parts neither bright yellow nor streaked; no superciliary

/. Bill broader and mf)re depressed basally, its width at frontal 



antise equal to much more than half the length of 



exposed culmen; tarsus nearly if not quite twice as long 



as middle toe with claw Sublegatus (p. 418) 



//. Bill narrower and deeper basally, its width at frontal antiae 

 not more than half the length of exposed culmen; 

 tarsus much less than twice as long as middle toe with 



claw Elaenia (p. 423) 



H". Tarsus little if any longer than middle toe with claw; under 

 parts (>ither bright yellow or streaked; a white super- 

 ciliary stripe or else ( Tyrannopsis) a yellow concealed 

 crown-patch; a concealed crown-patch of yellow, orange,

 I. Bill shorter and much broader, its width at anterior end of 

 nostrils at least equal to length of gonys and twice its

streaked with grayish Legatus (p. 438 i 



//. Bill longer and narrower, its width at anterior end of nos- 

 trils much less than length of gonys and much less than 

 twice its depth at same point; under parts bright yellow,

 7?). Bill relatively much smaller (about half as long as head, 

 the exposed culmen little if any longer than middle 

 toe without claw), much narrower, its width at anterior 

 end of nostrils equal to much less than half the length 

 of exposed culmen, and little if any more than its 

 depth at same point; nasal fossa? narrower and oval 

 anteriorly, the nostril midway between tomium and 

 culmen, with overhanging membrane scarcely wider 

 than nasal opening; tail more than three-fourths as 

 long as wing; smaller (wing not more than 100 mm.); 

 a broad white superciliary stripe. .Myiozetetes (p. 442) 

 7n7n. Bill relatively much larger (about two-thirds as long 

 as head, the exposed culmen decidedly longer than 

 middle toe without claw), much broader, its width at 

 anterior end of nostrils equal to half the length of 

 exposed culmen and much greater than its depth at 

 same point; nasal fossae very broad and subtruncate 

 anteriorly, the nostril much nearer to tomium than to 

 culmen, with overhanging membrane about twice as 

 wide as nasal opening; tail much less than three- 

 fourths as long as wing; larger (wing more than 100 

 mm.); no white superciliary stripe.
