Genus Pogonorhynchus *, Van der Hoeven. 



1. P. ROLLETi. Pogonias rolleti, De Filippi, Rev. Zool. 1853, 

 p. 290. 



Not rare on the banks of the Bahr el Abiad, in 10° N.L. ; 

 found on high trees near the rivers, and in the wooded districts 

 of the Steppes to the south. This species, which I have 

 known since 1851, was accidentally omitted in my " Systematic 

 List of the Birds of N.E. Africaf." 



2. P. BIDENTATUS (Shaw). 



According to Dr. Riippell, common in Schoa. Rare on the 

 Upper Bahr el Abiad. 



3. P. LEUCOCEPHALUS. Pogouias leucocephaluSf De Filippi, 

 Rev. Zool. 1855, p. 291. 



Rather common on the banks of the Bahr el Abiad, south- 

 wards from the confluence of the Sobat and the Bahr el Ghazal. 



4. P. sALTii (Stanley). 



Not rare in Abyssinia, except in the coast-region and high 

 mountains, and also found in Sennaar and Kordofan, and along 

 the northern course of the Bahr el Abiad. 



5. P. viEiLLOTi (Leach). 



The most common species in Kordofan, Abyssinia, and Sen- 

 naar. The most northern limit of its range is between 14° and 

 15° north latitude. 



6. P. UNDATUS (Riipp.). 



Not very rare in Abyssinia and Sennaar. 



7. P. BiFRENATUs (Hcmpr. & Ehrenb.). Pogonias melam^- 

 cephalus, Riipp. 



Dr. Riippell, in his ^ System atische Uebersicht der Vogel 

 Nord-Ost-Afrikas,' declares this little species to be frequent in 

 Sennaar and Kordofan ; but this assertion is certainly not cor- 

 rect. The only country in N.E. Africa where I have found 

 this bird at all numerous is Eastern Abyssinia, especially in the 

 valleys of Morat and Moreb and the Habab territory. Nearly
