Hah. — Eastern United States to Nebraska and Dakota. North to Canada and Nova 

 Scotia. Winters in the Southern States. 



Not obtained by Captain Raynolds' Expedition. 



Lieutenant Wan-en's Expedition. — 8846, Loup Fork. This single specimen, among Dr. 

 Hayden's collections, seems referable to typical aiidon. 



The T. americanus of Audubon, a supposed species, which I doubtfully admitted in 

 1868, has since been shown by Mr. Allen and Mr. Maynard to be inseparable from T. 

 aedon. It appears to represent simply. rather northerly bred birds. The several extra- 

 limital varieties of the species are not here considered; our western variety is noted 

 under the next head.

Troglodytes aedon. var. parkmanni, CoUES, Key, 1872, 87. 



Hab. — Western United States, from Nebraska and Dakota to the Pacific. 



Not obtained by Captain Raynolds' Expedition. 



Lieutenant Warren's Expedition.— 47'3i-35, 4737, 4138, 4741-43, Upper Missouri ; 5274-75, 

 Blackfoot country; 5276, Fort Lookout; 4739, Council Bluffs; 4740, Bald Island; 4736; 

 North Platte. 



Later Expeditions. — 60688-9, Green River ; 62328-9, Idaho and Montana. 



Dr. Hayclen's uumerons specimens attest the abuiidauce of this variety 

 iu the northwest. I found it to be numerous in the southwest; and, in 

 fact, it is a common bird throughout the Middle and Western Provinces 

 of the United States, where it replaces its familiar Eastern represent- 

 ative. It is impossible to separate this form specilically from aedon ; it 

 is merely a little paler (grayer), while certain supposed x^eculiarities of 

 habit are shared by T. aedon iu those unfrequented districts where its 

 ways have not been modified by contact with civilization. It is the 

 most numerous representative and the most uniformly distributed of the 

 Troglodytidcv of the West. It is especially common in the scantj' aud 

 irregular belts of timber that border tbe streams of the great ])lains, 

 and occurs everywhere in the mountains up to about 10,000 feet. Its 

 notes vary more or less at different localities, but everywhere it seems 

 to retain its pugnacious disposition, and its bold, inquisitive habits.
