382 APPENDIX. 



Anser fabalis. Latham's name has two years' priority over 

 Anas segetum Gmelin, used in the 1st edition of the 

 List and by Saunders. 



Anser erythropus. Hartert (Hand -list of British Birds, 

 p. 129) uses the name Anser finmarcliicKS Gunnerus, 

 1767, for the Lesser White-fronted Goose, as he states 

 that Anas erythropus, Linn., 1758, is not de terminable ; 

 recently Lb'nnberg (Ibis, 1913, p. 400) has given very

 White-fronted Goose, which breeds in northern Sweden, 

 while the larger form, Anser albifrons, never does so. 

 The Committee have accepted Lonnberg's determi- 

 nation.

<jenus BRANTA. Type by subsequent designation of

 clear, it will perhaps be more correct to refer to A. 0. TT. 

 Check-List N. Amer. Bds. 1886, p. 126. 



Branta bernicla. The oldest specific name is that of Linnaeus ; 

 it was not used in the 1st edition of the List as it would 

 have involved the use of the same generic and specific 

 name. 



Genus CYGNUS. Type by tautonymy : Cygnm cygnus 

 (Linn.). 



Genus TADORNA. Type by tautonymy : Tadorna tadorna 

 (Linn.). 



Tadorna tadorna. For the reason of the change of this name 

 see Branta bernicla. 



Tadorna casarca. This Duck was named in Vroeg's Cata- 

 logue ; if this work were recognised it would stand as 

 Casarca ferntyinea. The Committee, however, have
