On September 6, 1910, an old Skunk with three young, the latter 
about two thirds grown, were taken by Mr. W. E. Snyder at Beaver 
Dam, Dodge Co., Wisconsin, and the specimens were sent to me for 
determination. The skull of the adult approaches avia, but has a 
palatal spine slightly indicated; the tail is black except a few white 
hairs near the middle; the end of the tail is blunt and entirely black. 
The young show some slight cranial differences; in two of them a 
palatal spine is slightly indicated; in the third it is entirely absent. 
All of the young have the white stripes of the body extending on base of 
tail and all have the tails terminating with a long white pencil (4 to 5 
inches long).

The Northern or Hudsonian Skunk is supposed to be the common 
form throughout the greater portion of Wisconsin. Hollister states that 
out of 28 Skunks collected near Delavan, Walworth Co., 25 were 
hudsonica and only 3 avia (J. c., p. 141). Jackson says all the specimens 
he examined from various parts of the state proved to be hudsonica 
(7. ¢., p. 28). While the majority of Wisconsin Skunks may probably
