The discovery of eight planetary nebulae and two possible planetaries, all of low surface brightness, on film copies of a southern-sky survey is reported. It is noted that five of these planetaries are identical to those already discovered by Longmore (1977) and that nine of them very probably belong to the class of old large planetary nebulae. The equatorial coordinates (1950) of the ten objects are provided along with the annual precessions in equatorial and galactic coordinates for the five previously undiscovered objects, the blue magnitudes of the 10 central stars, the nebular dimensions in seconds of arc, the position angles of the major axes, brief descriptions of the individual objects, and identification charts. The objects discovered include one of the largest known planetaries, a nebula with two bright symmetric condensations, a nearly circular ring-shaped nebula, a large nebula resembling a cylinder with an extraordinarily bright central star, and a large faint elliptical nebula with three bright stars near the center.
