Note lanceolate — Family PSITTACIDÆ.—The Parrots. (continued 2)

The C. americanus has no analogue in Europe, though the C. corone somewhat resembles it. The most important feature of distinction appears to lie in the structure of the feathers of the head and neck, which in C. corone are narrow, with the tips distinct, while in the American bird these tips are blended together and do not maintain their individuality. The feathers on the fore-neck in corone are also lanceolate and distinct, showing the outline of each one as in the Raven, while in the American Crow they are three times as broad, rounded, and entirely blended. Mr. Audubon further remarks that the neck of the European bird is glossed with green and blue, while that of the American has a decided purplish-brown tinge.
