We present an analysis of the spatial orientations of 851 galaxies in 7 Abell clusters of BM type III (type III in the Bautz-Morgan system). Anisotropy is found in all 7 clusters. It is found that the spin vector orientations of the galaxies in the clusters of BM type III tend to be oriented both parallel (Abell 1412, Abell 2048 and Abell 4038) and perpendicular (Abell 2061, Abell 2065, Abell 2151 and Abell 2197) to the local supercluster plane. The spin vector projections of galaxies in 5 clusters (Abell 2061, Abell 2065, Abell 2151, Abell 2197 and Abell 4038) is found to be oriented perpendicular to the Virgo cluster center.
