 instead of being divided into small plates.

 Hab. Central region of North America, from boundary of United States 

 southward into Mexico. Oaxaca. Extends up valley of Colorado. 



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 vilest of 

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



(3,969) Eyes dark-brown. (31,821.) Iris brown.

 Presbys, Cabanis, Mus. Hein. 1, 1850, 80. (Type P. can»yrons = preceding?) 



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 

 with a narrow membrane above. Internal lateral septum apparently revolute, 

 so as to be perpendicular to the central s'eptum, its exposed edge crossing

 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. 



I introduce the diagnosis of the genus merely to complete the
