specific identity of A. Unarms and rufescens, says, that " le Sizerin boreal 

 (Linaria borealis) de Vieillot forme une espece distincte" from A. rufescens 

 " identique de mon Gros-bec boreal de l'article precedent, mais auquel on ne 

 doit pas reunir le Sizerin ou le Cabaret des auteurs, deux denominations syno- 

 nymes de mon Gros-bec sizerin ou Fringilla linaria des methodistes ;" clearly 

 mis-identifying Vieillot's bird. In discussing Temminck's names of the jEgi- 

 othi, it must be borne in mind that he sturdily refuses to admit the specific 

 distinction of A. Unarms and rufescens. He moreover places as a synonym of 

 his Fringilla borealis, the " Holbolla Leinfink" of Brehm., which later orni- 

 thologists, with what propriety I am unable to say, regard as a distinct 

 species. 



Borealis of Temminck has priority over both canescens Gould, and Horne- 

 rianni Holb. ; but as the name was previously applied by Vieillot to the A. 

 Unarms, it cannot of course be retained. 



This name borealis has been applied by four authors to as many different 

 species, for neither of which it can stand. Borealis Vieillot, is the A. Una- 

 nus (Linn.) Cab. ; borealis Schlegel, is the A. Holbolli (Brehm) Cab. ; borealis 

 Temminck, is the A. canescens (Gould) Cab.; while borealis "Temm." of Au- 

 dubon is the A. exilipcs Coues.
