BIBLIOGRAPHY 
In this Bibliography are given the most important papers re- 
lating to Colorado mammals, including those containing the 
descriptions of species whose type locality is in this State, and 
accounts of the habits of Colorado species. A number of papers 
and books, principally publications of the Biological Survey, which, 
while having no special Colorado references, have some very good 
accounts of the habits of species which do occur in our State, or 
of closely related species, and of their economic relations, have been 
included. One or two strictly technical papers have also been 
included for the benefit of those who may wish to look further 
into those matters. Many articles have been published in sport- 
ing magazines having reference to Colorado mammals. These 
would be entitled to a place in a complete bibliography, but it 
has not been deemed necessary to print their titles here.
