De Vaucouleurs Atlas Description:

NGC 5371 has a weak bar that is somewhat foreshortened by the high inclination . Two strong spiral arms break from the ends of this bar and wind at least 270o, never closing into an outer pseudoring . Although one might recognize an inner pseudoring , as did both de Vaucouleurs and Sandage, this could be a spurious feature caused by perpective on an open spiral pattern. The (rs) classification is more accurate. In fact, NGC 5371 is a very good example of the SAB(s) type. The classification as Sbc is based on the openness and patchiness of the main arms, but it would be an ``early" Sbc compared to others in this section.
