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. Pogonias leucocephaluSy 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 (Rupp.). 
Not very rare in Abyssinia and Sennaar. 
7. P. bifrenatus (Ileiupr. & Ehrenb.). Pogonias melarn- 
cephalus , Rupp. 
Dr. Riippell, in his £ Systematische 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
