Linaria, Selby. 



Borealis, Vieill. 

 Does not appear to differ from Fringilla in any respect except in size, 



Carduelis, Briss. 



Elegans, Steph. 

 Similar to the last. 



Chrysomitris, Boie.

 There is a very slight difference in form between this genus and Carductis ; the 

 intermaxillary bones are smaller in the former than in the latter. The os furcatum is 

 longer in Fringilla, in proportion to size, than in Chrysomitris.
