Gexus troglodytes Vieillot. 



Troglodytes Vieillot. Ois. Am. Sept. ii, 1807. hi. Type. T. aedon Vikill. 

 Anorlhoura Renme. Montagu's Orn. Diet, ISU. Type. Molacitla troglodytes Linn. 

 The characters of this genus are sufficiently indicated in the synopsis on page 8!>. 

 They come very close to those of Thri/othorus, 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 Thryolhorus is almost entirely wanting in the North American 

 species. 



Our two species may be thus distinguished : 

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

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



with dusky and rusty T. aedon. 



a": 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.
