PREFACE. 



THE object of the present List has been to give a complete 

 Catalogue of the specimens of the Order Columbse or 

 Pigeons contained in the Collection of the British Museum, 

 indicating the locality, and the source from whence each 

 has been derived. With this view the different individuals 

 of each contained in the Collection are indicated by the 

 letters a, 6, c, &c. following the name of the species and its 

 synonyms. 



The List of the Order Gallinae is in progress and will 

 be published shortly.
