VOL. viii] B.O.U. LIST OF BRITISH BIRDS. 279 



it has been the united aim of zoologists during the last few 

 years to attain uniformity by means of rigid priority, much 

 attention and study has been bestowed vipon the subject in 

 many quarters. 



It will be convenient to divide the differences in the names 

 used in the two lists into various groups, which may be dealt 

 with separately. First let us take the names, whether 

 specific or generic, which we are agreed to accept and alter in 

 our Hand-List. All these alterations are in accordance 

 with the Rules and Opinions of the International Commission. 

 These are as follow, the name which we accept being in 

 small capitals, and the name rejected in italics, while the 

 numbers refer to the Hand-List. In the next issue of British 

 Birds, which commences a new volume, we shall give a list 

 of all alterations in the Hand-List with brief reasons, and the 

 names of the Hand-List so altered will be used in British 

 Birds from that date.
