476 Mr. D. A. Bannerman on the 



3. 7000 to 7500 ft. : tree-fern belt. 



4. Above 7500 ft. the forest begins to give way to grass- 

 country. 



5. 8000 ft. and upwards. 



{a) The first ridge of the Peak is reached, grass-grown 

 and scarred by deep channels and cavernous 

 fissures. 



(6) Above the grass-country the lava-beds commence 

 covered with a diminutive species of broom and 

 "with small heath-like plants. 



(c) The summit of the Peak, 13,353 ft., is perfectly 

 barren except for tnfts of dark spongy moss, and 

 is composed of fresh-looking ashes. 



The forest region naturally claims the largest number of 

 species, as it also covers the greater area ; many more 

 inhabit the grass-land and plateau above the forest, while 

 several remarkable forms were discovered at the Peak itself, 

 amongst which Anthus camaroonensis may be noted. 



Amongst the English explorers who have made known the 

 wealth of Cameroon Mountain, the names of Sir Richard 

 Burton and Sir Harry Johnston, whose collections were 

 described by Gray * and Shelley f, and in later years of Boyd 

 Alexander, will stand out as the most prominent. In the 

 magnificent collection which Alexander bequeathed to the 

 British Museum almost all the rarer species are represented. 



Swedish, Austrian, and German naturalists have been busy 

 during recent years in Cameroon, and two notable scientific 

 expeditions have been at work. The first complete ornitho- 

 logical work of importance is that of the Swede, Yngve 

 Sjostedt, who has written an excellent article entitled "Zur 

 Ornithologie Kameruns^' (Kong. Svensk. Vetenskaps-Akad. 

 Handlingar, 1895, pp. 1-120). 



Dr. Reichenow has published many short papers in the 

 ' Ornithologische Monatsberichte,^ but the most important 

 contribution is the Report on the Ornithological Results of 



* Ann. Mag. Nat. Hist. vol. x. 1862, pp. 443-445. 

 + P.Z. S. 1887, pp. 122-120.
