Colonial. Inverted bell-shaped zooids mounted upon non-contractile branching stalk. Peristome with large conspicuous lip bearing four to six ciliary rows. Stiller (1971) considers the presence of the large number of peristomial ciliary rows as being insufficient to erect it as a separate genus and considers it to be a homonym of Epistylis. Most easily confused with Epistylis which has only one or two turns in the peristomial ciliary rows. May also be mistaken for Opercularia and Orbopercularia which are without a lip to their peristomes.
