specific identity of A. linarius and rufescens, says, that — 11 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- 
nyraes de mon Gros-bec sizerin ou Fringilla linaria des methodistes clearly 
mis-identifying Yieillot’s bird. In discussing Temminck's names of the Mgi- 
othi, it must be borne in mind that he sturdily refuses to admit the specific 
distinction of A. linarius and rufescens. He moreover places as a synonym of 
his Fringilla borealis , the “ Holbolls 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 - 
manni Holb. ; but as the name was previously applied by Yieillot to the A „ 
linarius , 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 Yieillot, is the A. Una- 
rms (Linn.) Cab. ; borealis Schlegel, is the A. Holbolli (Brehm) Cab. ; borealis 
Temminck, is the A. canescens (Gould) Cab.; while borealis u Ternm.” of Au- 
dubon is the A. exilipes Coues.
