Adult (No. 88457, Bogota; obtained from Count von Berlepsch). — 

 Pileuui deep bistre, this color gradually fading on hind-neck, back, 

 scapulars, and lesser and middle wiug-coverts into raw-umber brown, 

 with a slight tawny tinge, the pileum and hind-neck very narrowly

 wiug-coverts tawnj'" brown or raw-utnber, like back, their inner webs 

 chestnut (a little lighter than tail), the outer webs of exterior primaries 

 incliniug to raw-umber, the terminal portion of inner webs of seven 

 outer quills dusky brown. Lores, suborbital region, and auriculars 

 buff, the latter sparsely streaked with dark brown, this more ex-

*The young specimen was at first, before the description was published, made the
