74 Mr. B. Alexander —An Ornithological 
yellow; under tail-coverts white; feathers of thighs dusky, 
tipped with white. The tail is considerably shorter than in 
E. polioxantha. 
Adult 2 . Upper mandible brown, lower horn-colour; tarsus 
black; iris orange. Total length (measured in flesh) 3*56 
inches, culmen 05, wing 2T, tail 1*18, tarsus 0*6. 
Hab. Mesanangue, Zambesi river. 
It was quite by accident I obtained this bird. My native 
“ boy/ ; who was anxious to learn how to shoot, begged hard 
one afternoon to be allowed to take out one of my small 
guns. He afterwards returned to camp highly delighted, 
having shot this little Eremomela , which he had observed in 
some thick bushes on rocky ground close to the river. 
79. Eremomela usticollis (Sundev.). 
By no means plentiful, and only observed on the higher 
reaches of the river from Zumbo onward, frequenting the 
tops of tall acacia-trees in pairs, and generally in company 
with other small insect-feeding birds. 
The male has a pleasing little song. 
Adult. Total length (measured in flesh) 4*34 inches. Iris 
lemon-yellow; upper mandible brown, lower horn-colour; 
legs and feet yellowish flesh-colour. 
The range of this species extends from the Transvaal to 
Zumbo, on the Zambesi, on the east, and Damaraland on the 
west. 
80. Camaroptera brevicaudata (Rupp.). 
By no means plentiful, frequenting bush-grown localities 
and the outskirts of woods. Our three specimens were 
procured at Zumbo. In the pairing-season this bird produces 
a whirring sound with its wings when travelling from branch 
to branch. It is chiefly resorted to by the male as a means 
of attracting the female to its side when the pair are threading 
their way through thick undergrowth, and appears to take 
the place of a call-note. 
This bird is unusually silent, and never once did we hear 
it give vent to any note. 
Adult. Bill black ; iris orange; legs and feet flesh-colour.
