TTEANNID^ — THE TYEANT FLYCATOHEES. 843 



more elongated, less depressed, the outlines straighter, while there 

 are various other differences. Upon the whole, the genus may be 

 considered quite a natural group. 



The species vary among themselves not only in colors, but in 

 other respects also, each one having'its own peculiarities of external 

 form, so that were all identical in'coloration they could even then be 

 readily distinguished. Attempts have been made to subdivide the 

 genus, but all have proved unsatisfactory. There is, truly, a vast dif- 

 ference in size and form between the robust, almost gigantic, T. magni- 

 rostrls, and the little T. aurantio-atrocristatus ; but as other species are 

 variously intermediate, it seems best to consider the variations of 

 form and size in this genus as of mainly specific importance. 



The single eastern species and two western ones which may be 

 expected to occur in Illinois differ from one another as follows : 



A. Lower parts white, upper parts blackish. 



1. T. tyrannus. Wings black, feathers taargined with white. Tail black, sharply 

 tipped with white. 



B. Lower parts yellow, ashy anteriorly; upper'parts ashy-olive. 



2. T. vertioalis. Wings brownish dusky, feathers indistinctly edged with paler. 

 Tail deep black, the outer webs of lateral feathers pure white, in abrupt contrast. 

 Throat and jugulum pale ashy-gray. 



a. T, vociferans. Wings light brownish gray, the feathers with paler edges. Tail 

 dull black, the tip dull grayish, as are alsojthe outer webs of .the lateral feathers. 

 Throat and jugulum deep slate-gray.
