ANSERES. 235 



Prycr state that it is occasionally obtained in Tokio Bay in winter, 

 but there is no skin in the Pryer collection. The example procured 

 by the Siebold Expedition was probably obtained at Nagasaki 

 (Temminck and Schlegel, Fauna Japonica, Aves, p. 125). 



The breeding-range of the Hooper extends from the Atlantic to 

 the Pacific, and it is not known that examples from the Eastern 

 Palffiarctic Region differ in any way from those obtained in the western 

 part of that Region,
