These birds with comparatively little blue on the outer 

 webs of the primary coverts, the outer secondaries and the 

 terminal half of the tail appear to belong to this western and 

 partially resident form which it is difficult to differentiate 

 with certainty as it is not improbable that some amount of 

 inter-breeding takes place. The subject has been dealt with 

 by Stresemann (Nov. Zool. XX, pp. 299-301 (1913)). There 

 appears to be little or no difference in size between the two 

 forms.

These birds are the brighter form with almost entirely 

 blue primary coverts and much blue on the tail and secon- 

 daries which is referred to this sub-species, known as a breed- 

 ing bird in the Eastern Himalayas and China.
