* Acting on Professor ]S T ewton’s suggestion, I havo substituted albicapilla for albicilla ; for the bird is white-headed and not 
white-tailed, and I cannot believe that Lesson ever intended to apply the latter name to it. Although it has hitherto been the 
practice to use it, I think I am justified in rectifying what was obviously a lapsus calami.
