lengthened feathers on the chest white, one has the rump 

 green and the other purple, both have considerable cinnamon 

 color in their tails. 



The one now described, can readily be distinguished from 

 all, by its olive-colored tail.

The crown is of a dull brown without lustre, remainder of upper 

 plumage of a shining dark grass green ; central tail-feathers of a dark 

 rather dull bronzy green, the others greenish at base with a broad

 most in extent on the outer feathers; the smaller and middle wing 

 coverts colored like the back, the larger coverts dull purple, the 

 quills purplish brown; the entire under plumage is of a dull grayish 

 brown color, with an ochreous tinge ; sides dull green with a white 

 pleural spot ; under tail coverts dull green, with grayish margins ; 

 bill black ; feet pale yellow.

Remarks. — This is much the largest of the genus, and seen s 

 to differ from all its allies in the absence of brilliant coloring; 

 on either the crown or throat ; I think it is certainly adult, 

 and not an immature bird ; all the young birds of the other 

 species of this genus, examined by me, have their throats 

 black before the brilliant colors are developed ; judging from 

 analogy, I conclude therefore that this species does not possess 

 a brilliant throat ; the sex is not given, it may be a female and 

 the male may have a shining crown, but in this specimen 

 there are no indications of any ; it is also without the longi- 

 tudinal white mark on the rump, the white spot behind the 

 eye, and the stripe of a similar color on the side of the throat, 

 existing in all the others.
