Callacanthis Reichenb., Syst. Av., tab. lxxviii, fig. 12 (1850). Type, Callacanthis burtoni Gould.
The genus Callacanthis has affinities both with the Rose-Finches and Goldfinches. The bill is shaped like that of Carduelis but is much stouter and both wide and deep at the base : the wings and tail are white-spotted somewhat as in those of the Goldfinch and the male has some scarlet on the face; on the other hand, the whole lower surface is washed with red-crimson. The wings are very long and the sexes are not alike.
