in number, the ground color appears to be a pale bluish as well 
as grayish green in some cases, which undoubtedly has faded to a 
certain extent. This ground color is occasionally almost entirely 
hidden and overlain by a uniform brownish suffusion of different 
degrees of intensity ranging from Prout’s to chocolate brown (see 
Ridgway’s ‘Nomenclature of Colors’), giving such eggs an evenly 
colored appearance resembling somewhat the darker colored 
phases or types found most commonly in the eggs of Calcarzus 
lapponicus. About ten per cent show this pattern. Eggs in 
which the ground color is plainly and readily perceptible, are 
irregularly blotched and speckled to a greater or less extent with 
various shades of chocolate, umber, and vandyke brown, ecru 
drab, cinnamon rufous, and lilac gray. The difference in these 
eggs, as regards their markings, is very great, scarcely any two 
out of different nests being exactly alike. The largest egg in the 
number before me measures 1.00 X .68 inch, the smallest .80 x 
.61 inch. The average is .80 X .63 inch. 
The distribution of the Fox Sparrow during its migrations is 
well enough known, as well as its general habits while with us as 
a winter visitor. I took a single specimen, a female, on Oct. 8, 
1885, at Fort Custer, Montana, which I believe marks about the 
western limit of its range, during its migration. The specimen 
showed scarcely any trace of rufous, but was, on examination by 
Mr. Robert Ridgway, referred by him to this species. It is now 
in the collection of Mr. Manly Hardy, Brewer, Maine. 
Il. Passerella iliaca unalaschcensis (Gmel.), TowNsENp’s 
SPARROW. 
This bird was first described by Gmelin in 1788, under the 
name of Emberiza unalaschcensis, and seems to be confined in 
its habitat to the Pacific coast region, breeding, as far as is known 
at present, throughout British Columbia and Alaska Territory, 
and passing in its migrations well into southern California. Till 
recently it was supposed to be confined to the western slopes of 
the Cascade Range in Oregon and the Sierra Nevada in Calitor- 
nia, but I found it abundant at Fort Klamath, Oregon, on the 
eastern slope of the Cascades, during the fall of 1882, and spring 
of 1883, but did not find any evidence of its breeding there, and 
am inclined to think that it is only a migrant. A number of
