The preponderance of East Asiatic and peculiar forms, both on the 

 whole, and especially in those groups which are of most value for the 

 study of the geographical distribution, is clearly demonstrated by this 

 table. We are, therefore, justified in taking the birds contained in this 

 category as a basis in attempting an analysis of the Kamtschatkan ornis, 

 and a comparison of it with that of adjacent countries. 



Eeferring to Table VII, page 338, for an enumeration of the species, the 

 geographical relations of which we are going to discuss here, we may at 

 once tabulate those forms which we regard as peculiar to the peninsula. 



Table XIII.— Species peculiar to Kamtschatka. 



Urogallus parvirostris kamtschaticus. 

 Astur candidissimus. 

 Haliseetus hypoleucus. 

 Dryobates purus. 



immaculatus. 



Picoides albidior. 



Pica camtschatica. 



Pyrrhvila pyirliula karatschatkensis. 



Parus kamtscliatkensis. 



Sitta albifrons. 



It will be seen that this enumeration only comprises residents and none 

 of the several migr.tory birds which have not yet been reported from 

 any other country, or which breed nowhere except in Kamtschatka. 

 Some one might urge that a species which only breeds in Kamtschatka 

 is peculiar to that country. This is true to a certain degree, but our 

 knowledge of the localities where many or most of the species in ques- 

 tion brcQd, or do not breed, is at present so imperfect as to make the 

 above selection advisable. 



The other residents (the exact number of which, as compared with 

 that of the migrants, cannot be ascertained at present), are nearly all 

 Circumpolar or Pal^arctic species of wide distribution. Most of these 

 are species which retain a great uniformity all over their enormous 

 range, except a few ones, for instance, Coccothraustes, Parus ater, .^gi-
