of wing with but little tinge of pinkish; crown dull ochraceous butt', 
streaked with blackish; auriculars buft'y; black of cheeks much mixed 
with butty and grayish. 
Readily distinguished from both penicillata and oreodrama by its

uniform pale cinnamon butt'. It di tt'e rs from bicornis in larger size, 
paler upper parts, more pinkish occiput, cervix, bend of wing and

coloration.
