Birds of the United States.

tion of the two latter orders, containing by far the greater 
number of the birds unnoticed by Wilson, we yield to the 
wishes of our scientific friends in publishing the catalogue 
as first intended. This, as far as relates to the land birds, 
is a repetition of the Synopsis, which, when completed, will 
contain the characters and diagnoses of all the water birds 
here enumerated. 
As we have stated in the introduction to the Synopsis, 
we have admitted no species that has not been verified by 
Wilson or ourselves. Notwithstanding, we regard this cata- 
logue as complete; and if any species not mentioned here 
should be discovered, we take this opportunity of inviting 
the discoverer to communicate it to us for the benefit of 
American Ornithology. 
The left column contains the names we adopt, arranged 
according to our classification; the right refers to the work 
of Wilson when the bird is given by him, or, if not, to that 
of another author, the most eminent, or first discoverer; and 
a figure is always quoted whenever it exists. Wilson's 
species are printed in Roman characters; those published in 
my first volume in italics, and those that will appear in my 
subsequent volumes in small capitals. An asterisk is pre- 
fixed to those birds common to North America and Europe; 
and we have placed a || before those that Wilson indicated 
in his posthumous catalogue, that he may not be deprived 
of any part of the credit due to him.
