Mr. D. A. Bannerman on rare Birds [Ibis, 
3. Lampribis olivacea. 
Ibis o/ivacea Da Bus, Bull. Acad. Roy. Sci. Belg. 1837, 
p. 105, pi. iv., et Esquisses Ornithologiques, 1845, p. 5, 
pi. iii.—Type locality : u La cote de Guinea/'’ 
The Coast of Guinea ! Clearly this is the 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 4 Bulletin ’ 
of the British Ornithologists’ Club, 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 rothschildi, 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 4 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), Cameroon, 
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 4 The Ibis’ [supra). It is quite a young bird, 
but is not nearly so spotted on the wing-coverts as other 
young birds of N, leuconotus in the British Museum.
