In the south Eustephanus galeritus has been seen flitting about the fuchsias of Tierra del Fuego in a snow-storm, and in the north-west Selatophorus rufus in summer visits the ribes-blossoms of Sitka, while in the north-east Trochilus colubris charms the vision of Canadians as it poises itself over the althaea-bushes in their gardens, and extends its range at least so far as lat.

Trochilus, trok′i-lus, n. a genus of humming-birds.

This unwieldy monster, having no flexible tongue wherewith to cleanse its mouth, comes on shore after its meals, opens its jaws, and allows the Tróchilus to enter and pick off the leeches and fragments of food, which, adhering to its teeth, interfere, with its comfort.
