De Vaucouleurs Atlas Description:

The surface brightness of this galaxy is high and the main morphological features lie on an extended, almost flat distribution of light. The galaxy is most noteworthy for its strong R2' outer pseudoring which is made from two bright arms that begin well off the ends of the bar and which partly overshoot those ends. The overshoot indicates a trace of an R1 component. The pseudoring is lightly patchy and is affected by dust lanes on the near side. The bar is a weak ansae type imbedded in a well-defined inner lens ; this lens causes conflicting interpretations of the variety. There is a trace of a secondary bar (Buta and Crocker 1993a; Erwin 2004).

Sandage and Bedke (1994) state that NGC 3358 ``is Sa, without an external ring." The basis for the (r)-variety in their classification is unclear.
