Barrows on Birds of the Lower Uruguay. 
[April 
three small eggs taken from a nest of grass, etc., placed in a low 
bush. He gave a minute description of the bird, which he called 
“Jilguero,” and which could have been no other than the pres- 
ent species. The name “Jilguero” is only properly used for the 
Goldfinch ( Chrysomitris magellanica ) but any small black and 
yellow bird would receive this name for lack of a better. The 
eggs, now before me, are white with a faint creamy tinge and 
spotted at the larger end with chestnut, the spots on one egg being 
small and of pretty uniform size, and on the other two coarser 
with some large blotches: they average .8 2X^62 inch. The male 
has a pleasing song, much like a very subdued imitation of the 
warble of the Purple Finch (Carfodacus -purfiureus ) . 
10. Cyclorhis viridis ( VieilL ) . — This bird was frequently 
met with at Concepcion during spring and summer, being most 
abundant in July, August and September, but many doubtless 
remain through the summer and breed, though no nests were 
found. 
The bird’s favorite haunts seem to be the tangled thickets 
and low woods which border the streams and render so many 
of the river islands almost or quite impenetrable. Here, walled 
in by netted masses of jasmine, sarsaparilla, and passion flow- 
ers, there was little fear of interruption, and the male was often 
heard pouring forth his strong, clear warble with an energy 
which always suggested a bird of twice his size. 
11. Frogns chalybea ( Gm.) . Golondrina mayor (Lar- 
ger Swallow). — All the Swallows are known as “Golon- 
drinas,” and when it is desired to indicate a particular species an 
appropriate adjective is used 
The present species arrives at Concepcion from the north 
somewhat later than the smaller Swallows and is not so abun- 
dant, though its voice is usually to be heard at any hour of the 
day during the breeding season. 
During October and November the nests are built, — usually 
in hollows beneath the eaves of houses and sheds. Of the eggs 
I know nothing. 
On October 22, 1880, I spent nearly the whole afternoon in 
watching several hundreds of this species and Progne tafiera , 
catching dragon-flies. A high, cold, south wind (“pampero”) 
was blowing and the dragon-flies were massed by thousands on 
the leeward sides of the bushes near the top of a bluff. Benumbed
