APPENDIX III. 



Giving the reasons for the change of old names or for the- 

 non-adoption of changes which have been advocated by 

 recent authors, together with the method of fixation of the 

 types of the various genera used in the List. (See Intro- 

 duction, p. x.) 



Genus CORVUS. Type by Linnean tautonymy and by sub- 

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

 1840, p. 38) : C. corax Linn. 



Genus PICA. Type by tautonymy : P. pica (Linn.). 



Genus GARRULUS. Type by subsequent designation of Gray 

 (List Gen. Bds. 1st ed. 1840, p. 37) : G. glandarws 

 (Linn.). 



Genus NUCIFRAGA. Type by monotypy : [Nudfraga] 

 nudfraga Brisson = .ZV. caryocatactes (Linn.). 



Genus PYRRHOCORAX. Type by monotypy, " Choucas des 

 Alpes " of Buffon = P. gracidus Linn. 



Pyrrhocorax pyrrhocorax. There has been some doubt 

 about the correct names for the Cornish and Alpine 

 Choughs. In the 10th edition of Linnseus, Upupa 

 pyrrlwcorax is described, and although references 

 covering both the Cornish and Alpine Choughs are 

 given, the description " rostro pedibusque rubris " can 

 only refer to the Cornish bird. In 1766, in the 12th 

 edition, Linnseus seems to have altogether overlooked the 

 Cornish Chough, as the descriptions of Corvus pyrrlw- 

 corax and C. gracidus both seem to refer to the Alpine 

 Chough, and as the first of these names is preoccupied 

 by his description of the Cornish Chough in the 1758 

 edition, we must accept Corvus gracidus for the Alpine 

 Chough and C. pyrrliocorax for the Cornish Chough as 

 the correct names.
