The eastern race of the Orphean Warbler is undoubtedly 

 the prevailing one in the Sudan. As this is the form 

 breeding in south-western Europe and western Asia it is 

 not surprising, but the bird from Shendi has the short bill 

 of the western race and is rather dusky bel )W, and we are 

 inclined to identify it with the western typical form.

The label gives : " Iris brilliant chrome-yellow, legs bright 

 straw-yellow. Two together in a tiny mimosa bush in tlie 

 desert." 



This little Warbler does not appear to have been pre- 

 viously met with in the Sudan, but it is known to winter 

 in Arabia and on the Somali coast, and it is not surprising 

 to find, it near Port Sudan.

Two of the Port Sudan birds have the forehead yellowish, 

 contrasting strongly with the dull brown crown and back ; 

 in the third example this colour has almost disappeared and 

 it resembles a bird from Shendi in the Museum identified
