Witherby on British Birds. 



[On tbe Wliite-billed Northern Diver as a British Bird. British 

 Birds, xvi. 1922, pp. 9-12, 4 photos.] 



Mr. Witherby finds amongst the many British records of 

 Cohjmbus adainsii only two which he is able to confirm with 

 certainty — one taken Deceml)er 1S.2J) in Northumberland, 

 now in the Hancock Museum at Newcastle, and one taken 

 in the spring of 1852 near Lowestoft, now in Mr. J. H. 

 Gurney's collection. ]\lr. Witherby has been unable to 

 examine three records. He adds some remai'ks on the 

 differences between the ordinary Great Northern Diver and 

 the White-billed Northern Diver.
