The structures which would govern these limiting cases are then not covered by the work of section 2 and it would be interesting to identify and analyse these structures. On the second branch of solutions ( labelled II on figure 3 ) it is immediately seen that only positive frequencies are found. In particular, we remark that as increases and approaches 0. 187 ( corresponding to a disturbance waveangle of 10. 6 ) the wavenumbers and frequency become small. This suggests the existence of a longer wavelength disturbance with a small wavespeed and this structure corresponds to that of the upper-branch mode investigated in ( 12 ). In this paper, small perturbations with wavenumbers O ( R, ) and wavespeeds O ( R- ) were shown to be possible at waveangles between approximately 10. 6 and 39. 6 . As decreases from p: in our current problem and becomes negative the convergence of the numerical scheme em-ployed becomes increasingly difficult to achieve and only the neutral solutions which can be reliably located by our method have been shown in figure ( 3 ). Indeed, for sufficiently negative the basic profile is monotonically increasing and has no point of inflexion. At these values of parameter, no neutral solutions of the sought type can exist and so it suggests the existence of some p, 0 at which our solutions cut out. It is seen from figure ( 2 ) that as decreases from zero the neutral disturbances have two critical layers up to the point where the basic velocity is no longer non-monotonic. Then the two critical layers must merge, cease to remain asymptotically distinct and a fresh analysis is required.
