De Vaucouleurs Atlas Description:

This barred spiral (a Seyfert 2 , Storchi-Bergmann et al. 2001) is interesting in that there is no clear inner ring , pseudoring, or lens around the bar. [The RC3 (r) classification is clearly incorrect.] Instead, the galaxy is mainly a bar plus an unusual outer pseudoring whose morphology does not fit easily into any of the OLR subclasses. The pseudoring is lightly patchy and very well-defined. The bar is excellent, and there is no evidence for leading dust lanes or a nuclear ring in blue light. Rautiainen and Salo (2000) show an $n$-body model with an intermediate halo/disk combination that strongly resembles NGC 1358.
