yellow ; under tail-covcrts white ; feathers of thighs dusky, 

 tipped with white. The tail is considerably shorter than in 

 E. j^oHoxantha.

 black ; iris orange. Total length (measured in flesh) 3*56 

 inches, culmen 0"5, wing 2'\, 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 retorncd to camp highly delighted, 

 having shot this little Eremomcia, wliich 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 (Riipp.). 



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 Avay 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.
