November 26, 1850.— R. H. Solly, Esq., F.R.S., in the Chair. 



List of Birds procured in Kordofan by Mr. J. Petherick. 

 With notes by H. E. Strickland, M.A., F.G.S. 



[Species not enumerated in Riippell's 'SystematischeUebersicht der 

 Vogel Nord-Ost-Afrika's,' 8vo, Frankfurt a. M. 1845, are marked N. 



Species common to the West Coast of Africa are marked W. These 

 are chiefly determined by reference to Dr. Hartlaub's valuable list of 

 West African birds in the * Verzeichniss der offentlichen u. Privat- 

 Vorlesungen am flamburgischen Gymnasium,* 4to, Hamburg, 1850.] 



1 . Neophron percnopterus. 



2. Vultur occipitalis. 



3. Otogyps auricularis. 



4. BuTEO rufipennis, Strickland, n. s. Upper parts cinereo- 

 fuscous, nearly black on the crown ; feathers of back and wing-covers 

 with black shafts ; cheeks cinereous, a black line below them from 

 angle of mouth ; chin whitish, with a medial dark streak ; breast and 

 sides ferruginous brown, with a conspicuous medial black streak one- 

 sixteenth of an inch wide on each feather ; belly, thighs and vent 

 plain fulvous ; primaries and secondaries bright ferruginous, tipped 

 for about an inch and a half with black, and from three to five distant 

 transverse black bands on the inner web ; tail cinereo-fuscous, with 

 five dark fuscous bands, each about a quarter of an inch wide, the 

 distal one about half an inch, beyond which the extremity is cinereo- 

 fuscous and the extreme tip white ; cere and legs yellowish ; beak 

 and claws black. 



Length 17 inches; wing, 12| ; medial rectrices, 7i; external 

 ditto, 7\ ; tarsus, 2\. 

 Hah. Kordofan. 



5. Aquila ncevia. 



6. Aquila pennata. 



7. W. Cir cactus brachydactylus. 



8. Helotarsus ecaudatus, 



9. Falco biarmicusy Temm. {F. peregrinoides, Temm. ; F. chi- 

 queroides, Smith ; F. feldeggiy Schlegel ; F. lanarius, Schlegel ; F. 

 rubeus, Thienemann ; F. cervicalis, Kaup.) 



After a careful examination of many specimens, I feel justified in 

 uniting the above synonyms under one species. This is essentially 

 an African bird, extending from the Cape of Good Hope to Egypt, 

 whence it has probably spread into Greece and Dalmatia, to which 

 portions of Europe it is chiefly confined, though a single straggler 

 has occurred in Germany. It is at once distinguished from F. pere- 

 grinus by the shorter toes, and the fulvous patch on the crown. The 

 Falco juggevy Gray {F. luggur, Jerdon), of India is closely aUied, but 

 seems to diff'er constantly in the plumes of the tibia being uniformly 

 dark brown, while in F. biarmicus they are cream-coloured or white.
