as new by Dr. Reichenow, and are named Theristicus brevi- 
rostris , Aplopelia (scr. IJaplopelia) tessmanni , Psalidoprocne 
tessmannij Pedilorhynchus tessmanni, and Bradornis sylvia.

In the years 1908-9, the Imperial Colonial Office of 
Germany sent out a Zoological and Botanical Expedition to 
the Protectorate of Cameroon on the western coast of Africa. 
The collectors were Herr Riggenbach and Herr Hauptmann 
Striimpell, who brought back about 1000 bird-skins. These 
are referred by Dr. Reichenow to 305 species, of which 
34, new to science, have been - already characterized by 
Dr. Reichenow in the f Ornithologische Monatsberichted 
A list is now given of the species and the exact localities 
in which they were obtained, with a few notes. The localities 
are further indicated by an outline map, which gives the 
routes followed by the expedition. 
Appended is a list of all the species of birds that are as 
yet known to occur in the Protectorate of Cameroon, with 
their localities, altogether 670 in number.
