In a recent experiment by Chen, Roesler, and Mochel, a new transition was found in the superlluid 4 He film on a hydrogen surface, with a transition temperature below the Kosterlitz-Thouless transition temperature. We suggest that the intermediate phase between these two transitions is a lattice form by the superfluid vortices and antivortices. The transverse phonon mode or this lattice is identified with the «extra mode» detected in the third sound measurement
