Markarian 315 (II Zw 187) is a classical Seyfert (1.5) galaxy. It has an unusual, narrow, filament of ionized gas extending roughly 65 kpc h(-1) from its center towards the NW. We have mapped the HI associated with Markarian 315 using the VLA in the C-array and find it is located in a 60-100 kpc h(-1) filament which is displaced by 60 kpc h(-1) to the SE of the galaxy nucleus. The velocities of the neutral (HI) gas are interleaved with those of the ionized gas in the main body of the galaxy and those in the ionized filament. This close association between the ionized and neutral gas velocities suggests that the surounding gas is interacting with the galaxy but the disjoint morphology of the ionized and neutral gas implys that the interaction must be complex.
