A set of criteria was developed for finding short-period comets among those for which only parabolic orbits are available. These criteria indicate that the basic Catalogue of Cometary Orbits by Marsden (1989) includes about 18 such cases with revolution periods less than 20 years. About 15 of them were observed before the discovery of the first known object of this type. One of them, comet 1678, was already definitely identified with P/d'Arrest (Carusi et al., 1991). Another 14 of them were almost certainly of short period. For comets 568, 1080 and 1457 II a short revolution period appears probable, for comets 1245, 1293, 1618 I and 1618 III possible, and for comets 390, 1757 and 1860 IV not impossible.
