Cribrilinidae

Belongs within: Cheilostomata.

The Cribrilinidae are a living family of encrusting bryozoans in which the frontal shield is made up of radiating, hollow spines. Members include the genus Membraniporella, in which the coalesced, depressed frontal spines are recumbent over the membranous ectocyst and partly separated by transverse slits (Bassler 1953).

Characters (Bassler 1953): Zooecia with membranous frontal area covered by two rows of flattened ribs (costulae) directed from their outer border to the median line where they unite intimately but leave a shield (pericyst) perforated by pores or slits. Ovicell hyperstomial.
