* It 13 impossible to adopt the name of vulfvrina for this species, as Daudin 

 founded this title on Levaillant's " Caffre," which, in the exercise of charity, we 

 may imagine to have been intended for the Black Eagle of South Africa ; but 

 inasmuch as he omits all mention of the characteristic white back, and describes 

 its habits most erroneously, we cannot allow his name to take precedence over 

 Lesson's description, which is most exact. The following synonymy applies to 

 Levaillant's species :— 



Le Caffre, Levaill. Ois. d'Afr. i. p. 28, pi. 6 (1799). 

 Falco vulturinus, Daud. Traife, ii. p. 53 (1800, ex Levaill.). 

 Gypaetus caffer, Hanz. Elem. Zool. iii. p. 45. 

 Haliaetus vulturinus, Vig. Zool. Journ. i. p. 336 (1824).
