•5 1 6 Barrows on Birds of the Lower Uruguay. [October 



seasons in a country which affords them a congenial cHmate and 

 an abundance of food. For a discussion of this matter from a 

 sportsman's point of view the reader is referred to an article by 

 W. Hapgood in 'Forest and Stream,' Vol. XVII, Oct. 20, 1881. 



197. Numenius borealis {Forst.'). — First seen at Concep- 

 cion, September 9, 1880, in large flocks. After the middle of Octo- 

 ber none were seen there, but after leaving Azul for Bahia Blanca 

 it was seen almost daily on the pampas in company with the Golden 

 Plover and Bartram's Sandpiper until late in February. After 

 March i none were met with. 



198. Sterna superciliaris Vieill. — A single female was 

 taken at Concepcion, October 14, 1880. 



199. Sterna magnirostris {Ltcht.). Gaviotita (Little 

 Gull). — A pair seen, and female taken, at Concepcion, Septem- 

 ber 9, 1880. They were following up a small sandy stream hunt- 

 ing like Kingfishers. 



200. Larus dominicanus ( }) Licht. Gaviota grande 

 (Big Gull). — A Gull about the size of our Herring Gull (Z. 

 argentatus) was abundant on the pampas during February 188 1, 

 and probably it was the same species which frequented the salt 

 'lagunas' at Puan and Carhue during March and April. As no 

 specimens were secured I refer it to dotninicanus with some 

 hesitation. 



201. Larus cirrhocephalus Vieill. Gaviota (Gull). 

 — Apparently i^esident at Buenos Aires, but only common at Con- 

 cepcion in winter. During May, June, and July, however, it was 

 common in iminense flocks, wheeling about the saladeros^ or 

 slaughter houses, alighting anywhere to pick up food, and usually 

 gathering in great companies at midday to sit preening their 

 feathers and gossiping for an hour or two in the sun on some 

 grassy spot well back from the river. 



Note. — No attempt is made to enumerate here the various 

 species of Gulls, Petrels, Shearwaters, etc, which abound in the 

 winter months at the mouth of the river, but which I had no op- 

 portunity of collecting or studying. 



202. .^chmophorus major {Bodd.). — Not uncommon at 

 Concepcion during cool weather, both on the river and on small- 

 er streams. My dates range from March 25 to September 26. 

 One, which I shot on June 29, had only long, fine, water-grass in 

 the stomach, not even the smell offish.
