also by the purplish to crimson beak.” It is this paler form 
which had originally been named afer, and therefore I had 
to give a name, viz. Turtur afer sclateri, to the dark West- 
African form. 
In connection with this correction Dr. E. Harrzrr called 
attention to another slip in the last Bulletin of the B. O.C. 
On p. 35 it had been said that a clutch of eggs of “ Musci- 
capa grisola”” was “entirely unpigmented.” Lvidently 
Mr. Bunyard thought that pigmented meant spotted, while, 
of course, it means coloured, and the eggs were by no 
means uncoloured, being light blue. 
Dr. Hartert, at the same time, raised a plea for some care _ 
in coining new specific, subspecific, or generic names. ‘This 
was nowadays more important than in olden times, since the 
Rules of Nomenclature most logically do not sanction the 
alteration, replacement, or correctyyn of such names. It 
was a pity to make ornithological nomenclature, for want 
of knowledge of alittle Latin or purposely, a laughing-stock 
of any advanced schoolboy. Every author who is not 
acquainted with classical languages can consult a friend or 
a dictionary, and nobody should recklessly create nonsense- 
names. One does not make so many new names, that a 
little time cannot be spent over a name which remains for 
all posterity. 
Lord Roruscuinp also exhibited an Eagle-Owl from 
North Algeria and made the following remarks :—No recent 
collector or observer has noticed Great Hagle-Owls in 
Northern Africa, except the Egyptian Hagle-Owl, Bubo 
ascalaphus. Only two authors, 7. e. Malherbe, 1846, and 
Loche, 1858 and afterwards, state that Bubo bubo is found 
in Algeria. We only know of one specimen now in 
existence of the latter, 7. e. Loche’s specimen from Teniet- 
el-Had, which is in Milan, and of which Mr. Whitaker says 
that it ‘is rather small and light-coloured.” The specimen 
which I have now received was shot in the forest of 
Bugeaud near Bone, in north-eastern Algeria, on December 
Ath, 1917, and sent to me by Monsieur Paul Dechabert. It
