the pampas to about fifty miles south of Buenos Aires. It is 

 almost invariably found in pairs throughout the year. 



In spite of its great weight (25 to 40 pounds) it rises quickly 

 by vigorous flapping, and if there be a breeze soon rises in 

 spirals like an Eagle and floats gracefully away. On the ground 

 they walk with a deliberate gait, recalling that of a Turkey-cock, 

 and they can swim well if forced to it, though they usually prefer 

 to use their wings. 



With regard to their breeding habits I could obtain little relia- 

 ble information from the natives, but I believe tney nest on the 

 ground in marshes and lay white eggs. 



One shot on December 11, iSSo, was standing in the edge of 

 tall grass on the border of a pool and did not see me until I fired. 

 He flew upward a few yards and then fell, and on picking him 

 up I found that he was ruptured across the abdomen so that the 

 bowels protruded in a large mass, evidently the result of the sud- 

 den eflbrt to rise. 



156. Chloephaga magellanica {Gm.). Ganso de la 

 SiEKRA (Mountain Goose). — Seen frequently at Carhu6 in 

 April, but not elsewhere. Probably a second species ( C. polio- 

 cephala Gray) was also seen, as the two species are usually found 

 together, but we took none. 



157. Cygnus nigricollis {Gm.'). Cisne (Sw-an). — This 

 species was noted in the salt 'laguna' Epecum, at Carhue, and 

 also at one or two other points on the pampas. I doubt if it ever 

 occurs at Concepcion, though another species ( C. coscorobd) 

 sometimes does, if the reports of the natives are to be credited. 



158. Querquedulacyanoptera ( K/ez7/.). Patito (Little 

 Duck). — This name is likewise given to the other species of 

 ^lerquedula., as well as to Erzsmatura. This is an abundant 

 species in the streams of the southern pampas in winter, but is 

 not found on the Uruguay, so far as I know. 



159. Querquedula brasiliensis (G?;?.). — This beautiful 

 bird is rather abundant at Concepcion during the cold weather, 

 and a few probably remain to breed, as I noticed a pair as late as 

 December 24, 1880. Unlike most of the other Ducks, it was not 

 often found in flocks, though occasionally a few would mingle 

 in flocks of other species. 



160. Querquedula flavirostris {Vici/l.). — Only seen on the 

 pampas, where it was one of the commoner Teal.
