PREFACE. 



In the third volume of the 'Hand-list' Dr. Sharpe has concluded his 

 list of all the Mesomyodiau Passeres, aud has commenced the most 

 difficult portion of his work, tlie enumeration of the Acrouiyodiau 

 Passeriforines. I notice with pleasui-e the assistance that he continues 

 to receive from ornithologists of every country in what must be admitted 

 by all to be a work of great importance, and one requiring close study 

 and intimate acquaintance with the subject. 



It is lioped that the remainder of the Passeriformes will bt5 included 

 in the fourth and lust volume, which is to be published in the course of 

 the year 1902.
