the pages embracing the tables of Orders and Families, as well as for the Grlos- 

 sary beginning on page 535 of VoL 111"— (Extract from Preface,) 



For the biographies of the species, the most prodnctive source of informa- 

 tion "has been the great amotmt of manuscript contained in the archives of 

 the Smithsonian Institution in the form of correspondence, elaborate reports, and 

 the field notes of collectors and travellers, the use of -which for the present work, 

 has been liberally allowed by Professor Henry. By far the most important of 

 these consist of notes made by the late Robert Kennicott in British America, 

 and received from him and other gentlemen in the Hudson Bay Territory, who 

 were brought into intimate relationship with the Smithsonian Institution through 

 Mr. Kennicott's efforts. . . . Equally serviceable has been the information re- 

 ceived from the region of the Yukon River and Alaska generally, including the 

 Aleutian Islands, . . ." — (Preface.) In elaborating these materials, Br. Brewer 

 further supplements his own knowledge with information derived from the pub- 

 lished notes of thenaturalists of the Pacific Rail road and other "Western Surveys, 

 and from the general literature of the subject, with less thorough digestion of 

 these materials than might be desired. 



It has apparently been deemed advisable, in a work of this character, to reduce 

 the synonymatic and bibliographical matter to Its lowest terms. 



The technical matter (diagnostic and descriptive) is based, and for the most 

 part derived, from Baird'b J3. JN". A., 1858, and Beview, 1864-66 ; the specific char- 

 acters, etc., being often directly transferred from those works to the present, with 

 such addition or modification as might be required. To this statement is to be 

 excepted the whole of Mr. Ridgway's extensive monograph of the Eaptores, and 

 Prof. Baird's article on Certhiola, which latter apparently represents a before 

 unpublished continuation of his IReview; with the further and principal excep- 

 tion of Mr. Ridgway's numerous elaborate analytical tables, which include, as 

 a rule, not only the N. Am. species, but also tbeir Cent, and S. Am. allies. 



The classification and general arrangement accord in the main with those 

 previously used by Baird ; but the nomenclature and details of the handling of 

 the birds are very different, numerous reputed species being reduced to "vari- 

 eties ", according to the prevalent views of what is sometimes called in Eng- 

 land the "American School". The result in this regard agrees more closely 

 with that exhibited in the present writer's Key of 1S72, Checklist of 1873, and 

 B.N. fT.of 1874. In addition to the variousnovelcombinations of generic, specific, 

 and varietal terms resulting from this, the following species or varieties are 

 named as new J but most of them were actually published previously by Mr. 

 Ridgw5.y in the Amer. Nat, vii, 1873, pp. 602-619, and Bull Essex Inst, v, 1873,
