shape; the middle pair of rectrices is but slightly lengthened and less narrowed at the tip. 
The tarsi are more slender and weaker than in Chiroxiphia; like the members of this genus, 
the scutes are sometimes almost fused.

crimson; vertex, occiput, back, tail and upper wing coverts velvety black. Quills blackish, 
tertials and outer webs of secondaries bright olive green. Lores black; sides of the head smoky 
grey; throat, and sides of the neck pale cinereous, breast and abdomen white, sides blackish, 
under tail coverts pale greenish yellow. Axillaries, under wing coverts and quill lining white. 
Adult Q : upper parts bright oil green, sides of the head and lower surface cinereous, washed 
with greenish on the chest and sides. Bill and feet pale brown.

Characters. This genus leads from Pipra to Chiromachaeris. The bill is small as in 
the members of the former genus, but rather broader at the base, thus more like Chiromachacris. 
The feathers of the upper throat are distinctly elongated, though less so than in the latter genus. 
The tail is relatively longer than in Pipra, the metatarsus slender and short, the toes very 
small and feeble. The best character to recognize the species of Corapipo consists of the shape 
of the outermost primary which is either narrowed (C. gutturalis) or much shortened (C. /eu- 
corrhoa). The first and the succeeding primaries are, however, never curved inwards as in 
the species of Chiromachaeris. Sexes different. Males glossy black with the throat white, 
females green. 
Geographical Distribution. Cayenne, British Guiana, Colombia and Central America 
as far north as Nicaragua. Only three forms are known.
