In the above lists there are rather more Oriental than Palee- 

 arctic genera ; but it must be remembered that most of the 

 former are summer migrants only, or stragglers just entering the 

 sub-region ; whereas the great majority of the latter are per- 

 manent residents, and a large proportion of them range over the 

 greater part of the Manchurian district. Many of those in the 

 Oriental column should perhaps be omitted, as we have no exact 

 determination of their range, and the limits of the regions are 

 very uncertain. It must be remembered, too, that the Palsearctic 

 genera of Sylviida?, Paridae, and Fringillidae, are often represented 

 by numerous species, whereas the corresponding Oriental genera 

 have for the most part only single species ; and we shall then 

 find that, except towards the borders of the Oriental region the 

 Palsearctic element is strongly predominant. Four of the more 

 especially Oriental groups are confined to Japan, the southern
