XVI. — On the Ibis olivacea of Dubus. 

 By T. Salvadori, F.M.Z.S. 



The Ibis olivacea of Dubus is perhaps the least known of the 

 members of the family Ibididae, and one about which many 

 mistakes have been made, even quite lately. Having recently 

 received an adult specimen, procured by Signor Leonardo 

 Pea in Prince's Island, I hope to be able to settle the 

 status of the species. 



Ibis olivacea was first described by Dubus (Bull. Ac. Brux. 

 1837, p. 105), who gave at the same time a very good 

 figure, which, strange to say, has remained unnoticed by 

 every ornithologist treating of this species. The type- 

 specimen was contained in a box of skins, said to be from 

 Guinea, bought by the King of the Belgians, and presented 

 to the Museum of Natural History of Brussels. The box 

 contained also the type-specimen of Ardea calceolata, de- 

 scribed and figured by Dubus in the same Bulletin*. 



Later, in 1845, Dubus again figured Ibis olivacea in his 

 ' Esquisses Ornithologiques, ' i. pi. 3. Apparently from this 

 figure Reichenbaoh took that which he published in the 



* " Description d'une Espeee nouvelle de Hfron," par le Chevalier 

 l'». Dubus (op. cit. pp. 39-41, pi.).
