310 PARKMAN'S WREN. 



and toes are propoi'tionally larger. The colours are, however, similar ; 

 but the present species has no whitish band margining the black band on 

 the head, and this latter band is much narrower in front, and does not 

 proceed so far down the neck, extending only to the distance of four and 

 a half twelfths from the eye, whereas in S. Trichas it extends to the 

 distance of half an inch. 



PARKMAN'S WREN 



Troglodytes Parkmanii. 



A single specimen of this Wren which differs considerably from 

 Troglodytes hyemalis and T. europoeus, has been sent to me by Dr 

 TowNSEND, who procured it on the Columbia River, along with 

 several others, all exactly similar. The principal difference is in 

 the bill, which is much longer, stouter, and decidedly arched. The 

 wings also are considerably longer, as is the tail in a still greater de- 

 gree. The plumage is similar, and presents nearly the same markings, 

 but the colours are much paler, and the lower parts nearly greyish- 

 white. This, however, may be merely the effect of the weather. This 

 species may be briefly characterized as follows : 



T. Parkmanii. The bill much longer, stouter, and more curved 

 than that of T. hyemalis ; the upper parts reddish-brown, faintly barred 

 with dusky, the lower parts dull brownish-white ; the sides barred with 

 brownish-black, and greyish-white, the foreneck and breast with scarce- 

 ly any markings, the lower wing-coverts and axillars greyish-white ob- 

 scurely barred with dusky ; the tail half an inch longer than that of 

 the common species, and more rounded. 



Bill rather long, slender, tapering ; as broad as high at the base, 

 slightly arched, compressed toward the end. Upper mandible with the 

 dorsal outline slightly arched, the ridge narrow, the sides sloping at 

 the base, toward the end slightly convex and erect, the edges sharp, 

 direct, without notch ; lower mandible with the angle narrow and ra- 

 ther acute, the dorsal outline decurved in an almost imperceptible de- 

 gree, the back narrow, the edges sharp and inflected, the tip very nar- 

 row ; the gape-line slightly arched. Nostrils oblong, basal, operculate. 



Head ovate, of moderate size ; neck short. Feet of ordinary length ; 

 tarsus compressed, with seven anterior scutella, all of which are very
