To define the limits of the Paleearctic region in China is, with our 

 present knowledge, impossible ; and much of course depends on tem- 

 perature and local circumstances. From the observations of Mr. 

 Swinhoe and the Abbe David, however, it is clear that all the 

 northern part of the country belongs to it, as well as a great deal of 

 the mountainous country bordering on Thibet, in which a large pro- 

 portion of Himalayan forms will no doubt also be found. 



The list of birds from the province of Tchili, where for several 

 years the Abbe David has resided, gives me ample material for 

 showing this ; and though it does not agree in some points with Mr. 

 Swinhoe's revised ' Catalogue of Chinese Birds,' I think I may trust 

 it as being a faithful and fairly complete one. It includes 290 

 birds which have been observed by him at or near Pekin, 200 of 

 them being land birds ; of these there are : — 



per cent. 



European birds 65 32"5 



European genera, but not found out of Asia 



except as stragglers 105 52 - 5 



Genera not found in Europe 30 15 



Of the latter, some are birds of Northern or Central Asia, such 

 as : — 



Temenuchus dauricus. Syrrhaptes paradoxus. 



Erythrospiza mongolica. Crossoptilon mantchuricum. 



Uragus sibiricus. 



The rest are summer migrants from S.E. Asia, as : — 



Halcyon pileatus. Xanthopygia leucophrys. 



Chibia brevirostris. Myiophonus brevirostris. 



Dicrurus macrocercus. Zosterops erythropleurus. 



Buchanga leucogenys. Eurystomus orientalis. 



Tchitrea affinis. Nemoricola indica.

brevirostris. Tumix macidosa. 



Cyanoptila cyanomelana. 



Or residents of Himalayan type, as : — 



Pterorhinus davidi. Suthora webbiana. 



Abrornis armandi. Pucrasia .vanthospila.
