With similar technique a new class of potentials connected with Lax method is found which provides the integrability of corresponding 2-dim hamiltonian systems. In addition, some integrable 2-dim systems with potentials expressed in elliptic functions are explored.19 pages, LaTeX, final version to be published in J.Phys.AExactly Solvable and Integrable SystemsHigh Energy Physics - TheoryMathematical PhysicsQuantum Physicstext
