WARBLERS 3 5 i 



1. Motacilla suecica of Linna3iis. The eastern and 

 northern form, with a red spot in the centre of the 

 blue throat. 



2. Sylvia leiicocyanea of Brehm. The western and 

 southern form, with a ivhite spot in the centre of the 

 blue throat. This may be regarded as the ordinary 

 Dutch and German form. 



3. Sylvia woljii of Meyer, with the entire throat blue. 

 This is the rarest of the three in collections. It is 

 said to be more common in Russia, and has been 

 met with in Holland and in Spain. 



See remarks on hybrids between the different 

 forms : Suchetet, " Oiseaux Hybrides," p. 349. 



So far as can be ascertained, the form met with 

 in Great Britain has been No. 1, the true suecica, 

 although in two or three cases a white-spotted 

 bird is stated to have been obtained. The follow-
