82 Mr. D. A. Baimerman on rare Birds [Il)is, 



home in these two collections ; his remarks will he found 

 in 'The Ihis,' 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 

 ' The Ibis ' is strongly to l)e deprecated, and serves no useful 

 pur[iose whatever. I therefore gladly follow Mr. Ogilvie- 

 Grant's example, and have only mentioned tiiose 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 whicli 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 fiom the pen of 

 the late Dr. Bowdler Sharpe or Mr. Ogilvie-Grant, and last, 

 but not least, we have several extremely able [)a})ers con- 

 tributed to 'The Ibis ' by Mr. Bates himself.
