SYNOPSIS OF THE BIRDS REPORTED TO INHABIT 



KAMTSCHATKA. 



The chief sources of our knowledge of the Kamtschatkan ornis are 

 the explorations of Steller, Vossnessenski, v. Kittlitz, Dybowski, and my- 

 self, but the localities from which reliable information has been gathered 

 are very few and limited, considering the area of the country, the greater 

 part of which is still a terra incognita. We know next to nothing about 

 the distribution of the species all along the western coast, and absolutely 

 nothing about the birds on the eastern side north of Nischnij Kam- 

 tschatka. We know very little, if anything, about the relations of the 

 two coasts of the peninsula inter se ; we do not know much more about 

 the birds of the mountains and their vertical distribution ; and we are 

 ignorant of the northern limits of most of the species. 



The following list, therefore, only attempts to enumerate the species 

 which have been recorded from Kamtschatka (including the Commander 

 Islands) without going into details. The figures in jjarenthesis following 

 the name refers to the page of this volume where the references belong- 

 ing to the species will be found. The other species are provided with 

 the necessary references. 



A few names, more or less generally credited to Kamtschatka with- 

 out there being any reliable authority for the statements, are given 

 without a number. 



COLTMBOIDE^. 



1. Colymbus holboellii (Reinh.) (p, 11). 



2. Colymbus auritus (Lin.) (p. 14). 



ALCOIDE^. 



3. Urinator adamsii (Gray) (p. 14). 



Whether U. imber also occurs is doubtful, but not improbable.
