APPENDIX 
EXHIBITING THE NOMENCLATURE OF THE AMERICAN ORNITHOLOGISTS’ 
UNION CHECK-LIST IN COMPARISON WITH THAT OF THE KEY, AND 
INCLUDING DESCRIPTIONS OF ADDITIONAL SPECIES, ETC. 
Notre. In the Key List, the numbering is continuous, with few exceptions, and the 
letters a, b, etc., and the terms bis, ter, etc., indicate additions to the numeration of the Coues 
Check List of 1882, which was preserved in the Key, 1884. In the Union List the numera- 
tion is necessarily broken to make the comparison with the Key column, because the 
sequence of species in the Union List is different. In the latter, a, b, c, indicate sub- 
species; extralimital species have their respective numbers bracketed ; and the daggers (ft) 
indicate the numbers of the ‘‘ Hypothetical ’’ List.
