110 Mr. D. A. Banneriiian on rare Birds [Ibis, 



3. Lampribis olivacea. 



Ibis olivacea Dii Bus, Hull. Acad. Roy. Sci. Bclg. 1837, 

 p. 105, pi. iv., et Esquisses Oniitliologiqiies, 1845, p. 5, 

 pi. iii. — Type locality : " La cote de Gtiinea.^^ 



The Coast of Guinea ! Clearly this is tlie type locality of 

 Lampribis olivacea and not Prince's Island, so that if it is 

 proved that the Prince's Island bird and the bird from the 

 mainland are different, the name Lampribis olivacea (Du Bus) 

 must apply to the mainland bird, and the Prince's Island 

 bird requires a new name. This I named in the ' Bulletin ' 

 of the British Ornithologists' Chib, vol. xl. 1919, pp. 4-7, 

 to which I must refer the reader ; and in this paper, as the 

 Prince's Island bird was left without a name, I named it 

 Lampribis rothsc/iildi, and made the type an adult male in 

 the Genoa Museum, collected on the 26th of January, 1901, 

 by Leonardo Fea at Infante d'Henrique, Principe. I have 

 given a full description of this bird in the ' Bulletin ' 

 (/. c. p. 7), and will not therefore repeat it here. 



Briefly, then, we have the following forms in this genus in 

 West Africa : — 



Lampribis rara. Gold Coast (terra typica), C!ameroon, 



Gaboon, and Upper Congo. 

 Lampribis olivacea. The Coast of Guinea (terra typica), 



S. Cameroon. 

 Lampribis rothschildi. Prince's Island (terra typica), 



St. Thomas Island. 

 Lampribis SPLENDIDUS. Liberia (terra typica). 



Nycticorax leuconotus. 



Ardea leuconotus Wagl. Syst. Av. 1827, p. 189 (sp. 33) — 

 Type locality : Senegambia. 



Nycticorax leuconotus Bates, Ibis, 1911, p. 485. 



The immature male Heron (No. 4042) which Mr. Bates 

 obtained at Bitye on the 29th of November, 1909, can be 

 none other than N. leuconotus^ to which species he correctly 

 assigned it in ' The Ibis' {supra). It is quite a young bird, 

 but is not nearly so spotted on the wing-coverts as other 

 young birds of A^. leuconotus in the British Museum.
