BIEDS OP EGYPT. 325 



has probably been met with in Egypt, though it is open to 

 doubt. Buteo deserforum is also probably Egyptian, but 

 I can find no positive evidence of its having occurred there. 

 Haliaetus albicilla opens up a subject for investigation 

 whether it be the true H. albicilla, a small subspecies, as Von 

 Heuglin asserts, or a new species. I include Aquila fulva, 

 A. navioides, and A. Bonellii upon Von Heuglin's authority. 

 The immature A. imperialis has been occasionally mistaken 

 for A. ncBvioides ; and I do not feel certain that Von Heuglin 

 may not have fallen into this same error. 



Gi/paetus nudipes, I think, may be safely considered to be 

 the only representative of that genus in Egypt. 



Fam. CoLUMBiDiE. — Columha livia and C. ScJiimperi, I 

 believe, are both plentiful in Egypt and Nubia, while I think 

 there are good reasons to doubt C. oenas being found there. 



Turtur Sharpii is not only distinct from T. auritus in 

 plumage and measurements, but decidedly so in its habits. 

 T. albiventris is included on the authority of Von Heuglin, 

 and I have no doubt he is correct. T. isabellinus rests on the 

 authority of Bonaparte (Ic. Pig. t. 102). As I only know it 

 from the figure, I am unable to decide its claims to a place 

 in the Egyptian avifauna ; but it appears to me very possible 

 that the locality may have been wrongly given to the speci- 

 men which formed the subject of that plate. The type is in 

 the Berlin Museum. 



Eam. TetkaonidjE. — The Francolin appears very doubtfully 

 Egyptian, being only included upon Riippell's list, which is, 

 perhaps, the most untrustworthy authority we have upon 

 Egyptian birds.
