STANLEY GOLDFINCH.

yellow, fading into white on the abdomen ; feathers on the throat black at 
the base ; lower tail-coverts yellow, tipped with white, and having a central 
dusky streak. Female dull yellowish-green above, faintly streaked with 
dusky, paler beneath. 
In this species, which I have named in honour of the illustrious Earl of 
Derby, the bill is so thick and short, as to approach in form to that of the 
European Greenfinch.
