De Vaucouleurs Atlas Description:

This galaxy can be considered a prototype of SB(s)cd. The bar is very well-defined and includes considerable asymmetry and some dust. The two main arms break perpendicularly from the bar, and although relatively ill-defined, these arms form an (R₂^') pseudoring in the outer disk. This is one of the latest types showing this kind of morphology. No nucleus is seen in blue light. The approximate B-V color index map shows considerable recent star formation in the bar, and a broad, off-centered dust patch dividing the bar. De Vaucouleurs and Freeman (1973) considered the dividing dust-patch morphology characteristic of the most late-type barred spirals , such as those of the Magellanic type. The presence of active star formation in the bar is generally found mainly in late Hubble types (Martin and Friedli 1997).
