TUKULOR (TUCULERS)  , the name, by some said to be the French tout-couleur, for the negro half-castes of Senegal, who are principally of Fula-Wolof descent . By others the word is identified with Tacurol, an old name of the country, which took the form of Tacurores in the Portuguese writers of the 16th century . The Tukulor are settled chiefly in the Damga, Futa, Toro and Dimar districts of Senegal, and are remarkable for their fanaticism as Mahommedans . An intelligent, energetic and fierce people, they offered strenuous opposition to the conquest of their country by the French in the latter half of the 19th century .
