The next genus, Chrtsuronia, has generally been placed far from its present 

 position, among such genera as A.mazilia and Eucephala. I do not perceive that 

 it has any especial relationship with these; but its difl'erent species, in the shape 

 and brilliant coloration of their tails, seem to possess an afiinity to the members of 

 Metallura, and properly belong to the small section of these birds with rounded 

 luminous rectrices. The species vary greatly from each other in their style of 

 coloration, and while certain ones have the head and breast higldy metallic and 

 luminous, others have the throat and under surface possessed of very little 

 brilliancy. — The sexes diff'er in their plumage, but, like those of the .species ol 

 Metallura, the females also have luminous tails.
