---------Two new aberrant sessile graptolites from glacial boulders are described. The Silurian form, Urbanekicrusta
reversa gen. et sp. n. is interpreted as a crustoid (hormograptid?) graptolite, whereas the Ordovician (?),
Maenniligraptus ursulae gen. et sp.n., represents presumably an unknown order of Graptolithina.
