[This article contains the results of an examination of a second collection from the same locality, likewise belonging to the Smithsonian Institution, and adds 14 species to the former list. It also gives an account of a collection made by Mr. Haslehurst near Buenos Ayres, which contains examples of 10 species not up to that date transmitted by Hudson.] (3) Third List of Birds collected at Conchitas, Arg. Rep., by Mr. W. H. Hudson. P. Z. S. 1869, p. 631. [Hudson's third collection sent to the Smithsonian Institution contained examples of 92 species, of which 33 were additional to those contained in the two former lists. Thus the total number of species of the district of Quilmes is raised to 143.] WEISSHAUPT, ALBERT. Herr Weisshaupt was a German collector at Santiago, Chili, who came several times to London with fine collections of living animals (see P. Z. S. 1870, p. 664, and 1871, p. 700). He made one or more excursions to Mendoza from Santiago, and collected bird-skins in the vicinity of that city. Many of these skins were acquired by Messrs. Salvin and Godman and myself respectively and are in our collections. WHITE, ERNEST WILLIAM. Ernest William White was another active worker in Argentine ornithology, whose untimely death we have lately had occasion to deplore[14]. During five years' journeyings in the northern provinces of the Republic White made very extensive collections and accumulated a mass of excellent notes, which are published in the following papers:-- [14] For biographical notice of this naturalist see Ibis, 1885, p. 335. (1) Notes on Birds collected in the Argentine Republic. With Notes by P. L. Sclater, M.A., Ph.D., F.R.S. P. Z. S. 1882, p. 591. [This article contains field-notes on 201 species from various provinces of Argentina, including Misiones and Oran. The species were mostly determined by me, and I added some remarks.] (2) Supplementary Notes on the Birds of the Argentine Republic. With Remarks by P. L. Sclater. P. Z. S. 1883, p. 37. [Contains remarks on 33 additional species, mostly from Cosquin, near Cordova. I added some notes, and described _Poospiza whitii_ as new.] (3) Further Notes on the Birds of the Argentine Republic. P. Z. S. 1883, p. 432. [Gives the names of and notes upon 19 additional species, determined by comparison of specimens with those in my collection and that of Messrs. Salvin and Godman.] Mr. White's 'Cameos from the Silverland' (2 vols., London, 1881-82) should likewise be carefully studied by those who wish to become acquainted with the natural history of the Argentine Republic.
