SYSTEMATIC LIST OF THE SPECIES. 



In preparing the present volume, my work has been greatly 

 facilitated by the loan of many specimens from Lord Roth- 

 schild's magnificent series of New Guinea birds in the Tring 

 Museum, and both to him and to Dr. Ernst Hartert I would 

 return my sincere thanks for their assistance. Dr. Hartert 

 has also kindly looked over the proofs of this volume and 

 a few points in which we differed in our conclusions have 

 since been fully discussed and revised, so that in almost 

 every instance we are now in agreement.
