PREFACE. 



The collection of Parrots in the British Museum is not so extensive 

 or complete as that of the families treated of in the preceding 

 volumes. It was therefore particularly fortunate that for the 

 preparation of the present volume the aid of Count Salvadori was 

 secured, who combines with his great general experience a special 

 acquaintance with the species Jin the Italian collections, which in 

 some measure supplement that of the British Museum. I have 

 great pleasure in acknowledging the conscientious care which he 

 has bestowed on this, as on all his previous ornithological publica- 

 tions, and the attention which he has given to the purely curatorial 

 pari of the work.
