Carpodacus Kaup, Naturl. Syst., p. 161 (1829). Type, Carpodacus erythrinus Pall.
The genus Carpodacus is now often incorporated with Propasser but the differences in the two genera are constant and, as each genus contains a considerable number of species, it seems convenient and therefore wise to maintain them both.
Carpodacus differs from Propasser in having a longer and more pointed wing, the secondaries tailing short of the tip of the wing by a distance greater than the length of the tarsus, and in having no supercilium.
