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 rlr 
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. 
April 6, 1855.
