1 It being apparent that Linnaeus described the N. American and not the 
S. American race, the former becomes the typical form and the name septentrionalis 
(Wied) must be dropped. 
Lack of material renders it doubtful if the examples 
found in Western S. America are really distinct, but as they certainly average larger 
and a trifle blacker I have felt it convenient to maintain the separation with a change 
of name.
