Show 1876.] NEOTROPICAL ANATIDvE. 363 This fine goose is found in the high Andes of Peru and Bolivia, and has been observed both on Lake Titicaca and at Tinta and Pi-tumarca, at an elevation of from 11,000 to 14,000 feet above the sea-level, in what Tschudi has termed the " Puna region." It is also found throughout the central provinces of Chili, descending to the plains in winter, but in summer retiring to the high Cordillera, to the verge of the line of perpetual snow. It has been observed at Quintero, in the province of Santiago, and in such numbers, on a small body of water near the celebrated Portillo Pass, that the spot is called Valle de los Pinquenes, Pinquen being the native name of this species. The limit of its southern range probably hardly passes the 35th degree of south latitude. There were three specimens of this fine species lately living in the menagerie of this Society (List Vert. Zool. Soc. 1872, p. 244) ; but none of them seemed to enjoy such good health in captivity as the other South-American Geese. The male is considerably larger than the female. 3. BERNICLA MAGELLANICA.
