INTRODUCTION TO BIRDS. 
Five and twenty years having elapsed since the publication of a catalogue of 
the birds of our county, and many enquiries having been made for one, the 
author has ventured to undertake the task. In its compilation he has had 
the valuable assistance of J. Gatcombe, Esq., a gentleman whose thorough 
acquaintance with the birds of Great Britain, is well known to ornithologists. 
The list of Dr. Moore, published in 1837, in Louden's Magazine of Natural 
History, vol. i., N.S., was an admirable one, but many additions to our Avi- 
fauna have since been made. 
The author has thought it unnecessary again particularly to refer to the 
instances of the occurrence of the rarer birds mentioned by Dr. Moore, as 
with regard to many (several of the Accipitres for instance), no information 
is forthcoming beyond that furnished by him. 
The scientific arrangement, proposed by Professor J, H. Blasius, 'in his 
recently published List of the Birds of Europe, has been adopted, as well as his 
nomenclature. The English names are those found in Gould, Yarrell, and 
Morris.
