Adult male and female are similar in colour of plumage. 



Three examples, from the Mazaruni River, Bonasika River, and 

 Supenaam River, which are apparently adult, have the chin and 

 throat for the most part v/hite and the chestnut on the upper surface 

 not quite so bright. A specimen from Anarica River is similar, 

 but the feathers on the lower flanks have buffy-white tips, which 

 gives a barred appearance. 



Two others, one from Mount Roraima and another fi-om Kama-

 duller, abdomen much paler, inclining to dull white, and the upper 

 wing-coverts tipped with buff as also the lower flank-feathers. 



Young. Has the head slate-grey with a tinge of buff inter- 

 mixed ; back and upper wing-coverts warm brown with bright
