Genus CHRYSOMITRIS, Boie, 1828. 



The genus Chrysomitris contains the Siskins, small birds of green 

 plumage closely allied in form to the Linnets. In this genus the 

 bill is very slender and pointed, but resembles that of the Linnets 

 so closely in general shape that it is unnecessary to figure it. In 

 the Siskins the sexes differ considerably in colour, the female being 

 streaked.
