The Appendix to the "Birds of the Colorado Valley" (pp. 567 [l]-784 

 [218]), which gives the titles of "Faimal Publications" relating to North 

 American Birds, is to be considered as the first instalment of a "Uni- 

 versal Bibliography of Ornithology ". 



The second instalment occupies pp. 239-330 of the " Bulletin of the 

 United States Geological and Geographical Survey of the Territories", 

 Vol. V, j^o. 2, Sept. 6, 1879, and similarly gives the titles of " Faunal 

 Publications" relating to the Birds of the rest of America. 



The third instalment, which occupies the same "Bulletin", same Vol., 

 No. 4 (in press), consists of an entirely different set of titles, being those 

 belonging to the "systematic" department of the whole Bibliography, 

 in so far as America is concerned. Here come the titles of all publica- 

 tions relatuig to particular species, genera, or families of American Birds, 

 systematically arranged, hy families^ and in chronological ordei'. 



These three previous instalments represent a nearly complete Bibli- 

 ography of American Ornithology. 



This present, /o?fr^/<, instalment of the work is of the same character 

 as the first two: that is, it relates to "regional" or "faunal" as distin- 

 guished from "systematic" ornithology; and it undertakes to do for 

 British Birds what the first two did for American. 



That is to say: here belong the titles of all publi(;ations treating- of 

 Britisli Birds as such, exclusively, and indiscriminately or collectively. 

 In publishing these preliminary instalments, it is necessary to draw a 

 hard and fast line between those titles which are and those wliich are 

 not to be found in each one of them — a line wliich wonld be very evident 

 to one cognizant of the plan of the whole bibliography, though by no 

 means obvious at first sight. It is therefore lu'cessary tor iiu> to bo 

 explicit here. j
