1920.] the Birds of the Avglo-Egyptian Sudan. 833 



west African form from l)irds from the rest of Africa. We 

 must also separate the northern Sudan birds as above. The 

 African races then appear to be : — 



1. S. S. SENEGALENSIS. 



Coliimha senegalensis Linn. Syst. Nat. 12th ed. i. 1766, 



p. 283 : Senegal ex Brisson. 

 Rufous both on back and underside with very little 



bluish tinge, the breast below the cobar being 



strongly reddish pink. Wing 130-137 mm. 

 Range. Senegal probably to Northern Nigeria. The 



only example from the latter district we have appears 



to be nearest to the typical race. 



2. S. s. jEQUatorialis, op. cit. 



A less reddish bird above and below ; this is most 

 noticeable just below the collar where the breast is 

 merely vinous pink, not reddish pink. Wing 132- 

 144 mm. 



Range. Fi-om St. Thomas Island through Southern 

 Nigeria to the Bahr el Ghazal, Abyssinia, north to 

 the Red Sea Province of the Sudan, Somaliland, 

 and all Africa south of these countries. Also to 

 S. Arabia and possibly Palestine. 



3. S. S. ^GYPTIACA. 



Columba iegyptiaca Lath. Ind. Orn. ii. 1790, p. 607 : 



ex Forskal, Egypt. 

 A very rufous bird, redder even than 8. s. senegalensis 



and larger, wing 133-151 mm. ; the rufous of the 



breast extends far down the chest, and that of 



the back on to the rump. 

 Range. Egypt only. 



Plate V. of the J. f. O. 1905 gives a very fair idea of 

 the distinctions of these three races. 



4. S. S. SUDANENSIS, Op. cit. 



Differences as above. 



Range. Wadi Flalfa to Lake No.
