De Vaucouleurs Atlas Description:

This ``DDO dwarf" has a well-defined, somewhat distorted bar, and a clear inner pseudoring of the bracket type. The outer disk includes only weak spiral features. In this case, the bar is relatively well-centered, but the appearance is similar to an SBm , thus we adopt the classification Sdm. The galaxy very much resembles NGC 3906 .
