out the original description of Ray before us, we are unable to say to which 

 of the two species his L. minor refers.

The preceding diagnosis is of a species, which, like the A. rufescens, is so 

 closely allied to the A. Unarms as to render it a matter of some doubt whether 

 it be anything more than a variety or race of that species. Its characters lie 

 in the somewhat larger size, and the very large bright yellow bill with its 

 short plumuli. Never having had an opportunity of examining a specimen of 

 this species, there being none in the Museum of the Smithsonian Institute, or 

 of the Philadelphia Academy, we can express no opinion with regard to its 

 relationships to the A. linaria. It is, we believe, admitted as a distinct species 

 by most later ornithologists, though Bonaparte and Schlegel, in their Mono- 

 graph of the Loxiince, place it in the same category as the A. rafescens. Having 

 nothing to offer respecting it, we take the liberty of transcribing the remarks 

 made by the authors just mentioned : 



" Cette racedu Sizerin resemble sous tous les rapports al'especeprecedente," 

 A. Unarms " mais elle est d'une taille plus forte, et son bee est plus long et 

 plus robuste. Elle est beaucoup plus rare que le Sizerin commun et la pe- 

 tite race appellee Cabaret ou Ac. rufescens. Nous avons examine un nombre 

 assez considerable d'individus pris en Saxe et en Belgique. On trouve quel- 

 quefois des individus intermedires entre cette race et le Sizerin, de sorte qu'il 

 existe entre ces oiseaux, un passage semblable a celui qui a lieu entre les 

 Bec-croises grand et ordinaire.") 



Temminck places this species (" HolbQU's Leinfink " of Brehm) as a syno- 

 nym of his Fringilla borealis. This, however, is an error, his F. borealis being 

 the Linaria canescens of Gould. 



We quote Linaria borealis Schleg. on the authority of Bonaparte's Conspectus. 

 It is, so far as we can learn, the only instance of the application of the name 

 borealis to this species. A discussion of Linota borealis Bp. will be found under 

 A. linarius.
