Surface photometry of 37 nearly edge-on, nonbarred E-S0 galaxies is presented. Inner rings are found in more than half of the S0-classified objects. An 'outer lens' may be seen in nine objects, seven showing both outer lens and 'ring-lens'. Preliminary statistics are given on disks which are fully embedded in the envelope, mixed with it, or extend outwards without a noticeable envelope. The E-classified galaxies in the sample show no ring, and all the disks are fully embedded except in one case. The f4 asymmetry expressed by small trends in major axis position angle and nonzero value of Carter's coefficient f4 of sin 4 omega is clearly shown by 10 objects in the sample.
