Dr. Adolf Doering, of the Argentine University of Cordoba, has been a zealous collector and observer of the birds of the Republic (see under Cabanis and Sclater). The zoological portion of his report upon the Rio Negro expedition of 1879 gives a list of the birds, which contains 110 species, most of them well-known Patagonian forms.

Durnford, Henry.

Henry Durnford, a member of the British Ornithologists’ Union, whose early decease was a severe loss to ornithological science, was a constant worker on birds from the time of his arrival in Buenos Ayres in 1875 until his death in 1878. The birds collected by Durnford are now mostly in the British Museum. His published papers on this subject are the following (see also biographical notice in ‘Ibis,’ 1879, p. 121):—

[Notes made during his first five months’ residence at Belgrano, five miles north-west of Buenos Ayres. About 70 species are mentioned.]

[Notes made principally at Baradero, 90 miles W.N.W. of Buenos Ayres. In the first paper 144 species are mentioned and Porzana spiloptera is described and figured as new. In the second 47 species, mostly additional, are noticed.]

[Durnford first visited Chupat, on the river of the same name, in Eastern Patagonia (43° 20′ S. lat.), in October 1876; 62 species of birds are noted and commented upon.]

[Durnford’s second visit to Chupat extended from September 1877 to April 1878. The list of birds is now extended to 89, and it is not believed that many more will be found to occur in the district.]

[This is an almost verbatim copy of Durnford’s journal in 1878, during his expedition to Tucuman and Salta. Many notes on birds are inserted. Durnford died at Campo Santo, in the province of Salta, on July 13th, 1878. The collection made on this occasion was worked out by Mr. Salvin (Ibis, 1880, p. 351, see below).]

Gibson, Ernest.

Mr. Ernest Gibson, who has been resident in the Argentine Republic since about 1873, is an excellent observer in the field, and has written two very interesting papers on our subject, from which we have quoted largely in this work.

Mr. Gibson’s notes, which relate to 61 species, are in most cases very full and contain particulars of the breeding-habits, eggs, and nests. Cape San Antonio is on the Atlantic coast, south of Buenos Ayres (36° 20′ S. lat.).

Field-notes on 52 species from this locality, which Mr. Gibson visited in 1883. The specimens were sent to Mr. J. J. Dalgleish and named by P. L. S.

Giebel, Prof. C. (of Halle, Germany).

In this paper the author described two new Bolivian species and two Argentine species (Troglodytes fasciolatus and Geobamon rufipennis), from specimens in the Halle Museum received from Dr. Burmeister.

Gould, John.

Gould determined the species in the collection made by Darwin during the voyage of the ‘Beagle,’ and drew up the scientific portion of the report on the birds, which forms vol. iii. of the “Zoology” of the voyage. Owing to his departure for Australia the MS. was subsequently completed and edited by G. R. Gray (see Darwin, C.).

Holmberg, Dr. E. L.

[Seventy-nine species of birds are given as occurring in the Sierra of Tandil, south of Buenos Ayres, and slight field-notes are added.]

Hudson, William Henry, C.M.Z.S.

My fellow-author of the present work, though English in name and origin and now resident in London, is an Argentine citizen by birth. From his early childhood he was an observer of bird-life in the province of Buenos Ayres, and continued his investigations until he left the country for England a few years ago. Besides the pampas he explored the woods and marshes along the Plata, and the range of the Sierras from Cape Corrientes on the Atlantic to the Azul and Tapalquen, and made an expedition to the Rio Negro in 1871.

The following is a list of his scientific papers on this subject, which are mostly incorporated in the present work:—

Lee, William Blackstone.

This article gives field-notes on seven species, of which examples were obtained near Frayle Muerto, in the province of Cordova, and 33 species from near Gualeguaychú in Entrerios. The specimens were determined by myself and Salvin.

Leybold, Dr. Friedrich.

Dr. Leybold was resident in Santiago, Chili, for some years, and sent bird-skins and other objects of natural history to Munich for sale in Europe. He published two papers on supposed new birds obtained by his collectors during their excursions from Chili to Mendoza.

[Describes as new Synallaxis crassirostris, Myiarchus fasciatus, Sporophila rufirostris, and Phrygilus ornatus, from Mendoza. These species are all referred to in our work.]

[This paper contains descriptions of Conurus glaucifrons, from San Luis (=Conurus acuticaudatus), Colaptes leucofrenatus (=Chrysoptilus cristatus), and Columbina aurisquamata (=Metriopelia aymara), all from Mendoza.]

Orbigny, Alcide d’.

After Azara’s ‘Apuntamientos’ this is the most important of the older publications relating to Argentine ornithology. The celebrated French traveller and naturalist d’Orbigny made extensive collections of birds in several parts of the Argentine Republic, especially in Corrientes, on the Paraná, near Buenos Ayres, and on the Rio Negro. The birds were worked out by himself after his return home, with the assistance of the well-known French ornithologist the Baron F. de la Fresnaye. The list of them, with the descriptions of the new species, was first published in two consecutive volumes of the ‘Magasin de Zoologie’ (for 1837 and 1838), with a separate title13 and separately paged. It was unfortunately never completed, and contains only the Accipitres, Passeres, and Picariæ. The valuable notes and remarks of d’Orbigny were subsequently published in the fourth volume of his ‘Voyage,’ of which the title is given above. This work also, as is much to be regretted, was brought to a sudden termination when only half finished.

D’Orbigny’s types are now mostly in the French National Collection at Paris, though a few of them, which cannot be found there, are supposed to have been retained in the De la Fresnaye Collection, and if so are now in the museum of the Boston Society of Natural History.

Page, Capt. T. J.

See Cassin, suprà, p. 223.

Salvin, Osbert.

The collection consisted of 84 specimens belonging to 54 species, obtained in June 1878 at Tucuman or near Salta. Nine were new to Dr. Burmeister’s list. See also Durnford, suprà, p. 224.

Schulz, Fritz.

Herr Fritz Schulz, an assistant in the museum of the University of Cordoba, brought a fine collection of birds to Europe in 1883, which he had made in Tucuman and other northern provinces of the Republic. The new species were described by Dr. Cabanis (see above, p. 223), except a single species described by Schulz himself.

[Describes Cnipolegus cabanisi from Tucuman.]

Sclater, P. L.

[The specimens were obtained near Buenos Ayres, where it is “not uncommon.” Dr. Burmeister also refers to Chlorostilbon phaethon.]

[Some of the specimens procured during Capt. Page’s expedition (see Cassin, suprà, p. 223) are remarked on. Of these Coryphistora alaudina is figured and Cnipolegus cinereus is described as new.]

[The specimen was shot by Hudson in the district of Quilmes, in April 1870.]

[The collection contained examples of nine species from the vicinity of Cordova.]

[Describes and figures Poospiza erythrophrys from Catamarca, and Synallaxis whitii from Oran.]

Sclater, P. L., and Salvin, O.

[This article gives a list of 98 species, determined from specimens sent to the Smithsonian Institution by Hudson.]

[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.]

[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 deplore14. 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:—

[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.]

[Contains remarks on 33 additional species, mostly from Cosquin, near Cordova. I added some notes, and described Poospiza whitii as new.]

[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.

Withington, Frank.

[Mr. Withington, for some years resident in Buenos Ayres, and an ardent collector and observer of its birds, has lately sent me a collection which contained examples of 92 species. His interesting field-notes are given in this paper.]
