Small Phalerine (wing 103.5-116 mm.) with bill small, without 
obvious deciduous accessory pieces, the culmen strongly convex; 
adults in breeding season with a long and slender recurved frontal 
crest, filamentous, recurved superciliary plumes, and elongated 
filamentous or slenderly acicular plumes from rictus across cheeks 
and from lower-posterior margin of eye across auricular region. 
Bill relatively small and stout, the strongly arched culmen less than 
half as long as tarsus, its width at frontal antia decidedly less than its 
depth at same point, and about equal to distance from nostril to tip 
of maxilla; gonys nearly straight, strongly inclined upward toward 
tip, about as long as distance from nostril to tip of maxilla, its base 
forming a prominent angle; maxillary tomium nearly straight except 
near base, where distinctly recurved, distinctly notched subterminally; 
mandibular tomium straight, faintly notched terminally; nostril 
longitudinal, narrowly ovate or nearly linear, in extreme lower edge 
of nasal fossa, overhung by a broad corneous or semicorneous oper- 
culum with reflexed lower edge; frontal antia more anterior than 
posterior end of nostril (but posterior to middle of the latter), not 
indented at base of culmen; malar antia nearly on vertical line with 
posterior end of nostril, the mental antia about on line with middle of 
nostril. Wing rather small, the longest primaries (two outermost) 
exceeding distal secondaries by less than half the length of wing. 
Tail slightly more than three-sevenths as long as. wing, slightly 
double-rounded (the lateral and middle pair of rectrices about equal 
in length); rectrices 14. Tarsus a little shorter than middle toe 
without claw, the acrotarsium reticulate; outer toe (without claw) as 
long as middle toe (without claw), the inner toe as long as first two
