301. DicrurUS MusicUS, Vieil. ; Musicapa Emar- 

 ginata, Licht. ; Le Drongear, Le Vail., PI. 167, 168. 



Entirely black, with forked tail, sometimes spotted with 

 whita on the breast and belly. Length, 10^" ; wing, 5" 9'" ; 

 tail, 4" 9'". 



This drongo shrike is very abundant in the Enysna forests, and 

 extends to Swelleudam, Beaufort, and the Karroo. I have also seen it 

 from Daniaraland and Natal. It is a bold, fearless bird, darting about 

 in the forest after insects, or chasing each other from tree to tree, 

 uttering loud cries, which to some ears are anything but musical. Le 

 Vaillant says they assemble in flocks, morning and evening, to catch 

 the bees as they go out from, or return to, their hives. He says they 

 make their nests in forks at the extremity of horizontal branches. They 

 are composed of roots and flexible twigs, and of such a loose texture, 

 that the eggs are plainly visible from below. The number of eggs is 

 generally four, sprinkled with black dots, nearly all of a square form.
