ART. 15 BIEDS COLLECTED IN" CENTKAL CHINA RILEY O 



I refer these specimens to the eastern race with some hesitancy. 

 They are much lighter in color, especially below, but they seem 

 nearer to it than they do to the race occurring in Yunnan and western 

 Szechwan (A. p. Jiaringtoni) . From the latter they differ in being 

 also lighter, especially below, and lack entirely or almost so, the paler 

 edges to the feathers of the mantle. When a larger and better pre- 

 pared series is available, it may be necessary to separate the bird 

 occurring in the arid desert country from that from the coast.
