Obs. T. vilissimo affinis, sed abdomine flavido et fronte 

 cinerea distinguendus ; a T. improbo fronte cinerea diversns. 

 This is a species belonging to the same section of the genus 

 as T. vilissimus, having the wing-coverts and primaries edged 

 with olive-yellow, but differing from that species and from 

 T. improbus in the grey of the head extending to the base 

 of the beak. 



Mr. Whitely obtained many specimens, all of which agree 

 closely with one another.

Obs. M. flavicanti proximus, sed colore corporis supra 

 brunneo nee olivaceo et alis cinnamomeo limbatis primo visu 

 distinguendus. 



The wings of this species are marked not unlike those of 

 M. cinnamomeus ; but as the rump is coloured like the back, 

 its nearest ally is probably M. flavicans. 



Mr. Whitely obtained three specimens of this species, one 

 of which is in the collection of Count Hans v. Berlepsch.
