Tonnfj birds have the crown dark duskj- chestnut without glittering 

 feathers'; the throat is chestnut, each featlier with a discal green 

 spot. 



D. iris hucl-Ic»/i, of Ecuador, is stated to have the front and sides 

 of the pileum of a more goklcn or a greenish-golden hue than is the 

 case in D. iris, which is there of a more crimson lustre. These dif- 

 ferences are not borne out by the specimens before me, which vary 

 without reference to locality. A good deal of the apparent difference 

 is due to the way the bkins are made up, thus altering the angle 

 at which the light is reflected from the feathers. 



J fab. Ecuador, Peru, and Bolivia, on the eastern slope of the 

 Andes at an elevation of C>00() to 8000 feet.
