APRIL, 1902. LIST WITH NOTES OF THE MAMMALS OF DODGE CO., WIS. 113 
A List, With Brief Notes, of the Mammals of Dodge Co., Wis. 
By E, SNYDER, Beaver Dam, Wis. 
Dodge County, situated in south central Wisconsin, its prin- 
cipal city Beaver Dam, being 65 miles distance from Milwaukee, 
is peculiarly adapted, by its geographical location and topographi- 
cal features, to a large and varied fauna. Within its borders are 
found level fields, heavy hard-wood timber, tamarack swamps, 
hills of considerable elevation, willow thickets, large tracts of 
marshland, some flooded and some now dry, several lakes, some 
of which are bordered by upland pastures, elsewhere by extensive 
marshes, several small streams and occasional weedy, worthless 
tracts of stony hill sides. In these difl^erent areas are found con- 
genial homes for numerous species of small mammals — particu- 
larly the Rodentia. 
The following list embraces 36 species and sub. sp., all of 
which, except the otter and wildcat, have been actually observed 
by the writer. That other species occur within our country there 
can be no doubt. My personal labors have been practically lim- 
ited to a field extending not further than 3 miles from my home, 
near Beaver Dam, and at Fox Lake, 10 miles north. Horicon 
marsh, with its thousands of acres and its surrounding bluffs, has 
never been explored. In the sandy regions about this marsh I 
am told that the Pouched Gopher (Geomys hiirsarius) occurs. And 
in a letter received from Dr. C. Hart Merriam of the Biological 
Survey, dated February 17, 1897, he writes that the Prairie 
Aleadow A'ale (Microtiis anstcrus) and three or four species of 
Long-tailed Shrews (Sorex hoyi, fitmeus, richardsoiii and per- 
sonatus) should occur here. We are also within the range of the 
Star-nosed Mole (Condyhira cristata) . But of these seven species 
only Microtus aitsteriis, Sorex richardsoni and Sorex pcrsonatus 
have come under my observation. 
All specimens of which there could be the least doubt of their 
identity have been named by Dr. Merriam of the Biological Sur- 
vey and his assistants — and I here wish to extend my thanks to 
Drs. Merriam and Palmer and Mr. W. H. Osgood for their kind- 
ness and labors in my behalf. 
In m^y list no particular order of classification is followed, the 
Rodentia being given first because they are the most numerous, 
in species as well as in individuals. The names used are those now
