vermivora

from The Century Dictionary.

• noun A genus of birds, the American worm-eating warblers: now divided into several other genera, including Helmintherus (Helinaia or Helonæa) and Helminthophaga (or Helminthophila). (See warbler, swamp-warbler, and cut under Helminthophaga.) The name was applied by Lesson in 1831 to a different genus (of the family Tyrannidæ), and had been used by Meyer in 1822 in another sense.
