to somewhat flattened beneath, where usually with a more or less 

 distinct median ridge, the produced, chisel-like tip abruptly beveled, 

 with truncate or faintly concave terminal margin, which is more or 

 less distinctly concave on upper side. Wing moderate, the longest 

 primaries exceeding distal secondaries by about two-fifths the length 

 of wing; seventh, eighth and ninth, or eighth, ninth, and tenth pri- 

 maries longest, the tenth (if shorter than ninth) equal to or shorter 

 than seventh; tip of seventh primary not attenuated. Tail decidedly 

 shorter than wing to very nearly as long, graduated for about half 

 its length, the rectrices more or less distinctly tapering terminally, 

 with tip broadly rounded (except, sometimes, middle rectrices, which 

 however, are never acute at tip). Tarsus equal to or shorter than 

 outer hind toe without claw. 



Plumage and coloration. — Cere wholly, or for greater part, naked, 

 the nostrils conspicuously exposed; orbital region extensively naked; 

 feathers of foreneck and chest usually sharply defined. General 

 color green, the under surface of tail dull red or dusky reddish brown; 

 foreneck and chest usually barred or squamated with pale yellowish 

 or pale buffy brownish; primaries usually blue; abdomen often dull 

 red.

 distinctly margined or streaked with wax yellow, those of foreneck 

 sometimes (but more rarely) similarly marked; short downy feathers 

 of lower chin reddish; auricular region (at least in part) dull vermilion 

 or poppy red, the feathers with paler (more yellowish or orange- 

 colored) shafts; outer (distal) greater wing-coverts and middle sec- 

 ondaries canary yellow for anterior portion, sometimes along edges 

 also; alulse and primary coverts canary yellow, with terminal por- 

 tion dull green or greenish dusky; primaries more bluish green (espe- 

 cially the outermost ones), with shafts and terminal portion of inner 

 webs blackish; tail more olivaceous green (especially middle pair of 

 rectrices), with black shafts, the under surface reddish dusky passing 

 into light brownish red on edges of inner webs; smaller under wing- 

 coverts green; under primary coverts canary yellow with distal por- 

 tion (broadly) olive-slaty; inner webs of remiges canary yellow proxi- 

 mally, olive-dusky distally, the yellow becoming more olivaceous
