VI PREFACE TO VOLUME II. 



in making his drawings for the plates accurate in detail, which was 

 so essential for their purpose. 



The authors of the various sections of Volume II are as 

 detailed in the Introductory Note (p. *v) to Volume I, but it must 

 be pointed out that besides the descriptions and sections on 

 " Characters and Allied Forms " of the Ducks and Waders, Mrs. 

 Meinertzhagen (formerly Miss A. C. Jackson) most kindly under- 

 took also those of the Swans and Geese, and for this very welcome 

 assistance the Editor, who is responsible for the descriptions and 

 characters of the rest of the birds, is most grateful. 



Attention should be drawn here to the list of Additions and 

 Corrections, which bring the work up to date, and to the Systematic- 

 List, both of which appear at the end of this volume. 



The Editor.
