INTRODUCTION. 



THE principal object of the present Catalogue is to give a 

 complete List of the GENERA and SUBGENERA of BIRDS, 

 with their chief Synonyma and Types : much attention has 

 been paid to the date of publication of each name. 



It commences with the ' Systema Naturae,' published 

 by Linnaeus in 1 735, and great labour has been bestowed in 

 collecting them from the various works and periodicals to 

 the present period. 



The Genera are marked by an Asterisk, and those left 

 unmarked are to be considered only of subgeneric value. 



The Genera which are not at present in the British 

 Museum Collection are marked with a dagger (f), to 

 indicate the Desiderata. 



The Catalogue has been prepared by Mr. GEORGE 

 ROBERT GRAY, Author of the " GENERA OF BIRDS," 

 who has, in that and other works, particularly directed his 

 attention to the Synonymy of this Class of Animals.
