Art. XXVI. — Third Instalment of American Orni- 

 tholog'ical Bibliog'raphy. 



By Dr. Elliott Coues, V. S. A. 



The Appendix to the Birds of the Colorado Valley (pp. 567[1]-784[218]), 

 which gives the titles of "Faunal Publications" relating to IS^orth 

 America, is to be considered as the Jirst instalment of this work. 



The second instalment occui^ies pp. 239-330 of this Bulletin, this Vol., 

 No. 2, and similarly gives the titles of '^ Faunal Publications", being 

 those relating to the rest of America. 



These two instalments represent all that I am at present i)repared to 

 publish of titles of this kind, i. e., in "regional'- Ornithology. 



This present, third instalment consists of an entirely different set of 

 titles, namely, those belonging to the "systematic" department of the 

 whole Bibliography. 



In this der>artment come the titles of all publications treating of par- 

 ticular species, genera, or families of Birds, sytematically arranged by 

 Families, in chronological order under each family, with alphabetization 

 of authors' names under each date. The lot of titles herewith presented, 

 however, are only those that relate to American species. Of those fam- 

 ilies which are exclusively American, as, for example, Mniotiltidw, Icte- 

 ridw, Tanagridcc, Trochilidw, etc., I give, of course, all the titles in my 

 possession; but of those families which are more cosmopolitan, as the 

 Turdidw or FringilUda', I select only the titles relatiug to American spe- 

 cies; and of extra-limital families no titles whatever are given. Such 

 is the ostensible scope of the j)resent instalment; but I actually give 

 many titles relating to extra-limital species, when the close relationship 

 of such apecies makes it desirable, or when the insertion of a few such 

 additional titles enables me to present all those that I possess of certain 

 families. 



The three instalments together represent a nearly complete Bibliog-
