DESCRIPTIONS OF THREE NEW BIRDS FROM CHINA 



AND JAPAN. 



BY J. H. RILEY. 



[By permission of the Secretary of the Smithsonian Institution.] 



Mr. Arthur de C. Sower by, who has been collecting natural 

 history material for the U. S. National Museum in the Chinese 

 Empire for a number of years, has from time to time sent in 

 small lots of birds. During the past year a much larger series 

 of fine skins was obtained in the Province of Chihli and from 

 Manchuria, and a comparison of this material with that already 

 possessed by the Museum has enabled me to differentiate a few 

 forms not included in Mr. Sowerby's collections. These are 

 described below. 



As the distribution of the birds in the Chinese Empire, espe- 

 cially the interior, is not any too well known, I intend later to 

 prepare a catalogue of Mr. Sowerby's collections, including such 

 data as a study of his material permits. 



For the loan of a series of seven specimens of Dryocopus 

 martixis martins, the author is indebted to the authorities of the 

 Museum of Comparative Zoology.
