De Vaucouleurs Atlas Description:

The seeing is very poor on the Atlas image, but this galaxy has several important features. The main features are the two clear pseudorings. These have different projected major axes and so have different intrinsic shapes in the galaxy plane. The bright inner pseudoring is formed in part by two arms breaking from the ends of an ansae bar. Both arms bifurcate into segments that either form the rest of the inner pseudoring , or go into forming the outer pseudoring . Most remarkable is that the two outer arms form an R1' OLR subclass pseudoring with respect to the major axis of the inner pseudoring, not with respect to the major axis of the bar. Thus, NGC 619 is in the special class of misaligned bar-ring galaxies , of which ESO 565-11 is another example.
