(2 syl.). Fairies of African mythology, about two feet high, of a white colour, and dressed like the people of Jaloff. Their favourite haunt is the range of hills called The Paps.
When evening's shades o'er Goree's isle extend, The nimble Yumboes from The Paps descend, Silly approach the natives' huts, and steal With secret hand the pounded coos coos meal.
