[The classification of birds here presented is based essentially upon that of 

 Prof. Lilljeborg, of Upsala (published in the Proceedings of the Zoological 

 Society of London for January, 18G0), and has been adopted provisionally in 

 the arrangement of the birds in the museum of the Smithsonian Institution. It 

 is also nearly the same as that of Dr. Sclater's Catalogue of American Birds, as 

 far as the latter extends. The name of each family has been printed in large 

 type on cards to serve as labels, and copies of any or all can be furnished at a 

 moderate price, on application. The first list includes the generally accepted 

 families of the neogaean — or new world — birds, embracing both those peculiar 

 to America and those found also in the old world, and the second list enumerates 

 the remaining, exclusively palaeogean — or old world — families.]
