The Yellow-mouthed Tit inhabits South-eastern Africa. 



The type was procured by Bradshaw during his travels 

 between the Limpopo and Zambesi rivers, and when it passed 

 into my collection I noted it as coming from the Zambesi on 

 account of the number on the label attached to that specimen. 

 In the British Museum there is a specimen from Grahams- 

 town in Cape Colony, one of Atmore's collecting. The species 

 has since been found by Mr. Alexander Whyte at Mpimbe in 

 the Upper Shire.
