Mr. Axel W. Eriksson, well known as in former years the com- 
panion of the late Charles John Andersson, and as an explorer of 
Damara-land and the adjacent regions, has recently extended his 
travels to the Cunene river and to the Portuguese Province of Mossa- 
medes. I]]-health and the disturbed condition of parts of the country 
which he traversed much interfered with his collecting efforts ; but 
he succeeded in procuring a good many bird-skins, and, on a late 
flying visit to Cape Town, with his wonted liberality presented a set 
of them to the South-African Museum. 
In Damara-land he secured several examples of the rare Chetops 
pycnopygius (Sclat.) ; but most of his specimens were obtained from 
Biballa and Shella in Mossamedes. These included Caprimulgus 
fossii, Verr., Corythaix livingstonii, G. R. Gray, Chlorocichla 
occidentalis, Sharpe, Phyllostrephus fulviventris, Cab., and other 
species of interest ; and among them was a Cinnyris which appears 
to be new, and which I propose to name in honour of its discoverer, 
who has for so many years rendered good service to African orni- 
thology.
