latter forming a distinct ascending point; gonys much more than half 
as long as mandibular rami, the distal width of the interramal space 
about equal to its length. Nostril oval (narrower anteriorly), longi- 
tudinal, overhung by a broad operculum. Rictal bristles minute or 
obsolete, but feathers of loral, malar, and mental antiz with distinct 
antrorse bristly tips, those of the chin more slender and strongly 
recurved; loral feathers normal; feathers on sides of occiput (supra- 
auricular region) elongated, very slender, forming a narrow, filamen- 
tous tuft; middle wing-coverts very large, very broadly rounded; 
upper tail-coverts elongated, distinctly outlined, those of the adult 
male reaching to beyond middle of tail, broadly rounded terminally. 
Seventh primary longest, the sixth a little shorter, the tenth less than 
half as long as seventh. Tail shorter than wing, graduated for more 
than one-third its length, the rectrices rounded at tip, the lateral 
ones perceptibly narrowing terminally; tarsus decidedly shorter than 
longest toe, feathered for upper portion. 
Coloration.—Chest and upper parts, including wing-coverts, metallic 
green, the middle rectrices glossy blue-black, the remiges slaty; 
lateral rectrices broadly tipped with white; breast, abdomen, and 
under tail-coverts red; adult female similar, but with head and chest 
slate-grayish.

wing-coverts bright metallic green to greenish bronze, passing into 
bright bluish green on rump and upper tail-coverts; six middle rec- 
trices and basal portion of lateral rectrices dark metallic blue, the 
three lateral pairs of rectrices broadly tipped with white, this occu- 
pying the terminal third (approximately) on outermost rectrix; 
remiges and greater and primary wing-coverts slate-blackish, the 
greater coverts and secondaries (especially the former) more or less 
distinctly margined (narrowly) with metallic green, the outer webs of 
primaries (except innermost) more grayish, passing into grayish 
white basally; middle and lesser wing-coverts abruptly slate-blackish 
basally, this largely exposed; chest bright metallic bronze-green, 
passing into a more bluish hue toward blackish of throat; rest of 
under parts bright, pure red (geranium red), the thighs dark slate 
color; bill bluish gray for basal half or more, blackish terminally; 
feet horn color or dusky (in dried skins); length (skins), 320-351
