Black Hills Cottontail

Montezuma, Delta, Garfield, Eagle, Rio Blanco, and Routt Counties. 
It has a considerable range in altitude, from a little over 6,000 feet 
to 11,500 in the Pike's Peak region. The zonal range is mainly 
Transition and the lower edge of the Canadian, but also, as these 
elevations show, reaching well up into Hudsonian at times. In 
southwestern Colorado it overlaps the range of 5. warreni, and in 
other parts of the state that of 5. baileyi, and sometimes two species 
are found at the same locality. 
Habits. — There is nothing specially characteristic about 
the habits of this species, except such as may be due to a 
difference in habitat. In the mountains it is found living 
in the timber and about fallen logs, also in the open spaces; 
and in Routt County I found it out on the open, more level 
ground.

Type locality. — Hill City, Black Hills, Custer County, South 
Dakota. 
Measurements. — As in pinetis. 
Description. — Color as in pinetis but paler, with rufous on legs 
brighter; ears somewhat shorter; skull narrower, with shorter 
rostrum and less interorbital breadth than pinetis, while the bullae 
are somewhat larger. 
Distribution. — This species is found in the extreme west Dakotas, 
most of Montana, Wyoming except the northwest part, extreme 
northwestern Colorado, most of Utah, southern Idaho, northern 
two thirds of Nevada, and just over the central part of the east 
boundary of California; it also ranges over the northern boundary 
of the United States into Alberta and Saskatchewan, Canada. The 
zonal range is mostly Transition and the upper half of the Upper 
Sonoran. In Colorado it has been taken at Meeker, Rio Blanco 
County; at Douglas Spring, Escalante Hills, and Lay, Routt County, 
while specimens from localities not far from these are more or less 
intermediate between grangeri and pinetis.
