Von Heuglin's attempt to substitute his name C. 

 RilppelU, published without any description in his " Syst- 

 Uebers." in the Sitzungsberichte der mathem.-naturw. 

 Classe der Kais. ATcad. der Wissenschaften (Vienna) 

 for 1856, and only described in Cabanis' "Journal 

 fiir Ornithologie " for 1861, for Von MliUer's name 

 C (equator icdis, published with a description in the 

 Naumannia for 1851, and figured in Von Miiller's "De- 

 scription des nouveaux Oiseaux d'Afi-ique," published 

 in 1853, deserves especial notice and reprobation. The 

 excuse given in Von Heuglin's nate, " Ornith. N. 0. 

 Afr." p. 142, that the name C. cequatorialis cannot be 

 retained because the species has not yet been observed 

 south of 14° north lat., is scarcely valid.

 Anseba valley many appeared at the end of July, none 

 being seen before the 25th. Some of the specimens shot 

 had pale edgings to the feathers, and were evidently 

 young birds ; others were of uniform colour.
