We describe the morphological composition of a sample of 518 galaxies in thefield of CL1358+62 at z=0.33, drawn from a large HST mosaic covering 53 sq.arcmin. The sample is complete to I=22, corresponding to M_V=-18.5 in the restframe. The galaxies have been independently classified by the authors of thispaper and by Alan Dressler. For galaxies with I<21, the two sets of classifiersagree on the total early-type population, but disagree on the S0/E ratio. Wediscuss the constraints on morphological evolution and the implication of thediffering S0/E ratios. We use our large body of spectra to make thecorrespondence between morphological and spectral type.Comment: includes 10 fig
