This snake (d. early 1900s) was presumably a pet of pure-blood wizard Morfin Gaunt. It killed by it's owner sometime before 1925.
History
This snake somehow came into Morfin Gaunt's possession in the late 1800s or early 1900s. It had a very short life as Morfin killed it sometime before 1925, and then nailed it to the door of the House of Gaunt, much to everybody's frightening.
