The orbital structure of a three-parameter family of bar-like potentials is studied, and the orbital structures characteristic of different parameter values are described. Some members of the family of potentials support a remarkable number of semi-stochastic irregular orbits which are qualitatively very similar to regular orbits, but they seem to possess only one isolating integral. Their spectra differ from those of regular orbits in that they are not linelike. There appears to be a correlation between the range of frequencies present in the spectra of semistochastic orbit and the breadth of the scatter of its representative points in a surface of section. It is argued that the discussed box orbits are irregular because the shapes of the isopotential curves of the associated potentials vary rapidly with characteristic radius. The consequences of this situation for the elementary frequencies is investigated and the significance of the results for the dynamics of real galaxies is discussed.
