De Vaucouleurs Atlas Description:

This galaxy has a very bright inner pseudoring made of two tightly wrapped spiral arms. It is open near its projected minor axis, and we use the underline notation to indicate that it is nearly a true inner ring . Most remarkable is the small bar in the nuclear region. This feature cannot be the primary bar of the system because it is so small compared to the size of the inner pseudoring . Instead, the feature could be a secondary bar , and its presence could signify that NGC 3434 's primary bar has largely dissolved. This primary bar would have crossed the major axis of the inner pseudoring . The central bar is remarkable for its ansae character, something more typically seen in primary bars. The outer arms are well-defined and patchy, and show some asymmetry .
