EUPETOMENA. 



21 



The birds composing the three following genera arc characterized by having the 

 shafts of the primaries more or less developed, and in the males these are broad and 

 flattened. The majority of the species have a portion of their plumage composed of 

 metallic feathers. The genera are mainly distinguished by the shape of the tail, 

 this being long and deeply forked in Eupetomena, cuneate in Sphenoproctus, and 

 rounded in Campyloptekus. Having been unable to perceive any satisfactory 

 generic characters to separate cuvieri and rohertl from Camptlopterus, I havo 

 kept them in that genus, the fact that the shafts of the primaries are less flattened 

 than is observed in other species of the genus not being sufficient, in my opinion, to 

 cause their removal to a distinct one.
