JINCE the days of Linnzeus, that is, since i750, the 
systematic classification of Birds has undergone 
considerable changes and modifications, owing to the 

discovery of species unknown in the 18th century, 
and the numerous ornithological works which have appeared 
since that period, 
The publication of the Genera Avium will meet a known 
scientific want, and will3be invaluable for the classification of the 
As of the whole world. 
/ The success obtained by the Committee of publication of the 
senera Insectorum has induced us to make a similar attempt in 
the service of Ornithology. To this end, we have formed a Committee, 
composed of the best Ornithologists of the entire world, all of whom 
have assured us of their collaboration. 
Our publication will therefore have a scientific value as accurate 
as undoubted.
