very (lark stage of plumage, and is not unlikely to 

 wander to Africa, A. r. albicans or rather raptor and 

 A. r. vindhiana appear to be indistinguishable, except 

 in the fully adult when they are very distinct. 



Also on p. 697 under Aquila rapax albicans [0. & L. 

 coll.], for 1 Erkowit read 4. 



Ibis, 1919, p. 699. Bttteo hicteo rufiventer. According to 

 Richmond, Auk, 1919, p. 549, the earliest name for 

 this species is Falco rufocanus, Forster's edition of 

 Levaillant's Oiseaux d'Afrique, 1798, pi. 17. The 

 finding of this little -known work involves also 

 changes in the names of the Jackal-Buzzard and 

 Kolbe's Vulture. In the case of the Desert Buzzard, 

 however, Forster's name is founded, like Daudin's Falco 

 desertorum, on Levaillant's plate, and if this is not 

 identifiable as stated by Hartert, the name Falco 

 rufocanus is in the same category as Falco desertorum, 

 and neither can be used.
