Mr. D. A. Bannerman on the 



stands so boldly above the snrrounding pinnacles that the 

 descent seems unbroken, giving to the whole the appearance 

 of one vast mountain rising from a single base^ although a 

 peak, about two miles inland and seven miles N.W. of 

 Ambas Bay, named Little Cameroon, rises to a height of 

 5728 feet." 



As might be expected, the avifauna of Cameroon Moun- 

 tain is closely allied to that of the highlands of Fernando 

 Po, but many species are peculiar to each locality. The 

 number of forms which have been described as new from 

 Cameroon Mountain is remarkable, and of these no less than 

 33 are represented in the present collection, e.g. : — 



19. Bradypterus camerunensis. 



20. Poliolais alexaiideri. 



21. Prinia epichlora. 



22. Laniarius atroflavus. 



23. Dryoscopus angolensia 

 o-risescens. 



1. Francolinus camerunensis. 



2. Columba arquatrix sjostedti. 



3. Haplopelia simplex inornata. 



4. Mesopicus jolinstoni. 



5. Campothera tullbergi. 



6. Psalidoprocne fiilijrinosa. 



7. Alseonax mm-iuus olscurus. 



8. Trochocercus albiventris. 



9. Cryptolopha" camerunensis. 



10. Graiicaliis caesius preussi. 



11. Bleda poliocephala. 



12. Bleda tephrolifima. 



13. Turdinus monachus. 



14. Turdus nigrilorum. 



15. Turdus crossleyi. 



16. Oossypha isabellae. 



17. Saxicola salax pallidigula. 



18. Cisticola discolor. 



24. Zosterops stenocricota. 



25. Speirops melanocepbala. 



26. Cinnyris oritis. 



27. Cinuyris preussi. 



28. Antbus camaroonensis. 



29. Poliospiza burtoiii. 



30. Pyromelana xantbomelas 



pboenicomera. 



31. Sycobrotus tepbronotus. 



32. Heterbypbantes melanogaster. 



33. Onycbognalbus preussi. 



Of these the majority appear to be restricted to the type 

 locality and the immediate neighbourhood. 



Zones of Vegetation. 

 Unfortunately Alexander does not give a very clear 

 account of the vegetation zones, which in a mountain of 

 over 13,000 feet must be very marked. I have, however, 

 found a short description, written by Sir Joseph Hooker *, 

 from which some idea may be formed, and from which I
