impression that it is a smaller form. This is, in my opinion, incorrect. It is true 

 that the form which breeds in Europe, from Scotland, Holland, and Northern 

 Germany through Scandinavia, North Russia, and, apparently, as far north as 

 Kolguev, Waigats, and Nova Zemlya, is smaller than the Siberian forms ; but 

 the name of the European form must be E. a. alpina, because in 1758 Linnaeus 

 described it from Lapland, and, as far as I can see — and Miss Jackson, after 

 long and careful studies, agrees with me — there is no difference between Dunlins 

 from Lapland, Norway, Scotland, and Riigen. There is, however, a great 

 individual variation in Dunlins, and some specimens have much longer bUls than 

 others. It is quite possible that in winter Siberian Dunlins appear in Europe, 

 among the European form. The subspecies from Eastern Siberia is very distinct 

 and must be called Erolia alpina sakhalina {Scolopax sakhalina VieUlot, Nouv.

 stern's Reise, pi. 84 — cf. Novitates Zoologicae, 1916, p. 95. The status of the 

 form from Western Siberia is as yet uncertain ; birds from there seem to be 

 generally larger than E. a. alpina, such small birds as in Europe do, apparently, 

 not occur in West Siberia. If separable, the West Siberian bird must be called
