M. Taezanowski has most kindly sent to me for exami- 

 nation the unique type specimen of this species^ which was 

 obtained at Monterico^ in Central Peru, by Jelski in 1872. 

 Although somewhat resembling H. thoracicus in the colour 

 of its cap (which, however, is not pure cinereous, but rather 

 ashy brown), H. flaviventris seems to me to come nearest to 

 H. fuscicapillus and H. aurantiifrons, and to go best in the 

 present section.

Mr. Buckley^s specimens are the only examples yet known 

 to me of this distinct species.
