Not. Royal Astron. Sco., Gemini Preprint #43 ABSTRACT Photometry has b een obtained for magnitude limited samples of galaxies in the two rich clusters Ab ell 665 (37 galaxies) and Ab ell 2218 (61 galaxies). Both clusters have m a redshift of 0.18. The limiting magnitude of the samples is 19 in the I-band. Sp ec- troscopy has b een obtained for seven galaxies in A665 and nine galaxies in A2218, all of whichalsohaveavailable photometry. Sp ectroscopy has b een obtained for two additional galaxies in A2218, one of whichisabackground galaxy.
