The tail of a hare, or of a deer, or other animal whose tail is short, esp. when carried erect; hence, sometimes, the animal itself.
Skelton. [
1913 Webster]
"How the Indian hare came to have a long tail, whereas that part in others attains no higher than a scut."
[1913 Webster]
"My doe with the black scut."
