notched subterininally. Nostril mostly exposed, rather large, longi- 

 tudinally oval, non-opercnlate. Rictal Ijristles very strong, the longest 

 at least half as long as bill; latero-frontal bristles well developed, 

 extending much beyond nostrils. Wing moderate, much rounded, the 

 longest primary exceeding secondaries by much less than length of 

 exposed culmen (l)y about length of tarsus or slightly less) ; outermost 

 (tenth) primary shorter than secondaries; ninth equal to or shorter 

 than fifth ; seventh longest, the eighth and sixth slightly shorter. Tail 

 about as long as wing from bend to end of secondaries, slightly 

 rounded, the rectrices rather narrow. Tarsus much shorter than 

 exposed culmen, its scutellation typically exaspidean; middle toe, with 

 claw, shorter than tarsus, united to outer toe by slightly more than its 

 basal phalanx, to inner toe by about half its basal phalanx; outer 

 toe slightly shorter than middle, much longer than inner toe; hallux 

 about as long as inner toe, but much stouter, its claw decidedly shorter 

 than the digit; all the claws moderately curved, sharp, much com- 

 pressed. A very conspicuous and remarkable fan-shaped crest spring- 

 ing from center of crown, expanding transversely, the feathers with 

 broadly rounded and semi-decomposed tip.

 red, the feathers broadly tipped with black and dark steel blue or 

 metallic violet.
