not so common: I have observed it, though very sparingly, in 
Damara and Great Namaqua Land, and near the west coast of the 
Cape Colony. I have also obtained specimens from the Okavango, 
which are of a darker and richer hue than those from Damara and 
Great Namaqua Land : this is also the case with specimens from the 
western parts of the colony.”

Professor Sundevall gives the following diagnosis for this 
species :—“ Dull yellowish olive: underneath dull yellow: sides of 
neck, thighs, rump and vent tinged with buffish colour: head rather 
dusky above, with a dull yellowish superciliary streak; third quill

infra). Sir A. Smith procured the species near Port Natal, but his 
typical specimen did not come into the British Museum. Mr. T. 
Ayres has also met with it in Natal, and Captain Shelley has
