CONTRIBUTIONS TO THE ORNIS OF ÖAGHALIN. 67 



As may be seen from the foregoing list, about 177 different 

 birds have been recorded from the island of Saghalin. Our 

 knowledge of its ornis is no doubt still incomplete, but at least 

 99 of the species may be regarded as regular breeders. This 

 number will probably be augmented by a good many more. To 

 state any definite numbers is still too early, but this much may 

 be said that by far the greater number, about 709^ roughly 

 speaking, of the breeding birds of Saghalin are found not only 

 in the adjacent parts of the continent but also in Yesso. About 

 15^0 of the same are found on the continent and not in Yesso ; 

 and about 109^ are found in the latter island but not on the 

 continent, while some few subspecies are endemic. About 

 one half of the breeders have been recorded from the Kurile 

 Islands as well. About one third of the birds breeding in 

 Saghalin has a very wide distribution over the whole Palneartic 

 region, some being even circumpolar. 



With Kamtschatka Saghalin has about a hundred species of 

 birds in common, ^^ but not one half of these are as yet known 

 to breed in Saghalin. Of the breeders common to both 

 countries, about half the number belongs to the group which 

 Stejneger has termed " East Asiatic ", that is such as " do not 

 occur west of the Jenisei River " ; about one fourth or a little 

 more is distributed over the entire palsearctic region ; not quite 

 as many are circumpolar and about one-eighth may be termed 

 *' Pacific ". To the last group belong chiefly the members of the 

 Alcidœ. 



As already alluded to above, our knowledge about the Ornis 

 of Saghalin, although greatly widened by Prof. Ijima's Expedition,
