Crisiidae, a family of Cyclostomata (q.v.), in which the colony (Zoarium) is branching, consists of a series of jointed segments, each of which is composed of one or two series of tubes. Crisia cornuta (Linn.) or the "Goat's Horn Coralline" and Crisia eburnia (Linn.) or the "Tufted Ivory Coralline," are the two best known English species of this family.
