The specimen from which Audubon described his Troglodytes heincldi 

 came from near St. Frajicisville, Louisiana, and his plate and desciiption 

 clearly indicate that this name belongs to the form of Thrijomanes 

 inhabiting the eastern United States. This race is readily to be dis- 

 tinguished from all the other forms of the genus by the rich burnt 

 umber brown of the upper parts. 



The characters of heicicMi are very constant, the ])rinci])al variation 

 being a seasonal one. Summer specimens are ijaler and grayer than 

 examples taken in fall or winter, this ditt'erence being ]iroportionate to 

 the amount of wear to wiiicli tlie plumage has been subjected. .The 

 bird is always, however, easily distinguishable from cryptus, which 

 these worn specimens somewhat resemble. 



Two March specimens from Waukeenah, Florida, are duller and rather 

 more grayish than other specimens of corresponding season, but are 

 not otherwise different. Two examples from Texas — one from Waller 

 County, the other from Brazos — are in every respect perfectly typical 

 of hewielii. 



A series of young birds exhibits a striking range of variation in the 

 shade of the upper surface — from a dark sooty brown to a pale rufes- 

 cent color; but the average is more reddish than in any of the other 

 forms. 



There appears to be no record of Bewick's wren for New York State, 

 New England, or any part of the region north of the Great Lakes; and 

 throughout the northern portion of its range it seems to be only locally 

 common. There seems to be no account of its breeding in Florida, or 

 in the Gulf region of any of the Southern States. 



Thirty-four specimens of this form have been examined, these repre- 

 senting the following localities, breeding records being indicated by 

 an asterisk:
