580 Mr. W. R. Ogilvie-Grant on Birds from 
about 2:8. On examining the specimens of Heterocorax in 
the British Museum, we find that examples procured at 
Swellendam and Deelfontein in Cape Colony, as well as those 
from Zululand and Namaqualand, belong to the larger-billed 
form, and that specimens from Mashonaland, Damaraland, 
Angola, Lado, the White Nile, and Abyssinia belong to 
the smaller-billed H. minor, while those from the Transvaal 
appear to have the bill intermediate in size. We mention 
this point, as Dr. Reichenow, who recognises the two forms, 
limits the range of H. minor to North-east and East Africa, 
but our specimens shew that it really extends much further 
south. The fact is that though typical males of H. capensis 
from Cape Colony and of H. minor from Abyssinia seem very 
distinct when compared, a series of birds from intermediate 
districts of Africa shews that the two forms completely 
intergrade.
