Distribution of Birds. 547 



was able to persuade him to revise these notes, and with his 

 assistance to republish them in the work which we called 

 '^ Argentine Ornithology' (120). These two volumes contain, I 

 believe, a tolerably complete account of 434 species which 

 we referred to the Argentine Ornis. I can claim little credit to 

 myself for this undertaking, except that of having rescued 

 from oblivion and reduced into systematic form my fellow- 

 worker's excellent field-notes. 



As regards the southern portion of the Patagonian Region 

 no great progress has been made of late years, though several 

 publications have appeared which bear more or less upon 

 the subject (121, 1 22) . The same is nearly the case with the 

 Trans-Andean portion of the Patagonian Subregion, which 

 lies mainly within the confines of the Republic of Chili. 

 Here, however, we have a modern list of the birds of Chili, 

 compiled by Mr. H. B. James, F.Z.S. (123). The same 

 gentleman has further shown his interest in Chilian orni- 

 thology by employing several collectors, the results of whose 

 work I have had the pleasure of examining. I have thus 

 been enabled to make some contributions towards our 

 knowledge of the previously almost unknown ornis of the 

 Province of Tarapaca (124, 125), which has of late years 

 become a portion of the Chilian Republic. 



Conclusion. 



Having now reviewed the principal additions that have 

 been made to the literature of Geographical Ornithology 

 since I performed the same task in my Address to the 

 British Association at Bristol in 1875, I hope that my 

 fellow-workers in ornithology will allow me to offer a few 

 remarks upon what I consider to be the special requirements 

 in this branch of our science most pressing at the present 

 moment. Where so much remains to be done it is of course 

 difiicult to make a satisfactory selection, but I venture to 

 point out the following seven pieces of work as specially 

 calling for attention : —
