is two lines, and the third two lines and a half shorter than the second; the fourth is four lines 

 and a half shorter than the third ; and the following ones decrease in succession a quarter 

 of an inch each. The second and third have their outward webs obliquely, but distinctly 

 sinuated ; and the inner webs of the three first are slightly narrowed towards their points. 

 The tips of these three feathers are comparatively broad, as they want the deep and sudden 

 sinuation so remarkable in the same feathers of the King-bird. The secondaries are very 

 obtuse, but their ends are not scolloped or emarginated, as in the King-bird. The tail is 

 forked, the central pair of feathers being more than a quarter of an inch shorter than the 

 exterior ones. Tarsi short. Nails like those of T. intrepidus, the hind one rather larger 

 than the middle one.

Of the habits of this bird little is known. It was discovered by Mr. Titian 

 Peale, on the Arkansaw River, within twenty miles of the Rocky Mountains, and 

 first described and figured by the Prince of Musignano in the work above quoted. 

 Mr. Peale informs us that its voice is somewhat different from the Peewee (Musci- 



* We received a specimen of this bird from Mexico, and designated it by the name of Tyrannula pallida, before 

 the first volume of Prince Charles Bonaparte's American Birds had reached this country. But we feel pleasure in 

 relinquishing our former specific name, and adopting that which commemorates the valuable services and diversified 

 labours of one of the first zoologists in America. — Sw. *
