and back, and white. Loral region snuff-brown. Sides of head and 

 face white, much shaded with snuff-brown.

Geographical Range. — Falkland Islands, Tierra del Fuego, the Straits 

 of Magellan and both the coast and interior of Patagonia, reaching into 

 Southern Argentina. 



The naturalists of the Princeton Expeditions saw this fine Upland Goose 

 frequently during their travels and the pair cited in full above, the three 

 young and an adult male from the Museo de La Plata, form the material 

 for the descriptions given here. 



Dr. Robert O. Cunningham says of these geese: "This species, the 

 Upland goose [Chloephaga magellanica) is very plentiful in the eastern 

 portion of the Strait of Magellan, but is very seldom to be seen much to the 

 west of Port Famine. It is also very abundant at the Falkland Islands, 

 and is common on the lower slopes of the Chilian Andes. In the Strait 

 of Magellan it breeds in numbers, on Elizabeth, Sta. Magdalena, and 

 Quartermaster islands. The plumage of both male and female birds, as 

 all those who have had an opportunity of seeing them in the Zoological 

 Society's Gardens will, I think, agree with me, is very handsome — that 

 of the male being white, with narrow black transverse bars on the feathers 

 of the back and breast ; while that of the female is chiefly composed of 

 various shades of brown, the feathers being also barred with black. Mr. 

 Darwin, in his notes on this species, remarks that 'at the Falkland Islands 

 they live in pairs and in small flocks throughout the island, being rarely 

 or never found on the sea-coast, and seldom even near fresh-water lakes ' 

 — an observation from which my experience widely differs, as I never 

 saw them either at the Falkland Islands or in the Strait, at any consider- 

 able distance from the sea ; and I frequently observed them on the banks 

 of small lakes of salt and fresh water." Possibly this discrepancy may 

 have resulted from their having been noticed at different periods of the 

 year. 



"The first pair of 'Upland Geese' were acquired from Governor Moore, 

 of the Falkland Islands, in 1857; and a second pair was received in 1861. 

 The first young birds were hatched in 1863; and the species has since 

 bred with us with tolerable regularity, as will be seen by the following list.
