SCLATER ON THE GENERAL DISTRIBTJTION OE AVES. 139 



rous. Several groups of birds^ which eeem clearly entitled to rank 

 as distinct families, or at least as subfamilies, are wholly peculiar 

 to this region, such as the Coliidce, Musophagidce, and Buphagincd. 

 There are also very many genera, of which the species aj'e all con- 

 fined to this continent ; the principal of which I have enumerated 

 in my List of Typical forms. The island of Madagascar, however, 

 is the locality where the African type seems pushed to its utmost 

 degree of development. There are many genera quite peculiar to 

 this island, or which have a single representative or so upon the 

 adjacent coast of the continent. Such are Oriolia, Atelornis, Bra- 

 cJiypteracias, Vang a, and others which I have mentioned above, not 

 to mention the extinct gigantic uEpyornis. Bourbon, Mauritius 

 and the other Mascarene islands all belong to Africa zoologically, 

 and have only recently lost the now extinct birds of the genera 

 Didus, Fezophwps and their allies, which were, so far as we know, 

 types quite peculiar to this locality. 



Dr. Gr. Hartlaub's lately published System der Ornithologie 

 West' Africa' s gives as inhabitants of that part of the continent, — 



Accipitres 56 -\

Scansores 69 



Columbae 17 



GaUin^ 19 



Struthiones 1

In the preface to Dr. Hartlaub's work will be found a resume 

 of all the most important facts known concerning African Orni- 

 thology. 



For North-eastern Africa we have a List lately published by 

 Dr. Heuglin, who mentions — 



1. Accipitres 95-\ 



2. Passeres 372 



3. Scansores 38 



4. Columbae 14 



6. Galling 24 



6. Struthiones .... 1 



7. Grallaj 130 



8. Anseres , 80^ 



A correct catalogue of the Birds of S. Africa would probably be 

 not less numerous in species.
