To the working ornithologist and Curators of Aluseums this latest 

 contribution to s3'stematic oruitliological literature should prove a 

 most valuable help. Mr. P. Wjtsman has undertaken the arduous 

 task of Editor, and has called to his aid most of those who are 

 regarded as the leaders in the ornithological world of to-day, as, 

 for example, Dr. P. L. Sclatcr, Dr. K. Bowdler Sharpe, W. It. 

 Ogilvie-Orant, Dr. Ernst Ilartert, and Count .Sulvadori. 



Very properly, Part I deals with the Eurylaimidic and has been 

 written by Dr. Ilartert. The author, in a short Introduction, after 

 commenting on the earlier views as to the position of these birds in 

 the system, passes on to remark that later research has shown them 

 to be truly Passerine types ; and here, without further comment, 

 he leaves this aspect of the subject. More, perhaps, at the time 

 this part was written could scarcely have been said, but it has just 

 been, wo think, conclusively shown that the nearest allies of the 

 EuryLnemida) are the Cotingida;.
