a little bent, grooved, and pointed ; tlie upper mandible, bluish 
black ; lower, light blue ; nostrils, oval, partly covered with 
a prominent convex membrane ; tongue, pointed and slender ; 
eyes, hazel; tail, cuneiform, the two exterior feathers on 
each side three quarters of an inch shorter, whitish on their 
exterior edges, and touched with deeper black ; the same may 
be said of the three outer primaries. The female wants the 
white on the wing-coverts ; but differs little in colour from the 
male. 
In this species I have observed a circumstance common to 
the House and Winter Wren, but which is not found in the 
Marsh Wren ; the feathers of the lower part of the back, 
when parted by the hand, or breath, appear spotted with 
white, being at bottom deep ash, reddish brown at the surface, 
and each feather with a spot of white between these two colours. 
This, however, cannot be perceived without parting the 
feathers.

The habits of this beautiful species, like those of the 
preceding, are not consistent with the shape and construction 
of its bill ; the former would rank it with the Titmouse, or 
* As with many others, there has been some confusion in the synonyms of 
this species, and it has been described under different names by the same 
authors. That of flavicollis adopted by our author, is characteristic of the 
markings ; whereas pensilis of Latham and Vieillot is applicable to the whole 
group ; and perhaps restoring Wilson’s name will create less confusion than 
taking one less known. The genus Sylvicola, with the sub-genus Vermivora ,
