considerably paler than the birds in full plumage. These 

 feathers are also margined with gray. The back and the 

 crown are gray mingled with rusty red and the upper tail- 

 coverts are of the same colour. The secondaries have white 

 points and margins and the abdomen is palé gray without 

 any rusty red. The mantle is gray with a touch of black. 

 This bird is breeding in all the Tian Shan districts and 

 seems to have been common enough at Narin.

I have refered these birds to Luscinia suecica pallidogu- 

 laris Sar. because they are paler than the typical Luscinia 

 suecica L. They also have the 2nd primary in length be- 

 tween the 7tl^ and 8th which is a trait of characteristic to 

 Luscinia suecica pallidogularis. The auriculars are of the 

 same colour as the feathers on the crown and the neck 

 while birds both from Sweden and northern Russia have the 

 auriculars paler brown. The dorsal parts of the body are 

 also paler than in swedish specimens which is also the case 

 concerning the blue patch of the breast. The hazel coloured 

 feathers below this blue patch are more indistinct than in birds 

 from Kola and Sweden, and the under parts as well as the 

 abdomen of a more grayish colour. The swedish and russian 

 birds seem to have the tarsi longer than the Tian Shan ones. 

 I have measured some and they are between 25—27 mm. 

 while in the Tian Shan birds they are 24 mm. The bilis of 

 the birds from the western Palearctic region also seem to 

 be shorter.
