was most zommon, apparently were typical bewickii. It disappeared in 
the early spring, but the people of town said it would come again and be 
the House Wren of the summer. As the Texas form is known to be 
abundant only a few miles southward, it seems probable that the winter 
birds are typical bewickii and the summer birds bairdi. A change of res- 
idence on the part of the author prevented the exact determination of 
the matter. At Caddo, neither Troglodytes aédon nor its western sub- 
species has been found. Mr. Lloyd states that Baird’s Wren raises two 
broods in western Texas, where it is an abundant resident.

The House Wren is a bird of the Eastern States, ranging west to the 
Mississippi Valley. In looking over the notes contributed on this 
species it bas been found necessary to cut out 35 per cent. as being of 
uncertain identity. The House Wren is so commonly confounded 
with the Winter Wren that the records of its movements are per- 
plexing and not very reliable. Information is needed concerning the 
northern limit of its winter range in the Southern States west of 
the Mississippi River. East of the Mississippi it is reported as regu- 
larly resident up to latitude 385°, and occasionally still farther north in 
heavy bottom lands. In migration, in the spring of 1884, it reached 
latitude 37° in Missouri the last week in March; latitude 38° 40/ in 
Missouri April 19; latitude 39° 19’ in Illinois April 25; and latitude 
39° 12’ in Kansas April 24. After this the advance seems to have been 
very rapid, for the species arrived at latitude 46° 33’ in Minnesota May 
3, and at Oak Point, Manitoba (latitude 50° 30’), near the limit of its 
northward journey, May17. There is quite a strong intimation that the 
wigration through eastern Illinois and Wisconsin took place from a 
week to ten days earlier than the movement in corresponding latitudes 
west of the Mississippi, but in the present uncertainty as to which 
species of Wren was actually seen no positive statement can be made. 
In the fall of 1884 the bulk of House Wrens left Des Moines, Iowa, 
August 28, and none were seen there after that date. At Shawnee- 
town, IIl., a single bird was reported as having been seen all winter. 
In the spring of 1885 the records of the House Wren and the Winter 
Wren in migration were hopelessly mixed. The two Wrens appear to 
have migrated more nearly at the same time than usual, thus increasing 
the confusion of the records. All that can be safely said of the House 
Wren is that it was one month (from April 17 to May 17) in passing 
from Saint Louis, Mo. (latitude 38° 40’), to Oak Point Manitoba (lati- 
tude 50° 30’), The A. O. U. Check-list gives the habitat of the typ- 
ical House Wren as “Eastern United States and Southern Canada, — 
west to Indiana and Louisiana.” The subspecies parkmanii is given as 
ranging in “ Western North America, from Texas, Illinois, Minnesota, 
and Manitoba westward; north to Great Slave Lake, south to Jalapa, 
Mexico, and Lower California.” According to these habitats, both of 
the localities mentioned, Saint Louis and Oak Point, belong to the
