ad. (St. Petersburg). Crown azure-blue surrounded by a white 

 stripe ; back and rump greyish blue ; rest of the head, neck, and the 

 upper parts, otherwise as in P. cceruleus except that the secondaries and 

 wing-coverts are more broadly tipped with white, and the outer web of 

 the outer tail-feather is white ; under parts white ; the breast and flanks 

 faintly tinged with primrose ; on the middle of the breast a dark blue line ; 

 beak horn-blue paler at the base ; legs plumbeous ; iris dark brown.

Hob. North Russia west of the Ural, and has occurred once 

 in Belgium. 



This species is intermediate between P. cyanus and P. 

 ccernleus, and is said to interbreed with both species. In its 

 habits it does not differ from them, and though its nest and 

 eggs are unknown they will probably be found to resemble 

 those of P. cceruleus.
