Wing 483 mm. The white on the inner web at the base 

 of the primaries rather well developed. 



This species is not recorded by Pleske^ in his »Revi- 

 sion der Turkestanischen Ornis» and the locality where it has 

 been coUected now seems to be more northern than its nor- 

 mal distribution.

The male specimen has very rich colours but is other 

 wise not remarkable. All the females have'a distinct bluish 

 shade on the rump and upper tail coverts. In the first 

 mentioned of the female specimens the tailfeathers are com- 

 pletely ashy grey only with a slight rufous shade on their 

 outer web. On the tailfeathers of the second female specimen 

 the rufous shade becomes more dominant on their distal 

 half although bluish ash is the ground colour. In both these 

 the tailfeathers are rather regularly barred by blackish. In 

 the third female the tailfeathers are light rufous, the trans- 

 verse bars are, narrower than in the others and mostly broken 

 up into irregular spöts, or entirely wanting in the distal 

 parts. The differences are consequently rather great and 

 more material is needed before any definite opinion can be 

 expressed about the variation of the Kestrel of the Tianshan
