We present the results of an isophotal shape analysis of galaxies in the Comaand Perseus clusters. These data, together with those of two previous papers,provide two complete samples of galaxies with reliable Hubble types in richclusters: 1) all galaxies brighter than m_b = 16.5 falling within one degree(=2.3 Mpc) from the center of the Coma cluster (187 galaxies), 2) all galaxiesbrighter than m_{Zwicky}=15.7 in a region of 5 deg 3' times 5 deg 27' aroundthe center of the Perseus cluster (139 galaxies). These two complete samplescover 5 orders of magnitude in galaxy density and span areas of 91 and 17Mpc^2, clustercentric radii up to 2.3 and 6.4 Mpc, for Perseus and Comarespectively. They will be used in subsequent papers to study the dependence ofgalaxy types on cluster environment and as reference samples in comparisonswith distant clusters.Comment: A&AS, in press. 14 pages including 2 figures and 5 tables, A&A macro
