Tarsus.—Measured from the center of the heel eae behind to

This paper is based about equally on the collection of the United

Chars. gen.—Similar to Bleda, but head conspicuously crested; 
throat feathers lengthened ; nuchal hairs long, not branched; bill not 
higher than broad at base, its height at base more than one-third of

ascending. 
Description.—Tail shorter than wing, but usually not less than 
five-sixths of it; throat feathers lengthened; tarsus scutellate; wing 
4% to about 5% times the length of the tarsus; tarsus not shorter 
than exposed culmen, sometimes 1% times as long; head dis- 
tinctly crested; nuchal hairs long (25 mm. or more), not branched ; 
rictal bristles long, reaching at least about half way to end of bill; 
bill stout, rather short, somewhat compressed, higher than broad 
at anterior edge of nostrils, but at base equal in height and breadth, 
or broader than high; height of bill at base more than one-third the 
length of exposed culmen; culmen curved from base; gonys only 
slightly ascending; maxillar tomium with only one subterminal 
notch; nostrils rounded oval, slightly or not at all operculate an- 
teriorly, but distinctly, sometimes broadly so posteriorly; frontal
