It may be remarked that nearly all the Argentine members of this family belong to Antarctic forms, and are specifically different from those met with in North America. 335. BERNICLA MELANOPTERA (Eyton). (ANDEAN GOOSE.) +Chloëphaga melanoptera+, _Burm. La-Plata Reise_, ii. p. 513 (Cordilleras). +Bernicla melanoptera+, _Burm. P. Z. S._ 1872, p. 365; _Scl. et Salv. P. Z. S._ 1876, p. 362; _iid. Nomencl._ p. 128. _Description._--White; wing-feathers black; scapulars and tail greenish black; greater wing-coverts externally purplish, forming a speculum; smaller wing-coverts white; anterior scapulars spotted with brown, posterior scapulars brown with a greenish tinge: whole length 30·0 inches, wing 17·5, tail 6·5. _Female_ similar, but smaller. _Hab._ Andes of Peru, Bolivia, and Northern Chili. Dr. Burmeister met with this fine Goose on the Rio Blanco in the province of San Juan, within the confines of the Argentine Republic. It is an inhabitant of the high Andes of Peru and Bolivia, and is also found throughout the central provinces of Chili, descending to the plains in the winter. Its native name is "_Piuquen_," and it is said to be so abundant on a lagoon near the Portello Pass between Mendoza and Santiago that the spot is called "Valle de los Piuquenes." 336. BERNICLA DISPAR, Ph. et Landb. (BARRED UPLAND GOOSE.) +Bernicla dispar+, _Burmeister, P. Z. S._ 1872, p. 366 (Sierra Tinta, Rio Negro). +Bernicla antarctica+, _Burm.

Ibis_, 1878, p. 400 (Chupat). +Chloephaga magellanica+, _Barrows, Auk_, 1884, p. 273 (Carhué). _Description._--White; neck behind and body beneath banded with black; primaries, greater wing-coverts, tertiaries, and scapulars cinereous; rump and tail-feathers ashy black; bill black; feet dark plumbeous: whole length 26·0 inches, wing 16·0, tail 5·5. _Female_: head and neck cinnamon-brown; abdomen similar, passing into white on the crissum, and altogether barred with black; upper back also barred; rump and tail-feathers brownish black. _Hab._ Chili and Argentina. This bird is a northern form of the well-known "Upland Goose" of the Falkland Islands and Southern Patagonia, from which it differs in the male being completely barred across with black on the lower surface. It was first described by Philippi and Landbeck from Chilian specimens, and in 1872 recognized by Dr. Burmeister as found near the Sierra Tandil and on the Rio Negro.
