but existed much longer in northern \Msconsin, northern Michi- 
gan, and ]\Iinnesota.^ There are several reliable records for 
Illinois at about this period, and John Dean Caton states that the 
last account of their presence in northern Illinois known to him 
was in the year 1820 or thereabouts.- Dr. P. R. Hoy records 
their occurrence on the Hay River, Wisconsin, in 1863,^ and there 
is no reason to doubt this statement as it is well known that the 
animals were not infrequently killed in both ^Michigan and ]\Iinne- 
sota at a still later period. 
Alee americanus (Clinton). 
Eastern Moose. 
I see no good reason for excluding the moose from a list of 
Wisconsin mammals. It is a well known fact that the species was 
formerly common in the northern part of the state, and it is not 
entirely an impossibility that a few v^-ill still be found there, as 
they are fairly plentiful in parts of ^Minnesota and have been 
killed within the past ten years in the upper peninsula of Michi- 
gan where they still occur in a number of counties. Hoy states 
that one was killed ''near the line of the Wisconsin Central Rail- 
road'' in December, 1877.^ 
Bison bison (Linnfeus). 
American Buffalo. 
I consider that the buffalo, like the elk and other exteniiinated 
species, is entitled to a place in a list of Wisconsin mammals. The 
former range has been carefully worked out and mapped by the 
historians of the species, notably Allen and Hornaday, and it is 
well known that it formerly ranged over much of the western 
half of the state. Furthermore, Wisconsin is now generally 
credited with the last buffalo east of the ^Mississippi River, near 
the Sr. Croix River in 1832 or 1833.' 
Sciurus hudsonicus minnesota Allen. 
Minnesota Eed Squirrel. 
A careful review of the red squirrels of this region proves 
the validity of this race, to which all the Wisconsin animals be- 
long. True Jiudsoniciis apparently does not occur on the south-
