Bill thick; second and third quills equal, first little shorter. Male with the upper part of the head black, the back and scapulars yellowish-green, faintly streaked with dusky, the rump inclining to greenish-yellow; the wings and tail black; the former, when extended, crossed by two bands, one greenish-yellow, tipping the first row of small coverts, the other bright yellow and broad at the base of the primary and secondary quills; tail also yellow in its basal third, except on the middle feather; lower parts greenish-yellow, feeding 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. _Male_, 4-9/12, wing, 2-10/12.
