species of Rollers are known to science, of all of wbich Mr. 

 Dresser will give coloured figures, 



A new ' Check-list of North- American Birds and Code of 

 Nomenclature ' is announced as nearly ready for publication. 

 This is the report of the Committee of the American Orni- 

 thologists' Union, appointed two years ago to consider the 

 Classification and Nomenclature of North-American Birds. 

 It will consist of two parts — (1) the Code of Nomenclature 

 recently adopted by the A. O. U., and (2) a List of North- 

 American Birds drawn up on the principles of this code. It 

 will make an octavo volume of about 300 pages. 



Dr. W. L. Buller, as has been already announced (Ibis, 

 1885, J). 240), is preparing for the press a new and enlarged 

 edition of his ' History of the Birds of New Zealand.' It 

 will be issued in about ten large quarto parts, with coloured 

 figures by Keulemans. Dr. Buller, we believe, is himself 

 coming over to this country early in the year as one of the 

 Commissioners to the Colonial Exhibition at South Ken- 

 sington, and will, no doubt, take this opportunity of com- 

 mencing the work.
