authors have thought to be the typical afra. The latter 
name was given by Linnzus (Syst. Nat. ed. xii. 1. p. 284, 
1766) to Brisson’s “ Turtur senegalensis,” i. e. the Blue- 
spotted species from the Senegal. From Senegambia no 
skins were available ; but we have now received three skins 
from Senegambia, collected by F. W. Riggenbach, which 
are strikingly different from the birds from Western Africa 
generally, not only by the much darker and browner colour 
of the upperside and the richer, more rufescent breast, but 
also by the purplish to crimson beak. The dark West- 
African form, which ranges from Sierra Leone to the Niger 
and Angola, and eastwards to Uganda (Iintebbe) and the 
Tanganyika district and Nyassaland, also the Zambesi, 
I name

Sharpe’s “ abyssinica ” and “ delicatula”’ were practically 
only separated by the colour of the bills in dry skins, and 
I have hardly any doubt are one and the same form. 
The pale form with blackish bill would therefore range 
from the Senegal to the Togo hinterland (Gambaga, Mangu) 
and eastwards to the Blue and White Nile, Nubia, where my 
brother got it as far north as Neikhala on the Atbara, and 
Abyssinia (Erithrea). The name of this form is un- 
doubtedly 
Turtur afer afer (L.), 
and “abyssinica” Sharpe is doubtless, and delicatula probably 
also, a synonym. 
Turtur afer sclateri is named after Mr. W. L. Sclater, who 
reviewed these little Pigeons in ‘ The Ibis,’ 1912, p. 35. 
It has been pointed out by Mr. Mathews, and accepted 
by C. Grant and others, that the genus Chalcopelia auct. 
must be called Turtur, while the generic name of the Turtle- 
Doves is now generally accepted to be Streptopelia. 
Dr. Harterr exhibited a new subspecies of a Sun-bird, 
which he described as follows :—
