In 1906 the U. S. Department of Agriculture published faunal bulletin No. 26 by Arthur H. Howell, Assistant Biologist of the U. S. Biological Survey on the "Revision of the Skunks of the Genus Spilogale". According to this report the only species referred to Iowa is Spilogale interrupta Raf., three specimens of which were examined from this state; one of which came from Gladbrook, and two from Marshalltown. His distributional map shows the range of this species as extending to southeastern Minnesota on the following statement by Mr. E.T. Seton "He (E. T. Seton) states that two were killed by a trapper in March, 1904, on the Mississippi River 40 miles southeast of Minneapolis. The animal was previously unknown to trappers in that region, so that this is doubtless an instance of recent extension of range."
