Barghest
barghest (also barguest) In English folklore, a spectral hound said to exist in Cornwall and northern England. As a DEATH OMEN, it manifests as a bear or large dog. Inhabitants of Lancashire call it the Shriker, after its shrieks emitted when it is invisible, and Trash, after the splashing sounds it sometimes makes when it walks. See Black Shuck; Whisht Hounds.
