82 Mr, D. A. Bannerman on rare Birds [Ibis, 
home in these two collections; his remarks will he found 
in 4 The Ibis/ 1917, pp. 72-90. I thoroughly agree with 
Mr. Ogilvie-Grant’s plan in not giving a complete account of 
these collections. It is quite unnecessary, and indeed a waste 
of time and space, to enumerate all the species which were 
obtained ; the constant repetition of notes and observations 
on the same species over and over again in the pages of 
4 The Ibis 3 is strongly to be deprecated, and serves no useful 
purpose whatever. I therefore gladly follow Mr. Ogilvie- 
Grant’s example, and have only mentioned those birds about 
which there is something of real interest to say which to the 
best of my knowledge has not been said before. 
Thanks to Mr. Bates, the British Museum is now very 
rich in material from southern Cameroon, and to my mind 
the time has come when the knowledge which has been 
gained from the study by various museum authorities of 
Mr. Bates’s magnificent collections should be collated in 
book form. As Mr. Ogilvie-Grant has truly remarked, 
from 1902 onwards papers on Mr. Bates’s collections have 
followed one another in a constant stream from the pen of 
the late Dr. Bowdler Sharpe or Mr. Ogilvie-Grant, and last, 
but not least, we have several extremely able papers con¬ 
tributed to 4 The Ibis ’ by Mr. Bates himself.
