subject are the following (see also biographical notice in ' Ibis ' 1879 

 p. 121):- 



(1) Ornithological Notes from the Neighbourhood of Buenos Ayres. Ibis, 



1876, p. 157. 



[Notes made during his first five mouths' residence at Belgrano, five 

 miles north-west of Buenos Ayres. About 70 species are mentioned.] 



(2) Notes on the Birds of the Province of Buenos Ayres. Ibis, 1877, p. 166, 



and 1878, p. 58. 



[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.] 



(3) Notes on some Birds observed in the Chupat Valley, Patagonia, and in 



the Neighbouring District. Ibis, 1877, p. 27. 



[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.] 



(4) Notes on the Birds of Central Patagonia. Ibis, 1878, p. 389. 

 [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.] 



(5) Last Expedition to Tucuman and Salta. Ibis, 1880, p. 411, pi. xii. 

 [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. 



(1) Ornithological Notes from the Neighbourhood of Cape San Antonio, 

 Buenos Ayres. Ibis, 1879, p. 405; 1880, pp. 1, 153. 



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 2<y S. lat.).
