city; and I observed it last year, when we had unusually severe 

 weather, within thirty miles of Buenos Ayres ', it rarely, 

 however, comes as far north as this. 



98. Cygnus nigricollis (Gm.) ; Scl. et Salv. P. Z. S. 1868, 

 p. 145. 



Winter visitor, but the time of its arrival and departure 

 very uncertain, depending chiefly on the mildness or severity 

 of the season. This has been a very mild winter, and com- 

 paratively few Wildfowl have visited us. This time last year, 

 22nd July, the market was well supplied with Swans and 

 Ducks ; but the gunners have had a bad time of it this year. 

 Common at Baradero in April. 



99. Cygnus coscoroba (MoL); Scl. et Salvin, P. Z. S. 1876, 

 p. 371. 



Winter visitor, like the preceding ; and, like that bird, few 

 have come this year. 



100. QUERQUEDULA FLAVIROSTRIS (ViciU.) J Scl. Ct Salv. 



p. Z. S. 1868, p. 146. 



A few breed here; but the majority of those obtained in 

 the winter are visitors from the south. This and the follow- 

 ing species have very much the habits of our little Teal at 

 home — when flushed, following the course of the stream and 

 dropping suddenly. Iris wood-brown. 



101. QuERQUEDULA CYANOPTERA (Vicill.) ; Scl. Ct Salv. 



p. Z. S. 1869, p. 160. 



Pretty common in the winter, a few breeding here. Fre- 

 quents the same situations as the two last-named species, 

 small pools and watercourses, but not generally found in the 

 large lagunas. Common at Baradero in April. Iris scarlet, 

 with a tinge of carmine ; legs and feet bright orange. 



102. QuERQUEDULA VERSICOLOR (Vieill.) ; Scl. et Salv. 

 P. Z. S. 1868, p. 146. 



Very common, many breeding in the neighbourhood. Com- 

 mon at Baradero in April. Flocks of this species do not mix 

 with those of any other ; but their flight and habits are similar 

 to those of Q. flavirostris . Iris wood-brown.
