A very distinct and remarkable bird, differing considerably from 
its nearest allies in the genus Ampelion, the most obvious distinctions 
being the strong beak and long wings of Carpodectes. The family 
Cotingide would seem to embrace more varied forms than any other 
American group, the Trochilide not excepted. The most marked 
forms will readily present themselves, such as Macheropterus, with 
its curious development of the quills of the wing-feathers ; Rupicola, 
Xipholena, Chasmorhynchus, Cephalopterus, all possessing marked 
and peculiar characters. The development of white, so remarkable 
in the plumage of the present bird, is not unusual in other members
