Abstract Three new cases where smaller galaxies appear to be connected by luminous filaments to larger galaxies are presented. The central galaxy-interacting companion redshifts are: (a) 6,000 and 16,400 km/s; (b) 4,600 and 37,300 km/s (NGC 53 + companion); and (c) 10,400 and 46,900 km/s. These should be added to the original member of the class: (d) 8,700 and 16,900 km/s (NGC 7603 + companion). All cases appear to be physically connected, but the most striking case is (b) above. Direct photography shows the central galaxy to be very distorted in a way not accounted for by other galaxies in the vicinity. The luminous filament reaches from the very perturbed regions to the companion, and the companion has a spectrum exhibiting unusually early hydrogen-absorption lines. The latter are characteristic of the young stellar population companions usually found near large galaxies.
