a distinct species, and has nothing to do with T. musculus Nanm. and its allies. It 

 stands qnite alone, bnt is perhaps nearest to T. sohtitialis and its kindred, being, 

 however, a giant form in comparison with them. 



T. VI. clarus may be known from trne i/ii/sci/liis by the following diagnosis : 

 T. muscuhis dicto maxime affinis, diftert corpore snbtus fere omnino albescente nee 

 rnfescente, corporis lateribus et tectricibus suhcandalibus solnmmodo rnfescente 

 brnnneo lavatis, his distinctius iiigro macnlatis sen fasciatis, corpore snperiore 

 etiam pallidiore magis grisesiente brnnneo distingnendus.

Mr. Hellmayr, who has studied the genus Polioptila with great care, is now 

 convinced that his P. anteocularis is untenable (Nov. Zool., lOiJl, p. 358). 

 P. sclateri is merely P. 7iigricepa in worn jilumage. Several of Cherrie's specimens 

 show broad white margins and at tiie same time narrow greyish edges to some of 

 the secondaries on the same wing.
