 Pitangus taylori Sclater.) 



Rather large Tyrannidse (wing about 100-115 mm.), similar in gen- 

 eral structure to Pitangus Swainson, but difTering in broader and more 

 depressed bill (its width at posterior end of nostrils equal to more 

 than half the distance from nostril to tip of maxilla and one and a half 

 times its depth at same point), with longer gonys (very nearly twice to 

 more than twice as long as mandibular rami), longer tail (much more 

 than four-fifths as long as wing), much longer tenth (outermost) 

 primary (longer than fourth instead of equal to or shorter than 

 first), more exposed nostrils, more scant and conspicuously bristly 

 latero-f rontal feathers, larger rictal bristles, and very different style of 

 coloration (under parts grayish white instead of yellow, no wliite 

 superciliary stripe, etc.). 



a ToXfia, bold, daring; apx6<;, a ruler, chief, or leader.
