 fact would suppose all the notes to be uttered by the same 

 bird." 



This habit is also mentioned by Le Vaillant, and a description 

 of a very similar habit in an allied species {Laniarius erythro- 

 gaster, Riipp.) is given by Ur. A. E. Brehm (J. f. O. 1856, 

 p. 481) as observed by him in Sennaar. 



The synonym of Laniarius ferrugineus, Cuvier^ applied by Mr. 

 Layard to this Shrike, is, as I learn from*Mr. G. R. Gray, in his 

 opinion, a doubtful one; and I have therefore adhered to the 

 name under which I have included the species in my sixth 

 additional List of the Birds of Natal (Ibis, loc. cit.)^.

 South-African Rook. 



This species is included in my fourth additional list of the 

 birds of Natal (Ibis, 1862, p. 152) under the above name, which 

 I believe has priority over the synonym of Corvus segetum, Temni. 

 (Rec. d'Ois. 7QS^'^ livr.), under which it appears in Mr. Layard's 

 ' Catalogue ^f.

This learned author also observes further that " Boulboul " is the com- 

 mon Lidian name for Pi/cnonotus bengalensis, and not to be confounded 

 with the " Boubou " of Le Vaillant.— Ed.]

 N. S. Philad. 1867, p. 216), that the name C. afer was conferred on this
