Genus NUTTALLORNIS Ridgway. 



Nutfallornifi >> Ridcway, Man. North Am. Birds, Sept., 1887, 337. (Type, Tyran- 

 nus borealis Swainson.) (See Oberholser, Auk, xvi, 1899, 331.) 



Medium sized Tyrannida> (wing about 100-115 mm.) with tail only 

 one-third as long as wing, tarsus only one-seventh as long as wing 

 and decidedly shorter than middle toe with claw, and with a con- 

 spicuous patch of white silky feathers on each side of rump. 



Bill much shorter than head, moderately broad and but slightly 

 depressed basally (its width at frontal antiffi much less than length 

 of gonys and much less than twice its depth at same point) , its lateral 

 outlines straight and converging gradually to the acute but not con- 

 stricted tip; exposed culmen about equal in length to tarsus, rather 

 distinctly ridged, straight to near tip where rather abruptly decurved, 

 the tip of maxilla moderately uncinate; gonys nearly twice as long as 

 mandibular rami, straight; maxillary tomium nearly straight, dis- 

 tinctly notched subtermmally. Nostril partly exposed, longitudinally 

 oval, without membrane along upper margin. Rictal bristles small 

 but distinct; feathers of chin with indistinct and minute recurved 

 bristly tips, those of frontal antiae with distinct setae arching over and 



«Two specimens.
