4. A riclier-eolonrcd darkci -backed race, more like the 

 Egyptian race 011 the back but with a much more 

 rufous tone, especially on the breast, and smaller. 

 This race comes from the Kilimanjaro region and 

 Masailand, and its name is P. s. olivascens Hai'tert 

 (O. M. xvii. 1909, p. 183: Canipi ya Simba, B.E.A.). 



Outside Africa two other races have been described, P. s. 

 orientutis Hartert from India and P. s. erlangeri Neum. 

 from southern Arabia. 



We cannot admit that Lichtenstein's P. senegalensis is

 On examining the series from the whole range of this 

 s[)ecies, it was evident at a glance that there were two or 

 three races. The Indian birds stand out as dark and well- 

 marked, and southern Tunisian examples appear exactly the 

 opposite. Inasmuch, however, as our birds are the typical 

 race we will leave the naming of these to others.

These birds are in all probability the typical form, though 

 the term " Nubia ^' as used by Temminck is rather vague. 

 The following races of this species luive been separated, but
