So far as known only four specimens of this little Weasel have been 
taken within our limits and all of them in Wisconsin. The records for 
these specimens were first reported by Mr. Henry L. Ward and are as 
follows: A female from Burlington, Racine Co., Nov. 26, 1906, caught 
in the country in the act of killing a Mole (J. c., 1907, p. 63); a female 
captured alive in the town of Sumpter, Sauk Co., Nov., 1902; a male 
taken January 10, 1906, in the town of Merrimac, Sauk Co. (J. ¢., 1909, 
pp. 11-12); and the fourth specimen, which is a female, is in the Milwau- 
kee Museum collection, and was taken near Prescott, Pierce Co., March 
6, IgII. 
The type of this subspecies was taken near Beallsville, Pennsylvania, 
“It is doubtful whether Lapham refers to this species or to some other.
