This is another species taken on the Caura River by both Andre 

 and Klages but one that I did not see on the Orinoco proper. Miller and 

 Iglseder have recently taken examples at the foot of Mount Duida.

In the Miller and Igleseder collection made near the foot of Mount 

 Duida, Upper Orinoco (Am. Mus. collection), is a single specimen that 

 probably pertains to this race. 



This specimen, an apparently adult female, taken Mch. 3ist, is 

 dark citron green above, the feathers of the crown and nape showing 

 much slate grey basally and centrally (the feathers of the nape and 

 crown might be said to be slate grey heavily bordered with the color 

 of the back) : ear-coverts pale brownish drab. Below grey, dark 

 neutral grey on throat and upper breast, pale neutral grey on sides and 

 flanks, centre of breast, abdomen and under tail-coverts very pale grey ; 

 sides of neck, throat and breast washed lightly with color of back 

 throat and upper breast faintly washed with buffy. Axillaries, under 

 wing-coverts and narrow inner edges of wing-quills lemon yellow. Wing 

 56 mm., tail 45 mm. 



There is no indication of the olive green jugular band of P. m. 

 muscicapina.

 by Miller and Igleseder.
