Wisconsin near Lake Michigan ; in these parts of the state it out- 
numbers Putorhis noz'cboracensis. 
Putorius rixosus allegheniensis (Rhoads). 
Alleghenian Least Weasel. 
The single specimen of this rare weasel which has been taken 
within our boundaries has already been recorded by Mr. Henry 
L. Ward, (6) ; this specimen was taken November 26, 1906, near 
Burlington, Racine County. Specimens of typical rixosus have 
been taken in Minnesota, and additional collections and study may 
prove the two forms, rixosus and allegheniensis, to intergrade in 
central or northern Wisconsin. 
Putorius noveboracensis Emmons. 
New York Weasel. 
Putorilis noveboracensis is the most common weasel in the 
southern and central parts of the state, westward to the Mississippi 
River ; eastward, in the vicinity of Lake Michigan it does not ap- 
pear to be so common. 
Mustela americana Tnrton. 
Pine Marten ; American Sable. 
The pine marten is now practically extinct in Wisconsin. I 
have seen only three specimens which have been taken in the state ; 
one of these, a trapper's pelt, was taken in Vilas County in the 
winter of 1904- 1905. Dr. H. V. Ogden has two skulls in his col- 
lection ; one taken at Fisher Lake in Iron County from an ani- 
mal killed in December, 1897; the other was taken near Drum- 
mond in Bayfield County. 
Procyon lotor (Linnaeus). 
Raccoon. 
Procyon lotor is distributed over the entire state, but it is most 
abundant in the western part ; in the northern pine regions it be- 
comes less common. Raccoons prefer oak woods in the vicinity
