Witherby on the Western Mediterranean Shearwater. 



[On the British taken examples of the " Levantine " Shearwater. 

 By H. F. Witherby. Brit. Bds. xv. 1921, pp. 151-153.] 



Dr. Lowe has recently shown that the Shearwater 

 inhal)iting the western half of the Mediterranean is sub- 

 specifically distinct from the well-known Pvffinus pvffinus 

 yelkouan,and he has named it P . p .mauretanicus. Mr. Witherby 

 has therefore examined twelve of the twenty-eiiiht recorded 

 examples of the Levantine Shearwater, taken on the coasts 

 of the British Islands, chiefly along the Yorkshire coast, in 

 September. The twelve examined are all nndoubtedly of 

 the new race, and five others are clearly of this form from 

 the descriptions given. It seems, therefore, that the Levantine 

 Shearwater must l)e removed from the British list and its 

 place taken by the Mauritanian .subspecies, the breeding 

 place of w^iich is not known up to the present day. 



Auk. 



[The Auk. A Quarterly Journal of Ornithology. Vol. xxxviii. for 

 1921 ; 4 nos.] 



' The Auk ' for last year has suffered considerable delay in 

 publication owing to a printers^ strike ; the July number 

 was not published till 5 October, and the Octol^er number 

 did not reach us till January. The number of articles is 

 considerable, and we can do little more than mention the 

 titles of some of the more important. Of faunal papers 

 dealing with North America we find field-observations in 

 the Quebec Province by Mr. H. Mousley, in Connecticut 

 by Dr. L. B. B shop, in Florida by Mr. A. II. Howell, 

 in Arkansas by Mr. C. J. Hunt, and in Texas by Dr. T. 

 G. Pearson; and among studies of individual birds we 

 note Mr. A. O. Cross on the Dicksissel [Spiza amet'icana), 

 Mr. F. 11. Lewis on the Philadelphia Vireo, Mr. H. W. 

 Wright on the Waxwing and the Mocking-bird in New 

 England, and some reminiscences of the Passenger Pigeon 

 in Iowa in 187.2-76 by Mr. F. Bond. Mr. C. S.Arthur 

 has made a special study of the Skimmer [Rynchops nigra) ;
