In continuation of former work (Feitzinger 1980) the morphological structure of 68 SB(s)m systems, greater than 2!5 on ESO/SRC survey plates, was investigated. Three morphological features should be mentioned:

  1. 1. Stellar bars located asymmetrically with respect to the disk are found in 70% of the cases; the displacement relative to the disk diameter is Λ = 0.1 − 0.35.

  2. 2. The disk is populated in 45 % of the cases by chains of HII regions (spiral arm filaments).

  3. 3. Though not very frequent nearly 25 % of the SBm systems have a dominating HII region near the outer periphery and predominantly near one end of the bar.
