ADDITIONS AND CORRECTIONS TO THE 



HAND-LIST OF BRITISH BIRDS. 

 (THIRD LIST) 



BY 



THE AUTHORS. 



The following additions and corrections to our Hand-List of 

 British Birds (1912) are additional to those in the two Usts 

 already published (see Brit. B., IX., pp. 2-10, XL, pp. 2-5). 

 It should be remarked that these hsts refer only to nomen- 

 clatural revisions and to species or subspecies added to the 

 hst since the publication of the Hand-List. No attempt has 

 been made to include additional records or revisions of 

 distribution, for which A Practical Handbook of British Birds 

 (now in course of publication) should be consulted. 



Add— 



13a. Sturnus vulgaris zetlandicus Hart. — THE SHET- 

 LAND STARLING. 



Sturnus vulgaris zetlandicus Hartert, Nov. Zool., XXV., 

 p. 329 (1918 — Shetland Islands. Type : North Yell). 



For further remarks on this form compare Bull. B.O.C., 

 XXXIII. , pp. 63-4, Scott. Nat., 1915, pp. 3-4, and Brit. Birds, 

 XII., pp. 207-8 and A Practical Handbook of British Birds, 

 p. vi. 



117. Muscicapa albicollis Temminck. 



MuscicAPAALBicoLLisTemminck,Man.d'Orn.,p. 100 (1815 — ). 

 instead of Muscicapa collar is Bechstein. 



Bechstein's M. collaris of 1795 is preoccupied by Latham's 

 M. collaris of 1790, which referred to an African bird. The 

 next available name for the Collared Flycatcher must therefore 

 be used. The Rules of Nomenclature demand this alteration, 

 and the principle "Once a synonym always a synonym " 

 must be scrupulously accepted. 



127. Phylloscopus humei praemium Math. & Ire. 



Phylloscopus humei premium Mathews and Iredale, Austral 



Av. Rec, III., p. 44 (1915 — Russia), 

 instead of Phylloscopus superciliosus superciliosus (Gm.). 



Motacilla superciliosa Gmelin 1789 was preoccupied by the 

 use of the same name in 1783 by Boddaert for an American 

 Warbler, and Gmelin's name cannot therefore be used for the 

 Yellow-browed Warbler, for the same reason as explained 

 above under Muscicapa albicollis.
