432 Mr. W. L. Sclater on Birds collected 
a male, and, like the other three, has the outer tail-feather 
elongated. 
Dr. Sharpe has described (Bull. B. O. C. xvi. 1906) 
a Blue Swallow from the Mabira Forest, Chagwe, Uganda, 
as H. christyi. I cannot see any difference between 
this supposed species and H. atroccerulea, and should be 
certainly inclined to consider them identical. There are two 
examples of H. christyi , both males and both taken in the 
Mabira Forest, on Aug. 7 and Sept. 11 respectively. I should 
infer, therefore, that this bird winters in Uganda and comes 
south in October to breed in the Eastern Transvaal and Natal. 
The only two dated examples in the British Museum are 
Wahlberg's, taken at Umvoti, Natal, Jan. 9, 1843, and 
Seebolmds, taken at Lidgetton, Natal, March 29; these both 
confirm my supposition. 
[“ Nkonjane ” of Zulus. The is the Zulu name for all 
Swallows. 
This beautiful little Swallow was noted only from 
Western Zululand and the North-Eastern Transvaal. 1 have 
no data to shew whether or not it is resident in Zululand, as 
it is stated to be in Natal, but certainly in the North-Eastern 
Transvaal it is migratory, as it did not appear till the summer 
season had set in. Its flight is graceful and usually close to 
the ground, the birds choosing some sheltered spot under 
the lee of a wood or a road-cutting. The flight is seldom 
long sustained, and they will perch both on posts and wire¬ 
fencing or outstanding twigs of the trees. 
The male, which is easily distinguished on the wing by its 
brighter colouring and the long filaments to the outer tail- 
feathers, has a sweet warble or “ song,” which is uttered only 
on the wing. 
I was told by the natives in Zululand that this species 
breeds in holes in the ground, after the manner of H. griseo- 
pyga , and I saw females in the North-Eastern Transvaal enter 
and leave holes in the hill-sides, but I did not succeed in 
finding any actual nests. 
The soft parts are :—Xrides dark brown; bill, legs and 
toes black.]
