parts butty ochraccous, each feather with a dark brown center and 
white terminal spot, excepting;- the upper tail-coverts, which are 
simpl3" spotted distall y with black; middle rectrices dull brown, broadly 
edo-ed with l)urt'y ochraceous, and tipped with whitish; remainder of 
tail feathers ])rownish-black, margined with white; wings fuscous, the 
lesser and median coverts, the tips of primaries and iimermost second- 
aries edged with whitish, the rest of the wing margined exteriorly 
with butty ochraceous; superciliary dull white; sides of head and neck 
wdiite, mixed with brownish; lower parts dull white, the breast and 
juguluni washed with ochraceous and spotted with dusky; sides and 
flanks with scattered dusk}' markings. 
Although most closely allied to leucolmuia, this form, when typical, 
can be easily distinguished by its paler, nuich more pinkish and gray- 
ish colors above, white eyebrow, and usually very pale yellow throat. 
Many intermediate examples are exceedingly difficult to determine: in 
such cases the best characters for identification consist in the paler and 
more grayish colors of entkyuda. From ■praUcola it ditt'ei's in much 
lighter, more grayish coloration; from arcticola in decidedl}' smaller 
size, very much paler upper surface, together with a 3'ellow throat; 
from glraadl in larger size, conspicuously lighter upper parts, white 
superciliar}^ and pallid throat. 
The young of entlnjiiua^ though varying individually to a consider- 
able extent in the depth and shade of color of the upper surface, still 
in typical specimens average throughout more grayish than IciMoheum^ 
although some specimens, particularly those from intermediate locali- 
ties, are almost, if not quite, indistinguishable. Young t'ntJiy)iiia is 
so very much paler and more grajash thtin jnxiticola, both on the upper 
surface and on the chest, that specimens of both are always easily 
identifiable. It is everywhere very much paler and less brownish 
than the 3'oung of either /ujytl or al2)estris^ besides entirely lacking the 
conspicuous sutt'usion of 3'ellow about the head and throat. 
So far as is shown hy the specimens at hand, Otoeoris a/pcstrfs 
( nfhyiiiiii. occupies, during the breeding season, a rather restricted 
area in North Dakota, Assiniboia, Saskatchewan, and possibl3Mvestern 
Manitoba, fflling a gap between the ranges of prattcola^ fi'>yti^ and 
leucolcBma. In North Dakota and extreme eastern Montana it inter- 
grades with h'ucolcBiim. The winter range of enthymia includes Kansas 
and Nebraska, in both of which States it appears to be not very 
uncommon. A typical example from Fort Keogh, Montana, is a 
western winter record; while specimens from Santa Clara, Utah, and 
San Francisco Mountain, Arizona, probabl3' show the extent of its 
wanderings to the southwest. 
A series taken ])v Dr. Bishop during the V>reeding season in Towner 
County, North Dakota, is quite uniforml3' more l)rownish above, with 
more cinnamomeous nape than birds from farther north, being thus
