PREFACE. 



The Editors have now the pleasure of presenting to 

 their brother-members of the British Ornithologists' 

 Union the concluding volume of the Fifth Series of 

 'The Ibis,' being the thirtieth volume of the whole 

 work. 



As was arranged at the Meeting of the Members 

 of the Union held in May last, the partnership 

 between the two present Editors is now dissolved 

 with mutual regret; and c Sixth Series will be 

 commenced in January next under the sole Editorship 

 of Sclater, who asks for a continuance of the aid 

 which has, hitherto, on all occasions been so liberally 

 accorded. 



It is satisfactory to see, by the list which accom- 

 panies this Number, that out of the twenty original 

 Founders of the ' Ornithologists' Union ' in 1858, no 

 fewer than thirteen are still living, some of these 

 being still amongst the most active of its Members 

 and most frequent contributors to this Journal.
