GENUS TROGLODYTES VIEILLOT. 



Troglodytes VIEILLOT, Ois. Am. Sept. ii, 1807. 52. Type, T. aedon VIEILL. 



Anorthoura RENNIE, Montagu's Orn. Diet 1831. Type, Motacilla troglodytes LINN. 



The characters of this genus are sufficiently indicated in the synopsis on page 89. 

 They come very close to those of Thryolhorus, the nostrils, especially being linear and 

 overhung by a scale. In this respect both differ from Thryophilus of Middle America. 

 The bill is shorter or not longer than the head; straight, slender, and without notch. The 

 tail is graduated, and shorter than the much rounded wings, the feathers narrow. The 

 light superciliary line of Thryothorus is almost entirely wanting in the North American 

 species. 



Our two species may be thus distinguished: 



a 1 . Bill rather stout, with decidedly convex culmen. Tail nearly or quite as 

 long as wing. Beneath brownish white, the crissum and flanks barred 

 with dusky and rusty T. aedon. 



a 1 . Bill slender, the culmen nearly straight. Tail decidedly shorter than wing. 

 Beneath pale brown, whole abdomen, sides, flanks and crissum barred 

 with dusky T. hyemalis.
