Some fifteen years ago Mr. H. Winge published a list of 

 Danish birds in the ' Journal of the Danish Ornithological 

 Society.' In the present ])aper the author mentions a few 

 additional species and races since recorded, and revises the 

 account of the distribution of some of the other species. 

 Among the more interesting details he mentions that the 

 Plover breeding in Denmark is very similar to the race 

 Charadrius apricarius ureophilns recently described by 

 Mrs. Meitiertzhagen. The Danish breeding Dunlin is dis- 

 cussed at considerable length, and is identified witli Erolia 

 alpina schinzi recently discriminated by Hartert. The Cor- 

 morant is now only a winter visitor; it has been exterminated 

 as a breeding-bird, and the Egy[)tian Vulture, Neophron 

 percnopterus, has been added to the Danisli list, a young l)ird 

 havincr been taken on the island of Zeeland in August 1918. 



Shvfeldt on the Ihrmudan " Cahoiv." 



r.V comparative study of some subfossil remains of birds from Beriinida, 

 including the '' Caliow." By H- W. Shufeldt. Ann. Carnegie ^luseum, 

 Pittsburg, xiii. \S\22, pp. 33:3-418.] 



Several years ago Dr. Shufeldt described in 'The Ibis' 

 three extinct Petrels, including the " Cahow/' from bones 

 collected in Bermuda. The present paper appears to be a 

 redescription of the same material together with a com- 

 parative study of the relationship of the new species with 

 various forms of living Petrels. The diflcrcnt points brought 

 out by the author are illustrated by a large number of 

 plates. Curiously enough, Dr. Shufeldt makes no reference 

 to his paper in ' The Ibis,' and one is led to suppose that the 

 three species are being described for the first time, whereas 

 in reality the original descriptions appeared in this Journal 

 for 191G.
