150 Mr. Swainson on two new Genera of Birds, 



removed into this group. Indeed, their general habit seems inter- 

 mediate between the Thrushes and the Warblers of Linnasus. 

 Like the Thamnophili they are only found in the hotter parts 

 of America: from those birds they are readily distinguished by 

 their more slender and somewhat rounded bill ; and by the length 

 of their tarsi, the lateral scales of which are in one entire piece. 

 The little that I was able to learn of their economy, leads mc to 

 suppose they principally search for food upon the ground ; their 

 legs are consequently long, and, in some species, rather strong. 

 They seem. to prefer the deep and secluded recesses of the virgia 

 forests; and in all probability derive their chief sustenance from 

 the myriads of Ants which there abound.

^ Description. 



This is certainly the most elegant bird of this group we are yet 

 acquainted with. The two sexes differ so much, that their de- 

 scriptions, in some measure, must be distinct; while those charac- 

 ters common to both, are at once seen in the specific character. 



Male. Size rather less than the Robin. The bill is black, and 

 "but little compressed. The ground colour of the upper plumage^
