Recently published Ornithological Works. 769 
liis assistants during his hunting and scientific Expedition 
to Central Africa in 1897-8. The results are now being 
gradually worked out by different savants, and the birds 
have been naturally assigned to Dr. Reichenow, who has 
kindly furnished us with a copy of his report on this subject. 
To make his memoir more complete, Dr. Reichenow has 
included in it notices of other recent work in the same 
district of Africa, which he calls the Mid-African Lake- 
district,” and of which he gives us a useful outline-map. 
The Mid-African Lake-district, he tells us, is specially 
rich in bird-life. At present we know of 750 species from 
this country—that is, about one-fourth of all the known 
species of the Ethiopian Region, which is estimated to 
contain about 3000 species. This richness in species comes 
from the central position of the Province. West Africa 
supplies the greater portion of them, as out of 750 species 
about 130 may be classed as West-African forms. Typical 
East-African forms are about 100 in number, and 70 extend 
over East and South Africa, while about 100 of them are 
generally spread over the whole Ethiopian Region. The 
European-Asiatic migrants that are known to occur in the 
Lake-district are about 50 in number. 
The author proceeds to record the species of the Lake- 
district according to the nomenclature and arrangement of 
his ‘ Vogel-Afrikas/ and adds many good notes. Coloured 
figures are given of Scoptelus adolphi-frederici, Malaconotus 
adolphi-frederici , Cinnyris schubotzi , Pyromelana leuconota , 
and Bradypterus milbreadi.

This is an interesting essay to those who are studying 
geographical distribution. The author, who is one of the 
officials of the Museum Goeldi at Para, and is very well 
acquainted with the birds of Lower Amazonia, shews, or 
attempts to shew, that the birds of the campos of that 
district (that is, of the treeless spaces, surrounded by forest,
