De Vaucouleurs Atlas Description:

NGC 2983 is a good prototype of an outer lens galaxy (Kormendy 1979). The bar is an excellent ansae type that is typical of the late S0s. Two very short, weak spiral arcs break from the ends of the bar, and form the basis for the (s) classification. These arcs do not clearly form an inner pseudoring at the level of the seeing in our Atlas image. The outer disk is almost uniform in surface brightness, and on the east side is very slightly enhanced. It is best described as a lens rather than a ring. The notation, (L), is due to Kormendy (1979).
