Of the tongue, or mode of feeding of the bird at present before us, I can myself say nothing decisively, not having had leisure or opportunity, as I have already observed, of attending to the more interesting details of Natural History during the expedition.

But general opinion places this bird among the groups that feed by suction; and as I have a second species hitherto undescribed, which is closely allied to it, I prefer forming both provisionally into a new genus, to referring them to one, from which, although they agree with it in external appearance, they may be totally remote, in consequence of their internal anatomy and habits of life.

The error at least will not be so great, and may be easily retrieved.

If the tongue of my birds be found to accord with that of the Orioles, and not of the Honey-suckers, my group of course must fall.
