The next natural section is that of Saucerottia, of which I am acquainted with three species distinguished from the Erythronotæ by their larger size, stouter bills, and by their more uniform dark-green colouring. All are confined to a comparatively limited area—namely, Costa Rica, Veragua, Panama, and the northern parts of New Granada.
Saucerottia typica (Bonap.)
Habitat: New GranadaPlate 321 Erythronota Saucerottei Saucerotte’s Erythonote
Habitat: Costa Rica, Veragua, and New GranadaPlate 322 Erythronota Sophiæ Sophia’s Erythonote
Habitat: Banks of the River Magdalena
As the S. Sophiæ differs from the S. typica in the richer blue colouring of its upper and under tail-coverts and tail, so does this species differ from the S. Sophiæ in having the tail and its coverts both above and beneath of a still richer and more violet blue. It is also of smaller size; and the green of its under surface is different from that of both, being purer and deeper. The examples in my collection were obtained by M. Warszewicz on the banks of the Magdalena.
