 VI.— THE PIGEOXS. 



By L.EOIVHARD i^TEJIVEOER. 



(Plato xxii.) 



The addition of several new and interest iug species of Pigeons, as 

 well as the defective state of our ktiowledfje in regard to several others, 

 induced me to take up this group. 



I take great pleasure in acknowledging the help I have received from 

 material kindly placed in my hands for examination by the authorities 

 of the Tokio Educational Museum, especially Messrs. Tegima and 

 Namiye ; by Prof. Robert Collett, Christiania, Norway ; by Mr. Harry 

 V. Hensou, Hakodate, Japan ; and by Mr. P. L. Jouy, of the National 

 Museum. Mr. H. Pryer, Yokohama, has also furnished me with some 

 valuable notes. Great praise is due to the authorities of the St. Pe- 

 tersburg Imperial Academy of Sciences for the loan of type specimens 

 received after the paper was submitted for publication.
