In both the ailull and young utagea of this (Joose the itluninge is so very distinct from that of U. hiiprrhoreiis that there is no (lerasiDU for confounding the two when the points of distinction are understood. We are uualde, however, to find tlie slightest difference in the details of form or in proportions â a fact wliich suggests the mere possilijlity of their be- ing white and colored phases of the same Hjiccies, as in some Herons ; but we do not consider this as at all probable, al- tliough in view of their similarity of fnrni and size, and that the chief variations area tendency toward partial albinism,* the possibility of such a relationship sliould be borne in mind. This form, once su])pose(l to be the young of the Snow Goose, is now regarded as au cntirt'ly good and dis'inct species.

The young of the hi/jterhoreuit arrive from the north with their parents without any intermixture of other (Jeese in their Hocks.
