360 APPENDIX. 



Motacilla boarula. Pallas' name M. melanope used in the 1st 

 edition of the List is of subsequent date (1776) to 

 Scopoli's, and refers to a slightly different eastern race 

 mentioned in the account of the distribution of the species. 



Motacilla flava thunbergi. Gmelin's name, M. viridis, used 

 in the 1st edition of the List, is founded on Brown's 

 plate (111. Zool. 1773, pi. 33. fig. 2), which is not 

 recognisable as a Wagtail. The next oldest name is 

 that of Billberg here used. 



Motacilla feldeggi. For this species Hartert and some other 

 authors use Motacilla melanocephala Lichtenstein, 1823. 

 But this name is invalidated by Gmelin's Motacilla 

 melanocephala, 1789, which now stands as Sylvia 

 mdanocepJiala, the Sardinian Warbler. 



Genus ANTHUS. Type by subsequent designation (Gray, 

 List Gen. Bds. 1st ed. 1840, p. 25): Anthus aquaticus 

 Bechst. = JL spinoletta (Linn.). 



Anthus spinoletta mbescens. Tunstall's name given in 1771, 

 founded on Pennant's Red Lark (' British Zoology,' 

 2nd ed. 1768-70, vol. ii. p. 239), antedates Latham's 

 pennsylvanicus of 1787, and Gmelin's ludowdanus, 1788. 

 All were originally founded on Edwards' " Lark from 

 Pensilvania" ('Gleanings/ ii. 1760, p. 185), which he 

 states was found " near London." 



Anthus petrosus. Latham's name Alauda olscura, dating 

 from 1790, is invalidated by Gmelin's Alauda obscura 

 (Syst. Nat. i. p. 801), dating from 1789. The earliest 

 valid name for the Rock-Pipit is therefore Montagu's 

 Alauda petrosa. 



Genus CERTHIA. Type by Linnean tautonymy and by subse- 

 quent designation of Gray (List Gen. Bds. 1st ed. 

 1840, p. 18) : C. familiaris. 



Genus TICHODROMA. Typo by monotypy : T. muraria 

 (Linn.).
