207. CossYPHA NATALENSIS. Natal Chat-Thrush. 
Bessonornis natalensis, Layard, B. 8. Afr. p. 181. 
A single specimen of this Chat-Thrush was obtained by Sir 
Andrew Smith near Port Natal, and the natives informed him that 
its habits were similar to those of C. bicolor of the Cape Colony. 
We have seen a few specimens from Natal, but it is not very 
common there. Captain Shelley met with it near Durban, amongst 
some scattered bushes in the more open country. It extends across 
the continent into South-western Africa, for it has been procured 
by Mr. Monteiro in Angola, and by Senor Anchieta at Biballa in 
Mossamedes. The latter observer states that it arrives from the 
interior like C. bocagii, and has the same name as that species, 
*€ Maxoxolo.” 
This species may be distinguished by the absence of an eyebrow, 
which makes it nearly allied to CO. bicolor, of which species Mr. 
Gurney has fancied it may be the immature bird. It is, however, 
quite distinct, being smaller than that species, and having the lores 
and cheeks bright orange instead of black. 
Adult.—Upper surface of body bluish grey, the mantle strongly 
washed with orange, the scapulars clearer grey; head and hind 
neck brownish orange, waved across with narrow greyish lines,
