they go in the summer I do not know, but they were abundant at 

 Carhu6 and neighboring pUices in March and April. 



193. Totanus melanoleucus {Gm.). Chorlo (Plover). 

 — Occurs sparingly at Conccpcion every month in the year, but 

 in increased numbers during August, September, October and 

 November. 



Birds taken during August and September were for the most 

 part in worn plumage and quite thin ; those taken at other times 

 seemed to be in much better condition ; but I never found any 

 which showed evidence of any nearness to the breeding season. 

 1 believe that part of these are birds bred in North America, and 

 the rest ai"e natives of the southern pampas of Patagonia. They 

 were abundant at x\zul, January 25 to 31 ; at Bahia Blanca one 

 was seen on February S ; I heard them at Puan March 28, and 

 they were numerous at Carhu(5 the first week in April. 



194. Totanus flavipes {Gm.). — Usually noted with the 

 preceding, hut none were seen at Concepcion during May, June, 

 and July, 18S0. At Azul they were quite plenty January 28, 

 iSSi. 



195. Rhyacophilus solitarius {Wlls.). — In parties of two 

 to six at Concepcion during August, September, and October. 

 First seen there August 20, 1880. I saw a few between Buenos 

 Aires and Azul on January 35, 1881. 



196. Actiturus bartramius {Wils.). — A common bird 

 everywhere from November to April. Especially abundant 

 about the vast swarms of 'locusts' which were sweeping the coun- 

 try in 1879 and iSSo. During December, 1880, I frequently saw 

 thousands of the birds in the compass of a very few acres. They 

 were all in rather poor plumage, but many of them quite fat. In 

 habits they were precisely like the same birds here, except that I 

 several times saw single birds balancing themselves for a few 

 seconds on the tops of bushes, which I do not remember noting 

 before. That this species regularly ranges from the United 

 States to the pampas I no longer have any doubt. The same mav 

 be said of the last three species mentioned and the one following, 

 with this single difference, that while I am pretty well satisfied 

 that some individuals of Totanus melanoleumcs breed on the 

 pampas or in Patagonia, I found no evidence that any of the other 

 species mentioned do so. They seem to be simply visitors from 

 the northern hemisphere, spending the time between breeding-
