222 CORACINA PURA 
Adult female. Distinguished from the male in having no black on the 
head, the feathers in front of the eye being grey. Wing 5:0. Pinetown 
2 26.8. 75 (T. L. Ayres). 
Immature. Similar to the female, but with scme narrow white edges 
to the quills and outer greater coverts ; under tail-coverts, with a black sub- 
marginal bar on each feather. Wing 5:0. Durban ? 31.3. 74 (Shelley). 
The Grey Cuckoo-Shrike was first discovered by Levaillant, 
who found it common in the forests of the “ Outeniqua,” on 
the banks of the Sunday and Swartkops Rivers of Cape 
Colony. Westward of this it extends as far as Grootvaders 
Bosch in the Swellendam division, where it was met with by 
Taylor, eastwards through Pondoland and Natal to Zululand, 
and, according to Taylor again, as far as the Letaba Valley, 
in the Zoutspansberg district of the Transvaal. North of 
this point I have not heard of its occurrence either in Rhodesia 
or British Central Africa. 
There are examples in the British Museum from George 
(Atmore), Knysna (Andersson), and King William’s Town 
(Trevelyan) in Cape Colony; from Durban (Ayres), and New- 
castle (Reid) in Natal; and from Zululand. 
This bird is confined to forest districts, and keeps much 
to thick bushes and to the tops of tall trees, so that it escapes 
observation and is not frequently met with. It feeds chiefly 
on caterpillars. Levaillant states that he examined 160 
stomachs and that they contained nothing else, but Short- 
ridge found beetles in one specimen. Its voice is not 
loud, its cry being a harsh scream. It is sometimes seen 
alone, though more often in small parties of five or six 
individuals. 
The nest and eggs do not appear to be known.
