EDITORIAL NOTE. 



In 1904, the late D. G. Elliot published ' A Check-List of the Mam- 

 mals of the North American Continent, the West Indies, and the 

 Neighboring Seas.' 1 Shortly before his death he prepared the man- 

 uscript for a supplement to this work, carrying the subject to about 

 the end of the year 1914. On examination, at the request of his 

 daughter, Miss Margaret H. Elliot, this manuscript was found to be 

 practically ready for the press, and was submitted by her to the 

 authorities of the American Museum of Natural History for publica- 

 tion at her expense, under the auspices of the Museum, provided it 

 proved acceptable. It is here presented as written, with only such 

 revision and verification of references as the circumstances of posthu- 

 mous publication naturally require. 



The original edition of the Check-List gave fully the bibliographi- 

 cal references required in a modern check-list, together with the type 

 localities and geographic distribution of the forms included, and also 

 references to his previous works 2 where full descriptions of the forms 

 are given. The species and subspecies included in the Supplement 

 have for the most part been described since the publication of his 

 earlier works, on which the Check-List was based, and it was evidently 

 the author's intention to make this publication not only a supplement 

 to the Check-List, but a continuation of his preceding two manuals of 

 the subject, by giving descriptions of forms added as well as the usual 

 check-list matter. As known to his fellow-workers, it was his custom 

 to base his descriptions on the type specimens of the species and sub- 

 species involved, instead of compiling from the original descriptions. 

 For this reason the descriptive portion of this supplement is incom- 

 plete, in cases where the type specimens chance to be in foreign 

 museums or in the museums of the Pacific coast and Canada. De- 

 scriptions of some of the forms published in 1914 had also not been 

 completed, especially with reference to the measurements of the skulls. 

 The Editor regrets that it proved impracticable to have these blanks
