ADDITIONS AND CORRECTIONS TO THE 



HAND-LIST OF BRITISH BIRDS. 

 (FOURTH LIST) * 



BY 



THE AUTHORS. 



An important list of alterations to the B.O.U. List published 

 in the Ibis (April 1921) has, we are glad to say, made that 

 list as amended almost uniform, so far as nomenclatorial 

 questions are concerned, with our Hand-List as amended, 

 and, so far as published, with the Practical Handbook. This is 

 certainly a step in advance towards the uniformity in nomen- 

 clature for which we have worked. In this B.O.U. List of 

 alterations the nomina conservanda are to be discarded and the 

 names in Vroeg's Catalogue are to be accepted, these decisions 

 having the effect of making twenty names which formerly 

 differed in the two lists the same as those in our Hand-List. 

 It is also proposed to adopt Erolia for the " Stints " and 

 Tringa for the Sandpipers, etc., as used by us. The con- 

 clusion, however, is reached that Calidris is the correct generic 

 name for the Knot. As Calidris was published in 1804 and 

 Erolia in 1816 this would mean that Calidris would have 

 to be used for the " Stints " unless the Knot were separated 

 generically. In the Hand-List this was done, but in British 

 Birds, Vol. XL, p. 4, we pointed out that there was no justi- 

 fication for this separation. We are still of this opinion, but 

 solely for the sake of uniformity we propose to be inconsistent 

 and to separate the Knot generically and thus retain the genus 

 Erolia for the " Stints." 

 The following are the alterations and additions : — 



For genus Hypolais, Nos. 141, 142 and 142a, of the Hand- 

 List, and Vol. I., p. 351 of the Practical Handbook, substitute 

 Hippolais Baldenstein, Neue Alpina, IL,p.27 (1827 — Mono- 

 type H. italica Bald. — H. polyglotta (Vieill.) (See Ibis, 1921, 

 p. 312, and Austral Av. Rec, III., p. 122). 



222. Athene noctua mira Witherby. 



Athene noctua mira Witherby, Brit. B., XIII., p. 283
