 the fauna of Abyssinia has, almost without exception, 

 been performed by German and French travellers and 

 naturalists. Foremost amongst these stands Rtippell, 

 who made two long journeys in North-eastern Africa. 

 The natural history results of his travels were published, 

 principally in three works, to which frequent reference 

 will be made in the following pages. These works

 Africa's" (Systematic Eeview of the Birds of North- 

 eastern Africa). 1845. This is a complete hst of all 

 the birds at that time known to have been found in the 

 Nde valley, Abyssinia, and the countries on the shores of 

 the Eed Sea. The number enumerated is 532. 



A large number of alterations and additions have 

 since been made to this list, but it contains a very 

 large amount of valuable information. Several new 

 species were described in each of the three works, those 

 in the " Systematische Uebersicht " being all birds, 

 admirably figured by Wolf; whilst in the two earlier 

 works numerous kinds of mammals, reptiles, and fishes
