PROSPECTUS. 
————<@———__— 
Tue ‘Birds of Africa’ will contain a résumé of what is considered of 
interest regarding the birds of the entire Ethiopian Region, which includes 
Tropical and Southern Africa with the surrounding islands. 
The five Subregions may be divided as follows :— 
West AFRrica: consisting of Tropical Africa’ west of 25° E. long., 
and southwards to the Quanza River, in about 10° S. lat. 
Sourm Arrica: south of 10° S. lat. and from 50° W. long. to 41° E. 
long.; this includes the African continent south of the Quanza 
and Rovuma Rivers, St. Helena on the west, but not the 
Comoro Islands on the east, and may include in the Southern 
Ocean the Crozet and Marion Islands, which are north of 
50° S. lat. 
East Arrica: Tropical Africa, east of 25° E. long. and between 
10° S. lat. and 1° N. lat., including the Victoria Nyanza, but 
not the Nile. 
Nortu-gast Arrica: Tropical Africa and the Red Sea, east of 
25° E. long., north of 1° N. lat., including the whole of the 
Nile water-shed north to Asuan. ; 
MapaeascaR: the island region between 41° and 65° E. long., from 
the Equator to 25° S. lat. 
The work will be divided into Volumes complete in themselves: thus, 
the present “ List,” and next the “ Classification” (which it is hoped will 
be issued this year). The “ Classification” will contain many ‘* Keys ” of 
the form adopted by the authorities of the British Museum in their 
Catalogues—the object of these “ Keys” being to clearly indicate in the 
fewest possible words the characters by which species may be readily 
identified and named. 
After the publication of the two above-mentioned volumes, the 
remainder of the work will be issued in probably yearly volumes, and will 
contain an ample résumé of all that is known regarding the birds in the 
Ethiopian Region, and will be illustrated in the best possible style with 
examples of all the hitherto unfigured, or incorrectly figured, species of 
that region.
