528 Mr. P. L. Sclater 07i the Geographical 



Passingr on to the north of the Zambezi to the division 

 proposed to be called " Soutb-eastern Africa/' we shall find 

 that great progress has been made as regards our knowledge 

 of its birds during the past fifteen years, Peters's long- 

 promised volume on the birds of Mozambique was, it is true, 

 never published, but sever.d more receut German explorers 

 in South-eastern Africa (Bohm, Hildebrandt, Fischer, Stuhl- 

 mann, Emin Pasha) have stored the rich bird-collection of 

 their Fatherland with series of specimens from the interior 

 of this district, and many valuable papers have been based 

 npon them (41-47). 



Several English collectors (Lort Phillips, Johnston, Hunter) 

 have also been busily engaged in the same country and on the 

 adjoining coast of Somaliland (48-50), and, judging by the 

 fine series which has only recently reached England from 

 Mr. Jackson (51), the riches of this avifauna are by no 

 means yet exhausted. 



In North-eastern Africa, commonly so-called — that is, 

 Abyssinia, Nubia, and Egypt — comparatively little has been 

 done since the issue of the works mentioned in my British 

 Association ''Address." We must not, however, forget to 

 mention Count Salvadori's excellent memoirs on the birds of 

 Shoa (52, 53), based upon the collections made by the Italian 

 expeditions to this part of Abyssinia. 



Little also has been done as regards the avifauna of Arabia, 

 where there seems to be still room for ornithological dis- 

 coveries to be made. But the adjacent island of Socotra, 

 which belongs to this subdivision, was zoologically explored 

 by Prof. I. B. Balfour in 1880, and as regards its birds the 

 results are given in Dr. Hartlaub's paper published in the 

 Zoological Society^s 'Proceedings' for 1881 (54). 



7. Lemurian Subregion. 

 As I have already said above, it is somewhat doubtful 

 whether, except for convenience' sake, the Lemurian Sub- 

 region can be properly annexed to the Ethiopian Region. 

 There can be no doubt of the highly specialized character of 

 its birds, and some modern authorities consider that, as
