U. S. p. It. K. EXP. AND SURVEYS — ZOOLOGY — GENERAL REPORT, 



shorter than the middle ones. The fourth quill is longest ; the first shorter than the fifth. 

 The legs are long and of a yellow color. 



I have not found any specimens of this species agreeing with the Trichas personaius of Swainson 

 as distinguished from his T. hrachydacfylus. All before me have the short lateral toes dis- 

 tinguishing the latter species. Should, therefore, there be really two, as suggested by Swainson, 

 the new one will be that to which he has assigned the name of personaius. 



Among the specimens before me are several males in autumnal or winter dress in which the 

 entire crown is pale reddish olive, except a very narrow black frontlet. The black of the cheeks 

 is also considerably obscured. This agrees with the Sylvia roscoe of Audubon. There is a 

 slight trace only of the conspicuous white ring round the eye, shown in the figure of roscoe, 

 this is characteristic of the female ; nor is the olive of the back so dark. 



Specimens from the west appear larger than eastern ones, and the hoary suffusion back' of 

 the black on the head is more sharply defined and whiter. One skin from Racine has the 

 belly yellower than usual, and thus more like G. velatns. 



This species is readily distinguishable from G. macijllUvrayl and ])hlladeJphia in the adult 

 dress. The female and immature specimens of the latter may be distinguished by the bright 

 yellow of the whole under surface of body and tail coverts, and the gray tinge on the neck and 

 throat without the decided yellow of G. trichas.
