Arp 167 (NGC 2672 & 3)
Arp 167 is in the class Diffuse Counter-Tails. The Atlas note says "comp. galaxy very condensed, has curved plume." It is not easy to find the counter-tail in the Atlas image and very difficult in my image. There are two tails exiting the smaller galaxy (NGC 2673), one on the southeast side and a fainter one on the north side.
