have described most of the novelties not previously named by Butur- 

 lin. The latter spent some time near the mouth of the Kolyma and 

 made large collections there but has published no connected account 

 of his work, to my knowledge, though in his paper on the Rosy Gull ^ 

 a good description of the country is given and many species of birds 

 are mentioned. 



Thayer and Bangs's list is so well done that little can be. added to 

 what they have already said, but as Mr. Amory seems to have reached 

 a higher point on the Kolyma than Koren did on his previous trip, 

 he naturally secured a number of forms not obtained by the latter, 

 and it has been thought advisable to publish this list, with the field 

 notes of the collector, as a supplementary contribution to the orni- 

 thology of a little-known region. 



For convenience of comparison the species are listed in the order 

 followed by Thayer and Bangs. 



The author is indebted to the authorities of the Museum of Com- 

 parative Zoology for the loan of a series of Phylloscopiis trochilus 

 eversmarmi for comparison.

1. LAGOPUS LAGOPUS KORENI Thayer and Bangs.= 



Seventeen specimens from the following localities: Annuj River, 

 September 12, 18, and 23, 1914; Little Annuj River, September 23, 

 November 9, and 26, 1914; Nijni Kolymsk, January 20, February 11, 

 and June 12, 1915 ; Verkhni Kolymsk, April 12, 17 and 20, 1915 ; 7 

 miles north of Nijni Kolymsk, May 19, 1915 ; 30 and 33 miles west 

 of Verkhni Kolymsk, May 23, 1915 ; Kolyma Delta, July 11, 1915. 



This series bears out the characters ascribed to it by the describers, 

 and to their account I can add nothing. In measurements it comes 

 very close to Lagopus I. ungavus as the following table will show:
