88 Barrows on Birds of the Loxver 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 inageJlanicd) 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 .82X-62 inch. The male 

 has a pleasing song, much like a very subdued imitation of the 

 warble of the Purple Finch {Carpodacus purpurea s^ . 



10. Cyclorhis viridis ( V-ieilL). — 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. Progne 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 SwalloM's 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 33, 1880, I spent nearly the whole afternoon in 

 watching several hundreds of this species and Progne tapera^ 

 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
