We have followed Claude Grant in his revision of the 

 African Hoopoes, Ibis, 1915, pp. 276-281. U. e. senegalensis 

 is distinguished from U. e. epops, which is a winter migrant, 

 by its richer red back and generally by the absence of white 

 in the crest, though this latter character is not invariable. 

 We regard it as a resident African race of U. epops. There 

 is also a resident race, U. e. major Nicoll, in Egypt, but 

 we can find no occurrences outside Egypt. 



Madarasz, op. cit., described U. butleri from the Blue Nile 

 and distinguished it from U. e. epops by its smaller size and 

 from U. senegalensis by the presence of white in the crest. 

 This last character, as we have said, is by no means invariable 

 in U. e. senegalensis, and we have examples before us from 

 localities as far apart as Lake Chad and Somaliland which 

 show distinct traces of white. The size of Madarasz' bird 

 is certainly small, wing 125 ram.; the Butler birds before us 

 measuring (^ 132, ? 129, and the Christy bird 131 mm. 

 Typical West African U. senegalensis before us measure 

 132—135 mm., while Swainson's type was only 5 inches = 127 

 mm. We regret therefore that we can only regard U. butleri 

 as a synonym of U. e. senegalensis.
