givenby Fabricius as a bird of Greenland, but stated by Holboll to have been theyoung of F. anatum, and Butco vulgaris and Hypotriorchis wsalo7i, both ofwhich are also European species, and have never been found in America toour knowledge, though there are species which are nearly related to them. The student may advantageously bear in mind that of those above, whichwere originally described by Pennant, in English, abstracts or compilationsonly, in Latin, are given by Gmelin in his edition of the Systema Natura ofLinnseus. These abstracts are mostly very short, and not always to berelied on as conveying strictly the sense of the originals.

Nor is this alEnity restricted, apparently, to any oneclass, or to such as might have migrated, but is found to exist in a greater orless degree in classes of animals, as that of reptiles, possessing powers oflocomotion too limited to admit of such supposition. When, too, we havehad our attention directed to the family of Sparrows and Finches, to thebeautiful Jays and Magpies, or the various species of Grouse, Partridges, andmany other families, we have been almost persuaded to entertain the opinionthat the birds of Western America are of a hig
