tail feather exceeds the shortest hy about .21 of an inch. The innermost tail feather is 

 very broad; a little longer than the lower coverts. 



In the female the tail feathers are still more curved, and considerably broader, and more 

 rounded at the end, but still decidedly lanceolate, not linear. The tail, instead of being deeply 

 forked, is oply slightly emarginated ; the outer feather rather shorter than the second. The 

 greatest width of the outer feather is about .26 of an inch. 



In the male the entire upper parts, (including the crown,) with the sides of the body along 

 the wings, are of a rich metallic green. The metallic scale-like feathers of the chin and throat 

 are of a bright ruby red. These extend from the base of the bill (where the color is quite dull) 

 over the throat, the ^josterior lateral ones not projecting more than .15 of an inch behind the 

 middle ones. Immediately posterior to the metallic gorget is a collar of dirty white, which is 

 continued along the median line, where it is tinged with brown, to the tail coverts, the centres 

 of which show a little metallic green, and the exterior a little pale rufous. There is a rather 

 purer white around the legs, and a very indistinct spot of the same just behind the eye. The 

 tail feathers are uniform brownish purple ; the wings are similar, with less purple. 



The adult female is similar to the male in the colors of the back and wings, with the white 

 spot behind the eye. The entire under parts are of a dirty white, tinged with brownish on the 

 throat and sides. The outer three tail feathers on either side have their central third of a 

 purplish black ; the terminal portion white. The fourth feather is black at the end, with a 

 very slight white tip. In all, the basal half of the upper surface (and of the lower in the 

 fourth) is green like the back. The innermost has an indistinct subterminal bar of blackish. 

 There is no rufous on any part of the tail feathers in either male or female. 



The young male is like the female beneath, except that the throat feathers are spotted in the 

 centre, and some show a trace of the metallic red. The tail is mostly like the male.
