Gray Wolf

these are doubtless of uncertain validity. In North America 
arc the large Gray or Timber Wolves, and Coyotes or Prairie 
Wolves, both of which have been divided into several forms, 
four for the wolves, and fourteen for the Coyotes in Elliot's 
Check-list, which however are often difficult to separate from 
one another, or to describe so that they can be separated. To 
Colorado however, but one species of the large wolf has been 
ascribed, while there appear to be several forms or varieties 
of the coyote, whose relationships and standing can hardly, 
at the present writing, be defined. 
Canis nubilus (Lat., cloudy). Gray Wolf 
Cants nubilus Say, Long's Exped. Rocky Mts., i., p. i6g (1823). 
Type locality. — Vicinity of Council Bluffs, Pottawattamie County, 
Iowa. 
Measurements. — Total length, 54; tail vert., 11. 
Description. — Gray on the back, many of the hairs black-tipped, 
making irregular wavy black markings, which are heaviest in 
the middle of the back; the under fur is dusky; sides and under- 
parts whitish gray, palest beneath; face gray; ears rather ful- 
vous ; tail gray with black markings similar to those of the back ; 
outside of legs somewhat fulvous, inside like underparts. Wolves 
vary much in color, especially in the amount of the black on the 
back. 
Distribution. — At the present writing I have no information 
which will enable me to separate the range of Canis nubilus from 
that of the other forms of the Gray Wolf, but in Bailey's "Wolves 
in Relation to Stock, Game, and the National Forest Reserves," 
Forest Service Bulletin No. 72, wherein will be found much informa- 
tion about the habits of wolves, is a map showing the distribution 
of wolves through the United States, and from this it appears that 
wolves are found from the western portion of the Dakotas, Nebraska, 
and Kansas westward to the middle of Utah and Arizona, and on the 
north clear to the Arctic Ocean, and are also found on the islands in 
that ocean north of the North American continent; California and 
Nevada are, however, wanting in wolves, except in the extreme 
northeast corner of the latter State. Wolves are found all through 
Oklahoma and Indian Territory; over most of Texas, Arkansas, 
Louisiana, Mississippi, Alabama, Georgia, and Florida. They are 
also along the line between Tennessee and North Carolina; likewise 
in northern Minnesota and Wisconsin, and in the northern peninsula
