C. reichenovi from East Africa, from which, however, it is 
readily distinguishable by the sooty-brown colour of the 
breast and abdomen. This character also at once distin¬ 
guishes it from the other Double-collared Sun-birds of South 
Africa; it has, moreover, a very short bill, averaging 15 mm. 
What I take to be a young male, dated Aug. 3, is without 
the yellow tufts and has the abdomen greyish white. Two 
females in the series collected 1 can only distinguish from 
those of C. chalybeus by their short bills. 
[This pretty little Sun-bird was only found in the type 
locality, where it could not be considered common; it 
frequented certain flowering climbers bordering the paths 
and roads and a large species of flowering tree growing near 
my camp, in company with the other species of Sun-bird. 
In flight and call it resembles C. microrhynchus. 
The soft parts are:—Irides dark brown; bill, legs and 
toes black.]

[The Scarlet-chested Sun-bird was noted from the coast 
country of Natal and Zululand, the low veld of the North- 
Eastern Transvaal, and the Xnhambane, Beira, Gorongoza, 
and Tete districts of Portuguese East Africa. It seems to 
be more or less confined to the low t{ bush-veld ” country, 
and is commonly found wherever Kigelia exists, from the 
crimson blossoms of which it extracts nectar, poised on 
rapidly beating wings. In the Imhambane district it feeds 
on this and the “ caout-chouc 33 tree. Like most of the other 
Sun-birds, it varies its diet with insects. The flight is swift 
and darting, the call being loud and sharp, and the adult 
males sometimes indulging in a few warbling notes of 
a song. 
The soft parts are:—Irides dark brown; bill, legs and 
toes black.]
