DESCRIPTIONS OF TWO NEW GENERA AND 



NINE NEW SUBSPECIES OF BIRDS 



FROM MICRONESIA. 



BY 



TOKUTARU MOMIYAMA, M.O.S.J. 



The following descriptions of birds from some Micronesian 

 islands are based on specimens contained in the collections of the 

 Ornithological Society of Japan, of Mr. K. Kobayashi in Yokohama, 

 and of the present author. I was engaged in ornithorogical collec- 

 ting in Micronesia during the last year. 



Here I beg to tender sincere thanks to Mr. N. Kuroda for his 

 kind help on this work and publication of this manuscript. Further 

 my thanks are due to the late Dr. I. Ijima for the valuable advice 

 given me on several occasions.
