Two-dimensional tunneling is studied for a model potential V( Q, X) = V,(Q) t tl(Q'-Qa)X\*+ @X4. Vo(Q) is a symmetric double-well potential which has two transition states placed symmetrically in the dividing line. Extremal trajectories are shown to be of three types replacing each other at bifurcat
