under parts being little if at all appreciable. There is, perhaps, a stronger tendency to bars on 
the upper parts and sides. Whether these features should be considered as establishing a dis¬ 
tinct species I am not prepared fully to admit, hut adopt Audubon’s name as a provisional one 
for the western form. 
Audubon compares his T, parhnanni with T. hyemalis. The differences are, however, very 
great, and the comparison should be made much rather with aedon.

Troglodytes sylvestris, Gambel, Pr. A. N. Sc. Ill, 184b, 113, (actually refers to T. patkmanni ,"though quoting Audu¬ 
bon as above.) 
Sp. Cii.—S imilar in size and color to the T. aedon; the bill shorter, the tail more graduated. Colors throughout much 
darker ; no light line over the eye, but the sides of the head and neck much like the crown. The lores and ear coverts with 
the shafts of the feathers scarcely lighter. Length, 4.50 ; wing, 2.00 ; tail, 1.85. 
Ilab .—Eastern United States. 
If I am correct in the reference of No. 2951 to this supposed species of Mr. Audubon, it is 
very similar to T. aedon, but appears to have a shorter and stouter bill. The size and propor¬ 
tions are very nearly the same, though given by Audubon as considerably larger. The colors 
generally are considerably darker, with very little reddish : most distinct on the rump. There 
is no light line over the eye ; in fact the sides of the head and neck are almost uniform brown, 
with their upper parts being slightly relieved only by pale shafts to the ear coverts, and perhaps 
to the loral feathers. The under parts are considerably darker, the throat and breast almost 
brownish ash, the middle of the belly only whitish.
