The name vara was orginally adopted in the Check-List on the 
assumption that Syv/eva cerudea Latham was a primary reference ; 
it, however, proves to be merely J/ofaci/a cerulea Linnxus, placed 
in the genus Sy/va. As the spirit of the ‘Code’ (Canon XXXITI) 
is to ignore cases of this character (g ALLEN, Auk, 1903, 216), 
and previous rulings of the Committee have been on these lines, 
it follows that the name ceru/ea must be restored.
