SAVI'S WARBLER. 159 



BLACK REDSTART. 



RUTICILLA TITHYS. 



Sub-family TURDIN^E. Genus RUTICILLA. 

 Tithys' Redstart Black Redtail. 



A regular but very scarce winter visitor to the 

 southern counties of England. It may be distinguished 

 from the Common Redstart by the intense black colour 

 of the under parts, where the latter bird is reddish 

 brown. The eggs, five or six, pure glossy white, are 

 very fragile and delicate ; but the evidence of it breeding 

 in England is not very conclusive. 



RED-BREASTED FLYCATCHER. 



MUSCICAPA PARVA. 

 Sub-family TURDIN^E. Genus MUSCICAPA. 



Has occurred a few times in Britain ; the last occa- 

 sion being at Scarborough in October, 1889. 



SAVI'S WARBLER. 



LOCUSTELLA LUSCINIOIDES. 



Sub-family SYLVIIN;E. Genus LOCUSTELLA. 



A bird which used to inhabit the % fen-country in 

 Norfolk, Huntingdon and Cambridge. Since the fens 

 have been drained, the bird has in all probability be- 

 come extinct.
