Abstract. The orbitoidal larger foraminifer Omphalocyclus maldonensis n. sp. is described from the Maldon Inlier of northwestern Jamaica, being the first record of this genus from the island. The limestone in which it occurs contains the Upper Cretaceous (Upper Maastrichtian) Titanosarcolites rudist fauna, together with larger foraminiferal specimens identified as Orbitoides megaloformis Papp & Küpper. The new species differs from Omphalocyclus macroporus, the only other widely recognized species, in possessing a much smaller nucleus. At least some of the earlier records of Omphalocyclus from the Upper Cretaceous of Venezuela and Cuba should probably be referred to O. maldonensis.
