was classified as elliptical on the PSS, due to its featureless appearence. However it is one of the strongest $\rm H\alpha$ emitters, with 82 $\rm \AA$. This emission, almost entirely nuclear, is probably caused by the gravitational interaction with its companion, and/or with a third fainter object in the vicinity (clearly seen in the net frame) whose redshift is not presently available.

160050: at the time of the observation presented in this paper (April 1995) a redshift of 5319 $\rm km~s^{-1}$ was available (Tifft & Gregory 1976). Thus we used the 6683 $\rm \AA$ filter to get the on-band and the 6603 $\rm \AA$ for the off-band frame. After reducing the data we found, to our disappointment, that more flux and more structure showed up in the off-band frame. However, one year later we obtained a spectrum of this galaxy for another project. To our surprise we found that the true redshift is 2496 $\rm km~s^{-1}$. Thus it turns out that our $\rm H\alpha$ measurement is useful but with reversed filters.

160055: the off-band frame was contaminated by some stray-light from a nearby bright star which produces a faint diffuse feature at the SE edge of the galaxy. The net
