The motion of atoms in a dark magneto-optical lattice is considered. This lattice is formed by a non-uniformly polarized laser field in the presence of a static magnetic field. Cold atoms are localized in the vicinity of points where dark states are not destroyed by a magnetic field. As a result the optical interaction tends to zero (dark or gray lattices). Depending on the field configuration such a lattice can exhibit one or two-dimensional periodicity. It is shown that in 1D and 2D dark
