow, culminal region corneous, 
feet black; immature, iris dark, bill blackish horn, yellow at 
gape and tip, feet black.” ; 
This large and heavily built Whistling thrush was fairly 
common at Siolak Daras and also at Sungei Penoh, frequent- 
ing the beds of mountain streams where they debouched on 
the main valley. In the old jungle and on the higher hills it 
appeared to be displaced entirely by A. melanuva, which was 
relatively a very much commoner species. 
On comparing the above series and six adults from 
various parts of the Malay Peninsula it is evident that 
insufficiency of material lead Dr. Sharpe to entirely misplace 
this species in his key to the genus in the “ Catalogue of 
Birds” (Joc. cit.) All the adults in the series before us have 
the tips of the median wing coverts pale mauve, the shoulder 
spot is distinctly brighter than the rest of the plumage, 
though not conspicuously so and the glistening tips to the 
body feathers cannot be said to be “ obsolete,” though they 
are less marked than in other species of the group except 
A. castaneus. Buttikofer was obviously correct in regarding 
the alliances of the form to be with M. flavirvostris, of Java, from 
which it can, however, be at once separated by its very much 
larger size (wing 6.5 in. against 5.8 in the Javan bird). 
The three Sumatran adults appear to have the tail 
blacker and less glossed with blue than those from the 
Peninsula, but the differences are not constant.
