Hob. Japanese coasts. 



I have not been able to examine a specimen of this bird, and 

 have therefore copied Mr. Ridgway's description. Only two 

 specimens, in the Science College Museum, Tokyo, Japan, are 

 known. 



It is possible that (Estrelala fisheri, Ridgway, which has 

 occurred near Alaska, may possibly occur also on the Asiatic 

 side.
