There is a very great difference in the length of the bill in different 

 specimens of this species. The longest (20,871) measures .75 from 

 nostril, and 1.15 from gape; while in another the bill is .15 shorter. 



I have not seen specimens of this bird from any point west of 

 Fort Tejon, although it is said to occur in the Sacramento Yalley.

Bill short, conical, high at base, not notched at tip. Culmen much curved. 

 Nostrils in anterior extremity of nasal groove ; broadly open and oval, but

 nearly as long as the middle, which are much shorter than tarsus. Wings 

 about equal to the much graduated tail. Plumage Wren-like ; uniform brown, 

 with dusky lines on wings and tail.
