This species is not uncommon in the forests of the Knysna, and 
we have seen it from Swellendam. It occurs throughout the 
eastern province, for Mr. Rickard procured several at Hast London, 
but he met with it only once at Port Elizabeth. Lieut. Trevelyan 
tells us that he has seen very few specimens from the neigh- 
bourhood of Kingwilliamstown ; a few examples were contained in 
Mr. T. E. Atmore’s collection from Eland’s Post, and in Natal it 
also occurs sparingly. Captain Shelley only fell in with a few 
specimens in the latter colony, and Mr. Ayres, writing from Natal, 
says :— This bird, when sitting, resembles the Drongo Shrikes in 
appearance, but, on a near inspection, may be readily distinguished 
by its straight tail, that of the Drongos diverging broadly at the tip. 
The few I have seen were solitary birds. The one now sent I 
observed frequently fly down from the tree on which it was sta- 
tioned, on to the grass, to pick up caterpillars.” Mr. Andersson, 
who only procured this species in the neighbourhood of the 
Okavango River, states that it is migratory, and that he never saw 
it in Damara Land proper or Great Namaqna Land, and Senor 
Anchieta has only obtained it in Mossamedes, at Biballa and 
Cacondo, and at Humbe on the Cunene River. 
The Black Caterpillar Catcher is easily recognized by its entirely 
black coloration, which is glossed somewhat with green ; “ bill black, 
yellow at the gape, tarsi and feet black, iris very dark brown” (T. 
Ayres). Total length, 8°3 inches; culmen, 0°65; wing, 4:1; tail, 
41; tarsus, 0°75. The female is mottled with blackish bars on the 
back, and the under surface is white barred across with blackish 
brown.
