From the commencement of heavy jungle on the valley 
slopes up to about 8,000 feet on Korinchi Peak this strikingly 
coloured little Nuthatch was very common, feeding on tall 
tree trunks in parties of six or seven. The species ranges 
from the mountains of the Malay Peninsula, through Sumatra 
and Java to Timor, but has not hitherto been recorded from 
the mountains of North Borneo. 
No differences in colour are perceptible between the 
present series and six skins from various mountains of the 
Malay Peninsula; the bill, however, whicii averages about 
18 mm. from gape appears slightly short. 
A very large series recently collected in East and West 
Java shows that the Sumatran as well as the Malayan birds 
are, as Hartert states, decidedly darker than the typical form 
from East Java, while the blue on the outer secondaries is more 
extensive reaching to the shaft and also to the edge except 
at the tip. In the East Javan form the blue is entirely 
surrounded by black.

It is unfortunate that we did not trouble to collect more 
of these crows, which were fairly common in the neighbour- 
hood of Sungei Penoh, though they were not nearly so 
abundant either higher up or lower down the valley. They 
also occurred, though sparingly, in clearings at Sungei 
Kumbang up to 5,000 feet. There has always been consider- 
able confusion in the nomenclature of this form owing to the 
fact that the locality of Moore’s type was wrongly given as 
Bombay, where no species of this type occurs. 
In his paper on the Birds of Nias, Buttikofer has cleared 
up the confusion and shown that the Sumatran race, though 
closely allied to, differs considerably from the typical enca 
from Java in its larger size and more slender and less arched 
culmen.
