examine it. The natives assured me that the bird frequently 

 breeds on palms round Chartum. 



The other species of Asturina found in North-Eastern Africa 

 are: — 



1. ASTUR PALUMBARIUS, L. 



" Single, in Egypt/^ Riipp. Probably in winter only. 



2. AsTUR MELANOLEUCUs, Smith. Fazogloa, Paul von Wiir- 

 temb. 



3. MiCRONisus MONOGRAMMicus (Tcmm.). 



Rare, in dense bushes in Western Abyssinia (Galabat), in 

 Fazogloa, and along the Bahr el Abiad. This species is very shy, 

 appears to migrate, and to breed in the month of May. The 

 iris is very large and brown. 



4. MiCRONisus GABAR (Daud.). Var. nilotica, Sundev. 

 The most northern point of its occurrence on the Nile is, 



according to my observations, m Middle Nubia, in the provinces 

 of Dar-Mahas and Dar-Sukot. It is very frequent in Southern 

 Nubia, somewhat rarer in Kordofan, Abyssinia, Sennaar, on the 

 Bahr el Abiad and Bahr el Azrak. Lichtenstein, as long ago 

 as in his ' Doubletten-Verzeichniss,' pointed out the differences 

 between the eastern and western varieties : — " Specimina e Nubia 

 et Africa australi Nisum magnitudine superant : mas 14", foem. 

 15^" longa. Senegalensia autem multo minora : mas 10", foem. 

 ll'Monga; sed vix specie diversa." Conf. Sundev. Oefvers. 1850, 

 p. 132. 



5. MiCRONisus NIGER (Vieill.). 



Always met with singly in Western Abyssinia, Sennaar, and 

 Kordofan. The most northern point at which I have found this 

 species is Dabbeh, on the frontier between Dar-Dongola and 

 Dar-Schaikieh. I doubt not that it is a good species, different 

 from the preceding. Iris and feet pale yellow. 



6. AcciPiTER SPHENURUS (Riipp.). 



Rare in Kolla (Western Abyssinia) and on the Blue Nile ; pro- 

 bably in Southern Kordofan. The bird described* by Strickland 

 as a variety of this species probably belongs to A. minullus. A
