ITiiitcd Statos National iNInseuni, proves l)ovond a doiil>t what was 
already more than surmised — that this name must ))e used for the 
Oincorix inhabiting- Colorado, W3'oming% Montana, and adjacent 
territoiT. Avdiich iVIr. Henshaw described as arenieola.^ The tA'pc of 
<ii\'iiico](( came from Denver, Colorado, being apparently" of the form 
breeding at that place, and although inclining' somewhat toward the 
race fi'om Assiniboia is much nearer IcHcohvnia. The two additional 
males from Fort Randall, collected b}- Dr. Coues on March s and 12, 
IS7H, respectively, and mentioned above, are substantially identical 
with the type, though considerably larger. These three specimens, 
notwithstanding the late date, possil)b; do not represent the l)reed- 
ing birds of the region, for they appear more closeh' to reseml)le 
(wamples from northern Colorado. The breeding birds from western 
Kansas and Nebraska, eastern Montana, extreme eastern Wyoming, 
central and western South Dakota are intermediate between Icacohp^oa 
!Uid I iifJn/iii/a^ though nearer the former, being in color al)ove some- 
what more brownish than t'/if/it/inia^ this evident both on the nape 
and back. Some specimens from Dickinson. North Dakota, are 
essentially similar. The area of inosculation with pridicola is not 
illustrated by the material at hand, but it nuist of necessity be limited, 
for examples from Pendennis, Kansas; Ellsworth, Sidney, and Alliance, 
Nebraska, show practically no approach to the eastern race, while 
jn'aticoht from Strong, Kansas, is very far from intermediate. Speci- 
UK^ns from northwestern Montana approach incrrllll in the darker 
upper surface, but most of them appear to be nearer the present form. 
The same tendency is evident in birds from Big Butte, Idaho, and P^lko, 
Nevada, though to a less extent. A single adult breeding male from 
Roswell, New Mexico, seems to )w typical hucohpina^ but similar exam- 
ples from both Alpine and Amarillo, Texas, are somewhat more rufes- 
cent above. Birds from central and southwestern Nevada avcrag^e 
d(M'idedly smaller and somewhat more grayish on the back than those 
from central Colorado, showing thus an approach to ammophila. while 
more to the southward in Nevada the tendency seems to be toward 
leucanHiptila^ since some specimens are almost indistinguishable from 
those of eastern (yolorado and western Kansas, intermediate ])etween 
leucolcevia and enthymia. The birds examined from Antelope Island, 
Great Salt Lake, Utah, are conspicuously redder than those from the 
surrounding region, being thus curiousl}" similar to oce!d<iifali'<, though 
separated from this form by a wide area. 
How far to the northward of the United States the range of leueo- 
licma extends can not Ije definitely determined from the material at 
present available, but a very typical autumnal specimen from Calgary, 
Alberta, shows that it reaches at least this latitude; and specimens
