Two short runs of spectral data on EX Hya have been obtained. One of these provides a high time and wavelength resolution data set covering a cycle in the 67 min modulation and containing a deep eclipse. The other was acquired shortly preceding one of the relatively rare outbursts of this system. Examination of these data sets confirms features noted in other studies. The 'accretion curtain' model of Rosen et al. (1988) is discussed and shown to be qualitatively consistent with the observational data in both the optical and X-ray bands.
