This is undoubtedly an example of the western form of 

 Nightingale, and its occurrence so far south-east, especially 

 in May, is most remarkable. Dr. Radde (' Ornis Cau- 

 casica,' p. 246, footnote) has stated his belief that its 

 reported occurrence in the Caspian region was a mistake.

The eastern race of the Orphean Warbler is by no means 

 a well-marked form. In this specimen the bill is no longer 

 than that of the typical form ; but perhaps the best distinction 

 is in the colour of the flanks, which are never pinkish buff 

 as in the Western European bird.
