APPENDIX. 371 



Accentor modularis. Hartert (Brifc. Birds, iii. 1910, p. 313) 

 separates the British breeding race of the Hedge- 

 Sparrow as distinct under the name of Prunella modu- 

 laris occidentalis. The Committee, after careful exami- 

 nation, have been unable to recognise the differences 

 between the British and continental races. 



Genus CINCLUS. Type by monotypy : C. cinclus (Linn.). 



Cinclus cinclus. The earliest name for this, the Swedish race 

 of the Dipper, is that of Linnaeus. In the 1st edition 

 of the List it was entered as C. melanogaster Brehm 

 to avoid using the same generic and specific names. 

 Cinclus aquaticus Bechst., the name used tor the British 

 Dipper in the 1st edition of the List, should be applied 

 to the Dipper of central Europe, which is now con- 

 sidered to be a distinct subspecies. 



Genus TROGLODYTES. Type by subsequent designation of 

 Baird (Pacific R. R. Reports, ix. 1858, p. 367) : T. aedon 

 Vieill. Gray (List Gen. Bds. 1st ed. 1840, p. 10) desig- 

 nated T. europceus = T. troglodytes, a species not men- 

 tioned by Vieillot in his original description of the genus. 



Genus MUSCICAPA. Type by subsequent designation of 

 Gray (List Gen. Bds. 1st ed. 1840, p. 32) : J/. grisola. 



Muscicapa grisola and M. atricapilla. If Vroeg's Catalogue, 

 published in 1764, were recognised, the Spotted and Pied 

 Flycatchers would be known as M. striata and M. liypo- 

 leuca respectively. See Sylvia subalpina, p. 303. 



Genus HIRUNDO. The type of this Linnean genus h;is 

 always been a somewhat difficult question to decide. 

 The genus contains eight species, of which the first- 

 named is " rustica,'' the Swallow, and this was made 

 the type of the genus by Gray (List Gen. Bds. 1st ed. 

 1840, p. 8), and adopted as such by Sharpe in the Cat. 

 Birds B. M. (vol. x. 1885, p. 123) and by the A. 0. U. 

 Check-List.
