O III forbidden line observations of the nearby quasar MR 2251-178 were made with the Taurus II imaging Fabry-Perot instrument. The line emission around the quasar is found to consist of several regions of high surface brightness located in two half-cones with an opening angle of about 37 deg extending 12-16 kpc from the quasar. The velocity field of this region shows multiple velocity components at several positions. Emission line diagnostics indicate that both the central narrow-line region and the extended emission line region are most likely photo-ionized by radiation with a hard spectrum. The presence of a few line emitting 'blobs' further away from the quasar, at distances of 45 to 80 kpc and counter-rotating with respect to the gas nearby the quasar, is confirmed. Emission extending out to some 170 kpc from the quasar towards the SE as reported earlier is not observed.
