paper) any examples of Linue's ^g. hiaticola hiaticola from 

 the topo-typical locality, viz. Sweden (Middle and South), 

 with the result that I very unwisely jumped to the conclusion 

 that Swedish birds would turn out to be identical witli the 

 smaller and darker race of Ringed Plover which inhabits the 

 tundras of Russia, Siberia, and possibly Norway. 



As a matter of fact they are not identical, although I was 

 led to think so from seeing dark Norwegian specimens. 



Moreover, there still appears to be some doubt as regards 

 the question whether the race which inhabits the British 

 Isles is or is not identical with the typical race inhabiting 

 Sweden {cf. Brit. Birds Mag. vol. ix. p. 8 & pp. 79-80). 



Dr. Hartert, I believe, is quite convinced that they do not 

 differ. Herr Schioler, on the contrary, in an exhaustive 

 paper (Dansk. Ornith. Forenings Tidsskrift, March 1915, 

 pp. 161-181) on the various races of the Common Ringed 

 Plover, has lately held that they do ; but he disagreed with 

 my statement that the British race is the larger. In this, 

 of course, he was right, since, as I have just said, I was 

 unfortunately comparing the British race with the tundra- 

 breeding race. 



Since then Prof. Lonnberg has very kindly sent me five 

 breeding-plumage specimens from Middle and South Sweden 

 (type-locality), and, as a result, I have come to the conclusion 

 that without a much larger series it is impossible to come to 

 any satisfactory conclusion on this question (for even in the 

 small series sent there appeared, judging merely from size, 

 to be two distinct races, corresponding to the two localities 

 represented). 



As regards, however, Ringed Plovers from the tundras of 

 Russia and Siberia, there seems to be no doubt that these 

 represent a distinct subspecies of the typical race. There 

 seems, also, to be no doubt that this race requires naming, 

 for, as implied by Dr. Hartert and Miss Jackson (' Ibis,' 

 1915, p. 533), Meiietries's name of intennedius (Cat, Raisonne 

 Caucasus, p. 53, 1852, Lenkoran) cannot apply to these 

 tvxndra birds, and must be considered as a synonym of 

 jEff, dubius curonicus. 



I have carefully read Menetries's description of intermedius,
