The long aud slender-billed Eed Poll is a resident of Bering Island, 

 and is probably the only form which remains there during the summer. 

 It may be, however, that it leaves the island late in winter, as I did not 

 get a single specimen between the 2d of January and the middle of 

 April, although every Eed Poll which came within shot range Mas 

 brought down for identification. 



A careful comparison with American specimens (cf. my memoir in 

 The Auk, 1884, p. 148) and with typical specimens of Sundevall's magni- 

 rohtris shows no tangible diflereuce. They are rather typical both in 

 size and color, aud represent the distinctive characters from the linaria 

 vera pretty well. 



Below I give, besides a list of the specimens obtained by me and their 

 dimensions, a table of measurements taken from Scandinavian speci- 

 mens, three of which are marked ''■ magnirostris''^ in Sundevall's own 

 handwriting.
