[Chr. coll.] 1 Meridi Jan. B.G. ; 4 Yei Nov. Dec. L.E. 



One of Yei birds has light edges to the secondaries and 

 might perhaps be a P.p. mesoleucus, but it is impossible to 

 distinguish them when out of plumage. 



A common winter visitor to the Sudan. 



Phcenicurus ochruros.

These are all females, and it is impossible to determine 

 to which race of the Black Redstart they should be assigned. 

 There are several other examples in the British Museum 

 also indeterminable. In Abyssinia and Somaliland the 

 prevailing form would appear to be P. o. phoenicuroides, if 

 this is really separable from P. o. ochruros. 



Ileuglin states that the Black Redstart comes to southern 

 Nubia only in the winter.

Only one of these birds is in full plumage ; it appears to 

 belong to the typical race which breeds in north-east Europe 

 and western Siberia. 



Scarce as compared to its abundance in Egypt {A. L. B.).
