Myiophobus Reichenbach, Av. Syst. Nat., 1850, pi. 67. (Type, Musricapa 

 nsevia Boddaert = M. fasciatus Miiller.) 



Small Tvrannidae (wing about 57-70 mm.) with basal phalanx of 

 middle toe united to outer toe for less than its entire length, acrotar- 

 sial scutella very distinct, bill much shorter than head, with distinctly 

 convex lateral outlines, outermost (tenth) primary equal to second 

 or third, tail much shorter than distance from bend of wing to end of 

 secondaries, no yelloAv on rump, but crown with a concealed spot 

 of yellow or orange-rufous and wing with two fulvous bands. 



Bill much shorter than head, depressed and broad at base, its width 

 at nostrils equal to about half the length of exposed culmen and rather 

 less than twice its de]>th at same point, its lateral outlines distinctly 

 convex beyond the middle, then more rapidly converging to the tip; 

 exposed culmen equal to or longer than middle toe without claw, dis- 

 tinctly (almost shar])ly) ridged, straight for most of its length, rather 

 abruptly decurved terminally, the tip of maxilla minutely uncinate; 

 gonys nnich longer than mandibular rami, faintly convex; maxillary 

 tomium straight, distinctly but minutely notched subterminally. 

 Nostril partly exposed, longitudinally oval or elliptical, margined 

 above by narrow membrane. Rictal bristles well developed, at least 

 two- thirds as long as bill, the feathers of chin and frontal antia? with 

 very distinct curved bristly points. Wing moderate, rather pointed, 

 the longest primaries exceeding secondaries by about length of ex- 

 posed culmen; eighth or seventh and eighth primaries longest, ninth 

 e([ual to or longer than iifth, tenth (outermost) equal to second or 

 third. Tail nine-tenths as long as wing (M. nxvius) to only a little 

 more than four-fifths as long (If. flavicans), slightly rounded or 

 double-rounded. Tarsus about one-fourth to two-sevenths as long as 

 wing, rather stout, its scutellation typically exaspidean, with acro- 

 tarsial divisions very distinct; middle toe, without claw, more than 



« One specimen (the type).
