della Papuasia, etc.”, reference is given to the authors of these works, to whom we 
feel deeply indebted, as indeed every ornithologist will be. As to the abbrevia- 
tion of authors’ names, we had proceeded too far to remodel them when the 
German list was issued, but we have introduced the methods recommended there 
at the headings of the species. 
We have never used the term “Malay Archipelago”, so much in vogue since 
Wallace, because this expression is incorrect in this sense, that not all the inhabi- 
tants of the islands comprehended are Malays. It is the “East Indian Archipelago” 
of which we speak, having in view the island-world from Sumatra to the Solomon 
Islands and from the Philippines to the Lesser Sundas. 
As to localities we have been as accurate as possible, but unfortunately it 
is only in recent times that collectors have attached the exact locality to every 
specimen. Formerly “Manila” meant the whole of the Philippines, “Manado” the 
whole Minahassa (Northern Celebes), “Macassar” the southern part of Celebes; 
though, for instance, Mr. W allace did not shoot all of his birds labelled Macassar 
near that town, but some at Maros and elsewhere. Of course we could not 
eliminate these inaccuracies. The future writer on the Birds of Celebes ,will 
happily have to deal with more exact data. 
Our artist, Mr. Geislcr of the Dresden Museum, Avishes us to draw attention 
to the cn-cumstance that the dull colours of some of our plates have been inten- 
tionally used at our request, the exact hue of the specimen painted being aimed 
at, sometimes at the cost of the artistic etfect and clearness of tint usually seen 
in the English productions. 
And now we have the agreeable duty of thanking all those who have lent us 
tlieir welcome aid during our six years’ work. In the first place Dr. P. and 
Dr. E. Sarasin of Basel, who placed their highly valuable and important collections 
entirely at our disposal; and not less the Hon. Walter Eothschild of Tring, 
who joined us in engaging native hunters for completing our collections and for 
making investigations on much new ground in our Area, as will be seen throughout 
the book. Mr. Nehrkorn of Riddagshausen most generously furnished us with 
a MS. descriptive of the eggs of Celehesian birds in his celebrated collection, and 
many are now described for the first time. Dr. van der Stok of Batavia and 
Prof. Neumayer of Hamburg helped us with our meteorological maps, as 
mentioned pp. 21 and 57 of the Introduction. Dr. Bowdler Sharpe of London had 
the great kindness to send us the proof-sheets of his part of vol. XXVI of the 
“Catalogue of Birds”, not yet out. Mr. Veen of Kele Londej (Minahassa) and 
Mr. North of Sydney sent us some notes bearing upon the question of migration.
