PREFACE. 





IN the following Catalogue, the Author has endeavoured to 

 replace the names of the older Writers on Ornithology ; 

 thinking, that although the generic name may have been 

 altered, in any case, with sufficient reason, by modern Authors, 

 it is no reason why the specific should, unless, from a change 

 of gender in the generic or subgeneric appellations, or for 

 some other good cause, it becomes necessary. He thinks, 

 however, it would be much better to suit the new generic 

 names to the old specific ones, than to alter the latter to suit 

 the former. 



He thinks also, that changing the generic application, does 

 not give an Author the right of placing his name, or the words 

 Mihi and Nobis after the specific name given by an older one. 



The arrangement of the Catalogue is nearly that of the Baron 

 Cuvier, published in the last edition of the " Regne Animal." 

 Alterations, however, occur in the arrangement of the Families, 

 in the order Passeres, among the Gulls, and in the order Lamelli- 

 rostres.
