As Graf v. Berlcpsch has pointed out (Ibis, 18S3, p. 139, note), 

 the figure in the ' Planches Enlumine'es,' upon which the names 

 Muse, tyrannulus, Miillcr, and M. aurora, Bodd., were based, clearly 

 belongs to this species, with rufous inner webs to the tail-feathers, 

 which Mr. Salvin and I distinguished as erythroeereus when we first 

 became acquainted with it. I think it right, therefore, to restore 

 the oldest name to this species.
