specimens collected at Laredo, Tex., during the fall and winter of 1885- 
86 (The Auk, Vol. III, 1886, p. 248). More recently Mr. Lloyd has 
found it in winter in Tom Green and Concho Counties, Tex., where it 
is rare (Ibid., Vol. IV, 1887, p. 292). 
It occurs north, at least to northwestern Dakota, where it breeds. 
565. Spizella atrigularis (Cab.). [215.] Black-chinned Sparrow. 
A Mexican species, coming north to the valley of the Upper Rio 
Grande, in Texas. 
566. Junco aikeni Ridgw. [216.] [MWhite-winged Junco. 
This large Junco breeds in the Rocky Mountains, in Colorado, and 
Wyoming, and in the Black Hills of western Dakota. In winter it 
sometimes straggles east as far as middle Kansas and Indian Territory. 
In the winter of 1883~’84 it was found again by Dr. Watson at Ellis, 
Kans., so that it may be considered a regular visitant to the plains ia 
Kansas. 
567. Junco hyemalis (Linn.). [217.] Junco; Slate-colored Snowbird. 
Breeds from northern Minnesota northward, and winters throughout 
the middle belt of the Mississippi Valley. A most abundant and well- 
known bird, concerning which so many records were received that its 
movements can be traced with some degree of accuracy. In the spring 
of 1884 but four notes of its wintering were received from the region north 
of latitude 41°, They are as follows: From Morning Sun, Iowa, ‘‘ seen 
last winter;” from Coralville, Lowa, ‘“‘ was here last winter;” from 
Waukon, Iowa, “arrived October 15, a few remained all winter;” and 
from Heron Lake, Minn., “a very few were seen all winter.” In fact, 
it was not common at any place north of latitude 41°, and was not 
abundant north of latitude 40°. This must be accounted for by the 
unusual severity of the winter, as the ordinary winter limit of the spe- 
cies is from latitude 42° to latitude 43°, and one hardy individual has 
been known to pass the winter in northern Minnesota at Jatitude 47°. 
Latitude 39° is just within the true winter home of the Junco. The 
great bulk of the species in the winter of 1883-84 remained between 
latitude 39° and latitude 36°, being in that section the most numerous 
winter resident. They were hardly noticed by any of the Southern ob. 
servers. At Caddo, Ind. Ter., they were most conspicuous by their ab- 
sence; not a dozen a day were seen in town, and less than thirty in the 
timber. 
Of their spring movements there were but few irregular notes, from 
which it may be inferred that the migration was quite regular and that 
the species is an easily noticed bird. The record from Iowa and Minne- 
sota is as follows: March 14 the first one was seen at Ferry, Iowa; 
March 16 at Laporte City, Iowa; March 22 at Mitchell, lowa; March 
24 at Lanesboro, Pine Bend, and Elk River, Minn. At Minneapolis 
the first was noted March 27, but as the arrival of the bulk was recorded
