Yumboes are supernatural beings in the mythology of the Wolof people (most likely Lebou) of Senegal, West Africa. They closely resemble European fairies. Their alternatively used name Bakhna Rakhna literally means good people, an interesting parallel to the Scottish fairies called Good Neighbours. Yumboes are the spirits of the dead and, like many supernatural beings in African beliefs, they are completely of a pearly-white colour. They are sometimes said to have silver hair.
Chinese mythology has white foxes and white tigers.
