alpina alpina, but recent authors in Germany and England have 

 separated it, under the 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 Lap- 

 land, 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 Rugen. 

 There is, however, a great individual variation in Dunlins, and 

 some specimens have much longer bilis 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 cailed Erolia alpina sakhalina 

 (Scolopax sakhalina Vieillot, Nouv. Diet. d'Hist. Nat., III, p. 359, 

 1816, from Sachalin, ex Tilesius, Atlas zu Krusenstern'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 Europa do, apparently, not occur in West-Siberia. 

 If separable, the West Siberian bird must be called Erolia alpina 

 pnsilla (Falk): Scolopax pnsilla Falk, Beytr. z. topogr. Kennt. 

 Russ. Reiches, III, p. 371, 1786, »Issettische Provinz«, i. e. near 

 the Isset, in the Government of Tomsk in West Siberia«. 



• Denne Opfattelse vil dog næppe kunne fastholdes i sin Hel- 

 hed, og skønt Rylens Racer ere behandlede paa samme Grund- 

 lag i nævnte Forfatters »Vogel der palaeark. Fauna«, Heft XI — XII 

 Aug. 1920, S. 1574 — 77, synes dog enkelte deri fremsatte Bemærk-

 endelig afgjort. (Se til Eks. under 1909 Erolia alpina pnsilla 

 (Falk) og Fodnote Side 1577). 



Fastholdes den, vilde det betyde, at man havde en østsiberisk- 

 amerikansk Form, Erolia alpina sakhalina (Vieill), der var stor, 

 langnæbbet og lysere farvet, en vestlig siberisk Form, der ogsaa 

 var stor og langnæbbet, men farvet som den typiske, og som 

 — hvis den kunde skelnes fra den typiske — skulde hedde 

 E. alpina pnsilla (Falk), og endelig den typiske. 



Formodningen er altsaa, at den vestsiberiske Form skulde
