 Myiozetetes (emendation) Sclater, Proc. Zool. Soc. Lond., 1859, 46. (Typo, Mu.s- 



cicapa cayanensis Linnaeus.) 



Medium-sized Tyrannidse (wing about 80-100 mm.), with small and 

 narrow bill (exposed culmen little if any longer than middle toe with- 

 out claw, its width at anterior end of nostrils equal to about half the 

 distance from nostril to tip, and not greater than its depth at same 

 point), tail at least three-fourths as long as wing; adults with an 

 orange or scarlet crown-patch, white superciliary stripe, and under 

 parts bright yellow, the throat white. 



Bill about half as long as head, narrow, its width at anterior end of 

 nostrils not greater than its depth at same point, and equal to about 

 half the distance from nostril to tip of maxilla; exposed culmen little 

 if any greater than length of middle toe without claw, distinctly 

 ridged, straight for most of its length, gradually but decidedly 

 decurved terminally, the tip of maxilla moderately uncinate; gonys 

 much longer than mandibular rami, more or less (usually faintly) con- 

 vex; maxillary tomium nearly straight, distinctly notched subter- 

 minally. Nostril at least partly exposed, longitudinally or obliquely 

 oval, overhung by narrow membrane, the nasal fossee narrower and 

 rounded anteriorly. Rictal bristles small but distinct, the feathers of 

 chin, malar antiffi, and frontal antise with small but distinct bristly 

 antrorse tips. Wing rather large and pointed, the longest primaries 

 exceeding distal secondaries by not more (usually decidedly less) than 

 length of tarsus; ninth, eighth and ninth, or seventh, eighth, and ninth 

 primaries longest, the tenth (outermost) shorter than fourth to nearly 

 as long as fifth. Tail more than three-fourths to four-fifths as long as 

 wing, slightly emarginate or double-rounded, the rectrices firm, rather 

 ])road, with broadl}^ rounded tip. Tarsus equal in length to middle 

 toe with claw (or sometimes ver;^ slightly longer or shorter), stout, its 

 scutellation typically exaspidean, the acrotarsial divisions distinct, 

 and outer side of tarsus without separate series of scutella on upper 

 posterior portion; middle toe, without claw, equal to or very slightly 

 longer than exposed culmen, its basal phalanx united to outer toe for 

 entire length, or very nearly so, to inner toe for about half its length; 

 outer toe, without claw, reaching to about middle of subterminal pha-
