The collection of Birds made by us in Sumatra almost 
entirely within the district of Korinchi, though some few 
species were obtained at Pasir Ganting on the coast while 
waiting for our steamer, comprises about 2,097 specimens, and 
is probably by far the largest got together within a com- 
paratively limited area in the island. 
The possession of very large and complete collections of 
birds from the Malay Peninsula and from the mountains of 
Java, east and west, as well as a series of the commoner low- 
land Bornean birds from Sarawak has enabled us to go into 
the question of local races with some degree of confidence. 
Besides our own collections we are in possession ofa set of 
specimens from the mountains of the Bencoolen ang Palem- 
bang residencies and the Mt. Ophir district in Padang, 
collected by Mr. E. Jacobsen and presented to the F.M.S. 
Museums, while we have had the advantage of studying a large 
collection from various altitudes in N.E. Sumatra collected 
by Mr. A. F. C. A. van Heyst, so that, altogether, the material 
that has passed through our hands, in compiling the present 
account, has not fallen far short of six thousand skins. 
We have given the synonymy in considerable detail but 
may here recapitulate the principal separate articles dealing 
with the avifauna of Sumatra.
